AER PROPOSES TO DEVELOP A NEW CONCEPT IN PROVIDING WEATHER \FORECASTING FOR INDUSTRY, MADE POSSIBLE BY THE DECREASING COSTS OF POWERFUL COMPUTERS. IMPROVED SHORT-RANGE FORECASTS WOULD BE OBTAINED BY RUNNING A MODEL ON THE USER'S COMPUTER. THE MODEL WOULD ACCESS THE FORECASTS OF THE NATIONAL METEROLOGICAL CENTER AND MODIFY THEM THROUGH A DETAILED SIMULATION OF THE PHYSICS OF ATMOSPHERIC PROCESSES,T ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP DATA COMPRESSIONTECHNIQUES USED TO COMPRESS DIGITAL ENVIRONMENTAL SATELLITE DATA FROM THE NATIONAL CLIMATIC DATA CENTER (NCDC) ARCHIVES SUCH THAT THE RESULTING DATA CAN BE READILY USED WITHIN THE LIMITED RESOURCES OF PC/AT SYSTEMS. THE JOINT PHOTOGRAPHIC EXPERTS GROUP (JPEG) HAS DEVELOPED ANINTERNATIONAL STANDARD FOR THE COMPRESSION OF CONTINUOUS TONE DI ...

DETERMINATION OF URANIUM IN THE URINE OF WORKERS IS REQUIRED BY THE NRC AT NUCLEAR FACILITIES. EXTREMELY LOW CONCENTRATIONS OF URANIUM, ESPECIALLY IN SMALL SAMPLES, ARE DIFFICULT TO MEASURE USING EXISTING TECHNOLOGY. FUTURE NRC PLANS TO CHARACTERIZE BIOAVAILABLE URANIUM FRACTIONS COMPRISING THE URANIUM BODY BURDEN WILL REQUIRE EVEN HIGHER SENSITIVITIES. HIGH SENSITIVITY TECHNOLOGY DEVELOPED FOR UR ...

FIBER REINFORCED POLYMERIC COMPOSITES CAN REDUCE WEIGHT, INCREASE CRASHWORTHINESS, AND REDUCE CORROSION RELATIVE TO METALS. HOWEVER, LOW COST MANUFACTURING APPROACHES ARE NEEDED IN ORDER FOR THESE MATERIALS TO BE COMPETITIVE IN HIGH VOLUME AUTOMOTIVE APPLICATIONS. LIQUID COMPOSITE MOLDING (LCM) IS RECOGNIZED AS A PROMISING METHOD FOR RAPID, LOW COST FABRICATION. LOW COST, COMPLEX PREFORMS ARE NEED ...

STEAM GENERATOR TUBES REPRESENT A UNIQUE PART OF THE REACTOR COOLANT SYSTEM (RCS). LEAKAGE FROM ANY OTHER PART OF THE RCS IS CAPTURED BY THE CONTAINMENT BUILDING, BUT STEAM GENERATOR TUBE LEAKAGE IS TRANSPORTED OUT OF THE CONTAINMENT BUILDING ALONG WITH THE STEAM, WHICH IS NORMALLY UNCONTAMINATED. STEAM GENERATOR TUBES, CONSEQUENTLY, DESERVE, AND RECEIVE SPECIAL CONSIDERATION. THE ASSURANCE OF STE ...

ON FEBRUARY 9, 1991, AT THE MIHAMA UNIT 2 NUCLEAR POWER STATION, OPEARTED BY KANSAI ELECTRIC CORPORATION, A STEAM GENERATOR TUBE RUPTURED AND RELEASED APPROXIMATELY 9,000 GALLONS OF REACTOR COOLANT INTO THE SECONDARY SYSTEM. THE LEAKAGE CAUSED A RAPID DEPRESSURIZATION OF THE REACTOR COOLANT SYSTEM, WHICH RESULTED IN AN AUTOMATIC REACTOR TRIP AND ACTUATION OF THE HIGH PRESSURE SAFETY INJECTION SYST ...

BOVINE PANCREATIC RIBONUCLEASE A (RNASE A) IS A MODEL SYSTEMFOR ESTABLISHING RULES THAT GOVERN PROTEIN STABILITY AND FOLDING. BY LEARNING AND APPLYING THESE RULES, MORE ROBUST ENZYMES OF VARIOUS TYPES COULD BE DESIGNED FOR COMMERCIAL APPLICATIONS. SYNTHESIS, CLONING AND EXPRESSION IN BACILLUSSUBTILIS OF A GENE ENCODING RNASE A WILL ALLOW FOR THE ECONOMICAL PRODUCTION OF VARIANT PROTEINS WHICH ARE ...

THE PRIMARY OBJECTIVE OF THIS PROPOSAL IS TO DESIGN AND BUILD A SYSTEM FOR FISHERY AND MARINE MAMMAL STOCK PREDICTION USING NONLINEAR SPATIO-TEMPORAL NEURAL NETWORK THEORY. WHILE THE CENTRAL ENGINE OF THE SYSTEM MAKES USE OFNONLINEAR NEURAL NETWORKS FOR PREDICTION, SEVERAL PERIPHERAL MODULES INCORPORATED IN THE DESIGN ASSIST THE USER IN EMPLOYING THE PREDICTOR FOR VARIOUS APPLICATIONS. IN PARTICUL ...
