A study of Mo-Si-B-XX alloys for high temperature structural applications is proposed. The material for such applications require strength, ductility, toughness, fatigue and creep resistance, and oxidation resistance. The Mo-Si-B alloy system provides an opportunity to develop desired properties. The alloy processing and microstructure synthesis will be pursued. The deformation mechanisms wil ...

Photon-X, University of Pennsylvania (UPenn) and University of Washington (UW) are teaming to propose to develop next generation EO modulators based on photonic crystal (PhC) waveguides and stable functional polymeric materials that would provide revolutionary performance for broad range of applications. We will design and analyze PhC modulators based on highly stable advanced NLO polymers and d ...

ABSTRACT: Future hypersonic vehicles, like X-43 and X-51 derivatives and Falcon HTV-3, will require advanced strategies for thermal protection systems (TPS) and methods of structural integration. The goal in designing TPS for these types of high performance applications is to establish multi-mission reusable systems with reduced weight and increased performance that possess multifunctionality, e ...

ABSTRACT: ADI and ASU propose to develop a novel methodology for blade peak stress prediction from limited strain gage/tip-timing measurements when multiple vibratory modes are present. The current protocol assumes that only one mode is present and only provides upper and lower bound estimates of the blade peak stress when multiple modes are important. It is proposed here to construct the blade m ...

ABSTRACT: In the future, numerous military database, documentation, and mission-critical information systems will be migrated to the clouds, due to cloud cost-efficiency and accessing flexibility. However, the cloud servers are generally untrusted either for data owners or users. In this proposal, A3IS (Attribute-based Algorithms for Assured Information Sharing) is proposed for dynamically and se ...

We propose a comprehensive software tool called ModelTime(TM)for the design, analysis and construction of multi-core software for distributed real-time systems using a model-based design methodology. ModelTime will use UML-like diagrams to capture networked multi-core platforms, software components and configurations, functional and para-functional attributes like end-to-end timing constraints, a ...

Overwhelming heat and clocking considerations have led to the accelerating rise of multicore processors. The number of cores per chip is expected to increase rapidly in coming years. In fact, chips with 100 cores and prototypes with 128 cores are already available. As the number of cores increases, the scalability of the operating system(s) will become a major bottleneck, particularly for embedd ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...
