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 ...

INDEPENDENTS IN THE MID-CONTINENT AREA INCLUDING OKLAHOMA AND KANSAS, NEED A NEW AND NOVEL WATER SOLUBLE POLYMER FOR INDEPTH MOBILITY CONTROL IN ENHANCED OIL RECOVERY (EOR) PROCESSES AT INTERMEDIATE TEMPERATURES OF 165 TO 200 FAHRENHEIT. PARTIALLY HYDROLYZED POLYACRYLAMIDES AND NATURAL POLYMERS HAVE HISTORICALLY BEEN THE PRODUCTS USED IN THIS REGION. AND IN ESSENTIALLY ALL OF THE EARLIER EOR PROJE ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...

MANY UTILITY AND INDUSTRY COAL-FIRED BOILERS HAVE ELECTROSTATIC PRECIPITATORS (ESPS) ALONE, WHICH ARE NOT CAPABLE OF REMOVING SO2. MANY OLDER ESPS WILL REQUIRE UPGRADING IN THE 1990S TO MEET MORE STRINGENT PARTICULATE STANDARDS. ETS, INC. HAS TESTED ITS PATENTED LIMESTONE EMISSION CONTROL (LEC) SYSTEM, DEMONSTRATING GREATER THAN 90% SO2 REMOVAL CAPABILITY. LECS CAN BE PLACED DOWNSTREAM OF ESPS. IT ...

THE PURPOSE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING AN INTELLIGENT CUSTOMER LOAD CONTROLLER IMPLEMENTED WITH AN EXPERT SYSTEM. CONVENTIONAL ELECTRICAL LOAD CONTROL DEVICES IMPLEMENT CONTROLLING FUNCTIONS BASED ON PREDETERMINED ALGORITHMS WHICH MAKE ASSUMPTIONS ABOUT TYPICAL USE PATTERNS. USE OF AN EXPERT SYSTEM WITH A LEARNING ALGORITHM IN A LOAD CONTROLLER WOULD PERMIT THE C ...

N/A

THE USE OF ADVANCED MATERIALS SUCH AS CERAMICS, CERAMIC COMPOSITES, AND HIGH TEMPERATURE COATINGS HAS LED TO IMPROVED PERFORMANCE OF CRITICAL HEAT ENGINE AND ENERGY-RELATED COMPONENTS AND SYSTEMS. HOWEVER, THE REQUIREMENTS FOR NONDESTRUCTIVE EVALUATION (NDE) OF CERAMIC MATERIALS RESULTING FROM COMPLEX GEOMETRY, INHOMOGENEITY, REDUCED FLAW SIZE, AND ADVERSE PROCESSING ENVIRONMENTS HAVE PRODUCED LON ...

THE CONCEPT FOR A BULK OPTICALLY-CONTROLLED SEMICONDUCTOR SWITCH (BOSS), WHERE TWO DIFFERENT WAVELENGTH LASERS ARE USED TO GENERATE AND QUENCH PHOTOCONDUCTIVITY WAS RECENTLY INTRODUCED BY SCHOENBACH AND LAKDAWALA AT OLD DOMINION UNIVERSITY (ODU). INSTEAD OF SUSTAINING PHOTOCONDUCTANCE BYLASER LIGHT, AS IN CONVENTIONAL PHOTOCONDUCTIVE SWITCHES, ONE LASER IS USED TO DRIVE THE SWITCH INTO A CONDUCTIV ...
