ABSTRACT: In phase I of this program, we proposed to develop and validate detailed designs for highly scaled silicon photonic-electronic chips for applications relevant to the DOD in high-bandwidth data communication. This effort has been closely coordinated with the OPSIS (Optoelectronic Systems Integration in Silicon) project being led at the University of Washington, an effort to create an ope ...

The focus of this project is on large-eddy simulation (LES) of high-speed turbulent reacting flows. The Enabling Energy Systems (EES) Inc. has assembled a well-experienced team of experts to tackle all the main issues involved in modeling of such complex flows. Several innovative ideas have been proposed and team members have complementary expertise. The ultimate goal of the project is to develop ...

ABSTRACT: The objective of the Phase II effort is to extend the mathematical model investigated in the Phase I to include wind speed as well as temperature modeling, continue its development for a University of Notre Dame Wind Tunnel Facility, and demonstrate utility by adopting the model to a government facility specified by AFOSR. Specifically, the Phase II will include developmental work in ma ...

Ultra-high-performance concrete (UHPC) offers superior properties for structural applications. Existing UHPC design and production methods employ special materials and mixers. This project is developing mix design and fabrication methods for reliable production of UHPC with local materials and facilities. The Phase I project devised material selection criteria, proportioning methods and mixing pro ...

ABSTRACT: We will design, fabricate and test a quantum processing unit (QPU) based on a symmetric ion trap chip. The trap will provide trapping depth similar to that obtain with macrosize Paul traps. In addition to the ion trap, this chip will incorporate integrated optical systems which will deliver the light fields required by the elementary quantum processing unit (or quantum sensing unit). ...

ABSTRACT: This Phase II proposal seeks to develop a prototype speech segregation system that can significantly improve intelligibility of noisy speech for human listeners, a technical challenge that has eluded a solution for decades. Motivated by principles of auditory perception, system development is based on an auditory scene analysis approach to speech segregation. This approach differs subst ...

ABSTRACT: MO-SCI Corporation and Missouri University of Science and Technology have developed and evaluated fusion welding technology applicable to ultra-high temperature ceramic (UHTC) composite joining during a Phase I ceramic joining program. This Phase II program will improve arc and reactive plasma arc welding techniques and consumables to improve joint quality. Work in the Phase I resulted ...

ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts for the interaction between out-of-plane failure and ...

The Air Force has an interest in a run-time mission pilots assistant that will support tactical pilots in the rapid assessment of information quality and reconsideration of decisions that the information supports. Such a capability requires an efficient, predictive knowledge base that enables rapid situation assessment and decision support. In Phase II, we will develop the CARP (Configurable Adver ...
