Acoustic vibration characteristics for combined diagnosis of rail corrugation: An application of MCiSSA and permutation heterogeneous recurrence plot

Results in Engineering
In this paper, we utilize acoustic vibration characteristics for the combined diagnosis of rail corrugation. The two-dimensional signal is first decomposed into several modes by Multivariate circulant singular spectrum analysis (MCiSSA) and the ...
