GaInSb/InAs superlattices show great promise as materials for use in very long wavelength infrared (VLWIR) detectors. This III-V compound offers advantages over current HgCdTe technology in both anticipated performance level and ancillary support system(e.g. cryogenic cooling) costs. Due to its piezoelectric characteristic, (111)-oriented superlattice lowers the effective bandgap energy when com ...

While recent advances in high speed machining (HSM) of aluminum materials have successfully achieved significant reductions in cost of aerospace structures, these advances have not been successfully applied to titanium material components. Machining costsare a major cost driver in these components, so a meaningful increase in metal removal rate capability will have a significant economic benefit. ...

The recognized risks associated with the introduction of new material and oil formulations for propulsion system bearings and gears have created a crisis with respect to urgent needs for increased load, speed and temperature. Conventional test methods formaterials and oils have insufficient linkage to service performance and mechanisms that control life and durability. The recognition of the cur ...

This proposal suggests an approach to providing self-organizing network communications between the nodes comprising a nanosatellite constellation. Using the proposing firm's existing body of work on self-organizing ad hoc networks for 802.11 wireless LANsand miniaturized robotics platforms as a baseline, issues relating to ad hoc networking in a nanosatellite constellations will be identified, a ...

The Air Force needs to access a large variety of databases with varying data schemas and storage architectures from an equally large variety of applications. This presents a rewarding but challenging problem of enabling access to these databases via commondata access models and services. This problem, and also its most challenging implementation aspect, is particularly significant in the context o ...
