  脑波FFT变换 调用格式见m文件头部说明(下边也复制了一份) 有配套.DLL.h.lib.ctf文件,可以在C或C++环境中调用 ------------------------------------ 保存为FFT.m文件 输入参数: N:进行FFT变换的点数(要求是2的N次幂); fs:信号的采样频率(frequency of simpling) sig:进行FFT变换的数组(一维)。 输出参数: f_sig:变换后的信号(一维数组) E_delta、E_theta 、E_alpha、E_beta分别表示δθαβ相应频段的能量加和。 other为其余频段的能量加和(供参考用) -------------------------------------------------------------------------- function[ f_sig ,E_delta , E_theta , E_alpha , E_beta , other ] = FFT( N , fs , sig )(EEG FFT transform is called m file format, see head illustrate the matching DLL files, you can be C or C++ to call------------------------ simpling) sig: to FFT transform array (one dimension). Output Parameters: f_sig: transformation of the signal (one-dimensional array) E_delta, E_theta, E_alpha, E_beta δθαβ, respectively, the energy increases and the corresponding frequency band. Other for the rest of the energy band increases, and (for reference) -------------------------------------------------------------------------- function [f_sig, E_delta, E_theta, E_alpha, E_beta , other] = FFT (N, fs, sig))

  • 少发故障的寿命分布拟合
    首先是针对无或单失效数据情形下,通过多层贝叶斯估计法得到失效概率过后,给出了寿命分布参数的加权最小二乘估计。然后如果失效数据不止一个,使用乘积限估计法来得到失效概率的估计值。(Firstly, the weighted least squares estimation of the life distribution parameters is given by the multi-layer Bayesian estimation method after the failure probability is obtained for the case of no or single failure data. Then if the failure data is more than one, the product limit estimation method is used to obtain the estimated value of the failure probability.)
