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 ...

THIS PROJECT ADDRESSES SYSTEMS TO REDUCE NOISE AND VIBRATIONS EMANATING FROM AUXILIAIY POWER UNITS (APUS) WHICH ARE BEING INITEGRATED INTO ARMY VEHICLES AND SHELTERS. EXCESSIVE NOISE AND VIBRATIONS ARE HARMFUL TO AND HINDER THE EFFECTIVENESS OF OPERATORS AND OCCUPANTS. IN MILITARY EQUIPMENT, IT IS ALSO BENEFICIAL TO AVOID EMANATIONS THAT MIGHT BE USED AS DETECTION SIGNATURES . THIS EXPLORATORY DEV ...

CHROMEX HAS DEMONSTRATED CCD ARRAY DETECTOR-BASED RAMAN SPECTROSCOPY EMPLOYING LASER DIODES AND OPTICAL FIBER PROBES CAPABLE OF SENSITIVITIES COMPARABLE TO OR BETTER THAN THE FOURIER TRANSFORM RAMAN (FTR) METHOD. IT IS LIKELY THIS NEW METHOD CAN BE IMPLEMENTED IN A RUGGED COMPACT INSTRUMENT HAVING NO MOVING PARTS, IN A PACKAGE OF LESS THAN 1 FT.3, WEIGHING LESS THAN 50 POUNDS, AND REQUIRING LESS T ...

THIS EFFORT IS TO DETERMINE THE DESIGN OF A DIODE-PUMPED SOLID-STATE 2 UM COHERENT LASER RADAR FOR THE HIGH SPATIAL AND TEMPORAL RESOLUTION MEASUREMENT OF WIND VELOCITY AND WATER VAPOR CONCENTRATIONS IN THE ATMOSPHERIC BOUNDARY LAYER. A DETAILED COMPUTER SIMULATION OF THE COHERENT LASER RADAR WIND AND DIAL MEASUREMENT PROCESS WILL BE USED TO DETERMINE SYSTEM DESIGN PARAMETERS. A PERFORMANCE TRADE ...

THE INDIVIDUALS WITH DISABLILTIES EDUCATION ACT REQUIRES TRANSITION PLANNING, RELATED INSTRUCTION AND INTERAGENCY COORDINATION FOR ALL SPECIAL EDUCATION STUDENTS. THE MOVEMENT FROM SCHOOL TO POST-SCHOOL ACTIVITIES IS AN IMPORTANT EVENT IN TERMS OF THE INFORMATION WHICH CAN BE CAPTURED AND ANALYZED. SPECIFICALLY, THE EMPLOYMENT HISTORY OF DISABLED INDIVIDUALS HAS BEEN A CONCERN NOTED IN A NUMBER OF ...

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.

CABLE SHIELDS ARE AN IMPORTANT ASPECT OF THE HARDENING OF SYSTEMS TO ELECTRO- MAGNETIC ENVIRONMENTS. THE INTEGRITY OF THESE SHIELDS IS VERY OFTEN CRUCIAL TO THE SURVIVAL OF A CRITICAL SYSTEM TO AN EMF ENVIRONMENT, FOR EXAMPLE. BECAUSE CABLE SHIELD INTEGRITY IS FREQUENCY DIFFICULT TO DETERMINE VISUALLY, AN ALTERNATIVE SIMPLE APPROACH IS REQUIRED. THE OBJECTIVE OF THE PROPOSED WORK IS TO DEVELOP A P ...
