The purpose of this project is to demonstrate the effectiveness of using an innovative deposition process for making Sm2Fe17Nx/á-Fe16N2 magnetic materials in bulk quantities. In addition, exchange-coupled nanostructured composites of these materials will be produced. The advantage of this process is that it allows precise control over the deposition ions so that the morphology of the materials ca ...

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 Point Method) - MFM (Multiphase Flow Method) approach and CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. CartaB ...

This project will develop a data driven prognostic fault tolerant smart weapon system concept for the Airborne Laser. A real-time prognostic health management (PHM) system will be developed to track the likelihood of future system or subsystem failures and initiate or indicate appropriate actions to maintain or optimize system performance. A library of predictive algorithms will be employed to tak ...

ACTA Incorporated and the Center for Systems Reliability (CSR) at Sandia National Laboratories propose a seven month STTR Phase I Project to demonstrate the feasibility of developing Fault Diagnostics, Prognostics, and Self-Healing Control of Navy Electric Machinery. The new generation of Navy high power electric ships and electro-mechanical machinery challenge the predictive maintenance of ships ...

The overall objective of this project is to develop an automatic adaptive testing system that rapidly identifies specific cognitive deficits to aid in medical and operational decision making. This system will greatly increase the usability of test systems developed under Army sponsorship during the last 20 years, resulting in a product with broad application in both military and civilian environm ...

This STTR provides the Navy with a unique opportunity to fundamentally change the way ship design and analysis is accomplished by defining in Phase I the tools and computational infrastructure required to integrate selected individual specialty design and analysis tools into an overall Naval Engineering Analysis Tool (NEAT). NEAT, when mature has the potential to significantly reduce the design a ...

Game-based training (GBT) has been touted as a promising medium for achieving improved training objective performance outcomes and increasing learner motivation, particularly in military training environments. However, there is little empirical research upon which to make informed decisions about when, where, or even if applying particular game elements to training is effective. The primary object ...

Determining a geo-reference of an underwater object is a critical requirement for marine applications such as mine-hunting and marine surveying. Although a GPS fix can be obtained at the surface, the watch circle of a tether connecting a surface and underwater body can impose positional errors that are far greater than GPS errors. Here we propose to develop a technology to automatically determin ...

Localizing low frequency noise sources in shallow water using a horizontal array is complicated by waveguide dispersion and maneuverability constraints. If the dispersive properties of the sound propagation channel are well known, waveguide effects can be used advantageously for the purpose of localizing sources without requiring a relative change in bearing to the target. Here we propose to inve ...

Off-board vehicles deployed in littoral environments are subjected to severe operational loads, including wave slamming, high-speed collision with debris, and underwater explosions. They additionally serve as sensor platforms, and would benefit from reduced self- and radiated noise for towed array performance and mine defense. Consequently, we propose to exploit the flexibility of design offered ...
