Audit Guide: Auditing and Investigating the Internal Control of Government Purchase Card Programs (Supersedes GAO-03-678G) (open access)

Audit Guide: Auditing and Investigating the Internal Control of Government Purchase Card Programs (Supersedes GAO-03-678G)

Guidance issued by the General Accounting Office with an abstract that begins "This publication supersedes GAO-03-678G, Audit Guide: Auditing and Investigating the Internal Control of Government Purchase Card Programs, May 2003. The federal government of the United States--the largest and most complex organization in the world--expended approximately $15 billion through federal organizations' purchase card programs in fiscal year 2002. As the steward of taxpayer dollars, federal agencies are accountable for how purchase cards are used and how the funds are spent. To that end, federal agencies are responsible for establishing and maintaining internal control to provide reasonable assurance that (1) the goals and objectives of the purchase card program are met and (2) safeguards against fraudulent, improper, and abusive purchases are adequate. Recent congressional testimony and inspector general and GAO reports show that some federal agencies do not have adequate internal control over their purchase card programs. Without effective internal control, management has little assurance that fraudulent, improper, and abusive purchases are being prevented or, if occurring, are being promptly detected with appropriate corrective actions taken. A key element of internal control is monitoring that assesses the quality of performance over time and ensures that the findings of audits and …

Advanced Interactive Facades - Critical Elements for Future GreenBuildings? (open access)

Advanced Interactive Facades - Critical Elements for Future GreenBuildings?

Building designers and owners have always been fascinated with the extensive use of glass in building envelopes. Today the highly glazed facade has almost become an iconic element for a 'green building' that provides daylighting and a visual connection with the natural environment. Even before the current interest in green buildings there was no shortage of highly glazed building designs. But many of these buildings either rejected sunlight, and some associated daylight and view with highly reflective glazings or used highly transmissive glass and encountered serious internal comfort problems that could only be overcome with large HVAC systems, resulting in significant energy, cost and environmental penalties. From the 1960's to the 1990's innovation in glazing made heat absorbing glass, reflective glass and double glazing commonplace, with an associated set of aesthetic features. In the last decade there has been a subtle shift from trying to optimize an ideal, static design solution using these glazings to making the facade responsive, interactive and even intelligent. More sophisticated design approaches and technologies have emerged using new high-performance glazing, improved shading and solar control systems, greater use of automated controls, and integration with other building systems. One relatively new architectural development is the double …

Progress Report for the Advanced Large-Area Plastic Scintillator (ALPS) Project: FY 2003 Final (open access)

Progress Report for the Advanced Large-Area Plastic Scintillator (ALPS) Project: FY 2003 Final

The DOE tasked PNNL to investigate possible technological avenues for substantially advancing the state-of-the-art in gamma detection via large-area plastic scintillators. This report describes progress on this project as of the conclusion of FY 2003. The primary focus of the report is on experimental tests conducted with a single large-area plastic scintillator outfitted with a variety of photomultiplier tube configurations. Measurements performed to date incude scintillator response under broad-area exposure to various point-like gamma sources, and light-output uniformity mappings obtained by varying the position of a collimated beta-source over the surface of the scintillator. Development of a Monte Carlo program for modeling the response of a large-area scintillator sensor to ionizing radiation, explicitly including resolution-broadening effects of scintillation light generation, propagation, and collection is also described.

Hybrid Power System with a Controlled Energy Storage: Preprint (open access)

Hybrid Power System with a Controlled Energy Storage: Preprint

We investigated a small isolated hybrid power system that used two types of power generation; wind turbine and diesel generation. The interaction of diesel generation, the wind turbine, and the local load is complicated because both the load and the wind turbine fluctuate during the day. These fluctuations create imbalances in power distribution (energy sources are not equal to energy sinks) that can affect the frequency and the voltage in the power system. The addition of energy storage will help balance the distribution of power in the power network. For this paper, we studied the interaction among hybrid power system components and the relative size of the components. We also show how the contribution of wind energy affects the entire power system and distribution and the role of energy storage under the transient conditions caused by load changes and wind turbine start ups.

