Areas of research relating to self-healing composites structures have been undertaken by well-known and respected institutions under the auspices of the Department of Defense. Patent literature and public technical communiqué describe their novel engineering approaches using microencapsulated systems that release polymeric healing agents through suitable mechanisms. While these approaches have me ...

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 ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

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 ...

Having realized the bottlenecks in electronic systems-on-film manufacturing, Omega Optics and the University of Texas at Austin propose to develop a low-cost, high rate, roll-to-roll manufacturing process for hybrid electronic systems on flexible substrates. Roll-to-roll fabrication of hybrid systems enables the utilization of the combined advantages of organic, inorganic and other material system ...

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

The U.S. Navy has initiated a program to develop the next-generation Joint Counter Radio Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.3 system to detect and jam enemy improvised explosive devices (IEDs). The objective of this proposed effort is to develop the manufacturing processes and antenna designs needed to integrate a wideband metamaterial antenna within the ballistic ...

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 ...

21CT and CUBRC propose CEDAR (Complex Event Discovery, Analysis, and Ranking), a robust framework to detect and analyze indicators of complex activities, such as an insurgent ambush observable via myriad of simple events in multiple sensor streams. CEDAR will provide a mapping from complex behavior, such as conducting an insurgent ambush or rebuilding trust in local communities, to simple event in ...

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 Web sites 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 s ...
