A letter report issued by the Government Accountability Office with an abstract that begins "Between fiscal years 2010 and 2012, the Department of Homeland Security's (DHS) border and maritime research and development (R&D) components reported producing 97 R&D deliverables at an estimated cost of $177 million. The type of border and maritime R&D deliverables produced by DHS's Science and Technology (S&T) Directorate, the Coast Guard, and the Domestic Nuclear Detection Office (DNDO) varied, and R&D customers we met with reported mixed views on the impact of the R&D deliverables they received. These deliverables were wide-ranging in their cost and scale, and included knowledge products and reports, technology prototypes, and software (as shown in the figure below). The Coast Guard and DNDO reported having processes in place to collect and evaluate feedback from its customers regarding the results of R&D deliverables. However, S&T has not established timeframes and milestones for collecting and evaluating feedback from its customers on the extent to which the deliverables it provides to DHS components--such as US Customs and Border Protection (CBP)--are meeting its customer's needs. Doing so could help S&T better determine the usefulness and impact of its R&D projects and deliverables and make better-informed decisions …

A letter report issued by the Government Accountability Office with an abstract that begins "Since fiscal year 2008, U.S. agencies allocated over $1.2 billion in funding for Central America Regional Security Initiative (CARSI) activities and non-CARSI funding that supports CARSI goals. As of June 1, 2013, the Department of State (State) and the United States Agency for International Development (USAID) obligated at least $463 million of the close to $495 million in allocated funding for CARSI activities, and disbursed at least $189 million to provide partner countries with equipment, technical assistance, and training to improve interdiction and disrupt criminal networks. Moreover, as of March 31, 2013, U.S. agencies estimated that they had allocated approximately $708 million in non-CARSI funding that supports CARSI goals, but data on disbursements were not readily available. U.S. agencies, including State, the Department of Defense (DOD), and the Department of Justice, use this funding to provide equipment, technical assistance, and training, as well as infrastructure and investigation assistance to partner countries. For example, DOD allocated $25 million in funding to help Guatemala establish an interagency border unit to combat drug trafficking."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) carries out a variety of programs and activities abroad within its areas of expertise that could have the effect of thwarting terrorists and their plots while also combating other categories of transnational crime, and DHS expended approximately $451 million on programs and activities abroad in fiscal year 2012. For example, through the Visa Security Program, DHS has deployed personnel abroad to help prevent the issuance of visas to people who might pose a threat. As of May 2013, DHS has stationed about 1,800 employees in almost 80 countries to conduct these and other activities. In addition, DHS has delivered training and technical assistance in areas such as border and aviation security to officials from about 180 countries to enhance partner nations' security capacities."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has improved its methodology for estimating and comparing the full cost to the taxpayer of work performed by military and civilian personnel and contractor support, but the methodology continues to have certain limitations. Best practices state that cost estimating rules should include a common set of standards that minimize conflicts in definitions, but DOD's methodology does not provide guidance for certain costs. For instance, its estimate of service training costs divides total training funding by the number of servicemembers. Using this method yields an average training cost of $6,490 per servicemember in the Army for fiscal year 2012. However, Army data show that training for a general aviation officer can be as high as $93,600 a year, while the training for an enlisted infantryman can be as low as about $4,600 a year. DOD's Cost Assessment and Program Evaluation (CAPE) office has not provided more specific direction on training costs, although some officials have requested it. Additionally, CAPE officials told GAO they did not include Reserve and National Guard personnel in the methodology because usually these personnel are used on a …

Testimony issued by the Government Accountability Office with an abstract that begins "Performance audits as well as traditional financial and compliance audits are essential tools that national audit offices have to help their respective governments identify and address challenging national and global problems. Performance auditing provides objective analysis so that management and those charged with governance and oversight can use the information to improve program performance and operations, reduce costs, facilitate decision making by parties with responsibility to oversee or initiate corrective action, and contribute to public accountability."

A letter report issued by the Government Accountability Office with an abstract that begins "No overarching federal privacy law governs the collection and sale of personal information among private-sector companies, including information resellers. Instead, a variety of laws tailored to specific purposes, situations, or entities governs the use, sharing, and protection of personal information. For example, the Fair Credit Reporting Act limits the use and distribution of personal information collected or used to help determine eligibility for such things as credit or employment, but does not apply to information used for marketing. Other laws apply specifically to health care providers, financial institutions, videotape service providers, or to the online collection of information about children."

