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 ...

RESEARCH ON AN ALTERNATE MATERIAL, ANHYDRITE CALCIUM SULFATE, FOR USE AS CULTCH IN CONSTRUCTING SEED BEDS AND ARTIFICIAL OYSTER REEFS IS HEREIN PROPOSED. GIVEN THE FACTS THAT OYSTER PRODUCTION IN THE UNITED STATES HAS DECLINED GREATLY SINCE 1908 AND THAT NATURAL OYSTERSHELL IS SCARCE AND EXPENSIVE, MOTIVATION FOR USE OF THIS ALTERNATE MATERIAL AS CULTCH INCLUDES ITS CONTINUOUS PRODUCTION, LOW COST ...

DESIGN, SIMULATION, FABRICATION, AND EVALUATION OF A PROTOTYPE VERY LARGE SCALE INTEGRATION (VLSI) DATA ACQUISITION SUBSYSTEM IS PROPOSED. AVAILABLE STATE-OF-THE-ART ONE MICRON CMOS TECHNOLOGY MAY ALLOW INCORPORATION OF MORE THAN 128 CHANNELS OF 24-BIT 300 MHZ COUNTERS INTO A SINGLE INTEGRATED CIRCUIT. A PROTOTYPE SYSTEM OF SIMPLE REPEATED CELLS OF COUNTERS, CONTROL AND I/O BUFFERS HAS BEEN DESIGN ...

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 ...

TWO MAJOR OBSTACLES CONFRONTED PREVIOUS ATTEMPTS TO ANALYZE FIELD ICE BEHAVIOR; NAMELY: THE LACK OF PROPER CONSTITUTIVE LAWS TO MODEL REALISTIC ICE BEHAVIOR, PARTICULARLY AT HIGH STRAIN-RATES, AND THE DIFFICULTY IN INCORPORATING LARGE ICE DEFORMATIONS IN THE ANALYSIS. THIS PROPOSAL PRESENTS A STUDY WHICH WILL IMPLEMENT AN ICE CONSTITUTIVE MODEL SUBROUTINE TO WORK IN CONJUNCTION WITH A LAGRANGE EXP ...

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 ...

THIS IMPROVED DOWNHOLE DRILLING TOOL CONTROL SYSTEM PROVIDES A SIMPLER, LESS EXPENSIVE, AND MORE RELIABLE MEANS OF OPERATING MANY TYPES OF DRILLING, TEST, AND COMPLETION TOOLS. THE SYSTEM IS OPERATED BY TEMPORARY INCREASES IN PUMP PRESSURE, WITH AUTOMATIC COMPENSATION FOR CHANGES IN HYDROSTATIC PRESSURE. THE SYSTEM PROVIDES FEEDBACK, IS OF FULL-BORE DESIGN, IS COMPATIBLE WITH OTHER TYPES OF TOOLS, ...

IT IS PROPOSED THAT A NEW TYPE OF SOFT MAGNETIC MATERIAL CAN BE USED FOR A VERY SENSITIVE AND LOW MAGNETIC FIELD DETECTION DEVICE. TO DETECT THE MILITARY TARGETS, ONE NEEDS A HIGHLY SENSITIVE DEVICE BUT THE EXISTING FLUX-GATE MAGNETOMETERS ARE LIMITED BY THEIR SIGNAL-TONOISE RATIO. WITH THE DEVELOPMENT OF SUPERIOR MAGNETIC MATERIALS AND IMPROVED ELECTRONICS, SOME OF THE NOISE PROBLEMS IN FLUX-GATE ...

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 ...
