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 ...

THIS PROPOSAL IS A REQUEST FOR AN EVALUATION OF AN AIRFLOW MONITOR AND STALL WARNING DEVICE ON A HIGH PERFORMANCE AIRCRAFT EXHIBITING THE CHARACTERISTICS OF A MODERN JET TRANSPORT. THE DEVICE PROVIDES A METHOD OF SENSING LOCAL AIRFLOW PHENOMENA OVER AN AIRCRAFT WING, INCLUDING THE TRANSITION FROM LAMINAR TO TURBULENT FLOW, AND USING THIS PHENOMENA TO PREDICT THE APPROACH TO A STALL. THE DEVICE EMP ...

FEASIBILITY RESEARCH AND DEVELOPMENT OF A NON-DESTRUCTIVE TESTING AND EVALUATION METHOD, DOUBLE PULSED CCD PHASE SAMPLED LASER SPECKLE METROLOGY (DPLSI) IS PROPOSED. THIS TECHNOLOGY HAS THE POTENTIAL OF MAKING IT POSSIBLE, IN AN INDUSTRIAL CONTEXT, TO ANALYZE THE TEMPORAL AND STATIC DEFORMATION OF BOTH MATERIALS AND ASSEMBLIES, WITH NO CONTACT, TO A RESOLUTION IN SPATIAL DISPLACEMENT OF 0.25 M AND ...

THE INNOVATION TO BE DVELOPED IS A PROTOTYPE DISTRIBUTED CONCEPT ORIENTED EXPERT SYSTEM FOR APPLICATION TO SPACECRAFT ANALYSIS MONITORING AND CONTROL. SYSTEM FUNCTIONS WILL BE PERFORMED BY SEMI-AUTONOMOUS EXPERT MODULES WORKING TOGETHER UNDER THE COORDINATION AND CONTROL OF A SUPERVISORYEXPERT . CONCEPT ORIENTED REPRESENTATIONS OF BOTH KNOWLEDGE BASE AND LOGICAL PROCESSES WILL BE EMPLOYED THROUGHO ...

A PROOF OF PRINCIPLE EXPERIMENT IS BEING CONSTRUCTED THAT WILL CLEARLYDEMONSTRATE THE ESSENTIAL ELEMENTS OF ARRAY OPERATION. AN OSCILLATOR AND TWO AMPLIFIER SECTIONS ARE BEING SUBJECTED TO PERFORMANCE TESTS. PHASE ARRAY OPTICAL RADARS OR LIDARS OPERATING WITH RELATIVELY LARGE SYNTHETIC APERTURES CAN EXHIBIT MANY OF THE SAME RAPID POINTING AND TRACKING FEATURES ASSOCIATED WITH MICROWAVE SYSTEMS, AN ...

THE UNPRECEDENTED POINTING AND TRACKING ACCURACIES REQUIRED IN STRATEGIC DEFENSE ENGAGEMENT SCENARIOS PRESENT FORMIDABLE CHALLENGES TO THE DESIGNERS OF PLATFORM CONTROL SYSTEMS FOR SLEWING AND VIBRATIONSUPPRESSION. IT IS CLEAR THAT CONVENTIONAL DESIGN PROCEDURES BASED ONFINITE DIMENSIONAL, LUMPED PARAMETER MODELS (FINITE ELEMENTS OR MODES)ARE INADEQUATE TO THE TASK. ADVANCED DESIGN METHODS ARE BEI ...

POLYMERIC OR CERAMIC INSULATORS CONVENTIONALLY ARE BEING USED IN HIGH VOLTAGE PULSED SYSTEMS. NEW APPROACHES ARE NEEDED THAT WOULD REDUCE INSULATORS RING THICKNESSES AND INCREASE CORRESPONDING GRADING RINGS FLASHOVER VOLTAGE. SUCH AN APPROACH WOULD POSSESS IN COMPARISON TO CONVENTIONAL INSULATORS: HIGHER SURFACE FLASHOVER FIELD STRENGTH; SMALLER PHYSICAL DIMENSIONS FOR EQUIVALENT VOLTAGE HOLDOFF; ...
