THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

A NEW LASER CRYSTAL, PRAESEODYMIUM YTTRIUM LITHIUM FLUORIDE, IS BEING DEVELOPED FOR APPLICATIONS IN HOLOGRAPHIC INTERFEROMETRY. MOST PULSED LASER HOLOGRAPHIC INTERFEROMETRY IS PRESENTLY PERFORMED WITH EITHER FREQUENCY DOUBLED NEODYMIUM YAG OR WITH RUBY LASERS. THERE ARE A NUMBER OF LIMITATIONS IMPOSED BY EITHER OF THESE TWO CRYSTALS, SOME OF WHICH CAN BE OVERCOME BY THE NEW CRYSTAL. RESEARCHERS ...

CURRENT ATTEMPTS TO USE THE PLASMA OPENING SWITCH (POS) FOR DECADE HAVE NOT YET BEEN ENTIRELY SUCCESSFUL DUE TO THE APPARENT INABILITY OF THE SWITCH TO OPEN EFFICIENTLY TO A HIGH-IMPEDENCE LOAD. RESEARCH DIRECTED TOWARD IMPROVING THE PERFORMANCE OF THE POS IN THE LONG-CONDUCTION TIME REGIME HAS BEEN FRUSTRATED BY THE INABILITY OF COMPUTATIONAL TOOLS TO OPERATE IN THE PARAMETER REGIMES OF INTEREST ...

Mission Research Corporation proposes the development of a unique FPGA (field programmable gate array) for applications in space and other military and civilian environments requiring the versatility of reconfigurability with retention of the configuration in an unpowered state. The FPGA will be capable of being configured once and retaining that configuration for a minimum of 10 years even with ...

THE MEASUREMENT OF ATMOSPHERIC WATER VAPOR OR HUMIDITY IS CRITICAL IN MANY RESEARCH AND COMMERCIAL APPLICATIONS. A BETTER KNOWLEDGE OF WATER VAPOR DISTRIBUTION THROUGHOUT THE ATMOSPHERE IS NECESSARY FOR UNDERSTANDING TROPOSPHERIC AND STRATOSPHERIC CHEMISTRY, STRATOSPHERIC-TROPOSPHERIC EXCHANGE, THE GLOBAL HYDROGEN BUDGET, CLUSTER IONS IN THE LOWER IONOSPHERE, AND MESOSPHERIC CLOUDS. SOUTHWEST SCIE ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...
