2862.建设环境在运输方面的影响:能源的使用,温室气体的排放,和其他因素
[水利、环境和公共设施管理业] [2014-08-07]
Planning initiatives in many regions and communities aim to reduce transportation energy use, decrease emissions, and achieve related environmental benefits by changing land use. This report reviews and summarizes findings from existing literature on the relationship between the built environment and transportation energy use and greenhouse gas emissions, identifying results trends as well as potential future actions. The indirect influence of federal transportation and housing policies, as well as the direct impact of municipal regulation on land use are examined for their effect on transportation patterns and energy use. Special attention is given to the 'four D' factors of density, diversity, design and accessibility. The report concludes that policy-driven changes to the built environment could reduce transportation energy and GHG emissions from less than 1to as much as 10by 2050, the equivalent of 16-18of present-day urban light-duty-vehicle travel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

2863.海洋和流体动力技术(MHK)仪器仪表,测量和计算机模拟工作坊
[水利、环境和公共设施管理业] [2014-08-07]
A wide spectrum of marine and hydrokinetic technologies are being developed by industry, universities, and national laboratories in the United States and around the globe. Experience gained in the development of renewable energy, aerospace, and automotive technologies shows that sharing and disseminating technical expertise accelerates the pace of technology development and rapidly progresses the industry towards commercial viability. For this exact purpose, the National Renewable Energy Laboratory organized the Marine and Hydrokinetic Technology (MHK) Instrumentation, Measurement, and Computer Modeling Workshop to bring together technical experts from industry, national laboratories, and academia. The workshop goals were to disseminate technical information regarding environmental monitoring, instrumentation and measurements, and computer modeling to the marine energy community, and to collect information to help identify ways to accelerate the development of a commercially viable marine energy industry.

2864.延迟最小化任务处理的信息处理系统
[水利、环境和公共设施管理业] [2014-08-07]
Real-time cyber-physical systems and information processing clusters require system designers to consider the total latency involved in collecting and aggregating data. For example, applications such as wild-fire monitoring require data to be presented to users in a timely manner. However, most models and algorithms for sensor networks have focused on alternative metrics such as energy efficiency. In this paper, we present a new model of sensor network aggregation that focuses on total latency. Our model is flexible and enables users to configure varying transmission and computation time on a node-by-node basis, and thus enables the simulation of complex computational phenomena. In addition, we present results from three tasking algorithms that trade-off local communication for overall latency performance. These algorithms are evaluated in simulated networks of up to 200 nodes.

In August 2011, the NOAA National Ocean Service (NOS) conducted an assessment of the status of ecological condition of soft-bottom habitat and overlying waters of the continental shelf in the northwestern Gulf of Mexico (GOM). The original sampling design included 50 randomly selected sites from the Mississippi River delta to the U.S./Mexican border, representing a total area of 111,162 km2; however, vessel failures and inclement weather precluded sampling at 16 sites in the western-most part of the study region. Sampling was completed at the remaining 34 sites in offshore waters between the Mississippi River delta and Freeport, Texas, representing an estimated 75,591 km2. Field sampling followed standard methods and indicators applied in prior NOAA coastal studies and EPAs Environmental Monitoring and Assessment Program (EMAP) and National Coastal Assessment (NCA). A key feature adopted from these studies was the incorporation of a random probabilistic sampling design. Such a design provides a basis for making unbiased statistical estimates of the spatial extent of ecological condition relative to various measured indicators and corresponding thresholds of concern. Indicators included multiple measures of water quality, sediment quality, and biological condition (benthic fauna, fish tissue contaminant levels).

2866.西北大学清洁催化工艺设施的研究,最终技术报告
[水利、环境和公共设施管理业] [2014-08-07]
Catalytic processes are today practiced on a vast scale to convert basic feedstocks (today largely petroleum, gas, and coal based) into fuels, plastics, agricultural chemicals, pharmaceuticals, foods, paints/coatings, and numerous other materials that underpin our economy and well-being. Catalysts are also used extensively to provide a cleaner environment by treating automotive and industrial (e.g., power plant) exhausts and water-borne effluents. Indeed, it has been estimated that more than 50of the US GDP derives from catalytic processes. In the past several years, it has become apparent that the US energy supply and demand picture has shifted dramatically, and that a major scientific research and development effort must be mounted to maintain US economic leadership and our quality of life. The challenges are to use and convert more abundant, lower cost/lower quality, and more sustainable feedstocks into the products we need with unprecedented energy- and atom-efficiency. The need to develop more efficient, cleaner and greener catalytic processes is grand challenge of national import.

2867.玻璃钢修补材料力学性能的长期监测
[水利、环境和公共设施管理业] [2014-08-07]
Fiber- reinforced polymer composites (FRP) are an attractive repair option for existing concrete structures. CDOT has used this material on some projects, in particular the repair of the Castlewood Canyon Bridge in 2003. Further use of the material is limited by the lack of data about its long-term performance. Laboratory durability studies have indicated that FRP performs well in conditions such as water and salt water baths, but it is difficult to fully capture field environments in the lab. This project evaluated the condition of the FRP on the Castlewood Canyon Bridge through onsite inspection and pull-off tests, and by bringing FRP back to the labs at CSU to test the tensile strength. Conclusions about the FRP condition are limited by the lack of baseline data, but there does appear to be some deterioration over time. This project also considers the influence of deicing agents on FRP properties through laboratory testing that has been initiated. Implementation: Based on results available at this time it is recommended that CDOT monitor the durability of future FRP applications through a more systematic process in which baseline data is collected and maintained and inspections including material testing are conducted at shorter intervals, perhaps every two to three years.
