Abstract:An observer of a continuously moving visual scene has induced a reflexive eye movement called nystagmus. Nystagmus signals are termed optokinetic (vestibular) if induced by visual stimulation (head rotation or other stimulation of the vestibular system). These responses are important in flight and… more
Abstract:The long-term objective is to develop a microcomputer-based education product for youth, tentatively titled MYFITE for Life¿ (MYFITE¿), to give youth a "fighting chance" in substance use and abuse prevention and treatment. MYFITE is based on the Fitness Intervention Training (FIT) model, a "life… more
Abstract:THE OBJECTIVE IS A COMPACT, RELIABLE AND INEXPENSIVE METHOD FOR SAMPLING LARGE VOLUMES OF AIR RAPIDLY TO DETERMINE THE CONCENTRATION OF AIRBORNE EXPLOSIVES. THE APPROACH INVOLVES THE USE OF A MULTIVORTEX PRECIPITATOR CAPABLE OF EFFICIENTLY REMOVING FINE PARTICULATES AND LARGE MOLERCULES FROM THE AIR… more
Abstract:HyperBaric Oxygen (HBO) medical treatment therapy is performed on humans in presurrized chambers. The chambers are operated by a trained technician that directs the chamber systems fro a console. The operator monitors the chamber parameters, the patient's physical condition and controls the… more
Abstract:HyperBaric Oxygen (HBO) therapy is a proven treatment for numerous medical conditions. HBO therapy is based on the premise that oxygen at pressure greater than atmospheric provides enhanced healing. The major cost component of any HBO treatment center is the structure that contains the elevated… more
Abstract:Since 1986, ENTECH, NASA, and SDIO have pioneered the development of refractive space photovoltaic concentrator systems. We have developed functionally system hardware, including lenses, prismatic cell covers, single- and tandem-junction cells, and small arrays. This hardware has verified… more
Abstract:TECHNOLOGICAL ADVANCES HAVE PLACED GREATER DEMANDS ON ABILITY TO MAINTAIN TOLERANCES ON SIMULATOR SUBSYSTEMS (E.G., RESPONSES OF VISUAL AND MOTION BASE SYSTEMS AND THEIR INTERACTION). A SYSTEM TO RECORD VISUAL SCENES IN FLIGHT SIMULATORS, WHICH INCLUDES MAN-INTHE-LOOP, IS NEEDED FOR RDTE AND… more
Abstract:THE ACCELERATING TEMPO OF MILITARY OPERATIONS INCREASES THE TASK DEMANDS AND WORK RELATED STRESSES IMPOSED ON HUMAN OPERATORS. AS NEW TECHNOLOGICAL DESIGNS ARE INCORPORATED INTO MILITARY SYSTEMS, A METRIC IS REQUIRED TO ENSURE THAT HUMAN COGNITIVE WORKLOAD LIMITS ARE NOT EXCEEDED. SOME PROGRESS IN… more
Abstract:ISOPERFORMANCE METHODOLOGY IS A SET OF FORMAL RELATIONS (TRADE-OFF FUN CTIONS) AMONG THE DETERMINANTS OF PERFORMANCE; IT IS DERIVED BY FIXING A DESIRED LEVEL OF PERFORMANCE AND THEN SOLVING FOR COMBINATIONS OF THE DETERMINANTS SUFFICIENT TO PRODUCE THAT LEVEL. THE ISOPERFORMANCE IDEA IS NOT ORIGINAL… more
Abstract:Our industrialized society places a premium on the visually-based ability to resolve fine-spatial detail in the environment. But the perceptual demands of new aircraft display systems, and indeed the tasks of out-the-window performances (landing, low-level attack, etc.) in aviation may involve… more
Abstract:In this project FASTMAN will determine the feasibility of using fractal and wavelet signal preprocessing in conjunction with neural network pattern classifiers on high-range resolution radar data for detecting cold stationary ground targets in a clutter-rich environment. Previous researchers have… more
Abstract:INFORMATION IS A VALUABLE COMMODITY IN TODAY'S SOCIETY AND THE AMOUNT OF INFORMATION IS INCRASING AT A PHENOMENAL RATE. AS A RESULT, THE ABILITY TO STORE, ACCESS, AND TRANSMIT INFORMATION IN AN EFFICIENT MANNER IS BECOMING CRUCIAL. IN THE TELECOMMUNICATIONS INDUSTRY, NEWLY-EMERGING VOICE AND IMAGE… more
Abstract:A lens system even if very complicated, when computer simulated (i.e., in a "virtual reality") will function, under appropriate circumstances, as if it were real. This system requires coherent illumination of the target, so a laser or microwave source is needed, but a microchip would do the focusing… more
Abstract:SUPERLATTICE BASED ACOUSTIC WAVE DEVICES WILL FORM THE BASIS OF A MAJOR BREAKTHROUGH IN THE FIELD OF RF FILTERS, RF SIGNAL PROCESSING, AND RF FREQUENCY SOURCES. THIS TECHNOLOGY SHOULD MOVE THE MAXIMUM OPERATING FREQUENCY FOR SURFACE ACOUSTIC WAVE DEVICES WELL INTO THE MICROWAVE RANGE BY OVERCOMING… 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.
