805 MHz and 201 MHz RF cavity development for MUCOOL

Description: A muon cooling channel calls for very high acceleratinggradient RF structures to restore the energy lost by muons in theabsorbers. The RF structures have to be operated in a strong magneticfield and thus the use of superconducting RF cavities is excluded. Toachieve a high shunt impedance while maintaining a large enough apertureto accommodate a large transverse emittance muon beam, the cavity designadopted is a pillbox-like geometry with thin Be foils to terminate theelectromagnetic field at th… more

1999 Summer Research Program for High School Juniors at the University of Rochester's Laboratory for Laser Energetics

Description: oak-B202--During the summer of 1999, 12 students from Rochester-area high schools participated in the Laboratory for Laser Energetics' Summer High School Research Program. The goal of this program is to excite a group of high school students about careers in the areas of science and technology by exposing them to research in a state-of-the-art environment. Too often, students are exposed to ''research'' only through classroom laboratories that have prescribed procedures and predictable results.… more

2000 Census: Complete Costs of Coverage Evaluation Programs Are Not Available

Description: A letter report issued by the General Accounting Office with an abstract that begins "To assess the quality of the population data collected in the 2000 Census, the U.S. Census Bureau conducted the Accuracy and Coverage Evaluation (A.C.E.) program, which focused on a survey of housing units designed to estimate the number of people missed, counted more than once, or otherwise improperly counted in the census. GAO reviewed the life cycle costs of the A.C.E. program and its predecessor, the Integ… more

2000 Census: Lessons Learned for Planning a More Cost-Effective 2010 Census

Description: A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the funding of 2000 Census planning and development efforts and the impact it had on census operations. Total funding for the 2000 Census, referred to as the life cycle cost, covers a 13-year period from fiscal year 1991 through fiscal year 2003 and is expected to total $6.5 billion adjusted to 2000 year dollars. This amount was almost double the reported life cycle cost of the 1990 Census of $3.3… more

Acoustic Monitor for Liquid-Solid Slurries Measurements at Low Weight Fractions

Description: The principal objective of the project is to develop an acoustic probe for determining the weight fraction of particles in a flowing suspension. The suspension can be solid-liquid (S-L) or solid-gas-liquid (S-G-L). The work will include testing the theory of acoustic wave propagation in suspensions and demonstrating the application of the probe by installing it on a flow loop through which a suspension is flowing and determining the particle weight fraction. The signal from the probe must be pr… more

Active flow control for maximizing performance of spark ignited stratified charge engines. Final report

Description: Reducing the cycle-to-cycle variability present in stratified-charge engines is an important step in the process of increasing their efficiency. As a result of this cycle-to-cycle variability, fuel injection systems are calibrated to inject more fuel than necessary, in an attempt to ensure that the engines fire on every cycle. When the cycle-to-cycle variability is lowered, the variation of work per cycle is reduced and the lean operating limit decreases, resulting in increased fuel economy. In… more

Adaptive dimension reduction for clustering high dimensional data

Description: It is well-known that for high dimensional data clustering, standard algorithms such as EM and the K-means are often trapped in local minimum. many initialization methods were proposed to tackle this problem, but with only limited success. In this paper they propose a new approach to resolve this problem by repeated dimension reductions such that K-means or EM are performed only in very low dimensions. Cluster membership is utilized as a bridge between the reduced dimensional sub-space and the … more

ADVANCED GASIFICATION-BASED FUEL CONVERSION AND ELECTRIC ENERGY PRODUCTION SYSTEM

Description: Boise Paper Solutions and the Gas Technology Institute (GTI) are cooperating to develop, demonstrate and place in continuous operation an advanced biomass gasification-based power generation system suitable for near-term commercial deployment in the Forest Products Industry. The system will be used in conjunction with, rather than in place of, existing wood waste fired boilers and flue gas cleanup systems. The novel system will include three advanced technological components based on GTI's RENU… more

Advanced Stripper Gas Produced Water Remediation, Quarterly Technical Report: July-September 2002

Description: Natural gas and oil production from stripper wells also produces water contaminated with hydrocarbons, and in most locations, salts and trace elements. The hydrocarbons are not generally present in concentrations that allow the operator to economically recover these liquids. Produced liquids, (Stripper Gas Water) which are predominantly water, present the operator with two options; purify the water to acceptable levels of contaminates, or pay for the disposal of the water. The project scope inv… more

Advanced Tokamak Operation Using the DIII-D Plasma Control System

Description: A271 ADVANCED TOKAMAK OPERATION USING THE DIII-D PLASMA CONTROL SYSTEM. The principal focus of experimental operations in the DIII-D tokamak is the advanced tokamak (AT) regime to achieve, which requires highly integrated and flexible plasma control. In a high performance advanced tokamak, accurate regulation of the plasma boundary, internal profiles, pumping, fueling, and heating must be well coordinated with MHD control action to stabilize such instabilities as tearing modes and resistive wal… more

Aerial Image Microscopes for the Inspection of Defects in EUV Masks

Description: The high volume inspection equipment currently available to support development of EUV blanks is non-actinic. The same is anticipated for patterned EUV mask inspection. Once potential defects are identified and located by such non-actinic inspection techniques, it is essential to have instrumentation to perform detailed characterization, and if repairs are performed, re-evaluation. The ultimate metric for the acceptance or rejection of a mask due to a defect, is the wafer level impact. Thus mea… more

Afghanistan: Current Issues and U.S. Policy

Description: The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and… more

Agriculture: U.S.-China Trade Issues

Description: With China’s entry into the World Trade Organization (WTO) in December 2001, U.S. agricultural interests were hopeful that longstanding barriers to trade with that vast and growing market would begin to fall. However, critics charge that China is failing to honor commitments to open its markets, affecting U.S. exports of grains, oilseeds, meat and poultry, and other products. U.S. agriculture and trade officials have been working to resolve these differences.