Wind Turbine Response to Analytic Inflow Vortex Parameters Variation: Preprint (open access)

Wind Turbine Response to Analytic Inflow Vortex Parameters Variation: Preprint

As larger wind turbines are placed on taller towers, rotors frequently operate in atmospheric conditions that support organized, coherent turbulent structures. It is hypothesized that these structures have a detrimental impact on the blade fatigue life experienced by the wind turbine. These structures are extremely difficult to identify with sophisticated anemometry such as ultra-sonic anemometers. In order to ascertain the idealized worst-case scenario for vortical inflow structures impinging on a wind turbine rotor, we created a simple, analytic vortex model. The Rankine vortex model assumes the vortex core undergoes solid body rotation to avoid a singularity at the vortex center and is surrounded by a 2-dimensional potential flow field. Using the wind turbine as a sensor and the FAST wind turbine dynamics code with limited degrees of freedom, we determined the aerodynamic loads imparted to the wind turbine by the vortex structure. The size, strength, rotational direction, plan e of rotation, and location of the vortex were varied over a wide range of operating parameters. We identified the vortex conformation with the most significant effect on blade root bending moment cycle amplitude. Vortices with radii on the scale of the rotor diameter or smaller caused blade root bending moment cyclic …

Productivity Enhancement for Manufacturing of Amorphous Silicon PV Modules: Final Technical Report, 1 July 2002--30 June 2003 (open access)

Productivity Enhancement for Manufacturing of Amorphous Silicon PV Modules: Final Technical Report, 1 July 2002--30 June 2003

During Phase I, EPV conducted parallel research efforts for achieving higher stabilized module power output through improvements in several manufacturing processing steps, with particular emphasis on the thin-film deposition process. The dual goals of achieving a 10% gain in stabilized output and a 20% reduction in direct costs were accomplished. Early in Phase I, a thorough evaluation of single-junction and tandem amorphous silicon (a-Si) modules was carried out with the goal of determining the best option to use (as a function of application) based on EPV's proprietary batch deposition process. The analysis considered total energy delivery over realistic conditions and the impact on equipment needs and production costs. EPV has concluded that the tandem process is more appropriate for its needs at this time. The overall objective of this subcontract over its two-year duration is to continue the advancement of EPV's a-Si production manufacturing technology and improve the product ion equipment used in manufacturing. This will allow EPV to reduce module costs by increasing module output, throughput, and yield.

Final Phase II report : QuickSite(R) investigation, Everest, Kansas. (open access)

Final Phase II report : QuickSite(R) investigation, Everest, Kansas.

The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated grain storage facilities at two different locations at Everest, Kansas (Figure 1.1). One facility (referred to in this report as the Everest facility) was at the western edge of the city of Everest. The CCC/USDA operated this facility from 1950 until the early 1970s. The second facility (referred to in this report as Everest East) was about 0.5 mi northeast of the town. The CCC/USDA operated this facility from 1954 until the early 1970s. While these two former CCC/USDA grain storage facilities were in operation, commercial grain fumigants containing carbon tetrachloride were in common use by the CCC/USDA and the private grain storage industry to preserve grain. In 1997, the Kansas Department of Health and Environment (KDHE) sampled several domestic drinking water and nondrinking water wells in the Everest area. The KDHE sampling was part of the CCC/USDA Private Well Sampling Program, which was initiated to determine whether carbon tetrachloride was present in domestic wells near former CCC/USDA grain storage facilities in Kansas. All of the sampled domestic drinking water wells were located outside the Everest city boundaries. As a result of this sampling, carbon …

Roadmap for Agriculture Biomass Feedstock Supply in the United States (open access)

Roadmap for Agriculture Biomass Feedstock Supply in the United States

The Biomass Research and Development Technical Advisory Committee established a goal that biomass will supply 5% of the nation’s power, 20% of its transportation fuels, and 25% of its chemicals by 2030. These combined goals are approximately equivalent to 30% of the country’s current petroleum consumption. The benefits of a robust biorefinery industry supplying this amount of domestically produced power, fuels, and products are considerable, including decreased demand for imported oil, revenue to the depressed agricultural industry, and revitalized rural economies. A consistent supply of highquality, low-cost feedstock is vital to achieving this goal. This biomass roadmap defines the research and development (R&D) path to supplying the feedstock needs of the biorefinery and to achieving the important national goals set for biomass. To meet these goals, the biorefinery industry must be more sustainable than the systems it will replace. Sustainability hinges on the economic profitability of all participants, on environmental impact of every step in the process, and on social impact of the product and its production. In early 2003, a series of colloquies were held to define and prioritize the R&D needs for supplying feedstock to the biorefinery in a sustainable manner. These colloquies involved participants and stakeholders in …

Captive Rearing Program for Salmon River Chinook Salmon, 2002 Annual Report.

