Abstract:AS PAVEMENT MANAGEMENT SYSTEMS BECOME THE PRIMARY TOOL BY WHICH AGENCIES ALLOCATE THE FUNDS FOR PAVEMENT REHABILITATION, THE ACCURACY OF DISTRESS DATA. ONE OF THE LEAST EXPENSIVE BEING MANUAL DISTRESS SURVEYS. HOWEVER, MANUAL DISTRESS SURVEYS HAVE THEIR LIMITATIONS. INACCURACIES THAT ARISE IN THE… more
Abstract:We will develop a computer program for automating the testing of medical diagnostic imaging equipmeprogram will run o the vast majority of existing PACS computers which many radiology departments alrdevelopment will provide testing methods for most medical image quality parameters which are much… more
Abstract:A novel quantum well infrared photo transistor, which we call QWIPT, is proposed. By taking the advantage of the almost perfect alignment of the conduction band in GaAsSb/InAlAs system, it is possible to integrate such quantum wells into a QWIPT to improve the optical gain and, therefore, the… more
Abstract:Commercial tools have been developed that support the graphical construction of behavioral models of reactive systems and implement various forms of analysis of such user-developed models. These methods rely primarily on simulation, that is, the execution of a model on sample data. We propose to… more
Abstract:A fuzzy logic and artificial neural network (ANN) hybrid software model of vestibular system function will be investigated to improve assessment of the vestibular systems. Recent advances in fuzzy logic and ANNs have provided new modeling techniques to narrow the gap between the model and real… more
Abstract:The auditory brainstem response (ABR) is one of several auditory evoked responses which have a variety of military and clinical applications (2,6). Currently the ABR is analyzed using frequency-dependent filtering techniques over very long windows (up to several hundred seconds). CMI proposes to… more
Abstract:This project represents the potential for a major advancement in helicopter fire fighting capability for forests and grasslands. Although early work with helicopters attempted to maximize the quantity of water delivered for initial fire attack, the Light Aircraft Foam Application System (LAFAS)… more
Abstract:The determination of the angular orientation of a radar or electro-optic assembly almost always involves the use of gyros. Except for very crude applications, gyros are always used in conjunction with accelerometers, their combination being referred to as an Inertial Measurement Unit or IMU. Gyro… more
Abstract:Until recently, polymer coatings were stripped from aluminum alloys using volatile organic compoound solvents. This is being phased out for environmental reasons. Mechanical techniques like PMB also have severe environmental impact. New methods need to be explored. The approach in this proposal… more
Abstract:MODERN SENSORS PRODUCE VAST AMOUNTS OF SIGNAL INFORMATION WHICH MUST BE PROCESSED QUICKLY AND ACCURATELY TO PERFORM SURVEILLANCE AND TARGET TRACKING FUNCTIONS. PREPROCESSING OF THE SENSOR DATA IS PERFORMED FIRST TO REMOVE BACKGROUND SIGNALS, DETECT SPIKES AND PEAKS, FILTER THE SIGNAL, ENHANCE EDGES… more
Abstract:Many presently fielded weapons systems as well as systems on the drawing boards, must transmit and store large volume sof digital data generated by electro-optic (EO), imaging infrared (IIR), millimeter wave (MMW) and fiber optic guidance systems. Real time data compresson offers the advantage of… more
Abstract:The Navy is developing the Cooperative Engagement Capability (CEC) communications network to allow ships to share air defense radar and fire control data among a battle group. Current problems in the CEC's communication links are: the power required to meet operational specifications is higher than… more
Abstract:A programmable fiber optic delay line system for microwave signal storage will be designed and analyzed, and optical switch technology for use in the system will be perfected. The delay line will consist of fifteen 2x2 optical switches connected by single mode fiber sections of unequal length. A… more
Abstract:The Personal Motion Platform (PMP) is designed to be used with Virtual Environment Training (VET) systems to support Intra Vehicular Activity (IVA) and Extra Vehicular Activity (EVA) training development of astronauts. The trainee is supported in a modified neutral body posture that closely… more
Abstract:RGI proposes to demonstrate through analysis the feasibility of using modified versions of the proven OMAR (Optical Microwave Approach and Ranging) technology to enhance the reliability and survivability of UAV's by using the OMAR technology for UAV, IFF, tracking and flight commands for evasive… more
Abstract:Military and civilian pilots are vulnerable to glare. A terrorist with a laser can light up an entire canopy. If landing, the plane could crash. In action, a twenty million dollar aircraft would be neutralized by a ten thousand dollar, off-the-shelf item. Glare arises from three sources: 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.
