A MODULAR INPUT/OUTPUT SUBSYSTEM IS PROPOSED TO PROVIDE INTERFACE BETWEEN EXPERIMENTAL DATA ACQUISITION SYSTEMS USING THE CAMAC OR FASTBUS STANDARDS AND NEW-GENERATION DIGITAL EQUIPMENT CORPORATION MINICOMPUTERS. THE SYSTEM OFFERS A POTENTIAL TENFOLD INCREASE IN THE SPEED OF DATA ACQUISITION OVER CURRENT SYSTEMS. IT INCLUDES SUFFICIENT COMPUTER INTELLIGENCE TO MANAGE DATA TRANSFERS BETWEEN THE EXP ...

THE DIGITAL SIGNAL PROCESSING (DSP) INDUSTRY SUPPLIES ESSENTIAL TOOLS AND TECHNOLOGY TO A HOST OF DEFENSE AND CIVILIAN END-USERS. DSP PRODUCTS ARE FOUND IN MANY FIELDS INCLUDING COMMUNICATIONS, AUDIO, VIDEO, AUTOMATION, GEOPHYSICAL, MEDICAL, AND RADAR/SONAR APPLICATIONS. HOWEVER, MANY CRITICALLY IMPORTANT PROBLEMS CANNOT BE SERVEDBY THIS INDUSTRY DUE TO CURRENT COMPUTATIONAL LIMITATIONS OFDSP HARD ...

SEVERAL SPECIES OF THE SALVIA FAMILY, WHICH PRODUCE EDIBLE SEED PRODUCTS, WILL BE TEST GROWN AT AN EXPERIMENTAL FARM IN PHOENIX, ARIZONA. THE MOST PRODUCTIVE VARIETIES THAT ARE ADAPTABLE TO DESERT CLIMATE, AND THAT ARE ECONOMICAL WITH WATER, WILL BE SELECTED FOR INCREASE AND FURTHER TESTING. THE PRODUCTS OF THE SEEDS, (1) POLYSACCHARIDE GUMS, (2) PROTEINS, AND (3) OILS, WILL BE ANALYZED BY MODERN ...

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 ...

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 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 ...

A PROPOSED METHOD FOR GENERATING AN IMAGE IN DEPTH OF A GEOLOGIC CROSS-SECTION FROM OFFSET VERTICAL SEISMIC PROFILE (VSP) DATA WILL BE TESTED AND EVALUATED. THE PROPOSED METHOD USES WAVE EQUATION MIGRATION TECHNOLOGY COUPLED WITH A NEW IMAGING METHOD TO GENERATE THE IMAGE. THIS ELIMINATESTHE NEED FOR RAY TRACING AND ALLOWS FOR MORE COMPLEX VELOCITY MODELS THAN DO PRESENT METHODS. THE METHOD WILL B ...

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, ...

IMPROVED PREDICTIONS OF PETROLEUM RESERVOIR PERFORMANCE ARE NEEDED TO REDUCE THE RISKS ASSOCIATED WITH FIELD SCALE MISCIBLE FLOODING. A MAJOR SHORTCOMING OF CURRENT PREDICTION TECHNIQUES IS THE FAILURE TO ACCURATELY MODEL THE EFFECTS OF MOBILITY RATIO AND VISCOUS FINGERING ON VOLUMETRIC SWEEP AND DISPLACEMENT EFFICIENCY. THE PROPOSED RESEARCH WILL DEVELOP IMPROVED NUMERICAL TECHNIQUES FOR THIS PRO ...
