ABSTRACT: Composite materials are increasingly adopted into Aerospace application due to their superior specific strength/stiffness, resistance to fatigue and ability to reduce part-count. Furthermore, it has been demonstrated that by introducing carbon nanotubes (CNTs), multi-functional capabilities can be achieved by virtue of their high conductivity and piezoresistive nature. During the prop ...

ABSTRACT: In collaboration with Sandia National Laboratory, Physical Sciences Inc (PSI) proposes to design, develop, and demonstrate a Frequency Agile Terahertz Sensor (FATS) for trace explosives residue detection. The critical frequency agile terahertz (THz) detector is based on an electronically tunable plasmonic grating-gate technology developed by our collaborators at Sandia. The Phase I ...

ABSTRACT: The team of MicroXact, Inc., UCLA, UC Irvine and Carnegie Mellon University proposes to engineer revolutionary nonvolatile reconfigurable plasmonic gates for information processing on the basis of ultrafast plasmon-enhanced all-optical magnetization switching. This unique approach allows one to program any gate between several different states at very high modulation rates and low power ...

Phase II research will follow the most promising leads developed in Phase I, with the end goal of developing a viable physics-based model that can explain observations available to the Government. A dispersive focusing mechanism, supplemented by the theory of cylindrically-symmetric solitons, is the most promising mechanism identified in Phase I. Three related tasks will be performed: Detailed th ...

Large Scale Training exercises, such as the Fleet Synthetic Training Joint (FST-J), demand extensive resources and effective planning. Prioritization of training events, alone, cannot guarantee that the training objectives for every trainee can be met; particularly in environments where participants are performing different roles and are disparately skilled. A new solution is needed to manage the ...

This Phase II effort will establish photovoltaics modules that offer high efficiency (>12%) and can be flexed, stretched, twisted, and deformed (to strains of>30%) in ways that enable conformable wrapping of complex, curvilinear shapes and fabrics. The application opportunities for photovoltaics using this approach include systems that intimately integrate with the curved surfaces of structural co ...

In order for the military to achieve its desired electronic warfare goal of dominating the electromagnetic spectrum it is critical that new technology paradigms for electronic warfare support be vigorously explored and developed. The STTR proposal being submitted by the joint team of Salbec, LLC and Boston College breaks away from the conventional approach of using antennas for RF EM sensing and p ...

The proposed Automated Linguistic Analysis Revealing Misrepresentation and Messaging (ALARMM) system significantly advances the state of the art in detecting deception in unstructured data such as websites and chat messages. Our research focuses on automated techniques based on linguistic theory that can detect both misrepresentations and hidden messages. The proposed work draws on the field of so ...

The US Navy requires advanced power systems for emerging autonomous underwater vehicle platforms, and hydrogen/oxygen fuel cells have been identified as a suitable replacement for the costly and hazardous primary lithium batteries currently in use. Giner Electrochemical Systems, LLC (GES) and Purdue have teamed to demonstrate a novel chemical hydride fueling solution that will enable onboard hydro ...

A boats coxswain is adept at analyzing the wave environment, adjusting the crafts propulsion system and control surfaces to mitigate its motions and reduce the chance of capsizing. There is a significant predictive component in the coxswains control decisions. Unmanned surface vehicles (USVs) lack the benefit of a highly trained coxswain reading and predicting oncoming waves - existing autonomous ...
