Prediction of complex dynamical systems is an important task that has implications in a wide variety of technological and policy domains.  Accurate prediction of processes such as terrestrial and space weather, climate change, financial and economic markets, and pandemics can have profound policy and engineering impacts.  As a result, diverse methods of time series prediction have been developed ...

TAF proposes to Reverse Engineer the McNab Circuit Card Assembly, NSN identified by DLA, 5998-01-276-2156, using available adjacent and salvaged parts. TAF will create a Technical Data Package (TDP), manufacture and test prototypes, develop a Source Approval Request package, and ultimately deliver 5-10 working sample parts for Source Approval. The NSN is a critical Circuit Card Assembly — more c ...

The Air Force desires to procure parts to Drawing WRG95936, however, obsolesce of materials and the loss of the previous supplier no longer in this business, makes finding an alternative source necessary. Validation of new materials is required. Chase has the pedigree history from the previous source and relative experience to assure form, fit, functionality of the new part.

Geomagnetically induced current (GIC) hazard is a recognized threat to the United States power system. Federal models to support hazard specification and prediction for critical infrastructure are at an advanced state, including models of space weather, the Earth’s conductive structure, and regional geoelectric field. We propose to use existing NOAA Space Weather Prediction Center (NOAA-SWPC) mo ...

Localization of over water airborne contacts by a ship at sea or a land-based collector, typically requires either active sensing of the target or a combination of passive measurements from two or more cooperative platforms sharing information about either the time and frequency of arrival or angle of arrival of the RF energy from the aircraft. In both of those cases the friendly platforms are una ...

Today, overwater emitter localization is performed using a combination of direction finding and/or multilateration. Both techniques inherently require multiple, well-separated receivers determine 3D emitter locations. The lensing effects of atmospheric ducting and surface reflections can potentially produce near-field phenomena whereby the electric fields received from an emitter is sensitive to t ...

The project aims to grow device-quality InxGa1-xN, an important semiconductor because the band gap can be shifted widely by varying x, using a new form of plasma sputtering, Biased-Target Deposition (BTD). The major objectives are to grow x > 0.05 material on sapphire at 600-800°C (standard) and 300-500°C (beneficially reduced) temperatures, and to characterize material quality via X-ray diffra ...

Close Air Support (CAS) is playing an increasing role in military operations. The emphasis on Special Operations in recent years has increased the combat range of small units, often sending squad-sized units hundreds of miles behind enemy lines. Small units rely on stealth and airpower. They remain covert, but when they are discovered, they call in airpower to keep from being outgunned. All too of ...

Many modern approaches to autonomy use a layered planning technique where a conventional path planner plans a nominal desired path, and a reactive planner plans trajectories over a local region. In relatively structured environments with good localization, this layered approach has been proven to work well, as shown by TORC’s successful 3rd place entry in the 2007 DARPA Urban Challenge. The ov ...

With the significant advancements in motor efficiency and energy storage technology, electric propulsion systems have become viable power plants and power supplements to aircraft. Offering high power-to-weight ratios, electric drive systems significantly increase the design capabilities for vertical takeoff and landing (VTOL) capable platforms. Ducted fans offer the ability to develop an enclosed ...
