Traumatic head and neck injuries account for 16-33% of all war-related injuries and are a leading cause of mortality upon evacuation to a definitive care setting. This application is focused on treating one of the most important determinants of outcome from severe head injury, the degree and duration of elevated intracranial pressure (ICP). The main objective of this proposal is to continue the ...

Optical measurements including laser velocimetry (LV), particle image velocimetry (PIV), and other similar techniques are becoming a more important part of aerodynamic testing. However their implementation into large production wind tunnels is severely hindered by difficulties with flow seeding. Phase I of this program will focus on the problem of seed delivery and dispersal into a transonic strea ...

The use of carnauba wax in melt/castable explosives yields a insensitive explosive formulation that enhances overall safety for the use of these munitions in the field. However, carnauba wax is only obtained from overseas sources and there is no domestic source for this material. This leads to shortages of material and higher prices. There exists a need for a wax substitute to replace the carna ...

Internal Combustion engines (IC) are bound in their ability to create power primarily by the volume of air an engine is able to deliver to the combustion chamber. This formula has particular import at high altitude, where air pressure decreases, resulting in a correlative power loss. Traditional solutions for generating higher compensating air pressure are limited to external add-on devices such ...

In order to capture incoming data streams at tens of terabits per second continuously or for tens of minutes, it is useful to preprocess the data as close to the collector as possible, then make either the digested data or raw segments of interest available via conventional networking and remote files. This proposal adapts and demonstrates FTL Systems’ COTS embedded supercomputer, StarStream, t ...

Deriving coherent antenna array clocks from a common tapped delay line driven by a synchronizing pulse per clock cycle results in reduced jitter and optimal beam forming at minimal cost. Phase one effort analytically considers both electronic and optical implementations with an option for simulation-based validation of a critical PLL circuit and other physical parameters. Analysis considers three ...

Existing search technology is inadequate for addressing the information retrieval requirements of today's complex tasks that require the integration of information from multiple and heterogeneous sources, the discovery of arbitrary and non-obvious relations between the documents, and the uncovering of information that is intentionally trying to hide. The goal of this project is to advance the stat ...

The objective of this proposal is to demonstrate the feasibility of producing a tactical secure narrowband voice/variable data rate (VDR) over Internet Protocol (IP) inter working function (IWF) method without sacrificing the security of the voice communications or wasting the limited available bandwidth. The primary challenges with introducing security into voice over IP (VoIP) systems are 1) var ...

The US Navy is interested in analytical methods and tools to predict ship bubbly wake acoustic signatures for waterjet propelled surface ships with underwater waterjet outlet such as the Littoral Combat Ship (LCS). Wake features of propeller-driven ships are well studied, but the ability to perform predictive analysis and wakes from waterjet driven advanced hull forms do not currently exist. The m ...

The gradual degradation of wiring systems in aircraft is a serious concern plaguing the Air Force's aging fleet. It has been observed that the majority of wire breakage problems occur within nine inches of the connector, terminal lug, or other junction. In many cases, the wiring was not properly relieved of strain near the junction points. Traditional wires are by nature inelastic under stress, ...
