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 ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

American health care is in the midst of momentous change. Quality improvement principles are being used increasingly to enhance productivity and efficiency of health care delivery and to help contain costs. In producing patient outcomes and resource utilization measures, it is vital to control appropriately for case mix (i.e., differences in patients due, e.g., to illness severity) in the predicti ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

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 ...

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 ...

Novel ionic self-assembled monolayer (ISAM) processes for the fabrication of advanced electronic materials and devices will be developed through this program. Revolutionary ISAM methods to create nanostructured multi-layer inorganic/organic thin-films offer major advantages over conventional manufacturing processes, since the process is simple, low-cost and environmentally friendly in that no vola ...

F&S and Virginia Tech will cooperatively develop high performance protective ionic self-assembled monolayer (ISAM) organic/inorganic coatings for space-based optical and structural components, and work with Litton to upscale practical coating manufacturing. Revolutionary ISAM methods of creating multi-layer protective nanopartwcle films offer major advantages over con-ventional coating processes, ...
