CdTe grid-connected photovoltaic system at energy commission Malaysia: Performance and sustainability issues 马来西亚能源委员会的CdTe并网光伏系统:性能和可持续性问题
A. Junid, M. Hamdan, Shazrizal Bakar
Commissioned in November 2009, Malaysia's Energy Commission headquarters utilizes a 71.4kWp rated grid-connected Cadmium-Telluride (CdTe) thin-film photovoltaic system which meets approximately 10% of the building's average electrical power demand. As of June 2011, the photovoltaic panel performance degradation rate is about 3.4% over 1.67 years, i.e. 2% per annum. The system's economic sustainability may be represented by an estimated payback period of 21 years at an Internal Rate of Return (IRR) of 2–4%. Once a higher feed-in tariff supported by the Renewable Energy Act 2010 takes effect, IRR will increase and payback time will fall. Environmental sustainability is supported by the panel manufacturer's written policy that it will collect and recycle panels free of charge.
马来西亚能源委员会总部于2009年11月投入使用,采用71.4kWp额定并网碲化镉(CdTe)薄膜光伏系统,可满足建筑物平均电力需求的约10%。截至2011年6月,光伏板的性能退化率在1.67年内约为3.4%,即每年2%。该系统的经济可持续性可以用预计21年的投资回收期来表示,内部收益率(IRR)为2-4%。一旦《2010年可再生能源法案》支持的更高的上网电价生效,内部收益率将增加,投资回收期将缩短。电池板制造商的书面政策支持环境可持续性,该政策将免费收集和回收电池板。

Highly optimized OpenCV based cell phone 高度优化的基于OpenCV的手机
S. Sankaraiah, R. Deepthi
The new advancement in technology made cell phone as a smart phone with highly computing capabilities and low processing power. Currently, achieving real-time image processing routines such as convolution, edge detection, thresholding and some of complex media applications is a challenging task with the smart phone, because of limited memory and power constraints. An open software framework, Symbian OS is used in cell devices to provide a good starting point for developing the multitasking kernel, integrated with communication protocols, data management and graphical user interface for reducing the total development time. To resolve the problems faced by image processing applications in cell phones, new application environment is developed. This environment provides the resources available in the operating system which runs on the hardware with complex image processing libraries. These papers presents the capturing of an image from the printed media, applies to image processing algorithms to scaling and translation of the image, wipe out the noise, background subtraction, image rotation and detect edges. The developed software chops the comics strip along border into individual units, store on the permanent memory and and display on the handset. Implementation of image processing algorithm using Open Source Computer Vision Library (OpenCv), with Visual C++ Integrated Development Environment (IDE) and application Graphical User Interface is designed using Qt. Images are pre-processed with several image processing techniques, such as, RGB to Grey scale conversion, smoothening using Gaussian Filter, Histogram equalization, Detect Border (cumulative sum) and Set Region of Interest (ROI) crop. This developed software integrated in cells by the cross compilation of Qt and the OpenCV software for an Operating system. The result utilized the CANNY method in finding edges of the image using OpenCV. The integrated approach succeeded in cell phone by detecting the edges, chopping the images to required format of individual units, then stored it using OpenCV and finally displayed on a cell phone without any loss of image information. The impacts of memory latency, synchronization and the data management overhead are also studied and presented in this paper.
新的技术进步使手机成为一种具有高计算能力和低处理能力的智能手机。目前,由于有限的内存和功率限制,在智能手机上实现卷积、边缘检测、阈值处理和一些复杂的媒体应用等实时图像处理程序是一项具有挑战性的任务。Symbian OS是一个开放的软件框架,用于蜂窝设备,为开发多任务内核提供了一个良好的起点,集成了通信协议,数据管理和图形用户界面,以减少总开发时间。为了解决手机图像处理应用所面临的问题,开发了新的应用环境。这个环境提供了操作系统中可用的资源,这些资源运行在具有复杂图像处理库的硬件上。这些论文介绍了从印刷媒体上捕获图像,并将图像处理算法应用于图像的缩放和平移,消除噪声,背景减去,图像旋转和边缘检测。开发的软件将漫画条沿边界分割成单个单元,存储在永久存储器中,并在手机上显示。利用开源计算机视觉库(OpenCv)实现图像处理算法,利用Visual c++集成开发环境(IDE)和应用Qt设计图形用户界面,采用RGB到灰度转换、高斯滤波平滑、直方图均衡化、检测边界(累积求和)和设置感兴趣区域(ROI)裁剪等图像处理技术对图像进行预处理。本课题通过对Qt和OpenCV软件的交叉编译,开发了一个集成在单元中的操作系统软件。结果利用CANNY方法在OpenCV中寻找图像的边缘。该集成方法通过检测图像的边缘,将图像切割成所需的单个单元格式,然后使用OpenCV存储,最后在不丢失图像信息的情况下显示在手机上。本文还研究了存储延迟、同步和数据管理开销的影响。

