RAPID INTENSE HEATING OF COMPOSITE LAMINATES DUE TO DIRECT ENERGY WEAPONS WILL INDUCE STRONG THERMAL GRADIENTS THAT IN TURN PRODUCE DYNAMIC STRESSES IN THE FORM OF WAVE MOTION. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A MINDLIN PLATE FINITE ELEMENT PROGRAM FOR ANALYSIS OF THE DYNAMIC BEHAVIOR IN A COMPOSITE LAMINATE SUBJECTED TO COMBINED THERMAL/SHOCK AND SIMULATED IN-FLIGHT AERODYNAMIC LOADIN ...

OPTOELECTRONIC SOURCES, INTEGRATED AS MONOLITHIC ELEMENTS ON SILICON VLSI CHIPS, OFFER IMPORTANT ADVANTAGES IN THE TRANSMISSION OF INFORMATION WITHIN THE CHIP OR BETWEEN CHIPS IN ADVANCED COMPUTER SYSTEMS. THE SPEED OF OPTICAL-INTEGRATED VLSI DEVICES IS EXPECTED TO BE CONSIDERABLY HIGHER THAN EQUIVALENT VLSI WITH METALLIC INTERCONNECTS, DUE TO ABSENCE OF THE RC DELAY INHERENT IN THE METALLIC CONDU ...

DESIGN, SIMULATION, FABRICATION, AND EVALUATION OF A PROTOTYPE VERY LARGE SCALE INTEGRATION (VLSI) DATA ACQUISITION SUBSYSTEM IS PROPOSED. AVAILABLE STATE-OF-THE-ART ONE MICRON CMOS TECHNOLOGY MAY ALLOW INCORPORATION OF MORE THAN 128 CHANNELS OF 24-BIT 300 MHZ COUNTERS INTO A SINGLE INTEGRATED CIRCUIT. A PROTOTYPE SYSTEM OF SIMPLE REPEATED CELLS OF COUNTERS, CONTROL AND I/O BUFFERS HAS BEEN DESIGN ...

NEURAL NETWORKS ARE A PROMISING SOLUTION TO SEVERAL PROBLEMS IN THE APPLICATION OF PARALLEL PROCESSING TECHNOLOGY FOR ADAPTIVE RECOGNITIONAND RESPONSE TO COMPLEX PATTERNS. UNFORTUNATELY, IT IS NOT KNOWN HOW TO GET A NEURAL NETWORK TO RECOGNIZE PATTERNS INDEPENDENTLY OF THE VALUES OF THEIR FEATURE PARAMETERS WITHOUT INCORPORATING SPECIAL INVARIANT TRANSFORMS FOR EACH SUCH FEATURE. THIS PROPOSAL INT ...

IT IS PROPOSED THAT A NEW TYPE OF SOFT MAGNETIC MATERIAL CAN BE USED FOR A VERY SENSITIVE AND LOW MAGNETIC FIELD DETECTION DEVICE. TO DETECT THE MILITARY TARGETS, ONE NEEDS A HIGHLY SENSITIVE DEVICE BUT THE EXISTING FLUX-GATE MAGNETOMETERS ARE LIMITED BY THEIR SIGNAL-TONOISE RATIO. WITH THE DEVELOPMENT OF SUPERIOR MAGNETIC MATERIALS AND IMPROVED ELECTRONICS, SOME OF THE NOISE PROBLEMS IN FLUX-GATE ...

Sepax Technologies, Inc. has identified a new type of anoin-exchange resin which separates single-wall carbon nanotubes (SWCNTs) with >80% recovery yield and resolves in a single pass the chiral tubes of (6,5) well from commercial SWCNT starting materials by Chromatography. Improvement and scale up of the targeted resin production will facilitate the separation of chiral nanotubes for the academic ...

Trusted biometric validation of individual identities has never been more important. Several contributing factors are the increase in global terrorism, identity theft and the increase in legislation which are driving the accelerated adoption of biometric technology. Unfortunately, the biometrics industry has not actively responded to the changing market conditions being driven by the explosion in ...

The general objective of this proposal is to design a self-stabilized monolithic single frequency solid state laser. The main advantage of the approach is based on the integration of a laser cavity within active laser material - Nd-doped photo-thermo-refractive (PTR) glass, which allows constructing narrow line unidirectional, environmental insensitive laser. This glass possesses both properties o ...

Currently Unmanned Ground Vehicles are teleoperated, requiring operators to be both vigilant and fully engaged throughout the operation. While increasing the level of autonomy of UGVs potentially reduces both the workload and cognitive load on operators, realizing the promise of autonomy is difficult in deployment. Remote operation of UGVs is subject to unreliable communication and mobility chall ...

Defense Electronics Corporation (DEC) will develop and demonstrate innovative closed-loop control mechanisms for high quality factor Radio Frequency filters or banks of filters for use in frequency-agile radio front-ends. These mechanisms include a hybrid filter control technique using real-time filter response feedback, applications specific integrated circuit (ASIC) or field programmable gate ar ...
