Abstract:ATMOSPHERIC SCIENCE PLATFORMS OF ALL TYPES REQUIRE A RELIABLE AND COST-EFFECTIVE MEANS OF COMMUNICATING WITH HOME LABORATORIES. CURRENT SATELLITE TECHNIQUES SUFFER FROM LOW DATA RATES, EXCESSIVE LATENCIES, HIGH COSTS, OR OTHER COMPLICATIONS. A NEW GENERATION OF LOW-ALTITUDE COMMERCIAL DATA RELAY… more
Abstract:Knowledge of the vertical profile of atmospheric parameters can be an important factor in determining the operational effectiveness of many military and civilian systems. For the past three years Aurora Flight Sciences has used support from the National Science Foundation to develop a lightweight… more
Abstract:A versatile, low-cost satellite data link is proposed for use aboard manned or robotic environmental research aircraft. The link will allow remote users to access data aboard,the aircraft via a remote- file server, as well as to control instruments or even (with correct access privileges) the… more
Abstract:Aurora Technologies Corporation (Aurora) proposes to develop a new high-performance, room temperature detector and array technology that will allow NASA to investigate phenomena of considerable significance to space astronomy, astrophysics, geophysics and atmospheric studies throughout nearly the… more
Abstract:The contract will develop a Shoulder Launched unmanned Reconnaissance System (SLURS) that can be carried, launched and flown by a single soldier. The system consists of a Reconnaissance Air Vehicle (RAV), Launcher, a Ground Control Subsystem (GCS), and several Individual observer Units (IOU). A… more
Abstract:In the proposed work a complete elastic porous material theorywill be used as a basis for developing the first two-dimensionalacoustical finite element model of noise control foams. Althoughfoams are widely used for passive control of aircraft andaut
Abstract:The International Normalized Ratio (INR) is designed to standardize the reporting of prothrombin timeasurements in patients taking warfarin. To appropriately manage patients taking anticoagulants, abe achieved between too much or too little anticoagulation, which can respectively result in… more
Abstract:THE MICROSOFT WINDOWS NT (NEW TECHNOLOGY) OPERATING SYSTEM, RELEASED IN THE SECOND HALF OF 1993, IS TOTALLY INACCESSIBLE TO VISUALLY IMPAIRED STUDENTS AND BUSINESS PROFESSIONALS. THIS OPERATING SYSTEM WILL BE IN MANY COLLEGES AND UNIVERSITIES FOR SCIENCE AND MATH COURSES AND WILL SEVERELY HINDER… more
Abstract:Today many robots are being applied in areas where accurate positioning and orientation of the robot end-effector is required. A practical approach to achieve accurate positioning of the robot end-effector is through the use of an external measuring system. In 1986, a 3-D and 6-D laser tracking… more
Abstract:This proposal addresses development of CAD software for simulating non-linear optical materials. The software will provide a virtual lab in which experimental setups are simulated. The proposed software is based on the use of a Maxwell differential equation solver, the Finite Difference Time… more
Abstract:Current Distributed Interactive Simulation (DIS) environments permit mechanized units to fight on a simulated battlefield. Participants in the simulated battle sit inside of physical mock ups of vehicles and engage both real and simualted opponents. The current DIS environments do not address a key… more
Abstract:Magnetic bearings offer substantial advantages over conventional bearings in high speed and high temperature rotating machines, such as gas turbine engines, in that they do not require oil for lubrication. However, before advanced magnetic bearings can be considered for use in military and… more
Abstract:Improved replication of vaccine seed strains in embryonated hens' eggs would lower the cost of manuinactivated influenza vaccines and allow more doses to be manufactured. Higher-growing influenza A aviruses will be developed that can be genetically reasserted with poorly-growing fresh human… more
Abstract:This project will investigate the use of Laser Raman Infra-Red Fiber Optic Sensor to remotely determine the chemical characteristics of advanced composite materials. The proposed research will investigate a means to measure and manage the composition and cure state of the resin matrix during an… more
Abstract:This project will develop and demonstrate a design for a wavelet-based compression system that will support the tranmission of video and still data bia UHF satellite communication channels and twisted-pair cuircuits. The system will feature real-time teleconferecing and the ability to rapidly… more
Abstract:Subclutter visibility may be achieved using wavelets and wavepacket methodss. Wavelets offer the ability to separate features based on scale. Wavepackets and the best-basis algorithm offer the further advantage of adaptability; bases adapt to the signal to provide optimum signal representation. We… more
Abstract:Digital imagery is an increasingly prevalent in the computerized workplace; however, the increasing volume of this data is stressing storage and communications systems. One of the most competitive solutions to these stresses is wavelet-based data compression. A wide variety of wavelet image… more
Abstract:The potential to reduce US Army tactical generator set weights and sizes will be explored through the combined application of High Frequency Alternators and Power Frequency Converters. The application of such technology will improve the mobility and deployability of the tactical equipment as… 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.