During 2002, the Idaho Department of Fish and Game continued to develop techniques to rear Chinook salmon Oncorhynchus tshawytscha to sexual maturity in captivity and to monitor their reproductive performance under natural conditions. Eyed-eggs were hydraulically collected from redds in the East Fork Salmon River (EFSR; N = 328) and the West Fork Yankee Fork Salmon River (WFYF; N = 308) to establish brood year 2002 culture cohorts. The eyed-eggs were incubated and reared at the Eagle Fish Hatchery, Eagle, Idaho (Eagle). Juveniles collected in 2000 were PIT and elastomer tagged and vaccinated against vibrio Vibrio spp. and bacterial kidney disease prior to being transferred to the NOAA Fisheries, Manchester Marine Experimental Station, Manchester, Washington (Manchester) for saltwater rearing through maturity. Smolt transfers included 203 individuals from the WFYF and 379 from the EFSR. Maturing fish transfers from Manchester to Eagle included 107 individuals from the LEM, 167 from the WFYF, and 82 from the EFSR. This was the second year maturing adults were held on chilled water at Eagle to test if water temperature manipulations could advance spawn timing. Adults from the LEM and WFYF were divided into chilled ({approx} 9 C) and ambient ({approx} 13.5 C) temperature groups …

Walla Walla River Basin Fish Screen Evaluations; Nursery Bridge Fishway and Garden City/Lowden II Sites, 2003 Technical Report.

Pacific Northwest National Laboratory evaluated the fish screens at the Nursery Bridge Fishway and the newly constructed Garden City/Lowden II site west of Walla Walla, Washington, in the Walla Walla River Basin during spring and summer 2003. Both fish screen facilities were examined to determine if they were being effectively operated and maintained to provide for safe fish passage. At the Nursery Bridge Fishway, the screens were evaluated specifically to determine whether the louvers that aid in controlling water flow from behind the screens could be adjusted so that the screens would meet fish protection criteria. Data were collected to determine whether velocities in front of the screens and in the bypasses met current National Oceanic and Atmospheric Administration Fisheries (NOAA Fisheries) (formerly National Marine Fisheries Service (NMFS)) criteria to promote safe and timely fish passage before and after changing the louver settings. Rock weirs downstream of the dam were also evaluated to determine whether they might impede upstream migration of juvenile salmonids during low flow conditions. At the Garden City/Lowden II site, data were collected to establish a baseline for operating conditions and to determine whether any changes in the baffle settings were needed.

Monitoring and Evaluation: Statistical Support for Life-cycle Studies, Annual Report 2003.

The ongoing mission of this project is the development of statistical tools for analyzing fisheries tagging data in the most precise and appropriate manner possible. This mission also includes providing statistical guidance on the best ways to design large-scale tagging studies. This mission continues because the technologies for conducting fish tagging studies continuously evolve. In just the last decade, fisheries biologists have seen the evolution from freeze-brands and coded wire tags (CWT) to passive integrated transponder (PIT) tags, balloon-tags, radiotelemetry, and now, acoustic-tags. With each advance, the technology holds the promise of more detailed and precise information. However, the technology for analyzing and interpreting the data also becomes more complex as the tagging techniques become more sophisticated. The goal of the project is to develop the analytical tools in parallel with the technical advances in tagging studies, so that maximum information can be extracted on a timely basis. Associated with this mission is the transfer of these analytical capabilities to the field investigators to assure consistency and the highest levels of design and analysis throughout the fisheries community. Consequently, this project provides detailed technical assistance on the design and analysis of tagging studies to groups requesting assistance throughout the fisheries …

Chinook Salmon Adult Abundance Monitoring in Lake Creek, Idaho, 2002 Annual Report. (open access)

Chinook Salmon Adult Abundance Monitoring in Lake Creek, Idaho, 2002 Annual Report.

Underwater time- lapse video technology has been used to monitor adult spring and summer chinook salmon (Oncorhynchus tshawytscha) escapement into the Secesh River and Lake Creek, Idaho, since 1998. Underwater time-lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species. Secesh River chinook salmon represent a wild spawning aggregate that has not been directly supplemented with hatchery fish. The Secesh River is also a control stream under the Idaho Salmon Supplementation study. This project has successfully demonstrated the application of underwater video monitoring to accurately quantify chinook salmon abundance in Lake Creek in 1998, 1999, 2001 and 2002. The adult salmon spawner escapement into Lake Creek in 2002 was 410 fish. Jack salmon comprised 7.1 percent of the run. Estimated hatchery composition was 6.1 percent of the spawning run. The first fish passage on Lake Creek was recorded on June 26, 15 days after installation of the fish counting station. Peak net upstream movement of 41 adults occurred on July 8. Peak of total movement activity was August 18. The last fish passed through the Lake Creek fish counting station on September 2. Snow pack in the drainage was 91% of the …
