This proposal comprises research efforts to study a dynamic non-stationary friction regime with a variable range of external factors or parameters. This research method considers the development of special non-linear mathematical models for enginetribology including the lubricating oil film thickness as a function of a series of independent parameters in extreme working conditions. These modelin ...

Early and effective hemodialysis can decrease mortality of trauma patients with acute renal failure. Unfortunately, current technology is not easily deployed in the field or during transport of patients. The Sorbent Hemodialysis (SHD) System now beingdeveloped using technology from Ash Medical utilizes the SORB cartridge to produce and regenerate a small dialysate volume (6 liters). The SHD improv ...

The development of a process to produce bulk silicon carbide (SiC) boules with alternate crystallographic orientations, specifically the a-orientation, which is perpendicular to the normally-grown c-orientation crystal, offers significant improvements inthe SiC semiconductor electronic properties. Specifically, the electron mobility will increase by a factor of five for 4H-SiC, and the thermal co ...

Absence of low defect density large diameter (~100 mm) silicon carbide (SiC) wafers is a major barrier for the commercial production of SiC-based devices. Hence, the development of a process to produce large diameter bulk SiC boules with low defectdensity offers a significant impetus for the widespread commercialization of SiC-based devices. An approach that will simultaneously increase wafer di ...

We propose to further develop a new technique for imaging underground facilities based on the passive monitoring of acoustic emissions from both stationary and moving equipment within such facilities. It is well known that all mechanical devices, such asmotors, gears, etc, emit acoustic signals. It is possible to identify an acoustic source based on its noise spectrum. During Phase I, we have demo ...

Development of a miniature mass spectrometer using a cylindrical ion trap mass analyzer will provide a portable instrument capable of detecting trace level components from gaseous samples.The miniature mass spectrometer developed here will be the only miniature instrument capable of multiple stages of mass analysis (MS/MS) thus coupling added selectivity to the very sensitive instrument.This instr ...

This Phase II proposal outlines a plan to develop an instructional package that supports embedded training using mixed reality technologies to train proficient operation and tactical use of Objective Force Warrior (OFW) soldier equipment. Thisinstructional package will include the following components: innovative training and assessment methods and tools to support embedded training; authoring too ...

This document proposes a system that allows engineers from multiple disciplines, using numerous simulation packages, to input data from a variety of sources, both run-time and off-line, in a manner that allows them to examine that data in a number ofdifferent ways. The architecture should allow for a great deal of flexibility and extensibility, allowing engineers to add multiple types and styles ...

Medium caliber cannons, such as the Army's M230 chain gun, currently utilize a high current electrical pulse to initiate the propellant. While electrical ignition is reliable, electrical based primers are susceptible to premature ignition from EMI, EMP, orother stray or directed electromagnetic sources. In the event of a weapon jam, electrically initiated primers are dangerous as the potential for ...
