Network-centric command and control of complex military missions (e.g., anti-submarine warfare, collaborative mine hunting, etc.) calls for cost-effective designs that can dynamically tradeoff multiple conflicting objectives. Often these optimizations have to be carried out at a higher level, and the associated control directives have to be disseminated down to a distributed system, thereby, influ ...

The key innovation of this proposal is to develop an adaptive and scalable network resource virtualization framework. The framework employs simple yet efficient mechanisms to deliver a comprehensive network resource virtualization solution through network virtualization, service discovery/advertisement, and service differentiation in mobile ad hoc networks (MANETs). It uses local caching to facili ...

The exponential growth of text-based communication associated with the Internet has lead to a vast increase in the amount of unstructured messages that open source intelligence needs to process. This increase has lead to the need to develop methods for facilitating the detection of deception in various forms of text-based messages, from chat rooms, emails, weblogs, to text messaging. Methods are r ...

A unique type of air lubricated thrust bearing called a Wave Bearing is proposed to assist a rolling element bearing to carry the thrust load and to improve the bearing’s life when used in a micro gas turbine engine. The Wave Bearing technology will provide improved reliability, safety and life compared to rolling element bearings used alone, as well as to allow simplification of engine design a ...

The objective of this proposed Small Business Technology Transfer (STTR) effort is to develop an experimentally-validated, highly detailed chemical kinetic reference model of surface chemistry for C-SiC-SiO2 rubber composite materials exposed to high temperature, high pressure, oxidizing environments. This reference model will then be reduced into simplified reduced-order models that could be easi ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

Physical Sciences Inc. (PSI), in partnership with the Electrical Engineering Department of the Worcester Polytechnic Institute (WPI), proposes to compute and reduce mutual coupling between E-field antennas (in Transmit mode) and SQUIDs magnetic loops (in Receive mode) for improved signal reception in SQIF arrays. For the computation of the mutual coupling in the near field PSI and WPI will use an ...

APS has assembled a world class team to address problems associated with rail gun launcher operation. APS has combined its unique processing experience with IAT's railgun design, testing and characterization experience to develop materials to improve rail gun performance. Phase I will be devoted to fabrication and testing of various samples in rail gun conditions. Phase II will focus on the manufa ...

The Navy is developing an electromagnetic (EM) launcher for long-range naval surface-fire-support. Severe operating conditions of the EM system place stringent requirements for materials, including high current and magnetic fields, high temperatures, contact with liquid metals, high stress/gouging from balloting contacts and high-speed-sliding electrical-contact with an Al armature. Engineered Coa ...

There is need for fast, easy-to-operate, and low-risk methods for mapping geography, velocity, and bathymetry of rivers. River charts can be nonexistent or inadequate because of changes in water volume, tides, sediment transport, flooding, and other events. This is a hindrance and a hazard for navigation and other operations. Currently, procedures to map rivers involve navigating surface vessels i ...
