Abstract:Today's tactical aircraft employ sophisticated onboard sensors which can be managed in several dimensions, including spatial focus, sensing modality, and temporal scheduling. Effective mission operations, such as air interdiction and counter air, require efficient sensor control and scheduling that… more
Abstract:In Phase I, ALPHATECH will define a model-neutral data structure and supporting access mechanisms that will provide interoperability between different modeling methodologies in support of large scale systems engineering. The model-neutral data structure will provide a common data representation of… more
Abstract:There are strong motivations for the development of accurate, efficient algorithms for the three-dimensional location of stationary or moving targets from one or more video sensors. In this proposal we describe an effort to accomplish this task by exploiting ALPHATECH's unique expertise in all… more
Abstract:The objective of this research is to define and validate an Avionics Information Fusion System (AIFS) which optimally combines onboard and offboard data. We propose an architecture containing an offboard data processor to extract data relevant to the mission, and a set of fusion modules for… more
Abstract:Low power has been recently elevated to one of the most critical issues in circuit design, affecting circuit reliability, battery life, and heat sinking. In spite of this demand, surprisingly little support from CAD vendors exists for automated low power circuit design. Alternative System Concepts… more
Abstract:Combustion in boiler and fluids heaters consumes approximately 5 TCF of gas peryear and generates approximately 350,000 tons of NOx. To meet ambient airquality standards, particularly those for ozone, low-cost ultra-low NOx burnersare needed for these applica-tions. This will reduce the costs and… more
Abstract:Enzyme microcrystals (less than 100 um) grown from aqueous solution and cross-linked witha bifunctional agent such as glutaraldehyde exhibit remarkable characteristics that are superior to bothsoluble and conventionally immobilized enzymes. Such cross-linked enzyme crystals (CLECs) remainactive in… more
Abstract:Amain Electronics has developed an innovative on focal plane digital readout approach which not only provides the necessary pixel size and linear dynamic range for multicolor detector interfacing, but also generates an offset free output data stream that can be input directly into a digital image… more
Abstract:A free space optical data link is proposed based upon the use of symmetric self electro-optic effect device, the S-SEED. This device, a multiple quantum well based p-i-n diode pair, is a photonic switch which can be utilized as an electrically modulated reflector or inversely as an optically… more
Abstract:The ability to fully exploit the low level light vision advantages for surveillance systems offered by advanced two-dimensional infrared detector arrays is compromised by the cost, weight and size of existing analog sampling and multiplexing technologies. Amain Electronics proposes an innovative on… more
Abstract:The engineering of materials on a nanometer scale is an important technological goal which would facilitate the development of a new generation of materials and devices. A variety of biological membranes exhibit self-assembly into 2-D arrays including the purple membrane from Halobacteria… more
Abstract:Nonisotopic calorimetric and chemiluminescent technologies will be developed for use withribonuclease protection assays. The ribonuclease protection assay is an increasingly utilized techniquein molecular biology affording sensitive and quantitative measurement of mRNA levels. The ability ofthe… more
Abstract:This effort will integrate an advanced technology speech recognition system (SRS) with a computer-assisted contingency planning training model. The SRS makes use of algorithms developed in the Speech Technology and Research Labratory of SRI International. Its state-of-the-art approach provides… more
Abstract:This Phase I proposal is intended to develop an advanced Battlefield Management and Expert Cueing (BFMEC) System using distributed expert system decision aids for direct/indirect fire. The BFMEC is aimed at small units (such as an artillery battery) and will incorporate recent technological… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
