DOI: 10.1007/s13349-021-00503-x
Abstract: Ambient vibration is an unknown excitation source that may produce stationary or non-stationary signals. Under such circumstances, traditional feature extraction techniques may not yield relevant features to damage and not provide reliable results of damage… read more here.
