Abstract:Fiber reinforce polymer (FRP) composite materials are seeing increasing use in the construction of a wide variety of aerospace structures. However, uncertainties regarding the material's impact durability continue to plague the FRP composites community. To address this need, ADA Technologies,… more
Abstract:NASA space exploration vehicles are trending to higher pulse power, energy capacity levels and cycle life in order to meet exponentially increasing performance and lifespan requirements. As the demand for on-board power and total energy-storage capacity has continued to increase, there has been an… more
Abstract:ABSTRACT: Mycotoxins are lipophilic agents derived from fungus that pose a significant public health problem around the world. The effects of mycotoxins include loss of human and animal life, increased healthcare and veterinary costs, reduced livestock production, and disposal of contaminated foods… more
Abstract:ABSTRACT: Energy harvesting has emerged as a critical need for many current and future Air Force missions to enable their long lifetime requirements. Traditional approaches have focused on harvesting solar and vibration (i.e., via the use of piezoelectric materials) energy. More recently,… more
Abstract:The Navy and the U.S. Military as a whole will be challenged to find innovative solutions to ever-rising peak power demands stemming from the introduction of electricity-driven vessels and new directed energy weapons in the coming decade. Circuit protection from voltage variation is also a concern… more
Abstract:ABSTRACT: Fires in dry bays and engine nacelles of military aircraft present a significant hazard to aircraft survivability. The USAF is interested in reducing weight and improving performance of systems to protect these spaces. ADA Technologies, Inc. has 10 years experience developing advanced… more
Abstract:Naval aircraft and the Joint Strike Fighter in particular face the challenge of adding functionality while avoiding weight increases that could hinder performance. Additionally, electrical power-hungry features such as electro-hydrostatic actuators for flight control surfaces and the possibility of… more
Abstract:We propose to develop a self-contained, integrated, disposable universal sampling platform that enables streamlined workflow in the preparation of viral and bacterial sample and obtaining PCR-ready nucleic acids and immuno-reactive content from a variety of sample matrices such as water, whole blood… more
Abstract:The U.S. Army is the owner and operator of the world"s largest fleet of ground vehicles. Despite substantial interest in hybrid electric vehicle (HEV) technologies, there are no tactical HEVs in the military today. One limitation is that most commercially available ultracapacitor systems have… more
Abstract:Micro Air Vehicles (MAV) have emerged as a critical need for the U.S. Air Force. MAVs are envisioned to conduct a variety of indoor and outdoor reconnaissance missions and must be highly mobile and man-portable. Furthermore, many of the envisioned missions for MAVs require significant endurance.… more
Abstract:ABSTRACT: Micro Air Vehicles (MAVs) are emerging as a critical technology for the U.S. Air Force with increased endurance identified as an essential need to enable MAVs to execute meaningful missions. Unfortunately, current state-of-the-art lithium-ion batteries, the preferred energy storage… 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.
