YIELECTRIC COATINGS ON VEHICLES CAN ALTER THEIR RADAR IMAGE SIGNIFICANTLY. THIS PROPOSAL IS DIRECTED TO DETERMINING NUMERICALLY THE REFLECTIVITY FOR AN OBJECT COVERED BY A DIELECTRIC LAYER. A CALCULATION WILL BE DONE USING BASIC PHYSICAL PRINCIPLES TO DEFINE THE THEORETICAL BOUNDARY VALUE PROBLEM FOR THE DIELECTRIC LAYER. THE SOLUTION TO THIS PROBLEM WILL BE OBTAINED NUMERICALLY USING MATRIX INVER ...

Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

WE PROPOSE TO DEVELOP A REPETITIVE, FAST-OPENING SWITCH FOR PULSED-POWER APPLICATIONS EMPLOYING SATURABLE MAGNETIC MATERIALS. THIS TECHNOLOGY HAS PROVEN EFFECTIVE AND RELIABLE IN ELECTRONIC SWITCHING SYSTEMS (ESS) USED IN TELEPHONE EXCHANGES. FOR PHASE I WE WILL DESIGN A PROOF- OF-PRINCIPLE EXPERIMENT; OPTIMIZING THE DESIGN, WHILE TAKING INTO ACCOUNT CONSIDERATIONS OF COST. SUCH A SYSTEM WOULD BE ...

AbTech will survey the hardware and software available to determine what capabilities should be included in an automated office assistant software suite. A language parsing and encoding system in ANN (a leading semantic understanding software package) will be used to parse and encode ASCII output resulting from a voice recognition system such as DragonDictate. The ASCII output from the voice recog ...

DURING PHASE I MISSION RESEARCH CORPORATION PROPOSES TO PERFORM A STUDY OF THE UTILITY OF CAVITY RESONATORS TO INCREASE THE EFFICIENCY AND MODIFY THE BANDWIDTH OF MICROWAVE EMMISSION FROM THE VIRCATOR. THE RESEARCH WILL INCLUDE BOTH A THEORETICAL AND EXPERIMENTAL EFFORT. NUMERICAL SIMULATIONS OF THE CAVITY DESIGN WILL BE CARRIED OUT USING A THREE DIMENSIONAL FULLY RELATIVISTIC AND ELECTROMAGNETIC ...

THIS RESEARCH WILL EXPLORE THE POSSIBILITIES AND RESULT IN THE DESIGN OF AN ACOUSTIC ENERGY GENERATOR FOR GEOPHYSICAL EXPLORATION IN INACCESSIBLE MOUNTAINOUS TERRAIN. THIS EFFORT WILL DETERMINE THE MAGNITUDE OF ACOUSTIC SIGNAL REQUIRED AND WILL DEVELOP A TECHNIQUE FOR COUPLING THE SIGNAL GENERATOR TO THE EARTH. THE COUPLING TECHNIQUE WILL EXAMINE FORCES OTHER THAN GRAVITY TO ENSURE THAT THE SIGNAL ...

VERSAR PROPOSES TO EXAMINE THE EFFECTIVENESS OF COMMERCIALLY AVAILABLE CLAYS SUSPENDED IN LIQUID MEDIA TO REMOVE ORGANOPHOSPHORUS POISON, MUSTARD, PROTEINACEOUS MATERIAL, AND POLYNUCLEOTIDES FROM CONTAMINATED OBJECTS. THIS EFFECTIVENESS WILL BE EVALUATED BY MEASURING AND COMPARING THE COMPONENTS OF THE PARTITIONING/SORPTIVE PROCESS THAT ARE RESPONSIBLE FOR REMOVAL OF THE AGENTS. PHASE I EXPERIMENT ...

EXFLUOR RESEARCH CORPORATION ALONG WITH PROFESSOR RICHARD J. LAGOW AT THE UNIVERSITY OF TEXAS AT AUSTIN HAVE DEVELOPED A NEW SYNTHETIC METHOD FOR PREPARING FLUOROCARBON MEMBRANE MATERIAL. THE PROCEDURE CONSISTS OF FIRST SYNTHESIZING A HYDROCARBON PRECURSOR, INTRODUCING CROSS-LINKS AND THEN FLUORINATING WITH ELEMENTAL FLUORINE. THIS METHOD PERMITS WIDE FLEXIBILITY IN THE STRUCTURAL FEATURES OF THE ...

EACH YEAR A NUMBER OF PREVIOUSLY VISUALLY-QUALIFIED USAFA CADETS BECOME UNQUALIFIED ON THE VISUAL PORTION OF THE PHYSICAL EXAMINATION AND BECOME INELIGIBLE FOR PILOT TRAINING. THE INCREASED MYOPIA IS A SIGNIFICANT PROBLEM FOR THE AF ACADEMY WHICH IS MANDATED TO GRADUATE A MINIMUM NUMBER OF PILOT-QUALIFIED CADETS. ALTHOUGH THE UNDERLYING, MECHANISM FOR THIS INCREASE IN MYOPIA IS UNKNOWN, A MEASURE ...
