Energy Efficiency and the Rebound Effect: Does Increasing Efficiency Decrease Demand? (open access)

Energy Efficiency and the Rebound Effect: Does Increasing Efficiency Decrease Demand?

Intuitively it seems obvious to most observers that increasing energy efficiency will ultimately reduce demand for an energy resource such as electricity. Paradoxically, economic theory suggests that this decrease in demand and subsequent decrease in cost of using the resource could cause a rebound in demand. A commonly cited example is an increase in the efficiency of home air conditioning which may reduce the resident’s monetary incentive to conserve. The resident may opt to change the thermostat setting to keep the amount he pays constant, but living at a more comfortable temperature. When actually measured this “Rebound Effect” is generally acknowledged to lower predicted reductions in electricity demand by 10%-40% depending on the device that is made more efficient.

Purchase Cards: Control Weaknesses Leave Two Navy Units Vulnerable to Fraud and Abuse

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses internal controls weaknesses that left two Navy units in San Diego, California, vulnerable to purchase card fraud and abuse. GAO found a proliferation of purchase cards at the two units in San Diego--the Space and Naval Warfare Systems Command and the Navy Public Works. In the end, more than 1,700 cardholders essentially had the authority to make their own purchase decisions. A serious breakdown in internal controls over the receipt of government property and the certification of monthly statements, coupled with flawed or nonexistent policies and procedures and the failure of Navy employees to adhere to valid policies and procedures, led to (1) the loss, theft, and misuse of government property; (2) the potential abuse of purchase cards; and (3) payments of potentially fraudulent charges. Five fraud cases have already been identified, and the government remains extremely vulnerable to fraud, waste, and abuse arising from the purchase card program at the two Navy units. This testimony summarized the November report, GAO-02-32."

Army Inventory: Parts Shortages Are Impacting Operations and Maintenance Effectiveness (open access)

Army Inventory: Parts Shortages Are Impacting Operations and Maintenance Effectiveness

A letter report issued by the General Accounting Office with an abstract that begins "The military's ability to carry out its mission depends on its having adequate supplies of spare parts on hand for maintenance and repairs. Shortages are a key indicator that the billions of dollars being spent on these parts are not being used effectively, efficiently, and economically. Despite additional funding from Congress, the Army still has concerns about spare parts shortages. Spare parts shortages for the Apache, Blackhawk, and Chinook helicopters have harmed operations and lowered morale among maintenance personnel. Cannibalization of parts from one aircraft to another is an inefficient practice that results in double work for the maintenance personnel, masks parts shortages, and lowers morale. Parts were unavailable for various reasons, including higher-than-expected demand for parts, delays in obtaining parts from contractors, and problems with overhaul and maintenance. Another factor contributing to the shortage was the Army's inability to obtain parts for these aging aircraft from the original manufacturers, which sometimes had gone out of business. The Army and the Defense Logistics Agency have efforts planned or underway to improve the availability of aviation spare parts. Once these initiatives are further along, GAO will review …

Nuclear Regulation: Progress Made in Emergency Preparedness at Indian Point 2, but Additional Improvements Needed (open access)

Nuclear Regulation: Progress Made in Emergency Preparedness at Indian Point 2, but Additional Improvements Needed

A letter report issued by the General Accounting Office with an abstract that begins "Consolidated Edison Company shut down the Indian Point 2 commercial nuclear power plant in February 2000 because a tube had ruptured in a steam generator, raising the possibility that radioactively contaminated water could leak into the environment. In this case, the total amount of radioactivity released posed no threat because the amount of radioactivity released was about one thousandth of the dose an individual receives from a chest X-ray. However, in the event of a more serious emergency at Indian Point 2, protecting the public from a radioactive release presents more substantial challenges because the plant is located in a heavily populated area. This report reviews issues associated with emergency preparedness protocols associated with the plant. GAO found that a more proactive approach to correct recurring weaknesses could have improved the emergency preparedness plan during the February 2000 emergency. This emergency demonstrated the importance of effective, clear communication networks, both on-site regarding the need to ensure that pagers work well to notify key personnel of an emergency, as well as off-site, regarding communication about the extent and magnitude of the emergency. Exercises, although playing a valuable …

