THIS RESEARCH PROJECT WILL DIRECTLY ADDRESS THE PROBLEM OF SWEEP IMPROVEMENT FOR ENHANCED OIL RECOVERY (EOR) PROCESSES. ONE OF THE MAJOR PROBLEMS IN CONDUCTING AN EFFICIENT EOR PROCESS IS THE CONTROL OF THE INJECTED FLUIDS. IN MOST FIELD APPLICATIONS OF MISCIBLE OR IMMISCIBLE SOLVENT DRIVES, SUCH AS CARBON DIOXIDE OR LIGHT HYDROCARBON FLOODS, THE PRESENCE OF RESERVOIR HETEROGENEITIES LEADS TO EARL ...

A MOLTEN SALT PROCESS IS DESCRIBED FOR SEPARATING THE COMPONENTS OF THE ALLOY OF ENRICHED URANIUM AND IRON WHICH IS THE PRODUCT OF THE ATOMIC VAPOR LASER ISOTOPE SEPARATION (AVLIS) PROCESS TO ENRICH THE (235)U CONTENT OF THE PRENT METAL. A SIMPLE SEPARATION WOULD DISSOLVE THE ENRICHED URANIUM HEXAFLUORIDE WHICH WOULD BE RECOVERED AND PURIFIED BY VAPORIZATION FROM THE MOLTEN SALT. VAPORIZED AND CON ...

THIS PROJECT WILL DEVELOP A FREQUENCY STANDARD FOR THE URANIUM-STOMIC VAPOR LASER ISOTOPE SEPARATION (U-AVLIS) PROCESS USING A VISIBLE DIODE LASER LOCKED TO AN ATOMIC RESONANCE. A KEY FEATURE IS THE USE OF THE VELOCITY MODULATION METHOD TO PROVIDE A HIGH SIGNAL/NOISE LOCKING DISCRIMINANT WITHOUT THE NEED TO MODULATE THE LASER, AND WITH THE HIGH POWERS FOR SUB-DOPPLER EFFECTS. PHASE I WILL PRODUCE ...

PHASE I ADDRESSES A NEW APPROACH FOR THE DESIGN OF HIGH POWER NUCLEAR TARGETS USED FOR PRODUCTION OF RADIOISOTOPES BY HIGH ENERGY CHARGED PARTICLE BEAMS, NOTABLY HIGH ENERGY PROTONS. SUCH TARGETS WILL YIELD LARGER QUANTITIES OF RADIOACTIVE SPECIES THAN PRESENTLY AVAILABLE, EITHER FOR BASIC RESEARCH (E.G., STUDIES USING RADIOACTIVE BEAMS) OR FOR APPLIED PURPOSES (E.G., PRODUCTION OF MEDICAL RADIOI ...

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 ...
