The ocean skin temperature was measured with an accuracy believed to be better than 0.1 degrees C. The surface reflectivity/emissivity was determined as a function of view angle and sea state. The radiative properties are in good theoretical consistency with in situ measurements of ocean bulk temperature and the meteorological observations made from the oceanographic vessel. The AERI and in situ measurements provide a strong basis for accurate global specifications of sea surface temperature and ocean heat flux from satellites and ships.

To determine whether RVF infection had spread to the Nile delta region of the country, we carried out a cross-sectional survey of 1181 occupationally exposed abattoir workers (97% male; age 10-72 years) in 15 governorates of Egypt in November 1993. The overall prevalence of anti-RVF virus IgM antibody was 2% (range: 0% (7 governorates) to 10%). The highest prevalences were in Ismailia (10%) and Sharqiya (8%) Governorates. None of the seropositive subjects reported having experienced an episode of fever in the 2 months prior to the study The prevalence of antibody was significantly higher (P < 0.05) among workers employed in high-risk jobs such as cutting animals' throats (relative risk (RR = 2.24)) and handling animal parts (RR = 2.37). The findings suggest that abattoir workers represent a useful sentinel population for surveillance of RVF. C1 MINIST HLTH CAIRO,INFECT DIS CONTROL PROGRAMME,CAIRO,EGYPT.

These features are often the principal reason for the large scatter evident in fracture toughness measurements which, in extreme cases, can mask the fundamental relationship between cracking resistance and global material properties. The SEM stereo-section fractography (SSF)(1) technique can be used to carefully evaluate these local inhomogeneities through simultaneous observation of both the fracture surface and the underlying microstructure. By sectioning the fracture surface close to the cleavage initiation site (within 10 mu m), and perpendicular to both the fracture surface and the precrack front, a direct correspondence between initiation and the local microstructure can be established. Information obtained from this technique can provide quantitative input about important, local microstructural features which can then be used to calibrate or create realistic micromechanical models. A compendium of SSF results is presented herein for cleavage cracking in disparate materials (A533B steel plates, MIL-70S multi-pass weldments, and Ti6Al4V forgings), under various testing conditions. In each case, the SSF technique was able to unambiguously identify the dominant, local features which triggered cleavage initiation. C1 USN, Ctr Surface Warfare, Bethesda, MD 20817 USA.

Experiments were conducted in two stages: a detailed study of the concept of utilizing vortex combustion for incineration in a small scale flame burning gaseous fuel and an extension to a more practical system using liquid fuel with significantly higher heat release. The open loop active control system is based on the concept of combustion in periodic axisymmetric vortices. Acoustic excitation is used to stabilize coherent Vortices in the air flow. Acoustic excitation and automotive fuel injectors, were used to control gaseous or liquid fuel injection, respectively, such that the fuel is introduced into the air vortices at the right time during their formation. It is shown that this control methodology leads to improved waste destruction. A gaseous fueled actively controlled 4.5 kW incinerator was able to surpass 99.997% DRE (destruction and removal efficiency) even when the waste surrogate (gaseous benzene) constituted 66% of the total fuel content. Parameters found critical to maintenance of high DRE in the gaseous fuel/waste tests were the fraction of circumferentially entrained air and the phasing angle of fuel injection with respect to the air vortex roll-up. The control methodologies studied using gaseous fuel and waste were extended to liquid afterburner/incinerator of 56 kW energy release. The DRE for liquid benzene exceeded 99.999% in this system when combustible to air ratio was kept below 0.91. Again, the use of synchronous fuel injection into coherent air vortices was found to be critical to maintaining high DRE. Even more crucial was good atomization of the liquid fuel/waste mixture.

The jets studied are compressible (subsonic) and consist of hydrogen diluted in nitrogen emerging into a quiescent background of oxygen also diluted in nitrogen. The numerical model involves space/time developing jets, species- and temperature-dependent diffusive transport, and finite-rate reduced chemistry appropriate for hydrogen combustion. The study focuses on investigating the role of exothermicity and relaminarization in controlling the jet development, and the dependence of these effects on Reynolds (Re) and Lewis (Le) numbers. For the flow regimes studies, considerable viscous damping effects are found for the reactive jets because of exothermicity and the monotonically increasing dependence of viscosity with temperature-in contrast with slight stabilizing effect of reducing Re in absence of chemical reactions. The reactive simulations predict generally higher jet temperatures and significantly reduced jet entrainment associated with lower Re and jet Le less than unity.

Afterburning reaction was observed under certain conditions in which excess fuel was present, as a result of the fuel-rich gas mixing with fresh oxygen in the surrounding air. By fitting an adjustable-geometry cavity at the nozzle exit, the jets were passively excited at various frequencies via a flow-induced cavity resonance mechanism. Mie-scattering Bow visualization and chemiluminescence measurements were used to measure the response of the excited jets under both afterburning and non-afterburning conditions. The effects on supersonic mixing and afterburning reaction were quantified in terms of changes in initial shear layer growth rate and chemiluminescence from the flames. Three cases having similar compressibility conditions but with different exit temperature and composition were investigated; the shear-flow convective Mach numbers ranged between 1.3 and 1.4 for all cases while the exit temperature ranged between 1300 K and 1510 K. Mie-scattering images revealed that the excited shear layers in the near-jet region rolled up into organized large-scale structures, which are extraordinary at such a high convective Mach number. The dynamics of the large coherent structures was manipulated by varying the excitation frequencies. The results showed that Bow excitation increased the initial shear layer growth rate by an amount that was sensitive to excitation frequency. For the present compressibility condition, the increase of as much as 50 % was observed when the Frequency was at or near the jet preferred mode. However, the net effect on afterburning reaction was determined by a delicate balance between afterburning suppression due to large-scale cold-flow entrainment that caused quenching and afterburning enhancement which was a result of faster mixing. The results showed that global emission from the afterburning flames could be either reduced or increased from the natural state by as much as 80% depending on the excitation frequency and flow conditions. While the effect of excitation was strongest when the frequency was within the jet-preferred-mode bandwidth, the afterburning reaction in general appeared to be intensified at higher frequencies.

Rhinocerebral mucormycosis was associated with diabetic ketoacidosis in 3 patients and with acute lymphocytic leukemia in 1 patient. In all 4 patients, mucormycosis progressed even after extensive surgical debridement and initiation of treatment with amphotericin B. The addition of hyperbaric oxygen therapy was associated with a decline in the progression of intracranial mucormycosis and limitation of ablative surgery.

The estimator uses a small set of bandwidths rather than a single global one as in the standard kernel estimator. It uses a set of filtering functions which determine the extent of influence of the individual bandwidths. Various versions of the idea are discussed. The estimator is shown to be consistent and is illustrated by comparison to the single bandwidth kernel estimator for the case in which the filter functions are derived from finite mixture models.

The shear layer is formed by two co-flowing streams past a splitter plate. The emphasis of this work is on examining how the particle dynamics are affected by the large-scale coherent structures in the initial development of the instabilities in a spatially-developing mixing layer. The two-dimensional time-dependent gas-phase equations are solved numerically using the explicit flux corrected transport (FCT) algorithm in the low-Mach-number regime. The dispersion of particles is studied by following their trajectories in the shear layer. A detailed visualization of the Bow field, dominated by the large structures, and of the particle dynamics is performed to obtain qualitative as well as quantitative information on the particle dispersion. The visualization clearly reveals the capturing of the small and intermediate size particles by the vortical structures. The small size particles, however, remain captured in the vortical structures, whereas the intermediate size particles are flung our of them, leading to their enhanced dispersion. The large particles remain mostly unaffected by the large eddies. The quantitative results obtained indicate that the above behavior can be well correlated with the Stokes number (S-t) values; the optimal dispersion corresponds to the Stokes numbers in the range 0.1 < S-t < 5.0. This is in qualitative agreement with previously reported experimental as well as numerical results. The results also indicate that the particles injected in the faster stream exhibit higher dispersion compared to those injected in the slower stream. This divergence in the dispersion behavior is related to the asymmetric entrainment as reported by some earlier experimental and numerical studies.

The SAGE II data provide an estimate of interannual variability of water vapor in the stratosphere, The SAMS data are appropriate for the upper stratosphere and lower mesosphere. We combine these two data sets with those from the Nimbus-7 Limb Infrared Monitor of the Stratosphere (LIMS) experiment to update the COSPAR interim reference model for water vapor. Water vapor profiles from the Spacelab 3 Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment, ground-based microwave, and in situ balloon and aircraft measurements have been used to check the quality of the satellite data sets, The updated reference model is given as a function of latitude and pressure altitude and now covers all four seasons, Tabulations are included for these seasonal water vapor mixing ratios (in ppmv) and their estimated errors (in percent).

Recent experimental and technological innovations afford the opportunity of dramatically improving previous measurements. We will exploit recent high resolution thermometry techniques which provide a resolution of the lambda point to within 10(-9) K. In addition, the development of glass channel arrays with less than a one percent deviation throughout the entire array and high packing densities will provide a containment sample that is much improved over previous work. Finally, we will employ a high resolution pressure sensor with a SQUID readout to detect the small signal associated with a close approach to the transition.* C1 USN,RES LAB,DIV OPT SCI,WASHINGTON,DC 20375.

After establishing the validity and relevance of the phase diagram to these materials, the anisotropy factor is extracted from the slope of I-c(1)(T) (the current defined by the onset of resistance).

We present here a general framework for analyzing these, based on Liouvillean Quantum Field Dynamics. Thus a multifunctional extension of the time-dependent density functional approach to many-body problems is set up. We also generalize the time-dependent non-equilibrium Green function method of Schwinger and Keldysh including all the relevant fields. We thus enlarge the context of the Phi-derivable, effective action functional theory of Baym for transport phenomena involving all relevant fields consistent with the conservation laws. This formalism is essential in understanding very-short time quantum dynamics of coupled fields of electrons, ions, and electromagnetic fields, as in nanoelectronic and optoelectronic devices, quantum dots in intense laser beams, micro-cavity quantum electrodynamics, as well as strongly coupled electron-phonon (high T-C), electron-photon (laser-atom systems), and molecular dynamic systems.

The algorithm utilizes strain information from a set of sixteen fiber Bragg grating (FBG) sensors mounted on the plate so that all sensors measure strains along the clamped-free direction. The sensors are interrogated using a wavelength division multiplexing scheme, and measured strains are converted to full-field displacement. The algorithms used to interrogate the sensors, perform the strain-displacement calculations and generate a real-time (approximately 60 Hz) mesh of displacement values are encoded in a C program.

As the computer capabilities of the ephemerides offices and the users of ephemerides have improved, the methods of determining and the accuracies of ephemerides have changed and the medium and representation of the ephemerides provided to the user have evolved. Ephemerides have been provided in the form of theories, tables, tabulations, polynomials, graphics, and subroutines by means of the printed page, punched cards, magnetic tape, floppy disks, CD/ROMs, and electronic mail. As mathematical techniques and computer technology continue to develop and the requirements for ephemerides evolve, the methods of representing and diffusing ephemerides will continue to improve.

This includes both phenomena timings as well as tangent plane astrometry. In most cases this change has been for the better, but in some areas there has been no gain - even a loss. We will review this change in terms of the recent history of satellite observations. The impact of the CCD will be discussed in terms of its applications, and the increase in precision it affords. Finally, a few things will be said about future directions, especially about spin-off applications. RP Pascu, D (reprint author), USN OBSERV,WASHINGTON,DC 20390, USA.

The beamforming problem is defined as a three dimensional solution space by generating a cube structure with sonar array elements as one dimension, the required beams in another dimension, and the time samples in the third dimension. The given approach maps the problem cube into the MasPar structure using a modified one-to-one mapping and uses two MasPar Fortran 90 intrinsic array functions to generate the solutions to the beams. Simulation results are provided for different array and beam sizes.

Previous studies have indicated that strong sulfonic acids, when added to fuels that are then subjected to thermal stress accompanied by oxidative aging, tend to produce quantities of insoluble sediment. This work presents results obtained when dodecylbenzenesulfonic acid (DBSA) is added to a blended diesel fuel. We find that a fraction of the insoluble material forms immediately on addition of the acid and we investigate the effects of accelerated aging and DBSA addition on other insolubles related fractions of the fuel sample. Evidence is presented that opens to question the interpretation of results obtained when a reactive reagent is added to a chemical system as complex as a fuel. C1 USN,RES LAB,WASHINGTON,DC 20375.

Both biosensors are rapid, sensitive and easy to operate. The first sensor, the continuous flow immunosensor, is based on displacement of fluorescently-labeled antigen from antibodies immobilized on beads. Antigen is injected into a flow stream that passes over a 100 mu L bed volume of antibody-coated beads saturated with fluorescently-labeled antigen. The displacement of the labeled antigen causes an increase in fluorescence, proportional to the antigen concentration, to be observed downstream. The other sensor, the fiber optic biosensor, utilizes long, partially clad optical fibers. Antibodies are immobilized onto the fiber core in the unclad region at the distal end of the fiber. Upon binding of antigen and a fluorescent molecule, a change in the fluorescence signal is observed. For small molecules, competitive immunoassays are performed in which a decrease in the fluorescence signal is observed which is proportional to the antigen concentration.

Our system is neither fully autonomous nor fully teleoperated. It is designed to make effective use of the human's abilities within the present state of the art of autonomous systems. Our robotic agents refer to systems which are each equipped with at least one sensing modality and which possess some capability for self-orientation and/or mobility. Our robotic agents are not required to be homogeneous with respect to either capabilities or function. Our research stresses both paradigms and testbed experimentation. Theory issues include the requisite coordination principles and techniques which are fundamental to a cooperative multi-agent system's basic functioning. We have constructed an experimental distributed multi-agent architecture testbed facility. The required modular components of this testbed are currently operational and have been tested individually. Our current research focuses on the agent's integration in a scenario for cooperative material handling. Copyright (C) 1996 Elsevier Science Ltd C1 UNIV PENN, GRASP LAB, PHILADELPHIA, PA 19104 USA.

This system will enable future armored and mechanized units at battalion and below to train in virtual environments on a digitized battlefield The major tasks for planning a days' training include the following. First, personnel from the unit undergoing training select training scenarios to be conducted during each training day. Next, the training scenarios are scheduled throughout the planning horizon where multiple scenarios may be scheduled simultaneously. Finally, the type and quantity of training resources for conducting each training scenario are identified and scheduled. Resource quantities vary by training scenario type and may vary within a scenario type as well. CCTT training resources include simulator modules, computer workstations, workstation operators (people) and computer-generated, semi-automated forces (SAF). This paper discusses the development of a hybrid expert system prototype for scheduling training in the new CCTT facilities.

Efforts which reduce repair costs, system down time, and the reliance upon outside technical representative are of particular interest. The development of the MK92 Maintenance Advisor Expert System (MK92 MAES) is one such effort. This paper describes the design and development of the MK92 MAES for the diagnosis and repair of the MK92 MOD fire control system deployed on U.S. Navy guided missile frigates. System development is presented in terms of an expert system life cycle model which includes a thorough cost/benefit analysis, a novel approach for knowledge acquisition, an implementation strategy using a visual expert system development environment, and a phased deployment strategy. The system was developed by faculty and graduate students at the Naval Postgraduate School in cooperation with the Naval Warfare Center Port Hueneme Division.

