华中电网调度员培训仿真系统(OTS) 的实用化应用

华中电网调度员培训仿真系统(OTS）是2000年底从国外某大公司引入的产品。在缺少培训和没有技术支持的情况下，经过华中网调人员自身艰苦努力，自2002年5月使该系统恢复正常运行。OTS系统从2002年8月正式投入电网实际生产运行以来，已多次成功地应用于华中电网的反事故演习。     

地形图点状虚线的自动矢量化研究与实现

虚线的矢量化一直是地形图自动识别的难点之一。文章通过人眼对虚线视觉感知特性的分析，提出了基于点与点之间相互作用的视觉组织模型。根据感知的类似性对地图图像进行形态滤波，然后运用有界深度优先搜索法生成初始种子段，提出可变形模型迭代算法实现对虚线的自动跟踪矢量化。从理论分析及实验结果得出，本算法是行之有效的，具有稳定性好、易于实现的特点。

Some functional inequalities and inclusion relationships associated with certain families of integral operators

By making use of certain familiar integral operators, the authors introduce and investigate several new subclasses of starlike, convex, close-to-convex, and quasi-convex functions. Among other results presented here, the authors establish a number of inclusion relationships associated with some of these integral operators. Some of the results established in this paper would provide extensions of those given in earlier works.     

机器视觉在大型工件自动探伤检测中的应用

大型金属工件探伤一般用无损检测法，技术难度高、工程量大，往往难以获得精度的测量准确值。针对机器视觉产品将被摄取目标转换图像信号后，多数都还依赖于手工进行处理问题，文章提出了一种基于边缘撮的工业CT（断层）图像几何尺寸的自动测量方法。该方法采用Canny算子提取图像边缘信息，并在图像边缘上实现对大型工件CT图像的内部结构尺寸和缺陷尺寸的自动测量。该方法已成功地应用于工业CT图象处理软件中，实际应用表明，它具有较高的精确度和重复性。

一种求解数值优化问题的非线性遗传算法

由于算术杂交算子的线性搜索范围及变异算子的随机搜索，导致了实数遗传算法的效率较低．为此，通过拓展遗传算子的搜索范围，提出了一种动态双层非线性杂交算子，并将混沌搜索引入变异算子，从而给出了一种求解数值优化问题的非线性遗传算法．实例仿真证明该算法的有效性，并以“平均截止代数”和“平均截止代数分布熵”作为评价指标，对该方法的优化效率进行了研究，定量的评价了该方法的优化效率，通过与实数遗传算法进行比较，进一步说明了该方法的优化效率高于实数遗传算法。     

数据流查询处理中一种共享的分级窗口维护策略

由于数据流具有无界的特性,数据流系统中的查询多为带有窗口的查询,对带有窗口的查询,现有方法常由操作符直接维护窗口,但操作符的类型及排列方式可能会导致窗口难以维护,且冗余度较大.因此提出一种查询处理中的分级窗口维护策略,将窗口分为流窗口和操作符窗口,以流窗口为主并控制操作符窗口的维护,使查询中的窗口保持一致,解决了窗口维护问题,并且符合流查询语言的语义,各级窗口中的数据通过共享来解决内存消耗问题.     

Enumerating maximal bicliques in bipartite graphs with favorable degree sequences

We propose an output-sensitive algorithm for the enumeration of all maximal bicliques in a bipartite graph, tailored to the case when the degree distribution in one partite set is very skewed. We accomplish a worst-case bound better than previously known general bounds if, e.g., the degree sequence follows a power law.     

Failure mode and effects analysis using intuitionistic fuzzy hybrid weighted Euclidean distance operator

Failure mode and effects analysis (FMEA) has shown its effectiveness in examining potential failures in products, process, designs or services and has been extensively used for safety and reliability analysis in a wide range of industries. However, its approach to prioritise failure modes through a crisp risk priority number (RPN) has been criticised as having several shortcomings. The aim of this paper is to develop an efficient and comprehensive risk assessment methodology using intuitionistic fuzzy hybrid weighted Euclidean distance (IFHWED) operator to overcome the limitations and improve the effectiveness of the traditional FMEA. The diversified and uncertain assessments given by FMEA team members are treated as linguistic terms expressed in intuitionistic fuzzy numbers (IFNs). Intuitionistic fuzzy weighted averaging (IFWA) operator is used to aggregate the FMEA team members’ individual assessments into a group assessment. IFHWED operator is applied thereafter to the prioritisation and selection of failure modes. Particularly, both subjective and objective weights of risk factors are considered during the risk evaluation process. A numerical example for risk assessment is given to illustrate the proposed method finally.
