The development of a two step materials growth process for the low cost production of AlGaAs / GaAs complementary HBT epiwafers is proposed. A new high stability source for carbon doping with CBr4 will be demonstrated and used to grow the p-type layers in both Npn and Pnp device structures that are monolithically integrated on the same semi-insulting substrate.

This project enables and incentivizes adaptation of IEEE Draft Standard 1076.1 (VHDL AMS) by mixed signal (analog/digital) engineers by providing a feasible, low risk migration path for existing SPICE like models (equivalence), then adds capability beyond that of SPICE (incentive). Specific work items include "black box" VHDL AMS source code generator technology, SPICEcompatible analog solver tech ...

The US Air Force plans to develop and demonstrate an aero-propulsion engine for hypersonic flight to Mach 8. This program focuses on use of hydrocarbon fuels and expendable engine designs for long-range cruise missile applications. A critical element for realization to the Air Force's hypersonic vehile mission is advancement in supersonic combustion ramjet engine technology. Development of conc ...

The overall objective of this work is to develop a general-purpose CFD-based, shape optimization tool for robust and efficient aerodynamic shape optimization. Shape optimization is a technology where design optimization algorithms are coupled with geometry/shape deformation tools and engineering analysis codes such as computational fluid dynamics and structural analysis. The optimization algorit ...

A data recording system will be designed that will be smaller than the recorders presently available and contain high speed nonvolatile memory to guard against data loss when power fails. Various nonvolatile memory technologies will be investigated including a new memory technology called MRAM (magnetoresistive random access memory) which has all the characteristics required including fast write ...

We propose the development of an improved crack and corrosion detection system for hidden defects in multilayered metal structures typical of aircraft. Remote field eddy current (RFEC) techniques will be combined with an array of sensitive, broadband, giant magnetoresistance (GMR) sensors to detect damage deep within the structures. The system offers improved detection without the limitations of ...

The challenge of reliable, high speed data transfer between subsystems on spacecraft can be more easily met when subsystems are elctrically isolated. This program will show the feasibility of a high speed, low power isolated digital transceiver device based on spin valve magnetoresistive isolation technology. Commercially available isolated transceiver modules require upwards of sixty discrete c ...

As pulsed power devices mature a requirement emerges for the efficient coupling of the power source of remote locations. For certain applications this coupling can take the form of existing high power switch/conditioning technology coupled with a suitable transmission line. For mobile, remote or harsh environments standard connection techniques are too bulky and require too much set-up time to b ...

The objective of this research effort is to design a mobile robotic platform, and the related operator interfaces required for remote operation, which enhance a soldier's abilities to accomplish mission goals. This system will be modular in design, scaleable, low cost and rugged. The size and weight of these platforms will range form a meter long and 200 pounds, to a few centimeters long and abo ...

Superior information over one's adversary allows control of the battlespace, and ultimately provides opportunities to tales advantage of me adversary's vulnerability. C4I planning is critical to shape and control the pace and phasing of battlespace engagements, and requires direct access to battlespace information in order to utilize it effectively. Effective C4I planning requires the ability to ...
