原创相同域名下的不同端口的cookie可以共享

问题：在实际的项目中，经常有不同的项目部署在同一域名下，但是端口不同。但是两个项目之前需要共享cookie结果：这种情况时可以共享的,当清除其中一个cookie,另一个也会连带清除。但是两者有条件：1.使用前需要清除缓存；注：localStorage不可以共享...

EMD 模态选择问题

Information extraction from time series has traditionally been done with Fourier analysis, which use stationary sines and cosines as basis functions. However, data that come from most natural phenomena are mostly nonstationary. A totally adaptive alternative method has been developed called the Hilbert–Huang transform (HHT), which involves generating basis functions called the intrinsic mode functions (IMFs) via the empirical mode decomposition (EMD). The EMD is a numerical procedure that is prone to numerical errors that may persist in the decomposition as extra IMFs. In this study, results of numerical experiments are presented, which would establish a stringent threshold by which relevant IMFs are distinguished from IMFs that may have been generated by numerical errors. The threshold is dependent on the correlation coefficient between the IMFs and the original signal. Finally, the threshold is applied to IMFs of earthquake signals from five accelerometers located in a building
