  • 52031.通过定制捕光系统提高生物太阳能制氢和太阳能的开发的设计固态流程

    [汽车制造业] [2014-07-20]

    This report will provide a final summary of project accomplishments, emphasizing those of approximately the past year of the project. Annual reports previously submitted to AFOSR are incorporated herein by reference. Most recently, we used DNA microarray analyses to characterize stress responses of wild-type Synechocystis sp. PCC 6803 cells encapsulated in different gel formulations. We also characterized photosynthetic activity, encapsulation protocols, and hydrogen production from photoantennae mutants of Synechocystis sp. PCC 6803.In addition, we continued exploring the diffusion of dissolved ions encapsulated in silica gel.

  • 52032.电动汽车充电基础设施部署的基于代理的信息系统

    [信息传输、软件和信息技术服务业,汽车制造业] [2014-07-20]

    The current scarcity of public charging infrastructure is one of the major barriers to mass household adoption of plug-in electric vehicles (PEVs). Although most PEV drivers can recharge their vehicles at home, the limited driving range of the vehicles restricts their usefulness for long-distance travel. In this paper, an agent-based information system is presented for identifying patterns in residential PEV ownership and driving activities to enable strategic deployment of new charging infrastructure. Driver agents consider their own driving activities within the simulated environment, in addition to the presence of charging stations and the vehicle ownership of others in their social network, when purchasing a new vehicle. Aside from conventional vehicles, drivers may select among multiple electric alternatives, including two PEV options. The Chicagoland area is used as a case study to demonstrate the different deployment scenarios are analyzed.

  • 52033.CNG汽车的基于BP神经网络的注气控制

    [汽车制造业] [2014-07-20]

    Compressed natural gas (CNG) automobile is an emerging new energy car.How to control gas injection is the key technology of CNG electronic control system.At present,the control based on the MAP graph is used usually,but this control method has some shortages,for example larger data,poor adaptive capacity and difficulties in data updating.BP neural network control has adaptive and self-learning,nonlinear processing ability and high generalization,and faults tolerant ability in processing information.In this paper,BP neural network is used to control natural gas injection in order to solve the shortage of the MAP picture control.Simulation experiment shows thefeasibility and advantage of this method.

  • 52034.燃料电池型多功能车的分布式氢气供应

    [汽车制造业] [2014-07-20]

    The Energy & Environmental Research Center (EERC) has developed a high-pressure hydrogen production system that reforms a liquid organic feedstock and water at operating pressures up to 800 bar (approx. 12,000 psig). The advantages of this system include the elimination of energy-intensive hydrogen compression, a smaller process footprint, and the elimination of gaseous or liquid hydrogen transport. This system could also potentially enable distributed hydrogen production from centralized coal. Processes have been investigated to gasify coal and then convert the syngas into alcohol or alkanes. These alcohols and alkanes could then be easily transported in bulk to distributed high-pressure water-reforming (HPWR)-based systems to deliver hydrogen economically. The intent of this activity was to utilize the EERC's existing HPWR hydrogen production process, previously designed and constructed in a prior project phase, as a basis to improve operational and production performance of an existing demonstration unit. Parameters to be pursued included higher hydrogen delivery pressure, higher hydrogen production rates, and the ability to refill within a 5-minute time frame.

  • 52039.我国专用汽车发展现状与建议

    [汽车制造业] [2014-07-18]

    按照国家标准GB/T17350-2009(《专用汽车和专用挂车术语代号和编制方法》),专用汽车是指装备有专用设备,具备专用功能,用于承担专门运输任务或专项作业以及其他专项用途的汽车。按结构特征可分为:厢式汽车、罐式汽车、专用自卸汽车、仓栅式汽车、起重举升汽车、特种结构汽车六大类。作为衡量国民经济和汽车工业发展水平的重要标志,自20世纪60年代起,我国的专用汽车经历了从无到有、从弱到强的发展过程。目前,专用汽车已经广泛服务于交通、城建、环卫、市政、军工等国民经济的各个领域,在汽车工业和国民经济中占有举足轻重的地位。专用汽车的研发、生产和应用已得到社会的广泛重视,其在提高运输效率、扩大应用领域等方面发挥着极其重要的作用。
