Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

Acroamatics, Inc. proposed to perform research to develop a method permitting the telemetric transmission of avionics bus data from an air vehicle under test to a remote receiving station using a narrower radio frequency (rf) bandwidth than presently required. Increasing use of digital avionics in aircraft and reduced availability of rf spectrum make this an important topic of development. The s ...

The recent DNA-sponsored conference on ¿Verification and Validation of Nonlinear Structural Dynamic Codes,¿ September 1993, highlighted the need for reliable models as well as codes. At the present time there are no generally available software tools for utilizing experimental data to correct and refine models implemented on general-purpose codes such as DYNA3D. Nor are there tools available f ...

An innovative Microwave-Powered Monopropellant Hydrogen Plasma Ignition System for hydrogen fueled rocket engines, which develops a plasma using only the hydrogen feed gas to the igniter, is proposed to replace current enhanced spark or torch igniters which require the use of a pre-mixed quantity of hydrogen and oxidizer. The ignition system employs air plasma generation technology developed for ...

Advanced aircraft are required to perform large amplitude maneuvers and high precision tracking in the presence of disturbances, uncertainties, nonlinearities, and component faults. The recently emerging nonlinear H control approach is proposed here to meet the ever stringent mission requirements on advanced aircraft. Our approach features the following innovations: 1) by incorporatin ...

Theoretical chemistry techniques used to provide fundamental understanding of the molecular requirements for achieving conductive and nonlinear optical properties in polymeric materials are implemented in large scale parallel software enabling investigations on realistic models. The algorithms are based on techniques for simultaneous optimization of the electronic and nuclear coordinates. Linear r ...

Apollo Enterprise proposes to develop a highly sensitive, remotely deployable sensor system for hydrocarbon detection in waste water. The novel device is designed to monitor the hydrocarbons in waste water in real time and will serve as a tool to minimize the release of contaminated water into local waste-water systems. Current monitoring is performed by visual inspection based on the presence of ...
