Abstract:The small spacecraft power system proposed in this program provides significant advantages over state-of-the-art systems including: (1) use of a high efficiency (25%-35%) AMTEC, static power conversion system, (2) reduced planform area, and vulnerability, (3) mass efficient phase change material for… more
Abstract:A great need exists for a high brightness laser which is consistent, easy-to-use, and reliable for use in industrial, scientific, and military applications. A new enhanced photolytic iodine laser is proposed which is unique in it's simultaneously available attributes. Phase I will assess scalability… more
Abstract:Spatial light modulators are the limited component of optical signal processors. Electronic modulators, including liquid crystals and magento-optic modulators, are expensive, low resolution, and slow. The optical disk offers high resolution at moderate cost. The "pixel" size is on the order of one… more
Abstract:We propose a system to determine object attitude from special video imagery taken from two locations, with an image analysis system based on the Fourier Transform, which provides the spatial power spectrum of the image. The Fourier transform of an image represents the information in terms of angles… more
Abstract:Advanced Photonics Technology (APT) proposes to develop novel, wide-band, highly linear integrated-optical modulators based on low-loss waveguides in ferroelectric (e.g., lithium niobate and lithium tantalate) crystals with domain-inverted sections. The application of domain inversion to… more
Abstract:It is difficult to remove oil and AFFF from voluminous streams. Research has been continously carried out to develop new technologies to be employed in this field of application with little success. Air-sparged hydrocyclone (ASH) flotation technology is a new technology developed by the University… more
Abstract:The use of commercially available technology for military hardware either as it exists off-the-shelf or with slight modification presents a large opportunity for cost saving in both the non-recurring development cost and the recurring cost of production and maintenance of military hardware. This… more
Abstract:The Second Generation Helicopter Analysis System (2GCHAS) has been developed to provide a common framework for interdisciplinary design and analysis of rotorcraft systems. A current limitation is the level of sophistication available in modeling advanced control systems. Advanced Rotorcraft… more
Abstract:With the growing acceptance of the new ADS-33C handling qualities specification, it is essential that flight test engineers and pilots be effectively trained in this new methodology as soon as possible. personal Computer (PC) based tutorials provide convenient and cost effective training aids,… more
Abstract:We propose to develo a numerically efficient rotorcraft trim and transient response algorithm. The algorithm is intended for application in a periodic dynamic system with a large number of degrees of freedom as is commonly the case in current comprehensive rotorcraft analysis codes (such as 2GCHAS)… more
Abstract:We Propose to enhance rotorcraft simulation model to support land and sea-based flight testing and operational analysis. The model enhancement will resolve the long-time perplexing problems related to the fundamental simulation requirement for an accurate prediction of rotorcraft response in… more

Advanced Safeguards, Inc.
In high-security Department of Energy and Department of Defense facilities, cold-chemical smoke generators are used to produce visual obscurants in order to delay unauthorized intruders. The technology is… more
Abstract:A novel solid state detector has been designed to detect radioactive isotopes in gas. It will detect tritium in the atmosphere in concentrations as low as 0.1 microCuries per cubic meter (1 picoCurie for cubic centimeter) in au intense background environment containing gamma rays and neutrons. The… 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.
