Evaporative cooler operating on solar energy is a viable option in places where there is scarcity of grid power and is also useful for short term storage of farm products. This paper analyzes the performance of a commercial cooler operated on the solar power and its cost benefit analysis. The cooler is operated on grid power in first part and on solar power in second part. The saturation efficiency, cooling capacity and the energy consumption is calculated in both the cases. The efficiency ranged from 41 to 70 %, cooling capacity from 4625 to 12079 kJ/h and energy consumption from 0.113 to 0.184 kW. The cost benefit analysis gives a payback period of about 11.5 seasons for the cooler if used for only comfort. If the cooler is used continuously for short term storage of farm products, then the payback period is estimated to be of 21.5 months. The optimization of solar panel, battery and inverter cost is suggested to have the early pay back of the investment cost. The cooler installation is recommended in place where there is shortage or frequent fluctuation of grid power.
在电网电力不足的地方,利用太阳能运行的蒸发冷却器是一个可行的选择,而且对农产品的短期储存也很有用。本文分析了一种以太阳能为动力的商用冷却器的性能及其成本效益分析。第一部分采用电网供电,第二部分采用太阳能供电。计算了两种情况下的饱和效率、制冷量和能耗。效率范围为41% ~ 70%,制冷量范围为4625 ~ 12079 kJ/h,能耗范围为0.113 ~ 0.184 kW。成本效益分析显示,如果仅用于舒适性,冷却器的投资回收期约为11.5个季节。如果冷却器连续用于农产品的短期储存,则投资回收期估计为21.5个月。建议对太阳能电池板、蓄电池和逆变器的成本进行优化,使投资成本尽早收回。建议在电网电量不足或波动频繁的地方安装冷却器。

Conventional energy sources like coal and oil used for power generation causes various environmental problems like creating pollution and creating ecological imbalance. These sources are also depleting due to lesser use of alternative resources. Chimney operated solar power plant is one of the best alternative which can be used to produce power in large capacity with the use of solar energy. It consist of very few number of parts like turbine, collector and chimney. This paper consist of study of effect of different process parameters on the performance this chimney operated solar power plant. A small prototype model of this power plant is fabricated which has collector of 1.8 m diameter and chimney of maximum height of 2.0 m. D.C motor with small generator and blades is used as turbine to get power output. The various process parameters like temperature, pressure, velocity are used to determine power output and efficiency of power plant. Numerous mathematical correlations were used to correlate these input and output parameters. The effect of chimney height on these parameters was studied. It was determined that temperature and velocity are the important parameters which improves the performance of solar chimney power plant along with chimney height and collector diameter.
传统能源如煤和石油用于发电,会造成污染和生态失衡等各种环境问题。由于替代资源的使用减少,这些资源也正在枯竭。烟囱式太阳能发电厂是利用太阳能进行大容量发电的最佳替代方案之一。它由涡轮机、集热器和烟囱等少数部件组成。本文研究了不同工艺参数对烟囱式太阳能电站性能的影响。制作了该电厂的小型原型模型,集热器直径1.8 m,烟囱最大高度2.0 m。采用带小型发电机和叶片的直流电机作为涡轮输出功率。温度、压力、速度等各种工艺参数决定电厂的输出功率和效率。许多数学相关性被用来将这些输入和输出参数联系起来。研究了烟囱高度对这些参数的影响。确定了温度和速度与烟囱高度和集热器直径一起是提高太阳能烟囱电厂性能的重要参数。

Friction welding is a solid state welding processes in which the weld is obtained by the heat generated due to forging and friction. Now a day’s eco-friendly joining of dissimilar materials is the need of the industries. The advantages of friction welding process are reduction in production time and cost saving. Friction welding is classified into two types. One type is Inertia drive friction welding and the other is Continuous drive friction welding. In continuous drive friction welding one of the work pieces is held stationary while the other is held for a certain rotating speed. The two work pieces are brought together under certain friction pressure for a certain period of time known as friction time. Then, the rotation is stopped and upset pressure is applied for a certain upset time. Then, the spindle is disengaged and the component is unloaded. In Inertia drive friction welding one part is held stationary while the other is clamped in the chuck which is attached to the flywheel. The flywheel and chuck is rotated for a certain seed to store a predetermined energy. In this paper, review of friction welding on different materials and their weld ability has been discussed in brief.
摩擦焊是一种利用锻造和摩擦产生的热量获得焊缝的固态焊接工艺。如今,异种材料的环保连接是各行各业的需要。摩擦焊工艺的优点是缩短了生产时间,节约了成本。摩擦焊分为两种。一种是惯性驱动摩擦焊,另一种是连续驱动摩擦焊。在连续驱动摩擦焊接中,一个工件保持静止,另一个工件保持一定的旋转速度。在一定的摩擦压力下,两个工件在一定的时间内接触在一起,称为摩擦时间。然后,停止旋转并施加加厚压力以达到一定的加厚时间。然后,主轴脱离,组件卸载。在惯性驱动摩擦焊接中,一部分保持静止,而另一部分夹在附在飞轮上的卡盘中。飞轮和卡盘为一定的种子旋转,以储存预定的能量。本文简要介绍了摩擦焊在不同材料上的研究进展及其焊接性能。

In the software testing a real way of measuring effective testing is that the system passes an adequate suite of test cases, and then it must be correct or dependable. But that’s impossible because the adequacy of test suites is provably undecidable. So we’ll have to settle adequacy Design rules to highlight inadequacy of test suites. Design rules do not guarantee good designs. Good design depends on talented, creative, disciplined designers and that can be the best test suite set to fulfill adequacy criteria .
在软件测试中,衡量有效测试的真正方法是系统通过一组足够的测试用例,然后它必须是正确的或可靠的。但这是不可能的,因为测试套件的充分性是无法确定的。因此,我们必须解决充分性设计规则,以突出测试套件的不足。设计规则并不能保证好的设计。优秀的设计取决于有才华、有创意、有纪律的设计师,这是满足充分性标准的最佳测试套件。