Automatic generation of real time strategy tournament units using differential evolution 使用差分进化自动生成实时策略竞赛单元
Chang Kee Tong, C. K. On, J. Teo, Chua Bih Lii
This paper demonstrates the research results obtained for the application of Differential Evolution (DE) algorithm in a well known real time strategy game, namely Warcraft 3. The DE algorithm is one of the global optimizers that commonly used in solving real-time problems. In this work, the DE algorithm is combined with the conventional feed-forward artificial neural network in optimizing the solutions. The DE acts as an optimization technique used during evolution whilst the neural network operates as the controller in deciding the unit that should be spawned for mimicking the computer AI. The experimentation results show a group of mixed randomized opponent from a larger food limit can be defeated by the generated AI army using DE. Thus, it proofs that the DE used has successfully tuned the neural weights which acts as controllers in this tournament game. Furthermore, the generated controllers could decide the best units that should be spawned in defeating the opponent.

Performance comparison of PI and Fuzzy Logic Controller of a heat recovery steam generator (HRSG) 热回收蒸汽发生器(HRSG) PI与模糊控制器性能比较
Abdullah Sobri bin Nik Mu'tasim, I. Elamvazuthi
Heat recovery steam generator or HRSG is one of the big equipment that is productively being used these days to recover the heat and to produce it into steam which can be used in many applications. However, it is known that HRSG is a complex system with highly nonlinear characteristics and using conventional controller to control the system has brought a lot of drawbacks. Hence, to overcome these drawbacks, Fuzzy Logic Controller is employed to control the HRSG complex system. This paper discusses the design of a Fuzzy Logic Controller with three different membership functions which are 5, 7, and 9 that were used as pressure controller to control the input to HRSG based on the steam demand. The performances of the fuzzy logic controller were then compared with the classical PI controller.
热回收蒸汽发生器(HRSG)是一种大型设备,目前被广泛用于回收热量并将其转化为蒸汽,可用于许多应用。然而,众所周知,HRSG是一个高度非线性的复杂系统,使用传统的控制器对系统进行控制带来了很多弊端。因此,为了克服这些缺点,采用模糊控制器对HRSG复杂系统进行控制。本文讨论了一种模糊逻辑控制器的设计,该控制器具有5、7、9三种不同的隶属函数作为压力控制器,根据蒸汽需求控制HRSG的输入。然后将模糊控制器的性能与经典PI控制器进行了比较。

Intelligent traffic management system 智能交通管理系统
Prithvinath Manikonda, Anil Kumar Yerrapragada, Sai Sasank Annasamudram
This paper presents an intelligent traffic management system using RFID technology. The system is capable of providing practically important traffic data which would aid in reducing the travel time for the users. Also, it can be used for other purposes like tracing of stolen cars, vehicles that evade traffic signals/tickets, toll collection or vehicle taxes etc. The system consists of a passive tag, an RFID reader, a microcontroller, a GPRS module, a high-speed server with a database system and a user module. Using RFID technology, this system collects the required data and calculates average speed of vehicles on each road of a city under consideration. It then transmits the acquired data i.e., average speed calculated at various junctions to the central computation server which calculates the time taken by a vehicle to travel in a particular road. Through Dijkstra's algorithm, the central server computes the fastest route to all the nodes (junctions) considering each node as the initial point in the city. Therefore, the system creates a map of shortest time paths of the whole city. This data is accessed by users through an interface module placed in their vehicles.
本文介绍了一种基于RFID技术的智能交通管理系统。该系统能够提供实际重要的交通数据,这将有助于减少用户的旅行时间。此外,它还可用于其他用途,例如追踪被盗车辆、逃避交通信号/罚单、通行费或车辆税的车辆等。该系统由无源标签、RFID读写器、微控制器、GPRS模块、带数据库系统的高速服务器和用户模块组成。该系统利用射频识别技术收集所需数据,并计算出考虑的城市每条道路上车辆的平均速度。然后,它将获得的数据,即在各个路口计算出的平均速度传输到中央计算服务器,该服务器计算车辆在特定道路上行驶所需的时间。通过Dijkstra算法,中央服务器将每个节点视为城市的初始点,计算到所有节点(结点)的最快路径。因此,系统创建了整个城市的最短时间路径地图。用户可以通过安装在车辆中的接口模块访问这些数据。
