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 United States Air Force and the Department of Defense are investigating synthesis, scale-up and production of novel energetic materials including high energy density compounds and fuels. Five-membered heterocyclic rings containing nitro groups have demonstrated great potential as energetic materials. Synthetic and engineering challenges are impeding scientists from safely producing ...

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 ...

A software tool for residual strength and life prediction of advanced hybrid structures will be developed by enhancing and integrating an existing mesh independent 3D X-FEM solid element with a partially bonded cohesive interface element in Abaqus. The tool will be able to model arbitrary location, size of damage, and geometric configuration of fiber metal laminates with the coexistence of metal l ...

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: In order to avoid potential collisions with space debris future spacecraft in geosynchronous (GEO) orbit may be required to detect all objects in their local environment and will be required to have 4pi steradian coverage. Unfortunately the sun can blind and/or damage these sensors if precautions are not built into the sensor. APS is proposing to use an ultra-narrowband filter (0.001 ...

Carbon nanotubes form conductive composites at such low loading ratios and thus could be a key component in EMI shielding and conductors for lightweight aircraft wiring. Compared to conventional metal-based materials, electrically conducting polymer composites has attracted interest due to their light weight, resistance to corrosion, flexibility, and processing advantages. Minnesota Defense propos ...

ABSTRACT: In an attempt to develop novel oxidizer materials that the DoD requires for use in missile systems to meet performance and sensitivity requirements, NALAS proposes to screen potential candidates for suitability using first known and predicted information. Specific types of materials under consideration will be those possessing intra/intermolecular hydrogen bonds such as those appearing ...

ABSTRACT: At present, the common practice in the fighter aircraft industry is to use touch probes as secondary measurement systems to maintain tight machining tolerance control. The current touch-probe inspection process renders the typical milling machine idle while features of the machined part are slowly and intrusively being inspected, one feature at a time, over 1.5 to 3 hours per part. To m ...

ABSTRACT: Aircraft structural components are prone to damage typically assessed by various NDE tools. Damage to the aircraft structural components decreases operational readiness and compromises safety if improperly maintained; however, frequent inspections and maintenance is expensive. CBM+ equipped platforms, when supported by models and simulations typically experience an increase in operatio ...
