143 "Development of Energy Recovery, RF Power Rectifiers for Intense Particle Beam Applications"--Linac Systems, 2167 North Highway 77, Waxahachie, TX 75165-6215; (972) 937-3283 Dr. Donald A. Swenson, Principal Investigator Mrs. Barbara C. Swenson, Business Official DOE Grant No. DE-FG03-97ER82415 Amount: $74,980 Intense particle beam facilities, such as free-electron lasers, suggest the ne ...

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 ...

29 Enzyme Facilitated Transport Membranes--Sapient Catalytechs, Inc., P.O. Box 580284, , Houston, TX 77258-0284; (281) 333-5093 Dr. Russell L. Smith, Principal Investigator Dr. Michael C. Trachtenberg, Business Official DOE Grant No. DE-FG03-97ER82472 Amount: $74,990 There is a great need for improvements in efficient methods to reduce the cost of removing carbon dioxide from flue gas and nat ...

THIS PROJECT INVOLVES THE ANALYSIS OF A HIGH HARMONIC, HIGH EFFICIENCY MICROWAVE GENERATOR THAT APPEARS TO BE SUITABLE FOR APPLICATIONS SUCH AS A DRIVER FOR THE NEXT GENERATION OF LINEAR COLLIDERS. THE CONCEPT EMPLOYS A ROTATING "SPIRALING" BEAM TO EXCITE AND AMPLIFY CIRCULARLY POLARIZED MICROWARE RADIATION IN AN INTERACTION OUTPUT WAVEGUIDE. MODULATION OF A LINEAR, HIGH POWER, SMALL DIAMETER BEAM ...

40690 TPL, Inc. This project will develop a novel solid polymer electrolyte (SPE) that will significantly increase the practical power and energy density of state-of-the-art secondary lithium batteries. The approach will yield carbosilane-based electrolytes with high conductivities and low transference numbers. Covalently attaching thin films of these novel electrolytes to high energy density c ...

16 Fiber Optic for the Detection of Co-Contaminant Compounds--F&S, Inc., P.O. Box 11704, Blacksburg, VA 24062-1704; (540) 953-4274 Mr. Mark E. Jones, Principal Investigator Ms. Garnett S. Linkous, Business Official DOE Grant No. DE-FG02-97ER82371 Amount: $74,994 Innovative technologies to advance the measurement of biological and physicochemical properties of natural systems are necessary in ...

106 Crosswell Seismic in Three Dimensions--TomoSeis, Inc., 1650 West Sam Houston Parkway North, , Houston, TX 77043-3115; (713) 461-7360 Dr. Spyros Lazaratos, Principal Investigator Mr. Bruce P. Marion, Business Official DOE Grant No. DE-FG03-97ER82502 Amount: $74,997 Improved recovery of oil and gas from mature domestic fields depends on the detailed characterization of reservoir st ...

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 ...