When knowledge is elicited from multiple experts, it is necessary to combine the multiple sources of expertise in order to arrive at a single knowledge base. In this paper; we present and compare five techniques for aggregating expertise. An experiment was conducted to extract expert judgments on new product entry timing. The elicited knowledge was aggregated using classical statistical methods (logit regression and discriminant analysis), the ID3 pattern classification method, the k-NN (Nearest Neighbor) technique, and neural networks. The neural net method was shown to outperform the other methods in robustness and predictive accuracy. In addition, the explanation capability of the neural net was investigated. The contributions of the input variables to the change in the output variable were interpreted by analyzing the connection strengths of the neural net when the net stabilized. We conclude by discussing the use of neural nets in knowledge aggregation and decision support. C1 USN,POSTGRAD SCH,DEPT SYST MANAGEMENT,MONTEREY,CA 93943.

TI HYBRID MAGNETOSTRICTIVE/PIEZOELECTRIC TONPILZ TRANSDUCER SO FERROELECTRICS LA English DT Article AB A combined magnetostrictive/piezoelectric hybrid sonar tonpilz transducer which produces enhanced motion at one end and cancelled motion at the opposite end has been developed. The transducer combines the high strain magnetostrictive material Terfenol-D with that of Lead Zirconate Titanate (PZT-4) piezoelectric ceramic. The transducer has the ability to electrically self-tune and shows an improved effective coupling coefficient 25% greater than a conventional tonpilz type transducer. The in-water mechanical resonance and electrical self-tuning occur in the vicinity of 4.25 kHz, where a 15 dB front-to-back pressure ratio was obtained under a 12 element array loading condition. The high coupling coefficient and double resonant system makes this transducer attractive for wide bandwidth operation. With simple manipulation of the design parameters analytical results predict a vastly increased bandwidth of the transducer. An increase in bandwidth from the traditional tonpilz value of 20% to over 100% can be achieved. C1 [Butler, Stephen C.; Lindberg, Jan F.] USN, Undersea Warfare Ctr, New London, CT 06320 USA.

The portable, hand-held detector was developed to monitor vapors of volatile chlorinated compounds above waste oils to determine if they can be recycled or should be treated as hazardous materials. The unit is run on batteries or with an A/C adaptor and is rechargeable. Five different oils were spiked with four different chlorine containing compounds, The spiked samples were analyzed both with chemical kits and with the detector, Our results indicate that the detector should be useful for a fast qualitative analysis and limited semi-quantitative analysis of the volatile chlorinated contaminants of oil samples under field conditions.

To explore the possibility that increased reactive O-2 metabolite generation may result in oxidative modification of lipids and proteins, rats were exposed to five atmospheres (gauge pressure) of O-2 until development of an electroencephalographic seizure. Lipid peroxidation (as thiobarbituric acid-reactive substances) and protein oxidation (as 2,4-dinitrophenyl-hydrazones)were measured in five brain regions. Oxidized and reduced confined to the frontal cortex and hippocampus, while protein oxidation (in both cytoplasmic and membranous fractions) and increased oxidized glutathione was evident throughout the brain. These results support a role for formation of reactive O-2 metabolites from hyperbaric O-2 exposure and suggest that protein oxidation, especially in soluble proteins, may be one of the most sensitive measures.

A very important element of digital control to be taught is the use of microcontrollers as ''embedded'' elements in feedback control systems. A good simulation of a real microcontroller can be immensely helpful to demonstrate concepts and to give students some practical experience using embedded processors in a variety of applications. Finding no suitable embedded computer simulator for our undergraduate students, we proceeded to develop and use a Windows-based simulation of the PIC16C54/57/71/84 RISC microprocessor family. The program contains a program editor, an assembler, debugging tools, graphical representation for all registers, tools to present signals on device pins, and many other features that are all integrated together in a Windows environment. This paper describes the simulation and discusses our experiences while using the simulation over a period of two semesters in an introductory microcontroller class.

Critical to the process is the location and alignment of small holes, or vias, which allow electrical conduction between the different layers of the circuit board. Inspection of the vias continues to be carried out manually by most manufactures of these boards. This paper describes a Sr.Capstone project to automate the via inspection process and develop an automated via inspection station.

Most of these efforts, which strive for lower flux detection limits and more rapid follow-up, have been concentrated at optical wavelengths. However, many new results have also been obtained at radio, infrared, EUV, and X-ray energies. Recent deep quiescent surveys at optical and infrared wavelengths are reviewed along with efforts to correlate classes of astronomical objects with GRB localizations. New results on optical transients and how they might be related to the GRB phenomenon are also discussed. Detection efforts for VHE/UHE photons, UHE cosmic rays, and neutrinos and muons are reviewed along with the distance scales implied by these results. Finally, a brief overview of future projects and their possible impacts is presented. RP Vrba, FJ (reprint author), USN OBSERV,FLAGSTAFF STN,POB 1149,FLAGSTAFF,AZ 86002, USA.

For the high-latitude (b = -26 degrees) OT localization, we find a blue source with broad-band colors consistent with a QSO/AGN, which is consistent with our earlier work that found a QSO likely associated with OT050510. For the low-latitude OT (b = -1 degrees), we find a red star of about spectral class M. We are unable to provide evidence about whether these historical OT events are related to the nearby but much later GRB events.

Our goal is to present decision support information in a format that minimizes any mismatches between the cognitive characteristics of the human decision maker and the design and response characteristics of the decision support system. This includes two major thrusts. The first thrust involves the central hypothesis of the TADMUS program: presenting decision makers with decision support tools which parallel the cognitive strategies they already employ, thus reducing the number of decisionmaking errors. Hence, prototype display development has been based on decisionmaking models postulated by naturalistic decision-making theory, such as the recognition-primed decision model and explanation-based reasoning. The second thrust involves incorporating human-system interaction principles which are expected to reduce cognitive processing demands and thereby mitigate decision errors caused by cognitive overload, which have been documented through research and experimentation. Topics include a discussion of: (1) the theoretical background for the TADMUS program; (2) the decision support and human-system interaction principles incorporated to reduce the cognitive processing load on the decision maker (3) a brief description of the types of errors made by decision makers and interpretations of the cause of these errors based on the cognitive psychology literature; and (4) a description of the decision support system.

Although the path to validation of RANS computational software can be described, the hurdles to be overcome are significant. A study of available data by Longo & Stern (1995) identified serious deficiencies in all existing measurements that are potentially useful for validations. The Office of Naval Research (ONR) has identified a surface combatant geometry (DTMB Model 5415 Surface Combatant) for the purposes of validating computational ship hydrodynamics. The implemented strategy consists of five parts: downselection of software, dissemination of software and documentation, aggressive application, complementary computational ship hydrodynamics and towing tank investigations, and scaling. The underlying philosophy is that computational ship hydrodynamics is sufficiently advanced that the crucial development need has shifted towards expensive measurement validation for ship models, and that international exchange and discussion of new validation information is essential to meet the need.

The network is based on the Generalized lmmittance Converter (GIG) configuration, known for its excellent passive and active sensitivities. CMOS switches were used for elements relocation and are digitally controlled to select and realize different filter topologies. Switches were also used to control banks of binary-weighted capacitors that determine the filter center frequency, quality factor as well as its order. The bilinear transformation were utilized in the SC implementation of the filter resistive elements. Extra care was considered in the design procedure to minimize the effect of stray capacitors on the network transfer functions. The result was a general purpose digitally programmable multi-stage network that can equally compete with the best available stray insensitive filter. The design also inherit the low active and passive sensitivities the GIC enjoys. RP Michael, S (reprint author), USN,POSTGRAD SCH,DEPT ELECT & COMP ENGN,MONTEREY,CA 93943, USA.

This paper briefly discusses the step frequency radar and its associated signal processing, and it investigates this type of radar with the ambiguity function. The mathematical expression is derived for the ambiguity function of step frequency radar receiver and processor. The processor functions included are range gating, weighting, fill pulses, and inverse discrete Fourier transform (IDFT). Ambiguity diagrams are plotted for step frequency receiver processor and comparison is made with traditional constant frequency radar.

Here, we utilize these quantities to analyze sonar signals leading to detection and localization of underwater sources. The entropy of a process having a finite number of sample points is maximum when the received process consists of noise alone and decreases when a correlated signal is present. The mutual information is a measure of the amount of information that one random variable contains about another random variable. Here we present the results of analyses of active and passive sonar signals based on nonlinear techniques of entropy and mutual information, and compare them with results by traditional techniques.

Low noise is achieved because the transduction from a photocurrent to a voltage uses capacitive coupling rather than the use of a load resistor. The floating-gate photosensor has demonstrated a noise equivalent power of 10nW, a rise time of 50nS, and a dynamic range of 10(5):1. The detector is AC coupled and has a square-root compressing transfer function for large photosignals. RP Kub, FJ (reprint author), USN,RES LAB,CODE 6813,WASHINGTON,DC 20375, USA.

For signal detection applications, locally optimal nonlinearities are optimal as the signal strength gamma goes to zero, however, for non-zero values of gamma, the performance of Page's test may be improved by applying a subtractive bias. The bias that maximizes an asymptotic (i.e., as the average time between false alarm goes to infinity) performance measure for Page's test for a fixed signal strength is derived for a general detector nonlinearity. Additionally, the bias is derived to minimize the signal strength required to achieve a desired asymptotic performance. These two methods for choosing the bias are shown to be equivalent. The asymptotically optimal bias for the LLR nonlinearity is shown to be zero, which is consistent with the optimality of the LLR. Subject to a first order approximation, it is shown that the proposed asymptotically optimal bias is equivalent to an extension of the bias derived by Dyson [1] which approximately maximizes the relative efficiency between Page's test with the biased locally optimal nonlinearity and Page's test with the LLR nonlinearity. The use of the asymptotically optimal bias is illustrated through an example. RP Abraham, DA (reprint author), USN,SACLANT UNDERSEA RES CTR,MAIL CMR426,APO,AE 09613, USA.

This variability in the configuration of the sensor system poses a significant problem when tracking maneuvering targets because of the uncertainty in the target motion model, A Kalman filter is often employed to filter the position measurements for estimating the position, velocity, and acceleration of a target. When designing the Kalman filter, the process noise (acceleration) variance Q(k) is selected such that the 65 to 95% probability region contains the maximum acceleration level of the target. However, when targets maneuver, the acceleration changes in a deterministic manner Thus, the white noise assumption associated with the process noise is violated and the filter develops a bias in the state estimates during maneuvers. If a larger Q is chosen, the bias in the state estimates is less during a maneuver, but then Q poorly characterizes the target motion when the target is not maneuvering and the filter performance is far from optimal. Here, the problem of tracking maneuvering targets with multiple sensors is illustrated through an example involving target motion in a single coordinate in which it is shown that with two sensors one can have (under certain conditions that include perfect alignment of the sensors) worse track performance than a single sensor, The Interacting Multiple Model (IMAI) algorithm is applied to the illustrative example to demonstrate a potential solution to this problem of track filter performance.

The approach, which lends itself to a broad range of narrowband and wideband filtering applications, involves parallel connections of frequency-selective, unilateral network branches that contain both passive and active subcircuits. Highly selective filtering action derives from controlled interferences among branch signal components. Attributes of the new technique include unconditional circuit stability, tolerance for large passive-circuit-element losses, practicability of narrowband lumped-element configurations, graceful performance degradation with active element parameter changes, and the advantage of module-based procedures for design and implementation. The broad applicability of the new approach is illustrated with three experimental demonstration circuits that employ off-the-shelf MMIC amplifier chips. The circuits comprise a 10-GHz notch filter of one quarter percent bandwidth, a 10-GHz bandpass filter of two percent bandwidth, and a 7.5-GHz lowpass filter.

The steady-state and dynamic characteristics of each of these control methods are illustrated and compared for a selected inverter design, It is shown that the feedforward controller exhibits steady-state error and an undesirable overshoot of the output voltages during startup, The addition of a feedback loop eliminates the steady-state error and reduces the overshoot; however, the natural response is underdamped regardless of the choice of feedback gains, A decoupling feedback control strategy that eliminates the disadvantages of the feedforward and feedforward/feedback controllers is described, Using the decoupling feedback controller, it is possible to eliminate the steady-state error and place the closed-loop poles wherever desired, Moreover, if the closed-loop poles are selected appropriately, it Is possible to eliminate the overshoot of the output voltages during startup transients.

Such properties fall outside of the Alpern-Schneider safety/liveness domain, and hence, they are not subject to the Abadi-Lamport Composition Principle. This paper introduces a set of trace constructors called selective interleaving functions and shows that possibilistic information-flow properties are closure properties with respect to different classes of selective interleaving functions. This provides a uniform framework for analyzing these properties, allowing us to construct both a partial ordering for them and a theory of composition for them. We present a number of composition constructs, show the extent to which each preserves closure with respect to different classes of selective interleaving functions, and show that they are sufficient for forming the general hook-up construction. We see that although closure under a class of selective interleaving functions is generally preserved by product and cascading, it is not generally preserved by feedback, internal system composition constructs, or refinement. We examine the reason for this. RP McLean, J (reprint author), USN,RES LAB,CTR HIGH ASSURANCE COMP SYST,WASHINGTON,DC 20375, USA.

The implant activation varies widely (30 -> 100%) depending on, what energy level is assigned to the Si, the implantation and annealing temperatures, and the quality of the substrate. The usable maximum temperature for activation is limited by the severe decomposition of the GaN. After 1050 degrees C 15s RTA Ga liquid droplet formation has been observed by SEM. This decomposition changes the surface morphology but did not introduce measurable change in the electrical properties up to 1150 degrees C/120s RTA.

Substrates were polished off-axis 5.5 degrees +/- 0.5 degrees in the [100] direction prior to film deposition. Some of the diamond films developed tensile stress sufficiently large to result in cracking on {111} cleavage planes, while other films exhibited compressive stress. The strain and mosaic structure were measured with seven crystal x-ray diffraction. This characterization tool allowed the separation of misorientation effects from those of lattice parameter variation. Films exhibited smaller (similar to 88 ppm) and larger (similar to 27 ppm) perpendicular lattice parameters relative to the HPHT substrates. A cross-sectional approach for probing strain in diamond films with micro-Raman analysis was used to show stress distributions (similar to 100-300 MPa) through the thickness of the film.

The deposits were characterized by micro-Raman spectroscopy, x-ray diffraction, and atomic force and scanning electron microscopies. Above similar to 1600 degrees C preferential < 110 < growth directions were identified for the majority of the crystals. At intermediate deposition temperatures (1600-1700 degrees C) the dominant morphology consisted of yellow prismatic crystals heavily twinned along {111} and {11(1) over bar}. At substrate temperatures exceeding similar to 1750 degrees C hexagonally-shaped {111} oriented 3C-SiC platelets were formed with alternating {001}/{101} edges. The dependence of nucleation density, film morphology and film orientation on deposition conditions will be discussed with emphasis on the growth of high quality single crystals of 3C-SiC.

