Highway Safety: Foresight Issues Challenge DOT's Efforts to Assess and Respond to New Technology-Based Trends

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Fatalities on U.S. roads now total over 40,000 each year. Future reductions may require the Department of Transportation (DOT) to address new trends such as evolving crash-avoidance technologies and rapidly changing electronic devices that may distract drivers who use them on the road. (See figure.) GAO was asked to examine how DOT is addressing fast-moving trends such as these. This report examines how… more

A History of Federal Estate, Gift, and Generation-Skipping Taxes

Description: Three primary categories of legislation pertaining to transfer taxes have been introduced in the 110th Congress. As noted above, the repeal of the estate and generation-skipping taxes is not permanent. One category would make the repeal permanent. (See, H.R. 411 and H.R. 2380). Another category would accelerate the repeal of these transfer taxes. (See, H.R. 25, H.R. 1040, H.R. 1586, H.R. 4042, S. 1025, S. 1040, and S. 1081). The third would reinstate these taxes at lower rates and/or in a manne… more

Development and Testing of a Life Cycle Model and a Parameterization of Thin Mid-level Stratiform Clouds

Description: We used a cloud-resolving model (a detailed computer model of cloud systems) to evaluate and improve the representation of clouds in global atmospheric models used for numerical weather prediction and climate modeling. We also used observations of the atmospheric state, including clouds, made at DOE's Atmospheric Radiation Measurement (ARM) Program's Climate Research Facility located in the Southern Great Plains (Kansas and Oklahoma) during Intensive Observation Periods to evaluate our detailed… more

Tracking Multiple Topics for Finding Interesting Articles

Description: We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address ch… more

Grand Research Questions in the Solid-Earth Sciences Final Scientific/Technical Report

Description: Over the past three decades, Earth scientists have made great strides in understanding our planet’s workings and history. Yet this progress has served principally to lay bare more fundamental questions about the Earth. Expanding knowledge is generating new questions, while innovative technologies and new partnerships with other sciences provide new paths toward answers. A National Academies committee was established to frame some of the great intellectual challenges inherent in the study of the… more

Remaining Sites Verification Package for the 100-F-26:13, 108-F Drain Pipelines, Waste Site Reclassification Form 2005-011

Description: The 100-F-26:13 waste site is the network of process sewer pipelines that received effluent from the 108-F Biological Laboratory and discharged it to the 188-F Ash Disposal Area (126-F-1 waste site). The pipelines included one 0.15-m (6-in.)-, two 0.2-m (8-in.)-, and one 0.31-m (12-in.)-diameter vitrified clay pipe segments encased in concrete. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of veri… more

A Unified Monte Carlo Approach to Fast Neutron Cross Section Data Evaluation.

Description: A unified Monte Carlo (UMC) approach to fast neutron cross section data evaluation that incorporates both model-calculated and experimental information is described. The method is based on applications of Bayes Theorem and the Principle of Maximum Entropy as well as on fundamental definitions from probability theory. This report describes the formalism, discusses various practical considerations, and examines a few numerical examples in some detail.

International Linear Collider Accelerator Physics R&D

Description: ILC work at Illinois has concentrated primarily on technical issues relating to the design of the accelerator. Because many of the problems to be resolved require a working knowledge of classical mechanics and electrodynamics, most of our research projects lend themselves well to the participation of undergraduate research assistants. The undergraduates in the group are scientists, not technicians, and find solutions to problems that, for example, have stumped PhD-level staff elsewhere. The ILC… more

Surface Modification of Fuel Cladding Materials with Integral Fuel BUrnable Absorber Boron

Description: Integral fuel burnable absorgers (IFBA) are added to some rods in the fuel assembly to counteract excessive reactivity. These IFBA elements (usually boron or gadolinium) are presently incorporated in the U)2 pellets either by mixing in the pellets or as coatings on the pellet surface. In either case, the incorporation of ifba into the fuel has to be performed in a nuclear-regulated facility that is physically separated from the main plant. These operations tend to be costly and can add from 20 … more

Quantum Phase Transitions and New Scales in QCD-Like Theories

Description: It is commonly believed that in confining vector-like gauge theories the center and chiral symmetry realizations are parametrically entangled, and if phase transitions occur, they must take place around the strong scale {Lambda}{sup -1} of the gauge theory. We demonstrate that (non-thermal) vector-like theories formulated on R{sup 3} x S{sup 1} where S{sup 1} is a spatial circle exhibit new dynamical scales and new phenomena. There are chiral phase transitions taking place at {Lambda}{sup -1}/N… more

The Design, Construction, and Operation of Long-Distance High-Voltage Electricity Transmission Technologies.

Description: This report focuses on transmission lines, which operate at voltages of 115 kV and higher. Currently, the highest voltage lines comprising the North American power grid are at 765 kV. The grid is the network of transmission lines that interconnect most large power plants on the North American continent. One transmission line at this high voltage was built near Chicago as part of the interconnection for three large nuclear power plants southwest of the city. Lines at this voltage also serve mark… more
