Based on the new cumulant matrix, a simple iterative BSS algorithm is proposed, which requires neither centering nor sphering of the data and separates the mixed signals directly.

本文定義了一種新的累積量矩陣国产精品视频区一区二，對這種累積量矩陣的計算實際上只需要對二階累積量進行估計3344e国产在线观看，因而相對于常規(guī)的累積量矩陣的估計日韩精品一区二区在线观看网址，該方法計算簡單www.91在线，并且有可能達到較小的估計偏差日韩电影久久久久久精品视频。

The cartridge may have sphering mechanism which has a channel or loop with a configuration for reducing or eliminating cell settling.

這種試樣盒可具有球化機構(gòu)网友自拍日韩视频网站，這種球化機構(gòu)具有通道或環(huán)路，這種通道或環(huán)路帶有用于減少或消除細胞沉淀的構(gòu)造。

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.
