Hearing Loss Prevention: Improvements to DOD Hearing Conservation Programs Could Lead to Better Outcomes (open access)

Hearing Loss Prevention: Improvements to DOD Hearing Conservation Programs Could Lead to Better Outcomes

A letter report issued by the Government Accountability Office with an abstract that begins "Exposure to hazardous noise can have negative implications for both servicemember health and readiness. Moreover, in fiscal year 2009, some of the most common impairments for veterans receiving Veterans Affairs (VA) disability benefits were hearing related, as annual payments for such conditions exceeded $1.1 billion. To examine Department of Defense (DOD) efforts to prevent hearing loss, GAO is reporting on (1) how well the DOD and armed services identify and mitigate hazardous noise; (2) how well the military evaluates hearing conservation program performance; and (3) the status of DOD's Hearing Center of Excellence and the extent that DOD and VA are sharing information to inform this and other efforts. GAO reviewed DOD and services' policies and guidance, reviewed DOD performance data, interviewed officials and servicemembers, and conducted site visits to nine military bases."

High Efficiency, Low Emissions Homogeneous Charge Compression Ignition (HCCI) Engines (open access)

High Efficiency, Low Emissions Homogeneous Charge Compression Ignition (HCCI) Engines

This is the final report of the High Efficiency Clean Combustion (HECC) Research Program for the U.S. Department of Energy. Work under this co-funded program began in August 2005 and finished in July 2010. The objective of this program was to develop and demonstrate a low emission, high thermal efficiency engine system that met 2010 EPA heavy-duty on-highway truck emissions requirements (0.2g/bhp-hr NOx, 0.14g/bhp-hr HC and 0.01g/bhp-hr PM) with a thermal efficiency of 46%. To achieve this goal, development of diesel homogenous charge compression ignition (HCCI) combustion was the chosen approach. This report summarizes the development of diesel HCCI combustion and associated enabling technologies that occurred during the HECC program between August 2005 and July 2010. This program showed that although diesel HCCI with conventional US diesel fuel was not a feasible means to achieve the program objectives, the HCCI load range could be increased with a higher volatility, lower cetane number fuel, such as gasoline, if the combustion rate could be moderated to avoid excessive cylinder pressure rise rates. Given the potential efficiency and emissions benefits, continued research of combustion with low cetane number fuels and the effects of fuel distillation are recommended. The operation of diesel HCCI was …

Inflow Characterization for Marine and Hydrokinetic Energy Devices. FY-2010 Annual Progress Report

Marine and Hydro Kinetic devices (MHK) are being widely studied as a source of renewable energy. The Marrowstone Island site is a potential location for installing MHK devices because the tidal currents observed that are sufficient for power generation. In order to quantify the effects of turbulence on MHK devices and the surrounding environment at this site, a prelimi- nary fluid flow field study was conducted here by the Pacific Northwest National Lab (PNNL) in collaboration with the Applied Physics Lab at the University of Washington (APL-UW). This study entailed continuous The Acoustic Doppler Velocimetry (ADV), Acoustic Doppler Current Profiler (ADCP) and Conductivity, Temperature and Depth (CTD) measurements from May 4, 2010 to May 22, 2010, in order to obtain information about turbulence effects during different tidal conditions. The instruments used for collecting the above measurements were deployed at the Marrowstone site using a R/V Jack Robertson provided by the University of Washington (APL-UW). All the measurements were taken at the site with an average depth of 22 m below the sea surface. ADV acquired velocity data at 32 Hz sampling frequency at 4.6 m above the seabed, and ADCP acquired velocity profile data at a sampling frequency of 2 …

Medicare: Private Sector Initiatives to Bundle Hospital and Physician Payments for an Episode of Care

Correspondence issued by the Government Accountability Office with an abstract that begins "In recent years, we and other federal fiscal experts--including the Congressional Budget Office (CBO) and the Medicare Trustees--have noted the rise in Medicare spending and expressed concern that the program is unsustainable in its present form. Concerns about the rising cost of health care are particularly pressing in light of evidence that suggests that greater spending does not necessarily translate to better health outcomes or higher-quality care. Medicare's fee-for-service (FFS) payment system may contribute to spending growth because it rewards volume of services regardless of the appropriateness, cost, and quality of those services. Under FFS, a payment is made for each unit of service based on the expected costs of delivering that service. For example, Medicare makes multiple separate payments for the services associated with a complex medical procedure performed in a hospital. It pays the hospital for the initial admission and any related readmissions; each physician involved in the patient's care, such as the surgeon and the anesthesiologist; and the skilled nursing facility for any related care immediately after hospitalization. Payments made in isolation in this way may give providers little incentive to coordinate the provision of …

