The Spending Pipeline: Stages of Federal Spending (open access)

The Spending Pipeline: Stages of Federal Spending

Federal government spending involves a multi-step process in which budget authority is enacted and obligated, and outlays are generated. Budget authority is enacted in law; it provides federal agencies the legal basis to incur obligations. Obligations, which reflect such activities as employing personnel, entering into contracts, and submitting purchase orders, establish financial liabilities of the federal government. Outlays are payments that liquidate these obligations. This multi-step process can be illustrated as a spending pipeline

Risk assessment of high altitude free flight commercial aircraft operations (open access)

Risk assessment of high altitude free flight commercial aircraft operations

A quantitative model is under development to assess the safety and efficiency of commercial aircraft operations under the Free Flight Program proposed for air traffic control for the US National Airspace System. The major objective of the Free Flight Program is to accommodate the dramatic growth anticipated in air traffic in the US. However, the potential impacts upon aircraft safety from implementing the Program have not been fully explored and evaluated. The model is directed at assessing aircraft operations at high altitude over the continental US airspace since this action is the initial step for Free Flight. Sequential steps with analysis, assessment, evaluation, and iteration will be required to satisfactorily accomplish the complete transition of US commercial aircraft traffic operations.

Role of the NIF in the development of ICF applications (open access)

Role of the NIF in the development of ICF applications

The National Ignition Facility (NIF) is a 1.8 MJ (at 351 nm), 192 beam laser facility being built at the Lawrence Livermore National Laboratory (LLNL) to achieve inertial fusion ignition in the laboratory. The NIF Project is being designed and built by a team from LLNL, Los Alamos National Laboratory, Sandia National Laboratory, and the University of Rochester. When completed in 2003, it will be a multipurpose facility that will be used for many applications in national security, energy, and the basic sciences. In addition to the National Security Mission, these applications include, for example, electric power generation, space propulsion, and study of basic astrophysical phenomena in the laboratory. Such applications receive benefit both through the state- of-the-art technology developments necessary to build NIF and through specific experiments that will be performed on NIF.

Fatigue of LX-14 and LX-19 plastic bonded explosives (open access)

Fatigue of LX-14 and LX-19 plastic bonded explosives

The DOD uses the plastic bonded explosive (PBX) LX-14 in a wide variety of applications including shaped charges and explosively forged projectiles. LX- 19 is a higher energy explosive, which could be easily substituted for LX-14 because it contains the identical Estane 5703p binder and more energetic CL-20 explosive. Delivery systems for large shaped charges, such as TOW-2, include the Apache helicopter. Loads associated with vibrations and expansion from thermal excursions in field operations may, even at low levels over long time periods, cause flaws, already present in the PBX to grow. Flaws near the explosive/liner interface of a shaped charge can reduce performance. Small flaws in explosives are one mechanism (the hot spot mechanism) proposed for initiation and growth to detonation of PBXs like LX-14, PBXN 5, LX-04 and LX-17 among others. Unlike cast-cured explosives and propellants, PBXs cannot usually be compression molded to full density. Generally, the amount of explosive ignited by a shock wave is approximately equal to the original void volume. Whether or not these flaws or cracks grow during field operations to an extent sufficient to adversely affect the shaped charge performance or increase the vulnerability of the PBX is the ultimate question this effort …

Interface control document for tank waste remediation system privatization phase 1 infrastructure support Project W-519

This document describes the functional and physical interfaces between the Tank Waste Remediation System (TWRS) Privatization Phase 1 Infrastructure Project W-519 and the various other projects (i.e., Projects W-314, W-464, W-465, and W-520) supporting Phase 1 that will require the allocation of land in and about the Privatization Phase 1 Site and/or interface with the utilities extended by Project W-519. Project W-519 will identify land use allocations and upgrade/extend several utilities in the 200-East Area into the Privatization Phase 1 Site (formerly the Grout Disposal Compound) in preparation for the Privatization Contractors (PC) to construct treatment facilities. The project will upgrade/extend: Roads, Electrical Power, Raw Water (for process and fire suppression), Potable Water, and Liquid Effluent collection. The replacement of an existing Sanitary Sewage treatment system that may be displaced by Phase 1 site preparation activities may also be included.

