CONVENTIONAL MOLECULAR BEAM EPITAXY (MBE) GROWTH CONTROL SYSTEMS ARE EITHER OPERATED MANUALLY OR WITH SIMPLE LINEAR CONTROLLERS USING PREDEFINED RECIPES. WE WILL SUPPLEMENT A STANDARD CONTROL SYSTEM WITH A NEURAL NETWORK BASED CONTROLLER. THE NEURAL NETWORK WILL BE TAUGHT BY GROWING GAAS/ALGAAS SUPERLATTICES USING THE CONVENTIONAL TECHNIQUES. SUBSEQUENTLY, THE NEURAL NETWORK WILL BE ALLOWED TO TAK ...

RGI, THROUGH ITS ARRANGEMENTS WITH SCIENCE APPLICATIONS INTERNATIONAL CORPORATION, PROPOSES TO DEMONSTRATE THROUGH ANALYSIS THE FEASIBILITY OF USING MODIFIED VERSIONS OF THE OMAR (OPTICAL MICROWAVE APPROACH AND RANGING) SYSTEM TO ENHANCE THE RELIABILITY OF RPVS. OMAR, CURRENTLY UNDER DEVELOPMENT AS A PRECISION, LOW VISIBILITY LANDING SYSTEM FOR AIRCRAFT (WITH EMPHASIS ON HELICOPTERS), LENDS ITSELF ...

THIS PHASE I SBIR PROPOSAL EXPLOITS RTA'S RECENT DEVELOPMENT OF NONLINEAR DYNAMICS (NLD)-BASED PROCESSING METHODOLOGIES TO THE PROBLEM OF AUTOMATIC AND ADAPTIVE NOISE CANCELLATION. RTA WILL ANALYZE PROPRIETARY TECHNIQUES AND ADVANCES IN THE OPEN LITERATURE, TO IDENTIFY AREAS OF PERFORMANCE. ADDITIONALLY, RTA WILL EXTEND THE THEORETICAL CONNECTION BETWEEN TRADITIONAL NOISE CANCELLATION PROCESSING A ...

To meet dependability requirements dictated by current trends in both defense and commercial technologies, massive modular redundancy and application specific designs will have to give way to more efficient, scalable and cost-effective approaches. This Phase I proposal introduces a method which takes a basic architectural approach to fault-tolerant system design. The proposed research will addre ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...

OVER THE PAST TWO YEARS, WE HAVE GROWN HIGH QUALITY CVD DIAMOND CRYSTALLITES AS CONFIRMED BY RAMAN SPECTROSCOPY, X-RAY DIFFRACTION, AND SCANNING ELECTRON MICROSCOPY ON A VARIETY OF SUBSTRATES INCLUDING SILICON USING A LOW TEMPERATURE (

RAMAN SPECTROSCOPY IS AN EXCELLENT MEANS FOR NON-CONTACT PROBING OF QUALITY AND TEMPERATURE OF MANY MATERIALS (III-V SEMICONDUCTORS, DIAMONDS, ETC.) WHICH ARE GROWN IN CHEMICAL VAPOR DEPOSITION (CVD) REACTORS. IT CAN MEASURE COMPOSITION, TEMPERATURE, STRAIN, DEGREE OF CRYSTALLINITY, AND PRESENCE OF CONTAMINATION EX-SITU. AS AN OPTICAL PROBE IT CAN READILY PENETRATE THE HIGH PRESSURE GASES WHILE A ...

PROPOSED IS A MEANS OF PRODUCING A GENERIC READOUT CIRCUIT FOR INFRARED FOCAL PLANE ARRAYS (IRFPAS) THAT MAY BE USED WITH ANY INFRARED (IR) DETECTOR, OF ANY SIZE AND ARRAY CONFIGURATION, BY ELIMINATION OF THE INDIUM BUMP BONDS USING A NON-CONTACT ELECTRICAL INTERCONNECT. THE CONCEPT IS THE SOLID STATE EQUIVALENT OF A VIDICOM TUBE USING ELECTRON BEAMS GENERATED BY VACUUM MICROELECTRONICS DEVICES (V ...

DOMAIN ANALYSIS (DA) IS THE FIRST STEP IN SOFTWARE REUSE AS IT PROPOSES A SYSTEMATIC, FORMAL AND EFFECTIVE PRACTICE OF SOFTWARE REUSE. UNFORTUNATELY, THE STATE OF THE INDUSTRY IS AT ITS INFANCY STAGE IN DA AND KNOWLEDGE BASE IS NOT READILY AVAILABLE. OUR EXPERIENCE INDICATES HOWEVER, THAT ACQUIRING AND STRUCTURING THE KNOWLEDGE IS THE BOTTLENECK OF DA. DR. RUBEN PRIETO-DIAZ HAS PROPOSED A FORMAL D ...
