The influence of conduction band location on the leakage current level of a glass insulator 导带位置对玻璃绝缘子漏电流水平的影响
Moch. Dhofir, Danang Dwi Andaru, R. Hasanah
This paper discusses the influence of conduction band location on the leakage current level of a glass insulator. A sodium chloride solution has been used as a pollutant forming the conduction band. The solution concentration has been changed by using five variations of salt mass which was dissolved into 250 ml of water. The salt mass variation is proportional to its related mole equivalent of sodium chloride solution concentration. The experiment results indicate that the position of the conduction band on the insulator surface affects the surface resistivity. The largest resistivity occurs when the conduction band is located near the ground side, whereas the smallest one occurs when the band is in the middle between the ground side and the HV side. The value of the surface resistance for the band located on the HV side is between that near the ground side and that in the middle location. The level of the leakage current on the glass surface rises with the increase in the applied AC voltage. The leakage current increase is relatively linear up to around 20 kV, beyond which the leakage current starts to decrease. This decrease is related to the formation of dry bands which will increase the overall resistance of the glass insulator surface. The largest power and annual energy losses being caused by the leakage current are found when the conduction band is located in the middle part of the surface, whereas the smallest ones are obtained when the conduction band is located on the ground side. The power and annual energy losses increase even greater when the applied voltage is higher.
本文讨论了导带位置对玻璃绝缘子漏电流水平的影响。氯化钠溶液被用作形成传导带的污染物。将溶解于250毫升水中的五种不同的盐质量改变了溶液的浓度。盐的质量变化与其相关的氯化钠溶液浓度的摩尔当量成正比。实验结果表明,导电带在绝缘子表面的位置影响绝缘子表面电阻率。导带靠近地侧时电阻率最大,导带位于地侧与高压侧中间时电阻率最小。高压侧带的表面电阻值介于近地侧和中间位置的表面电阻值之间。玻璃表面的泄漏电流水平随着施加的交流电压的增加而上升。泄漏电流在20kv左右呈相对线性增长,超过20kv泄漏电流开始减小。这种减少与干燥带的形成有关,这将增加玻璃绝缘子表面的总电阻。泄漏电流造成的功率损失和年能量损失最大的是导电带位于表面中部,最小的是导电带位于地侧。当施加的电压较高时,功率和年能量损失增加得更大。

Mobile device combine the study of image track and surveillance monitor system 移动设备结合图像跟踪和监控监控系统的研究
Wang Zhi-hao, Kung Yu-Fan, Chen Yu-Yan, Hendrick, Aripriharta, Jong Gwo-Jia
In modern day societies, children sometimes are taking care by the housemaid, and the parent needs to monitor the house from their office. This paper presents the image tracking surveillance system which can be used to monitor and care for infants and young children. We used a grayscale image from 0 to 255. The proposed algorithm is Binary Thresholding where each pixel of the image is compared with the threshold value. We set the threshold to black in order to reduce the complexity of image information. Thus, the image can be established by background subtraction method. The tracking mechanism will start using temporal difference and object segmentation that carries out of dynamic Image Tracing. If the tracking object is beyond the warning range so the system will take the initiative to issue a warning. The future can be through the cloud server for a huge amount of image analysis, and establish to the multi-user remote monitoring function.
在现代社会,孩子们有时是由女佣照顾,父母需要从他们的办公室监视房子。本文介绍了一种可用于婴幼儿监护的图像跟踪监控系统。我们使用从0到255的灰度图像。所提出的算法是二值阈值,其中图像的每个像素与阈值进行比较。为了降低图像信息的复杂度,我们将阈值设置为黑色。因此,可以通过背景减法建立图像。跟踪机制将开始使用时间差分和目标分割进行动态图像跟踪。如果跟踪对象超出预警范围,系统将主动发出预警。未来可以通过云服务器对海量的图像进行分析,并建立到多用户的远程监控功能。

Transmission Control Protocol (TCP) is one of the protocols that work in the OSI (Open System Interconnection) modeling transport layer. TCP was designed more for wired networks. However, to meet the need for rapid development of network technology based on user needs, further development is needed for the use of TCP on wireless devices. One of the implementation of wireless-based network is mobile technology Long Term Evolution (LTE) broadband offering advantages, especially in terms of access. TCP Tahoe, TCP Reno, TCP SACK, and TCP Vegas are variants over the LTE network model with scenario. First is the view Throughput of each TCP variants when only one variant Certain working in the network. Both observe throughput All variants of TCP at the same time and have a QoS Equivalent, but with the possibility of a small congestion based on the capacity of the links made sufficient.
传输控制协议(TCP)是在OSI(开放系统互连)建模传输层中工作的协议之一。TCP更多的是为有线网络设计的。然而,为了满足基于用户需求的网络技术快速发展的需要,TCP在无线设备上的使用还需要进一步发展。基于无线网络的实现方式之一是移动技术长期演进(LTE)宽带提供的优势,特别是在接入方面。TCP Tahoe、TCP Reno、TCP SACK和TCP Vegas是LTE网络模型的变体。首先是当网络中只有一个特定的TCP变体工作时,每个TCP变体的视图吞吐量。两者都同时观察吞吐量TCP的所有变体,并具有等效的QoS,但基于链路容量的小拥塞的可能性足够。

