ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FRO ...

WE PROPOSE TO DEVELOP A NEW LIGHT SHUTTER APPROACH TO PROVIDE OCULAR PROTECTION FOR PERSONNEL AGAINST LASER RADIATION. THE LIGHT SHUTTER INVOLVES THE APPLICATION OF A REVERSE PHASE MODE POLYMER DISPERSED LIQUID CRYSTAL (PDLC) WHICH HAS BEEN DEVELOPED IN OUR LABORATORIES. THE REVERSE PHASE MODE PDLC SYSTEM PROVIDES LC ALIGNMENT AND THUS GOOD OPTICAL TRANSMISSION IN THE ABSENCE OF ANY APPLIED FIELDS ...

To meet dependability requirements dictated by current trends in both defense and commercial technologies, massive modular redundancy and application specific designs will have to give way to more efficient, scalable and cost-effective approaches. This Phase I proposal introduces a method which takes a basic architectural approach to fault-tolerant system design. The proposed research will addre ...

THE RESEARCH PROGRAM WILL DEVELOP A MICROCOMPUTER BASED SYSTEM OF HARDWARE AND SOFTWARE WHICH WILL ALLOW THE USER TOEXECUTE MAINFRAME BASED CODES ON THE MICROCOMPUTER. IN ADDITION PARALLEL EXECUTION OF SEVERAL CODES AT ONCE IS POSSIBLEA SPECIAL INPUT AND OUTPUT PROCESSOR MODULES WILL ALSO BE DEVELOPED TO DEMONSTRATE THE USER FRIENDLY CAPABILITIES OF THE SYSTEM AND FACILITATE INPUT PREPARATION AND ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...
