The Fast Fourier Transform (FFT), an efficient method for computing Discrete Fourier Transforms, is widely used in climate modeling, molecular dynamics, structural dynamics, astronomical computations, nuclear energy, and many other scientific applications. Representing one of the most important users of numerical routines, the Department of Energy (DOE) uses FFTs to solve the most-pressing challen ...

Organophosphorus chemical warfare nerve agents (OP-CWA) are attractive to terrorist groups and rogue states as an inexpensive and accessible technology for chemical warfare. OP-CWA and organophosphate pesticides cause severe neurological symptoms and death by inhibiting the enzyme acetylcholinesterase (AChE); the resulting excess acetylcholine accumulates and overstimulates the human or animal bo ...

There is significant opportunity for energy efficiency improvements in the industrial and manufacturing sectors in the U.S., both from the production and consumption perspective. Higher energy density battery materials will play a role in both, through improved storage of electricity from renewable sources, the enabling of electric vehicles, and through the development of longer lasting, higher po ...

The extraction of dilute concentrations of alcohol from water is one that is widespread through industry and environmental clean-up. It is presently separated by distillation processes, where possible, a technique which is energy intensive and has impacts on product cost and the environment through the use of fossil fuels to supply the energy needed. This problem has a enormous impact on the cost ...

The U.S. Department of Energy is developing technologies to expand and improve the U.S.

Wind power has an important role in satisfying the power needs of the United States. Since wind power is a clean renewable source of energy, it also serves an important role in reducing dependence on fossil fuels, in particular foreign oil supplies, as well as reducing greenhouse gas and carbon emissions. Unfortunately, significant maintenance costs, recently highlighted by a series of blade failu ...

Ice crystals can form spontaneously from the freezing of water droplets at temperatures colder than -38

Today's Web portals for science only provide sparse coverage of the communities they seek to serve, typically less than 5%, because comprehensive coverage is too hard to do. This project will develop a suite if tools (which we call the X-Portal technology, where X is the community to be served), to make comprehensive coverage workable. A number of clustering methods will be collected, tested and l ...
