The nonsymmetry and antipacking pattern representation model （NAM）, inspired by the concept of the packing problem, uses a set of subpatterns to represent an original pattern. The NAM is a promising method for image representation because of its ability to focus on the interesting subsets of an image. In this paper, we develop a new method for gray-scale image representation based on NAM, called NAM-structured plane decomposition （NAMPD）, in which each subpattern is associated with a rectangular region in the image. The luminance function of pixels in this region is approximated by an oblique plane model. Then, we propose a new and fast edge detection algorithm based on NAMPD. The theoretical analyses and experimental results presented in this paper show that the edge detection algorithm using NAMPD performs faster than the classical ones because it permits the execution of operations on subpatterns instead of pixels.

Research on the Long-distance Transmission

第26届中国控制与决策会议

作者： Yang Li xueli wu Jianhua Zhang Quanmin Zhu Hebei University of Science and Technology University of the West of England Bristol BS161QYUK

In this paper, the problem of sliding mode control of a discrete-time switched system with uncertain parameters and time-varying delay is investigated. By using the average dwell time approach and the piecewise Lyapunov function technique, a sufficient condition is proposed to guarantee the exponential stability of the switched systems with uncertain parameters and time delays. The conservation of the obtained results is reduced by employing the delay partitioning method and the free-weighting matrix technique. A robust sliding mode controller has been designed to force the closed-loop system to be driven onto a prescribed sliding surface and maintained there for all subsequent time. Finally, a numerical example is given to illustrate the effectiveness of the proposed theory.

Energy and Power Engineering 2013年第4期5卷 1293-1297页

作者： xueli wu Xiuyuan Yang Hong Shen Qinyong Zhou China Electric Power Research Institute Beijing 100192 China Shool of Automation Beijing Information Science and Technology University Beijing 100192 China

In view of the imbalanced distribution of power load and resources, including the status of “electric shortage” in some cities in our country, the article discusses the long-distance transmission technology. It mainly analyzed two ways of the long-distance transmission: UHV AC transmission and UHV DC transmission. The fractional frequency transmission technology and half wavelength AC transmission technology of AC transmission are introduced. Some key technologies of long-distance transmission are described. It has a guess for long-distance transmission future direction.

汶川大地震十年后,在灾难、悲情、灾后重建的热忱之后,作为身处其中的作家阿来如何讲述地震带来的灾难、悲情、救赎?一场灾难究竟有多长?回家的路究竟有多长?《云中记》无疑是一次新的探索与尝试,它讲述在地的灾难,也尝试超越这一灾难;它讲述身体和精神的漂泊,也试图让身体和精神一起回家;它讲述个体和村庄的消亡,也祈颂生命再生的喜悦和安详。《云中记》是一个人的精神史,同时也是嘉绒藏区这一边地中国的乡村精神图谱;是一个名为“云中村”的村庄在自然灾难面前消亡的历史,也是一个普泛意义上的中国村庄在历史变迁中渐行渐远的历史。

藏族作家达真的长篇小说《康巴》构建了“康巴”这一独特的文学世界,融合了宏大历史、民间史、日常生活史等多重面向,重现了藏地历史的丰满厚重与含混驳杂,为近年来的藏地文学书写提供了新的视野。小说经由民族志、地方史的文学地理书写走向了对民族命运、国族命运的思考,在“地方性书写”与“总体性历史”之间搭建了一座桥梁。宏阔的时间与空间叙事显示了其史诗视野与史诗追求,但史诗性的追求和反史诗的叙述交织在一起,使叙事面临巨大的困境与难度。作家努力在民族国家叙述、地方叙述、庶民叙述等更为多元的意义上彰显融合、交流、大爱、悲悯的历史伦理,为“民族共同体”的建构提供了有效的历史注脚。
