2009 Annual Health Physics Report for the HEU Transparency Program
During the 2009 calendar year, Lawrence Livermore National Laboratory (LLNL) provided health physics support for the Highly Enriched Uranium (HEU) Transparency Program for external and internal radiation protection. LLNL also provided technical expertise related to BDMS radioactive sources and Russian radiation safety regulatory compliance. For the calendar year 2009, there were 159 person-trips that required dose monitoring of the U.S. monitors. Of the 159 person-trips, 149 person-trips were SMVs and 10 person-trips were Transparency Monitoring Office (TMO) trips. There were 4 monitoring visits by TMO monitors to facilities other than UEIE and 10 to UEIE itself. LLNL's Hazard Control Department laboratories provided the dosimetry services for the HEU Transparency monitors. In 2009, the HEU Transparency activities in Russia were conducted in a radiologically safe manner for the HEU Transparency monitors in accordance with the expectations of the HEU Transparency staff, NNSA and DOE. The HEU Transparency Program now has over fifteen years of successful experience in developing and providing health and safety support in meeting its technical objectives.

2010 Census: Data Collection Operations Were Generally Completed as Planned, but Long-standing Challenges Suggest Need for Fundamental Reforms
A letter report issued by the Government Accountability Office with an abstract that begins "Although the U.S. Census Bureau (Bureau) generally completed the field data collection phase of the 2010 Census consistent with its operational plans, at $13 billion, 2010 was the costliest census in the nation's history. Moving forward, it will be important to both refine existing operations as well as to reexamine the fundamental approach to the census to better address long-standing issues such as securing participation and escalating costs. As requested, this report reviews (1) the conduct of nonresponse follow-up (NRFU), where enumerators collect data from households that did not return their census forms, (2) the implementation of other field operations critical to a complete count, and (3) potential reexamination areas that could help produce a more cost-effective 2020 Census. The report is based on GAO's analysis of Bureau data and documents, surveys of local census office managers, and field observations."

2010 Census: Follow-up Should Reduce Coverage Errors, but Effects on Demographic Groups Need to Be Determined
A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Census Bureau (Bureau) puts forth tremendous effort to conduct a complete and accurate count of the nation's population and housing; yet some degree of error in the form of persons missed, duplicated, or counted in the wrong place is inevitable due to the complexity in counting a large and diverse population. The Bureau designed two operations, Coverage Follow-up (CFU) and Field Verification (FV), to reduce certain types of counting, or coverage, errors in the 2010 Census. GAO was asked to assess (1) the extent to which the Bureau completed CFU and FV on schedule and within estimated cost and (2) the implications of their key design elements for improving coverage. GAO reviewed Bureau evaluations, planning, and other documents on CFU and FV, and prior GAO work, and interviewed Bureau officials."

2010 Census: Key Efforts to Include Hard-to-Count Populations Went Generally as Planned; Improvements Could Make the Efforts More Effective for Next Census
A letter report issued by the Government Accountability Office with an abstract that begins "To overcome the long-standing challenge of enumerating hard-to-count (HTC) groups such as minorities and renters, the U.S. Census Bureau (Bureau), used outreach programs, such as paid advertising, and partnered with thousands of organizations to enlist their support for the census. The Bureau also conducted Service-Based Enumeration (SBE), which was designed to count people who frequent soup kitchens or other service providers, and the Be Counted/Questionnaire Assistance Center (QAC) program, designed to count individuals who believed the census had missed them. As requested, GAO assessed how the design of these efforts compared to 2000 and the extent to which they were implemented as planned. GAO reviewed Bureau budget, planning, operational, and evaluation documents; observed enumeration efforts in 12 HTC areas; surveyed local census office managers; and interviewed Bureau officials."

