Each year thousands of people get displaced and are forced to live in refugee camps or relief camps because of man-made or natural disasters. These people often lack basic needs such as clean water, lighting, cooling, etc. and many times these camps exist for more than 7–8 years. This paper aims at conceptualizing an Emergency Energy Module (EEM) which provides electrical energy to satisfy the basic needs and that can be deployed as an emergency response in a self-sufficient, self-contained, and highly mobile fashion, to support the energy demand of a refugee or a relief camp and the aid workers for long term. As a case study, a refugee camp near Chad-Sudan border has been investigated. As a preliminary study, electrical demand was determined for the camp. Further, locally available energy resources were studied and assessed based on key design criteria and the technologies were selected to meet the demand. Polycrystalline Solar PV panels, micro wind turbine and biogas polyethylene digester and diesel generator were chosen as the technology to harness selected energy resources. HOMER Software has been used for optimization and techno-economic analysis of the energy system. The selected solution has been, then, analyzed from an operational point of view.
每年都有成千上万的人因为人为或自然灾害而流离失所,被迫住在难民营或救济营。这些人往往缺乏基本需求,如干净的水,照明,冷却等,很多时候这些营地存在超过7-8年。本文旨在构想一种应急能源模块(EEM),该模块提供满足基本需求的电能,可以以自给自足、自成一体和高度机动的方式作为应急响应部署,以长期支持难民或难民营和援助人员的能源需求。作为一个案例研究,对乍得-苏丹边界附近的一个难民营进行了调查。作为初步研究,确定了营地的电力需求。此外,根据关键的设计标准,研究和评估了当地可用的能源资源,并选择了满足需求的技术。多晶太阳能光伏板、微型风力涡轮机、沼气聚乙烯沼气池和柴油发电机被选为利用选定能源的技术。采用HOMER软件对能源系统进行优化和技术经济分析。然后,从操作的角度分析所选的解决方案。

E-commerce is becoming more widespread as its ability being recognize to rapidly respond to requests and as more products and services become available. At the present time, only human beings are able to understand the services and product information published online. This cause unnecessary delay in decision making and increase the efforts of humans. In current e-World agents are replacing humans to perform the same tasks in much smarter ways. They negotiate, decide and perform on behalf of humans. Nevertheless, price is the one of the major criterion by which agents are created. This factor is easy to measure and automate. In this paper, we present an agent based model for B2C e-commerce, which deploys intelligent agents to facilitate autonomous and automatic on-line searching by intelligent agents which quickly responds to customers requests. System rests on 3-tier application and ontology of books and implementation of searching and comparison module to gain the deep perspective of domain. Implementing the architecture for online services, that is, searching the product from online web sites and comparing that product amongst different web sites and getting the result of cheapest price at the run time is our main objective. We analyzed the effectiveness of the model by customer-driven web site which provided information about products in an efficient way. The basic purpose was to satisfy our customers and search the product in cheapest price.
随着越来越多的产品和服务的出现,人们认识到电子商务能够快速响应请求,因此电子商务正变得越来越普遍。目前,只有人类能够理解网上发布的服务和产品信息。这造成了不必要的决策延迟,增加了人类的努力。在当前的电子世界中,代理正在以更智能的方式取代人类执行同样的任务。它们代表人类进行谈判、决策和执行。然而,价格是创造代理人的主要标准之一。这个因素很容易测量和自动化。本文提出了一种基于智能代理的B2C电子商务模型,该模型通过智能代理的部署实现了智能代理的自主、自动在线搜索,智能代理可以快速响应客户的请求。系统基于图书本体的三层应用和搜索比较模块的实现,以获得更深层次的领域视角。实现在线服务的体系结构,也就是说,从在线网站搜索产品,并在不同的网站中比较该产品,并在运行时获得最便宜的价格是我们的主要目标。以客户驱动型网站为例,分析了该模型的有效性。基本目的是让我们的客户满意,并以最便宜的价格搜索产品。

Diesel blended with minor biodiesel has been implemented as an initial act on alternative energy issue worldwide. Biodiesel brings the change of pollutant emissions after a burning process. The surface morphology and biotoxicity comparisons of particulate emitted from diesel and biodiesel blend was carried out using an unmodified four-stroke engine generator. Particulate size distribution was measured using a micro-orifice uniform deposit impactor. The Microtox test and the 3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide (MTT) assay indicate the acute and cell viability, respectively, for the particulate collected in the engine exhaust gas. The results showed that diesel produces more particulate than biodiesel blend as expected, and the light operating load does not favor a particulate reduction. No significant trend was observed between the acute toxicity and engine operating load. The engine optimum operation differed fueling with diesel and B10. Additionally, engine running at a high operating load was observed to reduce the particulate cytotoxicity in the engine exhaust.
在世界范围内,掺加少量生物柴油的柴油已成为解决替代能源问题的初步举措。生物柴油在燃烧过程中带来了污染物排放的变化。使用未经改装的四冲程发动机发电机对柴油和生物柴油混合物排放的颗粒进行了表面形貌和生物毒性比较。采用微孔均匀沉积冲击器测量颗粒尺寸分布。Microtox测试和3-(4,5-二甲基噻唑-2-基)- 2,5-二苯基溴化四唑(MTT)测试分别显示了发动机尾气中收集的颗粒的急性和细胞活力。结果表明,柴油产生的颗粒比混合生物柴油更多,并且轻运行负荷不利于颗粒减少。急性毒性与发动机工作负荷之间无明显变化趋势。柴油机的最佳运行工况不同于柴油机和B10。此外,在高负荷下运行的发动机被观察到可以减少发动机排气中的颗粒细胞毒性。

This paper presents a proposal of sustainable energy indicators for cities. This research presents 26 indicators classified into five dimensions (environmental, economic, social, territorial and political). The indicators were validated by experts of different fields who also gave weights for each indicator depending on its importance to sustainability. This resulted in the finding of key indicators in each dimension. The analysis of these five dimensions could help policymakers to foster sustainable energy development in the cities.

