Not Available Because of a fortuitous combination of high density, high light yield, and fast decay time a cerium-doped rare earth orthophosphate (REOP) crystal, Ce:LuPO4, offers an opportunity to improve detection of x-rays and gamma-rays. A new approach to high temperature solutioin (HTS) growth of CE:LuPO4 crystals is proposed. The Phase I research will test the feasibility of using a novel ...

Development of three Bipropellant Tank designs with mechanically linked pistons for Advanced Small Missile Systems. The study will consider the technical and fabrication issues associated with the design, and rate the comparative merits leading to the selection of Phase II continuation.

The objective of the proposed research is to develop new technologies based on principles of Time Reversal Acoustics (TRA) that will provide highly sensitive land mine detection. We suggest applying the Time Reversal Acousto-seismic method in combination with a nonlinear acousto-seismic mine detection technique. The TRA focused system provides a high concentration of seismic wave energy at any des ...

The objective of this proposal is to develop a Muscle Water Content (MWC) sensor, an ultrasonic device for assessment of body hydration status in soldiers with accuracy better than 2% during deployment and training. The MWC assessment is based on measurement of ultrasound velocity in muscle, which is, to a good approximation, a linear function of the water content. The expected outcome will be ...

This proposal develops an extremely low cost fiber grating corrosion sensor system that could be deployed on a vehicle. Costs are estimated to be approximately $0.25 per sensor in volume allowing hundreds to be deployed if necessary on difficult to access areas of a ground vehicle. In order to keep costs to an absolute minimum it is anitipated that the read out unit would be maintenance rather t ...

Not Available This Small Business Innovation Research Phase I project is to develop a set of innovative and efficient optimization algorithms/tools for uni- and multi-objective design and placement optimization of passive and active elements of smart structures, primarily in a massively parallel environment. The objective functions to be minimized will include structural weight or cost function ...

Not Available The objective of this proposed SBIR is to develop new commercially affordable high power, high efficient microwave power amplifiers based on GaN heterostructure field effect transistors (HFET). Compact, lightweight and efficient microwave power amplifiers are needed for BMDO mobile radar systems application. GaN HFET has been demonstrated under the sponsorship of a BMDO program to h ...

The objective of this proposal is to demonstrate the feasibility of an innovative engine fuel filter design that utilizes water-selective membrane technology to separate water and debris from the diesel fuel. This advanced design combines a cross-flow membrane element, a fuel by-pass valve, water detection sensor, and an automatic filter service life monitor into one fuel filter unit, which is de ...

We propose to develop and assess an Orthogonal CDMA cellular communications system that capitalizes on the advantages associated with a unique pseudonoise (PN) code class identified as "Multiplexed Noise" (MN) codes. Employing MN codes for CDMA eliminates all of the major disadvantages of present CDMA systems that employ Maximal Length Sequence (MLS) codes. Those systems are forced to be non-orth ...

Not Available The threat of proliferation of chemical and biological weapons has increased alarmingly in recent years. Treaty monitoring and verification activities require the rapid collection and chemical analysis of samples at suspected chemical warfare (CW) agent-producing facilities. Current on-site analysis procedures are slow, thus hindering the effectiveness of verification operations. ...