Structure of Mesita del Buey at TA-54, Los Alamos National Laboratory, New Mexico (open access)

Structure of Mesita del Buey at TA-54, Los Alamos National Laboratory, New Mexico

The geological structure of Mesita del Buey at Technical Area 54 (TA-54) was examined using precise surveying of the contact between units 1v and 2 of the Tshirege Member of the Bandelier Tuff at 3.5 km along the north wall of Pajarito Canyon and 0.6 km along the north wall of a tributary to Canada del Buey. Estimated structure contours on this contact indicate typical strikes of N40E to N70E along this part of Mesita del Buey, although the apparent strike of the tuff is E-W at the western part of the survey. Typical dips are 1.0{degree} to 2.0{degree} to the east or southeast, with an estimated maximum dip of 3.2{degree} near the west end of Material Disposal Area G. Thirty seven faults with vertical displacements of 5 to 65 cm were observed in outcrop along the Pajarito Canyon traverse, and, due to the incomplete exposure of the unit 1v-unit 2 contact, many more faults of this magnitude undoubtedly exist. The faults have a wide range in strike and have either down-to-the-west and down-to-the-east components of offset, although about 65% of the observed displacement is down-to-the-west or northwest. These faults are not clearly associated with major fault zones, indicated by …

Advanced reservoir characterization in the Antelope Shale to establish the viability of CO{sub 2} enhanced oil recovery in California`s Monterey Formation siliceous shales. Quarterly progress report, January 1--March 31, 1998 (open access)

Advanced reservoir characterization in the Antelope Shale to establish the viability of CO{sub 2} enhanced oil recovery in California`s Monterey Formation siliceous shales. Quarterly progress report, January 1--March 31, 1998

The primary objective of this research is to conduct advanced reservoir characterization and modeling studies in the Antelope Shale reservoir. Characterization studies will be used to determine the technical feasibility of implementing a CO{sub 2} enhanced oil recovery project in the Antelope Shale in Buena Vista Hills Field. The Buena Vista Hills pilot CO{sub 2} project will demonstrate the economic viability and widespread applicability of CO{sub 2} flooding in fractured siliceous shale reservoirs of the San Joaquin Valley. The research consists of four primary work processes: Reservoir Matrix and Fluid Characterization; Fracture Characterization; Reservoir Modeling and Simulation; and CO{sub 2} Pilot Flood and Evaluation. Work done in these areas is subdivided into two phases or budget periods. The first phase of the project focused on the application of a variety of advanced reservoir characterization techniques to determine the production characteristics of the Antelope Shale reservoir. Reservoir models based on the results of the characterization work will be used to evaluate how the reservoir will respond to secondary recovery and EOR processes. The second phase of the project will include the implementation and evaluation of an advanced enhanced oil recovery (EOR) pilot in the United Anticline (West Dome) of the Buena …

Asian Financial Crisis: An Analysis of U.S. Foreign Policy Interests and Options

The principal focus of this report is on the foreign policy ramifications of the Asian financial crisis and U.S. options for addressing them. This report tracks and analyzes the efforts of the most seriously affected Asian countries to deal with their economic and financial problems, and their interaction with the International Monetary Fund (IMF), the United States, and other major sources of financial support and policy advice. It also addresses the implications of the crisis for such U.S. interests as regional stability and the prevention of conflict, trade liberalization, and U.S. regional and global leadership, and discusses the principal factors that could influence the duration and severity of the crisis. A final section considers options for Congress in the context of various criticisms of the IMF’s stabilization programs and the operations of the Fund itself.
