    Rail residual stress distributions can be complex and variable in nature, as different manufacturing techniques produce varying stress magnitudes and distributions. To evaluate the effect of residual stresses on rail integrity, an analysis technique was sought that could quantify the effect of these stresses on web crack propagation.

    The computer program LS-DYNA3D was used to simulate the behavior of a specific, though representative, heavy truck cab-over tractor-trailer vehicle during a full 180° rollover event. These simulations provide a key component in the development of a physical testing procedure for evaluating structural integrity and occupant crash protection system designs in heavy trucks.

    Recent changes in the utilities in California, particularly the surplus of solar generated electricity during the afternoon periods, is causing the utilities in the state to request significant changes in their long established Time-of-Use (TOU) periods. The utilities are proposing changing the on-peak TOU period from the long standing afternoon period in the summer to the evening hours and, in many cases, extending the on-peak from the summer season to year around (see Table 1).

    Water in the U.S. is a huge energy user. Approximately 4 perecent of all electricity consumed in the U.S. is used to deliver water and treat wastewater, more than is consumed by the pulp, paper, and petroleum industries. In California water related energy use consumes 19 percent of the state's electricity, 30 percent of its natural gas, and 88 billion gallons of diesel fuel every year. And it is only going to get worse, a lot worse, as the water community struggles to find adequate supplies of water to satisfy a growing population, tries to find ways to treat water to remove ever increasingly miniscule amounts of known pollutants, and tries to cope with a bewildering array of newly identified contaminants.

    This article provides a brief comparison of the public sector vs. private sector in terms of characteristics, applicable incentives, and decision- making criteria for participating in new, untried endeavors like demand-side programs, using water agencies in California as the public sector example. Recommendations on characteristics of utility demandside programs likely to be attractive to public agencies are provided.

    Water utilities are facing a number of issues: droughts and climatic variations in water supply, rapidly rising operating costs, demands for increasingly expensive investments in treatment for fresh water and wastewater, heightened customer expectations in both service and environmental impacts, and the need to replace aging infrastructure. This has spurred interest among water suppliers in managing water demand, capturing all revenue, minimizing distribution system and customer water losses, and increasing customer support and information. A change in their metering systems is one of the primary tools to do this.

    11/30/2016 · Energy - Utilities
    Smart meters have been prominent in the energy utility world, and are beginning to make substantial inroads in the water utility world. Smart meters are probably more useful for the water sector than for the energy sector, and the old days of billing total water consumption during the last month or two is being phased out with the introduction of time-of-use water consumption information. Smart meter installations have reported numerous benefits, both operational and on the customer side (see Table 1). Aside from the obvious savings from reduced need for onsite meter reading, the ability to identify not just the volume of water consumption but also the timing of that consumption has significant benefits, particularly to customers, and may be a linchpin for enhanced water conservation efforts.

    10/25/2016 · Energy - Utilities
    One of the state of California's largest end uses of electricity is in the treatment, heating and cooling, and conveyance of water. In 2005, the California Energy Commission estimated that water-related energy accounts for almost 20% of the state's electricity requirements. The California Public Utilities Commission (CPUC) followed this observation by authorizing water-energy pilot projects designed to validate claims that saving water can save energy and explore whether energy savings may be realized through water conservation measures and incorporated into electric utility energy efficiency programs (http://www.cpuc.ca.gov/PUC/energy/Energy+Efficiency/Water+Energy+Nexus+Programs.htm).