The motivation for the current-temperature measurements was to assess the thermal stability of the diamond emitters and gain some insight into a possible emission mechanism. Results from the current-temperature (I-T) measurements found that the field emission current appeared independent of temperature.

The majority of users of imaging spectrometer data are interested in studying surface properties. Therefore, atmospheric absorption and scattering effects must be removed from imaging spectrometer data, so that surface reflectance spectra can be derived. Previously, an operational atmosphere removal algorithm (ATREM), which used the 5S code for modeling the atmospheric scattering effects and the Malkmus narrow band model for modeling atmospheric gaseous transmittances, was specifically designed for deriving surface reflectances from spectral imaging data collected by the NASA JPL Airborne Visible/Infrared Imaging Spectrometer (AVIRIS). We have recently updated this algorithm by replacing the 5S code, which requires that the sensor be at the top of the atmosphere, with the 6S code, which accommodates sensors at any altitudes. The updated algorithm allows processing of imaging spectrometer data (with a spectral resolution of approximately 10 nm or coarser) acquired from low- and high- altitude aircraft platforms, and from satellite platforms. We are currently developing another algorithm that uses a line-by-line code to calculate atmospheric gaseous transmittances for processing imaging spectrometer data with spectral resolution between approximately 0.5 and 10 nm.

As part of HYDICE's first operational mission, one objective was to test the system performance over the dark homogeneous target provided by the clear deep waters of the lake. The high altitude and clear atmosphere makes Lake Tahoe a simpler test target than near-shore marine environments, where large aerosols complicate atmospheric correction and sediment runoff and high chlorophyll levels make interpretation of the data difficult. Calibrated data from both sensors was provided in physical units of radiance. The atmospheric radiative transfer code, MODTRAN, sensors was provided in physical units of radiance. The atmospheric radiative transfer code, MODTRAN, was used to remove the path radiance between the ground and sensor and the skylight reflected from the water surface. The resulting water-leaving radiance can be compared to measurements made at the lake surface with a hand-held spectrometer, and with values calculated from in-water properties using the HYDROLIGHT radiative transfer code. The agreement of the water-leaving radiance for the HYDICE data, the ground-truth spectral measurements, and the results of the radiative transfer code are excellent for wavelengths greater than 0.45 mu m. The AVIRIS flight took place more than an hour closer to noon, which makes the radiance measurements not directly comparable. Comparisons to radiative transfer output for this later time indicate that the AVIRIS data is strongly affected by sun giant. Because water-leaving radiance is dependent upon the characteristics of the water, it can be analyzed for some of those properties. Using the CZCS algorithm based on the water-leaving radiance at two wavelengths, the chlorophyll content of Lake Tahoe was computed from the HYDICE and ground-truth data. Resulting values are slightly higher than measurements made two weeks earlier from water samples, indicating a growth in the phytoplankton population which is very plausible given the interviewing atmospheric conditions. The success in determining water-leaving radiance and interpreting it for pigment concentration are very positive results for this early HYDICE flight. The interpretations made so far do not make use of the full spectral content of the data, so much room for advancement remains.

Advances in the field of molecular immunology during the past decade have provided an insight into the presentation of peptides by MHC class I molecules and their recognition by CD8+ T cells, These studies have provided a conceptual basis for the development of efficacious parasitic and viral vaccines, By a combination of immunochemical and cellular immunologic analyses based on specific peptide binding motifs, a subunit malaria vaccine that includes CD8+ T cell epitopes restricted by the most common class I HLA alleles, including HLA-A2, can now be constructed.

The control design uses sliding-mode method and therefore has the advantages of order reduction, disturbance rejection, insensitivity to parameter variation and simplicity of implementation. The design is based on the original nonlinear dynamic equations of the rotor and global stability of the closed loop system is guaranteed. The proposed approach integrates both adaptive and robust control where the adaptive design is used to cancel out the gravitational force and the force due to rotor mass imbalance and the robust design is used to compensate for other disturbances and improve the transient performance. Numerical simulations are provided to demonstrate the efficacy of the proposed control. RP Song, GB (reprint author), USN,POSTGRAD SCH,DEPT MECH ENGN,MONTEREY,CA 93943, USA.

The Real-Time STructural Response And Information Network (RTSTRAIN) will monitor the response of the hull girder and secondary structure to the seaway. This information will be continuously processed in real time and used to provide warnings and recommendations to the bridge and/or engineering crews concerning structural integrity, suggested and required maintenance, as well as suggested course and speed to minimize loading on the hull girder. The system will provide the means for safer operation, and at the same time, minimize the possibility of structural damage and reduce structural fatigue damage accumulation. Data will also be analyzed and stored for the purpose of improving current design and analysis methodologies. The system will incorporate commercial-off-the-shelf (COTS) hardware and software where possible, to minimize cost, increase compatibility and availability, and provide modularity and upgradability. A distributed data acquisition and sensor system, using local signal conditioning in conjunction with a digital communication technology, will greatly reduce installation costs compared to conventional analog systems, and provide for a reliable and flexible system. Initial system development has begun, demonstrating the capability to remotely acquire data from several locations, transmitting the data over a conventional network, and storing the data at a central acquisition computer. The details and specifications of RTSTRAIN will be outlined and discussed, highlighting the lifecycle extension, safety and preventative maintenance benefits offered by the system.

This replacement, ''FNET'', is a vast improvement over DMS both in performance and in lower cost. However, the interface modules have not changed, and the Navy will be left a with sixteen bit architecture that is not used commercially. This means that FNET will leave the Navy with an expensive, government owned design that will probably not be upgraded in the future unless the Navy pays for all the development costs. Fortunately, there are parts of FNET that use standard interfaces, used commercially and supported by other architectures. One such architecture that supports the protocol used to interface all of the nodes on FNET is VME. It may be possible to replace every FNET node with VME based nodes which should prove to be less expensive, widely available commercially, and upgradable. If the Navy invests now in a COTS network to interface with or replace FNET, it may have many more options for a less expensive COTS shipboard communication system in the 21st Century.

Automated versions of vintage psychomotor tests (developed in the 1930s and 1940s) seem to be as predictive of military pilot/aviator performance today as in the past. The psychomotor tests receiving the most attention today are the Complex Coordination and Two-Hand Coordination tests originally developed by Mashburn and colleges before World War II (Mashburn, 1934). These tests were significant predictors of Air Force and Navy pass-fail criteria in the past, and automated versions are similarly predictive today. The U.S. Army and Air Force are now using a combination of paper-and-pencil and automated psychomotor-cognitive tests for initial selection (Air Force) or helicopter assignment (Army). It appears that the Navy is considering the use of automated cognitive and psychomotor tests in a selection battery of the future. C1 UNIV CENT FLORIDA,CTR APPL HUMAN FACTORS AVIAT,ORLANDO,FL 32816.

At 0116 hours, participants were administered either a 5 mg/70 kg oral dose of d-methamphetamine (n = 10), 10 mg/70 kg d-methamphetamine (n = 10), or a placebo (n = 10) using standard double-blind procedures. Performance on all measures degraded markedly during the night in the placebo group. Both the 5- and 10-mg methamphetamines treatment reversed an initial decline in d', and reversed increases in nonresponses (lapses) and tracking error within approximately 3 hr of administration. No evidence that amphetamine treatment increased impulsive responding (fast guesses) was observed. The magnitude of the performance effects of the methamphetamine treatments was similar at 3 hr postadministration. However, the effects of the 5-mg dose were shorter-lived, disappearing by the last testing session (6.5 hr postadministration), whereas effects of the 10-mg dose tended to remain throughout testing. Both amphetamine treatments decreased subjective sleepiness during the night and tended to increase subjective sleep latencies during a post-testing sleep period.

The aim of the work is to achieve synchronization-free parallel implementations by the introduction and use of load balancing and processor routing schemes. Two representative and popular finite difference techniques, the implicit Beam and Warming and the explicit MacCormack techniques, are parallelized and tested on a 20-processor computer. Several parallel implementations of increasing complexity are investigated in the context of the simple heat and the more computationally intensive curvilinear grid mapping equations. In attaining near-theoretical speedups, the need for processor synchronization has to be eliminated completely. To achieve a synchronization-free parallel implementation, three stratagems are introduced and evaluated. First, each finite difference technique is split into multiple computational phases. Second, the computational loads of the working processors are carefully balanced. Finally, efficient processor routing is applied in order to avoid creating regions of processor interference. The result of combining these three novel but intuitive approaches is the gain of a general parallelization philosophy that should be applicable to finite difference and volume techniques in general. Speedup values obtained for the two specific finite difference techniques chosen for this work are significant with the largest ones resulting from more complex equations, larger size grids, and more stringent convergence criteria.

Lilly's expression was tested for determining Smagorinsky's coefficient in the model without ad hoc measures such as ensemble-averaging or filtering, However, zero cut-off of negative total viscosity was necessary to maintain stable solutions, A discretized filter function is derived for the test filter, Good qualitative and quantitative agreement with published experimental data was obtained indicating that the dynamic model performed quite well, The cavity flow at Reynolds number of 10(4) is transitional, The highest turbulent production levels not only occurred within the downstream eddy region of the cavity, but also along the upper half of the downstream wall.

Forced convection Nusselt numbers show the influences of Dean vortex pairs and other transitional phenomena. In particular, Nusselt numbers on the concave surface become higher than ones measured at the same streamwise location on the convex surface just after the start of curvature. Important Nusselt number increases also occur due to the twisting secondary instability as the Dean number increases from 150 to 200. C1 USN,POSTGRAD SCH,DEPT MECH ENGN,MONTEREY,CA 93943.

This article reports an experiment intended to show that real-world wayfinding and environmental design principles are effective in designing virtual worlds that support skilled wayfinding behavior. The study measures participant performance on a complex searching task in a number of virtual worlds with differing environmental cues. The worlds are augmented with either a radial grid, a map, or both a grid and a map. The control condition provided no additional navigational cues. The results showed that navigational performance was superior under both map treatments as compared to the control and grid conditions. The grid was, however, shown to provide superior directional information as compared to the other conditions. The control condition provided the worst performance, with participants often becoming disoriented and experiencing extreme difficulty completing the tasks.

The structure, composition and thickness have been measured using XRD and RES. The dielectric properties of the film have been measured at 1 MHz utilizing an LCR meter, The results indicate that the films are single phase and (001) oriented, However, film composition, thickness and dielectric properties are not uniform along the radius of the film. The results indicate that the composition nonuniformity is due to off-axis deposition, and correlates with changes in the dielectric properties.

Note the term ''triode'', a term and concept which dominated transistor papers for many years. The transition from vacuum devices to solid-state took a long time; the first devices were fragile, not reproducible, and they failed easily and frequently. Furthermore, the semiconducting material and processing technology had to be invented and developed. After much hard work and much funding, those first transistor ideas were superseded by a large variety of different structures, made from different semiconductor material systems; However, the solid-state industry blossomed only after the inventions of planar processing and the integrated circuit.

Our measurements show that arc damage is reduced by placing resistance in series with FEAs, but appears to remain the dominant failure mechanism. Once ignited, an arc can potentially dissipate most of the energy stored in the charged capacitance of the FEA, regardless of how well protected the FEA is. Simple calculations show that the energy stored in a state-of-the-art low capacitance FEA is more than enough to melt sufficient material to ruin a tip or form a short between a tip and the gate. In order to produce more uniform emission for display applications, resistances are typically incorporated into the array in series with each tip. Arc damage has been suppressed in these FEAs, allowing them to be used in poor vacuums. The resistance produces a significant RC time constant, limiting the frequency at which the gate-tip voltage can be modulated. However, the value of the resistance appropriate for display applications may be much larger than required to reduce arc damage. Similarly, the capacitance in series with the resistor can be made very small. Thus it may be possible to use integrated resistance to limit arc damage while maintaining RF modulation compatibility.

The vibratory component of four rotor system loads is examined; main rotor pushrod, rotor blade normal bending, lag damper, and main rotor shaft bending load. Univariate relationships between these loads and fixed system parameters are examined and basic trends are highlighted, Multivariate approaches including multiple linear regression and artificial neural network analyses are utilized to create load prediction models. Fixed system parameters form the basis of the models and include pilot control positions and aircraft state parameters. Generally, the loads can he predicted quite well during steady level night, as well as moderate and high-g flight where fatigue damage is most likely to occur. Low speed and hovering night and flight conditions with low engine torque are the most difficult night conditions for accurate load prediction. Significant parameters in the regression and neural network models are identified and several night regimes are defined that can be used to improve load prediction accuracy.

Film growth occurs by a Stranski-Krastanov process with reaction at the immediate interface leading to metallic Ga. Annealing at >800 degrees C leads to release of N, which reacts with Al to form a (1X1)-ordered layer of AlN, possibly alloyed with a small. amount of Ga. The AIN layer has been characterized using the various spectroscopies, and the work function, band bending, and electron affinity of GaN and of the AlN overlayer have been obtained. The Al/GaN Schottky barrier height has been measured and compared with previous results for Ni/GaN. RP Bermudez, VM (reprint author), USN,RES LAB,DIV ELECTR SCI & TECHNOL,WASHINGTON,DC 20375, USA.

Our particular focus is on locally interconnected synchronous networks in which the numerical discreteness of a computation is represented directly by the quantization of electron charge, i.e., electrons represent bits. To highlight our emphasis on circuits and architectural issues, and on performing locally interconnected computation rather than traditional logic as has been the interest heretofore (single-electron logic), we refer to our networks as single-electron digital circuits (SEDCs). in addition to being single-electron and locally interconnected, the SEDCs we propose have a regular ''cellular'' structure with occupancy-independent biasings and with electron-electron interactions carefully controlled. The chief virtue of SEDCs is their scalability, both as devices (because of their Coulomb blockade basis) and as circuits (because of their local interconnectivity), perhaps even to molecular dimensions. We illustrate our approach with a number of new ''device'' and network designs based on electron-pump-like structures and mostly directed at performing lattice-gas simulation. For this application we effectively create an electron gas within a SEDC which precisely mimics the lattice gas. Finally, we have validated our designs using numerical simulation and expect that at least some of them should be realizable in current technology. However, their promise of enormous levels of integration and performance should be tempered with a clear awareness of the many obstacles associated with fabrication and economics which must be overcome if they are ever to be the foundation for a practical computer technology.

Previous experimental studies have qualitatively linked the formation of kink bands to the presence of fabrication defects, such as fiber misalignment. These local singular stress regions serve as the primary trigger mechanism for kink band propagation in 0 degrees-plies. The present analysis also explains the previous test results relating to propagation of failure from a notch in a unidirectional composite under compression. Furthermore, the present investigation is the first to quantify, in the context of LEFM (linear elastic fracture mechanics), the sensitivity of these composites to inherent local flaws, such as fiber misalignments, and also shows the inadequacy of the conventional elastic micro-buckling type of analysis to fully explain the experimental results. Although because of the assumed isotropy of the fiber and matrix materials, the present study is primarily suited to glass fiber reinforced composites, the conclusions drawn here are general enough to apply to carbon fiber reinforced composites as well. Numerical results presented include the effects of fiber included wedge angle, and the ratios of fiber-matrix shear moduli and Poisson's ratios on the strengths of the mode I and mode II singularities. Of special practical interest is the present LEFM type of analysis applied to quantitatively investigate the inherent flaw sensitivity of two E-glass/epoxy composites experimentally investigated earlier. Compression fracture type of failure of these composites can be fully explained and quantified by the present two-dimensional LEFM-based method, which is beyond the scope of one-dimensional micro-buckling approach.

