A COOLING STRATEGY UTILIZING THE ENDOTHERMICITY OF THE PARA- TO ORTHO-HYDROGEN CONVERSION HAS POTENTIAL FOR MEETINGTHE REQUIREMENTS OF AN ADVANCED SUBSYSTEM FOR THERMAL MANAGEMENT IN HYDROGEN-FUELED INJECTION VEHICLES. THE PROPOSED EFFORT WILL DETERMINE THE FEASIBILITY OF DEVELOPINGSUCH A COOLING SYSTEM USING NEW ALUMINA-SUPPORTED FORMULATIONS AS CATALYSTS FOR THE INTERCONVERSION OF PARA- AND ORTH ...

WE INTEND TO APPLY NEURAL NETWORK TECHNOLOGY TO TELEROBOTICS. THIS WILL TAKE ADVANTAGE OF SOME OF THE ADVANCES THAT ARE BEING DONE FOR AUTONOMOUS ROBOTS. THESE CONCEPTS WILL EXTEND THE CAPABILITIES OF THE HUMAN OPERATOR. THE TELEROBOTIC CONTROLLER WILL BE TAUGHT USING BACKWARD SHAPING TO IMPROVE ITS SPEED OF LEARNING. IT IS PROPOSED TO ADD A CAPABILITY FOR ASSOCIATION BASED SENSOR DATA FUSION. THE ...

REALIZATION OF THE PERFORMANCE ADVANTAGES OF SUPERCONDUCTING DEVICES IN HIGH FREQUENCY COMMUNICATIONS DEPENDS ON DEVELOPMENT OF A LOW TEMPERATURE DEPOSITION PROCESS WITH EXACTING CONTROL OF STOICHIOMETRY AND MORPHOLOGY. MOCVD CAN MEET THESE NEEDS COUPLED WITH EASE OFSCALE-UP. HOWEVER, RECENT WORK AT ADVANCED TECHNOLOGY MATERIALS, INC. SHOWS THAT YBACUO AND BISRCACUO FILMS GROWN BY MOCVD AT TEMPERA ...

DUCTILE CHIP FORMATION, UNLIKE THE BRITTLE CHIP FORMATION TYPICALLY OBSERVED IN DIAMOND GRINDING OF CERAMICS, DOES NOTLEAVE BEHIND SURFACE OR SUBSURFACE MICROCRACKS. ACCORDINGLY, MACHINE PROCESSES INVOLVING POLISHING CAN BE ELIMINATED FROM FABRICATION IF MATERIAL REMOVAL DURING GRINDING OCCURS THROUGH DUCTILE CHIP FORMATION. DUCTILE CHIP FORMATION IS ESSENTIALLY AN EXTRUSION PROCESS IN WHICH AN IN ...

FOR ROTORCRAFT IN A NAP-OF-THE-EARTH (NOE) FLIGHT REGIME, COLLISION WITH WIRES PRESENTS A SIGNIFICANT THREAT TO SAFETY. WIRE DETECTION AND AVOIDANCE IS THUS AN IMPORTANT PART OF SAFE NOE GUIDANCE. WIRE DETECTION CAN BE DIFFICULT:WIRES ARE OFTEN NOT STRONGLY SPATIALLY EVIDENT, DANGEROUS WIRES OFTEN OCCUR AT THE FOCUS-OF-EXPANSION (FOE), THERE IS OFTEN SIGNIFICANT BACKGROUND CLUTTER AND NOISE, AND T ...

NETCON (NEW THERMIONIC CONVERTER) IS A NEW IDEA FOR AN ADVANCED POWER CONVERSION SYSTEM. THE EMITTERS ARE TYPICALLY 0.5 CM IN DIMENSION. THE EMITTER AND COLLECTOR ARE SEPARATED BY LESS THAN 0.5 MILS ( 12 MU M), WITH OPERATION IN THE QUASI-VACUUM (UNIGNITED) MODE. THE INTERELECTRODE GAP IS SET BY THE THERMAL EXPANSION OF A CERAMIC PEDESTAL SUPPORTING THE EMITTER. HEAT TRANSPORT TO THE EMITTER IS BY ...

PROJECT OBJECTIVES ARE ADVANCING THE FABRICATION AND DESIGN TECHNOLOGY OF IR DETECTORS FROM BULK HGCDTE TO THE EMERGING TECHNOLOGY OF THIN FILMS; MAKING PROGRESS TOWARD FILMS ON SILICON WAFERS; AND IMPLEMENTING THE TECHNIQUE OF PULSED LASER DEPOSITION (PLD) FOR THE FABRICATION OF THESE HETEROEPITAXIAL-COMPOUND, SEMICONDUCTOR IR DETECTORS. PRESENT METHODS OF MATERIAL GROWTH, FROM BULK PROCESSES TO ...

THE PROPOSED R&D WILL ESTABLISH A NEW CAPABILITY OF LIGHT-ELEMENT X-RAY FLUORESCENCE ANALYSIS THAT SUPPORTS THE ACCURATE QUANTITATIVE MEASUREMENT OF THE BIOGENIC ELEMENTS. THE BASIS FOR THIS NEW CAPABILITY IS A CLASS OF INNOVATIVE X-RAY WAVELENGTH-DISPERSIVE OPTICAL COMPONENTS KNOWN AS LAYERED SYNTHETIC MICROSTRUCTURES (LSM). THESE COMPONENTS, WHEN COMBINED WITH EXISTING ENERGY-DISPERSIVE DETECTOR ...
