Considerations of bunch-spacing options for multi-bunch operation of the Tevatron Collider

This discussion will consider a number of points relevant to limitations, advantages and disadvantages of various arrangements of bunches in the Tevatron proton-antiproton collider. The considerations discussed here will be limited to: (a) bunch spacing symmetry and relation to the relative luminosity at B0 and D0 and the beam-beam interaction with separated beams; (b) bunch spacing constraints imposed by Main Ring RF coalescing and the optics of beam separation at B0 and D0; and (c) bunch spacing constraints imposed by injection and abort kicker timing requirements, and by the Antiproton Source RF unstacking process. 20 figs., 17 tabs.

An Integral Design Technique for Wideband Multistage Transistor Amplifiers (open access)

An Integral Design Technique for Wideband Multistage Transistor Amplifiers

A philosophy for designing wideband multistage transistor amplifiers is presented. The amplifier was visualized as an integral unit, the interstage networks constituting the elements of the amplifier unit. By designing the amplifier as a unit and adjusting the over-all response (gain and bandwidth) with the interstage time constants, an increase in gain-bandwidth product was realized over the iteratively designed amplifiers. The resulting increase in gainbandwidth product resulted from absence of the bandwidth shrinkage factor for multistage amplifiers. Formulas were derived for both a two- and three- transistor integrally designed wideband amplifier, in which shunt peaking networks were used for coupling. Experimental amplifiers were con structcd following these formulas, and the observed performance agreed quite well with the calculations. (auth)

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."

Quality of Life for U.S. Soldiers Deployed in the Balkans

Correspondence issued by the General Accounting Office with an abstract that begins "U.S. Army ground forces have been deployed to the Balkans since December 1995. For these personnel, such a tour of duty involves a significant change in living conditions and separation from family and friends. The Army has spent more than $2 billion to build camps and implement services to sustain deployed personnel. Much of what has been spent contributes to enhancing soldiers' quality of life. GAO examined (1) how the Army defines and views the quality of life of deployed soldiers in the Balkans and (2) the quality of life at three base camps in Bosnia, Kosovo, and Macedonia. GAO found that the Army (1) defines quality of life as the provision of equitable, adequate, and appropriate living, working, and leisure conditions consistent with available resources and political and military considerations and (2) is providing facilities in keeping with its established quality of life standards. GAO also found that most soldiers were satisfied with the living conditions and recreational facilities."

DOD Travel Improper Payments: Fiscal Year 2006 Reporting Was Incomplete and Planned Improvement Efforts Face Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "Fiscal year 2006 was the first year that the Department of Defense (DOD) reported improper payment information for its travel program under the Improper Payments Information Act of 2002 (IPIA). For fiscal year 2006, DOD reported obligations of approximately $8.5 billion for travel. Congress mandated that GAO assess the reasons why DOD is not fully in compliance with IPIA related to travel expenditures. In May 2007, GAO issued an initial report in response to this mandate. To further respond, GAO assessed (1) the completeness and accuracy of DOD's fiscal year 2006 IPIA travel disclosure in its performance and accountability report (PAR), and (2) DOD's planned efforts to improve and refine its processes for estimating and reporting on travel improper payments. To complete this work, GAO reviewed DOD's IPIA reporting, IPIA, Office of Management and Budget's (OMB) IPIA implementing guidance, and met with cognizant DOD officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice's (DOJ) three grant-making components--the Office of Justice Programs (OJP), the Office of Community Oriented Policing Services (COPS), and the Office on Violence Against Women (OVW)--have partially met five of six leading practices, and fully met another, to ensure that the staffing models the contractor prepared for each of them to assess their workloads and workforce capacities are sound and reliable. These six leading practices are broad areas that represent a summary of the activities that should take place during the three stages of model design, development, and deployment. For example, the components partially met the leading practice for ensuring the credibility of data used in the models. This practice includes both verifying with staff that the models accurately depict the component's operations--an activity in which they fully engaged--and testing the models for logic and accuracy--an activity in which they partially engaged. Specifically, the components did not comprehensively check all of the models' formulas, and GAO found errors with all three components' models' retirement calculations. When left uncorrected, such errors have implications for workforce-related decisions and, ultimately, can affect the efficiency and effectiveness …

Earned Income Tax Credit Eligibility and Participation

Correspondence issued by the General Accounting Office with an abstract that begins "The Earned Income Tax Credit (EIC), which is expected to provide more than $20 billion in refundable tax credits in fiscal year 2002, is intended to offset the burden of the Social Security payroll tax on low-income workers and encourage low-income individuals to work. About 75 percent of the 17.2 million eligible households have claimed the credit. GAO found that the participation rate varied by the number of qualifying children in the household. Participation rates for households with one or two qualifying children were 96 percent and 93 percent respectively. In contrast, the participation rate for households with three or more qualifying children was 62.5 percent. The participation rate for households with no qualifying children was 44.7 percent. Although qualifying households were eligible to claim $22.3 billion in EICs in 1999, the Internal Revenue Service estimates that participating households actually claimed $20.9 billion."
