代码说明:

提供了轴承诊断的一种方法:EMD+HILBERT 轴承是机械设备中最常用也最易损坏的零件。轴承故障信号属于非平稳信号,振动和噪声信号是轴承故障特征信息的载体。在Matlab平台上使用EMD技术对信号进行分解,然后利用希尔伯特变换技术对信号进行包络分析来提取轴承故障特征频率。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    X2分布检验,只要是用来检验数据是否属于正态,对数正态,伽马分布(X2 distribution of test data as long as they are used to test whether they are Normal, Lognormal, Gamma distribution)

    说明:  这个模型可以在MATLAB中,为数据库的进入,提供时间倒数,以防止过多地试密码,从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current value of time allowed for a connection to a database to be successful. FIRSTARG, an optional argument, is a string that specifies the JDBC driver to be used establishing the database connection. SECONDARG, an optional argument, is an integer that specifies the length of time the driver will attempt to make a connection to a database. If FIRSTARG is not specified then the default JDBC/ODBC bridge is used to establish the connection to the database. If function is used without arguments then the current time out value is returned. )
