Time-fractional generalized fifth-order KdV equation: Lie symmetry analysis and conservation laws

Frontiers in Physics, 2023
The purpose of this study is to apply the Lie group analysis method to the time-fractional order generalized fifth-order KdV (TFF-KdV) equation. We examine applying symmetry analysis to the TFF-KdV equation with the Riemann–Liouville (R–L) derivative ...

Time-frequency feature extraction for classification of episodic memory

EURASIP Journal on Advances in Signal Processing, 2020
This paper investigates the extraction of time-frequency (TF) features for classification of electroencephalography (EEG) signals and episodic memory. We propose a model based on the definition of locally stationary processes (LSPs), estimate the model ...
