Nuclear Waste Cleanup: DOE Has Made Some Progress in Cleaning Up the Paducah Site, but Challenges Remain
A letter report issued by the General Accounting Office with an abstract that begins "In 1988, radioactive contamination was found in the drinking water wells of residences near the federal government's uranium enrichment plant in Paducah, Kentucky. In response, the Department of Energy (DOE) began a cleanup program. In 2000, GAO reported that DOE faced significant challenges in cleaning up the site and that it was doubtful that the cleanup would be completed as scheduled by 2010 and within the $1.3 billion cost projection. GAO was asked to determine (1) the amount of money DOE has spent on the site, the purposes for which it was spent, and the estimated total costs for the site; (2) the status of DOE cleanup efforts; and (3) the challenges GAO previously identified that continue to be issues for DOE."

Chemical Weapons: Destruction Schedule Delays and Cost Growth Continue to Challenge Program Management
Testimony issued by the General Accounting Office with an abstract that begins "Since its inception in 1985, the Chemical Demilitarization (Chem-Demil) Program has been charged with destroying the nation's large chemical weapons stockpile of over 31,000 tons of agent. The program started destroying the stockpile in 1990. As of March 2004, the program had destroyed over 27 percent of the stockpile. The program has recently reorganized into the Chemical Materials Agency (CMA) to manage seven of the nine sites. There are five sites using incineration to destroy the agent and two bulk agent only sites using neutralization. The Assembled Chemical Weapons Alternatives (ACWA) Program, in the Department of Defense (DOD), manages two sites using neutralization to destroy agent in weapons. This testimony updates GAO's September 2003 report and October 2003 testimony. As requested, it focuses on the following issues: (1) changes in the status of schedule milestones and costs at the sites, (2) recent developments that impact the Chemical Weapons Convention (CWC) deadlines, (3) the challenges associated with managing the program, and (4) an update on the status of the Chemical Stockpile Emergency Preparedness Program (CSEPP)."

U.S. International Broadcasting: Challenges Facing the Broadcasting Board of Governors
Testimony issued by the General Accounting Office with an abstract that begins "The terrorist attacks of September 11, 2001, were a dramatic reminder of the importance of cultivating a better understanding of the United States and our policies with overseas audiences. U.S. public diplomacy activities include the efforts of the Broadcasting Board of Governors, which oversees all nonmilitary U.S. international broadcasting by the Voice of America (VOA) and several other broadcast entities. Such broadcasting helps promote a better understanding of the United States and serves U.S. interests by providing overseas audiences with accurate and objective news about the United States and the world. GAO has issued three reports over the past 4 years examining the organizational, marketing, resource, and performance reporting challenges faced by the Board. Our recommendations to the Board have included the need to address the long-standing issue of overlapping language services (that is, where two services broadcast in the same language to the same audience) and to strengthen the Board's strategic planning and performance by placing a greater emphasis on results. The Board has taken significant steps to respond to these and other recommendations."

Dimensional errors in LIGA-produced metal structures due to thermal expansion and swelling of PMMA.
Numerical methods are used to examine dimensional errors in metal structures microfabricated by the LIGA process. These errors result from elastic displacements of the PMMA mold during electrodeposition and arise from thermal expansion of the PMMA when electroforming is performed at elevated temperatures and from PMMA swelling due to absorption of water from aqueous electrolytes. Both numerical solutions and simple analytical approximations describing PMMA displacements for idealized linear and axisymmetric geometries are presented and discussed. We find that such displacements result in tapered metal structures having sidewall slopes up to 14 {micro}m per millimeter of height for linear structures bounded by large areas of PMMA. Tapers for curved structures are of similar magnitude, but these structures are additionally skewed from the vertical. Potential remedies for reducing dimensional errors are also discussed. Here we find that auxiliary moat-like features patterned into the PMMA surrounding mold cavities can reduce taper by an order of magnitude or more. Such moats dramatically reduce tapers for all structures, but increase skew for curved structures when the radius of curvature is comparable to the structure height.

