In March, CBO released its report analyzing the President’s policies. CBO’s estimates of the President’s budget, a recasting of the policies using CBO assumptions and budget estimating methods, raise the expected deficit for FY2004 to $338 billion from the OMB estimated $307 billion. The report also included an update to CBO’s January baseline that pushed the deficit for FY2004 to $200 billion from $145 billion. The revisions delay the return-to-a-surplus from FY2007 to FY2008 and reduce the cumulative FY2004-FY2013 surplus from $1,336 billion (January) to $891 billion (March).

A letter report issued by the General Accounting Office with an abstract that begins "Since 1996, federal land management agencies have collected over $900 million in recreation fees from the public under an experimental initiative called the Recreational Fee Demonstration Program. Under the trial program, the Congress authorized the four federal land management agencies, including the Forest Service, to charge fees to visitors and to retain the revenues for use in addition to other appropriated funds. The Congress originally authorized the program for 3 years and has extended it several times. As Congress considers whether to extend the program or to make it permanent, the Chairman of the Subcommittee on Forests and Forest Health asked GAO to address several questions about the Forest Service's administration of the program: (1) How are spending priorities determined for the revenues generated by the program? (2) How has the agency spent its fee demonstration program revenues? (3) What, if anything, is the agency doing to measure the impact of the recreation fee revenues on reducing the agency's deferred maintenance backlog? (4) How does the agency account for its fee demonstration program revenues?"

A letter report issued by the General Accounting Office with an abstract that begins "Today's workers will rely to a large extent on Social Security, private pensions, and personal wealth for their retirement income. But some analysts question whether these sources will provide sufficient retirement income to maintain workers' standards of living once they leave the labor force. Indeed, the Social Security trust funds are projected to become exhausted in 2042, at which time, unless action is taken, Social Security will not be able to pay scheduled benefits in full. To gain an understanding of what today's workers might expect to receive in terms of retirement income, GAO was asked to examine (1) how the personal wealth of Baby Boom (born between 1946 and 1964) and Generation X (born between 1965 and 1976) workers compare with what current retirees had at similar ages, (2) how workers from the Baby Boom and Generation X compare in terms of the pension and Social Security benefits they can expect to receive, and (3) the likely distribution of pension and Social Security benefits across workers within the Baby Boom and Generation X."

A letter report issued by the General Accounting Office with an abstract that begins "The Workforce Investment Act (WIA) of 1998 required states to streamline employment and training services and established three separate funding streams for serving youth, adults, and dislocated workers, for which about $3.3 billion was appropriated for fiscal year 2003. The formulas for distributing these funds to the states were left largely unchanged from those used to distribute funds under the Job Training Partnership Act of 1982, which served a different set of target populations. In anticipation of the upcoming debates on WIA's reauthorization, Congress asked us to review the formulas in the context of current program goals. Specifically, we assessed the formulas used to distribute funds to the states, identifying any mismatches that might exist between the formulas and WIA's program goals and populations served and identifying where the formulas are most vulnerable to wide fluctuations in funding levels from year to year. To identify issues associated with the current formulas, we: (1) summarized relevant provisions of the WIA statute and compared formula factors with target populations for each program, (2) analyzed the U.S. Department of Labor's formula calculations and states' historical allocations to identify factors …

A letter report issued by the General Accounting Office with an abstract that begins "Given the magnitude of its reported spending on information technology (IT) services--more than $6.2 billion in fiscal year 2001--it is critical that the Department of Defense (DOD) adopt effective practices for acquiring IT services. GAO researched leading commercial practices for the outsourcing of IT services, and, in November 2001, published a framework consisting of seven phases that span the full range of activities that are performed during the outsourcing of those services (this is an acquisition in which a client organization transfers responsibility for performing services to an external provider). GAO was asked to determine (1) the extent to which selected DOD projects for outsourcing IT services use leading commercial practices as specified in GAO's framework and (2) whether DOD is sharing lessons learned from its IT outsourcing projects across the department."

This paper presents a study of non-Darcy fluid flow through porous and fractured rock, which may occur near wells during high-flux injection of waste fluids into underground formations. Both numerical and analytical models are used in this study. General non-Darcy flow is described using the Forchheimer equation, implemented in a three-dimensional, multiphase flow reservoir simulator. The non-Darcy flow through a fractured reservoir is handled using a general dual continuum approach, covering commonly used conceptual models, such as double porosity, dual permeability, explicit fracture, etc. Under single-phase flow conditions, an approximate analytical solution, as an extension of the Warren-Root solution, is discussed. The objectives of this study are (1) to obtain insights into the effect of non-Darcy flow on transient pressure behavior through porous and fractured reservoirs and (2) to provide type curves for well test analyses of non-Darcy flow wells. The type curves generated include various types of drawdown, injection, and buildup tests with non-Darcy flow occurring in porous and fractured reservoirs. In addition, non-Darcy flow into partially penetrating wells is also considered. The transient-pressure type curves for flow in fractured reservoirs are based on the double-porosity model. Type curves provided in this work for non-Darcy flow in porous and …

OAK B204 We have been pursuing a multi-year project, funded by the U.S. Department of Energy, to study neutron scattering interactions in iron. The principal objective of this work is to investigate the well-known deficiency that exists for reactor pressure vessel neutron fluence determinations. Specifically, we are using the spherical-shell transmission method, employing iron shells with different thicknesses, and neutron time-of-flight (TOF) measurements of the scattered neutrons, in an effort to precisely determine specific energy regions over which deficiencies in the non-elastic scattering cross section for neutron scattering in iron appear to exist.

