THE PROPOSED EFFORT IS TO DEVELOP A COMBINED HARDWARE AND SOFTWARE SYSTEM BASED ON DATA'S CLIPBOARD COMPUTR. THE CLIP BOARD IS AN IBM PC COMPATIBLE PORTABLE COMPUTER WITH BASIC DIMENSIONS OF 7"X10"X1.5" AND A WEIGHT OF 4 POUNDS. IT CON-TAINS A HIGH RESOLUTION (640 X 200) GCA MONITOR WITH A TOUCHSCREEN FOR MENU RESPONSE ENTRY BY FINGERTIP. THE COMPUTER RUNS A 8 MHZ HAS 3 MB OF A MAIN MEMORY (COMBIN ...

AN ACTIVE STRUCTURAL VIBRATION CONTROL SYSTEM IS BEING DEVELOPED FOR STRATEGIC DEFENSE ORBITAL PLATFORMS. THIS SYSTEM IS EMPLOYING FIBER OPTIC SENSORS EMBEDDED IN COMPOSITE LAMINATED STRUCTURAL ELEMENTS TO ACHIEVE A RUGGED INTEGRATED SENSOR AND CONTROL SYSTEM RESULTING IN HIGH MANEUVERABILITY AND POINTING STABILITY. THIS CONCEPT OFFERS PARTICULAR ADVANTAGES IN TERMS OF DISTRIBUTED SENSOR PLACEMENT ...

THERMAL MANAGEMENT OF FLUCTUATING POWER IN SPACECRAFT IS AIDED BY THE USE OF SUITABLY PLACED THERMAL ENERGY STORAGE (TES), WHICH OFTEN USES LATENT HEAT OF PHASE-CHANGE MATERIALS (PCMS) FOR THE STORAGE MEDIUM. AN OUTSTANDING PROBLEM WITH TES IS HOW TO GET THE THERMAL RESPONSE FAST ENOUGH TO ACCOMMODATE PULSE-POWER SITUATIONS. TO ADDRESS THIS NEED, THE FEASIBILITY IS BEING DEMONSTRATED OF HIGH-FLUX ...

AN ANALYTICAL METHODOLOGY IS BEING DEVELOPED THAT IS CAPABLE OF DETERMINING THE OPTIMUM COMBINATION OF TEMPORALLY/SPATIALLY DISTRIBUTED PULSED-LASER AND HYPERVELOCITY IMPACTS NEEDED TO CAUSE SEVERE DAMAGE TO POSTULATED MULTITHREAT, MULTILAYER STRATEGIC ASSET STRUCTURES AND STRUCTURAL HARDENING CONCEPTS. THE METHODOLOGY ALSO WOULD ALLOW THE THEORETICAL DETERMINATION OF HARDENING CONCEPT MODIFICATIO ...

A GLASS BOTTLE CONTENTS VERIFICATION SYSTEM BASED UPON NUCLEAR MAGNETIC RESONANCE (NMR) RELAXATION SIGNATURES IS PROPOSED. AS ENVISIONED, THE PROPOSED SYSTEM WILL ACCOMMO- DATE THE EXPECTED WIDE RANGE OF FLUID TYPES AND BOTTLE SIZESIN ADDITION, UNLIKE SYSTEMS BASED UPON HIGH-RESOLUTION NMR TECHNIQUES, THE PROPOSED BOTTLE CONTENTS VERIFICATION SYSTEMWILL OPERATE WITH MODEST MAGNETIC FIELD STRENGTH ...

THE ADDITION OF SMALL QUANTITIES OF OXYGEN INTO A THERMIONIC CONVERTERHAS LONG BEEN RECOGNIZED AS A POSSIBLE MEANS OF ALLOWING A WIDER INTERELECTRODE SPACING WITHOUT PERFORMANCE PENALTY OR ALTERNATIVELY OFIMPROVING THE OUTPUT PERFORMANCE CHARACTERISTICS RELATIVE TO A CONVERTER WITHOUT THE OXYGEN ADDITIVE. TO DATE, ONLY EMPIRICAL APPROACHES TO ACHIEVING OXYGEN ADDITION HAVE BEEN REALISED, WITH QUAL ...

THE DEPARTMENT OF TRANSPORTATION (DOT) IS REQUIRED TO MAIN- TAIN THE NATION'S BRIDGES AND ENSURE THEIR SAFETY. HOWEVER,A LARGE NUMBER OF BRIDGES HAVE NOT BEEN RECENTLY INSPECTED TO DETERMINE IF THEY ARE CAPABLE OF SAFELY SUPPORTING THE TRAFFIC THAT IS CROSSING THEM. THE CURRENT METHOD OF SURVEYING BRIDGES, TO DETERMINE THEIR STRESS CONDITION, IS COSTLY AND TIME-CONSUMING. THIS PROGRAM WILL DEVELOP ...

THE NEED EXISTS FOR A HIGHLY SURVIVABLE, LOW COST, SPACE NUCLEAR ELECTRIC POWER SUPPLY THAT WILL BE CAPABLE OF DELIVERING 6 KWE OF STEADY POWER FOR LONG PERIODS OF TIME WITH HIGH RELIABILITY. ANY CANDIDATE SPACE POWER SUPPLY SYSTEM MUST SURVIVE SEVERE ENVIRONMENTAL CONDITIONS, INCLUDING NATURAL RADIATION IN ORBIT, MICROMETEORITES, ANDDEBRIS AS WELL AS HOSTILE THREATS SUCH AS GROUND AND SPACE-BASED ...

ANY VERY HIGH LEVEL LANGUAGE (VHLL) FOR STRATEGIC DEFENSE REQUIRES A COMPILER. NEW META COMPILERS USING ADVANCED ARTIFICIAL INTELLIGENCE METHODS ARE BEING STUDIED SO THAT EVENTUAL VHLL APPLICATION SOFTWARE CAN BE EFFECTIVELY PORTED TO THE SEVERAL GROUND-BASED/SATELLITE-BASED MACHINES. TO DO SO REQUIRES A META COMPILER THAT CAN COMPILE CODE TO DIVERSE ARCHITECTURES. RESEARCH WITH META COMPILERS DEM ...

AN ORDER OF MAGNITUDE INCREASE IN PASSIVE STRUCTURAL DAMPING IS NEEDEDTO GUARANTEE THE OPERATIONAL ROBUSTNESS OF RETARGETING STRATEGIC DEFENSE SPACECRAFT. FOR CONTINUOUSLY-JOINED PRECISION STRUCTURES OPERATING IN THE VACUUM OF SPACE, MATERIAL DAMPING WILL BE THE DOMINANT SOURCE OF STRUCTURAL DAMPING. ALTHOUGH HIGH DAMPING NON-STRUCTURAL MATERIALS EXIST, THEIR USE RESULTS IN UNDESIRABLE WEIGHT INCR ...
