Abstract:Monolithic Microwave Integrated Circuits realized on GaAs, GaN, InP, SiGe, and to a lesser extent Si are integral components of many deployed NAVY detect, control, and engagement systems due to their broad bandwidth, fast-response time, and small size (10 W).
Abstract:…, but will be less costly because they can be batch fabricated on silicon wafers. In Phase I, MTI focused on achieving a thorough understanding of overall requirements and trade-offs for an"eye-safe"1535nm Er:glass laser which must provide on-demand pulse firing.… more
Abstract:… m. This either limits the resolvable energy resolution and/or requires long complex spectrometers to achieve the desired resolution. Sydor Instruments, in collaboration with Lawrence Berkeley National Laboratory (LBNL) will demonstrate the feasibility of a novel direct-… more
Abstract:Often illegal border crossing along the southern border takes place in unimproved areas not constantly monitored by Border Patrol agents or deployed sensors. Agents must rely on sign-cutting to detect traffic and start their pursuit. These signs can be difficult or impossible to… more
Abstract:ABSTRACT: We propose a concept for the detection of radiological sources at stand-off distances, using a two part system consisting of a detector tag and a radar system. A radiation-sensitive resonant circuit with nonlinear properties (the tag) is placed near a kn BENEFITS:… more
Abstract:Acellent Technologies is developing a system for the US Navy that incorporates innovative ways to detect and track corrosion, measure clamping force and bolt preload in bolted joints typical of aircraft structures. Many of the corrosion inspection methods currently employed in… more
Abstract:Current Structural Health Monitoring (SHM) systems can be used for composite damage monitoring. However, current systems lack the ability to accurately detect, locate and characterize damage for complex composite structures with local property variation. Acellent Technologies… more
Abstract:ABSTRACT: Fires initiating in engine nacelles and dry bays are the most common causes of loss of aircraft. However, since the Montreal Protocol restricting the production of Halons, a replacement has not yet been accepted by the aircraft survivability community despite numerous… more

Abstract:NAVAIR PMAs are motivated by substantial maintenance cost savings to switch aircraft paints from matte to glossy. Yet NAVAIR must confidently weigh these major cost savings against possibly serious survivability penalties from sun glints. To definitively answer these survivability trades, we propose… 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.
