说明: 虚拟仪器代表着目前测试仪器领域的发展方向,LabⅥEw语言是一种功能强大的仪器开发平台。对淹没在噪声中声发射信号的有效提取(去噪)是声发射信号处理技术的第一步,也是声发射信号处理的关键所在。本文介绍了基于小波变换的阈值去噪方法。在LabⅥEw平台上,通过仿真试验,对声发射信号的几种阈值法的去噪结果进行比较,选出一种适合声发射信号去噪的阈值准则。(Virtual instrument on behalf of the current developments in the field of testing equipment direction, Lab Ⅵ Ew language is a powerful development platform apparatus. Submerged in the noise of the acoustic emission signal in the effective extraction (denoising) is the acoustic emission signal processing technology, a first step, the acoustic emission signal processing is the key. In this paper, based on wavelet transform thresholding denoising method. Lab Ⅵ Ew in the platform through the simulation of acoustic emission signals of several denoising threshold method for comparison of results to elect a suitable acoustic emission signal de-noising threshold criteria.)

Web-Data-Mining.Bing-Liu
Web数据挖掘(世界著名计算机教材精选),作者BingLiu刘冰
刘兵(BingLiu),伊利诺伊大学芝加哥分校(UIC)教授,他在爱丁堡大学获得人工智能博士学位。刘兵教授是Web挖掘研究领域的国际知名专家,在Web内容挖掘、互联网观点挖掘、数据挖掘等领域有非常高的造诣,他先后在国际著名学术期刊与重要国际学术会议(如KDD、WWW、AAAI、SIGIR、ICML、TKDE等)上发布关于数据挖掘、Web挖掘和文本挖掘论文一百多篇。刘兵教授担任过多个国际期刊的编辑,也是多个国际学术会议(如WWW、KDD与AAAI等)的程序委员会委员。
本书旨在阐述web数据挖掘的概念及其核心算法,使读者获得相对完整的关于web数据挖掘的算法和技术知识。本书不仅介绍了搜索、页面爬取和资源探索以及链接分析等传统的Web挖掘主题,而且还介绍了结构化数据的抽取、信息整合、观点挖掘和Web使用挖掘等内容,这些内容在已有书籍中没有提及过,但它们在Web数据挖掘中却占有非常重要的地位。全书分为两大部分:第一部分包括第2章到第5章,介绍数据挖掘的基础;第二部分包括第6章到第12章,介绍Web相关的挖掘任务。
