Abstract:SDIO HAS THE DIFFICULT PROBLEM OF FINDING TARGETS IN CLUTTER WITH PRACTICALLY NO TOLERANCE FOR ERROR BECAUSE OF THE AUTOMATED NATURE OF RESPONSE AND THE SHORT TIMES INVOLVED. TARGET RECOGNITION IN CLUTTER REQUIRES HIGH SPEED COMPUTATION AND THE OPTIMUM USE OF PARALLEL PROCESSING TO PRODUCE RESULTS… more
Abstract:This proposal seeks to establish the feasibility model for a high- performance inexpensive multi-band IR processor based on morphological signal processing, to be incorporated into the Navy's next generation of IR fuzes. Our unique processing approach is based on very simple computational circuits… more
Abstract:This proposal describes an innovative approach to the detection and discrimination of targets in multi-sensor airborne platforms. The major advantages of our process are: 1) substantial performance gains; 2) the use of a common architecture for multi-sensor platforms; and 3) the need for less… more
Abstract:It is proposed to develop and demonstrate a new signal processing approach for acquiring low contrast military targets in multi-band IR imagery. This new computationally efficient processing methodology has been shown to provide significant better detection/discrimination results in single-band long… more
Abstract:Because narrowband submarines emissions are constantly being reduced, one is forced to use broadband information to detect and track, still relying upon narrowband tonal energy for classification. In addition, broadband energy frominterfering sources such as biologics or profilers can clutter… more
Abstract:The objective of the proposed Phase I effort is to perform a preliminary design of an electronically scanned antenna capable of supporting a multimode radar testbed operating in MTI, ultra-high range resolution and SAR modes. The proposed baseline antenna concept consists of four major components: a… more
Abstract:A digital image processing system for ophthalmic applications will be developed. The system will enable users to quantify easily, quickly, and accurately various retinal lesions from retinal images. Lesions such as macular drusen exudates, cotton wool spot, hemorrhages, and aneurysms will be… more
Abstract:PITUITARY TUMORS COMPRISE ABOUT TEN PERCENT OF ALL BRAIN TUMORS. THE CLINICAL PRESENTATION OF THESE TUMORS IS DIVERSE, THE MORBIDITY AND MORTALITY IS HIGH, AND THE TREATMENT MODALITIES ARE INADEQUATE. LOADING PITUITARY CORTICOTROPHS AND SOMATOTROPHS WITH 10BORON LINKED TO EITHER CORTICOTROPHIN… more
Abstract:THE THREAT OF OZONE DEPLETION CAUSING INCREASED ULTRAVIOLET RADIATION AT MID-LATITUDES ON THE EARTH'S SURFACE, AND THE RESULTING HARM TO PLANT AND ANIMAL LIFE, HAVE PROMOTED THE U.S. DEPARTMENT OF AGRICULTURE TO ESTABLISH AN IMPROVED UV IRRADIANCE MONITORING PROGRAM, WITH EMPHASIS ON THE UV-B… more
Abstract:WE WILL DEVELOP A SYSTEM FOR REPRESENTING SPEECH USING TIME-VARYING CONTROL PARAMETERS FOR A SOURCE-FILTER MODEL OF SPEECH SYNTHESIS. WE WOULD EMPLOY TECHNIQUES OF ACOUSTIC ANALYSIS IN A KNOWN PHONETIC CONTEXT TO EXTRACT KLSYN88 SYNTHESIZER PARAMETERS FROM SPEECH WAVEFORMS. SUCH A SYNTHESIS-BASED… more
Abstract:THE PURPOSE OF THIS WORK IS TO DEVELOP IMPROVED METHODS FOR INCREASING THE SALIENCY OF ACOUSTIC SIGNALS FOR LISTENERS WITH LIMITED HEARING AND POOR FREQUENCY SELECTIVITY. THE LONG TERM GOAL IS TO DEVELOP WEARABLE AUDITORY DEVICES SO THIS POPULATION HAS A THIRD ALTERNATIVE FOR HEARING ASSISTANCE IN… more
Abstract:There exists a need for an effective Identification of Friend or Foe (IFF) as part of the target acquisition function in air and ground systems. The most important constraints applied to the real time IFF system include low probability of intercept, fail-safe, safe-guarded, and almost… more
Abstract:The program objective is to developand demonstrate a low cost, low probability of intercept (LPI) sensor technology for IFF of Unmanned Aerial Vehicles (UAV). Conventional approach using active microwave radars suffer from low angular resolution, high clutter, problem of electronic jamming and… more
Abstract:We will develop and test a light weight solid state imaging device (8x8 inches square) suitable for use in the operating room. Its specific application would be to assist the surgeon in locating tumor accumulations of radioactivity labelled monoclonal antibodies during surgical exploration. The… more
Abstract:THE ADOPTION AND FOSTER CARE ANALYSIS AND REPORTING SYSTEM (AFCARS) IS NATIONAL REPORTING SYSTEM WHICH IS CURRENTLY UNDER DEVELOPMENT. A WIDE RANGE OF PROBLEMS WILL BE EXPERIENCED BY STATES IN COMPLYING WITH THE COMPLEX AFCARS REQUIREMENTS. TO ASSIST STATES IN MEETING THESE REQUIREMENTS, FLEXIBLE,… 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.
