ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: Methodology for prediction of soot build-up in liquid film-cooled rocket engines will be incorporated into the CRUNCH CFD code, using a reduced-mechanism pyrolysis model and soot formation model developed at University of Virginia. A companion experimental program will be conducted at University of Virginia to collect data for calibration of the pyrolysis models for conditions and fuels ...

ABSTRACT: The proposed program is a joint effort between General Sciences, Inc. (GSI) and Drexel University. The proposed concept for Plasma Generation is based on the use of highly exothermic condensed phase reactions yielding temperatures considerably higher than the boiling points of candidate metal elements with residual energy to maximize their vapor yield and, with high probability to enter ...

ABSTRACT: Present CALPHAD software tools do not address data heterogeneity and fragmentation challenges in a way conducive to the feasible development and maintenance of high-quality databases of more than, perhaps, 5 or 6 components, yet alloy systems of commercial interest can easily reach 12-15 components. We propose to use a newly developed thermodynamic software engine and new algorithms to d ...

ABSTRACT: This Phase I effort will identify and evaluate candidate materials to replace existing beryllium-copper alloy components for use in aerospace ground test flow facilities. The candidate materials must offer similar or better performance metrics (dimensional stability, lifetime, etc.), be domestically and readily available, offer similar or cheaper costs, and the ability to withstand temp ...

The main goal of Phase II is to validate the Phase I prototype and develop an integrated design and analysis tool for assessing large damage and blends for compressor IBRs on gas turbine engines and other blade systems. This tool will have at its core the automated analytical modeling of as-measured or as-expected airfoil blends for the structural and aero response to the shape change due to blend ...

ABSTRACT: The proliferation of autonomous- and human-machine systems necessitates the creation of new tools for system design and evaluation. Key among these are simulation testbeds that support interactions between multiple warfighters and systems, and methods for creating and integrating intelligent agent models into simulation environments. We see a significant opportunity to advance the state ...

Objectives and Intellectual Merit: The infrastructure of modern civilization is a set of complex systems1 that dynamically interact across multiple layers of abstraction. Researchers from many disciplines2 are designing analytical tools for predicting the global and local behaviors of these complicated, multi-layer networks. Easily usable, available (open source) and inter-operated tools are neede ...

The development of a high fidelity, generalized computational framework with the necessary physical submodels incorporated for the analysis of multiphase, combusting, internal and external ballistic flows is proposed. The focus in Phase I will be developing a framework based on an existing unstructured multi-element, fully implicit, CFD code to provide an end-to-end analysis capability for interna ...

Applied Colloids proposes the use of its proprietary nanofluid technology as an add-in treatment process for gearboxes and transmissions of military ground vehicles that would reduce the internal friction generated in them. This would reduce the vehicle fuel consumption by 2 to 3%. It would also reduce the wear and maintainance costs for this equipment. Applied Colloids will form the nanofluids ...
