Reduced mass materials are critical to the success of aerospace systems. Thus, large air and space structures can benefit from lightweight composite materials. However, their adoption is impaired by the lack of a robust, cost-effective fabrication process, principally because the autoclaves used to consolidate composite laminates are so expensive for large parts. This program develops for US aeros ...

This program exceeded all key milestones. Using cellulose Waste, CMS demonstrated novel ethanol drying membranes via small scale dephlegmation process that yields fuel grade ethanol (FGE) at a lower cost than large switch grass ethanol plants. This success yields positive value for cellulose waste. We achieved targeted EPA goals of developing low cost environmentally friendly systems to enhance re ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

NASA's next generation of x-ray observation missions require x-ray calorimeters with superior energy resolution. Semimetallic HgTe has already proven itself as an excellent soft x-ray absorber material due to its low heat capacity. Hg0.834Cd0.166Te was shown in Phase 1 to have a heat capacity superior to that of HgTe. Hence Hg0.834Cd0.166Te-based microcalorimeter arrays are expected to have an ene ...

The objective of this proposal is to study and demonstrate novel GaAsNP/GaP/AlGaP technology for use in extreme photovoltaic (PV) energy conversion. NASA and the scientific community are interested in solar missions that go as far as Saturn or even into near sun conditions. Such missions present a challenging problem for PV technology. In addition to the requisite high efficiency and reduced so ...

The goal of this Phase II project is to deliver an integrated L-band transmit/receive (T/R) module which will be fabricated from a GaAs-based combined HBT/PHEMT epistructure. The T/R module will consist of a power amplifier, a low noise amplifier, and two switches. The performance goal for the low noise amplifier is 30 dB gain with a less than 1.0 dB noise figure. The performance goal for the p ...

The Complex Event Recognition Architecture (CERA) provides five major innovations: (1) The ComplexEvent Description Language (CEDL): a declarative language for describing complex events: that is, eventsthat can occur across time, be sensed from multiple channels, and be composed of the conjunction, disjunctionor negation of other complex or simple events; (2) The Complex Event Recognition Language ...