A letter report issued by the Government Accountability Office with an abstract that begins "Nearly half of the Office of Community Oriented Policing Services (COPS) Hiring Program (CHP) funding from fiscal years 2008 through 2012 was awarded to grantees in six states, and award amounts varied considerably in certain years. During this period, state, county, and city law enforcement agencies nationwide received CHP grant awards to hire or rehire officers to advance community policing, with 48 percent of the funds awarded to grantees in California, Florida, Michigan, New Jersey, Ohio, and Texas. For grantees awarded the same number of officers, differences were driven mainly by variation across grantees' respective entry-level officer salaries and benefits. Variation in grantee award amounts were more prominent during 2009, 2010, and 2011, when salary and benefit levels were not statutorily capped, and grantees with higher officer salary and benefit levels generally received more CHP funding relative to other CHP grantees for the same number of officers."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of State (State) and the Department of Defense (DOD) provide guidance to address the Leahy laws, but State's guidance for implementing one requirement of the State Leahy law is unclear. State has used a variety of mechanisms to provide guidance to address the Leahy laws, including guidance to address six of seven new procedural requirements added to the State Leahy law in December 2011. State officials anticipate issuing guidance to address the seventh requirement by October 2013. DOD has provided guidance to address the DOD Leahy law through a 2004 Joint Staff message, and DOD officials said DOD personnel also follow State guidance. While State has provided guidance to embassies to address the duty-to-inform requirement of the State Leahy law, officials at six of the eight embassies GAO visited said that they would like additional guidance that clarifies how to implement the requirement. The duty-to-inform requirement directs State to inform the foreign government if funds are withheld under the law and, to the maximum extent practicable, assist the foreign government in bringing those responsible to justice. With clarifying guidance, embassies will be better able …

A parallel computing framework has been developed to use with general-purpose radiation transport codes. The framework was implemented as a C++ module that uses MPI for message passing. It is intended to be used with older radiation transport codes implemented in Fortran77, Fortran 90 or C. The module is significantly independent of radiation transport codes it can be used with, and is connected to the codes by means of a number of interface functions. The framework was developed and tested in conjunction with the MARS15 code. It is possible to use it with other codes such as PHITS, FLUKA and MCNP after certain adjustments. Besides the parallel computing functionality, the framework offers a checkpoint facility that allows restarting calculations with a saved checkpoint file. The checkpoint facility can be used in single process calculations as well as in the parallel regime. The framework corrects some of the known problems with the scheduling and load balancing found in the original implementations of the parallel computing functionality in MARS15 and PHITS. The framework can be used efficiently on homogeneous systems and networks of workstations, where the interference from the other users is possible.

Prior to processing a Sludge Batch (SB) in the Defense Waste Processing Facility (DWPF), flowsheet studies using simulants are performed. Typically, the flowsheet studies are conducted based on projected composition(s). The results from the flowsheet testing are used to 1) guide decisions during sludge batch preparation, 2) serve as a preliminary evaluation of potential processing issues, and 3) provide a basis to support the Shielded Cells qualification runs performed at the Savannah River National Laboratory (SRNL). SB8 was initially projected to be a combination of the Tank 40 heel (Sludge Batch 7b), Tank 13, Tank 12, and the Tank 51 heel. In order to accelerate preparation of SB8, the decision was made to delay the oxalate-rich material from Tank 12 to a future sludge batch. SB8 simulant studies without Tank 12 were reported in a separate report.1 The data presented in this report will be useful when processing future sludge batches containing Tank 12. The wash endpoint target for SB8 was set at a significantly higher sodium concentration to allow acceptable glass compositions at the targeted waste loading. Four non-coupled tests were conducted using simulant representing Tank 40 at 110-146% of the Koopman Minimum Acid requirement. Hydrogen was generated during …

Warm, liquid clouds and their representation in climate models continue to represent one of the most significant unknowns in climate sensitivity and climate change. Our project combines ARM observations, LES modeling, and satellite imagery to characterize shallow clouds and the role of aerosol in modifying their radiative effects.

