A Refined Composite Multivariate Multiscale Fuzzy Entropy and Laplacian Score-Based Fault Diagnosis Method for Rolling Bearings

open access: yesEntropy, 2017
The vibration signals of rolling bearings are often nonlinear and non-stationary. Multiscale entropy (MSE) has been widely applied to measure the complexity of nonlinear mechanical vibration signals, however, at present only the single channel vibration ...

Error Estimates for the Heterogeneous Multiscale Finite Volume Method of Convection-Diffusion-Reaction Problem

open access: yesComplexity, 2018
Based on the heterogeneous multiscale method, this paper presents a finite volume method to solve multiscale convection-diffusion-reaction problem. The paper constructs an algorithm of the optimal order convergence rate in H1-norm under periodic medias.

Detecting Arctic Icebergs in Sea Ice in L-Band SAR Images Using a Multiscale CFAR Algorithm

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study proposes a multiscale extension of the well-known constant false alarm rate (CFAR) outlier detection method for the detection of icebergs in L-band synthetic aperture radar (SAR) images. The proposed method offers the possibility to accurately
