Diamondlike multinetwork and network-crystalline atomic-scale composite coatings constitute a new class of materials with unique properties including high adhesion to virtually any substrate (including materials, crystalline and glass dielectrics, plastics), excellant thermal and diffusion barrier properties, good hardness, high elasticity and flexibility, very high thermal shock resistance, extre ...

This proposal describes a basic research effort to establish the feasibility of a cost-effective, modular, high-fidelity, reconfigurable, realtime simulator of radar warning receivers. An open architecture, multi-processor design for the simulator is proposed which will allow individual EW processing functions to be evaluated in the context of full EW system operations in dense, realtime mission s ...

We propose the exploration of single crystal GaN waveguides for the fabrication of optoelectronic integrated circuits. The feasibility of using GaN for short wavelength (up to 365 nm) OEIC's will be established in Phase I via the demonstration of a channel waveguide based phase shifter. The Al(sub x)GA(sub 1-x)N material system with its transparency from 365 nm to 12 microns, tunable refractive in ...

The goal of this project is to create tools to support the formal verification of VHDL designs. Two existing formal verification tools will be enhanced to support VHDL. The first, Spectool, will allow a class of designs, the synchronous finite-state controlled systems, to be specified and verified and then translated into VHDL. This capability will allow VHDL to be used as an interface between Spe ...

The Air Force currently lacks a facililty to perform rapid turn-around parametric evaluation of low-speed, high angle-of-attack configuration development, modifications and flow field investigations. With the current trends in aircraft design and execution driving maneuvering requirements for military aircraft to progressively higher angles of attack the need for such a facility is becoming paramo ...

The utilization of large amplitude nonlinear motion simulation in the development and analysis of military aircraft configuration flying qualities and flight controls, flight test data analysis, as well as flight test planning and training has advanced concurrently with the advances in computational capabilities and airframe modelling. Unfortunately, user's access to these high level simulations h ...

Medical treatment for U.S. Air Force personnel suffering from high altitude sickness and edema currently entails aeromedical evacuation flights (AEF) to transport the stricken individual(s) to an Air Force Base which possesses a stationary hyperbaric chamber. Unfortunately, AEF's are not only expensive, they place an already non-combat ready solider at a much higher risk of condition deterioration ...

Linguistically-based text generation techniques will be used to automate the generation of software documentation from CASE tools. Two types of software documentation are typically produced: (l) formal documentation describing the structure, interfaces, data types and other mathematical properties of software, and (2) semantic documentation describing the meaning and purpose of software components ...

The current development of an electric power generation system for the More Electric Aircraft (MEA) is based on a low-risk extension of existing three-phase, switched reluctance machine (SRM) technology. This research program proposes to study an alternate two-phase SRM and its associated power-conditioning converter. By the nature of the proposed machine, it has 50% of its stator coils active at ...

In situ Thermal Accelerated Vacuum Extraction and Bioremediation processes are proposed for feasibility study. Both Vacuum Extraction and Bioremediation are acceptable means for in situ soil decontamination; however, both have practical limits related to soil temperature. Vacuum Extraction is limited to semi-volatiles, a vapor pressure/molecular weight criteria, while bioremediation is vastly affe ...