The environs of the typical fiber in the random pattern have a higher fiber areal density nearer to the fiber than farther away. These differences increase with volume fraction. The RDFs for random patterns show good agreement with theory. The RDFs for Nicalon/zirconia titanate composites appear similar to the random case, but also display an angular dependence on near-neighbor distribution. The proximity of near-neighbors has important ramifications for modeling the micromechanics of tow-based fiber composite mateials.

The method consists mostly of algebraic manipulations and is very efficient on vector computers. The method is applied to the solution of the three-body Schrodinger equation. Besides giving, in contrast to variational methods, uniformly precise expectation values of operators including the Hamiltonian, the method allows one to study the analytic structure of the wave function. Applications to the He atom, the muonic helium atom, and the mu dt molecular ion are presented. No extended precision intermediate calculations are required. (C) 1996 Academic Press, Inc.

The coupling of a long hydrocarbon chain to a ring nitrogen decreased the general ability of the cyclam ring to complex with metal ions. The greatest effect appeared to be for Cu(II) decreasing from a pK of 27 for cyclam to about 17. The titrations were fitted by HYPERQUAD and the concentrations of the intermediate complexes obtained as a function of pH. Metal-ligand complexes LMH(2)(4+), LMH(2+) and LM(2+) can co-exist through a wide pH range. We have also calculated a composite metal-binding constant, K', to reflect more accurately the overall ability of these ligands to bind a metal at any particular pH. K', which is 14.6 for (hexadecyl cyclam)-Cu(II), is constructed from the concentrations of all the metal-chelated species at pH = 7. Generally, K' is much lower than K.

Advertising may be one such variable. By shifting the demand curve inward or outward between rate hearings, the firm may increase its earnings above the allowed level. Here, a simple discrete-time optimal-control model is proposed to examine the dynamic implications of advertising by the regulated firm. Our results indicate that, in the long run, the combined effect of regulation and advertising leads to a steady-state equilibrium that is closer to the minimum point on the firm's long-run average-cost curve than the original output level. Thus, an invisible-hand property is established that pushes the regulated firm to shift its demand curve toward the minimum point on its long-run average-cost curve in the presence of regulation. As a result, the well-known allocative inefficiency created by rate-of-return regulation (P not equal MC), on which so much has been written over the past 100 years, is reduced (and, under certain conditions, eliminated) if the regulated firm is allowed to advertise.

The C and Si co-implantations were used as an attempt to improve Al acceptor activation in SiC. The implanted material was annealed at 1500, 1600, and 1650 degrees C for 45 min. The Al implants are thermally stable at all annealing temperatures and Rutherford backscattering via channeling spectra indicated good lattice quality in the annealed Al-implanted material. A net hole concentration of 8 x 10(18) cm(-3) was measured at room temperature in the layers implanted with Al and annealed at 1600 degrees C. The C or Si co-implantations did not yield improvement in Al acceptor activation. The co-implants resulted in a relatively poor crystal quality due to more lattice damage compared to Al implantation alone. The out-diffusion of Al at the surface is more for 5Si co-implantation compared to Al implant alone, where 5Si means a Si/Al dose ratio of 5. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

As the aurora penetrates to lower altitudes (less than 100 km) the role of quenching by atomic oxygen becomes less important and processes involving N-2 collisions begin to play a more prominent part. We are developing a model which will yield steady state vibrational level populations for both the singlet and triplet valence states of N-2. The model currently provides results for the seven low-lying N-2 triplet states (A(3) Sigma(u)(+), B-3 Pi(g), W-3 Delta(u), B'(3) Sigma(u)-, C-3 Pi(u), D-3 Sigma(u)(+), and E(3) Sigma(g)(+)). These states are responsible for auroral emissions from the UV (Vegard-Kaplan (VK), second positive (2PG)) through the visible to the infrared (first positive (1PG), infrared afterglow (IRA), Wu-Benesch (WB)). We have included two additional collisional processes in the current model which were not treated previously. These are the intersystem collisional transfer of excitation (ICT) between the B state and the A, W, and B' states and vibrational redistribution within the A state vibrational manifold, both due to collisions with ground state N-2. The present work compares our current model results with those of a previous model as well as ground, airborne, and rocket observations. The comparison between N-2(A) (VK) and N-2(B) (1PG) vibrational level populations predicted by our model and a number of auroral observations indicate that the current model achieves a significant improvement in the fit between calculation and observation. In addition, the current model predicts a shift in the band intensity distribution of the 1PG Delta nu = 3 sequence from the infrared into the visible red at the lower altitudes (less than 90 km) as well as an overall enhancement in the entire 1PG system. Consequently, this provides a possible explanation of a dominate feature of type b aurora, the auroral red lower border. C1 UNIV MARYLAND,INST PHYS SCI & TECHNOL,COLLEGE PK,MD 20742.

This is the first direct demonstration of a tandem repeat associated with heteroplasmy in the control region of a bird. A novel model for repeat duplication, which involves an inverted repeat located adjacent to the tandemly repeated sequence, is presented. Individuals with three repeats are absent from the endangered population of San Clemente loggerhead shrike in southern California, suggesting that the island endemic has a small effective population size and that there is insignificant gene flow from the adjacent mainland.

Harmonic distortion measurements were made with two single-frequency offset-phased-locked Nd:YAG lasers which provide a source dynamic range greater than 130 dB and a 1 MHz-50 GHz frequency range. Carrier transport is analytically described by three coupled nonlinear differential equations, Poisson's equation and the hole and electron continuity equations. These equations are numerically solved to investigate and isolate the various nonlinear mechanisms. The numerical solution incorporates diffusion since our treatment includes carrier generation in the highly doped p-region of the device. This p-region absorption and carrier-dependent carrier velocities associated with a perturbed electric field (due to space-charge and loading effects) are shown to dominate photodetector nonlinear behavior. The numerical model was extended to predict that maximum photodetector currents of 100 mA should be possible in 20 GHz bandwidth devices before a sharp increase in nonlinear output occurs. In addition, second harmonic distortion improvements of 40-60 dB may be possible if photodetectors can be fabricated with strictly-depleted absorbing regions.

We describe a clinical sign found in significant Lisfranc injuries that consists of a mid-foot ecchymotic area on the plantar aspect. This implies the potential for significant injury to the plantar tarsometatarsal ligaments. We call this the plantar ecchymosis sign. Patients with this injury and sign should be aggressively evaluated, with early consideration for stress radiographs and ORIF if indicated, as the prognosis of the undertreated Lisfranc injury is poor.

Logarithmic and exponential fits are considered to define early and late bursts, respectively, while linear fit describes loss at a constant rate. In a recently published study, the stepwise approach was applied to 6,935 sites in patients with established periodontitis and, of 581 loss detections, 195 (33.6%) were linear, 224 (38.6%) logarithmic, and 162 (27.9%) exponential. However, curvilinear patterns may occur by chance and regression algorithms that can fit such curvature may have an advantage unrelated to the true mchanism(s) of periodontal destruction. To investigate the implications of this possibility, proportions of linear, logarithmic, and exponential fit were estimated by simulation under four different conditions. These conditions incorporated random or random plus linear change, but no nonlinear effects. The relative proportions of model fits described in the published study were approximated in all of these conditions. It would appear that the observed proportions are ubiquitous to the modelling approach itself, and do not constitute evidence of a causal nonlinear biological mechanism. The stepwise approach may be useful for detecting change but relevance to causal processes seems problematic.

Hydrates ''cement'' sediments and impart considerable mechanical strength; they fill porosity and restrict permeability. Both biogenic and thermogenic methane have been recovered from hydrates. Hydrates occur in permafrost regions (including continental shelves), and are stable in ocean-floor sediments below water depths of about 400 m in the ''Hydrate Stability Zone '' (HSZ). This is a surface-parallel zone of thermodynamic equilibrium that extends down from the sediment surface to a depth determined by temperature, pressure and local heat flow. Methane and water are stable below the HSZ. Although the economic recovery of hydrates has taken place in Arctic regions,oceanic hydrates offer far greater potential as an energy resource. A variety of traps for methane gas can be formed by oceanic hydrates. In addition to the gas within the hydrates themselves, simple gas traps in closures beneath the HSZ in the vicinity of bathymetric highs, and complex traps involving both hydrate and structural/stratigraphic components, have been observed. It has been estimated that at least twice as much combustible carbon occurs associated with methane hydrates as in all other fossil fuels on Earth. The evaluation of methane in, and associated with, oceanic hydrates therefore constitutes a major energy exploration frontier. C1 USN,RES LAB,WASHINGTON,DC 20375.

It was found that the oxidation carried out using a gas-fed electrode was shifted 100-150 mV more cathodic than the electrolyte-fed electrode. A similar set of experiments was carried out using hydrophobic gas-diffusion electrodes and similar results were obtained. These results suggest that the mechanism of the methanol oxidation reaction depends on the nature of the surroundings and the orientation of the methanol with respect to the electrode surface. In the electrolyte-fed configuration the methanol will be in a hydrogen-bonded water cluster allowing the carbon end of the molecule to more readily approach the catalyst surface. While in the gas-fed configuration the methanol will interact with the water or oxidic surface through the hydroxyl end of the molecule. Clearly, these two possible mechanisms will lead to different products and one may enhance the rate of the direct oxidation of methanol as observed in this work.

The calculations reveal that the apparent unsteadiness of the type IV interaction is related to the formation and shedding of shear layers within the shock layer and acoustical feedback between the distorted bow shock and the body, A Fourier analysis of the flowfield indicates that this shedding frequency is the same frequency associated with the motion of the supersonic jet, The effects of shock impingement angle and shock strength on the location and magnitude of the peak pressure are also studied and it is shown that changes in the impinging shock angle can strongly affect the peak surface pressure and the supersonic jet position. Further examination of the unsteady behavior of the interaction reveals that a small change in the impinging shock angle can change the flowfield from steady to unsteady.

Notable research is highlighted regarding (1) wear of ceramics and opposing enamel, (2) polishability of porcelains, (3) influence of firing history on the thermal expansion of porcelains for metal ceramics, (4) machining and CAD/CAM as fabrication methods for clinical restorations, (5) fit of ceramic restorations, (6) clinical failure mechanisms of all-ceramic prostheses, (7) chemical and thermal strengthening of dental ceramics, (8) intraoral porcelain repair, and (9) criteria for selection of the various ceramics available. It is found that strong scientific and collaborative foundations exist for the continued understanding and improvement of dental ceramic systems.

The governing equations of motion of the coupled vehicle-moving-mass two-body system, which form the basis of the study, are presented and discussed. An analysis of these equations reveals that dynamic and aerodynamic cross-coupling is produced by the operation of this control system; however, some vehicle design techniques are employed to mitigate these effects. The mass effectiveness parameter, obtained through linearization of the moment equation, is shown to be the key system design parameter. The design of an optimal linear roll autopilot using modern state-space methods is presented in detail, along with an optimal-gain-vector scheduling function. A nonlinear seven-degree of freedom simulation of a typical mission profile trajectory demonstrates the ability of the linear autopilot to effectively control the vehicle's roll attitude and trajectory. Dynamic, aerodynamic, and inertial cross coupling do not appear to significantly degrade the control system's response. C1 UNIV MARYLAND,DEPT AEROSP ENGN,COLLEGE PK,MD 20742.

Twenty-nine patients referred to the NCI after exploration and determination of unresectability elsewhere were considered to have localized disease after a metastatic work-up. These patients were then entered onto NCI adjuvant therapy protocols and taken to exploratory laparotomy. Intraoperatively, patients underwent complete resection if possible; otherwise varying palliative surgical procedures were performed. Of the 29 patients, 16 underwent complete resection of their disease, and 13 were unresectable. Two patients suffered postoperative mortality. Disease-specific survival of the resected patients was significantly better than that of the unresectable patients (P < 0.01). The two long-term survivors (53 and >109 months) underwent definitive surgery after a palliative procedure elsewhere. Complete resection of pancreatic carcinoma contributes to increased survival. The intraoperative definition of unresectability in pancreatic cancer varies with the degree of pancreatitis present, the surgical expertise of the surgeon, and the available ancillary services. Given the extremely grave prognosis of patients with unresectable pancreatic carcinoma, locally unresectable patients without peritoneal seeding or distant metastases at exploration should be considered for referral for protocol therapy to centers where expertise in radical surgery for pancreatic cancer exists.

The shell's surface is first discretized into a number of small patches. The local geometry of each patch is then approximated in a parametric form using bi-cubic spline functions. A local curvilinear coordinate frame is defined on each patch. The ray trajectories and ray-tube areas are obtained by solving a set of ordinary differential equations, the ray and transport equations, within each patch. Several numerical tests of the accuracy and efficiency of the scheme were carried out on spherical and ellipsoidal elastic shells: The numerical results for the spherical shell agree well with analytical solutions. The ray trajectories and the ray-tube areas over an ellipsoidal shell with three distinct semiaxes clearly illustrate the inhomogeneous and anisotropic effects due to the variable curvature on the shell's surface. It is also observed numerically that the magnitude of the ray-tube area along a ray is directly correlated with the stability of its trajectory. (C) 1996 Acoustical Society of America.

Distortions by the environment effectively add three degrees of freedom (dimensions) to the signal. The dimension required to reconstruct and analyze the received data is five in contrast to a pure tonal or sine wave that only requires two dimensions. The data are examined with a chaotic data analysis toolkit that includes determination of degrees of freedom using local and global false-nearest-neighbor statistics, average mutual information, correlation dimension, and local Lyapunov exponents. These results are important for the development of methods for correction of propagation distortions and nonlinear noise reduction algorithms. Application of this knowledge should lead to improvements in the detection and classification of underwater signals. (C) 1996 Acoustical Society of America.

The existence of features as small as 0.5-mm equivalent spherical radius has now been confirmed by x-ray computed tomography of cores taken and scanned at in sial pressures. The interaction of an acoustic pulse from the acoustic sediment classification system (ASCS) with this type of gassy sediment was modeled and the results are presented here. The bubble scattering response model includes both the effects of nonspherical bubbles and of sediment resistance to shear deformation (as expressed by the dynamic shear modulus). Model predictions made using the observed gas bubble distribution agree with normal incidence ASCS data, exhibiting extended returns (i.e., greater than the source pulse length) from the seafloor bubble layers as well as high attenuation within the bubble layers. Spectrograms of ASCS and modeled return pulses were also similar. These results suggest that the acoustic return characteristics of the near surface sediments of Eckernfoerde Bay are dominated by scattering from a distribution of gas bubbles with depth.

