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 ...

AN EXISTING SYSTEM HAS DEMONSTRATED, IN QUIET CONDITIONS, VERY RELIABLE DETECTION OF HUMANS HIDDEN IN VEHICLES. SEISMIC VIBRATIONS ARE THE MAJOR, UNAVOIDABLE LIMITATIONS. MEASUREMENT OF THE SEISMIC VIBRATIONS AND COHERENT ANALYSES WILL BE UTILIZED TO COMPUTE AND SUBTRACT THE EFFECT OF THE SEISMIC INTERFERENCE ON THE VEHICLE MOTION. THE PHASE I EFFORT WILL IMPROVE THE RELIABILITY, INCREASE THE S ...

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 ...

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 ...

N/A

THIS PROJECT IS AIMED AT THE DEVELOPMENT OF A NEW GENERATION OF ROTARY BLOWOUT PREVENTERS CAPABLE OF SAFE, RELIABLE, AND COST EFFECTIVE HANDLING OF THE HIGH PRESSURES EXPECTED IN UNDERBALANCED HORIZONTAL AND DIRECTIONAL DRILLING APPLICATIONS. PRESSURES OF UP TO 5,000 PSI (OR EVEN HIGHER) CAN BE EXPECTED WHEN DRILLING WITH AIR, FOAM, OR NITRIFIED MUD IN THE LOW PERMEABILITY FORMATIONS IN THE U.S. ...

A NEAR LINEAR ACCELERATOR (LINAC) STRUCTURE WILL BE IDENTIFIED AND INVESTIGATED IN PHASE I AS A POSSIBLE EXTENSION TO THE FAMILY OF STRUCTURES NOW USED FOR ACCELERATION OF CHARGED PARTICLE BEAMS. A CANDIDATE STRUCTURE HAS BEEN IDENTIFIED; OTHERS MAY BE IDENTIFIED IN THE COURSE OF THE INVESTIGATION. THE IDENTIFIED STRUCTURE UTILIZES A FOUR-FINGERED GEOMETRY TO PRODUCE RADIO FREQUENCY (RF) ELECTRI ...

N/A

THE NATION DESIRES TO EXPAND THE USE OF CLEAN BURNING, COMPETITIVELY PRICED NATURAL GAS. THE INCREASED DEMAND FOR NATURAL GAS HAS PROMPTED NEW DRILLING IN ESTABLISHED GAS FIELDS. THE PROPER PLACEMENT OF THE NEW WELLS IS DEPENDENT ON THE GAS FORMATION PROPERTIES BETWEEN THE EXISTING WELLS. ONE OF THE PROPERTIES IS THE THICKNESS OF THE GAS BEARING ZONE. IT IS GENERALLY ACCEPTED THAT THE FORMATIO ...
