Abstract:This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative… more
Abstract:This project will identify and develop new low cost high thermal performance coating systems for composite thermal management materials, particularly high conductivity carbon-carbon. Three materials/processes will be investigated including a new type of chemical vapor deposition called combustion… more
Abstract:The new joint mission scenarios and stealth interdiction objectives for the U.S. Navy have resulted in the need for improved sensor systems for operations in the littoral environment. A High Frequency Towed Array (HFRA) sonar system, operating in the same frequency band as hull mounted systems,… more
Abstract:Significant advances have been made over the past few years in all optical arrays. Low cost optical sensors have been produced and demonstrated along with optical telemetry capable of multiplexing many sensors onto a single optical fiber. Although the new optical sensors and telemetry designs … more
Abstract:Special Operations Forces (SOF) require a real time display of appr opriate data to allow the helmsman to access the damage potential to his cargo (equipment/personnel) and support his decision relative to speed and course selection when operating in rough water. Furthermore, maintenance support… more
Abstract:The extensive use of heavy metals in prior industrial/military operations has resulted in numerous sites with soil/groundwater contamination. Phytoremediation research has shown that plants can successfully uptake heavy metals from contaminated sites. Recent research on phytoremediation of heavy… more
Abstract:The proposed Phase 1 approach utilizes a material system, the I-III-VI2 compounds, for which some early success in the fabrication of laser devices and LEDs has been achieved in Japan. The benefits to this material include: ease in forming p-n junction, greater thermal conductivity, higher bond… more
Abstract:The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques… more
Abstract:Under the proposed research an Interface-Driven Design Manager (IDM) for CAD packages will be developed to greatly reduce the design cycle time for aircraft structures. The IDM represents a first attempt to fully integrate powerful new interface element and design management technologies into the… more
Abstract:Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their… more
Abstract:Warhead design calculations and weapons effectiveness estimates require a methodology to predict structural response and the associated damage to air targets from reactive munitions. The objectives for the proposed Phase I study effort are to develop candidate launch conditioning, reaction… more
Abstract:Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or… more
Abstract:The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper… more
Abstract:EXPOSURE OF BLOOD TO AN ARTIFICIAL SURFACE USUALLY LEADS TO THE ACTIVATION OF THE INTRINSIC PATHWAY OF THE PLASMA COAGULATION CASCADE AND TO THE ACTIVATION OF PLATELETS, WHICH ARE OFTEN ACCOMPANIED BY THE FORMATION OF A THROMBUS, OR BLOOD CLOT. A POPULAR TECHNIQUE FOR IMPARTING THROMBORESISTANCE TO… more

Abstract:Unexpected coupling between nuclear reaction cross sections and the solid state of metal deuterides has been demonstrated in layered Pd-PdO deuterided structures. As a result, high rates of charged particle and neutron measurements have been observed through a reaction initiated by altering the… 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.
