INFORMATION USE HAS BEEN IDENTIFIED AS A KEY FACTOR IN ENHANCING COMPETITIVENESS OF THE NATION'S INDUSTRIES. THE RESEARCH PROPOSED WOULD RIGOROUSLY EVALUATE CURRENT IMPEDIMENTS TO EFFECTIVE USE, DEFINE POTENTIAL ECONOMIC VALUE OF ENHANCED USE, AND EXPLORE THE OPPORTUNITY FOR COMPUTERIZED DECISION AIDS TO INCREASE INFORMATION EFFECTIVENESS IN DECISIONMAKING. THESE GOALS WOULD BE INVESTIGATED FOR TH ...

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 ...

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 ...

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 ...

THE RESEARCH EFFORT IS DIRECTED TOWARDS DETERMING THE TECHNICAL FEASIBILITY OF MORPHOLOGICALLY INVARIENT ELECTRODE/SOLID POLYMER ELECTROLYTE (SPE) JUNCTIONS FOR LONGCYCLE LIFE ELECTROCHEMICAL CELLS. ALKALI ION CONDUCTING SPES TO BE USED IN THIS PROGRAM WILL INCLUDE THOSE BASED UPON POLY(ETHYLENE OXIDE) AND THE POLYPHOSPHAZENES. NOVEL SECONDARY ELECTRODES WILL INCLUDE THE LITHIUM INTERCALATING MATE ...

TECHNICAL EFFORT IS DIRECTED TOWARDS DETERMING THE FEASIBILITY OF AN ELECTROCHEMICALLY REVERSIBLE LIQUID NEGATIVE ACTIVE MATERIAL CONSISTING OF LITHIUM DISSOLVED IN LIQUID AMMONIA TO GIVE A NOVEL SOLVATED ELECTRON SECONDARY LITHIUM ELECTRODE. CONTAINMENT OF THE ACTIVE MATERIAL FROM DIRECT CONTACT TO THE LIQUID NON-AQUEOUS ELECTROLYTE IS REALIZED VIA USE OF A LITHIUM INTERCALATED ELECTRONICALLY CON ...