Management Letter: Improvements Needed in IRS' Accounting Procedures and Internal Controls

Correspondence issued by the General Accounting Office with an abstract that begins "In March 2001, GAO issued a report (GAO-01-394) on the results of its audit of the Internal Revenue Service's (IRS) financial statements and on the effectiveness of its internal controls for fiscal year 2000. This report reviews additional matters identified during GAO's fiscal year 2000 audit regarding accounting procedures and internal controls that could be improved. GAO found that IRS had immaterial internal control issues that affected reporting. IRS (1) was unable to determine if its costs for reimbursable activities were accurate and whether it was recouping the costs of the goods or services it provided, (2) lacked procedures to properly record its working capital fund prepaid expenses, (3) accepted information from its contractors for inclusion in its year-end financial reporting without sufficient oversight or review, and (4) did not always follow standard procedures with respect to the transfer of funds between appropriations."

Architecture of a software quench management system (open access)

Architecture of a software quench management system

Testing superconducting accelerator magnets is inherently coupled with the proper handling of quenches; i.e., protecting the magnet and characterizing the quench process. Therefore, software implementations must include elements of both data acquisition and real-time controls. The architecture of the quench management software developed at Fermilab's Magnet Test Facility is described. This system consists of quench detection, quench protection, and quench characterization components that execute concurrently in a distributed system. Collaboration between the elements of quench detection, quench characterization and current control are discussed, together with a schema of distributed saving of various quench-related data. Solutions to synchronization and reliability in such a distributed quench system are also presented.

Reactions Involved in Fingerprint Development Using the Cyanoacrylate - Fuming Method

The Learning Objective is to present the basic chemistry research findings to the forensic community regarding development of latent fingerprints using the cyanoacrylate fuming method. Chemical processes involved in the development of latent fingerprints using the cyanoacrylate fuming method have been studied, and will be presented. Two major types of latent prints have been investigated--clean (eccrine) and oily (sebaceous) prints. Scanning electron microscopy (SEM) was used as a tool for determining the morphology of the polymer developed separately on clean and oily prints after cyanoacrylate fuming. A correlation between the chemical composition of an aged latent fingerprint, prior to development, and the quality of a developed fingerprint was observed in the morphology. The moisture in the print prior to fuming was found to be a critical factor for the development of a useful latent print. In addition, the amount of time required to develop a high quality latent print was found to be minimal. The cyanoacrylate polymerization process is extremely rapid. When heat is used to accelerate the fuming process, typically a period of 2 minutes is required to develop the print. The optimum development time is dependent upon the concentration of cyanoacrylate vapors within the enclosure.

Mechanical, Electrical, and Environmental Evaluation of Nano-Miniature Connectors

Because of their small size (0.025-inch spacing), nano-miniature connectors have been chosen for JTA telemetry applications. At the time they were chosen, extensive testing had not been done to determine the mechanical, electrical, and environmental characteristics of these connectors at the levels required for use by weapon systems. Since nano-miniature connectors use some unique plating and wire crimping processes not used in most design agency connectors, it was decided that these properties should be tested thoroughly. This report describes the results of that testing.

A method for calculating longitudinal phase space distribution when given the time profile of the bunch

We will show in this paper a method for calculating the longitudinal phase space distribution when the time profile of the bunch as measured by a wall current monitor is given. The key to this method is the assumption that the bunch is matched to the bucket. With this assumption, we will show that the method boils down to solving a simple upper triangular matrix equation. We will also illustrate the method with two examples and show the method's shortcomings.

Design and development of Nb{sub 3}Sn single-layer common coil dipole magnet for VLHC (open access)

Design and development of Nb{sub 3}Sn single-layer common coil dipole magnet for VLHC

Common coil dipole magnets based on Nb{sub 3}Sn conductor and the React and Wind technology are a promising option for the next generation of hadron colliders. The react and wind technology has potential cost benefits in terms of cable insulation, structural materials and magnet fabrication. A common coil design allows the use of pre-reacted Nb{sub 3}Sn superconductor with low critical current degradation after bending. Fermilab in collaboration with LBNL is involved in the development of a single-layer common-coil dipole magnet with maximum field of 11 T and 40-50 mm aperture, for a future VLHC. The current magnetic and mechanical designs of the dipole model, magnet parameters along with the status of the program, are reported in this paper.

