Homeland Security: Progress Made; More Direction and Partnership Sought

Description: Testimony issued by the General Accounting Office with an abstract that begins "Enhancing homeland security is a complex effort that involves all 50 states, the District of Columbia, and the territories; thousands of municipalities; and countless private entities. Since September 11, the nation has taken many actions to combat terrorism and enhance homeland security. It is well known that the U.S. military is conducting operations in Afghanistan. Various legislative and executive branch actions… more

Workforce Investment Act: Coordination Between TANF Programs and One-Stop Centers Is Increasing, but Challenges Remain

Description: Testimony issued by the General Accounting Office with an abstract that begins "The Workforce Investment Act (WIA) brought most federally funded employment and training services into a single, one-stop center system. Coordination between Temporary Assistance for Needy Families (TANF) programs and one-stop centers has increased since the act was implemented in 2000. Nearly all states reported some coordination at either the state or the local level. Most often, coordination took one of two forms… more

Foreign Languages: Workforce Planning Could Help Address Staffing and Proficiency Shortfalls

Description: Testimony issued by the General Accounting Office with an abstract that begins "Federal agencies' foreign language needs have increased during the past decade because of increasing globalization and the changing security environment. At the same time, agencies have seen significant reductions-in-force and no-growth or limited-growth environments during the last decade. As a result, some agencies now confront an aging core of language-capable staff while recruiting and retaining qualified new st… more

Connecting to the Internet Securely: Windows 2000 CIAC-2321

Description: As the threat to computer systems increases with the increasing use of computers as a tool in daily business activities, the need to securely configure those systems becomes more important. There are far too many intruders with access to the Internet and the skills and time to spend compromising systems to not spend the time necessary to securely configure a system. Hand-in-hand with the increased need for security are an increased number of items that need to be securely configured. Windows 20… more

The Tevatron collider run 2 Prospects for discoveries in particle physics

Description: The chances of discovering the Standard Model Higgs boson in Run 2 at the Fermilab Tevatron Collider are discussed. The reach of a search for MSSM Higgs boson and for other Susy particles is also mentioned. The large integrated luminosity potentially offered by the upgraded Tevatron in the years before the start of LHC will make an exciting physics program possible in the next several years. Let aside the luminosity, we can rely now on two much more powerful detectors than in run 1. This is a v… more

Generalization of Spatial Channel Theory to Three-Dimensional x-y-z Transport Computations

Description: Spatial channel theory, initially introduced in 1977 by M. L. Williams and colleagues at ORNL, is a powerful tool for shield design optimization. It focuses on so called ''contributon'' flux and current of particles (a fraction of the total of neutrons, photons, etc.) which contribute directly or through their progeny to a pre-specified response, such as a detector reading, dose rate, reaction rate, etc., at certain locations of interest. Particles that do not contribute directly or indirectly … more

Determination and correction of the linear lattice of the APS storage ring.

Description: The authors have created precise linear models of the storage ring in terms of beta functions for both low-emittance and high-emittance lattices. Using these models, the beta function beating corrections have been successfully applied. The lifetime was increased by 40% for the low-emittance lattice as a result of the corrections. The models allow the user to apply predictable and precise changes to the existing lattice. For example, after applying the beta function corrections, the beta-functio… more

A time dependent fractional coverage model for the adsorption and removal of gas species and application to the friction behavior of superlow friction DLC.

Description: The frictional behavior of diamond-like carbon (DLC) films varies with environmental condition. One theory asserts that the cause of variations in the frictional performance is environmental contaminants adsorbing onto the DLC film surface. Testing of the frictional performance of DLC films in a pin-on-disk contact has mapped the transient behavior of the friction coefficient. A model for fractional coverage, based on the adsorption of environmental contaminants and their removal through the pi… more

Barrier Foil Heating Simulations Using LASNEX

Description: It is necessary to place a barrier foil in front of the X-ray converter target to prevent the backstreaming ions. This research note presents the simulations of foil heating using the latest EOS tables. LASNEX simulations are carried out using both DARHT-II and ETA-II beam parameters. Results for all the foils studied here, using the DARHT-II beam parameters, show that the integrated line density along the axis at the end of the 4th pulse remains essentially unchanged even if the foils are heat… more

Shocked and Stressed, Metals Get Stronger

Description: People who know their way around metalworking are no doubt familiar with peening--using a ball-peen hammer to pound a piece of metal into shape and strengthen it against fatigue failure. For the past 50 years, an industrialized equivalent has been shot peening, in which metal or ceramic beads as large as marbles or as small as salt and pepper grains pneumatically bombard a metal surface. Laser peening, a process based on a superior laser technology developed at Lawrence Livermore, replaces the … more

Evaluation of Absorbents for Compatibility with Site Generated Hazardous and Mixed Liquid Wastes

Description: SRS Solid Waste requested SRTC to perform a literature-based evaluation of sorbents, which are compatible with hazardous mixed waste being generated on site. Polypropylene-based materials and ground corn cob (Toxi-dry), because of their compatibility with the Consolidated Incinerator Facility (CIF) process, are the only two spill stabilization agents which are recommended for use on site (IS manual, Waste Acceptance Criteria 3.18). While ensuring minimal potential for undesired reactions betwee… more

The D0 detector at the Fermilab tevatron in run 2

Description: The D0 (DZERO) Detector at Fermilab has been collecting data since March 1, 2001. The detector has undergone an extensive upgrade to participate in the Run 2 data taking. The design of the detector meets the requirements of the high luminosity environment provided by the accelerator. This paper describes the upgraded detector subsystems and gives an outline of the physics potentials associated with the upgrade.

EMERGE. Final report

Description: EMERGE had two basic goals: (1) To ensure that the DOE-funded labs at UW-Madison, U of Chicago, and UIUC were connected to the DOE National Labs at the highest available speeds. EMERGE grantees were to work with DOE network engineers to achieve this goal. (2) Establish a testbed for DiffServ networking, develop monitoring, measuring and, visualization tools, develop a grid services package, cooperate with Internet2's Quality DiffServ efforts, and deploy results. For the most part these goals ha… more

The Effect of dead-timeless silicon strip readout at CDF II

Description: The Run IIa CDF Silicon Upgrade has recently finished installation. The detector uses revision D of the SVX3 readout IC. This final revision incorporated new features in order to improve the potential of dead-timeless operation. This paper describes measurements of dead-timeless effects on silicon strip readout on the test bench. This paper also describes tests of the dynamic pedestal subtraction circuitry, which is shown to improve greatly the dead-timeless performance of the silicon systems.
