现在有好多初学jsp的网友经常会问数据库怎么连接啊,怎么老出错啊?所以我集中的在这写篇文章供大家参考,其实这种把数据库逻辑全部放在jsp里未必是好的做法,但是有利于初学者学习,所以我就这样做了,当大家学到一定程度的时候,可以考虑用MVC的模式开发。-now with a lot of beginners jsp netizens often ask how database connectivity ah, ah how old mistakes? So I concentrated on writing this article for reference, but in fact this database logic placed jsp Lane is not necessarily a good practice, but is conducive to beginners learning, so I do this, when we learn a certain extent, we can consider the use of the MVC pattern of development.

Linux in a Nutshell, 5th Edition

Over the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don t consider themselves computer gurus. -Linux in a Nutshell, 5th Edition By Stephen Figgins, Robert Love, Arnold Robbins, Ellen Siever, Aaron Weber ... ... ... ... ... ... ... .....

小波变换在信号处理、图像处理、模式识别中的研究…
小波变换在信号处理、图像处理、模式识别、计算机视觉等
方面广泛应用。本文提出了一种基于Haar小波的时问序列相似
模式匹配模型.它首先对时间序列数据进行Haar小波变换.以
降低数据的维度。首先将所要查询的时间序列进行降维,也就是
对时间序列数据进行小波变换,对序列进行标准化131,得到降维
之后的小波序列.这样可以得到系数子集的良好近似采用尺度
序列表示原始序列.并将其看成多维空间中的一个点,通过计算
两序列差的平方和的平方根作为这两个时间序列的距离函效
(即欧氏距离)。用小波变换保持了局部性质。而欧氏距离就是要
判断相似性的距离函数.所以当在作完变换之后。通过低频分量
来压缩数据,成功的计算出实际距离的下界。如果计算的结果小
于一个由用户所定义的门槛值.则认为这两个时问序列是相似
的。

To reduce the data dimension. Will first want to check the time series dimension reduction, that is,
