Network security is a key issue for the successful implementation of the ESnet and the collaborative/grid environment for DOE science. As identified by DOE, network security includes self-defensive networks, firewall compatibility across different domains, and user authentication and authorization. Of particular interest is defense against worms, a highly problematic and dangerous threat because ...

The DOE-sponsored U.S. High Gradient Collaboration has determined that U.S. efforts should attempt to achieve the highest practical accelerator gradient in a working frequency range of 11.4 to 30 GHz. Although recent CERN studies suggest that 20 GHz is a near optimum value, facilities for conducting high gradient accelerator research are available only at 11.4 GHz in the U.S. (SLAC) and at 30 GHz ...

Advances in bioinformatics and genome research have generated a rapid expansion in the availability of information at all levels of biological investigation. One of the goals of the of the DOE¿s Genomes-to-Life Program is the development of a computational systems-biology infrastructure, in order to interpret this information at the whole cell level and to predict the behavior of these complex s ...

The exploration and production (E&P) of oil and natural gas is one of the most computationally demanding endeavors, generating terabytes of data. To optimize the management of a producing oil field or to find new reserves, the E&P data must be readily available to a multidisciplinary asset management team. The data must be easy to access, and it must be effectively managed by a team of geologist ...

PROJECT SUMMARY To make simulation-based exercise development efficient, it is important that scenarios be developed and executed ¿on-the-fly¿ in an automated fashion with minimal reliance on software personnel. To this end, what is needed is an intelligent scenario/script building capability that enables training personnel to rapidly assemble and ¿test-drive¿ incident scenarios, and that can ...

The video surveillance industry is experiencing dramatic change with the move from analog to digital video. Command centers need to have coordinated viewing of multiple camera feeds at one time, and the ability to switch automatically between feeds and display relevant patterns. Conventional security control rooms include a bank of monitors connected through a switch to an array of security camera ...

The ideal biological imaging system would provide non-invasive, high-resolution, high-sensitivity three-dimensional (3D) images of living systems. Positron Emission Tomography (PET) offers high sensitivity to a range of biological processes through the use of targeted radiolabeled probes. Unfortunately, precise signal localization can be extremely difficult, due to low spatial resolution and the ...

Future progress in understanding particle physics will require higher energy collisions, which in turn will require more energy and luminosity. More luminosity means larger apertures and bigger magnets, which in turn will require higher-performance lower-cost superconductors. This project will develop and demonstrate a low cost powder-in-tube (PIT) multifilament Bi2212 process with improved fila ...

Optical detectors are a very important component of both existing and future particle physics experiments, including those being developed for dark matter studies. However, for dark matter studies, the expected performance of experimental systems is limited by the properties of presently available optical detectors. This project will investigate new, robust, large-area avalanche photodiodes (APD ...

In border security applications for remote deployment, with no existing infrastructure or roadways as well as areas with dense foliage, a promising technology is the use of unattended ground sensors (UGS). While there has been a great deal of research and development in the areas of UGS and wireless sensor networks (WSN) over the last decade, traditional use of these technologies suffers from eith ...
