Constructing three-dimension space graph for outlier detection algorithms in data mining

Outlier detection has very important applied value in data mining literature. Different outlier detection algorithms based on distinct theories have different definitions and mining processes. The three-dimensional space graph for constructing applied algorithms and an improved GridOf algorithm were proposed in terms of analyzing the existing outlier detection algorithms from criterion and theory.     

Which is better for presenting your data： table or graph？

This study aimed at investigating the characteristics of table and graph that people perceive and the data types which people consider the two displays are most appropriate for. Participants in this survey were 195 teachers and undergraduates from four universities in Beijing. The results showed people‘s different attitudes towards the two forms of display.     

Graph rigidity and localization of multi-robot formations

This paper provides theoretical foundation tor the problem ot localization in multi-robot formations. Sufficient and necessary conditions for completely localizing a formation of mobile robots/vehicles in SE(2) based on distributed sensor networks and graph rigidity are proposed. A method for estimating the quality of localizations via a linearized weighted least-squares algorithm is presented, which considers incomplete and noisy sensory information. The approach in this paper had been implemented in a multi-robot system of five car-like robots equipped with omni-directional cameras and IEEE 802.11b wireless network.     

图表追踪的一种机器实现方法

交换图表追踪法是同调代数中一种重要的证明方法.本文提出了一种基于前推的交换图表追踪的机器实现方法,它可以证明同调代数中一系列基于交换图的定理.该方法从定理的结论出发,通过构造辅助元素以及对辅助元素进行推导,能在有限步内给出定理的证明.本文提出的前推方法已经在Java开发平台上实现,同调代数中的五引理、九引理、蛇引理等的证明都可以由我们的程序自动产生.     

关于Sb-S-H_2O系和Sb-Na-S-H_2O系碱性负电位区的热力学研究

本文根据同时平衡原理和电中性原理对Sb-S-H_2O系及Sb-Na-S-H_2O系的碱性负电位区进行了常温下的热力学分析,提出了一个计算和绘制这种体系的电位-pH图的新方法。这个方法所包括的基本观点和计算步骤,原则上适用于一切有多种络合物形成的复杂体系;而且,含有多核络合物和复杂配位(氧代配位体)络合物以及配位体变价和变体的极复杂体系的电位-pH值计算,目前还只能用这种方法完成。     

地理图表判读技巧

地理图表的解读是近年来考试中重点考核内容。在近年来考试中经常出现的地理图表主要有：①经纬网图;②等值线图;③地理要素图;④统计图表;⑤景观图。这类型的试题设计。给判读、分析、比较提供了广阔的思维空间,同时也为考查空间概念、空间想象以及分析计算等技能提供了平台。     

数据库工具软件的开发

本文介绍数据库工具(DBFTOOLS)软件的设计思想和实现方法。在DBMS下建立的数据库，可在DOS下通过DBFTOOLS进行查询、统计、作图等操作。同时，由DBFTOOLS提供的一些功能函数，也可由用户程序独立调用。
