A MODULAR INPUT/OUTPUT SUBSYSTEM IS PROPOSED TO PROVIDE INTERFACE BETWEEN EXPERIMENTAL DATA ACQUISITION SYSTEMS USING THE CAMAC OR FASTBUS STANDARDS AND NEW-GENERATION DIGITAL EQUIPMENT CORPORATION MINICOMPUTERS. THE SYSTEM OFFERS A POTENTIAL TENFOLD INCREASE IN THE SPEED OF DATA ACQUISITION OVER CURRENT SYSTEMS. IT INCLUDES SUFFICIENT COMPUTER INTELLIGENCE TO MANAGE DATA TRANSFERS BETWEEN THE EXP ...

THE OXYGEN MOLECULE HAS A NUMBER OF WEAK ABSORPTION LINES INTHE 7000 A SPECTRAL REGION. BY COOLING, THE R1 LINE OF RUBY(A12O3 : CR+3) CAN BE SHIFTED TO COINCIDE WITH 50% ABSORPTION AT LINE CENTER IN THE SOLAR SPECTRUM. RUBY FLUORESCES WITH HIGH QUANTUM EFFICIENCY, WITH A TIME CONSTANT OF APPROXIMATELY 4 MS AT THE TEMPERATURES OF INTEREST. BY DETECTING THE RERADIATED LIGHT, THE RUBY CRYSTAL IS USED ...

THE PROPOSED RESEARCH WILL INVESTIGATE THE DEPOSITION OF AMORPHOUS CARBON THIN FILMS USING A NOVEL LASER ASSISTED DEPOSITION TECHNIQUE. IN THE PHASE I RESEARCH, AERODGNE RESEARCH, INC. WILL DETERMINE THE ABILITY OF THE DEPOSITION TECHNIQUE TO CONTROL THE CARBON BONDING IN THE THIN FILM. IN THE PHASE II STUDIES THEY WILL INVESTIGATE THE RELATIONSHIP BETWEEN DEPOSITION PARAMETERS AND CARBON BONDING ...

THE USEFUL OPERATING LIFE OF MOST MECHANICAL SYSTEMS QUITE OFTEN IS DETERMINED BY THE CONTINUED EFFECTIVENESS OF A VARIETY OF TRIBO-ELEMENTS. THESE TRIBO-ELEMENTS ARE THE DEVICES AND MECHANISMS THAT PROVIDE FOR PROPER LUBRICATION AND FRICTIONAL CONTACT BETWEEN MOVING PARTS. SYSTEMS WHICH CAN MONITOR TRIBO-ELEMENT WEAR CAN PERFORM TWO VERY USEFUL FUNCTIONS: 1) THEY CAN MINIMIZE DOWN TIME BY ENSURIN ...

LEAD IODIDE (PBI2) IS A LITTLE USED COMPOUND SEMICONDUCTOR. THE HIGH ATOMIC NUMBERS OF ITS CONSTITUENT ELEMENTS GIVES ITEXTRAORDINARY PHOTOELECTRIC ABSORPTION EFFICIENCY FOR GAMMA PHOTONS, WHILE ITS 2.5 EV BANDGAP PROMISES PERFORMANCEAT TEMPERATURES UP TO 250 DEGREES C. IT HAS SHOWN SOME PROMISE AS A HIGH EFFICIENCY SOLID-STATE DETECTOR, BUT EARLYDEVICES WERE LIMITED BY MATERIAL IMPURITIES AND IMP ...

ACCURATE MEASUREMENT OF NEUTRONS IS DIFFICULT AND REQUIRES COMPLEX, EXPENSIVE EQUIPMENT. IT IS AN ESPECIALLY SERIOUS PROBLEM FOR DOSIMETRY WHERE SEVERAL TECHMICAL ISSUES MAKE THE ACCURATE DTERMINATION OF RADIATION DOSE EXTREMELY DIF- FICULT. FOR EXAMPLE, NEUTRONS OCCUR OVER A WIDE RANGE OF ENERGIES AND HAVE DIFFERENT PHYSICAL PROPERTIES AS A FUNC- TION OF ENERGY. THE MOST COMMON APPROACH TO MAKING ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

THE PROPOSED PROJECT WILL DEVELOP A NEW DAYLIGHTING DESIGN METHOD BASED ON A "LUMEN-DAY" CONCEPT. THE ESSENCE OF THE LUMEN-DAY METHOD IS A STATISTICAL CLIMATIC DATA BASE, SIMILAR IN CONCEPT TO THE HEATING AND COOLING DEGREE-DAY METHOD OF ENERGY ANALYSIS, GENERATED THROUGH THE INTERROGATION AND ANALYSIS OF TMY/TRY WEATHER TAPES. THE LUMEN-DAY DATA BASE WOULD BE A STATISTICAL SUMMARY OF THE DAYLIGHT ...
