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 ...

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 ...

ACOUSTIC FIELDS CAN BE DESIGNED TO COAX LIQUID BORNE SUBMICRONIC PARTICLES TO ANNOUNCE THEIR PRESENCE LOUDER THAN THE USUAL SCATTERING SIGNALS WHICH ARE PRIMARILY DETERMINED BY THE DENSITY AND COMPRESSIBILITY CONTRAST BETWEEN THE PARTICLE MATERIAL AND THE HOST FLUID. WE EXPECT A SIGNAL ENHANCEMENT OF AT LEAST 60DB. THE KEY CONCEPT IS TO COAX THE PARTICLES TO SOFT CAVITATE AND DETECT THE ENSUING TR ...