This is the tenth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT41047. The goal of the project is to develop and demonstrate a computational workbench for simulating the performance of Vision 21 Power Plant Systems. Within the last quarter, good progress has been made on all aspects of the project. Calculations for a full Vision 21 plant configuration have been performed for two gasifier types. An improved process model for simulating entrained flow gasifiers has been implemented into the workbench. Model development has focused on: a pre-processor module to compute global gasification parameters from standard fuel properties and intrinsic rate information; a membrane based water gas shift; and reactors to oxidize fuel cell exhaust gas. The data visualization capabilities of the workbench have been extended by implementing the VTK visualization software that supports advanced visualization methods, including inexpensive Virtual Reality techniques. The ease-of-use, functionality and plug-and-play features of the workbench were highlighted through demonstrations of the workbench at a DOE sponsored coal utilization conference. A white paper has been completed that contains recommendations on the use of component architectures, model interface protocols and software frameworks for developing a Vision 21 plant simulator.

A multi-grid part-in-cell algorithm for a shearless slab drift wave model with kinetic electrons is presented. The algorithm, which is based on an exact separation of adiabatic and nonadiabatic electron responses, is used to investigate the presence of strange attractors in drift wave turbulence. Although the simulation model has a large number of degrees of freedom, it is found that the strange attractor is low-dimensional and that it is strongly affected by dissipative (collisional) effects.

Inertia welding is widely used to join cylindrically shaped objects such as disks and shafts in turbine engines, turbochargers, etc. Flash control in many of these applications is not critical because the excess material is on external surfaces and can readily be removed by machining. Internal flash on hollow vessels, however, may be difficult or impossible to remove and may be either controlled by the use of flash traps or the part can be used as welded. Both internal flash and flash traps reduce internal volume and the conditions are not always acceptable. To address this short-coming, several innovative methods have been tested to determine their effect on flash control in inertia welding of hollow vessels. The methods include introduction of high pressure inert gas and incorporation of an expendable mandrel to divert the flash. Both gas and internal mandrels appear promising methods for diverting flash.

Recent modifications to the minimum energy efficiency requirements for residential water heaters have spurred an investigation into the variability in testing high-efficiency electric water heaters. While initial inter-laboratory comparisons showed excellent agreement between test results from different labs, subsequent inter-laboratory comparisons show differences between measured energy factors of up to 0.040. To determine the source of these differences, analyses of various parts of the test procedure are performed. For one case studied, the uncertainty in test results can be as high as +-0.028 if instrument accuracies reach the minimum level allowed in the test procedure. Other areas of the test procedure where variability is introduced are the optional use of pre-draws, the location of the lower tank temperature-measuring device, the use of insulation on tank fittings, and the use of a warm-up period before the simulated-use test commences. The implications of these issues on test results are provided.

Motivation. The power of multi-sequence comparison forbiological discovery is well established and sequence data from a growinglist of organisms is becoming available. Thus, a need exists forcomputational strategies to visually compare multiple aligned sequencesto support conservation analysis across various species. To be efficientthese visualization algorithms require the ability to universally handlea wide range of evolutionary distances while taking into accountphylogeny Results. We have developed Phylo-VISTA, an interactive tool foranalyzing multiple alignments by visualizing the similarity of DNAsequences among multiple species while considering their phylogenicrelationships. Features include a broad spectrum of resolution parametersfor examining the alignment and the ability to easily compare any subtreeof sequences within a complete alignment dataset. Phylo-VISTA uses VISTAconcepts that have been successfully applied previously to a wide rangeof comparative genomics data analysis problems. Availability Phylo-VISTAis an interactive java applet available for downloading athttp://graphics.cs.ucdavis.edu/~;nyshah/Phylo-VISTA. It is also availableon-line at http://www-gsd.lbl.gov/phylovista and is integrated with theglobal alignment program LAGAN athttp://lagan.stanford.edu.Contactphylovista@lbl.gov

A hydrogen safety sensor is presented which provides high sensitivity and fast response time when operated in air. The target application for the sensor is external deployment near systems using or producing high concentrations of hydrogen. The sensor is composed of a catalytically active metal-oxide sensing electrode and a noble metal reference electrode attached to an yttria-stabilized zirconia (YSZ) electrolyte. The sensing approach is based on the difference in oxidation rate of hydrogen on the different electrode materials. Results will be presented for a sensor using a sensing electrode of tin-doped indium oxide (ITO). Response to H{sub 2}, and cross-sensitivity to hydrocarbon and H{sub 2}O are discussed.
