Explosions and high-velocity impacts can create strain rates on the order of 105 to 107 s-1. To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test procedure is neede ...

Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

IT IS PROPOSED THAT "LIMITED SENSING" ASYNCHRONOUS RANDOM-ACCESS TRANSMISSION ALGORITHMS BE DEVELOPED, ANALYZED, AND EVALUATED, FOR DATA LOCAL AREA NETWORKS, (LAN'S). THE LAN TOPOLOGIES CONSIDERED ARE MAINLY MOBILE RADIO AND ETHERNET-TYPE CONFIGURATIONS. THE ASYNCHRONOUS, LIMITED SENSING CLASS OF RANDOM-ACCESS ALGORITHMS IS MOST APPROPRIATE FOR SUCH TOPOLOGIES, ATTAINING SUPERIOR PERFORMANCE CHARA ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...
