On February 18, 2014, President Obama directed the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) to develop a second round of greenhouse gas (GHG) emission and fuel economy standards for medium- and heavy-duty trucks. The standards, which will affect trucks beginning with the 2019 model year, are to be proposed by March 2015 and finalized a year later. The standards will be the fourth set of GHG emission standards for mobile sources.

This report presents results from the 2012 National Occupanst Protection Use Survey (NOPUS) Controlled Inter-section Study. NOPUS is the only nationwide probability-based occupant restraint use survey. The National Center for Statistics and Analysis of the National Highway Traffic Safety Administration conducts this survey annually. The 2012 NOPUS found that male seat belt use increased significantly (up to 84 percent in 2012 from 81 percent in 2011) and that female seat belt use increased significantly (up to 88 percent in 2012 from 86 percent in 2011). Seat belt use among occupants age 25-69 years old increased significantly (up to 87 percent in 2012 from 84 percent in 2011). Restraint use for children in vans and SUVs decreased significantly down to 94 percent in 2012 from 97 percent in 2011. Seat belt use in rear seats stood at 75 percent in 2012.

Depending on the individual school districts, grades are divided into elementary schools (grades K through 5), middle schools (grades 6 through 8), and high schools (grades 9 through 12). Included in the AEDG-K12 are prescriptive recommendations by climate zone for the design of the building envelope, fenestration, lighting systems (including electric lights and daylighting); heating, ventilating, and air-conditioning (HVAC) systems; building automation and controls; outdoor air (OA) treatment; and service water heating (SWH). Additional savings recommendations are also included, but not necessary for the 50% savings goal. These recommendations are provided for additional HVAC strategies and renewable energy systems.

This document provides a set of model protocols for determining energy and demand savings that result from specific energy efficiency measures implemented through state and utility efficiency programs. The methods described here are approaches that areor are amongthe most commonly used in the energy efficiency industry for certain measures or programs. As such, they draw from the existing body of research and best practices for energy efficiency program evaluation, measurement, and verification (EM&V). These protocols were developed as part of the Uniform Methods Project (UMP), funded by the U.S. Department of Energy (DOE). The principal objective for the project was to establish easy-to-follow protocols based on commonly accepted methods for a core set of commonly deployed energy efficiency measures.

The ZEBRAlliance is an opportunity to accelerate progress toward DOE's goal of maximizing cost-effective energy efficiency by investing in a highly leveraged, focused effort to test new ultra-high-efficiency components emerging from ORNL's Cooperative Research and Development Agreement (CRADA) partners and others. The Alliance integrated efficient components into the construction of four research houses that will be used as test markets to gauge the integral success of the components and houses. These four research houses are expected to be the first houses used to field-test several newly emerging products such as the ClimateMaster ground-source integrated heat pump, factory assembled ZEHcor walls, and one or more new appliances from Whirlpool Corporation.

In preparation for a large rehabilitation project on the Anthony Wayne Bridge (AWB), the Ohio Department of Transportation has expressed interest in evaluating monitoring and protection strategies which may extend the life of the AWB. This study was proposed and performed in line with this goal. Corrosion of the main cable was identified as the driving mechanism for the aging of suspension bridges. Experiments were performed in order to determine whether or not the existing acoustic monitoring system on the AWB could be used to readily identify active corrosion. Results from laboratory testing show that use of acoustic emission to detect corrosion is possible and promising; however, field experiments indicate that additional tests are needed to determine the practicality of identifying corrosion in the field. The upcoming bridge closure will provide a great opportunity for researchers to more closely examine this possibility. In addition, this report includes literature investigation into other state-of-theart corrosion monitoring and protection strategies including an internal sensor array, the magnetic main flux method for wire inspection, and cable dehumidification.

Methods:A concentric rings readout trajectory with constant angular velocity is proposed for hyperpolarized 13C spectroscopic imaging and its properties are analyzed. Quantitative analysis of design tradeoffs are presented for several imaging scenarios in terms of resolution, spectral bandwidth, acquisition time and SNR efficiency. Analysis comparing parallel imaging accelerated Cartesian sampling and concentric rings in terms of reconstruction noise amplification are also presented. Finally, the first application on 13C phantoms and in vivo animal hyperpolarized 13C MRSI studies were performed to demonstrate the feasibility of the proposed method.Results:The concentric rings MRSI trajectory has the advantages of acquisition timesaving compared to echo-planar spectroscopic imaging (EPSI), and robustness to system timing delay and eddy currents compared to spiral MRSI. It provides a sufficient spectral bandwidth with a relatively high SNR efficiency compared to EPSI and spiral techniques. It will also be beneficial for parallel imaging by reducing noise amplificiation.

This paper studies conditions where messages endlessly circulate in a system of IEEE 1588-2008 clocks. The study is based on two independent analysis techniques. One uses a discrete event simulation environment for describing the operation of the best master clock (BMC) algorithm in IEEE 1588-2008. The second uses a model checking tool. We discuss several cases illustrating conditions under which circulating messages occur and the effectiveness of measures to squelch these messages. This paper demonstrates that one or more of the squelching mechanisms must be implemented.