The model, which uses a mathematical formalism based upon the harmonic solution of sets of coupled differential equations, allows a verified swimbladder scattering ''kernel'' for the individual fish to be incorporated. It includes all orders of multiple scattering interactions between fish, and calculates the aggregate scattering field by coherent summation. Application to simulated ensembles of closely spaced fish indicates significant deviations from incoherent scattering returns. Peak target strength reductions, and shifts in the resonance frequency, appear due to multiple scattering. The target strength also varies strongly with frequency as a result of interference effects. When applied to widely dispersed ensembles, the model reproduces the results of incoherent scattering. For larger ensembles, at greater depth, the model predicts sharply reduced target strength values around the main resonance. The ensemble effects of a school on the scattering of any single individual show more fluctuations as the school size increases. By reducing the viscous damping in the scattering kernel, the model can also describe scattering from small bubble clouds. The model has been applied successfully to fit experimental broadband low-frequency scattering data from schooling fish. RP Feuillade, C (reprint author), USN,RES LAB,BAY ST LOUIS,MS 39529, USA.

The model takes into account the discrete space-time structure of the noise sources and thus differs from models based on the continuous source sheet assumption. This is done using a stochastic model to specify the locations, occurrence times, and radiated noise waveforms for the individual breaking waves and then computing the noise field as the superposition of the noise contributions from those breaking waves. The angle-time-frequency resolution of the noise field is obtained by applying a time-frequency resolution algorithm to the output of a beamformer as a function of the steering angle. To describe the properties of the 3-D noise resolution, we assume a vertical array in a shallow-water acoustic environment and use recently obtained experimental estimates of the acoustic coverage and the source level and waveform-duration probability densities to determine the breaking wave source model parameters. The examples presented indicate that the breaking wave noise is largely confined to two angular sectors, the high-angle sector looking toward the ocean surface and the sector containing the discrete mode propagation energy. The high-angle noise exhibits a large temporal variability, characterized by a small number of large broadband bursts, and is only weakly dependent on the acoustic environment. On the other hand, the discrete mode noise shows less temporal variability, characterized by a larger number of smaller broadband bursts, and is strongly dependent on the acoustic environment. Finally, the angle-frequency structure of the low-level noise in the downward-looking direction represents an example of imaging the bottom with surface-generated ambient noise and suggests that ambient noise measurements might be used to estimate sediment thickness.

A simple expression is obtained for the damping induced in the large structure indicating that the damping depends primarily on the total effective mass of substructures resonating within a band centered at the frequency pf vibration, and is relatively independent of the damping factors of the individual substructures. The application of this simple expression for induced damping is illustrated by calculating the damping induced by substructures attached to an axially vibrating rod and to a flexurally vibrating beam. For the latter case, the calculated damping factors are compared with measured values. RP Strasberg, M (reprint author), NSWC,BETHESDA,MD 20084, USA.

Samples implanted with the oxygen ion beam in a channeling direction of the Si wafer contain more defects of both types than those prepared in an off-channel mode; thus, a correlation between excess silicon in the oxide forming Si clusters (amphoteric photosensitive defects) and the density of conducting defects may exist. We suggest that;interstitial Si atoms generated during the implantation/anneal process form filaments in structural channels in the BOX. However, the density of conducting defects may be influenced by other factors, such as contamination and/or the extent of the localization (lateral inhomogeneity) of the trapping defects. The defects in the BOX are distributed in a laterally inhomogeneous manner. This may result in varying density of conducting defects for the same integrated density of amphoteric defects. The observation of defects in the top Si layer and their correlation with conducting defects in the BOX indicate the possible involvement of some contaminant in the formation of conducting channels in the BOX.

Tests were performed on UHV cleaned SiC pins and Mo flats during or after exposure to SO2, O-2, or H2S gas al pressures around 40 Pa. XPS identified the gas reaction layers on Mo to be chemisorbed MoS2 and/or MoO2 phases less than 1 nm thick. AES of Mo wear tracks showed tribochemical films similar in composition to, but thicker than, the reaction layers. AES of SIC wear scars in all three gases indicated tribochemical films containing Si oxide and/or Si sulfide and possibly graphite. In addition, transfer films of Mo oxysulfide and Mo oxide were found in SO2 and O-2 tests, respectively, but no transfer films were detected in H2S tests. Thermochemical calculations of stable reaction products of the gas-solid reactions were in good agreement with the phases inferred from XPS and AES. An explanation for the agreement between thermochemical predictions and tribochemical results is given. (C) 1996 American Vacuum Society.

XPS measurements showed barium atoms to have two different chemical states at the BaF2/GaAs interface. The relative abundance of these two states was also determined by XPS. The number of barium atoms in each state was found by normalizing integrated XPS peak intensities to HIBS measurements of the total number of barium atoms on the surface. The results were used to formulate a model of a two-stage deposition mechanism whereby BaF2 first reacts with gallium at the surface and dissociates, releasing gaseous GaF. This reaction is apparently self-limiting, resulting in a barium ''template'' layer that enables subsequent BaF2 molecules to form an epitaxial (100)-oriented film.

One method for this determination proposed by Ebel et al. [J. Electron. Spectrosc. 34, 313 (1984)] for use in x-ray photoelectron spectroscopy determines the film thickness based on the area ratio of the C(1s) photoelectron and carbon (KVV) Auger peaks. The Ebel model has been evaluated in this work through the use of self-assembled monolayers (SAMs). The SAM approach permits the comparison of film thicknesses determined by the model with the known thickness of the controlled monolayers. Data from the SAMs consistently fell below the curve predicted by the model. Discussions of potential sources for error are presented with respect to photoelectron attenuation models. Examination of these potential sources, however, could not identify a source of sufficient magnitude to account for the difference between predicted and actual results. It is suggested that the error is due to an incorrect assumption with respect to the normalization factor used in the model. Additional excitation of the C(KVV) due to the large number of energetic photoelectrons originating from the substrate is suggested as the cause for the discrepancy between prediction and experiment. Experimental evidence supporting this assertion, and possible methods of correction are offered. (C) 1996 American Vacuum Society. C1 USN,CTR SURFACE WARFARE,SILVER SPRING,MD 20903.

In wavenumber-frequency space, this mixing manifests itself in the formation of hybrid modes, for example, mixtures of part shear and part flexural vibration. The mixing is strongest when the phase speeds of the different wave types coincide find so reflect the dispersion curves of the flexural Bloch wavenumber. The dispersion curves may be significantly altered by mixing effects, and even for weak wave mixing the polarization of the fast waves can be changed significantly. This effect greatly alters the coupling of the fast waves to an external fluid. RP Photiadis, DM (reprint author), USN,RES LAB,WASHINGTON,DC 20375, USA.

In localized vibration control, the controller attempts to stabilize one or more localized areas on the structure rather than attempting to stabilize the entire structure. The relative performance levels of different control strategies are evaluated by examining a frequency-dependent disturbance rejection property. A flat plate supported by two box girders is used as an example realistic structure. Plant dynamics from a finite-element model are used to draw general conclusions regarding the mechanisms by which localized vibration control is exerted.

Yet, there are no officially approved AIDS safety programs designed to protect medical health care personnel in the operating room. A sequential safety program is proposed beginning with the following steps: 1) evaluation and staging of the patient and associated complications; 2) protection of the major surgical and laser instruments; 3) use of an efficient evacuator system to avoid plumes of laser fragments from polluting the operating room environment; 4) protection of the operating room staff with special eye protection including helmets and shields, fluid-soak-resistant fabrics for garments, double surgical gloves, and special orderly trays with safety holders for syringes, needles, sharp instruments, and suture holders; 5) reporting and treatment of accidents, such as needlestick puncture wounds, that require immediate attention and an infectious disease consultation; 6) postoperative care, which includes providing medical health care personnel protection from bloody bandages, needles, and the infectious patient; and 7) and finally, the washing and sterilizing of contaminated instruments by medical health care personnel using face shields and masks, gloves, and protective fabrics for garments. Continued experience with this proposed safety program will determine its future value for AIDS surgical patients and for all health care workers.

Study Design/Materials and Methods: SINc was dissolved in canola oil by heating, emulsified with Tween-80, and given by ear vein. Pharmacokinetics were studied in frozen sections by fluorescence microscopy using a CCD camera-based, low light detection system with digital image processing at 1 hr and 24 hr (12 rabbits, 24 eyes total). A Ti:Sapphire laser delivered light at 770 nm by contact fiberoptic (1,000 mu m; 80 mW/cm(2);20,40 and 80 J/cm(2)). Controls (5 rabbits), received laser light at 770 nm without SINc. For comparison, eyes received continuous wave Nd:YAG laser by fiberoptic contact (0.8-1.2 J). Results: Localization studies showed intravascular distribution shifting to a ciliary body distribution at 24 hr, PDT at 1 hr and 24 hr postinjection showed a more selective destruction of the ciliary body at 24 hr. Ciliary processes treated at 24 hr showed infarction and marked edema with sparing of iris. Tissue thermal damage was minimal in PDT controls. Eyes treated with the Nd:YAG laser exhibited full-thickness thermal necrosis of iris, ciliary processes, and a fibrinous iridocyclitis. In contrast, eyes treated by PDT were quiet with thrombosis of superficial blood vessels. Conclusion: Tissue photon penetration is good at 770 nm and thermal effects from the exciting laser alone were minimal. The ciliary processes of pigmented rabbits exhibit a selective retention of SINc and on that basis can be selectively destroyed with a minimum on thermal damage to nontarget tissues.

All compounds were characterized by NMR, IR, and elemental analysis. Thermogravimetric analysis shows the dialkyldithiocarbamates to decompose around 350-400 degrees C and the monoalkyl derivatives to decompose at a lower temperature, 100-150 degrees C. Only the diisopropyl and the two monoalkyl derivatives decompose cleanly to CaS; all the other dialkyldithiocarbamates decompose to a highly carbonized product. The crystal structures of two dithiocarbamates, Ca(S2CN(CH2)(4))(2)((CH2)(4)NH)(2) (3a) and Ca(S2CN(H)(CH2)(3)NMe2)(2)(THF)(2).H2O (7a), and a calcium thiocyanate byproduct Ca(NCS)(2)(THF)(4) (8a) were determined.

Many of these ranges accommodate force-on-force battles, including simulated firings of weapons and of kills against the opponent; the physical variables used in these simulated kills (times of events, locations of players) are then available for computer replays, as well as investigations of the effects of changes to some battle details. This paper describes the use of player and event time-location data to visually portray some aspects of synchronization of forces, one of the classic (and current) battlefield tenets.

These descriptions were to be data-based and objective, providing useful critiques of actual performance according to standard Army doctrine. They would be natural candidates for use at the Army's Combat Training Centers. The project was conducted in two phases. In the first, objective graphic displays were derived which portray the destructive potential of direct fire weapons (the shooter must be able to see the target) in the defense. These displays allow straightforward objective comparisons of different defensive alignments and, from simulated battle runs, of defensive fire control strategies. These references also describe simple uncluttered displays that portray the movements and interactions of company (or higher) sized units throughout a battle. This paper describes results of the second phase of the BEAM project. A major result is the derivation of displays which portray the destructive potential of indirect fire weapons (the shooter normally cannot see the target) in the defense using the same units as the direct fire displays.

When this involves modeling through computer simulation (or even tracking units in a field test over actual terrain), the terrain is usually represented as a digital terrain map for computational purposes. With a digital terrain map, the terrain surface is represented as a simple surface (often a step function) over a two-dimensional domain covered by a tesselation of squares or hexagons. As the size of the underlying units (let us assume squares) in the domain is reduced, the resolution of the map increases, but the computational cost of preparing, storing and using the map increases exponentially. Thus, there is a question of how high the resolution needs to be for a given application. We study this question from the point of view of accuracy of intervisibility calculations as a function of terrain resolution. The approach involves computation of theoretical total intervisibility with varying levels of terrain resolution over simple ''pseudo terrains'' having assumed mathematical forms. It is found that intervisibility approximations based on digital terrain rapidly approach the theoretical limiting intervisibility as resolution is increased. Relationships between intervisibility surfaces and current military doctrine concerning location of defending forces at the ''military crest'' are discussed.

The SEAS project synergistically applies current leading edge technology and ideas which allow the investigation and understanding of the multimedia sources of data collected at the NTC. With the SEAS tools, an analyst or any user can create a Janus scenario that will accurately represent the actions occurring at the NTC. With a scenario of a unit's actual rotation, commanders can conduct extensive pre and post rotation training and investigate 'what if' excursions that are based upon alternate enemy courses of action. SEAS will assist in maintaining a high quality of training in units by providing an added dimension to a commander's training capabilities.

The Lanchester area fire model and the Helmbold equations were modified to allow the lethality of the defending blue force to be increased as they gained more combat intelligence about the attacking red force, thus modeling intelligence as a true combat multiplier. By adjustments made to parameters in the model, the lethality of the blue's direct and indirect fire weapons could be adjusted based on the quantity and quality of their intelligence assets. With information from a computer database, and the COMAN model, maximum likelihood attrition rate estimates were calculated for both red and blue forces for ten heavy defensive battles conducted at the Army's National Training Center. In each battle, the red force attrition rate was fit to a curve which represented a percentage of blue's full potential, represented here by the square law. Using this model in a combat simulation, and with some preliminary work with comparable systems, one could implement a change in blue's intelligence assets and then provide a quantitative measure of the effect that this had on the outcome of a battle.

Techniques must be used to conduct operational testing using a minimum of resources while not sacrificing the adequacy and credibility of the test. A coordinated use of a combat simulation and a design of experiment procedure, the Taguchi method, shows promise as an acquisition strategy. This research focused on the Javelin medium antitank system which just completed operational testing in the Fall of 1993 and was intended to give the Javelin Project Manager's office information regarding the probable outcome of critical design characteristics prior to the test. Using the Taguchi method, many different design parameters were analysed at several different levels of performance. The method reduced the number of trials required to obtain a desired level of statistical significance while still obtaining the necessary data for each parameter. Once the required number of trials were identified, the janus combat model simulated the operational test trials. Results suggest what weapon parameters are critical to the specific measures of effectiveness of survivability, lethality, and engagement range. In a broader view, this tandem use of an experimental design technique and a combat simulation can provide acquisition managers with insights on critical system parameters prior to actual testing.

It was observed that different sequences are obtained depending on the wavelength, Lambda, and average composition < C >. In large wavelength samples, the metastable Al9Ni2, phase is the first phase to be formed whereas, in short wavelength samples, Al3Ni or AlNi are formed first depending on < C >. The importance of interdiffusion and nucleation in phase selection and sequence of phase formation is discussed taking into account the asymmetry in diffusivities and the finite supply of Al and/or Ni. Analysis of the isothermal traces indicates that diffusion of Ni in Al is controlling the initial phase formation and that the asymmetry in diffusivity favors the formation of Al-rich phases. However, the Al-rich phases will eventually be by-passed if diffusional impingement occurs in the early stage to eliminate the supersaturated region (volume) associated with their formation. Thus, while an invariant sequence of phase formation is expected in an infinite diffusion sample configuration, phase sequencing will vary in finite configurations.

