Abstract:A NOVEL APPROACH TO LOW COST SHAPED BEAM SCANNING FOR MONOLITHIC STRUCTURES IS PROPOSED. THE TECHNIQUE MAKE USE OF RADOME MATERIAL COSTING OF THE CONVENTIONAL MONOLITHIC STRUCTURE; THE RADOME ITSELF IS COMPOSED OF A COMPOSITE OF HIGH DIELECTRIC CONSTANT/MAGNETICALLY SENSITIVE MATERIAL-REFERED TO AS… more
Abstract:Due to the limited space and the need for flush mounting charactistics, a new and novel series of antenna systems for communications and ECM is proposed. It is proposed to use dielectromagnetic (DM) materials to miniaturize antennas and for RF DM lens to focus the RF signals into the below the… more
Abstract:Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transmitted or received, i.e. one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency nulls begin to… more
Abstract:THE NETWORK ARCHITECTURE SPEECH SYSTEM (NASS) UTILIZES A NEW APPROACH IN PROVIDING EXCELLENT ACCESS FOR VISUALLY IMPAIRED PEOPLE TO OFF THE SHELF PROGRAMS (E.G., WORDPERFECT, LOTUS 1-2-3) THAT RUN ON THE IBM PC, AT, PS/2, AND COMPATIBLES. IT DRAMATICALLY CHANGES THE CURRENT SENSORY ADAPTIVE AID… more
Abstract:The vibration signatures (mechanical, acoustic, and electromagnetic) produced by machine components may be used for machinery diagnostics. By regularly measuring vibration levels, defects can be detected and diagnosed before causing extensive damage or failure, a process known as predictive… more
Abstract:The position control of aircraft is inherently a two-point boundary-value problem, and aircraft rate and attitude control are desirably treated as such. The aircraft maneuvers from an initial state vector at a given initial time to a final state vector at a given or optimiized final time. The final… more
Abstract:THE EXTERNAL CONFIGURATION OF ADVANCED, LOW-OBSERVABLE AIRCRAFT HAVE EVOLVED TO INCLUDE CHINED FOREBODIES. AT THE SAME TIME, AGILITY REQUIREMENTS HAVE BEEN ADDED TO MANEUVER WELL INTO THE HIGH-ANGLE-OF- ATTACK REGION WHERE CONVENTIONAL CONTROLS ARE LIMITED. IT IS PROPOSED TO EXAMINE THE CAPABILITY… more
Abstract:THERE IS A NEED TO MANAGE BETTER THE INPUT OF POLLUTANTS WHICH ADVERSELY AFFECT THE AQUATIC ENVIRONMENT. ALTHOUGH MANAGEMENT PRACTICES CURRENTLY USED HAVE PROVIDED INFORMATION ON TOXICITY POTENTIAL THROUGH THE USE OF BIOASSAYS DONE ON DISCRETE SAMPLES, MORE VALUABLE INFORMATION WOULD BE AVAILABLE… more
Abstract:RESEARCHERS HAVE DEVELOPED AN ULTRASENSITIVE QUANTITATION SYSTEM TO BE USED WITH A LARGE FAMILY OF ISOTOPES. THIS SYSTEM SUPPORTS LABEL MULTIPLEXING; MANY CO-RESIDENT ISOTOPES IN THE FAMILY CAN BE QUANTITATED SIMULTANEOUSLY, ALLOWING EITHER THE POOLING OF LABELED SAMPLES OR THE POOLING OF DISTINCTLY… more
Abstract:The scattering of neutrons permits to obtain structural information about diverse biological materials and processes. The impact of new intense sources of cold neutrons may revolutionize this field because it permits real-time, in vivo neutron microscopy. Featuring spatial resolution better than… more
Abstract:We have developed an ultrasensitive quantitation system which can be used with a large family of isotopes. This system supports label multiplexing; many co-resident isotopes in the family can be quantitated simultaneously. This process allows either the pooling of labeled samples or the pooling of… more
Abstract:A LARGE DEPLETION OF ATMOSPHERIC OZONE IS OCCURRING EACH AUSTRAL SPRING OVER ANTARCTICA. REFERRED TO AS THE OZONE HOLE PROBLEM, THE CONCERN IS THAT OZONE-POOR AIR FROM THE ANTARCTIC STRATOSPHERE IS MIXING WITH AIR AT LOWER LATITUDES. FURTHERMORE, THERE ARE INDICATIONS THAT THE SIZE OF THE HOLE COULD… more
Abstract:A THEORETICAL PROGRAM IS PROPOSED TO INVESTIGATE A COMPACT, LOW-VOLTAGE INFRARED GRATING LASER WITH MULTI-KILOWATT OUPUT CAPABILITY. THE RADIATION IS GENERATED BY THE PASSAGE OF AN ANNULAR BEAM OF ELECTRONS THROUGH A COAXIAL PAIR OF CONDUCTORS, THE INNER CONDUCTOR BEING A CORRUGATED CYLINDER WHICH… more
Abstract:This receiver sets forth a plan to utilize commercial GPS receivers for real time ionospheric prediction at a remote location. The project will demonstrate the feasibility of using TEC measurements and evaluate the accuracy and applicability of these measurements for improvements in HF propagation.… more
Abstract:This proposal sets forth a plan to analyze and archive ionosonde data. Large amounts of ionosonde data have been collected and are still being collected in analog form. We propose to design and develop a scanner which will accept these analog data, interpret them and finally archive the ionospheric… 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.
