This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army. The proposed algorithm is based on the FLIP (Fluid Implicit Particle) - MPM (Material PointMethod) - MFM (Multiphase Flow Method) approach and the CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory.

We propose to investigate innovative, wideband, traveling-wave tubes (TWTs) compatible with three-dimensional (3D) micro-electro-mechanical systems (MEMS) fabrication techniques for millimeter or sub-millimeter wave applications. At least three novelinteraction circuits designed around MEMS fabrication technology will be investigated, as well as a novel electron beam source using field emission a ...

From consultations with the Army program manager, it was determined that the Army has a strong need for improved amplifiers in the W band. Accordingly, the proposed Phase II overall technical objective is to develop a 10 W, W-band prototype planar helix TWT. In Phase I, we addressed improving the repeatability, cost and yields of conventional Ka-band TWTs by introducing novel circuits, beam sou ...

In Phase I a revolutionary system for digital imaging microscopy was demonstrated. The system is based on the newly-developed imaging technology of Wavefront Coding (WFC). WFC employs specialized aspheric optics and digital processing to greatly increasethe depth of field or depth of focus. WFC simultaneously decreases the size, weight, and cost of a variety of digital imaging systems. Depth o ...

The Phase I program objectives were successfully completed. In addition, novel ideas were developed that will be of use in the Phase II program and in the field of algorithm development and sensor characterization in the laboratory. Work on new algorithmswas initiated to optimize wavelength selection for vapor and aerosol detection, a detailed design for obtaining sensor detection statistics in th ...

"To be commercially competitive, PEM fuel cells have to be able to run on readily available fuels. Fuel reformers are practical, but fuel cell anode catalysts are severely poisoned by small quantities of carbon monoxide from the reformer. Despite mucheffort invested into increasing CO tolerance, desired performance levels have not been achieved.Recent data has shown great promise in mitigating t ...
