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 ...

The objective of this proposal is to demonstrate the feasibility of a new thromboelastograph (TEG)-like instrument that has the same basic capabilities as the TEG – that is to say, capabilities of monitoring in vitro the kinetics, strength, and stability of clot formation in blood samples that are clot induced – but which is miniaturized, highly portable, rugged, and insensitive to adverse env ...

The objective of this Project is to explore and develop refractory coatings on high strength, high electrical conductivity copper alloy, to enable damage resistant electromagnetic launcher. An electromagnetic launcher consists of two parallel copper rails, and a moving armature. High electrical currents passing through the rails and armature result in strong magnetic fields, high temperatures, che ...

Nanotrons Corporation, in collaboration with Professor Byungki Kim at NSF Nanomanufacturing Research Center at the University of Massachusetts Lowell (UML), proposes to develop the low-cost high-rate manufacturing technique for flexible explosive detection sensors to significantly increase sensitivity of detection of trinitrotoluene (TNT) explosives. The new approach combines cutting-edge nanomate ...

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 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 ...

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 ...

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 ...
