Meiling Lu, Song Liu, Peng Liu, Qiaoshuo Li
User interaction is an important part of the smart grid construction. In order to allow power consumers to have a better understanding of their own household electricity, it is necessary to provide them with real-time electricity information. On the basis of intensive study of the electricity information acquisition system, this paper puts forward a construction scheme of power information visualization platform based on smart meter. The scheme only needs to upgrade and transform the carrier communication module of the smart meter instead of changing the existing electricity information acquisition system. As the modified module increases WiFi communication function, users can establish a communication link with their own smart meter through WiFi. The mobile phone can send a series of instructions which follow the DL/T 645-2007 protocol to call all kinds of power information and data in the smart meter. The platform shows the electricity information to users in a simple and intuitive way. Users can easily check a variety of household power information through the phone app. The platform solves the problem of difficult view of information in the electric meter. It expands application results of the smart meter, meanwhile promotes the friendly communication between the power grid and users.

Statistical-Based Bayesian Algorithm for Effective Email Classification 基于统计的有效邮件分类贝叶斯算法
Xianghui Zhao, Yangping Zhang, Junkai Yi
Email is an incontestable communication mode in both professional and personal correspondences. The survey shows that an ordinary white-collar worker spend at least an hour every day to deal with the email. Handling spam which is disguised as normal email is waste our time. In this paper, we propose a spam detection method upon statistical-based Bayesian algorithm. Firstly, the method use actual priori probability of spam instead of constant probability. Secondly, the selective range and rules of tokens is improved. Finally, our method add URLs and images into detection content. The experiment result shows that the improved statistical-based Bayesian classification algorithm works well in practice.

Singularity Analysis of a Novel 4-DOF Surgical Robot 新型四自由度手术机器人的奇异性分析
Alaa Khalifa, M. Fanni, Abdelfatah M. Mohamed
This paper presents the singularity analysis of a novel endoscopic surgical parallel manipulator. The 4-DOF, 2- PUU_2-PUS, surgical robot design has larger bending angles and workspace volume. All previous manipulators have a zero pitch and infinity pitch reciprocal screws, so it is easy to find out the singular configurations inside the workspace. On the other hand, the novel 4-DOF surgical robot (2-PUU_2-PUS) has h-pitch reciprocal screws. The known geometrical approach for reciprocal-screws could not provide all singular configurations of the novel manipulator. Geometrical/Analytical approach for reciprocal-screws based singularity analysis of 2-PUU_2-PUS is proposed. The proposed algorithm can find all singular configurations of any limited DOF parallel manipulator with h-pitch reciprocal screws. The results show the feasibility of the proposed algorithm to find all singular configurations of the 4-DOF parallel manipulator. The discovered singularity configurations shrieked greatly the singularity free workspace to one fourth the original workspace. In order to be able to work through the entire workspace, we suggest changing the topology structure of the manipulator.
本文介绍了一种新型内镜手术并联机械臂的奇异性分析。4自由度2- PUU_2-PUS手术机器人设计具有更大的弯曲角度和工作空间体积。以往的机械手都有一个零螺距和无穷螺距的倒易螺钉,因此很容易找到工作空间内的奇异构型。另一方面,新型4-DOF手术机器人(2-PUU_2-PUS)具有h-螺距倒数螺钉。已知的往复式螺杆几何方法不能提供该新型机械手的所有奇异构型。提出了基于往复螺杆的2-PUU_2-PUS奇异性分析的几何/解析方法。该算法可以求出任意具有h-螺距倒螺杆的有限自由度并联机构的所有奇异构型。仿真结果表明,该算法能够求解出四自由度并联机构的所有奇异构型。所发现的奇点构型将奇点自由工作空间提高到原工作空间的四分之一。为了能够在整个工作空间内工作,我们建议改变机械手的拓扑结构。