This paper proposes a design of sophisticated multi-Objective H2/H∞ collective pitch controllers using linear Matrix Inequalities' techniques. The proposed controller's design takes into account model uncertainties by designing a controller based on a polytopic model. The LMI-based approach allows additional constraints to be included in the design (e.g. H∞ problem, H2 problem, H∞/H2 trade-off criteria, and pole clustering).These constraints are exploited to include requirements for perfect regulation, efficient disturbance rejection, and permissible actuator usage. The proposed controller is compared to an optimal linear quadratic regulator pitch controller based on single model. Both controllers are tested on 5-MW Reference wind turbine model developed by NREL using FAST software code.

Cloud computing, in spite of a few issues associated with it, is being proposed as the panacea of many IT challenges. The various delivery models of it provide a unique way of sharing resources which was never the case before. The adoption of the various delivery models will in turn help in reducing piracy levels. The health industry which, at present, is plagued by issues like high cost etc is bound to benefit the most. The robotics industry as well can make use of cloud computing in making the robots cheaper, faster, and lighter.
尽管存在一些与之相关的问题,云计算正被认为是解决许多it挑战的灵丹妙药。它的各种交付模式提供了一种前所未有的共享资源的独特方式。采用各种交付模式将反过来有助于减少盗版水平。目前被高成本等问题困扰的健康产业必然是最大的受益者。机器人工业也可以利用云计算使机器人更便宜、更快、更轻。

In present study, the simple test procedure is proposed for thermal performance evaluation of solar dryers in general and mixed mode dryer in particular. Steady state heat balance concept has been applied to the absorber surface of collector-dryer assembly for identification of a dimensionless parameter called Dryer Performance Ratio (DPR) representing the effectiveness of a dryer. No-load experiments on mixed mode dryer have been performed for natural and forced air circulation under indoor controlled conditions. The dryer is tested for a wide range of operating conditions of absorbed thermal energy (300–800W/m2) and air mass flow rate (0.009–0.026 kg/s). Comparison of DPR values obtained for natural and forced air circulations indicates a significant performance improvement of 94% at the minimum air flow rate of 0.009 kg/s. It is also found that there is sharp rise in DPR by 31% is observed when airflow is increased from 0.009 to 0.017 kg/s and thereafter a marginal increase of 4% can be noticed for air flow enhancement of ∼ 53%. Another important finding of present study relates to invariable DPR values obtained for a wide range of absorbed energy and ambient air temperature data irrespective of air circulation mode adopted for a dryer.
本文提出了一种简单的太阳能干燥机热性能评价方法,并对混合模式干燥机的热性能进行了评价。稳态热平衡概念已应用于集热器-干燥器组件的吸收器表面,用于识别称为干燥器性能比(DPR)的无量纲参数,代表干燥器的有效性。在室内可控条件下,对混合式干燥机进行了自然和强制空气循环的空载试验。该干燥机在吸收热能(300-800W /m2)、空气质量流量(0.009-0.026 kg/s)的大范围工况下进行了测试。比较自然和强制空气循环的DPR值表明,在最小空气流速为0.009 kg/s时,性能显著提高94%。还发现,当气流从0.009 kg/s增加到0.017 kg/s时,DPR急剧上升31%,此后,当气流增强~ 53%时,可以注意到4%的边际增加。本研究的另一个重要发现是,无论干燥机采用何种空气循环方式,对于大范围的吸收能量和环境空气温度数据,所获得的DPR值都是不变的。

Another important finding of present study relates to invariable DPR values obtained for a wide range of absorbed energy and ambient air temperature data irrespective of air circulation mode adopted for a dryer.","PeriodicalId":184093,"journal":{"name":"2011 World Congress on Sustainable Technologies (WCST)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126920779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In present experimental investigation, a modest attempt is made to study the influence of load density and size of food product on drying efficiency of solar dryer. In order to achieve this objective, the laboratory model of mixed-mode solar dryer is fabricated and tested under indoor simulated conditions. Experiments have been performed on dryer with cylindrical potato samples of different thicknesses (5, 8 10 and 18 mm) and loading density (1.08, 2.16, 3.24 and 4.33 kg/m2 of food sample tray area) under forced air circulation. The air mass flow through dryer system is kept constant at 0.011 kg/s (1.3 m/s). Experimental variation of food product moisture content with drying time data have been plotted and analyzed for a wide range of product size and loading density. Results of experimental investigation reveal that the load density and food product size have significant effect on drying efficiency. It is also found that load density has an increasing influence on efficiency whereas the opposite trend is observed for food product size. Sensitivity analysis results indicate that both the variables are equally sensitive to overall efficiency of the dryer.
在本实验研究中,我们尝试研究了负载密度和食品粒度对太阳能干燥机干燥效率的影响。为了实现这一目标,制作了混合模式太阳能干燥机的实验室模型,并在室内模拟条件下进行了测试。用不同厚度(5、8、10、18 mm)和装载密度(1.08、2.16、3.24、4.33 kg/m2食品样品托盘面积)的圆柱形马铃薯样品在强制空气循环条件下进行干燥试验。通过干燥系统的空气质量流量保持恒定在0.011 kg/s (1.3 m/s)。在较大的产品粒度和装载密度范围内,绘制并分析了食品含水率随干燥时间数据的实验变化。实验研究结果表明,负载密度和食品粒度对干燥效率有显著影响。负载密度对效率的影响越来越大,而对食品尺寸的影响则相反。灵敏度分析结果表明,这两个变量对干燥机的总效率同样敏感。
