CONTINUOUS, FULL POWER OPERATION OF HIGH OUTPUT SEMICONDUCTOR DEVICES IS GENERALLY LIMITED BY THE HEAT DISSIPATION CAPABILITY OF THE DEVICE PACKAGE. EXISTING COOLING SCHEMES REQUIRE COOLING PUMPS AND SECONDARY RADIATORS, WHICH LIMITS THE APPLICATION OF THESE DEVICES TO LARGE VEHICLES. THIS PROPOSAL CONCERNS THE ANALYSIS AND DESIGN OF A THERMAL PACKAGE WHICH IS CAPABLE OF DISSIPATING HIGH HEAT FLUX ...

DESIGN AND FABRICATION OF SOLID-STATE DIRECTION-INDICATING APPARATUS, WITH TILT-IMMUNITY, THAT PROVIDES AN AUDIBLE OR TACTILE INTERFACE WITH THE USER. REDUCED SIZE TO ALLOW ENCAPSULATION IN A TYPICAL WALKING CANE. A DEVICE WILL BE DESIGNED THAT WILL PROVIDE A VISUALLY IMPAIRED PERSON WITH AN INDICATION OF HORIZONTAL DIRECTION, WITH RESPECT TO THE EARTH'S MAGNETIC FIELD. THE DEVICE WILLALSO SIGNAL ...

WE PROPOSE TO DEVELOP AND VERIFY IN THIS PHASE I PROGRAM A TECHNIQUE THAT WILL ACCURATELY AND REPEATABLY MEASURE SURFACE PROFILES AND DISTANCES BETWEEN A TEST OBJECT AND DETECTORS USING THE SHEARING HETERODYNE INTERFEROMETRY TECHNIQUE. THE TECHNIQUE IS BASED ON SHEARING HETERODYNE INTERFEROMETRY WITH A FREQUENCY MODULATED LASER DIODE USING THE FOUR-BUCKET-INTEGRATING TECHNIQUE. IT CAN BE USED TO D ...

WE PROPOSE IN PHASE I TO DEMONSTRATE, USING AVAILABLE TECHNOLOGY AND RESOURCES, THE FEASIBILITY OF A "PHOTON-GUN" DEMONSTRATOR CONCEPT THAT COMBINES THE INDUCED-DIPOLE STORAGE LASER CONCEPT PIONEERED BY THE SOVIETS IN THE EARLY 1970'S WITH STATE-OF-THE-ART TRAVELING WAVE (OR LASER) INDUCED PULSE EXTRACTION AND THE TRADITIONAL HARDWARE DESIGN STRUCTURE OF AN IDENTIFIABLE PROJECTILE/CARTRIDGE/LAUNCH ...

N/A

IN PHASE I, A SYSTEMATIC AND COMPLETE INVESTIGATION ON THE SYNTHESIS OF CADMIUM SULFIDE WILL BE CONDUCTED. CADMIUM SULFIDE (CDS) WILL BE SYNTHESIZED BY TWO METHODS: 1. SPONTANEOUS REACTION BETWEEN DIMETHYLCADMIUM AND HYDROGEN SULFIDE, AND 2. REACTION OF CADMIUM AND SULFUR ELEMENTS BY VAPOR DEPOSITION. THE CDS POWDER OBTAINED FROM THESE TWO TECHNIQUES WILL BE HEAT-TREATED BY BAKING OUT AT ELEVATED ...

N/A

THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP IMPROVED DETECTION AND CLASSIFICATION ALGORITHMS FOR TACTICAL AIRBORNE MILLIMETER WAVE (MMW) SEEKERS EMPLOYING POLARIMETRIC PROCESSING. THE PROPOSED RESEARCH IS BASED UPON NONCOHERENT TARGET INFORMATION (NTI) FEATURES (1) EXTRACTION BY WIDEBAND CIRCULAR POLARIZATION DUAL-CHANNEL ACTIVE MMW SEEKERS. THE NTI FEATURES ARE NEAR-COMPLETE IN TARGET INFORMATIO ...

THE OBJECTIVE OF THIS EFFORT IS TO EXPLORE THE FEASIBILITY OF DEVELOPING AN ADVANCED COMPUTER-BASED TOOL THAT WILL ENHANCE GOVERNMENT AND CONTRACTOR CONTROL OF THE SOFTWARE DEVELOPMENT PROCESS. THIS TOOL WILL ENHANCE THE DEVELOPMENT OF QUALITY SOFTWARE THROUGH THE USE OF CLEAR CONTRACTURAL DEFINITION OF QUALITY MEASURES AND THE USE OF SOFTWARE TOOLS TO MEASURE SOFTWARE QUALITY. THE TOOL WILL COVER ...
