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
Abstract:New materials such as continuous fiber reinforced aluminum matrix composites exceptional performance, but often at the expense of incompatibility with conventional joining techniques. Spacecraft structures require high stiffness for stable structures and launch vibration resistance, as well as low… more
Abstract:The development of a microwave curing method for resin matrix composites and jointing/bonding epoxy is proposed. This technique will take advantage of the ability of vapor-grown carbon fiber (VGCF) to absorb microwave energy with high efficiency. By adding VGCF to resin matrix composite material and… more
Abstract:AVI proposes to develop a software application that will greatly improve both the effiency and timeliness of monitoring the security of complex C4T information networks and databases. The software will provide an interactive 3 dimensional picture of network status and activity that relies on… more
Abstract:Algal toxins can cause mass mortality of wild and farmed fish, contaminate shellfish beds and cause human illnesses from consumption of these products. Dinoflagellates are widely recognized to be the primary algae associated with toxic red tide blooms. Once established, harmful algal blooms… more

Abstract:This Small Business Innovation Research Project will determine the advantages and disad-vantages of fibrous/polymeric composite materials over traditional material (steel) for retrofitting key civilian facilities against terrorist bomb attack. Retrofit techniques we will evaluate are: … more
Abstract:We propose to develop a computer-based adaptive tutor to improve the reading comprehension skills of adult readers. Our instructional strategy is based on the Reciprocal Teaching method, demonstrated to improve reading comprehension. The "scaffolded" Reciprocal Teaching method demonstrates… more
Abstract:In complex human-machine systems such as military command and control (C2), corporatestrategic planning, air traffic control, and computer-supported collaborative work, the scope and complexity of the task often require that the decision-making function be distributed over several humans organized… 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.
