THIS RESEARCH IS DIRECTED TOWARD THE VOLUME VISUALIZATION ONA MASSIVELY PARALLEL COMPUTER (MPC) OF THE ANALYZED RESULTS IN PARALLEL WITH TIME-DEPENDENT ANALYSIS. IN THE PRESENT VOLUME VISUALIZATION TECHNIQUE, THE VOLUMETRIC DATA THAT MAYBE OBTAINED FROM NUMERICAL OR EXPERIMENTAL STUDIES ARE DIRECTLY RENDERED ONTO THE SCREEN. THE TECHNIQUE IS OBJECT ORIENTED AND IS BASED ON A CELL-BY-CELL VOXEL PRO ...

COALESCING THE FRAGMENTED INFORMATION ASSOCIATED WITH EACH EVENT OF A HIGH-ENERGY PHYSICS DETECTOR AND THEN PROCESSING IT AT THE RATES DEMANDED BY ACCELERATOR SYSTEMS ARE AMONG THE LARGEST CHALLENGES IN THE PHYSICS COMMUNITY. NEW DETECTOR SYSTEMS CONTINUE TO INCREASE THE NUMBER OF MEASURED PARAMETERS AND SIMULTANEOUSLY INCREASE THE RESOLUTION OF DETECTOR COMPONENTS SO THAT THE VOLUME OF GENRATED ...

ION SOURCES BASED ON VACUUM ARC TECHNOLOGY HAVE SEVERAL IMPORTANT ADVANTAGES. THEY CAN GENERATE A WIDE VARIETY OF METAL IONS, PRODUCE HIGH CURRENT FRACTIONS OF MULTIPLY-CHARGED IONS, AND ARE EASY TO OPERATE. UNFORTUNATELY, EXISTING ARC SOURCES HAVE TECHNOLOGICAL DRAWBACKS. A STABLE DISCHARGE REQUIRES HIGH CURRENT (>200A), LIMITING THE SOURCE PULSE LENGTH AND LIFETIME. IN THIS PHASE I PROJECT, IMPR ...

40837 November 13, 1996 TomoSeis, Inc. Crosswell Seismic Imaging holds great promise for imaging the region between existing oil wells to incrementally increase the recovery of the 368 billion barrels of oil still in the ground (of the 500 billion barrels of original oil in place in the U.S.). To make crosswell data acquisition cost effective, surveys mu ...

A NEW TECHNIQUE, PULSED ELECTRON BEAM (PEB) JOINING, WILL BE APPLIED TO THE PROBLEM OF JOINING, LOW-LOSS CERAMIC MATERIALS USED FOR WINDOWS IN HIGH FREQUENCY MICROWAVE DEVICES TO THE METAL VACUUM ENVELOPE OF THE MICROWAVE DEVICE. THE PEB TECHNIQUE ALLOWS SELECTIVE HEATING OF THE SPECIMEN TO BE JOINED THROUGH PREFERENTIAL ENERGY DEPOSITION THAT IS CONTROLLED BY A COMBINATION OF THE ELECTRON BEAM P ...

RELIABLE INTRUSION DETECTION MAY BE ACHIEVED BY COMBINING GENERALIZED POTENTIAL FUNCTION (GPF) NEURAL NET CONSTRUCTION AND MULTIPLE SENSOR DATA FUSION. TRADITIONALLY, RELIABLE INTRUSION DETECTION CAN BE DIFFICULT BECAUSE NOISE LEVELS CHANGE WITH TIME AND LOCATION, AND AN INTRUSION MAY PRODUCE A WIDE RANGE OF SIGNALS OR VARIATIONS OVER THE DIFFERENT TYPES OF SENSORS. ACCOMMODATING THESE VARIATION ...

GAS TRANSMISSION PIPELINES REQUIRE NATURAL GAS DELIVERED TO THEM TO MEET A HYDROCARBON (HC) DEWPOINT SPECIFICATION IN ORDER THAT THE HC LIQUIDS ARE NOT DROPPED OUT IN THE LINE DURING TRANSMISSION. SIMILAR SPECIFICATIONS ARE IMPOSED BY PLANT OPERATORS ON THE FUEL GAS THAT IS CONSUMED BY THEIR MACHINERY. A MARKET EXISTS FOR AN ECONOMICAL AMMONIA (NH3) ABSORPTION UNIT TO REPLACE COMPRESSION UNITS U ...
