Business Process Execution Language for Web Services (abbreviated to BPEL) is a language for specifying business process behavior based on Web services. But it cannot ensure the correctness of desired specification and properties exhibited by the BPEL control flow. Based on an analysis of the grammar and control flow of BPEL language, we first propose a formal model for BPEL and give the semantics of the BPEL activities to generate the transition tuple. We then develop an algorithm to automatically transform part of the BPEL language into the input language of MCTK, a symbolic model checker developed by us, such that we can verify temporal and epistemic properties of the BPEL processes. Finally, we illustrate the effectiveness of the proposed algorithm through an example of Virtual Travel Agency Web Services Composition.
用于Web服务的业务流程执行语言(简称为BPEL)是一种用于指定基于Web服务的业务流程行为的语言。但是它不能确保BPEL控制流所显示的所需规范和属性的正确性。在对BPEL语言的语法和控制流进行分析的基础上,我们首先提出了BPEL的形式化模型,并给出了生成转换元组的BPEL活动的语义。然后,我们开发一种算法,将BPEL语言的一部分自动转换为MCTK的输入语言,MCTK是我们开发的一个符号模型检查器,这样我们就可以验证BPEL流程的时间和认知属性。最后,以虚拟旅行社Web服务组合为例,验证了该算法的有效性。

The Grid is emerging as a wide-scale distributed computing infrastructure that promises to support resource sharing and coordinated problem solving in dynamic multiinstitutional Virtual Organizations. To describe data, the Webservice issues have been extended with a relevance of Grids in education. To successfully summarize this in terms of a Webservice implementation strategy for a hypothetical enterprise, the implication of Grids and Web services for any organization is currently being developed at W3C. In this paper, the Core Grid Ontology for E-learning (CGOEL) is proposed, which provides the infrastructure on which to build the various Web service implementations. Finally, grid infrastructure is deployed to get easier as commercial support grows and the heroic efforts are packaged properly.

Pub Date : 2009-10-14 DOI: 10.1109/WGEC.2009.128
Haiou Guan, Shaohua Xu
This paper proposes the correction algorithm of lamina based on bilinear mapping aimed at the problems of image incline and geometric distortion when collecting field lamina images using digital camera. The validity of measurement has not been influenced by size, figure differentia and white background of laminae. The experiment shows that the accuracy can reach to 99% when using this method to correct the lamina image, which is the basement of extracting the lamina features.

Hierarchical reconstruction on image sequences is a hot issue recently. When occlusion exists, the result of reconstruction will be affected. This paper proposes an algorithm to solve the occlusion issue on image sequences. The conjugate gradient method is used to estimate the projective depth. Then the initial model is built to judge the outlier. Meanwhile the final result is built with effective value. The method is proved to be feasible according to the experiment result.

Laijun Wang, Da-wei Hu, Rui-zi Gong
Optimization model is build for solving the aircraft departure sequencing problem in this paper first. Then, an improved genetic algorithm (GA) using symbolic coding is proposed, where a type of total probability crossover and big probability mutation are performed. In this way, the evolutionary policy of Particle Swarm Optimization (PSO) is absorbed into the improved GA, which reduces the complexity and enhance the efficiency greatly. Last, a simulation program using basic GA, adaptive GA, and improved GA is performed. The simulation result shows that the model is effective and Improved GA has better performance than Basic GA or Adaptive GA.

Pub Date : 2009-10-14 DOI: 10.1109/WGEC.2009.193

Biological invasion is a major threat to biodiversity globally. It not only affects ecosystem structure and function, but also brings the economic and environmental impacts. To curb the societal, economic and environmental impacts of alien invasive species (AIS), we need realize the current status and hazard of biological invasions, and understand the invasive routes and mechanisms. Finally, we provide the theoretic connotation of biological invasions according to entropy increasing principle of Second Thermodynamics Law, and some advises on controlling biological invasions. Biological invasions, also called biological pollution, have two-dimension danger at horizontal and vertical scale, and two-channel way in natural and artificial way. The key of studying biological invasions is mechanism and principle. The mechanism of biological invasions focuses on the biological and ecological characteristic of alien invasive species, and frangibility of habitat. Its theoretic connotation embodies following aspects: entropy increasing of ecosystem will conduce to the degradation of energy; negative entropy is the source of life; biological invasion is the course of inputting positive entropy to ecosystem.
生物入侵是全球生物多样性面临的主要威胁。它不仅影响生态系统的结构和功能,而且带来经济和环境影响。为了遏制外来入侵物种对社会、经济和环境的影响,我们需要了解外来入侵物种的现状和危害,了解其入侵途径和机制。最后,根据热力学第二定律的熵增原理,给出了生物入侵的理论内涵,并对生物入侵的控制提出了建议。生物入侵,又称生物污染,在水平和垂直尺度上具有二维危害,在自然和人为方式上具有双通道危害。研究生物入侵的关键是机理和原理。生物入侵的机制主要研究外来入侵物种的生物学和生态学特征以及生境的脆弱性。其理论内涵体现在以下几个方面:生态系统熵的增加会导致能量的退化;负熵是生命之源;生物入侵是向生态系统输入正熵的过程。

0-1背包问题是计算机领域中典型的NP复杂问题。传统的求解背包问题的方法是递归回溯法和贪心法。采用递归回溯算法求解背包问题的思路的优点是它简单而且可以完全遍历搜索空间,一定能找到最优解但是解空间是指数增长的,当解空间大到一定程度时,用这种算法来解决背包问题是不现实的。贪心算法只能在最优解附近的一定范围内得到近似解

A Fast Motion Vector Estimation Method Based on Color Multidimension Projection 一种基于彩色多维投影的快速运动矢量估计方法
Pub Date : 2009-10-14 DOI: 10.1109/WGEC.2009.136
Xiao-Ning Wang, X. Han, Z. Yuan, Hongying Zhao
An approach of fast motion estimation (ME), aiming at the stabilization problem of video surveillance system on driving vehicle, is proposed in the paper. The information of color space based on multidimension projection and brightness based on grayscale projection (GP) are jointly considered. Compared with the traditional approaches of GP, the presented approach can be applied to achieve higher precision and remain real-time performance. Furthermore, it is more robust than GP, especially when brightness distribution of video image is nearly even. Meanwhile, scaling factor estimation is also applied, which is helpful to estimate motion vector(MV) from scaling motion mode.