Large batch dimensional metrology demonstrated in the example of a LIGA fabricated spring.
Deep x-ray lithography in combination with electroforming is capable of producing high precision metal parts in small lot series. This study deals with a high aspect ratio structure with overall dimensions on the order of 10 mm x 7 mm x 1.5 mm, with the smallest line width being 150 {micro}m. The lateral deviation from the design is to be kept to a minimum, preferably below 5 {micro}m. To ensure adequate quality control, a semi-automated metrology technique has been established to measure all parts. While the paper will give a brief overview of all involved techniques, it focuses on the method to measure the top and bottom of the parts and the top of geometries following the process. The instrument used is a View Engineering Voyager V6x12 microscope, which is fully programmable. The microscope allows direct measurement of geometries but also is capable of saving all captured data as point clouds. These point clouds play a central role when evaluating part geometry. After measuring the part, the point cloud is compared to the computer aided design (CAD) contour of the part, using a commercially available software package. The challenge of proper edge lighting on a nickel alloy part is evaluated …

X-Ray Line Measurements with High Efficiency Bragg Crystals
We have studied the focusing properties of two highly oriented pyrolitic graphite (HOPG) spectrometers, which differ in the degree of the mosaic spread: ZYA with a low mosaic spread ({gamma}=0.4 degrees) and ZYH with a large mosaic spread ({gamma}=3.5 degrees). In order to assess the crystal performance for a variety of different experiments, various K{alpha} and K{beta} x-ray lines have been produced using a high-intensity ({approx}>10{sup 17} W/cm{sup 2}) short-pulse ({approx} 100 fs) laser beam focused onto Ti, V, Zn, and Cu foils. The measured spectral resolution of the HOPG crystals in both first and second order diffraction has been compared with theoretical predictions. Using known values for the peak reflectivity of HOPG crystals, we have also computed K{alpha} x-ray conversion efficiencies of Ti, V, Zn, and Cu. These results are important to estimate the optimal conditions under which different types of HOPG monochromators can be used for the detection of weak x-ray signals as the one encountered in x-ray Thomson/Compton scattering experiments.

The Production Cross Sections of the Weak Vector Bosons in Proton Antiproton Collisions at s**(1/2) = 1.96-TeV and a Measurement of the W Boson Decay Width
The theory that describes the fundamental particle interactions is called the Standard Model, which is a gauge field theory that comprises the Glashow-Weinberg-Salam model [1, 2, 3] of the weak and electromagnetic interactions and quantum chromodynamics (QCD) [4, 5, 6], the theory of the strong interactions. The discovery of the W [7, 8] and Z [9, 10] bosons in 1983 by the UA1 and UA2 collaborations at the CERN p{bar p} collider provided a direct confirmation of the unification of the weak and electromagnetic interactions. Since then, many experiments have refined our understanding of the characteristics of the W and Z bosons.

Implementation of Frictional Contact Conditions in Surface to Surface, Mortar Based Computational Frameworks
A number of recent works have established the mortar technique as an accurate and robust spatial discretization method for contact problems in computational solid mechanics. Since methods based on this idea rely on an integral, non-local representation of the contact operators, their formulation is somewhat more involved than is true for more traditional ''point to surface'' contact algorithms; in particular, the integral projections have nontrivial linearizations in the fully large deformation context. In this work, we concentrate on another aspect of formulations of this type--definition and implementation of frictional contact operators within the mortar contact framework. Issues associated with frame indifference of frictional tractions and kinematics are discussed, and a numerical demonstration of the technique is given.

A 3D Frictional Segment-to-Segment Contact Method for Large Deformations and Quadratic Elements
Node-on-segment contact is the most common form of contact used today but has many deficiencies ranging from potential locking to non-smooth behavior with large sliding. Furthermore, node-on-segment approaches are not at all applicable to higher order discretizations (e.g. quadratic elements). In a previous work, [3, 4] we developed a segment-to-segment contact approach for eight node hexahedral elements based on the mortar method that was applicable to large deformation mechanics. The approach proved extremely robust since it eliminated the over-constraint that caused 'locking' and provided smooth force variations in large sliding. Here, we extend this previous approach to treat frictional contact problems. In addition, the method is extended to 3D quadratic tetrahedrals and hexahedrals. The proposed approach is then applied to several challenging frictional contact problems that demonstrate its effectiveness.
