Abstract:A program is proposed to develop data processing routines for adaptive optics. These routines will be such that they run on a PC, such as a 486, and are compatible with commercial software packages, such as MATLAB, Matrix X, or Control C. A key feature of this work is the breadth of experience that… more
Abstract:Our company will create a software "tool" to characterize aspects of the structure andperformance of the larynx from analysis of speech. The analysis relies on the theory of nonlineardynamical systems, or "chaos theory". It provides parameters (Lyapunov exponents, metric entropy,attractor… more
Abstract:It is clear that the utility of tactile aids degrades even more rapidly in the presence of noise than is the case for hearing aids. This is particularly apparent in the integration of visual and tactile cues as for example in speechreading. One reason may be is because many of the cues derived from… more
Abstract:We will develop low cost, wireless instrumentation to monitor the frequency and duration ofbody turning by elderly nursing home residents who are bedfast and clinically at risk for the developmentof pressure sores. This instrumentation should facilitate both the better diagnosis of 'at risk'… more
Abstract:Safety-critical aerospace applications have become increasingly dependent on a software component. However, conventional approaches to increasing the software reliability of these systems have focused on purely programming aspects. While these methods can all lead to techniques which should minimize… more
Abstract:The objective of the proposed program is to develop a widefield narrowband optical filter (WNOF) for use in laser radar receivers. The WNOF provides the necessary discrimination against strong solar bandground that limits the daytime performance of the laser radar system. The proposed approach is… more
Abstract:The objective of this project is to develop, test and demonstrate the capability to identify individual soldiers through the use of cooperative and/or non-cooperative techniques. The offset will emphasize particularly the identification of friendly forces using cooperative techniques. The process… more
Abstract:Unmanned aircraft and lightweight instruments are a dual-use technology that offer dramatic new opportunities to both the atmospheric research community and to operational missions of the US Navy. Aurora Flight Sciences is the first company in the world to develop an unmanned aircraft, Perseus,… more
Abstract:When interpreting chemical changes from measurements made on moving platforms it is important to remove signatures due to the motion of the air. This has proved difficult on existing manned aircraft such as the ER-2, necessitating post-processing of the data prior to interpretation. Digital flight… more
Abstract:The recent availability of an entirely new gamma ray sensing material makes it possible todevelop a new nuclear imager for early detection of breast cancer. This small, lightweight imager maybe inserted in the position of a conventional mammography film plate to provide close registration ofnuclear… more
Abstract:The project goal is to develop an instrument for real-time monitoring of renal function for earlydetection of renal failure. Studies will be conducted with a phantom and with human subjects to validatethe instrument's effectiveness. If successful, the project is expected to provide the means for… more
Abstract:THE OVERALL GOAL IS TO DEVELOP LOW COST "SMART" SENSORS FOR HARD X-RAYS SUITABLE FOR USE WITH MINIMALLY INTRUSIVE EMPLACEMENT SYSTEMS SUCH AS CONE PENETROMETERS AND PORTABLE INSTRUMENTS. THE SENSORS WILL EFFICIENTLY MEASURE ENERGY SPECTRA UP TO 300KE V, AN IMPORTANT RANGE FOR SPECTROSCOPIC… more
Abstract:The overall goal is to develop an entirely new method of X-ray imaging to replace the current film-screen imager with a semiconductor detector array providing direct, digitized detection. The approach is enabled by this company's recent development of cadmium zinc telluride detectors and the… more
Abstract:The project will design personal computer software that is usable to nursing facility managers and others, such as health care professionals, consumer advocates, and placement specialists. It will make quality of care information available and analyze service pattern and staffing.
Abstract:The objective is to develop an artificial full-thickness corneal graft to replace damaged corneain millions of people who suffer from blindness due to damaged or diseased cornea. The specific aimsof Phase I are to fabricate prototype grafts composed of a clear, soluble collagen core surrounded by… more
Abstract:THERE IS AN INCREASED EMPHASIS ON THE ACOUSTIC SIGNATURES OF GROUND COMBAT VEHICLES DUE TO THE DEVELOPMENT OF NEW AND EFFECTIVE ACOUSTIC TARGET ACQUISITION SYSTEMS. DURING THE DESIGN STAGE OF A GROUND COMBAT VEHICLE, IT IS IMPORTANT TO REDUCE THE NOISE, EMITTED FROM STRUCTURAL COMPONENTS. THEREFORE,… 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.