Particular emphasis is devoted to the matching of observed convective rainfall, inferred from the Microwave Sounding Unit (MSU), with that produced by NOGAPS' Arakawa-Schubert cumulus parameterization scheme. To accomplish the matching, the model's specific humidity field is adjusted at each time step during a pre-forecast integration period. This adjustment consists of adding a perturbation in relative humidity, with linear vertical profile, to the model's relative humidity; the amplitude of the perturbation is proportional to the difference between observed and model precipitation rates. Results show significantly improved rainfall accumulations during the period in which the model is forced with the observed precipitation. However, this positive impact largely disappears within 24 hours after the forcing is removed, that is, the model has difficulty in maintaining the assimilated rainfall on its own. Possible explanations for this problem are considered, one of the more likely being the model's low resolution. RP VanTuyl, AH (reprint author), USN,RES LAB,7 GRACE HOPPER AVE,MONTEREY,CA 93943, USA.

Advanced data assimilation methods, such as the extended Kalman filter, are theoretically capable of performing this task; but, at this time, little work has been undertaken. Daley (1994) constructed a one-dimensional extended Kalman filter (EKF) system to examine this problem. This work is extended here to include a more systematic examination of the one-dimensional case, together with experiments with non-divergent two-dimensional flow. The emphasis is on determining when wind recovery is likely to be successful or unsuccessful. It was found that wind recovery is most successful with the EKF for constituent observations which are dense, frequent and accurate. Wind recovery is difficult or slow for the EKF (or any other procedure) when the true constituent time-tendency is small. This happens when the constituent spatial gradient is small, the true windspeeds are low or the streamfunction and constituent fields are highly correlated. Wind recovery can also be difficult with constituent transport models which are highly damped, have significant phase errors or restrictive CFL criteria. Steady winds cannot be recovered inside data voids, although time-dependent winds may be recoverable. If constituent observations are too infrequent, estimates of the constituent time-tendency will be poor, and wind recovery (at least for the EKF) problematic.

In this study, the mechanisms of initiation and maintenance of the convective clouds and precipitation are investigated. A fully-compressible fine resolution nonhydrostatic mesoscale numerical model is used in this study. Surface energy and moisture budget were included in this model to simulate the diurnal cycle of ground surface temperature and wetness. The model also has a sophisticated boundary layer and explicit cloud physics. A sounding obtained from Orlando, Florida at 1110 UTC 17 July 1991 as part of the Convection and Precipitation Electrification (CaPE) experiment is used for initialization. The initial data for the model is kept in geostrophic and thermal wind balance. Several sensitivity tests were conducted to investigate the effects of different treatments of ground surface moisture and temperature on the model forecast of the convection and precipitation induced by the sea breeze circulations. The simulations agree reasonably well with the observations when both surface energy and moisture budget were included in the model to predict ground surface temperature and wetness. The surface moisture has a significant impact on the formation, strength, sustenance, and the location of convection and precipitation induced by the sea breezes. C1 USN,RES LAB,WASHINGTON,DC 20375.

The near-infrared (IR) transmission spectra of these filters have a sharp cutoff at a wavelength that scales linearly with the channel diameter, as expected for hollow metallic waveguides. Cutoff wavelengths approaching lpm have been achieved to date using NCG materials with sub-micron channel diameters. The spectra are dominated by a strongly resonant transmission peak just above the cutoff wavelength, where the peak transmission can be as much as twice that predicted based on the geometrical open area of the NCG structure. The NCG wafers were typically less than 20 mu m thick, and the Au films ranged in thickness up to 600 nm. RP Rosenberg, A (reprint author), USN,RES LAB,WASHINGTON,DC 20375, USA.

Two different sizes (2.3 nm and 3.0 nm) of CdS particles were prepared by varying the conditions of preparation. The size was determined by a combination of UV-vis absorption spectra and X-ray diffraction (XRD). The steep absorption edges of the two CdS samples indicate very narrow size distribution.

These nanowire arrays have novel characteristics: The nanowires are very parallel (to within a fraction of a, degree) and regularly placed. They are circular with extremely uniform diameter (of less than 80 nm for some samples) both along individual wire's length and among different wires within an array. Magnetic measurements show enhanced coercivities compared to the bulk values. The saturation magnetization for Ni nanowires depends much more strongly on temperature than that for Co nanowires. The coercivities are also dependent strongly on temperature and can be explained by a thermal-activation model. RP Nguyen, PP (reprint author), USN,RES LAB,DIV OPT SCI,WASHINGTON,DC 20375, USA.

The indices of refraction of the two glasses differ by less than 0.02 in the relevant spectral region. Narrow attenuation features occur whenever the dispersion relation for light propagating within such a periodic dielectric structure crosses a Brillouin zone boundary. The attenuations corresponding to the first Brillouin zone appear in the near-infrared (IR), at wavelengths between 1 and 3 mu m, in good agreement with calculations.

In FDDI reliability applications, MRA is an attractive alternative to the popular dual homing architecture for the following reason. Unlike the requirement of several reliable concentrators needed in the dual homing architecture, the MRA only requires several routing interfaces at each backbone node (i.e., at each router node); different fiber cables and networks share the same set of routers, creating a set of highly fault tolerant networks of low overall cost and complexity.

The underlying delivery mechanism for IP multicast is presently the User Datagram Protocol (UDP) or raw IP packets. At present, these mechanisms provide a ''best effort'' delivery service. Best effort implies that IP packets are treated with essentially equal weight, and while IP makes an effort to deliver all packets to their destination, packets may be occasionally be delayed lost, duplicated, or delivered out of order. In the past such delivery mechanisms have worked fine for supporting traffic insensitive to occasional lost or missing data (e.g.. voice, video). An increasing variety of distributed multimedia applications are being developed in which a consistent and/or reliable data delivery of all or a subset of data packets is a critical performance factor. In future military tactical internetworks,, situational awareness data will play a major role as a critical multicast application. Reliable group file transfer(e.g.. image dissemination) and interactive mission planning applications me also likely applications for military mobile units. This paper presents a taxonomy of presently available reliable multicasting solutions. The protocols are classified in terms of performance issues and scalability. Using this taxonomy, reliable multicast solutions are considered for various military applications such as mission planning, Distributed Interactive Simulation (DIS), and situational awareness dissemination in a shared WAN environment.

The signal is transmitted through a Rician fading channel with both wideband thermal noise and partial-band noise interference, The receiver structure examined is the self-normalized combining receiver with diversity, The self-normalized receiver minimizes the effects of hostile partial-band interference, while diversity alleviates the effects of fading, We find that with the implementation of soft decision Viterbi decoding, the performance of the self-normalized receiver improves dramatically at moderate signal power-to-interference power ratios, Coding drives the jammer to a full band jamming strategy for worst case performance, Nearly worst case jamming occurs when barrage jamming is employed and there is no diversity except in cases where there is very strong direct signal. When the energy per bit and the total spread bandwidth is held constant, performance degrades slightly with increasing diversity except in instances of a very weak direct signal. When the spread bandwidth expands with increasing diversity, the jammer is forced to spread its power over a wider bandwidth and diversity offers some performance advantage.

Multicast routing is an effective means of providing the efficient utilization of network resources required to realize such an environment. Traditional multicast routing algorithms assume a symmetric network topology. Many military communication assets are either asymmetric in their load or asymmetric in capacity (a good example is Direct Broadcast Satellite). In addition, many military communication assets are bandwidth constrained and routing symmetrically may further contribute to congestion. Therefore, multicast tree construction which tolerates network asymmetry is desirable for many military communication environments. This paper proposes an algorithm for constructing shared multicast distribution frees in networks with asymmetric link capacities or loads. The algorithm tolerates asymmetry by building distinct, loop-free, sender and receiver paths onto a shared delivery tree. Additionally, the algorithm exhibits desirable security properties. Simulation results are presented that demonstrate the lower tree cost and better load balancing characteristics of the resultant trees over shortest path trees, with only a modest increase in path length.

In this paper, characterizations of the unclassified network traffic from the Synthetic Theater of War-Europe (STOW-E) demonstration are assessed in the context of self-similarity. At small time scales, the LAN traffic oscillates between burstiness and smoothness, whereas the WAN traffic exhibits smoothness. However, both the LAN and the WAN traffic exhibit high burstiness on larger time scales. Therefore, the traffic shows characteristics that would be produced by Poisson-type and self-similar processes. Additionally, in comparing the STOW-E traffic with an asymptotically self-similar process, we find that it has unusually high Hurst parameter (i.e., H similar to 1). A simple mathematical model for the traffic is an uncorrelated process whose parameters vary according to another asymptotically self similar process of high burstiness. Since a combination of self-similar processes results in an asymptotically self-similar process, we conjecture that future STOW traffic should behave as asymptotically modulated self-similar processes.

Results indicate that time delays and angle of arrival errors vary dynamically in seasons, months, and regions. The error in both time delay and angle of arrival are higher than expected, and should not be neglected for higher accuracy requirements in elevation angles of less than 10 degrees.

At-sea evacuations are dangerous, expensive, and may compromise the mission of the vessel. Therefore, Group Medical Officers and IDCs were trained to use the Navy Computer-Assisted Medical Diagnosis (NCAMD) system during deployment. They were then surveyed to evaluate the NCAMD system, Their responses show that NCAMD is a cost-efficient, user-friendly package, It is easy to learn, and is especially valuable for training in the diagnosis of chest and abdominal complaints, However, the delivery of patient care at sea would significantly improve if computer hardware were upgraded to current industry standards. Also, adding various computer peripheral devices, structured forms, and reference materials to the at-sea clinician's resources could enhance shipboard patient care.

It is purposefully made so in order to prepare military personnel for the long, stress-filled hours of combat It is a time when recruits are molded into stronger, more disciplined individuals. This study investigated the stress levels and coping skills of recruits during boot camp. The Undergraduate Stress Questionnaire, State-Trait Anxiety Inventory, and the Ways of Coping Questionnaire mere distributed to 48 recruits during weeks 1, 5, and 8 of training. Results of the Undergraduate Stress questionnaire indicated that the most stressful period was week 5. This was statistically significant (p < 0.001) compared to weeks 1 and 8. Results of the State-Trait Anxiety Inventory indicated that state anxiety was highest during week 1, and was statistically significantly higher (p < 0.05) compared to weeks 5 and 8. The Ways of Coping Questionnaire indicated that problem solving was the most frequently used coping skill, followed by self control and accepting responsibility. The least used coping skill was escape/avoidance. Conclusions to be drawn from this study suggest that weeks 1 and 5 are very stressful for the recruits; however, a majority of them coped adequately with the stress by employing effective coping mechanisms. Implications include enhancing effective coping mechanisms already in place. Recruits with ineffective coping skills require anticipatory guidance and close surveillance, with possible psychiatric intervention. Replication of this study with a greater number of subjects and female recruits is indicated, as are studies that correlate physical symptoms with stress levels.

A Job Activities Inventory containing three types of job descriptors (tasks, behaviors, and abilities) was developed, and judgments on job activities and requirements were collected for 75 Navy entry-level ratings (jobs). Job-level component scores were derived to form the basis for grouping the jobs into descriptor-specific families. Each job's cluster membership was then cross-tabulated across the different cluster analysis solutions to form ''tree diagrams.'' These job family trees represent a job's cluster membership across a number of cluster solutions, and they organize and present job characteristic data in ways different from traditional occupational analyses. Several applications of multibasis job characteristic information are discussed. C1 USN,CTR PERSONNEL RES & DEV,SAN DIEGO,CA 92152.

Three groups of trainees were presented with subject matter in paper-based prose form (text), paper-based question-and-answer form (test), or computer-based gaming form (game). These conditions were selected to investigate potential benefits of computer-based gaming over traditional paper-and-pencil media in terms of trainee performance and reaction. Results showed that participants assigned to the game condition scored significantly higher on a retention test compared to pretest performance. Furthermore, participants assigned to the game condition scored significantly higher on a retention test than did participants assigned to the text condition. Participants assigned to the test and text conditions showed no benefit from training in performance at the retention test. In addition, participants assigned to the game condition rated the training they received as more enjoyable and more effective than did those assigned to the other 2 conditions. Results are discussed in terms of the effectiveness of computer-based games for military training applications.

One such issue is whether results from computer-administered surveys are equivalent to those obtained from paper-and-pencil surveys. After a review of relevant Navy studies, we concluded that computer and paper surveys generally yield equivalent results. The Navy's efforts and success at computerizing command-level equal opportunity surveys is described, and the advantages of this approach are discussed. The Navy's survey work on diversity issues (e.g., Hispanics, sexual harassment, and pregnancy) is described and the problems posed by attempting to use surveys to identify who is Hispanic and to determine accurate rates of sexual harassment and pregnancy are outlined. Future issues to be addressed by Navy survey research are discussed. C1 USN,CTR PERSONNEL RES & DEV,SAN DIEGO,CA 92152. DEF MANPOWER DATA CTR,ARLINGTON,VA. USN,HLTH RES CTR,SAN DIEGO,CA 92152.

Methods used to correlate theory with experiment are explained, and the dependence of the beam profile on tip sharpness, gate diameter, anode distance, and tip work function are examined. It is shown how the analytic model may be extended to find the trajectories needed for particle simulations. Analysis has shown that the rms spread angle is approximately 20 degrees.

This model explains many of the observed features of the cuprates including the temperature and frequency dependence of the surface resistance and penetration depth, the anomalous temperature dependence of the upper critical magnetic field, and the zero bias anomalies observed between cuprates and normal metal contacts. This model can also explain many of the phase coherence experiments in YBaCuO on the basis of magnetic scattering at an interface or grain boundary due to strain-induced oxygen loss.

The mission would place the new spacecraft in a heliocentric orbit and well off the Sun-Earth line, where it can simultaneously view both the solar source of heliospheric disturbances and their propagation through the heliosphere all the way to the earth Joint observations, utilizing the new spacecraft and existing solar spacecraft in earth orbit or L1 orbit would provide a stereographic data set. The new and unique aspect of this mission lies in the vantage point of the new spacecraft, which is far enough from Sun-Earth line to allow an entirely new way of studying the structure of the solar corona, the heliosphere and solar-terrestrial interactions. The mission science objectives have been selected to take maximum advantage of this new vantage point. They fall into two classes: those possible with the new spacecraft alone and those possible with joint measurements using the new and existing spacecraft. The instrument complement on the new spacecraft supporting the mission science objectives includes a soft x-ray imager, a coronagraph and a sun-earth imager. Telemetry rate appears be the main performance determinant. The spacecraft could be launched with the new Med-Lite system.