Research on Improvement of KD-RTI Communication Mechanism Base on DDS 基于DDS的KD-RTI通信机制改进研究
Yibin Tu, J. Hao, Xiang Ji, Xiaoyuan Zhou
KD-RTI which is developed by National University of Defense Technology, is the run-time infrastructure of HLA simulation, and it is widely used in distributed simulation field. With the expansion of the scale of distributed simulation system, the data flow in the simulation system is more and more complex. However, KD-RTI only provides "best-effort" and "reliable" services, which cannot guarantee the quality of service of communication. To solve this problem, we use DDS as a communication method of KD-RTI. DDS is a data-centric publish-subscribe specification and it has a network controllable mechanism with lots of Quality of Service (QoS) policies. Experiments show that the improved KD-RTI perform better than the original KD-RTI in dealing with complex data streams.
KD-RTI是由国防科技大学开发的HLA仿真运行时基础设施,在分布式仿真领域得到了广泛的应用。随着分布式仿真系统规模的不断扩大,仿真系统中的数据流也越来越复杂。然而,KD-RTI只提供“尽力而为”和“可靠”的服务,并不能保证通信的服务质量。为了解决这个问题,我们使用DDS作为KD-RTI的通信方式。DDS是一种以数据为中心的发布-订阅规范,具有网络可控机制和大量的服务质量(QoS)策略。实验表明,改进后的KD-RTI在处理复杂数据流方面优于原始KD-RTI。

A New Method of Spacecraft Assembly Integration Alignment Test Based on Virtual Cubic Prism 基于虚拟立方棱镜的航天器装配一体化对准试验新方法
Wang Wei, Guo Jieying, Tao Li, Liu Haomiao
With the development of Chinese space technology, the structure of a spacecraft is increasingly complex. The conventional method of spacecraft assembly integration alignment test based on real cubic prism cannot realize the measurement of the installation angles of the equipment in spacecraft coordinate system due to the limitation of the equipment's installation position. This paper proposes a new method of spacecraft assembly integration alignment test based on virtual cubic prism. The method constructs a virtual cubic prism using two unrelated vectors successfully and then uses the cubic prism as the transfer benchmark to calculate the installation angles of the measured equipment in spacecraft coordinate system. The method has been verified, accepted and applied to the alignment test of subsequent models.

A Positioning System Based on Monocular Vision for Industrial Robots 基于单目视觉的工业机器人定位系统
Mingyu Gao, Yeqing Yan, Yuxiang Yang, Jiye Huang, Zhiwei He
In order to make the industrial robot catch the target object accurately, an automatic positioning system based on monocular vision is proposed in this paper. Specifically, efficient localization algorithms are applied to get the position information of the target object. Besides, in consideration of further application requirements, an additional recognition algorithm based on 2-1 Hough transform is adopted to recognize the welding points on the accumulator. Moreover, a pose estimation algorithm is also used to obtain the posture information of the object. Then the information is converted to the robot's basal coordinate and transmitted to the robot motion controller by a serial port. Finally, a trajectory planning algorithm based on circular interpolation is applied for the 6-DOF industrial robot to capture the objects. The experimental results demonstrate that the proposed methods can recognize and acquire the pose of the target object accurately, so as to guide the industrial robot to catch the object reliably. The proposed positioning system can well meet the requirements of actual industrial productions.

A Template Independent Approach for Web News and Blog Content Extraction 一种独立于模板的网络新闻和博客内容提取方法
Xueyang Ma, Hongli Zhang, Xiangzhan Yu, Yingjun Li
The Web has become a large platform for information publishing and consuming. Web news and blog are both representative information sources providing convenient ways to keep informed. In addition to the main content, most web pages also contain navigation panels, advertisements, recommended articles etc. Effectively extracting news and blog content and filtering these noises is necessary and challenging. In this paper we propose a news and blog content extraction approach that is portable to different languages and various domains. Our extensive case studies shows that characters which are not anchor texts but contain stop words are more likely to be the genuine content. Our method first traverses the entire DOM tree and count these valid characters attached to each DOM node. Then we step into the most representative child node based on valid characters recursively. And we finally stop at the main content node with a predefined criterion. To validate the approach, we conduct experiments by using online news and blog files randomly selected from well-known Chinese and English websites. Experimental result shows that our method achieves 96% F1-measure on average and outperforms CETR.
网络已经成为信息发布和消费的大平台。网络新闻和博客都是具有代表性的信息来源,提供了方便的获取信息的方式。除了主要内容外,大多数网页还包含导航面板、广告、推荐文章等。有效地提取新闻和博客内容并过滤这些噪音是必要的,也是具有挑战性的。在本文中,我们提出了一种可移植到不同语言和不同领域的新闻和博客内容提取方法。我们广泛的案例研究表明,那些不是锚文本但包含停顿词的字符更有可能是真正的内容。我们的方法首先遍历整个DOM树,并对附加到每个DOM节点的有效字符进行计数。然后根据有效字符递归进入最具代表性的子节点。最后,我们在带有预定义标准的主内容节点处停下来。为了验证这一方法,我们从知名的中英文网站中随机选取了在线新闻和博客文件进行实验。实验结果表明,该方法平均达到96%的f1度量,优于ctr。