As wind generation grows, its influence on power system performance will becoming increasingly noticeable. Wind generation di#11;ffers from traditional forms of generation in numerous ways though, motivating the need to reconsider the usual approaches to power system assessment and performance enhancement. The project has investigated the impact of wind generation on transient stability and voltage control, identifying and addressing issues at three distinct levels of the power system: 1) at the device level, the physical characteristics of wind turbine generators (WTGs) are quite unlike those of synchronous machines, 2) at the wind-farm level, the provision of reactive support is achieved through coordination of numerous dissimilar devices, rather than straightforward generator control, and 3) from a systems perspective, the location of wind-farms on the sub-transmission network, coupled with the variability inherent in their power output, can cause complex voltage control issues. The project has sought to develop a thorough understanding of the dynamic behaviour of type-3 WTGs, and in particular the WECC generic model. The behaviour of such models is governed by interactions between the continuous dynamics of state variables and discrete events associated with limits. It was shown that these interactions can be quite complex, and may lead to switching …

Savannah River Remediation (SRR) has requested that Savannah River National Laboratory (SRNL) characterize a sample of Tank 13 in preparation for Sludge Batch 9 (SB9). A 200 mL sample of Tank 13 was received by SRNL on July 22, 2013 (Tank Farm sample ID HTF-13-13-128). Characterization of the sample to meet the requirements of the request is complete. Results include: visual observations; slurry and supernatant density; weight percent total and insoluble solids; supernatant characterization; total alpha, total beta, and several radionuclide analyses; and elemental analyses of the dried solids. The sample was very fluid. After settling overnight, there was a small layer of solids on the bottom of the sample container (a 250 mL HDPE bottle) with the remainder being clear supernatant. To better show the sludge solids relative to the overall sample, 25 mL of slurry was placed in a graduated cylinder and allowed to settle over a weekend (approximately 90 hours). The sludge layer was at the approximately 4 mL. The small visually observed quantity of insoluble solids was confirmed with a low weight percent insoluble solids of 0.94%.

The major goals of this program were to study the efficacy of low dose rate radiation exposures for the induction of acute myeloid leukemia (AML) and to characterize the leukemias that are caused by radiation exposures at low dose rate. An irradiator facility was designed and constructed that allows large numbers of mice to be irradiated at low dose rates for protracted periods (up to their life span). To the best of our knowledge this facility is unique in the US and it was subsequently used to study radioprotectors being developed for radiological defense (PLoS One. 7(3), e33044, 2012) and is currently being used to study the role of genetic background in susceptibility to radiation-induced lung cancer. One result of the irradiation was expected; low dose rate exposures are ineffective in inducing AML. However, another result was completely unexpected; the irradiated mice had a very high incidence of hepatocellular carcinoma (HCC), approximately 50%. It was unexpected because acute exposures are ineffective in increasing HCC incidence above background. This is a potential important finding for setting exposure limits because it supports the concept of an 'inverse dose rate effect' for some tumor types. That is, for the development of some tumor …

This project provides the first demonstration of the application of proton deflectometry for the diagnosis of electromagnetic field topology and current-carrying regions in Z-pinch plasma experiments. Over the course of this project several milestones were achieved. High-energy proton beam generation was demonstrated on the short-pulse high-intensity Leopard laser, (10 Joules in ~350 femtoseconds, and the proton beam generation was shown to be reproducible. Next, protons were used to probe the electromagnetic field structure of short circuit loads in order to benchmark the two numerical codes, the resistive-magnetohydrodynamics (MHD) code, Gorgon, and the hybrid particle-in-cell code, LSP for the interpretation of results. Lastly, the proton deflectometry technique was used to map the magnetic field structure of pulsed-power-driven plasma loads including wires and supersonic jets formed with metallic foils. Good agreement between the modeling and experiments has been obtained. The demonstrated technique holds great promise to significantly improve the understanding of current flow and electromagnetic field topology in pulsed power driven high energy density plasmas. Proton probing with a high intensity laser was for the first time implemented in the presence of the harsh debris and x-ray producing z-pinch environment driven by a mega-ampere-scale pulsed-power machine. The intellectual merit of the program …