Real time moving object extraction based on area filling 基于区域填充的实时运动目标提取
Panca Mudjirahardjo, H. Suyono, R. A. Setyawan
Moving object extraction is the first task for motion detection and recognition. It usually is performed from several frames to distinguish foreground from the background. In this paper we developed a simple extraction method which was suitable for real time application. First, we performed moving object detection by using frames subtraction. This yielded edge label in the motion area. This edge label couldn't extract the whole moving object. To extract the whole moving object, we performed filling operation followed by intersection and union operation to fill the area within the label. The experimental result, our system can extract the moving object in computation time of 116–296 ms, video rate of 15 frames per second (fps) and image frame size of 640×480 pixels, which is suitable for real time application.
运动目标提取是运动检测与识别的首要任务。它通常从几个帧中执行,以区分前景和背景。本文提出了一种适合于实时应用的简单提取方法。首先,我们使用帧减法进行运动目标检测。这产生了运动区域的边缘标签。这种边缘标签不能提取整个运动物体。为了提取整个运动物体,我们先进行填充操作,然后进行交集和并集操作来填充标签内的区域。实验结果表明,该系统可以在116-296 ms的计算时间内,以15帧/秒(fps)的视频速率和640×480像素的图像帧大小提取运动目标,适合于实时应用。

Low cost operation of an off-grid wind-PV system electrifying residential homes through combinatorial optimization by the RCGA RCGA通过组合优化实现离网风电光伏系统的低成本运行
N. Tutkun, Ozay Can, A. Afandi
A low power off-grid wind-photovoltaic system is increasingly used to energize residential homes in remote areas where no grid utility or grid extension is available. An economic design of such a system for 20-year lifetime requires optimal unit sizing as well as investment, operation and maintenance costs. However power generation by this system varies from one day to another due to irregular natures of wind speed and solar irradiation. Therefore battery storage is needed to integrate into this system if all the electrical appliances are desired to uninterruptedly feed and this requires to efficiently manage battery operation. Besides, load shifting can be applied to such a system through controllable loads in order to balance generation and consumption at each time interval as much as possible. One way to balance generation and consumption in a specified period is possible to solve a discrete optimization problem defined as minimization of daily cost with few constraints for optimal time slots.

低功率离网风力光伏系统越来越多地用于偏远地区的住宅,这些地区没有电网公用设施或电网扩展可用。这种系统的经济设计需要20年的使用寿命,需要最佳的单元尺寸以及投资、操作和维护成本。然而,由于风速和太阳辐射的不规则性质,该系统的发电量每天都在变化。因此,如果所有电器都希望不间断供电,则需要将电池存储集成到该系统中,这就需要有效地管理电池运行。此外,可以通过可控负荷对该系统进行负荷转移,使每个时间间隔的发电量和用电量尽可能达到平衡。在特定时间段内平衡发电和消耗的一种方法是解决离散优化问题,该问题被定义为在最优时间段很少约束的情况下使每日成本最小化。本研究从多个方面利用实编码遗传算法技术实现了系统总成本的最小化。所得结果对该低成本系统的设计和运行具有一定的指导意义。

An economic design of such a system for 20-year lifetime requires optimal unit sizing as well as investment, operation and maintenance costs. However power generation by this system varies from one day to another due to irregular natures of wind speed and solar irradiation. Therefore battery storage is needed to integrate into this system if all the electrical appliances are desired to uninterruptedly feed and this requires to efficiently manage battery operation. Besides, load shifting can be applied to such a system through controllable loads in order to balance generation and consumption at each time interval as much as possible. One way to balance generation and consumption in a specified period is possible to solve a discrete optimization problem defined as minimization of daily cost with few constraints for optimal time slots.

An intelligent system for land suitability assessment of tobacco 烟草土地适宜性评价智能系统
Nanik Tri Ratnawati, Subiyanto, U. M. Arief
High level of tobacco exports value required step-up of tobacco productivity. Productivity needs is not comparable with land availability, so that required land optimization with assessing land suitability. In the current trend of suitability assessment techniques is use intelligent system. This paper presents a research on improvement accuracy of land suitability assessment for tobacco using intelligent system. Each sub-criteria assessment has result of standardization and weight values. Suitability index and land suitability classes were obtained from calculation of the standardization results and the weights of each sub-criteria before being overlaid with spatial data to produce land suitability maps for tobacco. This map has been shows every land suitability class for tobacco cultivation. The result of system assessment was validated using yields of tobacco and compared with conventional method. The result assessment show intelligent assessment more accurate than conventional assessment system.
烟草出口值的高水平要求提高烟草生产力。生产力需求与土地可得性不可比较,因此需要通过评估土地适宜性进行土地优化。在目前适宜性评价技术的发展趋势中,采用智能系统。本文研究了利用智能系统提高烟草土地适宜性评价精度的方法。每个子标准评估都有标准化结果和权重值。根据标准化结果和各子标准的权重计算得到适宜性指数和土地适宜性等级,并与空间数据叠加生成烟草土地适宜性图。这张地图显示了每一块适合种植烟草的土地。用烟叶产量对系统评价结果进行了验证,并与常规方法进行了比较。结果表明,智能评估比传统评估系统更准确。