The coronagraph is one of the three channels comprising the LASCO(2) coronagraph and the only channel with spectroradiometric capabilities. Among the primary science objectives assigned to the Lyot coronagraph are the determination of the mechanisms responsible for the acceleration of the solar wind and the heating of the corona(3). Spectrometric and spectropolarimetric coronal observations made with the Lyot coronagraph are used in support of these and other objectives. We describe the Lyot instrument design from the imaging coronal spectrometer perspective. The rationale for use of a tunable Fabry-Perot interferometer as the spectral resolving element is outlined. The relationship between spectral resolving power, interferometer diameter, telescope entrance stop diameter and coronal field of view as it applies to LASCO is reviewed. Performance requirements imposed on the interferometer by the coronal source and the science objectives are described. The optical, mechanical, electronic and semi-automated control designs as well as the interferometer modes of operation are summarized. The actual flight model Fabry-Perot interferometer performance allows the instrument to operate with high luminosity and with finesse values high enough to provide approximately optimal passband widths and reasonable tunable ranges about useful spectral features. We conclude with some early results indicative of the flight performance of the instrument. RP Socker, DG (reprint author), USN,RES LAB,EO HULBURT CTR SPACE RES,WASHINGTON,DC 20375, USA.

Improvements in detector technology, optics and optical coating technology, and almost two decades of analysis of SO82A data can be combined with the basic concept of an EW objective grating spectrograph to build an instrument to address many of the remaining mysteries of solar flares. This next generation instrument incorporates two sets of two identical, orthogonally mounted slitless spectrographic Cassegrain telescopes. Each telescope consists of a multilayer coated, Wadsworth mount objective grating and multilayer coated spherical secondary mirror; a backside illuminated CCD detector is installed at the focal plane. The orthogonal mounting changes the dispersion direction by 90 degrees on the disk image; processing on the two resulting images allows recovery of the undispersed disk image and spectral line profiles. The resulting instrument will obtain high time cadence, spectrally-dispersed images with improved spatial resolution, dynamic range, signal-to-noise ratio, and velocity discrimination.

The chiral order of the copolymer, measured by optical activity, is dominated by whichever enantiomer is in the majority. We present a quantitative theory for this cooperative chiral order, using a mapping of the random copolymer onto the random-field Ising model. Using this theory, we predict how the sharpness of the majority-rule curve can be controlled for applications in a optical switch. We also consider how this theory could be applied to chiral order in DNA. C1 CATHOLIC UNIV AMER,DEPT PHYS,WASHINGTON,DC 20064.

The ptmA gene encodes a protein of predicted M(r) 28 486 which shows significant homology to a family of alcohol dehydrogenases from a variety of bacteria. The ptmB gene encodes a protein of predicted M(r) 26 598 with significant homology to CMP-N-acetylneuraminic acid synthetase enyzmes involved in sialic acid capsular biosynthesis in Neisseria meninigitidis and Escherichia coli K1. Site-specific mutation of either ptmA or ptmB caused loss of reactivity with antisera specific to the post-translational modifications and a change in the isoelectric focusing fingerprints relative to the parent strains. Mutation of ptmB, but not of ptmA, caused a change in apparent M(r) of the flagellin subunit in SDS-PAGE gels. The ptmA and ptmB genes are present in other strains of Campylobacter. In a rabbit model the ptmA mutant showed a reduced ability to elicit protection against subsequent challenge with heterologous strains of the same Lior serotype compared to the parental wild-type strain. This suggests that the surface-exposed post-translational modifications may play a significant role in the protective immune response.

In variants of C. coli strain VC167, two antigenic flagellin types determined by sere-specific antibodies have been described (termed T1 and T2). Post-translational modification has been suggested to be responsible for T1 and T2 epitopes, and, using mild periodate treatment and biotin hydrazide labelling, flagellin from both VC167-T1 and T2 were shown to be glycosylated. Glycosylation was also shown to be present on other Campylobacter flagellins. The ability to label all Campylobacter flagellins examined with the lectin LFA demonstrated the presence of a terminal sialic acid moiety. Furthermore, mild periodate treatment of the flagellins of VC167 eliminated reactivity with T1 and T2 specific antibodies LAH1 and LAH2, respectively, and LFA could also compete with LAH1 and LAH2 antibodies for binding to their respective flagellins. These data implicate terminal sialic acid as part of the LAH strain-specific epitopes. However, using mutants in genes affecting LAH serorecognition of flagellin it was demonstrated that sialic acid alone is not the LAH epitope. Rather, the epitope(s) is complex, probably involving multiple glycosyl and/or amino acid residues. C1 UNIV VICTORIA, DEPT BIOCHEM & MICROBIOL, VICTORIA, BC V8W 3P6, CANADA.

The single grid version of the NRL model used in the study has 16 layers in the vertical with a horizontal resolution of 1/3 degrees longitude and 1/4 degrees latitude. The primitive equation, hydrostatic model in sigma coordinates includes parameterized physics of cumulus convection, radiation, and the planetary boundary layer. The National Meteorological Center (NMC) Regional Analysis Forecast System (RAFS) analysis is used to provide the initial and boundary conditions. Starting from the 0000 UTC 4 January RAFS initialization, the control model simulates the ensuing cyclo-genesis, deepening the initial disturbance from 998 to 952 mb in 24 h. While the simulated cyclone is about 15 mb weaker than that observed, the simulation reproduced many of the well-documented observed features of the IOP 4 cyclone, such as the remarkable comma-shaped precipitation pattern, bent-back warm front, warm-core seclusion, and secondary cold front. Control model results show that(i)the strongest temperature and water vapor gradients are aligned with the warm front and secondary cold front, not the primary cold front, (ii) the major precipitation and strongest vertical motion are along the warm front and its bent-back extension, (iii) the cyclonic circulation is displaced well to the southwest of the triple point, and (iv) the cellular convection occurs behind the secondary cold front accompanied by extreme surface sensible and latent heat transfer with a total maximum flux exceeding 3000 W m(-2) over the Gulf Stream approximately 100 km offshore of the Carolinas. A detailed analysis of model results is performed and is found to be in excellent agreement with available satellite and mesoscale observations. Sensitivity experiments are also conducted to identify the importance of various dynamical and physical processes contributing to the rapid intensification. Results from sensitivity tests show that (i) the dynamic processes are more responsible for the rapid intensification and unique structure of the marine cyclone than the physical processes, (ii) both the sea surface heat transfer and the release of latent heat in clouds contribute positively to the cyclogenesis, (iii) physical processes combine to intensify the storm in a nonlinear fashion, and (iv) the formation of unique features associated with the IOP 4 storm such as the bent-back extension of the warm front, warm-core seclusion, and westward development of the low pressure center away from the triple point are not sensitive to physical processes.

Vesicles were prepared from mixtures of charge-neutral phospholipid, 1,2-bis(tricosa-10, 12-diynoyl)-sn-glycero-3-phosphocholine, and palladium ion-bound negatively charged phospholipid, 1,2-bis(tricosa-10, 2-diynoyl)-sn-glycero-3-phosphohydroxyethanol. The divalent palladium ion bound to the negatively charged phospholipids in the vesicle membrane initiated electroless metallization of gold or cobalt on the vesicle surface leading to the formation of metallic nanoparticles. By using the internal volume of polymerized vesicles as the reaction vials, two types of unagglomerated nanoparticles, Au (4-10 nm) and Co/Co(OH)(x) (30-100 nm), have been synthesized. Metallization of unpolymerized vesicles resulted in the formation of size controlled, unagglomerated Au nanoparticles (20-28 nm). Dry powders of the Au particles were redispersable in water. TEM results suggest that composites of lipid and metal were formed. For both the polymerized and unpolymerized vesicles, HRTEM studies have demonstrated that particle nucleation and growth occurred at the vesicle membrane surfaces and that particle growth could be initiated by either single or multiple nucleation sites.

One approach involved the sonochemical decomposition of organometallic precursors; and the other involved the reduction of the metal halides with lithium triethyl borohydride followed by vaccum sublimation of the powders to remove lithium chloride. The as-synthesized powders are amorphous by X-ray diffraction (XRD) but the peaks corresponding to bcc alpha-Fe are observed in the compacts. The morphology and composition of the powders synthesized by both techniques, as well as the compacts, were examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Hardness, density, particle size and impurity contents were also determined for the compacts. In addition, pure nanosized iron particles obtained by the ultrasound decompositon of iron pentacarbonyl were consolidated and the properties of the latter were studied.

The requirements for the design were for a ship to operate in littoral areas of the world with a mission of deterring regional conflicts and of hampering the efforts of the aggressor in such a conflict. In addition the ship's mission included the evacuation of friendly personnel as hostilities become likely. The problem countering the littoral threat during times of constrained budgets is addressed. Top level requirements for the design, generated in parallel with ''.... From the Sea'' [1], were used to set the design goals. The paper describes the manner in which littoral warfare changes the nature of the challenges faced by Navy surface combatants, including a ship such as the RDS 2010. A number of factors become more crucial design concerns than for blue water ships, including reduced reaction times, likelihood of attack from hidden land sites, shallow water mines and shallow water USW Certain other factors become less critical in littoral areas and this also has ship design impacts. While some present ship designs can perform some of the tasks needed in a littoral warfare/regional conflict environment, none represents a completely integrated design (hull, mechanical & electrical; combat systems; fiscal and manning constraints; reduced vulnerability; robust self-defense etc.) for a vessel stationed in waters that, without warning, can become hostile. After describing the mission requirements to which the RDS 2010 was designed, the paper discusses the controlling design philosophy and decisions and describes the process used to assess threats to the ship. The process of combat system selection, against the backdrop of expected threat scenarios, is described and the intended approach to integration of the combat system is discussed. In recognition that decreased reaction times and surprise attacks are likely to threaten a ship engaged in regional deterrence, discussions oi features intended to reduce ship vulnerability and crew casualties are presented in the paper. A description of the characteristics oi the final design is presented and accompanied by a design evaluation. The authors also present suggestions for further investigation of promising design features and technologies for employment in such a ship. The paper includes a discussion of lessons learned in the process of producing the design and includes appropriate acknowledgments. The design was performed at the Naval Postgraduate School under the direction of author Calvano by a group of four officer students, which included author Riedel.

N2O5 is produced by the gas phase oxidation of dinitrogen tetroxide (N2O4) with ozone (O-3) (i.e., N2O4 + O-3 --> N2O5 + O-2). Ozone is produced on site at an approximate rate of one pound per hour with a concentration of 8% in oxygen. The N2O4-ozone gas phase reaction takes place in a plug flow reactor. Four reactors in parallel are available to accommodate various production rates. The N2O5 collects as a solid in four parallel trains of three traps in series, each trap suspended in a dry ice/acetone solution.

One system making use of these developments is the ComScan, an x ray backscatter tomography system developed by Philips, At NRL we have had considerable success with the ComScan in developing a one-sided NDT procedure for Navy Sonar Domes. We have had the opportunity to apply the instrument to several other NDT problems with mixed success.

Therefore, understanding the interaction of the ultrasonic waves with boundaries and defects is of great importance for the accurate interpretation and modelling of these phenomena. An experimental apparatus which makes use of the photoelastic effect is described. This apparatus permits full-field visualization of the stresses (strains) produced by ultrasound and its interaction with boundaries and defects inside a transparent material. This relatively inexpensive and easy to use experimental system employs a high brightness light emitting diode (LED) as the light source and a video camera as the receiver. The output of the video camera is sent to a frame grabbing board for image capture and manipulation by a PC computer. The photoelastic system was developed in order to have experimental results to compare with results of a numerical model based on the use of a parallel computer and to make any necessary modifications to the model. The actual parameters used for the physical experiment are input as data to the model [1]. The output of the parallel computer (Connection Machine or CM) is also in the form of a full-field image and can be compared to the experimental results in nearly a one-to-one manner.

Specially prepared graphite/epoxy panels are inspected with an open-ended waveguide reflectometer at various frequencies and liftoffs. The results show the possibility of manipulating signal polarization (with respect to the fiber orientation) to detect embedded materials. For cross-ply laminates, the microwave signal is almost totally reflected off of the surface and no appreciable signal penetration is possible. However, impact damage, a surface defect, is detected both in unidirectional and cross-ply laminates. These preliminary results are encouraging for the use of microwave signals when inspecting certain graphite composite structures.

This suggests averaging the density-functional and Hartree-Fock eigenvalues for use in a time-dependent Hartree-Fock calculation.

For example, in shallow water with a downward refractive (summer) sound speed profile, the noise vertical directionality is expected to show a deep (>10 dB) null in the horizontal direction for wind generated noise below 1 kHz. This ''horizontal null'' is a consequence of the fact that low order modes are weakly excited by the noise sources which are located near the ocean surface. This phenomenon has been experimentally observed and is not expected to occur in a upward refractive (winter) sound speed profile environment. However, when internal waves are present, the deep null may disappear or significantly weaken due to the ''strong'' mode coupling effect caused by the scattering of the noise field from the internal waves. In the internal wave fields, the conversion of higher order modes (generated by the surface noise sources) to low order modes by the internal waves can fill in the deep (> 10 dB) null which would otherwise be expected. We present numerical calculations of the vertical noise directionality at frequencies below 1 kHz for typical shallow water environments and investigate the potential effects of internal waves on the ambient noise directionality. The numerical simulations are compared with ambient noise directionality recently measured in an area south of Long Island which showed the presence and absence of the ''null'' at different times. The fill-in of the null can be explained by noise from distant ships when internal waves are present. RP Yang, TC (reprint author), USN,RES LAB,WASHINGTON,DC 20375, USA.

Two traditional approaches to solving this problem are removing the data that cause the anomalies, or smoothing the data prior to final gridding and contouring. One form of smoothing that can be done employs a Filter that predicts regional trends in the data and enhances local trends possibly correlated with auxiliary information, For example, there if a general tendency for oceanographic temperature profiles to be well-correlated within localized regions of similar bathymetry. By choosing a filter that takes such tendencies for localized spatial coherence of data into account, trends that are obscured due to the sparsity of data may be enhanced and more easily seen in the contoured grid. Such considerations led to the development of a two-part smoothing filter that uses simple cross-validation and least squares to fit data, in this case SST dare, to a regional surface that depends on all the data in the target area, and to localized surfaces delineated by bathymetric range, The regional surface is fit to the SST observations. The errors in the regional fit are then fit to individual surfaces defined over localized areas as delineated by a common range of bathymetry. The data are then interpolated to tile nearest grid cell center only if the cell if supported by data. The filter was applied to SST data from the Yellow Sea and the cast coast of the United States. The results showed a large improvement in the climatological representation over most of the respective areas, but was not able to resolve stable current patterns without additional special processing.

It is a well defined physical quantity that can be measured experimentally with a vertical array. It possesses certain deterministic features that can be modeled theoretically with environmental acoustic and source data. Ambient noise in coastal shallow waters, including its vertical directionality, is not very well known and also difficult to model/predict. This is because the acoustic environment varies with time and is location dependent. Thus arises the question ''How does the vertical directionality of the ambient noise depend on the acoustic environments (found in typical coastal waters)?''. We note that due to the shallow water depth, sound (noise) propagation can be significantly influenced by the bottom. How much bottom interaction will depend on the sound speed profile in the water column: whether it is downward refractive or not. Bottom attenuation will in turn determine how far the sound will propagate in the water column. Using a modal representation, we obtain a closed form expression which can be used to interpret and predict the noise vertical directionality as a function of the environmental acoustic parameters. As the deterministic features of the noise vertical directionality is controlled by the sound propagation in the channel, it could be used as an acoustic indicator of the acoustic environment in the area.

