Marketing Strategy Research
This report documents the research that has been undertaken as background for preparation of a marketing campaign for middle and high school students to increase interest in national security careers at the National Nuclear Security Administration. This work is a part of the National Security Preparedness Project (NSPP), being performed under a Department of Energy (DOE)/National Nuclear Security Administration (NNSA) grant. Previous research on the development of a properly trained and skilled national security workforce has identified a lack of interest by k-12 students in the STEM (Science, Technology, Engineering, and Mathematics) fields. Further, participation in these careers by women and minority populations is limited and is not increasing. Added to this are low educational achievement levels in New Mexico, where the marketing campaign will be deployed.

Medicare Recovery Audit Contracting: Weaknesses Remain in Addressing Vulnerabilities to Improper Payments, Although Improvements Made to Contractor Oversight
A letter report issued by the Government Accountability Office with an abstract that begins "The Centers for Medicare & Medicaid Services (CMS) conducted a mandated 3-year project from March 2005 through March 2008 to demonstrate the use of recovery audit contractors (RAC) in identifying Medicare improper payments and recouping overpayments. CMS implemented a mandated national RAC program, which began in March 2009. GAO was asked to examine specific issues that arose during the demonstration project and CMS's efforts to address them in the national RAC program. This report examines the extent to which CMS (1) developed a process and took corrective actions to address vulnerabilities identified by the RACs that led to improper payments, (2) resolved coordination issues between the RACs and the Medicare claims administration contractors, and (3) established methods to oversee RAC claim review accuracy and provider service during the national program. GAO reviewed CMS documents and interviewed officials from CMS and contractors and provider groups affected by the demonstration project."

Photon Science for Renewable Energy
Our current fossil-fuel-based system is causing potentially catastrophic changes to our planet. The quest for renewable, nonpolluting sources of energy requires us to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels. Light-source facilities - the synchrotrons of today and the next-generation light sources of tomorrow - are the scientific tools of choice for exploring the electronic and atomic structure of matter. As such, these photon-science facilities are uniquely positioned to jump-start a global revolution in renewable and carbonneutral energy technologies. In these pages, we outline and illustrate through examples from our nation's light sources possible scientific directions for addressing these profound yet urgent challenges.

Preliminary Evaluation of the Impact of the Section 1603 Treasury Grant Program on Renewable Energy Deployment in 2009
Federal support for renewable energy deployment in the United States has traditionally been delivered primarily through tax benefits, including the production tax credit ('PTC') in Section 45 of the U.S. tax code, investment tax credits ('ITC') in Sections 25D and 48, and accelerated tax depreciation in Section 168. Many renewable power project developers are unable to use the majority of these tax benefits directly or immediately, however, and have therefore often relied on third-party 'tax equity' investors for the necessary investment capital in order to monetize the available tax benefits. As has been well-publicized, most of these tax equity investors were hit hard by the global financial crisis that unfolded in the last months of 2008 and, as a result, most either withdrew from the renewable power market at that time or reduced their available investment capital. This left a significant financing gap beginning in late 2008, and placed at some risk the continued near-term growth of renewable energy supply in the U.S. In recognition of these developments, the U.S. Congress passed two stimulus bills - The Energy Improvement and Extension Act ('the Extension Act') in October 2008 and The American Recovery and Reinvestment Act ('the Recovery Act') in February …

The Prospects of Alternatives to Vapor Compression Technology for Space Cooling and Food Refrigeration Applications
Five alternatives to vapor compression technology were qualitatively evaluated to determine their prospects for being better than vapor compression for space cooling and food refrigeration applications. The results of the assessment are summarized in the report. Overall, thermoacoustic and magnetic technologies were judged to have the best prospects for competing with vapor compression technology, with thermotunneling, thermoelectric, and thermionic technologies trailing behind in that order.

