THE PROPOSED FIBLOC SENSOR PROVIDES AN ECONOMIC MEANS TO PROTECT, LITERALLY, MILES OF A PREFERRED PERIMETER REGION AGAINST UNAUTHORIZED INTRUSIONS. THE OPTICAL FIBERS EMPLOYED INT HE FIBLOC SENSOR PROPAGATE CW OR PULSED INFRARED LIGHT SIGNALS WHOSE TRANSMISSION AND/OR REFLECTION SENSITIVITY IS AFFECTED BY MECHANICAL PRESSURE SUCH AS WOULD BE PRODUCED BY THE DISTENSION OF SURFACED MOUNTED FIBERS AL ...

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 ...

THE PHASE I EXPERIMENTAL EFFORT WILL DEMONSTRATE THE FEASIBILITY OF A FIELD WORTHY GROUND MOTION SENSOR TO REPLACE PIEZO-ELECTRIC ACCELEROMETERS FOR CONVENTIONAL EXPLOSIVES AND NUCLEAR TESTING. THE OUTPUT SIGNALS OF PIEZO-ELECTRIC ACCELEROMETERS MUST BE INTEGRATED TWICE TO DETERMINE GROUND MOTIONS. THIS PROCESS REDUCES SYSTEM ACCURACY AND MEASUREMENT BANDWIDTH. ADDITIONALLY, AS PIEZO-ELECTRIC SENS ...

CREATION OF BURIED INSULATING LAYERS IN SILICON WAFERS BY HIGH DOSE OXYGEN IMPLANTATION (SIMOX) HAS GAINED SIGNIFICANT ATTENTION IN THE LAST TWO YEARS. THE SIMOX TECHNOLOGY IS POSITIONED TO BE A PRIME CONTENDER IN THE SILICON-ON-INSULATOR (SOI) ARENA MAINLY BECAUSE OF THE INHERENT RELIABILITY/REPRODUCIBILITY OF THE ION IMPLANTATION TECHNOLOGY. ONE OBSTACLE TO BROADER USE OF THE SIMOX MATERIAL IS T ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN IMPROVED DIFFERENTIAL PRESSURE GAGE FOR DETERMINING DYNAMIC PRESSURE WITHIN BLAST AND SHOCK WAVE FLOWS WHERE THE FLOWS ARE SUBSONIC. DERIVATION OF DYNAMIC PRESSURE FROM A MEASUREMENT OF THE DIFFERENCE BETWEEN STAGNATION PRESSURE AND SIDE-ON OR STATIC PRESSURE REQUIRES USE OF THE SIDE-ON PRESSURE RECORD TO CORRECT FOR COMPRESSIBILITY EFFECTS. CURRENTLY ...

WE PROPOSE TO APPLY ARTIFICIAL NEURAL NETWORKS TO THE DERIVATION OF CLOUD MOTION VECTORS FROM SATELLITE IMAGERY. IN PHASE I, WE WILL CONCENTRATE ON USING A NEURAL NETWORK IN THE FIRST STEP IN THE DERIVATIO OF CLOUD MOTION VECTORS, THE HEIGHT ASSIGNMENT AND TARGET SELECTION. THE NEURAL NETWORK COMBINES, AT EACH IMAGE PIXEL, BRIGHTNESS IN DIFFERENT CHANNELS TO DETERMINE CLOUD TYPE AND LEVEL (I.E., L ...

Aspen Systems proposes to develop high dielectric constant (K), low loss tellurium polymers to meet the design objectives of high energy density capacitors. In the proposed Phase I program we will apply rigorous computational chemical techniques to predict the properties of this new class of polymers. We will attempt the synthesis of the parent polymer of the tellurium family, fabricate films for ...
