STANDARD TOADS CRYSTALS DO NOT PERFORM CONSISTENTLY AT LOW OVERPRESSURES DUE IN PART TO LOW SIGNAL OUTPUT OF THE PZT CRYSTAL AND ALSO DUE TO ELECTRICAL CROSSTALK. WE PROPOSE TO INVESTIGATE TWO TOA TRANSDUCER TYPES THAT ARE PROVEN CONCEPTS IN OTHER APPLICATIONS. WE WILL DESIGN TECHNICIAN FRIENDLY INTERFACES FOR THESE MEASUREMENT SYSTEMS. THE PHASE I DESIGN WILL INTERFACE WITH STANDARD TOADS III REC ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

A METHOD FOR THE EVALUATION AND OPTIMIZATION OF EXPLOSIVE MATERIAL CHARACTERIZATION IS PROPOSED. DAMAGE OF A RIGID RUNWAY CONCRETE SLAB WILL BE OPTIMIZED FOR VARIOUS EXPLOSIVE ENERGY RELEASE RATES. THE STEPS FOR THE PROGRAM ARE: 1) COLLECTION AND EVALUATION OF RUNWAY TEST DAMAGE RESULTS, 2) PRELIMINARY LITERATURE SEARCH FOR APPROPRIATE HYPERGOLIC ENERGY RELEASE RATE, 3) NUMERICAL SIMULATION OF EXP ...

ATA HAS DEVELOPED SEVERAL ANGULAR SENSORS BASED ON THE MAGNETOHYDRODYNAMIC (MHD) PRINCIPLE AND CURRENTLY HOLDS A PATENT ON THE BASIC DESIGN. THE NAVY REQUIRES A PROJECTILE SPIN SENSOR WHICH CAN MEASURE THE PEAK ANGULAR VELOCITY AND INDIRECTLY, THE PROJECTILE MUZZLE VELOCITY. THIS INFORMATION CAN THEN BE USED TO SET CONTROLLED VARIABLE TIME (CVT) FUSES FOR PRECISE PROXIMITY DETONATION. AN MBD ANGUL ...

A VARIETY OF HARDWRE ENHANCEMENTS HAVE BEEN MADE OVER THE YEARS TO THE HIGH ENERGY LASER DATA ACQUISITION AND PROCESSING SYSTEM (HELDAPS) AT THE WHITE SANDS MISSILE RANGE HIGH ENERGY LASER SYSTEM TEST FACILITY. THE EXISTING HELDAPS SOFTWARE DOES NOT FULLY UTILIZE THE CAPABILITIES OF THE ENHANCED SYSTEM CONFIGURATION. A PHASE I PROJECT IS PROPOSED TO SYSTEMATICALLY ANALYZE THE HELDAPS ROCESSING REQ ...

A PROJECT IS PROPOSED TO INVESTIGATE THE FEASIBILITY OF COMBINING A PHASE-CHANGE NON-LINEAR OPTICAL MATERIAL WITH A PHOTOREFRACTIVE MATERIAL IN THIN LAYERS TO ACHIEVE A THREE DIMENSIONAL MASS STORAGE MEDIUM. ORGANIC COMPOUNDS POSSESSING GOOD POLARIZABILITY ALONG WITH COMPOSITION CONDUCIVE TO PHASE CHANGE MECHANICS WILL BE TESTED FOR SHG AND PHASE CHANGE ABILITY, THEN PREPARED IN THIN FILMS ON PHOT ...
