APPLIED TECHNOLOGY ASSOCIATES, INC., (ATA) DESIGNED, FABRICATED, AND PERFORMED AN INITIAL TEST OF A DEVICE WHICH REPRESENTS A NEW CONCEPT FOR AN INERTIAL, ANGULAR RATE SENSOR. THE SENSOR UTILIZES A MERCURY PROOF MASS WHOSE ANGULAR RATE IS DETERMINED FROM THE VOLTAGE GENERATED AS THE MERCURY MOVES THROUGH A MAGNETIC FIELD. THE DEVICE HAS NO PRECISION PARTS NOR MOVING PARTS EXCEPT LIQUID MERCURY. TH ...

COMPUTATIONAL ALGORITHMS AND CODE WILL BE DEVELOPED FOR CALCULATING UNSTEADY COMPRESIBLE 3-D VISCOUS FLOW AND RETREATING-BLADE DYNAMIC STALL ON MODERN HIGH-PERFORMANCE HELIOPTER ROTORS. THE ALGORITHM DEVELOPMENT WILL START FROM AN EXISTING 3-D TIME DEPENDENT VISCOUS COMPRESSIBLE CODE ALREADY USED SUCCESSFULLY TO CALCULATE PERIODIC PITCHING OF A SWEPT WING SECTION MOUNTED IN A WIND TUNNEL TEST SECT ...

AN INVESTIGATION OF WIRE ANTENNAS IS PROPOSED TO DETERMINE AN OPTIMAL CONFIGURATION FOR A ULTRA-WIDEBAND ANTENNA. A NEW ANTENNA, THE BALANCED TRANSMISSION-LINE WAVE ANTENNA, HAS BEEN DEMONSTRATED TO HAVE DESIRABLE CHARACTERISTICS AT LOWER FREQUENCIES. IT IS PROPOSED TO EXAMINE THE FEASIBILITY OF THIS ANTENNA AT HIGHER FREQUENCIES.

UREASE OFFERS DISTINCT ADVANTAGES OVER OTHER ENZYMES FOR PREPARATION OF CONJUGATES USED IN ENZYME-LINKED IMMUNO-SORBENT ASSAY SYSTEMS. MOLECULAR DEVICES CORPORATION (MENLO PARK, CA) HAS CAPITALIZED ON THESE ADVANTAGES IN THEIR THRESHOLD SYSTEM. THIS IMPRESSIVE SYSTEM UTILIZES AVIDIN-BIOTIN TO "CAPTURE" ANALYTE-BOUND ANTIBODY-UREASE CONJUGATE COMPLEXES ONTO A MEMBRANE, WHERE THEY ARE QUANTITATED BY ...

KTECH PROPOSES TO DEVELOP OPTICAL HOPKINSON BAR PRESSURE GAUGES FOR MEASUREMENT OF AIRBLAST ON UNDERGROUND NUCLEAR EVENTS. THE BARS WILL BE MADE OF SINGLE CRYSTAL SAPPHIRE WHICH HAS A MEASURED YIELD STRENGTH IN EXCESS OF 10 GPA. THESE GAUGES WILL HAVE A RISE TIME OF ABOUT 2 US OF DATA. DURING PHASE I, WE WILL CONSTRUCT AND CALIBRATE A STRESS-INDUCED BIREFRINGENCE GAUGE (SIBG) WHICH WOULD NEED NO E ...

UNDER THIS EFFORT, WE WILL DEVELOP A PORTABLE MEMORY TESTER UNIQUELY DESIGNED TO PERFORM THE TYPES OF TESTS REQUIRED FOR RADIATION EFFECTS CHARACTERIZATION. SPECIFICALLY, IT WILL PERFORM TESTS TO CHARATERIZE SINGLE EVENT PHENOMENA (SEP), TOTAL DOSE IONIZING EFFECTS, DOSE RATE, AND RAPID ANNEALING PHENOMENA. IT WILL COMBINE KEY FEATURES OF GENERAL PURPOSE ASIC TESTERS AND DEDICATED MEMORY TESTERS R ...

THE PROPOSED RESEARCH IS TO INTEGRATE A NUMBER OF ARMOR DESIGN AND EVALUATION MODELS INTO A MODERN COMPUTING ENVIRONMENT HOSTED BY A DEDICATED WORKSTATION. THE EVENTUAL PRODUCT WILL UTILIZE A GRAPHICAL USER INTERFACE, INTERACTIVE GRAPHICS, NETWORKING, AND SO FORTH, TO PROVIDE A MORE PRODUCTIVE COMPUTING ENVIRONMENT FOR THE ARMOR DESIGNER AND ANALYST. THE PHASE I GOALS ARE TO DEVELOP A HARDWARE/SOF ...

LOW-ENERGY LASER TECHNOLOGY HAS THE POTENTIAL TO SIGNIFICANTLY IMPROVE THE EFFENCIENCY AND EFFECTIVENESS OF NUCLEAR WEAPONS SECURITY OPERATIONS. SUCH LASERS, EMPLOYED IN EITHER AUTOMATED OR REMOTELY MANNED CONFIGURATIONS, CAN SUPPLEMENT CURRENT PHYSICAL SECURITY MEASURES BY PROVIDING THREE NON-LETHAL RESPONSE OPTIONS: (1) WARN INTRUDERS THAT THEY HAVE BEEN DETECTED AND ARE ENTERING A SECURE AREA, ...
