A letter report issued by the Government Accountability Office with an abstract that begins "From 2000 to 2010, the number of patent infringement lawsuits in the federal courts fluctuated slightly, and from 2010 to 2011, the number of such lawsuits increased by about a third. Some stakeholders GAO interviewed said that the increase in 2011 was most likely influenced by the anticipation of changes in the 2011 Leahy-Smith America Invents Act (AIA), which made several significant changes to the U.S. patent system, including limiting the number of defendants in a lawsuit, causing some plaintiffs that would have previously filed a single lawsuit with multiple defendants to break the lawsuit into multiple lawsuits. In addition, GAO's detailed analysis of a representative sample of 500 lawsuits from 2007 to 2011 shows that the number of overall defendants in patent infringement lawsuits increased by about 129 percent over this period. These data also show that companies that make products brought most of the lawsuits and that nonpracticing entities (NPE) brought about a fifth of all lawsuits. GAO's analysis of these data also found that lawsuits involving software-related patents accounted for about 89 percent of the increase in defendants over this period."

A letter report issued by the Government Accountability Office with an abstract that begins "Over the past several decades, the Army and Marine Corps have increased their use of simulation-based training--simulators and computer-based simulations. Historically, the aviation communities in both services have used simulators to train servicemembers in tasks such as takeoffs, and emergency procedures that could not be taught safely live. In contrast, the services' ground communities used limited simulations prior to 2000. However, advances in technology, and emerging conditions in Iraq and Afghanistan have led to increased use of simulation-based training in the ground forces. For example, in response to increases in vehicle rollovers, both services began using simulators to train servicemembers to safely evacuate vehicles. The services are also collaborating in the development of some simulation-based training devices. For instance, according to Marine Corps officials, the service reused 87 percent of the Army's Homestation Instrumentation Training System's components in its own training system, achieving about $11 million in cost avoidance and saving an estimated 7 years in fielding time. The services are also taking steps to better integrate live and simulation-based training, developing technical capabilities to connect previously incompatible simulation-based training devices. The Army's capability is now …

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Department of Agriculture (USDA) has not thoroughly evaluated the performance of each of the pilot projects over time even though the agency stated it would do so when it announced the pilot projects. For example, in 2011, USDA completed a report evaluating the pilot project at 20 young chicken plants concluding that an inspection system based on the pilot project would ensure equivalent, if not better, levels of food safety and quality than currently provided at plants not in the pilot project. However, among the limitations of its evaluation was the use of snapshots of data for two 2-year periods instead of data for the duration of the pilot project, which has been ongoing for more than a decade. In addition, USDA did not complete an evaluation on or prepare a report evaluating the pilot project at 5 young turkey plants and has no plans to do so because of the small sample size. Nevertheless, in publishing a proposed rule that includes an optional new poultry (chicken and turkey) inspection system, USDA stated that the new system was based on its experience with the …

A letter report issued by the Government Accountability Office with an abstract that begins "Officials GAO interviewed inside and outside of the Internal Revenue Service (IRS) generally agreed on the potential major benefits of the Compliance Assurance Process (CAP) to taxpayers and IRS as reflected in its goals. These goals include saving IRS time and resources to use for other audits while ensuring compliance, and reducing taxpayer burden while increasing certainty on tax amounts now owed."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Aviation Administration (FAA) has made some progress in addressing key challenges as it begins the gradual transition to the Next Generation Air Transportation System (NextGen). It has filled key leadership positions and developed tools to manage interdependent NextGen programs. FAA is working to address other identified challenges, including incentivizing aircraft operators to equip with NextGen technologies, identifying workforce roles under NextGen, and realigning and consolidating facilities. However, FAA has yet to make some decisions needed to move forward with these efforts. For example, FAA is evaluating realignment options to help realize efficiencies but has not yet identified which facilities will be consolidated or realigned."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2011, the Army has conducted five Network Integration Evaluations (NIE), which have provided extensive information and insights into current network capabilities and potential solutions to fill network capability gaps. According to senior Department of Defense (DOD) test officials, the NIE objective to test and evaluate network components together in a combined event is sound, as is the opportunity to reduce overall test and evaluation costs by combining test events. Further, the NIEs offer the opportunity for a more comprehensive evaluation of the broader network instead of piecemeal evaluation of individual network components. However, the Army is not taking full advantage of the potential knowledge that could be gained from the NIEs, and some resulting Army decisions are at odds with knowledge accumulated during the NIEs. For example, despite poor results in developmental testing, the Army moved forward to operational testing for several systems during the NIEs and they demonstrated similarly poor results. Yet the Army plans to buy and field several of these systems. Doing so increases the risk of poor performance in the field and the need to correct and modify deployed equipment. On …

The overall objective of this project was to develop and fabricate a multifunctional cathode with high activities in acidic electrolytes for the oxygen reduction and evolution reactions for Li-air batteries. It should enable the development of Li-air batteries that operate on hybrid electrolytes, with acidic catholytes in particular. The use of hybrid electrolytes eliminates the problems of lithium reaction with water and of lithium oxide deposition in the cathode with sole organic electrolytes. The use of acid electrolytes can eliminate carbonate formation inside the cathode, making air breathing Li-air batteries viable. The tasks of the project were focused on developing hierarchical cathode structures and bifunctional catalysts. Development and testing of a prototype hybrid Li-air battery were also conducted. We succeeded in developing a hierarchical cathode structure and an effective bifunctional catalyst. We accomplished integrating the cathode with existing anode technologies and made a pouch prototype Li-air battery using sulfuric acid as catholyte. The battery cathodes contain a nanoscale multilayer structure made with carbon nanotubes and nanofibers. The structure was demonstrated to improve battery performance substantially. The bifunctional catalyst developed contains a conductive oxide support with ultra-low loading of platinum and iridium oxides. The work performed in this project has been …

