This Small Business Technology Transfer (STTR) Phase I project proposes to develop magneto-optical current and temperature sensors capable of direct integration into power electronic modules, with the design goal of improving reliability and survivability of the power conversion and control circuitry. Existing power electronics designs generally use one of three components to sense current in pow ...

This Small Business Innovation Research (SBIR) Phase I project will develop a fast, reliable and sensitive technology that can identify the nature and the content of the particles in aerosol samples, and provide an early warning of the presence of bio-warfare agents. Current biological agent detection systems rely on point detectors that cannot sample actual aerosol condition in real-time. Additio ...

INTEREST IN GALIUM ARSENIDE (GAAS) INTEGRATED CIRCUITS (IC) GROWING RAPIDLY BECAUSE THEY ARE VERY FASTAND RESISTANT TO RADIATION. HOWEVER, SOME SIGNIFICANT PROBLEMS ARE STILL OF CONCERN. FIRST, THE INCREASED SPEED OF THIS TECHNOLOGY HAS LEAD TO TIMING PROBLEMS IN CIRCUIT DESIGN. WITH THIS TECH- NOLOGY THE GATE SWITCHING SPEEDS HAVE BEEN INCREASED TO WHERE THEY CAN BE EQUIVALENT TO THE WIRE TRANSMI ...

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 ...

This Small Business Innovation Research (SBIR) Phase II project will develop a ceramic hydrogen fuel appliance (CHFA) using ceramic microreactor modules (CMMs) using a low-cost, net-shape manufacturing process, and a new material, that was developed in the Phase I project. The new material developed was demonstrated to have excellent capability for cost-effective microfabri ...

WHEN A BUSINESSMAN OR OTHER DECISION MAKER NEEDS AN ESTIMATE (SAY, OF SALES OF A NEW INDUSTRIAL PRODUCT), AND HEHAS ACCESS TO RICH AND VARIED INFORMATION, BUT LIMITED RESOURCES HE NORMALLY MAKES HEAVY USE OF JUDGEMENT IN HIS ENQUIRY. PERSONALIST (BAYESIAN) STATISTICS PROVIDES A LOGICAL FRAMEWORK TO GUIDE THE USE OF SUCH JUDGMENT, IN CONJUNCTION WITH ANY SAMPLE OR OTHER DATA. IN PARTICULAR, IT PROD ...

MANY DIVERSE METHODS OF KNOWLEDGE REPRESENTATION HAVE BEEN USED BY AI RESEARCHERS. NONE APPEAR POWERFUL ENOUGH TO CAPTURE THE DIVERSE TYPES OF KNOWLEDGE THAT PEOPLE POSSESS NOR DO THEY APPEAR FLEXIBLE ENOUGH TO SUPPORT THE ACQUISITION OF KNOWLEDGE. THE PROPOSED PROJECT WILL DEVELOP A KNOWLEDGE REPRESENTATION SCHEME THAT INTEGRATES THREE MAJOR FRAMEWORKS: SCHEMAS/FRAMES, PRODUCTION RULES AND MENTAL ...
