Explosion bonding of dissimilar materials has been performed since the 1960s on a commercial basis. However, titanium and ultra high hardness steel is not currently fabricated. This research will develop baseline explosion bonding parameters for titanium and medium carbon alloy steel in the annealed condition and susequent parameters for heat treating the steel to the desired hardness. This wor ...

The topic presented in this proposal has direct application to the development of non-lethal devices capable of temporarily incapacitating personnel, controlling crowds, immobilizing small vehicles, and other applications where a controlled amount of acoustic c energy needs to be delivered a a distance. The proposed effort would determine the characteristic acoustic waveforms and amplitudes gener ...

The increasing number of missile launches and aircraft operation near missile test ranges has led to an increased hazard to the aircraft from wayward debris. The proposed study will systematically review and assemble the relevant data and applicable laws of physics into a computer program that will evaluate the actual risk for both mid-air collision between an aircraft and missile debris, and the ...

Future combat armored vehicles, air-defense artillery, and attack heliopters are required to perform precise pointing in the presence of unpredictable terrain motions, unmodeled flexible dynamics, unmeasurable disturbances, and nonlinear/time-varying effects. To meet this challenge, a control scheme integrating nonlinear control, linear robust control and disturbance estimation/compensation will b ...

This project proposes the high precision intelligent sensor based robotic control system to enhance the performance accuracy of a robotics system. The proposed design concept: (1) optimally combines several classes of sensors (e.g. touch, force, proximity, etc.) to improve the path planning and trajectory evaluation (i.e., controlled trajectory enhancement); and (2) innovatively employs multi-lev ...

Fiber optic communication networks utilizing wavelength division multiplexing (WDM) have been shown to be the most promising for realizing enormous bandwidth (terabit) for information transport and processing. A key device in the wideband WDM netowrk is a wavelength selective crossconnect for efficient routing of optical signals. Among the various approaches, the acousto-optic tunable filter (AO ...

The central focus of the work proposed herein is the application of neural network estimation and classification methodologies to emergency medical care. On the pre-hospital scene, first-aid workers must, often in a matter of seconds with spare information at hand, make critical decisions concerning the yrgency of an injured patient's condition and the type of trauma care required. This decisiona ...

The conceptual and preliminary design of an electron beam source for an affordable, field deployable Electron Beam Dry Scrubbing (EBDS) system is proposed. In the EBDS systems of interest, a pulsed electron beam system with average power of up to 50 kW and electron energy up to 600 keV is needed. cost, size, weight, and effectiveness set the principal engineering constraints. These translate in ...

Fundamentally, increasing engine power density, without an associated increase of engine speed, requires increasing the brake mean effective pressure (BMEP) as high as practical. Achieving the highest possible peak cylinder pressure, compatible with engine structural capability and desired life in order to obtain high power and goo fuel economy, requires innovative approaches in fuel injection sy ...

The primary objective of the Phase I research is to determine the feasibility of fast and non-obtrusive methods for representing situation knowledge in a naturalistic battlefield environments. A second key goal is to ground the selected methods firmly in cognitive research on knowledge representation and knowledge elicitation. To achieve these goals, we propose four tasks: (1) cognitive analysis ...