REMOVAL OF CESIUM FROM SAVANNAH RIVER SITE WASTE WITH SPHERICAL RESORCINOL FORMALDEHYDE ION EXCHANGE RESIN EXPERIMENTAL TESTS
A principal goal at the Savannah River Site (SRS) is to safely dispose of the large volume of liquid nuclear waste held in many storage tanks. In-tank ion exchange (IX) columns are being considered for cesium removal. The spherical form of resorcinol formaldehyde ion exchange resin (sRF) is being evaluated for decontamination of dissolved saltcake waste at SRS, which is generally lower in potassium and organic components than Hanford waste. The sRF performance with SRS waste was evaluated in two phases: resin batch contacts and IX column testing with both simulated and actual dissolved salt waste. The tests, equipment, and results are discussed.

Research, Development and Demonstration of Micro-CHP System for Residential Applications
ECR International and its joint venture company, Climate Energy, are at the forefront of the effort to deliver residential-scale combined heat and power (Micro-CHP) products to the USA market. Part of this substantial program is focused on the development of a new class of steam expanders that offers the potential for significantly lower costs for small-scale power generation technology. The heart of this technology is the scroll expander, a machine that has revolutionized the HVAC refrigerant compressor industry in the last 15 years. The liquid injected cogeneration (LIC) technology is at the core of the efforts described in this report, and remains an excellent option for low cost Micro-CHP systems. ECR has demonstrated in several prototype appliances that the concept for LIC can be made into a practical product. The continuing challenge is to identify economical scroll machine designs that will meet the performance and endurance requirements needed for a long life appliance application. This report describes the numerous advances made in this endeavor by ECR International. Several important advances are described in this report. Section 4 describes a marketing and economics study that integrates the technical performance of the LIC system with real-world climatic data and economic analysis to …

ScalaTrace: Tracing, Analysis and Modeling of HPC Codes at Scale
Characterizing the communication behavior of large-scale applications is a difficult and costly task due to code/system complexity and their long execution times. An alternative to running actual codes is to gather their communication traces and then replay them, which facilitates application tuning and future procurements. While past approaches lacked lossless scalable trace collection, we contribute an approach that provides orders of magnitude smaller, if not near constant-size, communication traces regardless of the number of nodes while preserving structural information. We introduce intra- and inter-node compression techniques of MPI events, we develop a scheme to preserve time and causality of communication events, and we present results of our implementation for BlueGene/L. Given this novel capability, we discuss its impact on communication tuning and on trace extrapolation. To the best of our knowledge, such a concise representation of MPI traces in a scalable manner combined with time-preserving deterministic MPI call replay are without any precedence.

Some Considerations Regarding Pulsed Correction of Chromatic Aberrations in Final Focusing Systems
Nearly all designs of accelerators for heavy ion fusion rely on a velocity (energy) ramp to compress the beam longitudinally from its length in the accelerator to the length required at the target. The size of the velocity ramp is constrained by the longitudinal emittance of the beam. For example, if the longitudinal emittance is 0.05 eV {center_dot} s and we wish to produce a pulse having a width of {+-}2.5 ns at the target, we must supply an energy tilt such that the energy spread at the target is at least {+-}0.05 eV {center_dot} s/2.5 ns = {+-}2 x 10{sup 7} eV. The minimal value of energy spread occurs when the beam has propagated to the point where there is no correlation between the time and energy variables of the beam particles. (In the simple approximation where the boundary of the longitudinal phase space containing the particles is an ellipse, the ellipse is erect at this point, i.e., not tilted with respect to the axes.) In any case, the energy spread can affect focusing. If, for example, the beam kinetic energy is of the order of 5 GeV, a tilt of {+-}2 x 10{sup 7} eV corresponds to a …

Stability of modulation transfer function calibration of surface profilometers using binary pseudo-random gratings and arrays with nonideal groove shapes
The major problem of measurement of a power spectral density (PSD) distribution of surface heights with surface profilometers arises due to the unknown Modulation Transfer Function (MTF) of the instruments, which tends to distort the PSD at higher spatial frequencies. The special mathematical properties of binary pseudo-random patterns make them an ideal basis for developing MTF calibration test surfaces. Two-dimensional binary pseudo-random arrays (BPRAs) have been fabricated and used for the MTF calibration of the MicroMap{trademark}-570 interferometric microscope with all available objectives. An investigation into the effects of fabrication imperfections on the quality of the MTF calibration and a procedure for accounting for such imperfections are presented.
