Trauma is a leading cause of both military and civilian mortality, accounting for roughly 10% of all deaths worldwide. Coagulopathy (disturbance of the physiologic balance between bleeding and clotting) is observed in 25% to 36% of trauma patients and significantly increases mortality. Trauma-related coagulopathy typically involves dysfunction or depletion of coagulation factors, platelets, fibrin ...

Analysts are faced with the challenge of sifting through enormous quantities of documents, blog posts, communications, etc. to find deceptive behaviors. We propose novel techniques for efficiently and automatically detecting deception on large data with high accuracy by using methodologies from both stylometry and topic modeling. This combined approach will learn models of authors and will detect ...

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 ...

Collaboration, always the bane of effective operations, has seen numerous advances towards providing solutions for concurrent action, immersion within the domain, knowledge mining within a common perspective, and inculcation of stakeholder’s defined robots. Google Wave is at the forefront for making these capabilities available all within a web environment, and Systems Engineering Solutions, Inc ...

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 ...

We propose to conduct a feasibility study for utilizing broadband sampling of the diffusive noise field in a dynamic environment. In ambient noise studies, the ability to resolve a wavefield is proportional to its time-bandwidth (TB) product. In a dynamic environment such as in the atmosphere or ocean, the nature of the impinging wave field is changing rapidly so that only short time segments can ...

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 ...

The overall objective of the Phase I and Phase II proposed effort is to design and demonstrate the ability to develop a high-speed shock tolerant composite flywheel energy storage system (FESS) using a low cost manufacturing process. The Phase I tradeoff design studies will assess the FESS size, operating speeds and material requirements needed to achieve the energy density levels and charge/disch ...

Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased performance. However, a drawback of this technology is that individual blades cannot be easily repl ...

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...
