  • 162061.电迁移域汽车2电网标准

    [电力、热力、燃气及水生产和供应业] [2014-07-18]

    The domain of electromobility extends the topic of the Smart Grid by another large consumer, but also adds storage possibilities. Therefore it is necessary to create a new infrastructure of loading points. The communication is not limited between loading points and the vehicle, but there is also a communication between loading point and the distribution network. Additionally there are many different scenarios possible, whereas the loading point also communicates with EMS/DMS. These chapter addresses the aforementioned points and give further information and possible solutions in terms of communication standards

  • 162062.机器人在太空探索的可行性

    [信息传输、软件和信息技术服务业] [2014-07-18]

    Robots in extraterrestrial exploration traditionally faced difficulties in surface landings and flexible locomotion. Our project explored the viability of building robots around the tensegrity structural concept, which allows greater shock absorbance and flexibility by using isolated components held together through continuous tension. The study was separated into two parts: a physical prototype of a Super Ball tensegrity robot to test manufacturing viability and impact resilience in combination with a software simulation model to test control strategies and design concepts, such as position and number of actuators. This paper focused on the robustness of using software simulation models to predict the behavior of complex physical structures, such as the Super Ball tensegrity robot. Results included controlled locomotion simulations from a custom framework built on top of Bullet, a real-time physics simulation software, and initial rolling movement with a physical prototype. Software simulation models provided useful results for preliminary viability assessments, but should not replace physical prototyping, especially for complex structures. In conclusion, tensegrity robots could become promising alternatives to traditional rigid robots, which are more fragile and less flexible.

  • 162063.智能电网的需求工程

    [电力、热力、燃气及水生产和供应业] [2014-07-18]

    Within this chapter requirements engineering methods and models in context of Smart Grid development are outlined. First, the activities of requirements engineering and their integration into superordinate process models are introduced. Subsequently, the layered models of the GridWise Architectural Council and the Smart Grid Architectural Model (SGAM) are outlined. These cover viewpoints from business requirements to component specification and therefore may be used to structure Smart-Grid-specific requirements engineering activities. The application of the SGAM is illustrated by using the example of the Advanced Metering Infrastructure (AMI). Since the development of Smart Grids represents a long-term engineering effort, this chapter also introduces the concept of technology roadmaps to manage strategic goals and requirements. The assessment of technological and organizational progress in Smart Grid development complements this approach and is subsequently covered by the discussion of the Smart Grid Maturity Model (SGMM). The chapter concludes with a brief summary and references for further reading regarding inputs to the SGAM Layers.

  • 162064.增加饱腹感的饮食策略

    [卫生和社会工作] [2014-07-18]

    Obesity has a multifactorial etiology. Although obesity is widespread and associated with serious health hazards, its effective prevention and treatment have been challenging. Among the currently available treatment approaches, lifestyle modification to induce a negative energy balance holds a particularly larger appeal due to its wider reach and relative safety. However, long-term compliance with dietary modifications to reduce energy intake is not effective for the majority. The role of many individual nutrients, foods, and food groups in inducing satiety has been extensively studied. Based on this evidence, we have developed sample weight-loss meal plans that include multiple satiating foods, which may collectively augment the satiating properties of a meal. Compared to a typical American diet, these meal plans are considerably lower in energy density and probably more satiating. A diet that exploits the satiating properties of multiple foods may help increase long-term dietary compliance and consequentially enhance weight loss.

  • 162066.指导实施宽带电力线通信标准的共存

    [电力、热力、燃气及水生产和供应业] [2014-07-18]

    Power Line Communication (PLC) systems provide a bi-directional communication platform capable of delivering data for a variety of Smart Grid applications such as home energy management and intelligent meter reading and control. One benefit of applying power line communication on power grid is that it provides an infrastructure that is much more comprehensive and widespread than other wired/wireless alternatives. Power line cables are a shared medium, therefore multiple PLC devices operate on the same frequency over the same power line may interfere with each other, thus reducing the effectiveness of these devices. This publication introduces the coexistence mechanism for the IEEE and ITU-T BB-PLC standards, and provides implementation guidelines for PLC devices to be used for smart grid applications.

  • 162067.戒烟服务

    [医药制造业] [2014-07-18]

    Tobacco is a highly addictive substance with well-documented health risks. Although great progress has been made in reducing and preventing tobacco use in the United States, the rates of cigarette use and dependence remain high in certain subpopulations, including those with substance use disorders. For example, 2011 data show that an estimated 22 percent of U.S. adults are current cigarette smokers, whereas smoking prevalence rates for those in substance abuse treatment exceeded 70 percent between 2005 and 2009. The negative health effects of tobacco use among alcohol- and drug dependent individuals can be substantial. Individuals in substance abuse treatment smoke more heavily than the general population, and consequently are more likely to suffer from tobacco-related morbidity, including cardiopulmonary problems, emphysema, and cancer, than are smokers in the general population. One study of substance abuse treatment clients found that tobacco use caused more deaths than the alcohol or drug use that brought them to treatment; specifically, the rate of death among tobacco users was nearly 1.5 times the rate of death from other addiction-related causes.

  • 162070.新型麦芽四糖酶及其应用

    [食品制造业] [2014-07-15]

    麦芽四糖属麦芽低聚糖,与蔗糖相比,它具有低甜度,高粘度,低渗透压,耐强酸等特性,因此在食品行业有特别的应用.目前虽然能够产生麦芽四糖的酶不少,但真正工业化生产的却很少,且被报道的大部分麦芽四糖酶须在中性或偏碱性条件下进行反应,这对实际生产操作带来很多不便,影响产品质量并导致生产成本较高.作者采用一种新型的由嗜糖假单胞菌改造得到的耐热耐酸的麦芽四糖酶,对其生产麦芽四糖的工艺条件进行了研究及优化.实验表明,该酶可以在pH4.0~8.0,温度55~70℃,与普鲁兰酶协同作用生产质量分数在50%以上的麦芽四糖糖浆.
