Reservoir characterization and performance predictions for the E.N. Woods lease
The task of this work was to evaluate the past performance of the E.N. WOODS Unit and to forecast its future economic performance by taking into consideration the geology, petrophysics and production history of the reservoir. The Decline Curve Analysis feature of the Appraisal of Petroleum Properties including Taxation Systems (EDAPT) software along with the Production Management Systems (PMS) software were used to evaluate the original volume of hydrocarbon in place and estimate the reserve. The Black Oil Simulator (BOAST II) was then used to model the waterflooding operation and estimate the incremental oil production attributable to the water injection. BOAST II was also used to predict future performance of the reservoir.

Sunfall: a collaborative visual analytics system for astrophysics
Computational and experimental sciences produce and collect ever-larger and complex datasets, often in large-scale, multi-institution projects. The inability to gain insight into complex scientific phenomena using current software tools is a bottleneck facing virtually all endeavors of science. In this paper, we introduce Sunfall, a collaborative visual analytics system developed for the Nearby Supernova Factory, an international astrophysics experiment and the largest data volume supernova search currently in operation. Sunfall utilizes novel interactive visualization and analysis techniques to facilitate deeper scientific insight into complex, noisy, high-dimensional, high-volume, time-critical data. The system combines novel image processing algorithms, statistical analysis, and machine learning with highly interactive visual interfaces to enable collaborative, user-driven scientific exploration of supernova image and spectral data. Sunfall is currently in operation at the Nearby Supernova Factory; it is the first visual analytics system in production use at a major astrophysics project.

Wakefield and RF Kicks Due to Coupler Asymmetry in TESLA-Type Accelerating Cavities
In a future linear collider, such as the International Linear Collider (ILC), trains of high current, low emittance bunches will be accelerated in a linac before colliding at the interaction point. Asymmetries in the accelerating cavities of the linac will generate fields that will kick the beam transversely and degrade the beam emittance and thus the collider performance. In the main linac of the ILC, which is filled with TESLA-type superconducting cavities, it is the fundamental (FM) and higher mode (HM) couplers that are asymmetric and thus the source of such kicks. The kicks are of two types: one, due to (the asymmetry in) the fundamental RF fields and the other, due to transverse wakefields that are generated by the beam even when it is on axis. In this report we calculate the strength of these kicks and estimate their effect on the ILC beam. The TESLA cavity comprises nine cells, one HM coupler in the upstream end, and one (identical, though rotated) HM coupler and one FM coupler in the downstream end (for their shapes and location see Figs. 1, 2) [1]. The cavity is 1.1 m long, the iris radius 35 mm, and the coupler beam pipe radius …

Binary pseudo-random gratings and arrays for calibration of the modulation transfer function of surface profilometers: recent developments
The major problem of measurement of a power spectral density (PSD) distribution of the surface heights with surface profilometers arises due to the unknown Modulation Transfer Function (MTF) of the instruments. The MTF tends to distort the PSD at higher spatial frequencies. It has been suggested [Proc. SPIE 7077-7, (2007), Opt. Eng. 47 (7), 073602-1-5 (2008)] that the instrumental MTF of a surface profiler can be precisely measured using standard test surfaces based on binary pseudo-random (BPR) patterns. In the cited work, a one dimensional (1D) realization of the suggested method based on use of BPR gratings has been demonstrated. Here, we present recent achievements made in fabricating and using two-dimensional (2D) BPR arrays that allow for a direct 2D calibration of the instrumental MTF. The 2D BPRAs were used as standard test surfaces for 2D MTF calibration of the MicromapTM-570 interferometric microscope with all available objectives. The effects of fabrication imperfections on the efficiency of calibration are also discussed.

High pressure phase transformation in iron under fast compression
We present experimental results on the solid-solid, {alpha} to {epsilon} phase transformation kinetics of iron under high pressure dynamic compression. We observe kinetic features - velocity loops - similar with the ones recently reported to occur when water is frozen into its ice VII phase under comparable experimental conditions. We analyze this behavior in terms of general ideas coupling the steady sample compression with phase nucleation and growth with a pressure dependent phase interface velocity. The model is used to predict the response of iron when steadily driven across the {alpha} - {epsilon} phase boundary on very short time scales, including those envisioned to be achieved in ultra-fast laser experiments.

The Foreign Intelligence Surveillance Act: A Sketch of Selected Issues
This report briefly outlines three issues relating to electronic surveillance under the Foreign Intelligence Surveillance Act (FISA) and touches upon some of the perspectives reflected in the ongoing debate. These issues include the inherent and often dynamic tension between national security and civil liberties, particularly rights of privacy and free speech; the need for the intelligence community to be able to efficiently and effectively collect foreign intelligence information from the communications of foreign persons located outside the United States in a changing, fast-paced, and technologically sophisticated international environment or from United States persons abroad, and the differing approaches suggested to meet this need; and limitations of liability for those electronic communication service providers who furnish aid to the federal government in its foreign intelligence collection. Two constitutional provisions, in particular, are implicated in this debate — the Fourth and First Amendments. This report briefly examines these issues and sets them in context.