Medical Image Segmentation Based on the Watersheds and Regions Merging 基于流域与区域融合的医学图像分割
Huang Zhanpeng, Zhang Qi, Jiang Shizhong, C. Guohua
The accurate medical image segmentation is the basis of 3D visualization and diagnosis. A medical CT image segmentation algorithm is proposed based on watershed segmentation and regions merging to extract the liver area. The similarity criteria for the regions merging is calculated by automatically analyzing the grayscale distribution of nearby areas of the seed points selected by the user. Then, the Gaussian filter is used to smooth the CT image. And the gradient of the smoothed image is calculated by the multi-scale morphological gradient, which is the input image for Watershed segmentation. The result of the Watershed segmentation is a labeled image, and the labeled regions are merged based on the similarity criteria. Finally the region of liver is extracted by selecting the max region, and the holes in the liver area are filled, which are the vessel areas of the liver. Experimental results show that the algorithm can accurately extract the liver region in the image with little user involvement.
医学图像的准确分割是三维可视化和诊断的基础。提出了一种基于分水岭分割和区域合并的医学CT图像分割算法,提取肝脏区域。通过自动分析用户选择的种子点附近区域的灰度分布,计算区域合并的相似度准则。然后,利用高斯滤波对CT图像进行平滑处理。通过多尺度形态梯度计算平滑后的图像的梯度,作为分水岭分割的输入图像。分水岭分割的结果是一个标记的图像,并根据相似度标准合并标记的区域。最后通过选取最大区域提取肝脏区域,填充肝脏区域的孔洞,这些孔洞就是肝脏的血管区域。实验结果表明,该算法可以准确地提取图像中的肝脏区域,且用户参与较少。

Objective: Using the target classification is too complex be used to distinguish between natural objects and Man-made objects in aerial image, so in this paper, we analyze the target classification and feature of the target in the sea instead. According to the features of the contour map, a method for eliminating natural objects is proposed. Methods: First, we decompose the contour map through perspective transformation, to establish the estimate of the true image, second, the Fourier-mellin transformation is adopted to match the outline of estimate object image with the outline of true object image (matching), and then we use Hausdorff distance to correct the preliminary matching, Finally, we adopt the difference method to remove the natural objects. Results: The experimental results show that the method can effectively remove the natural objects and keep the Man-made objects in the observed image. Conclusion: In this study, we propose a new method of removing the natural objects based on the known contour information of perspective transformation and It has been proved by the experimental results that this method is feasible for target detection by reducing the difficulty of target detection and improving the efficiency of target classification.
目的:利用目标分类方法区分航拍图像中的自然目标和人造目标过于复杂,因此本文转而分析海上目标的分类和特征。根据等高线地图的特点,提出了一种消除自然物体的方法。方法:首先通过透视变换对等高线图进行分解,建立对真实图像的估计,然后采用Fourier-mellin变换将估计目标图像的轮廓与真实目标图像的轮廓进行匹配(匹配),然后利用Hausdorff距离对初步匹配进行校正,最后采用差分法去除自然物体。结果:实验结果表明,该方法可以有效地去除观测图像中的自然物体,保留观测图像中的人造物体。结论:在本研究中,我们提出了一种基于已知透视变换的轮廓信息去除自然物体的新方法,通过实验结果证明,该方法降低了目标检测的难度,提高了目标分类的效率,对于目标检测是可行的。
