The goal of this proposal is to demonstrate the feasibility of new multi-scale models for linking higher order micro-structure descriptions to failure initiation and crack propagation for high cycle fatigue of high strength titanium alloys. This includes new high temperature materials such as the lightweight intermetallic titanium aluminide turbine blades to be used in the lower pressure sections ...

For the Phase I effort, a team comprised of experts in the areas of alternative high performance computing architectures such as the GPU, IBM Cell BE and Field Programmable Gate Arrays (Research Institution), and finite element analysis and continuum mechanics (Global Engineering Research and Technologies) has been formed to design and develop a framework and a library of algorithms optimized for ...

We propose a suite of nonlinear image processing algorithms derived from the analysis of the underlying diffusion geometry of a collection of hyperspectral images of interest. These tools enable the comparison of spatio-spectral features of hyperspectral images acquired under different conditions, for the purposes of target detection, change detection and anomaly assessment. This methodology also ...

In Phase I, NP Photonics has successfully demonstrated the feasibility of a fiber-based THz source that can generate high power, narrow linewidth, and tunable THz radiation by leveraging NP’s proprietary unique fibers, fiber lasers/amplifiers, and THz techniques. In Phase II, we will develop the monolithic high power ~ 2 micron pulsed fiber laser system for the proposed fiber-based THz source un ...

Nonlinear transmission lines offer new vistas in the generation of high power microwave wave (HPM) signals. All electromagnetic sources use an active medium to convert electrical energy to high frequency waves and ultra-wide band signals that can perform useful work. Traditional methods rely on electron beams for the active medium. Nonlinear transmission lines use nonlinear circuit elements to ...

Military applications for the use of directed electromagnetic energy, which include high power microwave (HPM), seek to disrupt electronic systems by exploiting non-linearity in semiconductors. While current mode second breakdown is a thermal non-linearity often exploited, it has been demonstrated that a broad class of semiconductors have more subtle non-linearities that can be utilized to induce ...

Ultra High Temperature Ceramics (UHTC’s) such as zirconium and hafnium diboride based composites are of particular interest for hypersonic leading edges due to their extreme refractoriness. Successful integration into hypersonic structures will require high strength / high temperature joints to bond ceramic-ceramic or ceramic-metal that can sustain the mechanical and thermal loadings at speeds ...
