RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

A METHOD FOR INCREASING THE SENSITIVITY OF NUCLEIC ACID HYBRIDIZATION REACTIONS INVOLVING NON-RADIOACTIVE DNA PROBES IS EXAMINED. PACIFIC BIOTECHNOLOGY RESEARCH ASSOCIATES HAS A PROPRIETARY METHOD WHICH INCREASES THE HYBRIDIZATION EFFICIENCY OF RADIOACTIVELY-LABELED GENETIC PROBES BY OVER 1000%. THIS METHOD WILL BE APPLIED TO COMMERCIALLY-AVAILABLE SYSTEMS WHICH PRODUCE NON-RADIOACTIVE DNA PROBES ...

IMMOBILIZED FORMS OF ENZYMES HAVE OUTSTANDING PROMISE AS INDUSTRIAL CATALYSTS TO MAKE OR MODIFY PRODUCTS; AND ADVANCES IN IMMOBILIZED ENZYME TECHNOLOGY CAN HAVE A MAJOR ECONOMIC IMPACT ON THE PRODUCTION OF FOODS AND OTHER MATERIALS. ENZYME TECHNOLOGY RESEARCH GROUP, INC. IS DESIGNING THE DEVELOPING UNIQUE CARRAGEENAN-BASED SUPPORTS FOR IMMOBILIZED ENZYMES. THE OBJECTIVE OF THIS PROJECT IS TO DESIG ...

VIRTUALLY ALL POLYMERIC MEMBRANES ARE MORE PERMEABLE TO OXYGEN THAN TO NITROGEN. IN CURRENT COMMERCIAL MEMBRANES THE RATIO OF OXYGEN TO NITROGEN PERMEABILITIES IS BETWEEN 2 AND 5. WITH THESE LOW SELECTIVITIES, THE HIGHEST-PURITY OXYGEN-ENRICHED AIR OBTAINABLE IN A SINGLE MEMBRANE STAGE ISABOUT 50%-AND MORE TYPICALLY, MEMBRANE PROCESSES MAKE 30 TO 35% OXYGEN. THIS PROPOSAL ADDRESSES THE DEVELOPMENT ...

AN INSTRUMENT WILL BE DEVELOPED FOR THE IN SITU MEASUREMENT OF ABSORPTION OF 670 NM WAVELENGTH LIGHT BY MARINE PARTICLES. THE INSTRUMENT WILL MAKE USE OF A LARGE AREA DETECTOR AND A REFLECTING TUBE ALIGNED COAXIALLY WITH THE MAIN LIGHT BEAM. INITIAL RESEARCH WILL FOCUS ON THE OPTIMIZATION OF TECHNIQUE AND MATERIAL FOR THE DESIGN OF THEREFLECTING TUBE TO TRANSMIT ALL OF THE LIGHT SCATTERED FORWARD ...

THE PROGRAM PROPOSED HEREIN INVOLVES ANALYTICAL AND EXPERIMENTAL RESEARCH TO CAREFULLY EVALUATE AND FURTHER DEVELOP THE DIFFERENTIAL GAMMA SCATTERING TECHNIQUE FOR ACCURATE NON-INVASIVE DETERMINATION OF VOIDS, CRACKS, FLAWS IN MATERIALS AND THE DEFECTS SIZING AND LOCATION CAPABILITIES OF THIS METHOD. THIS NEW DEVICE, WHICH WE HAVE TERMED "DIFFERENTIAL GAMMA SCATTERING SPECTRUM PROBE (DGSSP)," IS B ...

THIS EFFORT WILL INVESTIGATE A THREE DIMENSIONAL VIDEO DISPLAY SYSTEM. THE SYSTEM WILL NOT REQUIRE VIEWING APPARATUS (SPECIAL GLASSES, ETC.) AND IS COMPATIBLE WITH EXISTING TV SYSTEMS. IT WILL USE A BASIC STEREOSCOPIC 3D TECHNIQUE DEVELOPED SEVERAL YEARS AGO, BUT THE NEW SYSTEM WILL INCORPORATE UNIQUE IMAGE PROCESSING THAT CORRECTS DEFECTS OTHERWISE INHERENT IN ALL SYSTEMS THAT DISPLAY STEREOSCOPI ...

THE PROPOSED WORK WOULD RESULT IN THE DEVELOPMENT OF A SUPERVISORY CONTROL SYSTEM FOR FLEXIBLE MANUFACTURING SYSTEMS (FMS) IN GENERAL, AND COOPERATING MULTI-ROBOT SYSTEMS IN PARTICULAR. THIS SYSTEM, TO BE REFERRED TO AS ANACTIVITY CONTROLLER (AC), WILL BE ORGANIZED IN A HIERARCHICAL STRUCTURE WHERE THE LEVELS OF THE HIERARCHY CORRESPOND TO THE DIFFERENT DECISION TYPES NECESSARY TO CONTROL A FMS. A ...
