Southwest Sciences will develop a novel fire detection technology based on optical spectroscopy, using diode lasers and fiber optics. Rapid, quantitative detection of part per million concentrations (or better) of multiple gases, including carbon monoxide, carbon dioxide, hydrogen cyanide, hydrogen chloride, and a fiber optical distribution network permits one laser to be used for at least 800 di ...

The principal factor preventing wide use of the Josephson primary voltage standard is its cost. By reducing the cost of a HYPRES voltage standard to a level comparable with true cost of secondary standards (including the cost of calibration and low accuracy, etc.), and making it easy to use, we intend to put the Josephson voltage Standard within reach of most secondary standard users. In phase I ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

Converted from advanced automatic target recognition (ATR) processors, this new feature extraction/GIS system (a) uses raster data as input, and thus eliminates manual digitization; (b) uses expert systems to extract features automatically, and thus eliminates time-consuming and error-prone manual object tracing; and (c) vectorizes the extracted objects and converts them into GIS layers automatica ...

The purpose of the VMIS is to allow manufacturers the luxury of testing and perfecting manufacturing plans long before a single machine tool is turned on and resources are committed. The VMIS will allow the user to select an available machine tool and an available inspection device, specify a proposed inspection plan and a dimensional analysis procedure, and then build and inspect hundreds (or ev ...

The project will research a new generation of optic for focusing cold neutrons using tapered capillary optics. The success of the program will result in neutron beam probes with unprecedented spatial resolution and detection limits for small sample volumes. The individuals involved are the world leaders in neutron focusing capillary optics, having achieved better than an order-of-magnitude impro ...

RECENT DEVELOPMENTS EMPLOYING OBJECT-ORIENTED DATA MODELS HAVE DEMONSTRATED THE FEASIBILITY OF REPRESENTING COMPLEX AND ABSTRACT CARTOGRAPHIC FEATURES AS COMPOSITES OF SIMPLER FEATURES. SEPARATE DEVELOPMENTS IN NEURAL-NETWORK TECHNOLOGY HAVE SHOWN PROMISE IN RECOGNIZING OR EXTRACTING SPATIAL FEATURES WITHIN SAMPLE DATA SETS. COMBINING OBJECT-ORIENTED AND NEURAL-NETWORKS APPROACHES MAY LEAD TO NEW ...

Current battlefield situation displays either lack resolution ir restrict the user's perception to a small segment of the battlefield. Additionally, the plotting of data on these displays is extremely manpower-intensive, consuming valuable personnel resources that could be applied to situation analysis and other important tasks. Trident proposes to design and produce an innovative situation awar ...

The world wide communications infrastructure is undergoing dramatic revision, with optic fiber providing virtually limitless bandwidth, and wireless communication connecting increasingly mobile users to that fiber backbone. However, cost-effective evolution to an information-rich society will require strong standardization of wireless communication technology. The United States gave birth to the ...

Not Available It is proposed to develop an advanced field apparatus for measuring the thermal conductivity of ceramic powders over the range of temperatures from room temperature to 1500 to 2500 K, depending upon the particular material and its compatibility with other materials. The apparatus will have the capability to carry out fully automated thermal conductivity measurements, by transient or ...