2D Spatial Frequency Considerations in Comparing 1D Power Spectral Density Measurements
The frequency footprint of ID and 2D profiling instruments needs to be carefully considered in comparing ID surface roughness spectrum measurements made by different instruments. Contributions from orthogonal direction frequency components can not be neglected. The use of optical profiling instruments is ubiquitous in the measurement of the roughness of optical surfaces. Their ease-of-use and non-contact measurement method found widespread use in the optics industry for measuring the quality of delicate optical surfaces. Computerized digital data acquisition with these instruments allowed for quick and easy calculation of surface roughness statistics, such as root-mean-square (RMS) roughness. The computing power of the desktop computer allowed for the rapid conversion of spatial domain data into the frequency domain, enabling the application of sophisticated signal processing techniques to be applied to the analysis of surface roughness, the most powerful of which is the power spectral density (PSP) function. Application of the PSD function to surface statistics introduced the concept of 'bandwidth-limited' roughness, where the value of the RMS roughness depends critically upon the spatial frequency response of the instrument. Different instruments with different spatial frequency response characteristics give different answers when measuring the same surface.

3D Thermal and Electrochemical Model for Spirally Wound Large Format Lithium-ion Batteries
In many commercial cells, long tabs at both cell sides, leading to uniform potentials along the spiral direction of wound jelly rolls, are rarely seen because of their high manufacturing cost. More often, several metal strips are welded at discrete locations along both current collector foils. With this design, the difference of electrical potentials is easily built up along current collectors in the spiral direction. Hence, the design features of the tabs, such as number, location and size, can be crucial factors for spiral-shaped battery cells. This paper presents a Li-ion battery cell model having a 3-dimensional spiral mesh involving a wound jellyroll structure. Further results and analysis will be given regarding impacts of tab location, number, and size.

Access to Broadband Networks: The Net Neutrality Debate
This report discusses the current debate over "net neutrality." While there is no single accepted definition of "net neutrality," most agree that any such definition should include the general principles that owners of the networks that compose and provide access to the Internet should not control how consumers lawfully use that network, and they should not be able to discriminate against content provider access to that network.

Afghanistan Development: Enhancements to Performance Management and Evaluation Efforts Could Improve USAID's Agricultural Programs
A letter report issued by the Government Accountability Office with an abstract that begins "Eighty percent of Afghans are dependent on agriculture for their livelihoods. Agricultural assistance is a key U.S. contribution to Afghanistan's reconstruction efforts. Since 2002, the U.S. Agency for International Development (USAID) has awarded about $1.4 billion for agricultural programs to increase agricultural productivity, accelerate economic growth, and eliminate illicit drug cultivation. This report (1) describes the change in U.S. focus on agricultural assistance since 2002, (2) assesses USAID's performance management and evaluation of its agricultural programs, (3) analyzes the extent to which certain programs met targets, and (4) addresses efforts to mitigate implementation challenges. GAO reviewed USAID documents; analyzed program data; and interviewed program implementers and USAID officials in Washington, D.C., and Afghanistan. GAO has prepared this report as part of its ongoing efforts to monitor key aspects of U.S. efforts in Afghanistan."

Algorithm for Computation of Electromagnetic Fields of An Accelerated Short Bunch Inside a Rectangular Chamber
We discuss the feasibility of an application of an implicit finite-difference approximation to calculate the fields of a relativistic bunch moving with no restriction inside a vacuum chamber. We assume that a bunch trajectory is not straight but is inside a vacuum chamber or its branch. The bunch can be deflected by the fields of bending magnets. The bunch can be short enough to produce coherent synchrotron radiation (CSR). Accelerator physicists believe that electromagnetic phenomena of charged beams are governed by Maxwell's equations together with Newton's equations for particle dynamics. To understand the behavior of the beams and radiated fields we just need to find a solution to these equations for the case, which can fully describe the real accelerator environment. So, at first we make a model, which contains all the necessary components, but at the same time can be easily 'inserts' into the equations. Sometimes, it is possible to find analytical solutions, but usually they are only work for one-dimensional cases and rarer for two-dimension cases. To find a solution in general we may transform the equations into a equivalent finite-difference form and solve them using computers. We can find a lot of finite-difference schemes, which approximate Maxwell's …