Why Pi And Mrad
Today it is generally accepted in the ion source and accelerator communities to communicate emittance data with units of {pi} mm mrad or {pi} cm mrad. The emittance of a beam with 2 cm diameter or width and an opening angle of 200 mrad then is written as E=100 {pi} cm mrad. This example shows that {pi} has not been involved when calculating the half-axis product which is the numerical definition for the emittance. Why should we add {pi} to the dimensions? We will explain that this convention is not at all a logical one and is confusing to all those who are entering the field as freshmen or just do not want to become experts by adjusting to strange rules. We therefore propose to skip the ''{pi}'' in the dimension and to add characters as sub- or superscripts to the variable E, which describe the specific kind of emittance formulation used, e.g., E{sub r,r'}, E{sub x,x'}, E{sub rms}, E{sub 4*rms}, E{sub norm}, E{sub area}, and E{sub ellipse}. In a real case, such an emittance naming could appear as E{sub x,x',4rms}{sup norm}. Additionally--to be consistent with cleaning up--the dimension of emittances should be given in centimeters or meters, because rad …

Gasoline Prices: New Legislation and Proposals
The high price of gasoline was an important consideration during the debate on the Energy Policy Act of 2005, H.R. 6. As prices continued to surge, the continuing crisis renewed attention on some issues that were dropped or compromised in the debate over P.L. 109-58, as well as to a number of initiatives to reduce the impact of high prices on consumers. A large number of factors have combined to put pressure on gasoline prices, including increased world demand for crude oil and limited U.S. refinery capacity to supply gasoline to a growing national economy. Among the issues receiving new attention were vehicle fuel economy standards, leasing on the Outer Continental Shelf, and refinery "revitalization" provisions.

Gasoline Prices: New Legislation and Proposals
The continuing crisis of high gasoline prices has led to a broad spectrum of proposed new legislation. Despite passage of the major Energy Policy Act of 2005 (P.L. 109-58) in 2005, many Members are exploring a variety of measures to increase supply and reduce demand in the short term, and to reduce the impact of high prices on consumers. Some are also proposing to revisit longer term policies, some of which were passed up in the process of reaching agreement on P.L. 109-58. This report reviews the major legislative initiatives to deal with the gasoline price issue. To put these proposals in perspective, it first describes some of the factors that have led to the high prices of both crude oil and gasoline.

Numerical Study of Instabilities Driven by Energetic Neutral Beam Ions in NSTX
Recent experimental observations from NSTX [National Spherical Torus Experiment] suggest that many modes in a subcyclotron frequency range are excited during neutral-beam injection (NBI). These modes have been identified as Compressional Alfven Eigenmodes (CAEs) and Global Alfven Eigenmodes (GAEs), which are driven unstable through the Doppler-shifted cyclotron resonance with the beam ions. The injection velocities of the NBI ions in NSTX are large compared to Alfven velocity, V(sub)0 > 3V(sub)A, and a strong anisotropy in the fast-ion pitch-angle distribution provides the energy source for the instabilities. Recent interest in the excitation of Alfven Eigenmodes in the frequency range omega less than or approximately equal to omega(sub)ci, where omega(sub)ci is the ion cyclotron frequency, is related to the possibility that these modes can provide a mechanism for direct energy transfer from super-Alfvenic beam ions to thermal ions. Numerical simulations are required in order to find a self-consistent mode structure, and to include the effects of finite-Larmor radius (FLR), the nonlinear effects, and the thermal plasma kinetic effects.

Prediction of water seepage into a geologic repository for high-level radioactive waste
Predicting the amount of water that may seep into waste emplacement drifts is important for assessing the performance of the proposed geologic repository for high-level radioactive waste at Yucca Mountain, Nevada. The repository would be located in thick, partially saturated fractured tuff that will be heated to above-boiling temperatures as a result of heat generation from the decay of nuclear waste. Since infiltrating water will be subject to vigorous boiling for a significant time period, the superheated rock zone (i.e., rock temperature above the boiling point of water) can form an effective vaporization barrier that reduces the possibility of water arrival at emplacement drifts. In this paper, we analyze the behavior of episodic preferential flow events that penetrate the hot fractured rock, evaluate the impact of such flow behavior on the effectiveness of the vaporization barrier, and discuss the implications for the performance assessment of the repository. A semi-analytical solution is utilized to determine the complex flow processes in the hot rock environment. The solution is applied at several discrete times after emplacement, covering the time period of strongly elevated temperatures at Yucca Mountain.
