简介：一个新方法基于光线扫描的传统的方法被介绍了解决由采用线段在染色性图判定颜色的问题近似曲线--用多角形的近似闭曲线。然后，一个向量坐标能被用来描述曲线而不是曲线方程。判定在一个区域和一个点或一个地点之间的拓扑学关系因此是容易的。并且任何数据处理方法过时的人或物过去常节省存储器，它做改进光线扫描方法在颜色的测量是相当有用的。

简介：地理信息的网络服务开发了在网上分享的很快基于的数据。它有一个基本能力从搬运分享数据的效率的各种各样的用户，而是网络满足要求被网络资源的不同环境极大地影响。在以太网(FCoE)技术上的纤维隧道的出现最好解决这个问题。FCoE允许IP协议和纤维隧道网络交通在存在FCoE知道的驱动程序，网络信息中心，和开关上被带。它也向由保存所有纤维隧道的巩固构造的输入／输出(I/O)允许一条进化途径。FCoE由使用以太网并且允许工业避免创造另外一个简化顾客环境，为I/O的分开的协议巩固。FCoE增加的优点联网地理信息的运输效率。

简介：关联向量机器(RVM)的普通信号分类的一条新途径基于向量机器(SVM)和RVM被比较并且分析的支持的核方法被介绍，二发信号分类器。信号的开始的几个柔韧的特征作为分类器的输入被提取，然后，内核思维被用来隐含地印射特征向量到高维的特征空格，和多班RVM和SVM分类器被设计完成AM，CW，SSB，MFSK和MPSK信号识别。模拟结果看了那什么时候选了有的合适的参数，RVM和SVM为可比较的精确性，但是RVM有更少的学习时间和基础功能。RVM的分类速度比SVM快得多。
