WE PROPOSE TO BUILD A MICRO-BASED VERSION OF NASA'S RECON CITATION SYSTEM. THIS WILL ENABLE NASA TO DECENTRALIZE THE RECON DATABASE AND THUS GREATLY ENHANCE ITS POWER. THE PRODUCT WILL EMPLOY OUR INNOVATIVE "VIEWCACHE" STORAGE APPROACH WHICH USES A REVOLUTIONARY DATABASE ACCESS METHOD FOR INCREMENTAL SEARCH IN A LIBRARY OF CITATIONS. THIS SYSTEM WILL BE DESIGNED AS AN ADD ON ENHANCEMENT OF THE DIS ...

THE DIGITAL ACTIVE MATERIALS-PROCESSING PLATFORM EFFORT BE- ING PROPOSED HERE SEEKS TO DEVELOP AN ACTIVELY STABILIZD PLATFORM UPON WHICH MICRO-G MATERIALS PROCESSING EXPERIMENTSCAN BE PERFORMED IN SPACE. WITH THE SUC- CESSFUL COMPLETION OF THE TWO-STEP PHASE I WORKPLAN APPLIED TECHNOLOGY ASSOCIATES (ATA) HAS CLEARLY AND SUCCINTLY DEFINED THE PROBLEM OF PLATFORM ISOLATION IN SPACE AND HAS COMPLETEL ...

ASTRONAUTS AND ANIMALS FLOWN IN MICROGRAVITY HAVE EXPERIENCED A LOSS OF RED BLOOD CELL MASS, BUT MECHANISMS CAUSING THIS PHENOMENON ARE NOT UNDERSTOOD. PREPARATIONS FOR IN-FLIGHT HEMATOLOGY STUDIES INCLUDE A DESIRE TO ELIMINATE RADIOACTIVE TRACERS AND SUBSTITUTE SAFE STABLE ISOTOPES. REALISTIC MULTIPLE SAMPLING FOR IN-FLIGHT STUDIESWILL REQUIRE MICROLITER 'PIN-PRICK' BLOOD SAMPLES. ACCURATEMEASURE ...

LASER RADAR (LADAR) IMAGING HAS BEEN POSTULATED AS PROVIDING DATA SIGNIFICANT TO ROBOTIC VISION. WE PROPOSE TOADD DOPPLER VELOCITY MEASUREMENT TO EXISTING 3D AND INTENSITY IMAGING AND AN INTERACTIVE PROGRAMMABLE SCANNER/SIGNAL PROCESSOR CONCEPT, USING LONG RANGE CO2 LASERHETERODYNE IMPLEMENTATION. A DUAL FOV SCANNER APPROACH WILLBE INVESTIGATED TO ALLOW SIMULATNEOUS WIDE FOV BODY TRACKINGAND NARRO ...

THE PROPOSED RESEARCH IS AIMED AT IMPROVING THE UNDERSTANDING OF THE EFFECT OF MICROGRAVITY ON VAPOR TRANSPORT AND CRYSTAL GROWTH. TO ACHIEVE THIS GOAL IT IS VERY IMPORTANT TO DESIGN AND OPTIMIZE SYSTEMATICALLY GROUND BASED EXPERIMENTS WHICH IS THE FOCUS OF THIS RESEARCH. THE PAST EXPERIMENTAL WORK ON THE SUBJECT HAS BEEN CARRIED OUT ON COMPOUNDS (I.E. HGI(2), GESE-GEI(4), GESE-XE). THE CHEMICAL C ...

A BASIC UNDERSTANDING OF THE MECHANISMS OF SURFACE HEATING OF AIRCRAFT IS CRUCIAL TO THE DEVELOPMENT OF NEW MATERIALS WHICH REDUCE HEATING EFFECTS. THE GOAL OF THE PROPOSED RESEARCH IS THE DEVELOPMENT OF INNOVATIVE THEORETICAL APPROACHES TO GAIN AN UNDERSTANDING OF THE MICROSCOPIC MECHANISMS OF GAS/SURFACE INTERACTIONS, CHEMICAL ENERGY ACCOMMOCATION, AND SURFACE CATALYTIC REACTIONS. IN THE THEORET ...

GAS/SUFFACE INTERACTIONS AND RECOMBINATION REACTIONS WHICH ARE THE KEY ELEMENTARY PROCESSES RESPONSIBLE FOR SURFACE HEATING IN HYPERSONIC AEROTHERMODYNAMICS (HA) WILL BE COMPUTATIONALLY EXPLORED. THE INNOVATIVE TECHNOLOGY THAT THE RESEARCH PROPOSED HERE WILL EMPLOY DRAWS FROM THE EMBEDDED ATOM METHOD, THE EMBEDDED DIATOMICS IN MOLECULES METHOD, THE QUASICLASSICAL TRAJECTORY METHOD, MOLECULAR DYNAM ...
