A survey on wind power ramp forecasting. (open access)

A survey on wind power ramp forecasting.

The increasing use of wind power as a source of electricity poses new challenges with regard to both power production and load balance in the electricity grid. This new source of energy is volatile and highly variable. The only way to integrate such power into the grid is to develop reliable and accurate wind power forecasting systems. Electricity generated from wind power can be highly variable at several different timescales: sub-hourly, hourly, daily, and seasonally. Wind energy, like other electricity sources, must be scheduled. Although wind power forecasting methods are used, the ability to predict wind plant output remains relatively low for short-term operation. Because instantaneous electrical generation and consumption must remain in balance to maintain grid stability, wind power's variability can present substantial challenges when large amounts of wind power are incorporated into a grid system. A critical issue is ramp events, which are sudden and large changes (increases or decreases) in wind power. This report presents an overview of current ramp definitions and state-of-the-art approaches in ramp event forecasting.

War Powers Resolution: Presidential Compliance (open access)

War Powers Resolution: Presidential Compliance

Two separate but closely related issues confront Congress each time the President introduces armed forces into a situation abroad that conceivably could lead to their involvement in hostilities. One issue concerns the division of war powers between the President and Congress, whether the use of armed forces falls within the purview of the congressional power to declare war and the War Powers Resolution. The other issue is whether or not Congress concurs in the wisdom of the action. A longer-term issue is whether the War Powers Resolution is an appropriate and effective means of assuring congressional participation in actions that might get the United States involved in war.

Accurate Alignment of Plasma Channels Based on Laser Centroid Oscillations (open access)

Accurate Alignment of Plasma Channels Based on Laser Centroid Oscillations

A technique has been developed to accurately align a laser beam through a plasma channel by minimizing the shift in laser centroid and angle at the channel outptut. If only the shift in centroid or angle is measured, then accurate alignment is provided by minimizing laser centroid motion at the channel exit as the channel properties are scanned. The improvement in alignment accuracy provided by this technique is important for minimizing electron beam pointing errors in laser plasma accelerators.

DOD and VA Health Care: Federal Recovery Coordination Program Continues to Expand but Faces Significant Challenges (open access)

DOD and VA Health Care: Federal Recovery Coordination Program Continues to Expand but Faces Significant Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "In 2007, following reports of poor case management for outpatients at Walter Reed Army Medical Center, the Departments of Defense (DOD) and Veterans Affairs (VA) jointly developed the Federal Recovery Coordination Program (FRCP) to coordinate the clinical and nonclinical services needed by severely wounded, ill, and injured servicemembers and veterans. The FRCP, which continues to expand, is administered by VA, and the care coordinators, called Federal Recovery Coordinators (FRC), are VA employees. This report examines (1) whether servicemembers and veterans who need FRCP services are being identified and enrolled in the program, (2) staffing challenges confronting the FRCP, and (3) challenges facing the FRCP in its efforts to coordinate care for enrollees. GAO reviewed FRCP policies and procedures and conducted over 170 interviews of FRCP officials, FRCs, headquarters officials and staff of DOD and VA case management programs, and staff at medical facilities where FRCs are located."

DOE Nuclear Waste: Better Information Needed on Waste Storage at DOE Sites as a Result of Yucca Mountain Shutdown (open access)

DOE Nuclear Waste: Better Information Needed on Waste Storage at DOE Sites as a Result of Yucca Mountain Shutdown

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy's (DOE) Office of Environmental Management (EM) is responsible for storing and managing a total of about 13,000 metric tons of nuclear waste--spent nuclear fuel and high-level waste--at five DOE sites in Colorado, Idaho, New York, South Carolina, and Washington. Also, a joint DOE-Navy program stores spent nuclear fuel from warships at DOE's Idaho site. DOE and the Navy intended to permanently dispose of this nuclear waste at a repository planned for Yucca Mountain in Nevada. However, that plan is now in question because of actions taken to terminate the site. This report assesses (1) agreements DOE and the Navy have with states at the five sites and the effects a termination of the Yucca Mountain repository would have on their ability to fulfill these agreements; (2) the effects a termination would have on DOE's and the Navy's operations and costs for storing the waste; and (3) DOE's and the Navy's plans to mitigate these potential effects. GAO reviewed state agreements and DOE plans, visited waste facilities, and interviewed federal and state officials."

Electromagnetic Transport From Microtearing Mode Turbulence (open access)

Electromagnetic Transport From Microtearing Mode Turbulence

This Letter presents non-linear gyrokinetic simulations of microtearing mode turbulence. The simulations include collisional and electromagnetic effects and use experimental parameters from a high beta discharge in the National Spherical Torus Experiment (NSTX). The predicted electron thermal transport is comparable to that given by experimental analysis, and it is dominated by the electromagnetic contribution of electrons free streaming along the resulting stochastic magnetic field line trajectories. Experimental values of flow shear can significantly reduce the predicted transport.

End-Stage Renal Disease: CMS Should Assess Adequacy of Payment When Certain Oral Drugs Are Included and Ensure Availability of Quality Monitoring Data (open access)

End-Stage Renal Disease: CMS Should Assess Adequacy of Payment When Certain Oral Drugs Are Included and Ensure Availability of Quality Monitoring Data

A letter report issued by the Government Accountability Office with an abstract that begins "For most individuals with end-stage renal disease (ESRD), Medicare purchases a bundle of dialysis-related services using a single payment. In 2014, the Centers for Medicare & Medicaid Services (CMS) plans to include in this bundled payment "oral-only" ESRD drugs used to treat mineral and bone disorder. Currently, Medicare generally pays for these drugs only if the beneficiary has Part D prescription drug coverage. This report (1) describes the rationales for including oral-only ESRD drugs in the bundled payment, (2) examines dialysis organizations' recent experience providing oral-only ESRD drugs and their future ability to provide these drugs, (3) examines the data sources that CMS could use to account for oral-only ESRD drugs in the bundled payment, and (4) examines CMS's ability to monitor treatment of mineral and bone disorder. GAO interviewed CMS officials, experts in mineral and bone disorder, and representatives of 4 large and 16 small dialysis organizations. GAO also reviewed ESRD payment regulations, related reports, clinical guidelines, and state pharmacy licensure requirements in 10 selected states."