Pub Date : 2017-05-27 DOI: 10.21013/JTE.V7.N2.P5
Bindu Varshini Kosanam, Abhinay Kukkadapu
Traffic congestion is one of the major problems in many of metro cities all over the world today. It affects daily life in many aspects such as improper time management, stress, frustration which leads to reckless driving. Average time to reach destination is decided by travel speed which is directly proportional to traffic congestion and also the wait time at each and every traffic signal. In this paper a novel Swarm Intelligence based Traffic Control System (SITS) inspired from nature mimicking (Particle Swarm Optimization) is discussed. This State of the art SITS with Six Degrees of Separation approach to traffic congestion is applying swarm intelligence to traffic lights to avoid waiting of vehicles at red light decreasing wait time and congestion. Here cars will not take random paths or will not take dynamic routes. Six degrees of separation will be employed at each node (traffic signal) to limit computational power and to improve efficiency.
交通拥堵是当今世界许多地铁城市面临的主要问题之一。它影响日常生活的许多方面,如时间管理不当,压力,沮丧,导致鲁莽驾驶。到达目的地的平均时间由旅行速度决定,而旅行速度与交通拥堵和每个交通信号的等待时间成正比。本文讨论了一种受自然模拟(粒子群优化)启发的基于群体智能的新型交通控制系统。这种最先进的六度分离交通拥堵方法是将群体智能应用于交通信号灯,以避免车辆在红灯前等待,减少等待时间和拥堵。在这里,汽车不会走随机路径,也不会走动态路线。每个节点(交通信号)将采用六度分隔,以限制计算能力并提高效率。

Gesture Control of Robotic Arm 机械臂的手势控制
Pub Date : 2017-05-10 DOI: 10.21013/JTE.V7.N1.P1

Robots have become a key technology in various fields. Robotic arms are mostly remote controlled by buttons or panels and sometimes in batch process they are autonomous. The usage of panel boards or control sticks includes a lot of hardwiring and subject to malfunction.  It also induces some stress on the operators. Hence major chemical industries like cosmetic manufacturing, paint manufacturing and Biosynthesis laboratory etc., which deals with hazardous environment due to the chemicals and other bio substances, involve humans for the processing. The aim is to reduce the bulk of wiring in the robotic arms and reduce the effort and number of operators in controlling the robotic arm operations. To implement gestures into the process this would be a major breakthrough. This can also be used as pick & place robot, a cleaning robot in chemical industries where a human does not need to directly involved in the process of cleaning the chemicals and also for coating underground tanks.
机器人已经成为各个领域的关键技术。机械臂大多由按钮或面板远程控制,有时在批处理过程中它们是自主的。面板或控制杆的使用包括大量的硬接线和容易发生故障。它还会给操作者带来一些压力。因此,主要的化学工业,如化妆品制造、油漆制造和生物合成实验室等,由于化学品和其他生物物质而涉及危险环境,需要人类进行处理。其目的是减少机械臂中布线的体积,减少操作人员控制机械臂操作的工作量和数量。在这个过程中实现手势将是一个重大突破。它也可以用作拾取机器人,化学工业中的清洁机器人,在化学工业中,人类不需要直接参与清洁化学品的过程,也可以用于地下储罐的涂层。

Robotic arms are mostly remote controlled by buttons or panels and sometimes in batch process they are autonomous. The usage of panel boards or control sticks includes a lot of hardwiring and subject to malfunction.  It also induces some stress on the operators. Hence major chemical industries like cosmetic manufacturing, paint manufacturing and Biosynthesis laboratory etc., which deals with hazardous environment due to the chemicals and other bio substances, involve humans for the processing. The aim is to reduce the bulk of wiring in the robotic arms and reduce the effort and number of operators in controlling the robotic arm operations.

Modern programming languages, especially object oriented languages facilitate to create libraries of reusable components (e.g. class definition). The majority of software companies are designing the components and reusing those wherever applicable. Maintaining such components (i.e. class library) and accessing those at right time in right form is challenging because large no. of components in library. Object Oriented Programming supports the reusability of the code. The major challenge in programming is to improve the learning quality and productivity of the software developer, subject teachers and students. To support programming in Java, researcher implemented a design retrieval algorithm which will make it possible to search through potentially reusable Java classes. The proposed work, selects the appropriate descriptors of the inputted cases - .java files. It will separate the code components automatically and stores in the repository. The different levels of ambiguity in selection of cases are controlled through data preprocessing technique of data mining. The set of adjustments applied to get the similarity of the code components.
现代编程语言,尤其是面向对象语言,有助于创建可重用组件的库(例如类定义)。大多数软件公司都在设计组件并在适用的地方重用它们。维护这些组件(即类库)并在正确的时间以正确的形式访问这些组件是具有挑战性的,因为大量的数据。库中的组件。面向对象编程支持代码的可重用性。编程的主要挑战是提高软件开发人员、学科教师和学生的学习质量和生产力。为了支持Java编程,研究者实现了一个设计检索算法,该算法可以搜索潜在的可重用Java类。建议的工作选择输入案例的适当描述符- .java文件。它将自动分离代码组件并存储在存储库中。通过数据挖掘的数据预处理技术控制案例选择的不同模糊程度。为获得代码组件的相似性而应用的调整集。