For example ocean bottom mapping needs drove the development of improved sidescan sonars that can produce high resolution images of the bottom. With high resolution images pattern recognition techniques have been able to classify bottom types automatically. But not all sonars produce high resolution images. Other sonar systems require longer range capabilities and therefore give up the ability to produce high resolution images. In this case other signal processing methods, some relying on neural networks, have been successful in classifying bottom types. This paper will describe requirements, sonar systems, and signal processing methods that were applied by the Oceans' community over the last 6 years satisfying technological challenges.

This project was undertaken to provide additional information to the port's pilots about the currents at this location, so that they may continue to safely guide ships to and from Port Everglades. A major goal of the system's design was to optimize the usefulness of the real time current information gathered by an Acoustic Current Profiler (ACP) for non-scientific users. The Naval Surface Warfare Center, Carderock Division's South Florida Testing Facility (SFTF), under contract from PEP Inc., the Port Everglades Pilot Association's corporate entity, developed and installed a real time port entrance current monitoring system with automatic voice information data retrieval.

The method requires measurement of reverberation and ambient noise spectra in the band, and a prediction of signal energy as a function of frequency for a trial waveform. The amount of improvement over the trial waveform is high when there are large fluctuations of the reverberation-to-ambient noise ratio in the band. Thus. the method is most useful for wideband systems. RP Baggenstoss, PM (reprint author), USN,UNDERSEA WARFARE CTR,NEWPORT,RI, USA.

Horizontal profiles of turbulence are obtained using two piezoceramic shear probes sampling shear orthogonal to the vehicle's direction of motion, a single ultrafast thermistor, and three orthogonal accelerometers, all mounted on a sting. Horizontal profiles of optical absorption and attenuation are obtained with a WET Labs AC-9 instrument mounted in a wet well, with the proper flow rate provided by a pump, Field trials in the Narragansett Bay tidal estuary in January 1996 resulted in obtaining turbulence and optical data in the mid-water pycnocline, as well as in the ocean surface layer during wind row occurrences.

For example a 24 beam system in the 20 kyd search mode, which was used in the demonstration of the real-time automated system, would have to perform nearly a million FFT's per ping cycle just to do matched filtering. In order to accomplish real-time decision making the algorithms were developed on a massive parallel computer. The actual computer utilized was MASPAR's MP-2 with 4096 parallel elements. System development utilized Fortran-90 and MP-2 library routines. The paper will discuss the real-time decision making requirement for a 24 beam active sonar system, describe the sequential detection algorithm and the sequential classifier algorithm, the parallel array mapping algorithm that was the key to achieving real-time throughput. In the search mode of an active sonar system all possible range and bearing locations are processed for targets for each ping. A Decision making algorithm then decides if the target is of interest. It was demonstrated that a sequential detection algorithm and a sequential classifier algorithm could process data in real-time that automatically detects and classifies targets by integrating over several pings. However on each ping decisions can also be made. Both the sequential detector and classifier can be designed to look for low SNR targets or high SNR targets. These design settings affect the performance of the algorithm in terms of probability of detection and probability of false detection. The purpose of this paper is to describe the automated algorithms and the parallel array mapping algorithm for a 24 beam active sonar system operating in a 20 Kyd range mode.

There are two main innovations that characterize the approach. The first innovation is to break down the classifier into four sub-classifiers, each targeting a different target characteristic. These characteristics are : (a) echo spatial and temporal shape, (b) echo amplitude, (c) echo tracking consistency, and (d) doppler. The classifier forms a likelihood statistic for each characteristic which is represented in the display symbols. The second innovation is the use of parameters for conditioning the distributions which sets the stage for environmental adaptability. The paper stresses system design and not performance.

In the past 5 years, advancements have been made in using existing hull-mounted multibeam bathymetric systems as imaging systems. These hull-mounted systems are optimized for bathymetry, whereas the towed systems have been optimized for imagery. Two separate surveys were performed using both the University of Hawaii, Hawaii Institute of Geophysics (HIG) Acoustic Wide-Angle Imaging Instrument, Mapping Researcher 1 (HAWAII MR1 or MR1) system and the Navy's hull-mounted multibeam Sonar Array Survey System (SASS) over the same area, The MRI operates at 11 kHz (port) and 12 kHz (starboard), transmitting and receiving on two rows of elements mounted on each side of the tow body. It has a variable pulse length ranging from 0.5-10 msec, and a sample rate of 1 l(Hz. In contrast, the SASS system has a hull-mounted transmit array with a multiple element receive array, pulse lengths from 3-7 msec, and a sample rate of 333 Hz. The study area covers depths ranging from 100-2000 m. Examples of three different morphological areas will be shown: canyons on a continental shelf and slope, a large debris flow at the base of the slope and, pockmarks possibly associated with underlying biogenically produced gas. System characteristics, signal and image processing for each of the systems, and a quantitative comparison of the two data sets, including the spatial scales of detectable features, are presented.

Special products to support fleet and amphibious forces have been developed and are being provided by NAVOCEANO, NAVOCEANO conducts multidisciplinary military oceanographic surveys, The office collects oceanographic, hydrographic, chemical, navigation, and acoustic data, Seabed topographic classification, composition, and load-bearing strength are essential to amphibious operations, mine burial/detection, special operations, etc, (see Fig, 1), Until recently the mapping of littoral oceans bottom was laborious and sketchy, Bottom grabs, photography, divers' observations, or sidescan sonar imagery analysis were the sources of this information. These data-gathering approaches were either very accurate but labor intensive or low quality, Both approaches produced minimum coverage. Gathering dependable environmental data in the littoral seas is time dependent, The littoral regions are dynamically complex, everchanging, NAVOCEANO's ability to respond to Naval Expeditionary Force operations in a timely manner requires a new approach to the science of seabed classification, NAVOCF,ANO is utilizing a data-collection and processing device to meet these requirements: RoxAnn(TM), a hydro-acoustic system marketed from Scotland by Marine Micro Systems, Ltd, This system has been operated from full size oceanographic survey vessels and small hydrographic survey launches (HSLs), Once calibrated and ground-truthed, seabed topographic classification can be accomplished at normal survey speeds and without interfering with normal multidisciplinary environmental data-gathering operations [1], Seabed classification has entered a new era using digital technology that offers an opportunity for larger scale mapping and efficiency to respond to special tactical fleet operations.

However, several studies have shown that profound anesthesia is not always achieved. The electric pulp tester has been used to measure the level of local dental anesthesia during endodontic therapy. However, no study has been performed that evaluates the ability of the electric pulp tester to predict the efficacy of local anesthesia prior to an operative procedure. If ineffective anesthesia could be predicted, supplemental injections could be administered to alleviate the anesthetic problem. The purpose of this study was to evaluate the ability of the electric pulp tester to measure the level of local anesthesia prior to operative treatment. The study was performed in vivo on patients requiring operative therapy. All teeth were pulp tested preoperatively for vitality using the electric pulp tester. After injection of local anesthesic, traditional parameters of dental anesthesia were verified (lip numbness, mucosal sticks). Teeth were then retested with the electric pulp tester and the results recorded. The teeth were then prepared for restoration using conventional instrumentation, and the patient's level of anesthesia evaluated using a visual analog scale. The electric pulp tester readings were compared to the patient's responses using Fisher's Exact test (two-tail). The results indicate that the electric pulp tester can be a valuable tool in predicting potential anesthetic problems in operative (restorative) dentistry.

Methods: Photorefractive keratectomy (6.0-mm ablation zone) was performed on 30 Navy/Marine personnel (-2.00 to -5.50 diopters [D]; mean, -3.35 D). Glare disability was assessed with a patient questionnaire and measurements of intraocular light scatter and near contrast acuity with glare. Results: At 1 year, all 30 patients had 20/20 or better uncorrected visual acuity with no loss of best-corrected vision. By cycloplegic refraction, 53% (16/30) of patients were within +/-0.50 D of emmetropia and 87% (26/30) were within +/-1.00 D. The refraction (mean +/- standard deviation) was +0.45 +/- 0.56 D (range, -1.00 to +1.63 D). Four patients (13%) had an overcorrection of more than 1 D. Glare testing in the early (1 month) postoperative period demonstrated increased intraocular light scatter (P < 0.01) and reduced contrast acuity (with and without glare, P < 0.01). These glare measurements statistically returned to preoperative levels by 3 months (undilated) and 12 months (dilated) postoperatively. Two patients reported moderate to severe visual symptoms (glare, halo, night vision) worsened by PRK. One patient had a decrease in the quality of night vision severe enough to decline treatment in the fellow eye. Intraocular light scatter was increased significantly (>2S D) in this patient after the procedure. Conclusions: Photorefractive keratectomy reduced myopia and improved the uncorrected visual acuity of all patients in this study. Refinement of the ablation algorithm is needed to decrease the incidence of hyperopia. Glare disability appears to be a transient event after PRK. However, a prolonged reduction in the quality of vision at night was observed in one patient and requires further study. C1 USN,HLTH RES CTR,SAN DIEGO,CA.

Appliques consist of a free-standing sheet of black material and an adhesive or other means for attaching the applique to a substrate. In this paper the optical scatter in the visible and infrared of black appliques from Battelle, Dupont, Edmund Scientific, Energy Science Laboratory, Inc. (ESLI), Rippey and Rodel is reported and compared to Martin Black. The Rippey and Rodel appliques are sold as polishing cloths for the semiconductor industry, whereas the ESLI applique was originally developed as a low sputter yield coating. The Battelle applique consists of a carbon loaded polyurethane film with a surface which is heat molded into a micro-grooved pattern, The ESLI applique consists of high aspect ratio fibers mounted in an adhesive base and was the blackest applique of all those investigated. For an incidence angle of 10 degrees, a scattering angle of 45 degrees and a wavelength of 632.8 nm, the BRDF of the best ESLI applique was 3x10(-4), compared to 1x10(-3) for the best Battelle applique, 1.5x10(-3) for a representative Martin Black sample and 1.8x10(-3) for the Edmund applique. The Battelle applique is quasi-diffuse due to its surface microstructure, with a higher BRDF (2-5x10(-3)) at scatter angles less than 15 degrees. For a wavelength of 10.6 mu m, an incidence angle of 7.5 degrees and a scatter angle of 45 degrees, the BRDF of the ESLI coating (1x10(-3)) was slightly higher than Martin Black (8x10(-4)), with the Battelle applique exhibiting strong dependences on scatter angle and groove orientation. In the 2-14 mu m spectral range, the directional hemispherical reflectance of the ESLI coating at a 20 degrees incidence angle is below 0.45% and only weakly dependent on incidence angle to 60 degrees. In-plane and cross-plane BRDF measurements at 3.39 mu m are reported on a 'biased' ESLI coating which is designed for use at near grazing incidence. In-plane BRDF measurements at wavelengths of 0.6328 and 10.6 mu m are reported for most of the appliques studied.

Such conclusions about the uniqueness of static and dynamic spatial abilities seem premature, however, since only a limited number of dynamic spatial tasks have been utilized in research and these have differed markedly from their static counterparts. In the present studies, tasks were designed to require a common mental operation (mental rotation) under static and dynamic conditions. Correlations between static and dynamic performance ranged from .80 to .90. This appears to suggest that the emergence of a unique dynamic ability factor depends on the utilization of certain specialized tasks (e.g., arrival time tasks) with mental operations much different than those required by conventional spatial tests. In other words, it is apparently the requirement for different cognitive processes and not the processing of stimulus motion per se that distinguishes performance on some dynamic tasks from performance on some standard static tasks.

These local-density approximation calculations correctly show the absence of a ferroelectric instability in this compound. Phonon frequencies and bulk properties in good agreement with existing measurements are obtained. A highly anharmonic low-frequency mode corresponding to the observed incipient ferroelectric behavior is identified. The electronic structure shows strong transition metal oxygen covalency as in known ferroelectric perovskites. As expected properties similarity with KNbO3. The absence of ferroelectricity in KTaO3 is due to the extreme sensitivity of the soft mode to the covalency and the slight chemical differences of Nh and Ta, particularly the higher d binding energy in Nb.

We employ the rescaled isotropic-scattering solution to the time-dependent radiative transfer equation to examine three mathematically distinct limits of photonic transport: the ballistic, quasidiffuse, and diffuse limits. In all cases we follow the constraint that a minimum fractional number of launched photons must be received before the time-integrating detector is turned off. We show how the achievable ballistic resolution maps into the diffusion-limited achievable resolution, and verify this behavior experimentally by using a coherently amplified Raman polarization gate imaging system. We are able to quantitatively fit the measured best achievable resolution by empirically rescaling the scattering length in the model. C1 USN,RES LAB,LASER PHYS BRANCH,WASHINGTON,DC 20375.

We explain this majority rule theoretically by mapping the random copolymer onto the random-field Ising model. Using this model, we predict the chiral order as a function of enantiomer concentration, in quantitative agreement with the experiments. and show how the sharpness of the majority-rule curve can be controlled.

Evidence is presented that the same interface defects are produced for all three degradation methods and that hydrogen is the active agent causing the degradation. P-b centers do not account for all of the defects responsible for fast states, and E' centers are not responsible for most of the slow states. Results suggest that the hydrogen-induced fast states may be in the oxide transition layer near the silicon-oxide interface and that hydrogen is part of the defect responsible for the slow states.

The theoretical analysis is based on the assumption that each beam segment has a prescribed current profile at the drift tube entrance. A closed integrodifferential equation for beam current is obtained in terms of time and propagation distance. Properties of the current and energy modulations are investigated from the integrodifferential equation for a broad range of system parameters. The current modulation amplitude decreases, reaches its minimum value, and increases as the beam propagates downstream. By linearizing the integrodifferential equation for beam current for small modulation, it is shown that the current modulation in the linear regime is a sum of the forward and backward density waves. On the other hand, the energy modulation in the linear regime is a difference between the forward and backward density waves. Several points are noteworthy from the current and energy modulations in the linear regime. First, the maximum current modulation occurs at the propagation distance, where the forward and backward density waves have the same intensity and sign. The corresponding energy modulation is zero. Second, the maximum energy modulation occurs at the propagation distance, where the forward and backward density waves almost cancel each other and where the corresponding current modulation is least. Third, wavelength of the amplitude oscillation in modulations increases with beam energy and decreases with beam intensity. (C) 1996 American Institute of Physics.

The goals of proposed reforms are couched in similar language - economy, efficiency, improvement, or just better budgeting.... However, any effective change in budgetary relationships must necessarily alter the outcomes of the budgetary process. Otherwise, why bother? Far from being a neutral matter of 'better budgeting,' proposed reforms inevitably contain important implications for the political system, that is, the 'who gets what' of governmental decisions (Wildavsky, 1961: p. 186). ...budgeting is a subsystem of politics, not vise versa - because of the current tendency to overload budgeting. As much as I respect the importance of budgeting and the talents of budgeteers, to substitute budgeting for governing will not work (Wildavsky, 1992b: p. 439).
