The objective of this proposal is to further explore PbSnSe detector array on Si substrate. Two approaches are proposed. One is a zero-risk incremental advance that employs a new growth condition to reduce the dislocation density. Another approach is a novel fabrication technique with high-risk but it could enable revolutionary rather than evolutionary advances. IV-VI semiconductors such as Pb1-x ...

This effort proposes to design and demonstrate the concept of an innovative, Advanced BMDS Multisensor Fused Track and Discrimination Architecture that will enhance the generation of a Single Integrated Picture of the Battlespace. This Architecture permits enhancement of sensor-to-sensor track correlation handover of objects while characterizing their lethality for later target designation purpos ...

ABSTRACT: Missile defense radars use wideband waveforms along with coherent processing to extract detailed target features and perform high range /Doppler resolution functions. Reduced RCS targets embedded in high clutter (chaff, or chaff-like fuel debris, etc.) environments present significant challenges. Closely spaced objects and decoys accompanying targets of interest inherently increase the c ...

Successful advanced Naval ship design must be based on integrating multiple cross-functional systems. Future Naval systems will require innovation and a systematic integration in order to achieve increasingly demanding mission profiles in a cost effective manner. Since a large amount of the design cost (up to 80%) is locked during the conceptual phase, it is important to include both the traditi ...

Oxygen and/or air plasmas are widely used in different processes such as etching, purifying, ashing, surface cleaning, ozone generation and for electrical oxygen/iodine laser discharges. The oxygen plasma is an important example of electronegative plasmas and has been widely studied and modeled, including non-local effects due to discharge boundaries, low pressure or unsteady-state or afterglow op ...

The objective of this effort is to apply a systems-biology-centered methodology for the identification of subcellular mechanisms of mefloquine neurotoxicity, with the goal of developing a genetic profile to identify individuals predisposed to mefloquine neurotoxicity. The core hypothesis is that elucidating subcellular mechanisms of mefloquine neurotoxicity requires the combination of cellular lev ...

Although numerical analysis applications have proven to be effective and reasonably accurate, the effort required to develop the associated analysis models remains a challenging and time consuming task. While many meshing tools are currently available, decomposing and manipulating the design geometry and enhancing the topology for mesh construction are manual processes and place the heaviest dema ...

During the Phase I effort, we propose to evaluate the feasibility of performing ultrafast-laser-based ballistic imaging for studying liquid hydrocarbon and oxygen injection characteristics for possible application in bi-propellant rocket engines. Ballistic imaging has the potential to circumvent the difficulties associated with propagating light through dense media. Through the combined use of ult ...

Space applications continue to be limited by the availability of cost-effective power. Significantly higher efficiency cells with lower mass and volume are required to improve performance and lower mission costs; however, improvements in conventional multijunction technology are not expected to meet the necessary performance increases. Instead, new materials and mechanisms are needed to obtain th ...

Digital Fusion and The University of Alabama in Huntsville propose to develop a light filament based sensor system suitable for incorporation in an unmanned-aerial-system (UAS). This sensor system is intended to be useful, e.g., for sensing explosive residue or biotoxins at up to kilometer class distances. It has been demonstrated that white light filaments, which can propagate through the atmosph ...
