INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCAITED METHODOLOGY FOR PERFORMING RAPID AND ACCURAGE MEASUREMENTS OF RANGE/LOCATION OF THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITY WITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/PROCESSING EQUIPME ...

REALIZATION OF THE PERFORMANCE ADVANTAGES OF SUPERCONDUCTING DEVICES IN HIGH FREQUENCY COMMUNICATIONS DEPENDS ON DEVELOPMENT OF A LOW TEMPERATURE DEPOSITION PROCESS WITH EXACTING CONTROL OF STOICHIOMETRY AND MORPHOLOGY. MOCVD CAN MEET THESE NEEDS COUPLED WITH EASE OFSCALE-UP. HOWEVER, RECENT WORK AT ADVANCED TECHNOLOGY MATERIALS, INC. SHOWS THAT YBACUO AND BISRCACUO FILMS GROWN BY MOCVD AT TEMPERA ...

THERE HAS BEEN RECENT INTEREST IN THE SMALL SCALE PRODUCTIONOF LIQUIDS FROM COAL BY MILD GASIFICATION WHICH CAN BE INTEGRATED INTO THE CURRENT ENERGY INFRASTRUCTURE. WHILE MOST WORK ON MILD GASIFICATION IS ADDRESSING DENSE PHASE REACTORS OR LARGE PARTICLES, SEVERAL LABORATORIES REPORT THAT FLASH PYROLYSIS USING SMALL PARTICLES IN DISPERSED-PHASE REACTORS PRODUCES A HIGHER YIELD (SOMETIMES TWO TO T ...

FOR SURFACES AT HIGH TEMPERATURE, THE EMITTED SPECTRUM OF ELECTRO-MAGNETIC RADIATION IS THE MOST CONVENIENT PROBE OF TEMPERATURE, IF THE SPECTRAL EMITTANCE OF THE SAMPLE IS KNOWN. THIS PROPOSAL SUGGESTS THE APPLICATION OF A NOVEL, NON-INTRUSIVE SURFACE TEMPERATURE MEASUREMENT TECHNIQUE FOR THE IN-SITU DETERMINATION OF BOTH TEMPERATURE AND EMISSIVITY. THE TECHNIQUE EMPLOYS SMALL LOCAL MODULATION OF ...

THE U.S. EPA ESTIMATES THAT 290 MILLION TONS OF HAZARDOUS WASTE ARE PRODUCED ANNUALLY IN THE U.S. THE MOST PROMISING METHOD FOR THE PERMANENT DISPOSAL OF ORGANIC WASTES IS HIGH-TEMPERATURE INCINERATION. WHILE SOLAR INCINERATION OFFERS SIGNIFICANT PROMISE AS A WASTE DISPOSAL TECHNOLOGY, THERE IS A STRONG NEED FOR ON-LINE AND IN-SITU DIAGNOSTICS DURING THE DEVELOPMENT OF THE PROCESS AND FOR EVENTUAL ...

A NOVEL BIOELECTRODE WILL BE FABRICATED FROM CONDUCTING POLYMERS. UNDER PROPER CONDITIONS, THIS BIOELECTRODE CAN BEELECTROCHEMICALLY REDUCED WITH RESULTING INCORPORATION OF NEUROTRANSMITTERS, SUCH AS ACETYLCHOLINE, -AMINOBUTYRATE, DOPAMINE, OR GLUTAMATE, INTO THE POLYMER MATRIX OF THE BIOELECTRODE. THE NEUROTRANSMITTER CAN REMAIN ENTRAPPED WITHIN THE CONDUCTING POLYMER MATRIX WHEN THE BIOELECTRODE ...

OVER THE PAST FIFTEEN YEARS NUMEROUS IMPLANTABLE BIOSENSORS HAVE BEEN DEVELOPED, BUT THEIR COMMERCIAL VIABILITY IS LIMITED MOSTLY BECAUSE OF FAILURE DUE TO TISSUE OR BODY FLUID CORROSION OVER EXTENDED PERIODS. THE CHALLENGE REMAINS TO DEVELOP A COATING MATERIAL WHICH WILL ADHERE TO THE BIOSENSOR, NOT DEGRADE IN THE PRESENCE OF AN ELECTRIC FIELD, BE THIN ENOUGH TO ALLOW FOR USE WITH MICROELECTRONIC ...

THERE IS A NEED FOR IMPROVING THE FORECASTING OF LOCAL WEATHER ELEMENTS SUCH AS PRECIPITATION, SURFACE TEMPERATURE,ETC. CURRENT FORECASTS ARE MADE BY A STATISTICAL ADAPTATIONOF LARGE SCALE NUMERICAL FORECASTS. WE PROPOSE TO USE, INSTEAD, A MODEL THAT COMPUTES THE PHYSICAL PROCESSES THAT LOCALLY MODULATE THE LARGE SCALE METEOROLOGICAL FIELDS. THEPARAMETERS OF SUCH A MODEL NEED TO BE ADJUSTED TO THE ...

ONE OF THE MOST IMPORTANT CONTRIBUTIONS TO THE RADIATION EXPOSURE OF PERSONNEL ENGAGED IN SPACE FLIGHT IS THE SIGNIFICANT FLUX OF HIGH ENERGY NEUTRONS ARISING FROM BOTH PRIMARY AND SECONDARY SOURCES OF IONIZING RADIATION. PRESENTLY, THERE DOES NOT EXIST A SUITABLE AND COMPACT NEUTRON SENSOR CAPABLE OF BEING INCORPORATED IN A FLIGHT INSTRUMENT TO PROVIDE HIGH QUALITY, REAL TIME MEASUREMENT OF THIS ...

THE DISCOVERY OF SUPERCONDUCTIVITY AT HIGH TEMPERATURES (90 K) IN COPPER CONTAINING CERAMICS HAS RESULTED IN THE RAPID ACCELERATION OF SUPERCONDUCTOR RESEARCH. MUCH OF THISRESEARCH IS BEING DIRECTED AT PRODUCING AND EXAMINING NEW COMPOUNDS BOTH TO IMPROVE PERFORMANCE CHARACTERISTICS AND TOBETTER UNDERSTAND THE PHENOMENON. REALIZING THE POTENTIAL COMMERCIAL BENEFITS OF THIS NEW DISCOVERY DEPENDS AS ...
