Average dynamical frequency behaviour for multi-area islanded micro-grid networks
A micro-grid is a part of power system which able to operates in grid or
islanding mode. The most important variable that able to give us information about the stability in islanded micro-grid network is the frequency dynamical responses. The…

Classification of EEG signals for facial expression and motor execution with deep learning
Recently, algorithms of machine learning are widely used with the field of
electroencephalography (EEG) brain-computer interfaces (BCI). The
preprocessing stage for the EEG signals is performed by applying the
principle component analysis (PCA)…
