Historical methods of reliability assessment are less and less effective as device sizes shrink. Larger sample sizes and longer duration tests are increasingly needed. At the same time, efforts to continue scaling semiconductors to ever smaller geometries is leading to an explosion of new device structures, materials and processes. The cost of testing these innovations is becoming a major barrier ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: Our Phase II program concentrates on extending, rectifying, and validating the ETM engineering transition model for 3D flows. ETM solves PDE"s for both transition onset and intermittency and has full 3D capabilities, shown to generate swept onset curves and variable transitional lengths downstream of the onset curve. It is incorporated into Navier-Stokes codes in a manner akin to the i ...

Military personnel frequently suffer blast and/or blunt head injuries. A number of recent studies have indicated the presence of vestibular deficits in the acute period following mTBI accounting for up to 90% of all injuries. Dizziness is the most commo

ABSTRACT: Primordial, Panoptic, and intuVision propose the development of Tentaclea multi-camera immersive surveillance system that synthesizes information from hundreds of video streams into an intuitive 3D representation. Team Primordial will start with our existing state-of-the-art baseline componentsPanoptic C-Thru, intuVision Panoptes, and intuVision Video Recallwhich already fully meet 6 a ...

ABSTRACT: The new single-stage high step-down ratio/high power handling/high current capable solid-state power DC/DC converters will substantially increase the power density of radiation-resistant DC/DC converters. This new converter has the potential to boast power densities 3 5 times current state-of-the-art, while reaching radiation hardness unobtainable by conventional magnetic based solutio ...

ABSTRACT: Electronic boxes need to be quickly and easily attached and removed from the satellite payload deck in a spacecraft structure. Hampering the removal process is the vulcanized (RTV) used as the Thermal Interface Material, TIM. Because of its strong bond, it makes removal of the boxes time-consuming, and difficult to rework. Compounding the problem is the fact that electronics continue t ...

ABSTRACT: Data rates necessary to support the warfighter continue to increase. New satellite interconnects are needed which have minimal signal distribution weight and power overhead. Optical backplanes which accommodate these new"short haul"payload processing and"long haul"signal distribution across bus and payload subsystems are often fixed, dedicated interconnects with little to no flexibili ...

Three tiered Thermal Bus System isothermalizes the satellite, allowing payload components to be mated in arbitrary locations without requiring detailed thermal analysis. The first tier is pyrolytic graphite embedded in aluminum panels (kCore) to provide local spreading. The second tier consists of embedded heat pipes to isothermalize each panel. These heat pipes also interface with third tier whic ...

ABSTRACT: Space-based wide field of view cameras can be enabled to point near or directly at the sun if the sunlight is prevented from reaching any lens surfaces. A pixellated glare shield placed in front of the first lens surface that darkens in a region sufficient to shade the lens will accomplish the task. Two laminated passive matrix liquid crystal displays will achieve contrast ratios of o ...
