Abstract:We will use an innovative neural network algorithm to perdict and control National Aero-Space Plane(NASP) unstarts at the earliest possible moment. Unstarts present a design challenge to hypersonic aircraft. An unstart occurs when the pressure at the aft end of the engine flow path reaches a… more
Abstract:During Phase I we will advance and develop innovative Adaptive Critic based neural network control methodologies specifically for a Remotely Piloted Vehicle (RPV) based upon the aerodynamics of the National AeroSpace Plane (NASP). Phase II will involve the actual implementation which will prove… more
Abstract:This project will develop a neural network based Figure of Merit or Target Quality Subsystem for use in Carrier and Amphibious Assult Ship Air Traffic Control Subsystem. This system will take sensor data from multiple sensors into the subsystem and determine the actual target location. This will… more
Abstract:We will design a flowpath and a neural network based propulsion system controller for LoFlyte I, a remotely piloted vehicle (RPV) based upon the aerodynamics of the National AeroSpace Plane (NASP). This work will be the first step to a highly innovative RAM/SCRAM propulsion system and to a… more
Abstract:The purpose of this proposal is to develop a new generation of "SMART" neurocontrol actuator systems for use on hypersonic aircraft. Develop a testbed to see that the actuator system will work. This will also optimize and scale the testbed vehicle sizing. This concept using adaptive neural network… more
Abstract:The manufacture of composite materials for use as high confidence components in aircraft has resulted in a requirement for rigorous defect analysis. This proposal researches the use of neural network technology combined with Laser Ultrasonics to provide the quality assurance inspector with the… more
Abstract:This research effort investigates the use of a passive tracker combined with the appropriate "neural network" or "heuristic" assessment system to determine whether a missile fired at an aircraft is on a collision course. The results of this study will outline a system concept which can be used to… more
Abstract:RECENT WORK IN VOLUME HOLOGRAPHY HAS LED TO THE DISCOVERY OF THE ORTHOGONAL DATA STORAGE TECHNIQUE. THIS METHOD OF HOLOGRAPHIC DATA RECORDING REDUCES THE CROSSTALK BETWEEN CHANNELS BY STORING MANY WAVELENGTH MULTIPLEXED IMAGES IN A PARTICULARLY EFFECTIVE USE OF K-SPACE. FURTHER REDUCTION IN… more
Abstract:BBO AND LBO CLASS MATERIALS WERE STUDIED FOR POSSIBLE APPLICATION AS UV-SENSITIVE PHOTOREFRACTIVE MATERIALS. UNDOPED SAMPLES OF BBO AND LBO WERE DOPED BY HIGH TEMPERATURE DIFFUSION WITH VARIOUS TRANSITION METAL SPECIES TO DETERMINE THEIR SUITABILITY FOR STORING HIGH EFFICIENCY HOLOGRAPHIC GRATINGS.… more
Abstract:Narrow bandwidth filters using holographic reflection gratings will be developed for application in solar atmospheric studies, where rapid wavelength tunability over about a 1 A range is required. A holographic grating filter for monochromatic imaging at the Ha line has already been demonstrated by… more
Abstract:This SBIR project will bring about a major advance and improvement to existing meteorological data systems by utilizing new technological opportunities to develop a meteorological workstation merging data and graphics products from multiple independent systems to yield a single display system that… more
Abstract:In the field of seismic event identification, three spatial dimensions and one time dimension are almost always coupled together. This may create confusion in data perception and interpretation. A novel multi-D display device wchih can improve data visualization is needed. The object of this project… more
Abstract:THIS NATION HAS MORE THAN 11 MILLION MANHOLES WHICH NOW NEED, OR SOON WILL NEED, TO BE REHABILITATED. CURRENT TECHNIQUES ARE EITHER TOO COSTLY OR DO NOT LAST. THIS RESEARCH SPEAKS TO THIS PROBLEM THROUGH DEVELOPMENT OF AN INNOVATIVE TECHNIQUE OF RESTORING MANY OF THESE STRUCTURES AT LESS THAN HALF… more
Abstract:We will extend recent observations regarding the discovery and characterization of alloreaction-a-ssociated antigen (ARAg), a novel member of the immunoglobulin gene superfamily selectively expressedon leukocyte subsets. ARAg surface expression is increased on T lymphocytes in response to allogeneic… more
Abstract:The proposed effort investigates the use of smart materials (such as strain actuators and sensors) and modern control theory to suppress unsteady buffet loads encountered by vertical tail aircraft such as the F/A-18. The active smart material system proposed has distinct advantages over traditional… more
Abstract:A high repetition rate mid infrared laser (3-5 microns) capable of providing multispectral output covering all bands used by infrared missile would make a solid state laser based IRCM system a potentially attractive replacement for black body infrared jammers. We propose a novel laser concept that… 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.
