How to securely send data from local client to remote server using paramiko (codes included)
Paramiko module can be used in Python to securely send data from the local client to the remote server. It is analogous to the SSH and SCP in Linux.
Towards multi-resolution analysis with wavelet transform
We will learn the basic concepts of wavelet tranform and multi-resolution analysis starting from the Fourier Transform, and Gabor Transform.
Empirical orthogonal function analysis to inspect the spatial coherency in the geospatial data (codes included)
Empirical Orthogonal Functions analysis decomposes the continuous space-time field into a set of orthogonal spatial patterns along with a set of associated u...
Concatenating daily seismic traces into one miniseed file (codes included)
I concatenate the daily seismic traces for 15 days into one miniseed file for further analysis. Then I obtained the spectrogram of the 15 days seismic data. ...
Computing cross-correlation and spectrogram of two seismic traces (codes included)
Read the seismic traces from the miniseed files and compute the cross-correlation and spectrogram
Principal component analysis to decompose signals and reduce dimensionality (codes included)
Use Principal Component Analysis (via SVD) to decompose a space-time signal into a few dominant modes and reduce its dimensionality, with Python code.
Signal denoising using fourier analysis in python (codes included)
We will learn the basics of Fourier analysis and implement it to remove noise from the synthetic and real signals
Analyzing miniseed seismic data in matlab (codes included)
We will learn how to convert a mseed data file into mat format and then read and analyze it using MATLAB
