272.月球通信卫星和服务器的设计和实现以应对2012年SISO攻击波
[计算机、通信和其他电子设备制造业,铁路、船舶、航空航天和其他运输设备制造业,信息传输、软件和信息技术服务业] [2014-03-31]
Last year, the Simulation Interoperability Standards Organization (SISO) inaugurated the now annual High Level Architecture (HLA) Smackdown at the Spring Simulation Interoperability Workshop (SIW). A primary objective of the Smackdown event is to provide college students with hands-on experience in the High Level Architecture (HLA). The University of Alabama in Huntsville (UAHuntsville) fielded teams in 2011 and 2012.This paper concentrates on the first two federates by describing the functions, algorithms, the modular FOM, experiences, lessons learned and recommendations for future Smackdown events.

273.使用PSO的自主式移动机器人的1型和2型模糊控制器的隶属函数优化
[电气机械和器材制造业] [2014-03-28]
This paper describes the application of the optimization algorithm based on particle swarms known by its acronym as PSO, used to adjust the parameters of membership functions of a fuzzy logic controller (FLC) to find the optimal intelligent control for a wheeled autonomous mobile robot. Results of several simulations show that the PSO is able to optimize the type-1 and type 2 FLCs for this specific application.

274.基于人工神经网络之反向传播算法的50A1300钢铁热变形流变应力的预测
[黑色金属冶炼和压延加工业] [2014-03-27]
The researches of non-oriented silicon steel are mainly focused on the effect of main processing parameters on the microstructure and magnetic properties,but there have been few studied about its flow stress until now.In this paper,the hot deformation of non-oriented silicon steel 50A1300 is studied by thermal-mechanical simulation method.The hot deformation behavior of the steel is explored and the flow stress prediction of the steel is established based on a kind of BPA ANN.A piecewise method is proposed in this paper,and the prediction with this new method has good accuracy.

275.SBIR第二期项目的技术支持：采用双重生物反应器系统转化纤维素废弃物为乙醇方法的改进.合作研究与开发，最终报告.CRADA编号：CRD-08-310
[电力、热力、燃气及水生产和供应业] [2014-03-27]
Problems in enzymatic conversion of biomass to sugars include the use of incomplete synergistic enzymes, end-product inhibition, and adsorption and loss of enzymes necessitating their use in large quantities. Technova Corporation will develop a defined consortium of natural microorganisms that will efficiently break down biomass to energy-rich soluble sugars, and convert them to cleaner-burning ethanol fuel. The project will also develop a novel biocatalytic hybrid reactor system dedicated to this bioprocess, which embodies recent advances in nanotechnology. NREL will participate to develop a continuous fermentation process.

276.长期议题（2012）：农民的选择与生物燃料的未来
[农、林、牧、渔业,电力、热力、燃气及水生产和供应业] [2014-03-26]
This paper focuses on the patterns of farmers choices regarding dedicated perennial lignocellulosic energy crops. Throughout this paper we use the term perennial as shorthand for warm season grasses such as those in the genus Panicum or Miscanthus, or short rotation tree crops such as those in the genus Populus or Salix. We focus on choices about these perennial crops because two thirds of the mandated advanced biofuels are expected to be converted at biorefineries from perennials (USDA 2010). RFS2 establishes the goals, but not mechanisms for achieving them. Mechanisms and incentives, however, are embedded in other legislation and programs.

277.生物气燃料电池研讨会总结报告（2012.6.11——2012.6.13）
[电力、热力、燃气及水生产和供应业] [2014-03-26]
The National Renewable Energy Laboratory (NREL), held a Biogas and Fuel Cells Workshop on June 11-13, 2012, in Golden, Colorado, to discuss biogas and waste-to-energy technologies for fuel cell applications. The meeting was spearheaded by the Fuel Cell Technologies Program in coordination with the Biomass Program. The overall objective was to identify opportunities for coupling renewable biomethane with highly efficient fuel cells to produce electricity; heat; combined heat and power (CHP); or combined heat, hydrogen and power. The workshop focused on biogas sourced from wastewater treatment plants (WWTPs), landfills, and industrial facilities that generate or process large amounts of organic waste, including large biofuel production facilities (biorefineries).

278.使用加氢热解和加氢转化技术将生物质转化为汽油和柴油的研究（报告期：2010.4.1——2012.12.1）
[电力、热力、燃气及水生产和供应业] [2014-03-26]
These studies show when using IH2 technology, biomass can be converted directly to transportation quality fuel blending components for the same capital cost required for pyrolysis alone, and a fraction of the cost of pyrolysis plus upgrading of pyrolysis oil. Technoeconomic work for IH2 and lifecycle analysis (LCA) work has also been completed as part of this DOE study and shows IH2 technology can convert biomass to gasoline and diesel blending components for less than $2.00/gallon with greater than 90reduction in greenhouse gas emissions. As a result of the work completed in this DOE project, a joint development agreement was reached with CRI Catalyst Company to license the IH2 technology.

280.利用奶牛和肉牛畜牧生产的可再生能源及环境的可持续发展.卷1：热化学转化与直接燃烧法
[电力、热力、燃气及水生产和供应业] [2014-03-26]
Manure-based biomass (MBB) has the potential to be a source of green energy at large coal-fired power plants and on smaller-scale combustion systems at or near confined animal feeding operations. Although MBB particularly cattle biomass (CB) is a low quality fuel with an inferior heat value compared to coal and other fossil fuels, the concentration of it at large animal feeding operations can make it a viable source of fuel. The overall objective of this interdisciplinary proposal is to develop environmentally benign technologies to convert low-value inventories of dairy and beef cattle biomass into renewable energy. Current research expands the suite of technologies by which cattle biomass (CB: manure, and premature mortalities) could serve as a renewable alternative to fossil fuel.
