This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

PERIODIC RESPONSE TIME TESTING HAS BEEN PERFORMED FOR THE PAST TWELVE YEARS ON THE SAFETY SYSTEM PRESSURE SENSORS IN MANY NUCLEAR POWER PLANTS. HOWEVER, THE RESULTS OF THESE TESTS ARE NOT RELIABLE FOR ASSESSMENT OF AGING EFFECTS. THEIS BECAUSE INADEQUATE METHODS AND PROCEDURES HAVE BEEN USED IN PERFORMING THE MAJORITY OF THE TESTS. THIS PROPOSAL OFFFERS AN EXPERIMENTAL RESEARCH PROJECT TO PROVIDE ...

Currently, thermal spray (flame and plasma spray) is the only single step method of applying most metal and non-oxide ceramic coatings to large objects. These coatings are usually of a low quality, and thin films cannot be applied. An in situ deposition technique that inexpensively and easily applies nitrides, carbides and other non-oxide thin or thick films in an environmentally friendly manner i ...

Currently vacuum based methods of PVD and CVD are the only processes for forming GaN thin films and coatings. These methods are usually expensive and are not applied in a production friendly manner. An atmospheric deposition technique that inexpensively and easily applies GaN thin or thick films in an environmentally friendly manner is a priority for any number of DOD and commercial applications. ...

The primary goal of Phase I work is to demonstrate the feasibility of synthesizing gallium nitride (GaN) powder. Secondarily, this powder will be used to grow high-purity single crystals of GaN from a liquid GaN phase. This would be accomplished using a proprietary variation of the skull melting technique. Since GaN demonstrates peritectic-type decomposition at atmospheric pressure, the entire sku ...

This research project is directed at developing an operator perception model based on insight from empirical perception data combined with knowledge of how the human vision system processes information. As a first step in this direction, we are proposing to collect perceptual data and use this data to develop, implement, and evaluate concept approaches for augmenting human operator performance in ...

This proposal suggests that a basic data collection, management, and fusion framework is ideally suited for integrating distributed data from multiple heterogeneous sources and making it available on a multi-point basis for analysis, viewing, and C**4I applications. The basic framework proposed was built (and is currently under ongoing development) to support object-oriented, temporally consistent ...

This program will demonstrate key enabling technologies for Terabit/second optical fiber networks capable of meeting critical DoD needs. Optical network technology offers characteristics that satisfy many DoD requirements. These characteristics include improved data handling through multiwavelength transmission in single optical fibers; enhanced network security; greater inter-network operabilit ...

The proposed effort will apply advanced methods of hybrid learning to problems of detection and identification of sensory events (e.g., boost phase evens). Our approach aims at building a vision system capable of hybrid learning, in which symbolic (rule-based) and subsymbolic (neural network) strategies are integrated to achieve high efficiency and accuracy both in learning human comprehensible se ...
