In this proposal, we identify QoS metrics based on our insights on heavy-tailed phenomena in ad hoc wireless networks, determine the potential performance impact of heavy-tailedness on ad hoc routing, define routing policies based on such insights and metrics, and propose a QoS Routing protocol (HAQR) that captures the heavy-tailed nature and provides quality of service for multi-hop wireless ad h ...

Hydrogen embrittlement is a growing problem with new advanced high strength steels (AHSS). These newer alloys are more susceptible to cracking which usually occurs at ambient temperature and at lower hydrogen concentrations. Conventional methods to determine hydrogen content in a weld involve destructive testing of weld coupons. There is currently no field sensor capable of non-destructive meas ...

The objective of this STTR Phase I proposal is to develop new generation nanocrystalline materials which would be superior to surface modified activated carbon in terms of adsorption capacity and selectivity towards chemical agents and very importantly are expected to have unique capabilities of destructive adsorption. NanoScale Materials Inc. will utilize the nanocrystalline materials developed a ...

The proposed project is a virtual workbench, part-task simulator for training medical personnel to perform simple emergency neurosurgical procedures for trauma, specifically to (1) explore (open) depressed skull fractures and remove bony fragments, (2) drill a burr hole into the skull for either diagnostic (placement of intraventricular catheter or extradural intracranial pressure monitor) or ther ...

A new Aluminum gallium nitride (AlGaN) based heterojunction field-effect transistor (HFET) structure is proposed that utilizes avalanche impact ionization for very high frequency operation (>100 GHz). The main goal of this program is to demonstrate the potential of these devices as a replacement for vacuum tubes in mm-wave applications including radars and communications transmitters. In the Pha ...

This proposal suggests research on security issues for mobile databases running on a mobile ad hoc network (MANET). It will explore both state of the art commercial systems and advanced research issues for mobile security management. The first step will involve an extensive study of the commercial off-the-shelf technology. This study will identify the resources that can be used for addressing secu ...

One of the most significant challenges facing the Defense Industry today is the lack of interoperability between software applications. Weapons systems data is voluminous, complex, and distributed across many disparate applications. Typically, only a few of these applications are truly integrated and manual processes are required to synchronize data maintained across multiple systems. Users mus ...

The Phase I objective is to demonstrate dislocation reduction in both cadmium telluride (CdTe) and subsequent HgCdTe epitaxial layers grown on silicon substrate using an intermediate nanocrystalline CdTe buffer layer of optimized thickness and size. Nanocrystalline CdTe buffer layer will be deposited on silicon substrate by low cost processing method/s. The method consists of (a) Colloidal synthe ...

This proposal focuses on developing a protein manufacturing platform based on a novel vector system that can rapidly and efficiently generate cell lines capable of producing proteins at high yield and purity in a short time period. Lentigen is able to perform such a quick protein manufacturing process based on its LentiMaxT lentiviral (LV) gene delivery technology that stably delivers one or more ...

This Phase I STTR ARMY project proposes the development of advanced processes to mix solutions of low melting temperature sublimable solid eutectic materials with nano-sized metal flake powders and then solidify these slurries into a desired shape compact. The main project goals are to accomplish good metal flake powder deagglomeration in the liquid eutectic phase, to attain good densification aft ...
