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 ...

THE U.S. HAS AN ESTIMATED 327 BILLION BARRELS OF OIL IN EXISTING PRODUCTION FIELDS WHICH REMAINS IN PLACE EVEN AFTERPRIMARY AND SECONDARY RECOVERY TECHNIQUES HAVE BEEN EMPLOYED. HIGH RESOLUTION BOREHOLE-TO-BOREHOLE SEISMIC TOMOGRAPHY CAN PROVIDE THE INFORMATION NEEDED TO LOCATE THESE UNPRODUCED REGIONS THROUGH THE IDENTIFICATION OF SUBTLE GEOLOGIC ANOMALIES AND CAN BE USED TO ASSESS THE PROGRESS O ...

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 ...

IN MANY FLUID INJECTION PROCESSES USED FOR OIL RECOVERY, SUCH AS WATERFLOODING, THE INJECTED FLUIDS FLOW PREFERENTIALLY THROUGH THE ROCK ZONES OF HIGH FLOW CAPACITY (HIGH PERMEABILITY), BYPASSING OIL THAT IS PRESENT IN THE TIGHTER PARTS OF THE RESERVOIR ROCK. THIS MAY RESULT IN HIGH WATER-TO-OIL-PRODUCING RATIOS AND ABANDONMENT OF A PROJECT AT A RELATIVELY LOW VOLUMETRIC SWEEP EFFICIENCY. ONE APPR ...

A NOVEL CLASS OF TIME AND POSITION SENSITIVE (XYT) PARTICLE DETECTOR AND SUPPORTING ELECTRONICS IS PROPOSED WHICH CAN AFFORD A PRACTICAL MEANS OF COMBINING IMAGING AND TIME-OF-FLIGHT (TOF) ANALYSES IN A VARIETY OF ADVANCED INSTRUMENTS. DETECTOR SYSTEMS FOR PHOTONS, ELECTRONS AND IONS ARE TYPICALLY THE FIRST COMPONENTS IN MATERIALS CHARACTERIZATION INSTRUMENTS; FUNDAMENTAL IMPROVEMENTS HERE CAN HAV ...

THE OBJECTIVE OF OUR PROJECT IS TO DEVELOP NEW MEANS OF PRODUCING SHORT LIVED RADIOISOTOPES FOR POSITRON EMISSION TOMOGRAPHY (PET). THIS MEDICAL DIAGNOSTIC TECHNIQUE IS CAPABLE OF DISCERNING AND IMAGING MEDICALLY INTERESTING PHENOMENA, SUCH AS THE ACTIVITY OF VARIOUS PARTS OF THE BRAIN, OXYGEN FLOW IN THE BODY, AND OTHER QUANTITIES WHICH ARE IMPOSSIBLE TO DETERMINE BY ANY OTHER DIAGNOSTIC TECHNIQU ...

BLENDS OF BIOBASED FIBER SOURCES ARE MANUFACTURED AND CHARACTERIZED BY ASPECT RATIO FOR OPTIMUM PERFORMANCE IN A BIOBASED GRAFT POLYMER AS MEASURED BY MECHANICAL PROPERTIES AND SURFACE MORPHOLOGY IN COMPRESSION MOLDED TEST SPECIMENS. FROM 18 FORMULATIONS OF BIOBASED GRAFT POLYMER, THREE ARE SELECTED ON THE BASIS OF BEST OVERALL PERFORMANCE AND USED IN A BIOBASED GRAFT POLYMER COMPOSITE STUDY IN CO ...

A STRUCTURAL SUPPORT SYSTEM FOR LARGE APERTURE, STRETCHED MEMBRANE HELIOSTATS WILL BE DEVELOPED. THIS SUPPORT SYSTEM PROVIDES A TRACKING PLATFORM AND RESISTANCE TO THE WIND LOADENVIRONMENT. STRETCHED MEMBRANE HELIOSTATS ENJOY A SIMPLICITY AND STRUCTURAL EFFICIENCY THAT RESULTS IN LOW REFLECTOR COSTS. MEMBRANE TECHNOLOGY IS PARTICULARLY SUITEDTO CAPTURE ECONOMIES OF SCALE THROUGH LARGE APERTURE CON ...
