We propose to develop scripting language enhancements to enable the rapid synthesis of publish-subscribe fuselets through a unified framework for subscription and resource discovery based on XPath and XQL extensions, to design and prototype itsimplementation in an extensible manner by mapping onto existing interpreter and runtime infrastructures using a combination of dynamic source-to-source tran ...

We propose to define a universal graphics interchange format which extends existing Extensible Markup Language (XML) graphics languages such as SVG and XGL so as to enable portability among display formats for the test and evaluation (T&E) of aircraft andspace systems, to design a unified framework for interoperability which specifies mappings between formats as multi-stage XML StyleSheet Transfor ...

The objective of this proposal is to develop Selective Availability Anti-Spoofing Module (SAASM) compliant GPS receiver for Geosynchronous Earth Orbit (GEO) applications. In this proposal, we explore an approach to design the GEO GPS SAASM receiver based on improved techniques for signal acquisition (or detection) and then signal tracking (and demodulation) of weak GPS signals. GPS signals availa ...

ABSTRACT:Emergence and feasibility for flexible body-worn electronics and particularly medical patches requires high performance electronics capability.The problem is that these new technologies must have flexible and conformal physical formats and conventional electronic components are not in any way flexible. In the CLAS Phase I program, a new flexible high-performance manufacturing and material ...

Electric vehicles, including hybrids in the nearer term, are the principal transportation technology by which the United States can become independent of foreign oil, can become energy independent overall, and can effect control over greenhouse emissions. For this to become reality, electric vehicle costs need to come down and performance needs to improve. For electric vehicle motors, the goals ...

ScienceTomorrow in collaboration with Dr. David C Joy, at the University of Tennessee Research is proposed to fabricate direct digital Quantitative Secondary Electron Detectors (QSED) for scanning electron microscopes (SEMs). If successful, commercial versions of the QSED would transform the SEM/STEM into a quantitative, metrological tool with enhanced capabilities that, in turn, would broaden re ...

ABSTRACT: This project will investigate the feasibility of a computing appliance which uses Temporal Virtualization to help ameliorate the effects of malicious software activity. Temporal Virtualization involves the manipulation of virtual time in Type-2 (software) virtual clients in a way that frustrates an adversary"s attempts to corrupt or break out of virtualization. An attack model is assume ...

ABSTRACT: To address the needs of the U.S. Air Force to improve existing software design packages so that they account better for short crack growth regime, Sentient proposes to incorporate its its DigitalClone-Component(DCC) modeling technology into these packages for short crack growth regime. The use of fracture mechanics to characterize the growth of fatigue cracks in metals is well establish ...

ABSTRACT: The ability to access high-quality training anywhere and anytime continues to grow in importance due to the complex nature of operational team environments. Training simulations that use virtual agents that respond and behave like live teammates enhance training and help achieve the train as you fight objective without requiring a complete team of human participants. However, the domain ...

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. ...
