Abstract:The frictional losses in a gear mesh can be reduced by including super-finishing in the final manufacturing process. Phase I simulation tests of a hypoid rear axle gear shows a reduction in traction coefficient of 50 percent from an"as ground"surface to a high quality super-finished… more
Abstract:ABSTRACT: Incomplete and inconsistent impregnation of fiber beds in composite material manufacture jeopardizes the performance of multiple aircraft platforms and substantially increases acquisition and sustainment costs for the Air Force. Current test methodologies are inadequate to address this… more
Abstract:We propose a rapid mapping and 3-D visualization system especially suited for inside buildings, tunnels, urban"canyons", and other environments where GPS may be poor or not available. The system--which was fully demonstrated in our Phase I effort-- includes mobile Sensor Nodes that… more
Abstract:Although global pose is essential for success in certain vehicle missions and tasks, when GPS is denied there is no single technology (source) that can robustly estimate global pose without suffering from one or more failure modes. We propose to design an architecture that provides robustness by… more

Abstract:The deflagration/combustion efficiencies of impact initiated metal powders such as aluminum and tungsten when used in various types of ordnance to produce deflagration and momentum properties are significantly lower than desired and theoretically possible. The objective of this phase I SBIR effort… more
Abstract:Many of the protective measures against vector borne threats that are currently used by the military have significant issues. Personal protective measures often contact skin directly, causing adverse effects, such as rashes and irritations that are uncomfortable and can distract and/or debilitate a… more
Abstract:The U. S. Navy is seeking novel survival rafts for Navy pilots that may have to ditch at sea. The technology currently utilized have inflated gas compartments, generally carbon dioxide, that provide the necessary buoyant forces to keep the raft and its pilot afloat. This foundational technology, (i… more
Abstract:Helicopter flight in support of military operations is often conducted at night under low light conditions, where loss of situational awareness can lead to accidents such as controlled flight into terrain (CFIT). Current terrain sensing systems used to aid pilots in maintaining situational awareness… more
Abstract:The objective of the proposed program is to use advance manufacturing processes, to form near-net shaped (NNS) titanium wheeled hubs for tactical vehicles. Three manufacturing routes will be investigated including casting and two powder metallurgy processes based on Summit Materials Shaped Hot… more
Abstract:Achieving robust autonomy by demonstration is challenging for several reasons. First, it is important to be able to provide demonstrations in a way that they capture the key aspects of robot interaction with environment. Second, the interface for providing demonstrations needs to be friendly enough… more
Abstract:High performance steels were developed in a cooperative program between the Federal Highway Administration (FHA), the American Iron and Steel Institute (AISI), and the U.S. Navy Carderock Division of the Naval Surface Warfare Center. HPS70W high strength steel is currently being used in bridge… more
Abstract:The Climate Change Information System for Business and Industry (Climate Biz) will translate information derived from climate model simulations into industry-specific formats that will assist private sector executives and their firms to meet the challenge of climate change and thereby prosper in the… more
Abstract:ABSTRACT: Carbon fiber reinforcements pre-impregnated with resin (prepregs) are growing as a base material for many aerospace products. As such, prepreg quality is ever important and a key quality metric is its level of impregnation (LOI). However, high tolerance of prepreg LOI is difficult for… more
Abstract:ABSTRACT: The objective of the work proposed herein is to develop innovative physics-based models facilitating the accurate prediction of solid rocket propellant behavior with varying environmental boundary conditions. Our objective is to design and develop a theoretical framework for the… more
Abstract:Currently there is no tactical decision aid (TDA) for magnetic anomaly detection (MAD). Since the P-8A has no MAD capability, the planned approach to the localization phase of anti-submarine warfare (ASW) is to have the P-8A launch a MAD-equipped unmanned aerial vehicle (UAV). However, the mission… more
Abstract:This small business innovation Phase I project aims to develop a robust architecture for an attention based visual system for autonomous vehicle applications. Such a system is a critical front-end component for highly cognitive systems that can recognize objects and extract scene semantics from high… more
Abstract:Wind farms located within the line of sight of airborne radar systems can degrade the ability of the radars to perform their intended function of detecting and tracking aircraft. The magnitude of the impact will depend upon the location, number, size, and structural properties of the turbines. Wind… more
Abstract:Discovery of frozen volatiles at the lunar poles is transformative to space exploration. In-situ resources will provide fuel to support far-reaching exploration and enable commercial endeavors. While satellite data supports presence of polar ice, driving and drilling must confirm presence, determine… more
Abstract:Fixed wing UAVs such as the Predator, Global Hawk, and Shadow have become invaluable C4ISR and force projection assets. They have acted as force multiplers, have reduced risk to human personnel, and have enabled new tactics, techniques, and procedures (TTPs). Use of Vertical Takeoff and Landing… more
Abstract:ABSTRACT: Confronted by a vast quantity of data, presented piecemeal, sporadically and at varying levels of detail, the human analyst is often overwhelmed when trying to effectively monitor even medium-sized areas of interest. Offline, there is a wealth of data, resolution, and time to pick through… more
Abstract:ABSTRACT: The production of 3D models from aerial imagery has been an active research area for many years. Given sufficient image texture and a variety of divergent camera viewpoints, camera pose and scene structure are fully recoverable. Further, software for fully reconstructing a scene from an… 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.
