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 broadband antenna, having more than a 100:1 bandwidth,is integrated with a high impedance surface that is compatible with the manufacturing processes associated with with Navy topside panel constructions and marine vehicle armor. The high impedance surface (also known as an artificial magnetic conductor, or AMC) can be tuned to discrete frequency bands using voltage-variable capacitors and the o ...

We propose to design a high average power Er:Fiber ultrafast laser system which is pumped at 14xxnm, and at the same time solve other problems related to ultrashort pulses in fiber lasers. The advantage of using 14xxnm pumping is the reduction of the standard quantum defect from 37% to 5%, thus greatly reducing the thermal load on the system, which makes it inherently more efficient. We also inten ...

This Small Business Technology Transfer Research (STTR) Phase II proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline tungstate ceramics with densities greater than 99.95% and a mean grain size of less than 1 um. These ceramics have been chosen because of their low thermal expansion and low elastic ...

The Phase I deliverable will be a physic-based model which represents a CMC gas turbine component concomitantly at the material level and the structural level. This model will be probabilistically analyzed to account for the uncertainties in material properties and the uncertainties in the size and impact velocities of possible foreign objects (FOD). A ceramic material must display sufficient capa ...

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 ...

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 ...

While there are established methods available in determining the fatigue life of critical rotating components, there is still room for improvement for better understanding and prediction of life limiting factors. Improved risk assessment of jet engine disk components would require probabilistic modeling capability of the evolution of microstructural features, residual stresses and material anomali ...

In any large-scale training exercise, it is difficult to provide all trainees with training objectives commensurate with their skills levels, experience or expertise. The TARGETS and EBAT training and performance measurement methodologies were developed by Dr. Eduardo Salas at UCF. In this project, we are utilizing TARGETS and EBAT to develop a software toolkit that is integrated with the CDMTS si ...