The ability of water managers to maintain adequate supplies in coming decades depends, in part, on future weather conditions, as climate change has the potential to alter river flows from their current values, possibly rendering them unable to meet demand. Reliable climate projections are therefore critical to predicting the future water supply for the United States. These projections cannot be provided solely by global climate models (GCMs), however, as their resolution is too coarse to resolve the small-scale climate changes that can affect hydrology, and hence water supply, at regional to local scales. A process is needed to ‘downscale’ the GCM results to the smaller scales and feed this into a surface hydrology model to help determine the ability of rivers to provide adequate flow to meet future needs. We apply a statistical downscaling to GCM projections of precipitation and temperature through the use of a scaling method. This technique involves the correction of the cumulative distribution functions (CDFs) of the GCM-derived temperature and precipitation results for the 20{sup th} century, and the application of the same correction to 21{sup st} century GCM projections. This is done for three meteorological stations located within the Coosa River basin in northern Georgia, …

The long-range goal of several past and current projects in our DOE-supported research has been the development of new and improved parameterizations of cloud-radiation effects and related processes, using ARM data, and the implementation and testing of these parameterizations in global models. The main objective of the present project being reported on here has been to develop and apply advanced statistical techniques, including Bayesian posterior estimates, to diagnose and evaluate features of both observed and simulated clouds. The research carried out under this project has been novel in two important ways. The first is that it is a key step in the development of practical stochastic cloud-radiation parameterizations, a new category of parameterizations that offers great promise for overcoming many shortcomings of conventional schemes. The second is that this work has brought powerful new tools to bear on the problem, because it has been a collaboration between a meteorologist with long experience in ARM research (Somerville) and a mathematician who is an expert on a class of advanced statistical techniques that are well-suited for diagnosing model cloud simulations using ARM observations (Shen).

The research conducted in this work package is aimed at taking advantage of the long term thermodynamic stability of crystalline ceramics to create more durable waste forms (as compared to high level waste glass) in order to reduce the reliance on engineered and natural barrier systems. Durable ceramic waste forms that incorporate a wide range of radionuclides have the potential to broaden the available disposal options and to lower the storage and disposal costs associated with advanced fuel cycles. Assemblages of several titanate phases have been successfully demonstrated to incorporate radioactive waste elements, and the multiphase nature of these materials allows them to accommodate variation in the waste composition. Recent work has shown that they can be produced from a melting and crystallization process. The objective of this report is to explore the phase formation and microstructural differences between lab scale melt processing in varying gas environments with alternative densification processes such as Hot Pressing (HP) and Spark Plasma Sintering (SPS). The waste stream used as the basis for the development and testing is a simulant derived from a combination of the projected Cs/Sr separated stream, the Trivalent Actinide - Lanthanide Separation by Phosphorous reagent Extraction from Aqueous Komplexes (TALSPEAK) …

The Waste Acceptance Product Specifications (WAPS) 1.2 require that “The Producer shall report the inventory of radionuclides (in Curies) that have half-lives longer than 10 years and that are, or will be, present in concentrations greater than 0.05 percent of the total inventory for each waste type indexed to the years 2015 and 3115”. As part of the strategy to comply with WAPS 1.2, the Defense Waste Processing Facility (DWPF) will report for each waste type, all radionuclides (with half-lives greater than 10 years) that have concentrations greater than 0.01 percent of the total inventory from time of production through the 1100 year period from 2015 through 3115. The initial listing of radionuclides to be included is based on the design-basis glass as identified in the Waste Form Compliance Plan (WCP) and Waste Form Qualification Report (WQR). However, it is required that this list be expanded if other radionuclides with half-lives greater than 10 years are identified that may meet the greater than 0.01% criterion for Curie content. Specification 1.6 of the WAPS, International Atomic Energy Agency (IAEA) Safeguards Reporting for High Level Waste (HLW), requires that the ratio by weights of the following uranium and plutonium isotopes be reported: …

A marine and hydrokinetic (MHK) tidal turbine extracts energy from tidal currents, providing clean, sustainable electricity generation. In general, all MHK conversion technologies are confronted with significant operational hurdles, resulting in both increased capital and operations and maintenance (O&M) costs. To counter these high costs while maintaining reliability, MHK turbine designs can be simplified. Prior study found that a tidal turbine could be cost-effectively simplified by removing blade pitch and rotor/nacelle yaw. Its rotor would run in one direction during ebb and then reverse direction when the current switched to flood. We dubbed such a turbine a bidirectional rotor tidal turbine (BRTT). The bidirectional hydrofoils of a BRTT are less efficient than conventional hydrofoils and capture less energy, but the elimination of the pitch and yaw systems were estimated to reduce levelized cost of energy by 7.8%-9.6%. In this study, we investigated two mechanisms for recapturing some of the performance shortfall of the BRTT. First, we developed a novel set of hydrofoils, designated the yy series, for BRTT application. Second, we investigated the use of active flow control via microtabs. Microtabs are small deployable/retractable tabs, typically located near the leading or trailing edge of an air/hydrofoil with height on the …
