AccessData is proposing enhancements to its Distributed Network Attack (DNA)product to increase the functionality which will increase the number of workstations that can participate in the system; from approximately 1,000 to potentially 1,000,000 workstations. This will be accomplished by coupling its world class password attack technology with a proven open source desktop grid computing infrastru ...

THE DEVELOPMENT OF A LIQUID HELIUM TEMPERATURE CRYOCOOLER ISPLANNED. A REGENERATIVE CRYOCOOLER WILL PROVIDE A 20 K TEMPERATURE SINK OF A JOULE-THOMSON (J-T) STAGE USING HELIUM. AN INNOVATIVE DESIGN FOR THE J-T STAGE HEAT EXCHANGERS WILL ALLOW THE USE OF SIMPLE, HERMETIC COMPRESSORS, WHICH WILL MAKE A PORTABLE, LONG LIFETIME UNIT POSSIBLE. THE STUDY WILL FOCUS ON SYSTEMS HAVING A COOLING POWER OF L ...

The long-term monitoring of groundwater contamination plumes to determine the fate of contaminants in the environment is expensive and labor intensive. Current baseline methods have resulted in monitoring programs that collect less data than is required to fully understand the fate and transport mechanisms of the contaminants. In this project, an automated field-deployable monitoring system, whi ...

ALUMINUM NITRIDE (A1N) IS AN IMPORTANT CANDIDATE MATERIAL FOR ADVANCED PACKAGING OF INTEGRATED CIRCUITS AS A HIGH THERMAL CONDUCTIVITY ALTERNATIVE TO BERYLLIUM OXIDE THAT COULD POTENTIALLY BE MADE AVAILABLE AT LOW COST. MUCH EXPERIMENTAL WORK HAS BEEN CONDUCTED ON A1N, BUT THE TECHNOLOGY STILL HAS NOT REACHED A LEVEL SUITABLE FOR APPLICATION. ADVANCES ARE NEEDED ESPECIALLY IN SINTERING TECHNOLOGY ...

OVER THE PAST FEW YEARS, A NEW FAMILY OF MATERIALS CALLED NZP (NAZR2 (PO4)3 AND ITS ANALOGS) HAS BECOME WELL KNOWN FORITS LOW THERMAL EXPANSION BEHAVIOR. RECENTLY, IT HAS BEEN SHOWN THAT ZR4 (PO4)6 AND SRZR4(PO4)6 HAVE OPPOSITE ANISOTROPY IN THERMAL EXPANSION AS WELL AS OPPOSITE BULK THERMAL EXPANSION AND THAT THEIR SOLID SOLUTION RESULTS IN LOWER ANISOTROPY AND NEAR ZERO THERMAL EXPANSION. THESE ...

CERAMIC-MATRIX COMPOSITES WITH OPTIMUM FIBER-MATRIX INTERFACIAL BONDING EXHIBIT HIGH STRENGTHS, FRACTURE TOUGHNESS, AND A DAMAGE-INSENSITIVE FAILURE MODE, AND THEY ARE VASTLY SUPERIOR IN RELIABILITY TO MONOLITHIC CERAMICS. THE DESIGN AND FABRICATION OF THESE COMPOSITES REQUIRE INNOVATIVE TECHNIQUES TO CONTROL, MODIFY, AND CHARACTERIZE THE FIBER-MATRIX BONDING. TWO NOVEL TECHNIQUES FOR MEASURING TH ...

The speed at which an attack is detected is a critical trigger for all responses to follow. The accurate determination of the type of attack will determine the type of emergency personnel and response needed. The location will determine the target response area as well as determine by proximity which of the responders that are available can be first on the scene. Therefore, a system that can do th ...

Volatile natural gas prices are negatively impacting the U.S. industrial sector, which consumes approximately 6.6 trillion cubic feet of natural gas annually. Over the last 24 months, natural gas prices have fluctuated between $5 and $12 per MMBtu, resulting in high and unpredictable fuel costs for the industrial sector. With abundant coal resources, an opportunity exists for the U.S. industrial ...

Dielectric structures driven by wakefields or external radio frequency (RF) are presently being studied intensively as a promising technique for next generation linear colliders. This project will develop dielectric loaded accelerating structures that can be adjusted in frequency using a bias electric field. The method proposed here is inexpensive and easy to implement without affecting beam quali ...

The single bunch beam breakup (BBU) instability is a potentially serious limitation on the performance of advanced accelerators, particularly those based on the wakefield principle. Development of mitigation techniques for BBU requires both experiment and high performance simulation tools. This project will study three representative high performance wakefield devices using new diagnostics. An adv ...
