IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022 Among patients with cervical myelopathy, the most common level of stenosis at spinal cord of all ages was reported to be between cervical levels C5-6. Previous studies found that time-frequency components (TFCs) of somatosensory evoked potentials (SEPs ...

Impulse Feature Extraction of Bearing Faults Based on Convolutive Nonnegative Matrix Factorization
IEEE Access, 2020 The detection of bearing faults is of great significance for the stable operation of rotating machinery. Apart from detection by analysing the vibration response, another powerful strategy is to extract the periodic impulse excitation directly induced by

A New Perspective of Wind Power Grid Codes Under Unbalanced and Distorted Grid Conditions
IEEE Access, 2020 Increasing penetration of wind power has led power system operators worldwide to develop new grid codes for integration of a wind power plant (WPP) onto the grid. According to the grid codes issued by Federal Energy Regulatory Commission (FERC) in the US,

A new positive time-frequency distribution [PDF]
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002 This article studies the formulation of new members of the Cohen-Posch (1985) class of positive time-frequency energy distributions. Members of this class are always positive functionals and satisfy the marginal constraints. Therefore, they can be properly interpreted as distributions.

Time-Frequency Analysis of Systems with Changing Dynamic Properties [PDF]
, 2006 The Wigner-Ville Distribution, and related refinements, represent a class of advanced time-frequency analysis tools that are distinguished from Fourier and wavelet methods by an increase in resolution in the time frequency plane. Time-frequency analysis

A Deep Learning Framework for Decoding Motor Imagery Tasks of the Same Hand Using EEG Signals
IEEE Access, 2019 This study aims to increase the control's dimensions of the electroencephalography (EEG)-based brain-computer interface (BCI) systems by distinguishing between the motor imagery (MI) tasks associated with fine body-parts of the same hand, such as the ...
