Abstract:THE CURRENT FIVE-POINT MILITARY AVIATION RESTRAINT SYSTEM (FOR NON-EJECTION CREW SEATS) WHEN PROPERLY USED (I.E., TIGHTLY ADJUSTED), CAN PROVIDE GOOD OCCUPANT CRASH PROTECTION. THE RESTRAINT SYSTEMS ALSO INCLUDE AN INERTIAL REEL ON THE SEAT BACK WHICH IS DESIGNED TO LOCK THE SHOULD STRAPS AT THE… more
Abstract:This proposal concerns the development of procedures and software for implementing the Dynamic Flowgraph Methodology (DFM), a methodological approach to modeling and analyzing software-based control systems for the purpose of reliability/safety assessment and verification. Using DFM, models… more
Abstract:Reliability and performance are critical characteristics of the Army's avionics systems. These systems must meet stringent requirements in the areas of: (1) dispatchability, or operational readiness to support missions; (2) dependability, or the ability to perform critical functions correctly during… more
Abstract:Future battlefields will require independent operations and increased operational tempo, placing severe burdens on weapons platform crewmembers in the areas of information flow management, data fusion, and assessment of data to arrive at the most tactically acceptable decisions. Work continues in… more
Abstract:Reuse in software engineering is an exciting concept that has yet to be reliably implemented. The number of program subroutines that are truly generic (and therefore applicable across all applications) is limited. However, there are specific applications that are required by many organizations,… more
Abstract:The field training of Reserve Component units is difficult because of limited training time and facilities and the difficulty in assembling all necessary player personnel. Computer wargames which allow interactive play of player personnel are a relatively inexpensive alternative and supplement to… more
Abstract:Alzheimer's disease (AD) is a common, devastating neurodegenerative disorder characterized by progrcognitive decline. Loss of the cholinergic innervation of limbic structures and the neocortex occursin patients with AD. The degree of cognitive decline has been correlated to the extent of… more
Abstract:Manual welding operations remain totally dependent on the instincts of the operator and the operator's ability to collect information through normal sight and sound. The proposed innovation will apply modern data presentation technology to enhance the welder's perception of the welding situation.… more
Abstract:The Discrete Wavelet Transform (DWT) is a Time-Frequency Distribution (TFD) which offers the potential to efficiently characterize both transient and global intrapulse signal features in a highly compressed format. The overall objective of this three phase effort is to develop Wavelet analysis as a… more
Abstract:IN ACCORDANCE WITH THE HAZARDOUS MATERIALS TRANSPORTATION UNIFORM SAFETY ACT OF 1990 (HMTUSA), DOT IS NOW REQUIRED TO CREATE A CENTRALIZED DATABASE OF STATE-DESIGNATED HAZARDOUS MATERIAL HIGHWAY ROUTES. DOT IS ALSO RESPONSIBLE FOR PERIODICALLY UPDATING AND PUBLISHING A LIST OF CURRENLY EFFECTIVE… more
Abstract:Marine storms strongly affect operations at sea, both DoD and commercial. The DMSP SSM/I clearly depicts certain features of marine storms. Improved depiction of these storms will aid nowcasting in support of execution.of operations at sea and fore- casting of the evolution of these storms in… more
Abstract:The proposed program utilizes advanced radar technology to develop a fuze for penetrating weapons. The technology is the result of Aeres efforts in the analysis and design of Ground Penetrating Radars. The unique approach utilizes millimeter-sized impulse diodes to develop extremely short… more
Abstract:The objective of this project is to implement and demonstrate a comprehensive physical model and practical computation tool for predicting/analyzing soot formation due to hydrocarbon-fuel combustion is liquid-propellant rockets. A state-of-science approach is proposed for understanding/ quantifying… more
Abstract:EXISTING CONTROL SYSTEMS FOR PITCH-CONTROLLED WIND TURBINES STABILIZE ROTOR POWER BY ADJUSTING BLADE PITCH IN RESPONSE TO OVER-OR-UNDER POWER CONDITIONS IN A FEEDBACK LOOP. THE PITCH CONTROL MECHANISM LAGS BEHIND THE ROTOR POWER VARIATIONS THAT ARE BEING CONTROLLED. THE TIME LAG CAUSES POWER… more
Abstract:WORLD-WIDE WIND VELOCITY, BOTH SPEED AND DIRECTION, FROM THE GROUND THROUGH 50,000 FT. ALTITUDE CAN BE ACCURATELY MEASURED USING A SMALL SPACE-BASED PAYLOAD. THE PROPOW=SED PROJECT WILL DEMONSTRATE THAT RECENT DEVELOPED LASER, DETECTOR AND SPACECRAFT TECHNOLOGIES CAN BE EXPLOITED AND INTEGRATED INTO… more
Abstract:Construction of a very small (~1 kg) satellite bus compatible with the requirements of a 3 axis controlled satellite mission is presently technically feasible. Such systems have been discussed, but none have been realized yet because of technology and cost considerations. Such a satellite would have… more
Abstract:A NOVEL METHOD, SUPERSONIC VIRAL IMPACTION, IS BEING INVESTIGATED TO SEPARATE AND COLLECT FINE, SOLID PARTICLES FROM GASES. THE MAIN ADVANTAGES OF THE METHOD ARE: SEPARATION OF PARTICLES FROM HOT, CHEMICALLY AGGRESSIVE, CONDENSIBLE CARRYING GASES WHILE PRESERVING THE PARTICLES FROM CONTAMINATION BY… more
Abstract:The excitation of structural vibrations by turbulent boundary layer surface pressure fluctuations is an important problem in underwater acoustics. A capability for accurately characterizing these fluctuations, especially the low wavenumber components of the spectrum, is needed to determine the… more
Abstract:The process of designing and evaluating advanced aircraft coatings can be made more efficient, more robust, and less expensive through application of highly accurate and flexible computer models. The General Scattered Light (GSL) model is such a signature analysis tool, but its potential is… 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.
