OPTICAL SYSTOLIC ARRAY PROCESSORS WERE INVENTED BY THE PRINCIPAL INVESTIGATOR TWO YEARS AGO AND HAVE BECOME THE SUBJECT OF INTENSE INTEREST IN THE UNITED STATES, THE SOVIET UNION, AND JAPAN. THEY OFFER THE SPEED OF SUPERCOMPUTERS (TENS OF GIGAFLOPS PER MODULE) WITH MUCH LOWER COST, VOLUME, AND POWER CONSUMPTION. WHAT NO ONE IS STUDYING IS HOW TO OPERATE THESE MODULES IN PARALLEL TO SOLVE LARGE LIN ...

IN THIS STUDY, WE PROPOSE TO INVESTIGATE A NEW TYPE OF PLASMA ION SOURCE IN WHICH IONS ARE PRODUCED BY THE LASER PHOTODISSOCIATION OF A THALLIUM HALIDE VAPOR, SUCH AS OR . USING AN EXCIMER LASER AS A LIGHT SOURCE, IT SHOULD BE POSSIBLE TO PRODUCE APPROXIMATELY 10(18) CM(-3) , AND OR ION PAIRS PER LASER PULSE. TEN TO 100 SUCH PULSES COULD BE PRODUCED PER SECOND. THIS SOURCE IS POTENTIALLY FIVE ORDE ...

POSITRON EMISSION TOMOGRAPHY IS A NONINVASIVE NUCLEAR IMAGING TECHNIQUE WHICH IS BECOMING AN IMPORTANT FUNDAMENTAL TOOL FOR BOTH CLINICAL DIAGNOSIS AND MEDICAL RESEARCH. THE HEART OF THIS INSTRUMENT IS A LARGE ARRAY OF SCINTILLATOR-PHOTOMULTIPLIER TUBE DETECTORS. THE AVAILABILITY OF A COMPACT SOLID STATE SENSOR TO REPLACE THE VACUUM TUBE DETECTORS IN THIS ARRAY WOULD SIGNIFICANTLY REDUCE THE SIZE ...

THE PRODUCTION OF HYBRIDOMAS BY CELL FUSION IS AN INCREASINGLY IMPORTANT ASPECT OF BOTH MEDICAL RESEARCH AND CLINICAL PROTOCOLS. IN PARTICULAR, IT HAS THE POTENTIAL FOR PROVIDING SENSITIVE DIAGNOSTIC REAGENTS TO RADIATION INDUCED CELL DAMAGE. WE HAVE RECENTLY CONDUCTED PRELIMINARY RESEARCH ON A NEW APPROACH, THE ELECTRONIC CELL FUSION TECHNIQUE. THIS TECHNIQUE USES AN ELECTRONIC IMPULSE TO PUNCTUR ...

NICKEL AND COBALT ARE STRATEGIC METALS THAT PLAY A VITAL ROLE IN UNITED STATES INDUSTRY AND DEFENSE. CURRENT PRODUCTION COMES LARGELY FROM A DWINDLING SUPPLY OF NON-DOMESTIC SULFIDE ORE DEPOSITS. OXIDE ORES SUCH AS LATERITES AND, IN THE FUTURE, MANGANESE OCEAN NODULES ARE MORE PLENTIFUL AND WILL BECOME INCREASINGLY IMPORTANT RESOURCES. EXTRACTIVE AND SEPARATION TECHNOLOGIES THUS FAR DEVELOPED FOR ...

THE PROGRAM WILL EXPLORE THE FEASIBILITY OF GROWING SILICON SHEET CRYSTALS HORIZONTALLY USING THE EDGE-SUPPORTED PULLING(ESP) PROCESS FROM SILICON MELTS CONTAINED IN AN RF HEATED CRUCIBLE. THEORETICAL EVALUATION OF THE BASIC HORIZONTAL RIBBON GROWTH (HRG) PROCESS HAVE SHOWN QUITE CONCLUSIVELY THE ENORMOUS POTENTIAL OF THIS CRYSTAL GROWTH METHOD; I.E., IT SHOULD BE POSSIBLE TO PRODUCE LARGE, FLAT S ...

THE PRODUCTION OF COMMERCIALLY IMPORTANT CHEMICAL FEEDSTOCKSBY MICROBIAL FERMENTATION IS HINDERED BY THE INABILITY TO MONITOR THE ONSET OF PRODUCT AND/OR BYPRODUCT FORMATION. SINCE MANY MICROORGANISMS UTILIZING GLUCOSE AS A SUBSTRATE GENERATE CARBOXYLIC ACIDS, AN "IN SITU" ORGANIC ACID SENSOR WOULD BE A VALUABLE ADDITION TO ANY BIOREACTOR DESIGN. THROUGH THE USE OF A MULTIPHASE POTENTIODYNAMIC WAV ...
