5-D Systems and the University of Texas San Antonio (UTSA) Autonomous Control Engineering (ACE) Laboratory will prototype a system concept and produce a long term development plan for a tool to intelligently assist MDA M & S Systems Engineers in understanding the needs of their stakeholders. Our prototype will address the elicitation, capture, characterization, and refinement of a stakeholder fun ...

The process of an MDA stakeholder specifying a needed modeling and simulation system has many problems: they may be ambiguous, overly specific, overly general, contradictory, etc. Symbolic knowledge-based representation and reasoning systems have matured to the point where they can ameliorate this. E.g., an extension of Cyc can help a Marines ISR-E requirements officer prepare a JCIDS CDD needs ...

System requirements elicitation is a time consuming process with an extremely high penalty for errors. Mistakes made in the requirements phase will cost 50 times more to fix while they are uncovered in the production phase as compared to fixing them in the requirements phase. VIStology and Northeastern University are proposing to develop an approach for supporting the requirements elicitation phas ...

The overall objective of this program is to improve the producibility of HVPE GaN through the use of in-situ monitoring during the growth process. Various in-situ monitoring devices will be used: a UV absorption technique to monitor the GaCl concentration above the growing GaN wafer; a commercial BandiT system capable of measuring optical emission from the growing wafer in order to measure the su ...

Global Technology Connection, Inc., in collaboration with their academic partners and industrial partners propose to develop a prototype integrated physics-based model and accelerated testing process that will reduce the qualification time and testing required for Li-ion cells used in LEO/MEO satellite applications. The integrated physics-based model will focus on three key Li-ion cell degradatio ...

Global Technology Connection, Inc., in collaboration with academic partners, Georgia Tech"s Center for Innovative Battery and Fuel Cell Technologies, Penn State University, and industrial partner Eagle Picher propose to create a physics-based modeling for predicting the life performance of Low and Middle Earth Orbit (LEO/MEO) Lithium-ion cells. The relationships between solid-electrolyte interpha ...

An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

Cermet, in collaboration with researchers at Georgia Institute of Technology, proposes to implement a lattice matched III-Nitride technology using existing substrates. The implementation of a lattice matched substrate promises to produce near dislocationfree III-Nitrides for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the devel ...

The objective of this proposal is to demonstrate the feasibility of growing centimeter-size aluminum nitride (AlN) crystals by subliming polycrystalline AlN in nitrogen atmosphere, and to demonstrate single crystalline quality meeting or exceeding thestandards of commercially available SiC wafers. The growth process, which utilizes high temperature, subatmospheric pressure and a steep temperature ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...
