CONTRACTOR WILL DEVELOP A LAGRANGIAN FORMULATION FOR THE ELECTROMAGNETIC RESPONSE OF A METALLIC ENCLOSURE WITH THIN, SLIGHTLY DIFFUSIVE WALLS AND A WIRE SPANNING THE ENCLOSURE. CONTRACTOR WILL FIRST DERIVE A LAGRANGIAN OPERATOR ON THE FIELDS WHICH IS STATIONARY WHEN MAXWELL'S EQUATIONS ARE SATISFIED. THE LAGRANGIAN WILL THEN BE USED TO DETERMINE THE ENCLOSURE EIGENMODES (WIRE INCLUDED) AND THE AMP ...

CODES CURRENTLY EXIST THAT WILL CALCULATE THE ELECTROMAGNETIC ENVIRONMENT (EMP) PRODUCED BY A BEAM OF COLLIMATED GAMMA RAYS. THE COLLIMATION MAY BE EITHER CYLINDRICAL OR CONICAL. THE CURRENT EFFORT WILL BE TO INSTALL THE CODES ON AN ARMY CRAY COMPUTER AND TO SET THEM UP AND RUN THEM FOR PROBLEMS OF INTEREST TO THE ARMY.

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

ALTHOUGH TECHNOLOGY IS ADVANCING AT AN EVER INCREASING PACE,ITS APPLICATION FOR USE BY HANDICAPPED INDIVIDUALS HAS BEEN SLOW. SEVERELY IMPAIRED INDIVIDUALS OFTEN REQUIRE SOME TYPE OF "HIGH TECHNOLOGY" MEANS TO ENABLE THEM TO HAVE A DEGREE OF MOBILITY. THE SPECIFIC AIM OF THIS PROGRAM IS TO INVESTIGATE THE POTENTIAL OF USING ELECTRO-OPTICS AS A MEANS FOR THE HANDICAPPED TO EFFECT CONTROL OF HIS/HER ...

N/A

CURRENT 3-D ANIMATION TECHNIQUES INVOLVES SIMPLE SHOWING SEPARATELY PREPARED IMAGES IN A SEQUENCE. THESE TECHNIQUES ARE SOMETIMES CALLED REPEAT-STATIC TECHNIQUES BECAUSE THEY MAKE NO USE OF THE SIMILARITY BETWEEN THE SUCCESSIVE IMAGES IN THE PREPARATION OF THE IMAGES. FOR REALISTIC ANIMATION REQUIRING THOUSANDS OF FRAMES, THE COMPUTATIONAL COST CAN BE PROHIBITIVE, AND THE TURN-AROUND TIME UNACCEPT ...

N/A

A PROPOSED HIGH TEMPERATURE THERMOCOUPLE CALIBRATOR FOR USE IN FLOWING GAS STREAMS COMPRISES THREE SUBSYSTEMS: (A) A HOT GAS GENERATOR USING A PLASMA GENERATOR OR FLAT FLAME BURNER AS THE HEAT SOURCE; (B) A LASER DOPPLER VELOCIMETRY SYSTEM FOR MEASURING VELOCITY COMPONENTS IN THE NEIGHBORHOOD OF THE TEST PROBE; (C) A COMPUTERCONTROLLED TEMPERATURE MEASUREMENT SYSTEM THAT COMBINES SPECTROSCOPIC (PL ...

LARGE QUANTITIES OF TOXIC HYDROGEN CHLORIDE (HCL) GAS ARE EMITTED DURING SOME MISSILE LAUNCHES, POSING A SERIOUS SAFETY HAZARD TO LAUCH SITE PERSONNEL. EXISTING INSTRUMENTATION FOR MEASURING HCL CONCENTRATIONS DOES NOT HAVE ADEQUATE TIME RESPONSE OR SENSITIVITY, AND IS SUSCEPTIBLE TO INTERFERENCES FROM OTHER MISSILE EXHAUST GASES. WE PROPOSE A NEW INSTRUMENTATION CONCEPT FOR LAUNCH SITE MEASURMENT ...
