Metallic additive manufacturing (AM) is an attractive technology for the production of lethality test articles due to the potential for significantly reduced lead time and manufacturing cost.However, in order to be effective in providing accurate lethality data, the properties of the AM material have to match closely the properties of conventionally manufactured alloys found in real threat targets ...

The expected life of satellite Li-Ion batteries is determined by many factors, including thermal considerations, electrode chemistries, orbit and mission life, DOD, and pulse power requirements. First-principles battery model literature pertains primarily to orbital cycling at moderate DOD under isothermal conditions without variable power loads. Knowledge must be extended to encompass wider life ...

Phase I objective is to demonstrate the feasibility of our proposed passivation approach to minimize the dark current noise and improve the quantum efficiency in the GaSb based type II superlattice detectors. Phase I goal is to demonstrate the feasibility of our technology to fabricate photodiodes with cut-off wavelength in excess of 10µm, quantum efficiency exceeding 70% and dark current density ...

Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

Our proposed second order uncertainty (SOU) product is a decision making software solution that addresses the problem of providing accurate and precisely defined decision courses of action (COAs) of complex, time-constrained problems in a fraction of the time required by alternative methods striving to achieve the same level of precision. Complex decision situations can deal with large volume of ...

The Missile Defense Agency (MDA) seeks technical investigations related to the development and application of advanced electronic materials, processes, and devices to meet its need for radiation hardened, high performance electronics for critical space and missile applications. With the advent of smaller transistor dimensions and reductions in price per bit, significant changes in materials and pr ...

Providing Army combat medics with meaningful experience in treatment of battlefield injuries is a particular challenge. Moulage has the potential to assist in acquiring what could otherwise be very hard-to-come-by preparatory experience for distressing real-life emergencies medics and soldiers may encounter in the field. However, current approaches to moulage are limited in their ability to reflec ...

EO/IR elements of the Ballistic Missile Defense System (BMDS) responsible for detecting and tracking ballistic missile threats encounter extraordinarily challenging threat and scene phenomenology. Specifically, non-stationary clutter characteristic of airborne and satellite-based sensor systems, along with dim target signatures, closely-spaced objects, and dense debris clouds typical of ballistic ...

The ISSAC Team propose a novel method to encapsulate legacy models and simulations that allows these components to take advantage of modern, multi-core, multi-processor hardware suites. Encapsulating these legacy codes provides 3 primary advantages to deal with complex systems and systems of systems (Air Force, Navy, Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA) ...

This Phase I STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa m1/2) ultra high temperature Ta-Hf-C-based composites (UHTC) with an outstanding oxidation resistance for use as thermal protection systems for hypersonic applications, as well as for advanced rocket nozzle throat components. UES will apply a novel "Top Down" approach to control the micro ...
