MISSILE SEEKERS MUST DETECT TARGETS IN DUAL BANDS (3-5 UM AND 8-12 UM). THEY NOW USE HYBRID ASSEMBLY OF TWO SEPARATE ARRAYS, WHICH INCREASES THE POWER, CONSUMPTION, THE WEIGHT, AND THE COST. WE WILL DEVELOP MONOLITIHIC DUAL BAND 128X128 STARING ARRAYS ON HGCDTE MATERIAL. THE INNOVATION IS THE DETECTION OF BOTH LONG AND SHORT WAVE SIGNALS IN THE SAME PIXEL SIMULTANEOUSLY. FABRICATION METHODS ARE DE ...

THE EMERGENCE OF VLSI TECHNOLOGY HAS INCREASED THE COMPLEXITY OF INTEGRATED CIRCUIT DEVICES, IN TERMS OF TRANSISTORS PER DEVICE, AT A RATE MULTIPLYING BY 100 EVERY 10 YEARS. NEW TECHNOLOGIES, SUCH AS SURFACE MOUNT, REQUIRE SPECIAL TECHNIQUES TO MAKE THE BOARDS TESTABLE. THE GOAL OF THIS RESEARCH AND DEVELOPMENT PROJECT IS TO REVIEW RELATED RESEARCH AND DEVISE VARIOUS WAYS TO SEMIAUTOMATICALLY ADD ...

PHASE I WILL EXPLORE NOVEL WAYS TO APPLY IMPROVED TECHNIQUES USING THE IEEE/ DOD STANDARD VHSIC HARDWARE DESCRIPTION LANGUAGE (VHDL) TO INTEGRATED ENGINEERING METHODS. IN PARTICULAR, IT WILL ENABLE HARDWARE AND SOFTWARE ENGINEERS TO COLLABORATE SIMULTANEOUSLY DURING DEVELOPMENT OF PARALLEL COMPUTING SYSTEMS. SOME SHORTCOMINGS OF VHDL HAVE BEEN OVERCOME BY THE DARPA QUEST PROJECT WITH DISTRIBUTING ...

THE RESULTS OBTAINED TO DATE BY VARIOUS AUTHORS INDICATE CLEARLY THAT NUMERICAL SOLUTIONS ARE MORE ACCURATE AND REQUIRE LESS COMPUTER TIME AND STORAGE WHEN GRID NODES ARE PROPERLY DISTRIBUTED. THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A NEW METHODOLOGY FOR GENERATING SOLUTION ADAPTIVE GRIDS. OVER THE YEARS IT HAS BEEN ESTABLISHED THAT THE BEST ADAPTIVE STRATEGIES INVOLVE DIRECT CONTROL OVER THE ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO DEVELOP COURSEWARE TO ENHANCE STUDENT UNDERSTANDING OF FLUID DYNAMIC CONCEPTS AND HIS/HER AWARENESS OF COMPLEX PHENOMENA. THE COURSEWARE WILL BE BASED ON AN EXISTING FLUID FLOW MODELING COMPUTER PROGRAM. DEVELOPMENT AND DEMONSTRATION OF ONE CLASSROOM FLUID FLOW EXPERIMENT WILL BE THE SUBJECT OF THE PHASE I WORK.

N/A

A MEASUREMENT INSTRUMENT CAPABLE OF NON-OBTRUSIVELY DETERMINING THE THICKNESS OF A LAYER OF ICE OVER A BODY OF WATER WILL BE DESIGNED AND DEVELOPED. THE INSTRUMENT WILL BE A ONE-PERSON PORTABLE, COMPLETELY SELF-CONTAINED MEASUREMENT SYSTEM. THE INSTRUMENT WILL FEATURE EASE OF MEASUREMENT, VIRTUAL REAL-TIME RESULTS, LOW COST, AND THICKNESS ACCURACY OF +/ONE-HALF INCH. THE OBJECTIVES OF THIS EFFORT ...

IN THIS PROJECT WE PROPOSE TO DEVELOP AN ADVANCED COMPUTATIONAL FLUID DYNAMICS CODE TO AIDE IN THE DESIGN OF HIGHLY LOADED HIGH MACH NUMBER CENTRIFUGAL COMPRESSORS. AN ADVANCED CODE, RAMPANT 1.0, HAS ALREADY BEEN DEVELOPED BY CREARE.X TO PERFORM COMPRESSIBLE FLOW SIMULATIONS IN A WIDE VARIETY OF GEOMETRIC CONFIGURATIONS. THE CODE EMPLOYS UNSTRUCTURED SOLUTION-ADAPTIVE MESHES WITH TETRAHEDRAL CELLS ...

PULSED HIGH VOLTAGE APPLIED TO ELECTRODES IMMERSED IN THE WATER STREAM CREATES HIGH POTENTIAL GRADIENTS IN THE WATER VOLUME BETWEEN THE ELECTRODES. THESE GRADIENTS - OF THE ORDER OF 20 KV/CM, OR MORE - HAVE A BACTERICIDAL ACTION. IN ADDITION, OZONE CAN BE GENERATED THROUGHOUT THE VOLUME BYINTRODUCING AIR IN FINE BUBBLES FROM A SPARGER. THE APPLIED GRADIENTS CREATE OZONE AND CHEMICALLY ACTIVE RADIC ...