Analysis of Dyes Extracted from Millimeter-Size Nylon Fibers by Micellar Electrokinetic Chromatography (open access)

Analysis of Dyes Extracted from Millimeter-Size Nylon Fibers by Micellar Electrokinetic Chromatography

The Learning Objective is to present to the forensic community a potential qualitative/quantitative method for trace-fiber color comparisons using micellar electrokinetic chromatography (MEKC). Developing a means of analyzing extracted dye constituents from millimeter-size nylon fiber samples was the objective of this research initiative. Aside from ascertaining fiber type, color evaluation and source comparison of trace-fiber evidence plays a critical role in forensic-fiber examinations. Literally thousands of dyes exist to date, including both natural and synthetic compounds. Typically a three-color-dye combination is employed to affect a given color on fiber material. The result of this practice leads to a significant number of potential dye combinations capable of producing a similar color and shade. Since a typical forensic fiber sample is 2 mm or less in length, an ideal forensic dye analysis would qualitatively and quantitatively identify the extracted dye constituents from a sample size of 1 mm or smaller. The goal of this research was to develop an analytical method for comparing individual dye constituents from trace-fiber evidence with dyes extracted from a suspected source, while preserving as much of the original evidence as possible.

Lower-Temperature Invert Design For Diffusion Barrier

The objective of this analysis is to advance the state of the subsurface facilities design to primarily support the ''Yucca Mountain Science and Engineering Report'' (DOE 2001) and to also support the preparation and revision of System Description Document's Section 2 system descriptions (CRWMS M&O 2001, pp. 9 and 11). The results may also eventually support the License Application (CRWMS M&O 2001, p. 3). The Performance Assessment Department will be the primary user of the information generated and will be used in abstraction modeling for the lower-temperature scenario (CRWMS M&O 200 1, p. 27). This analysis will evaluate the invert relative to the lower- and higher-temperature conditions in accordance with the primary tasks below. Invert design is a major factor in allowing water entering the drift to pass freely and enter the drift floor without surface ponding and in limiting diffusive transport into the host rock. Specific cost effective designs will be conceptualized under the new lower-temperature conditions in this analysis. Interfacing activities and all aspects of Integrated Safety Management and Nuclear Culture principles are included in this work scope by adhering to the respective principles during this design activity and by incorporating safety into the design analysis (CRWMS M&O …

Shoe-String Automation

Faced with a downsizing organization, serious budget reductions and retirement of key metrology personnel, maintaining capabilities to provide necessary services to our customers was becoming increasingly difficult. It appeared that the only solution was to automate some of our more personnel-intensive processes; however, it was crucial that the most personnel-intensive candidate process be automated, at the lowest price possible and with the lowest risk of failure. This discussion relates factors in the selection of the Standard Leak Calibration System for automation, the methods of automation used to provide the lowest-cost solution and the benefits realized as a result of the automation.

Advanced Hydrogen Transport Membranes for Vision 21 Fossil Fuel Plants (open access)

Advanced Hydrogen Transport Membranes for Vision 21 Fossil Fuel Plants

Eltron Research Inc., and team members, are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. This objective is being pursued using dense membranes based in part on Eltron-patented ceramic materials with a demonstrated ability for proton and electron conduction. The technical goals are being addressed by modifying single-phase and composite membrane composition and microstructure to maximize proton and electron conductivity without loss of material stability. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, ceramic, cermet (ceramic/metal), and thin film membranes were prepared, characterized, and evaluated for H{sub 2} transport. For selected ceramic membrane compositions an optimum range for transition metal doping was identified, and it was determined that highest proton conductivity occurred for two-phase ceramic materials. Furthermore, a relationship between transition metal dopant atomic number and conductivity was observed. Ambipolar conductivities of {approx}6 …
