A letter report issued by the General Accounting Office with an abstract that begins "Nonresponse follow-up was the most expensive and labor-intensive of all Census 2000 operations. The Census Bureau spent $1.2 billion and used more than 500,000 enumerators to obtain census information from 42 million nonresponding households in less than 10 weeks. Because of this colossal workload, even small variations in productivity had significant cost implications. Workload and enumerator productivity have historically been two of the largest drivers of census costs, and the Bureau developed its budget model for the 2000 Census using key assumptions about these two variables. Nationally, enumerators completed their nonresponse follow-up workload at a rate of 1.04 housing units per hour--slightly exceeding the Bureau's expected rate of 1.03 housing units per hour. Productivity varied for the four primary types of local census offices, ranging from 0.90 housing units per hour in inner-city and urban areas to 1.10 cases per hour in rural areas. In refining the data, the Bureau corrected what it considered to be the most significant discrepancy--a misclassification of some employees' time charges that overstated the number of hours worked by nonresponse follow-up enumerators and understated enumerator production rates."

This report provides statistical information and possible solutions to the multilateral and bilateral debt of Africa. Possible solutions include debt forgiveness options, yet this comes with the consequence of limited future aid from multilateral agencies.

The final goal behind any numerical method is give the smallest wall-clock time for a given final time error or, conversely, the smallest run-time error for a given wall clock time, etc. Here a comparison will be given between adaptive mesh refinement schemes and non-adaptive schemes of higher order. It will be shown that in three dimension calculations that in order for AMR schemes to be competitive that the finest scale must be restricted to an extremely, and unrealistic, small percentage of the computational domain.

A chapter report issued by the Government Accountability Office with an abstract that begins "Amtrak has struggled since its inception to earn sufficient revenues and operate efficiently. In June 2002, Amtrak's new president began major efforts to improve efficiency. However, the financial condition of the company remains precarious, requiring a federal subsidy of more than $1 billion annually. Capital backlogs are now about $6 billion, with over 60 percent being attributable to its mainstay Northeast Corridor service. GAO reviewed Amtrak's (1) strategic planning, (2) financial reporting and financial management practices, (3) cost containment strategies, (4) acquisition management, and (5) accountability and oversight."

This analysis report describes the methods used to determine hydrologic properties based on the available field data from the unsaturated zone (UZ) at Yucca Mountain, Nevada. The technical scope, content, and management of this analysis report are described in the planning document ''Technical Work Plan for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654], Sections 2, 4, and 8). Fracture and matrix properties are developed by analyzing available survey data from the Exploratory Studies Facility (ESF), the Enhanced Characterization of Repository Block (ECRB) Cross-Drift, and/or boreholes; air-injection testing data from surface boreholes and from boreholes in the ESF; and data from laboratory testing of core samples. In addition, the report ''Geologic Framework Model'' (GFM2000) (BSC 2004 [DIRS 170029]) also serves as a source report by providing the geological framework model of the site. This report is a revision of the model report under the same title (BSC 2003 [DIRS 161773]), which in turn superceded the analysis report under the same title. The principal purpose of this work is to provide representative uncalibrated estimates of fracture and matrix properties for use in the model report Calibrated Properties Model. The term ''uncalibrated'' is used to distinguish the properties …

The Adaptive Optics (AO) Group in I Division develops and tests a broad range of advanced wavefront control technologies. Current applications focus on: Remote sensing, High power lasers, Astronomy, and Human vision. In the area of remote sensing, the AO Group leads a collaborative effort with LLNL's Nonproliferation, Arms Control & International Security (NAI) Directorate on Enhanced Surveillance Imaging. The ability to detect and identify individual people or vehicles from long-range is an important requirement for proliferation detection and homeland security. High-resolution imaging along horizontal paths through the atmosphere is limited by turbulence, which blurs and distorts the image. For ranges over {approx}one km, visible image resolution can be reduced by over an order of magnitude. We have developed an approach based on speckle imaging that can correct the turbulence-induced blurring and provide high resolution imagery. The system records a series of short exposure images which freeze the atmospheric effects. We can then estimate the image magnitude and phase using a bispectral estimation algorithm which cancels the atmospheric effects while maintaining object information at the diffraction limit of the imaging system.

An ARAMS/FRAMES utility entitled ''Joint Frequency Data (JFD) Generator'' provides the capability of creating joint frequency tables. The resultant JFD tables contain summaries of the frequency of occurrence of meteorological dispersion, wind speed, and wind direction that are required as input in climatological air dispersion models. The JFD Generator computations are made by an updated version of the EPA STAR (STAbility ARray) program. Surface observations are combined with computed seasonally and diurnally varying solar flux rates to estimate the ambient atmospheric dispersion rates, represented as a stability category. The wind speeds and directions are obtained directly from the hourly surface observation data. The product is a file in a format that can be directly read by an air dispersion model. The JFD Generator can input hourly meteorological surface observation data in CD-144, Samson, and SCRAM data formats. An enhanced joint frequency table file that can be read directly by the ARAMS/FRAMES interface is produced. The output file has a format can be used by the MEPAS air dispersion program or can be modified for input to other models requiring joint frequency input.

Reflectometry, which uses the microwave radar technique to probe the magnetically confined fusion plasmas, is a very powerful tool to observe the density fluctuations in the fusion plasmas. Typically, two or more microwave beams of different frequencies are used to study the plasma density fluctuations. The frequency separation between these two beams of the PPPL designed reflectometer system upgrade on the DIII-D tokamak can be varied over 18 GHz. Due to the performance of the associated electronics, the local oscillator (LO) power level at the LO port of the I/Q demodulator suffers more than 12 dB of power fluctuations when the frequency separation is varied. Thus, the I/Q demodulator performance is impaired. In order to correct this problem, a power leveling circuit is introduced in the PPPL upgrade. According to the test results, the LO power fluctuation was regulated to be within 1 dB for greater than 16 dB of input power variation over the full dynamic bandwidth of the receiver.

Raising the share of income we save is a frequent aim of public policy. That may be particularly apparent in debates about the size of the federal budget deficit, but concerns about the low household saving rate have also prompted policymakers to consider ways to encourage individuals to save more. How much individuals save will directly affect their future economic well-being, but from a macroeconomic perspective, the source of saving — be it households, business, or government — makes no difference. This report presents standard economic analysis of the macroeconomic effects of raising saving.

The September 11, 2001 terrorist attack on the World Trade Center and the Pentagon led to the closing the following day of 50 of the nearly 260 U.S. embassies and consulates worldwide. A week later, however, all U.S. facilities were open for business. Additionally, three embassies – in Pakistan, Yemen, and Turkmenistan – allowed for voluntary evacuations immediately after the attack. In the months prior to the attack, travel warnings were issued and embassies were put on high alert as Osama bin Laden had issued vague, but credible, threats against Americans and American interests around the world.

The Emergency Alert System (EAS) is built on a structure conceived in the 1950s when over-the-air broadcasting was the best-available technology for widely disseminating emergency alerts. Bills in the 109th Congress that would improve emergency alert systems, domestically and internationally, include S. 50 (Senator Inouye) and H.R. 296 (Representative Menendez); these bills were prompted by the tsunami disaster but include measures that also apply to the need for a better all-hazard warning system in the United States. The report summarizes the technology and administration of EAS and the National Oceanic and Atmospheric Administration (NOAA)/National Weather Service (NWS) all-hazard network, new programs in the Department of Homeland Security (DHS), and some of the key proposals for change.

The Emergency Alert System (EAS) is one of several federally managed warning systems.
