Award Data

CONCENTRATION FLUCTUATION MEASUREMENTS OF A TRACER GAS CAN PROVIDE INFORMATION REGARDING THE DISPERSION AND TRANSPORT OF AN AIR MASS. THERE HAS BEEN A DEARTH OF SUCH DATA BECAUSE OF A SHORTAGE OF INEXPENSIVE, SIMPLE-TO-OPERATE INSTRUMENTATION MEETING THE NECESSARY REQUIREMENTS OF FAST RESPONSE, HIGH SENSITIVITY, AND STABILITY. IT IS THE GOAL OF THIS RESEARCH PROGRAM TO DEVELOP AN INEXPENSIVE, HIGH ...

APPLIED TECHNOLOGIES, INC. PROPOSES A DESIGN PROGRAM TO DESIGN A SIMPLE, MOBILE, VERTICAL AXIS FM-CW RADAR. THE PROGRAM WILL ENCOMPASS A LITERATURE SEARCH TO FIND THE LATEST STATE-OF-THE-ART ADVANCES IN RADAR TECHNOLOGY. THE DATA FROM THE LITERATURE SEARCH WILL FORM THE BASIS FOR A DESIGN THAT INCLUDES ANTENNA DESIGN, TRANSMITTER DESIGN, RECEIVER DESIGN, AND DATA COLLECTION AND PROCESSING. COST TR ...

THIS PROPOSAL DESIGNS A MAN PORTABLE AND DEPLOYABLE FOOTBRIDGE WITH THE BRIDGING CAPABILITY TO CROSS A 20 METER DRY GAP AND AN UNLIMITED WET GAP. THE BRIDGE IS DEPLOYABLE QUICKLY AND QUIETLY, AND ONLY REQUIRES ACCESS TO ONE SIDE OF THE GAP. THE DESIGN USES NEW LIGHTWEIGHT, HIGH-STRENGTH MATERIALS ALONG WITH STATE-OF-THE-ART COMPUTER OPTIMIZATION TECHNIQUES TO MAXIMIZE LOAD TO BRIDGE WEIGHT RATIOS. ...

A SIMILAR METHOD TO MEASURING ICE ON A VIBRATING WIRE IS USED TO MEASURE PERSISTENT ICE ON SMALL STRUCTURES. THE MEASURMENT OF VIBRATION OF STRUCTURAL MEMBERS WILL UTILIZE AN ACCELEROMETER; IT PRODUCES A VERY SENSITIVE RESULTS FOR A WIDE DYNAMIC RANGE OF ATTACHED ICE MASS. A SMALL TAPPING MECHANISM WILL BE DEVELOPED TO INDUCE FREQUENCY VIBRATION. SIGNAL CONDITIONING AND PROCESSING ARE PROPOSED, IN ...

MANY INSTRUMENTATION RADARS (SUCH AS THE MPS-36 AND FPS-16) USED AT WSMR AND OTHER RADAR INSTALLATIONS WORLDWIDE WERE DESIGNED 20-30 YEARS AGO. THIS PROPOSAL ADDRESSES ENHANCEMENTS TO THESE OLDER RADAR SYSTEMS TO INCORPORATE MODERN SIGNAL PROCESSING TECHNIQUES USING A DIGITAL COMPUTER AND SOFTWARE TO PROVIDE IMPROVED TRACKING, TO PROVIDE COHERENT DATA FOR TMR AND OTHER USES, TO PROVIDE IMPROVED RE ...

THIS PROPOSAL IS TO APPLY COMPUTATIONAL FLUID DYNAMIC (CFD) SIMULATIONS TO DESIGN SLUGLESS HIGH VELOCITY PULSE SHAPED CHARGE WARHEADS FOR ARMOR PENETRATION. WE HVE DEVELOPED A NEW AND VERY NOVEL CODE ELPIC (EXTENDED LAGRANGIAN PARTICLE IN CELL CODE) WHICH OVERCOMES THE NORMALLY ENCOUNTERED DIFFICULTIES OF BOTH EULERIAN AND LAGRANGIAN CFD CODES FOR THESE PROBLEMS. USING THIS HIGHLY RELIABLE AND EFF ...

WHILE MILITARY APPLICATIONS OF MIDAND FAR-INFRARED SENSING ARE INCREASING, THERE ARE VERY FEW TECHNOLOGIES AVAILABLE FOR LIGHT MODULATION IN THOSE SPECTRAL BANDS. WE PROPOSE TO DEVELOP NON-MECHANICAL SHUTTERS USING THE ELECTRO-OPTIC EFFECT IN FERROELECTRIC LIQUID CRYSTALS. THE SHUTTERS WE PROPOSE WILL BE SMALL AND RUGGED, AND HAVE HIGH THROUGHHPUT (70-90%), HIGH ON:OFF CONTRAST (40:1 OR GREATER), ...

A PROGRAM TO EVALUATE EM CONTROL, DEVELOP THE OVERALL DESIGN PHILOSOPHY AND MEANS TO MEANS TO MEASURE THE CONTROL EFFECTIVENESS WILL BE THE GOAL OF THE PROPOSED EFFORT. THE PROGRAM IS OUTLINES IN THIS PROPOSAL. A DATA BASE FOR THE NEW TECHNOLOGY IS TO BE OBTAINED AS THE FIRST SUBTASK; INCLUDING THE DEFINITIONS OF THE EM THREAT WAVEFORMS (EMI, EMP, EW AND ECM, LIGHTNING AND STATIC ELECTRIFICATION), ...

HIGH POWER MICROWAVE (HPM) DIRECTED ENERGY WEAPONS POSE A THREAT TO SYSTEMS WHICH EMPLOY ADVANCED INTEGRATED CIRCUITS (VLSI/VHSIC). THESE CIRCUITS, WHICH USE SMALL GEOMETRY DEVICES, ARE SUSCEPTIBLE TO UPSET AND DAMAGE DUE TO THE LARGE CURRENTS AND VOLTAGES WHICH COUPLE TO THE PRINTED CIRCUIT BOARDS FROM HPM SOURCES. ELECTROSTATIC DISCHARGE PROTECTION IS INADEQUATE FOR THE REPETITIVE PULSE NATURE O ...
