THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

GEOPHEX, LTD. PROPOSES TO DEVELOP AN AIRBORNE ELECTROMAGNETIC (AEM) SYSTEM DEDICATED TO THE DETECTION OF SUBMARINES IN THE OCEAN (TOPIC NO. N87-22, THE DOD SBIR PROGRAM, 1987). THE AEM METHOD HAS RECENTLY EMERGED AS A VIABLE TECHNIQUE FOR AIRBORNE CHARTING OF WATER DEPTH (IN EXCESS OF PERHAPS 100 M), WATER CONDUCTIVITY (THUS, SALINITY AND TEMPERATURE VARIATIONS), AND BOTTOM SEDIMENT CONDUCTIVITY ( ...

CURRENT BEST TELEMETRY SOURCE COMBINER SYSTEMS USED AT WEAPONS TEST RANGES ARE CAPABLE OF SELECTING THE "BEST" SIGNAL FROM SEVERAL REDUNDANT SOURCES. HIGHER DATA RATES AND DETERIORATION OF TEST RANGE SNRS HAVE PRECIPITATED A REQUIREMENT FOR AN AUTOMATED TELEMETRY SIGNAL PROCESSING SYSTEM CAPABLE OF COMBINING AVAILABLE SOURCES INTO AN ENHANCED "BEST SIGNAL."

CERTAIN SUBSTANCES EXHIBIT NONLINEAR RESPONSES TO THERMAL GRADIENTS APPLIED ACROSS THEM. IN PARTICULAR, CERTAIN COMPOUNDS OF THE IIIA/VA GROUPS EXHIBIT UNIDIRECTIONAL RESPONSES TO THERMAL FLUX, WHERE THE CTE DIFFERS BETWEEN XAND Y-, OR XAND ZAXES. WE PROPOSE TO USE A COMPOSITE MATRIX OF TWO DIFFERENT MATERIALS SANDWICHED INTO A SMALL CROSS-SECTIONAL AREA, TO ACT AGAINST THE NORMAL THERMAL GRADIENT ...

THE OBJECTIVE OF THE STUDY EFFORT IS TO PRODUCE COMPLETE SPECIFICATIONS, A DETAILED DESIGN, AND PERFORMANCE CALCULATIONS FOR A 'FREQUENCY-STEPPED' GROUND PENETRATING RADAR (GPR) SYSTEM. THE FREQUENCY STEPPED APPROACH WILL ALLOW IMPROVEMENTS OVER THE TYPICAL 'SHORT-PULSE' RADAR BY IMPROVING BANDWIDTH CONTROL, IMPEDANCE MISMATCH COMPENSATION, HIGHER OUTPUT POWER, AND COHERENT INTEGRATION AND IMAGE P ...
