2010 Census: Data Collection Operations Were Generally Completed as Planned, but Long-standing Challenges Suggest Need for Fundamental Reforms

Description: 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 se… more

2010 Census: Follow-up Should Reduce Coverage Errors, but Effects on Demographic Groups Need to Be Determined

Description: 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 (F… more

2010 Census: Key Efforts to Include Hard-to-Count Populations Went Generally as Planned; Improvements Could Make the Efforts More Effective for Next Census

Description: 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… more

2D Spatial Frequency Considerations in Comparing 1D Power Spectral Density Measurements

Description: 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… more

3D Thermal and Electrochemical Model for Spirally Wound Large Format Lithium-ion Batteries

Description: 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, ca… more

Access to Broadband Networks: The Net Neutrality Debate

Description: 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

Description: 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.

Air Force KC-X Tanker Aircraft Program: Background and Issues for Congress

Description: This report discusses the issues for Congress in FY2011, which are whether to approve, reject, or modify DOD's new KC-X competition strategy, and whether to approve, reject, or modify the Air Force's request for FY2011 research and development funding for the new KC-X program. Congress' decision on these issues could affect DOD capabilities and funding requirements, and the aircraft manufacturing industrial base.

Algorithm for Computation of Electromagnetic Fields of An Accelerated Short Bunch Inside a Rectangular Chamber

Description: 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 charge… more

Application for a Permit to Operate a Class III Solid Waste Disposal Site at the Nevada Test Site Area 5 Asbestiform Low-Level Solid Waste Disposal Site

Description: The NTS solid waste disposal sites must be permitted by the state of Nevada Solid Waste Management Authority (SWMA). The SWMA for the NTS is the Nevada Division of Environmental Protection, Bureau of Federal Facilities (NDEP/BFF). The U.S. Department of Energy's National Nuclear Security Administration Nevada Site Office (NNSA/NSO) as land manager (owner), and National Security Technologies (NSTec), as operator, will store, collect, process, and dispose all solid waste by means that do not crea… more

APPLICATION OF A THIN FILM EVAPORATOR SYSTEM FOR MANAGEMENT OF LIQUID HIGH-LEVEL WASTES AT HANFORD

Description: A modular, transportable evaporator system, using thin film evaporative technology, is planned for deployment at the Hanford radioactive waste storage tank complex. This technology, herein referred to as a wiped film evaporator (WFE), will be located at grade level above an underground storage tank to receive pumped liquids, concentrate the liquid stream from 1.1 specific gravity to approximately 1.4 and then return the concentrated solution back into the tank. Water is removed by evaporation a… more

Beam Conditioning for Free Electron Lasers:Consequences and Methods

Description: The consequences of beam conditioning in four example cases [VISA, a soft x-ray free-electron laser (FEL), LCLS, and a 'Greenfield' FEL] are examined. It is shown that in emittance limited cases, proper conditioning reduces sensitivity to the transverse emittance and, furthermore, allows for stronger focusing in the undulator. Simulations show higher saturation power, with gain lengths reduced by a factor of 2 or more. The beam dynamics in a general conditioning system are studied, with 'matchi… more

Benzene-derived N2-(4-hydroxyphenyl)-deoxyguanosine adduct: UvrABC incision and its conformation in DNA

Description: Benzene, a ubiquitous human carcinogen, forms DNA adducts through its metabolites such as p-benzoquinone (p-BQ) and hydroquinone (HQ). N(2)-(4-Hydroxyphenyl)-2'-deoxyguanosine (N(2)-4-HOPh-dG) is the principal adduct identified in vivo by (32)P-postlabeling in cells or animals treated with p-BQ or HQ. To study its effect on repair specificity and replication fidelity, we recently synthesized defined oligonucleotides containing a site-specific adduct using phosphoramidite chemistry. We here repo… more

Briefing on Commercial and Department of Defense Space System Requirements and Acquisition Practices

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has had long-standing difficulties developing and delivering space systems on time and within budget. Some programs have been delayed by years and cost billions of dollars more than their initial estimates. Attempts to reform DOD space acquisitions in the past have sought to leverage commercial approaches or rely more on the commercial sector to meet DOD needs. These effor… more
