LIGHT WEIGHT, HIGH ENERGY CHARGED PARTICLE BEAM PRODUCTION IS FEASIBILE WHEN THE ACCELERATION POTENTIAL IS GENERATED FROM AN INDUCTIVE ENERGY STORAGE SYSTEM. AN INTENSIVE, COPIOUS X-RAY RADIATION SOURCE IS THEREFORE OBTAINABLE SIMULTANEOUSLY THROUGH THE HIGH-CURRENT ELECTRON BEAM AND METAL TARGET INTERACTION. USE OF A PLASMA OPENING SWITCH IS PROPOSED FOR OPENING THE INDUCTIVE CIRCUIT BECAUSE IT I ...

THE INTELLIGENT PROCESSING OF MATERIALS IS A NOVEL CONCEPT IN MATERIALS PROCESSING IN WHICH INFORMATION FROM REAL TIME, IN-SITU MICROSTRUCTURAL SENSORS AND PROCESS MODELS ARE COMBINED WITH ARTIFICIAL INTELLIGENCE APPROACHES TO CONTROL A MATERIALS PROCESS. THE INSITU SENSORS ARE A KEY TO THIS TECHNOLOGY SINCE INFORMATION ABOUT THE "STATE" OF THE MATERIAL MUST BE ASCERTAINED. THEREFORE, THIS PROPOSA ...

THIS PHASE I EFFORT WILL APPLY THEORETICAL METHODS BASED PRINCIPALLY ON CAGNIARD'S FORMALISM (PREVIOUSLY INCORPORATED BY US INTO OUR POWERFUL SWREF CODE), TO THE PROPAGATION AND FOCUSING, IN BOTH REFLECTIVE AND PHASED-ARRAY EQUIPMENT, OF SHOCK-WAVES PRODUCED BY UNDERWATER SPARKS. THE OBJECTIVE IS TO INVESTIGATE AND PROVIDE DESIGN DATA FOR LITHOTRIPSY EQUIPMENT IN WHICH FOCUSED SHOCK WAVES ARE USED ...

THE SERVICEABILITY LIMIT STATE ASSOCIATED WITH OCCUPANT COMFORT UNDER WIND INDUCED LATERAL AND TORSIONAL MOTION IS BECOMING AN INCREASINGLY IMPORTANT CONSIDERATION IN THE DESIGN OF TALL BUILDINGS. IN SOME INSTANCES, STRUCTURAL MODIFICATIONS REQUIRED TO PRODUCE ACCEPTABLE PREDICTED RESPONSE CHARACTERISTICS CAN COST HUNDREDS OF THOUSANDS OF DOLLARS OR EVEN MILLIONS OF DOLLARS. WITH THESE KINDS OF CO ...

THIS STUDY UNDERTAKES AN ASSESSMENT OF THE MILITARY MARKET FOR APPLICATIONS OF AN OXYGEN EXTRACTION TECHNOLOGY BEING DEVELOPED BY DARPA AT THE AQUANAUTICS CORPORATION. THE POTENTIAL APPLICATIONS IDENTIFIED THROUGH A LITERATURE SEARCH AND TECHNICAL DISCUSSIONS WITH DEVELOPING AGENCIES ARE SUBJECTED TO AN OPERATIONAL, TECHNICAL, AND ECONOMIC FEASIBILITY ANALYSIS TO DETERMINE WHICH APPLICATIONS HAVE ...

THE DIGITAL SIGNAL PROCESSING (DSP) INDUSTRY SUPPLIES ESSENTIAL TOOLS AND TECHNOLOGY TO A HOST OF DEFENSE AND CIVILIAN END-USERS. DSP PRODUCTS ARE FOUND IN MANY FIELDS INCLUDING COMMUNICATIONS, AUDIO, VIDEO, AUTOMATION, GEOPHYSICAL, MEDICAL, AND RADAR/SONAR APPLICATIONS. HOWEVER, MANY CRITICALLY IMPORTANT PROBLEMS CANNOT BE SERVEDBY THIS INDUSTRY DUE TO CURRENT COMPUTATIONAL LIMITATIONS OFDSP HARD ...

RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

WHILE THE NATION'S ECONOMIC AND SOCIAL WELL-BEING CONTINUES TO BECOME INCREASINGLY DEPENDENT ON THE NATION'S ELECTRIC ENERGY SYSTEMS, CONTINUED RELIABLE PERFORMANCE OF THOSE SYSTEMS MUST BE MAINTAINED DESPITE INCREASING FINANCIAL AND OPERATING CONSTRAINTS. THE TASK OF MAINTAINING ACCEPTABLE LEVELS OF RELIABILITY IS MADE INCREASINGLY DIFFICULT BY THE LACK OF ANALYTICAL TOOLS FOR RELIABILITY EVALUAT ...

SECURITY CONTROL OF POWER SYSTEMS INVOLVES THE MONITORING OFTHE SYSTEM STATE, THE EVALUATION OF SYSTEM VULNERABILITY TO POTENTIAL DISTURBANCES, AND CONTROL ACTION CALCULATED TO CONSTRAIN THAT VULNERABILITY TO AN ACCEPTABLE LOW VALUE. BECAUSE OF THE PERVASIVE UNCERTAINTIES IN THIS PROBLEM, SECURITY CONTROL IN PRACTICE HAS BEEN RESTRICTED TO EMPIRICAL, SOMETIMES INTUITIVE PROCEDURES, SUPPORTED AT BE ...

CONVENTIONAL GAS-FIRED COOKING RANGES HAVE LOW OVERALL THERMAL COOKING EFFICIENCY, WASTING APPROXIMATELY HALF OF THE COMBUSTION ENERGY. FURTHER, COOKING IMPLEMENTS HAVE BEEN IDENTIFIED AS A MAJOR SOURCE OF THE INDOOR AIR POLLUTANTS NO2 AND CO. THE PURPOSE OF THE RESEARCH PROPOSEDHEREIN IS TO CONSTRUCT A WORKING PROTOTYPE OF A CATALYTIC INFRARED GAS BURNER SUITABLE FOR COMMERCIAL AND DOMESTIC COOKI ...