PowerGrid - A Computation Engine for Large-Scale Electric Networks (open access)

PowerGrid - A Computation Engine for Large-Scale Electric Networks

This Final Report discusses work on an approach for analog emulation of large scale power systems using Analog Behavioral Models (ABMs) and analog devices in PSpice design environment. ABMs are models based on sets of mathematical equations or transfer functions describing the behavior of a circuit element or an analog building block. The ABM concept provides an efficient strategy for feasibility analysis, quick insight of developing top-down design methodology of large systems and model verification prior to full structural design and implementation. Analog emulation in this report uses an electric circuit equivalent of mathematical equations and scaled relationships that describe the states and behavior of a real power system to create its solution trajectory. The speed of analog solutions is as quick as the responses of the circuit itself. Emulation therefore is the representation of desired physical characteristics of a real life object using an electric circuit equivalent. The circuit equivalent has within it, the model of a real system as well as the method of solution. This report presents a methodology of the core computation through development of ABMs for generators, transmission lines and loads. Results of ABMs used for the case of 3, 6, and 14 bus power …

Rail Transit: FTA Programs Are Helping Address Transit Agencies' Safety Challenges, but Improved Performance Goals and Measures Could Better Focus Efforts (open access)

Rail Transit: FTA Programs Are Helping Address Transit Agencies' Safety Challenges, but Improved Performance Goals and Measures Could Better Focus Efforts

A letter report issued by the Government Accountability Office with an abstract that begins "Although transit service is generally safe, recent high-profile accidents on several large rail transit systems--notably the June 2009 collision in Washington, D.C., that resulted in nine fatalities and 52 injuries--have raised concerns. The Federal Transit Administration (FTA) oversees state agencies that directly oversee rail transit agencies' safety practices. FTA also provides assistance to transit agencies, such as funding and training, to enhance safety. GAO was asked to determine (1) the challenges the largest rail transit systems face in ensuring safety and (2) the extent to which assistance provided by FTA addresses these challenges. GAO visited eight large rail transit systems and their respective state oversight agencies, reviewed pertinent documents, and interviewed rail transit safety experts and officials from FTA and the National Transportation Safety Board (NTSB)."

Rail Transit: Reliability of FTA's Rail Accident Database

Correspondence issued by the Government Accountability Office with an abstract that begins "As Congress requested, we conducted a review of challenges associated with enhancing safety on major rail transit systems. During the course of that review, we assessed the quality of data that the Federal Transit Administration (FTA) collects and maintains in its State Safety Oversight (SSO) Rail Accident Database. FTA, an agency within the Department of Transportation (DOT), collects these safety data, including data on types of accidents and causes, from SSO agencies and the rail transit agencies they oversee. FTA used the SSO Rail Accident Database to produce the agency's 2009 Rail Safety Statistics Report, which analyzed data from 2003 through 2008. Although we originally intended to report on safety trends using the SSO Rail Accident Database in the rail transit report, we determined that these data were not sufficiently reliable for such a purpose. As a result, in this review we further assess the SSO Rail Accident Database and FTA's processes for collecting and compiling the data. We determined that there are numerous inaccuracies in FTA's SSO Rail Accident Database and, consequently, the 2009 Rail Safety Statistics Report. FTA implemented changes to the data collection process over …

SHARING AND DEPLOYING INNOVATIVE INFORMATION TECHNOLOGY SOLUTIONS TO MANAGE WASTE ACROSS THE DOE COMPLEX (open access)

SHARING AND DEPLOYING INNOVATIVE INFORMATION TECHNOLOGY SOLUTIONS TO MANAGE WASTE ACROSS THE DOE COMPLEX

There has been a need for a faster and cheaper deployment model for information technology (IT) solutions to address waste management needs at US Department of Energy (DOE) complex sites for years. Budget constraints, challenges in deploying new technologies, frequent travel, and increased job demands for existing employees have prevented IT organizations from staying abreast of new technologies or deploying them quickly. Despite such challenges, IT organizations have added significant value to waste management handling through better worker safety, tracking, characterization, and disposition at DOE complex sites. Systems developed for site-specific missions have broad applicability to waste management challenges and in many cases have been expanded to meet other waste missions. Radio frequency identification (RFID) and global positioning satellite (GPS)-enabled solutions have reduced the risk of radiation exposure and safety risks. New web-based and mobile applications have enabled precision characterization and control of nuclear materials. These solutions have also improved operational efficiencies and shortened schedules, reduced cost, and improved regulatory compliance. Collaboration between US Department of Energy (DOE) complex sites is improving time to delivery and cost efficiencies for waste management missions with new information technologies (IT) such as wireless computing, global positioning satellite (GPS), and radio frequency identification (RFID). …
