ABSTRACT:The reduction of aerodynamic/hydrodynamic noise caused by violent turbulence is of strategic importance to many military systems. These include modern fighter jets, unmanned weapons with sensitive electronics, and surface and underwater vessels. For all these systems, aerodynamic or hydrodynamic noise can produce unacceptable levels of operational loads or acoustic vibrations, or be detri ...

Spatial Cognition, LLC is nearing the completion of work on Phase I research and development effort entitled Immersive Vision, Data Fusion and Threat Awareness for Enhanced Sensor-to-Shooter Engagement/Targeting. The major goal of this effort is to leverage advances in sensor technology, graphics hardware, and 3D rendering techniques to provide novel visualization capabilities that enhance the sit ...

This proposal is for a Phase II program for further development and prototyping of a Development and Run-time Environment for Aviation Mission-tasking and Mission-management (DREAMM) for manned-unmanned teams.Development and modification of the tightly integrated avionics in a combat aircraft is highly technical and currently requires skilled engineers to effect even the most minor changes in syst ...

With the 4 billion tons of uranium estimated to be dissolved in the earth & apos;s oceans, an essentially unlimited resource is available to those with easy and affordable access. With decades of research towards the extraction of uranium from seawater, focus has been directed towards the selectivity of the adsorbent material, the cost of the material, and the ability of the adsorbent to be recycl ...

Fuel cells convert chemical energy in a fuel directly to electrical power. They have several advantages over other energy sources including: highly efficient energy conversion, fuel flexibility, reduced air pollution, reduced greenhouse gas emissions, reduced oil consumption, and expanded use of renewable power. State-of-the-art Solid Oxide Fuel Cells (SOFC) use lanthanum strontium cobalt iron oxi ...

Opportunities exists to use high moment magnetic nanoparticles CoxFe100-x to replace annealing-stabilized high induction -FeCo phase as the primary phase in the currently used soft magnetic materials (e.g. HITPERM). The key to this development is to design advanced nanocomposites containing high moment nanoparticles for small, lightweight passive inductors, by using an innovative cost-effective ...

To ensure safe and reliable power production by nuclear power plants, a wide variety of materials and components need to undergo inspections and maintenances at pre-determined intervals. Condition based maintenance is highly desirable because it can potentially avoid unnecessarily costly maintenance actions and associated error induced failures. Consequently, it can help achieve nearly all the mai ...

Obsolescence, aging, reliability, and performance issues are driving nuclear facilities to replace conventional analog I & amp;C systems with digital technologies. The increased complexity of digital systems, compared to their analog counterparts, has resulted in faults that are often more difficult to detect, classify, and correct. Experience in the nuclear industry has shown that traditional s ...

No method currently exists for detecting intermittent faults in nuclear power plant cable circuits, which include circuit components, connectors, and end devices. Conventional techniques can locate hard faults, such as open or short circuits, but not the intermittent faults that occur occasionally. Furthermore, conventional testing techniques require circuits to be removed from serv ...

The current installation rate of wind turbine generators is on track to meet DOE published goals of 20% wind source of electricity by 2030. As the most economical sites become populated, future installations will rely more heavily on low wind speed on-shore site locations and high wind speed off-shore or deep off-shore site locations. As higher power density evolves from 2.5 MW to 6-10 MW per turb ...
