Sigmoid-Based Refined Composite Multiscale Fuzzy Entropy and t-SNE Based Fault Diagnosis Approach for Rolling Bearing

Measurement: Journal of the International Measurement Confederation, 2018
Abstract Multiscale fuzzy entropy (MFE) has been taken as a prevalent tool for complexity measure of time series. However, the entropy estimation of MFE is sensitive to the preset parameters and will cause an inaccurate and even undefined entropy when the data is not long enough.

Refined composite multivariate multiscale fuzzy entropy analysis of horizontal oil-water two-phase flow

2017 12th International Conference on Computer Science and Education (ICCSE), 2017
Horizontal oil-water two-phase flow is widely encountered in power plants, chemical engineering and petroleum industry. Understanding the flow characterization of horizontal oil-water two-phase is significant to uncover the flow mechanics underlying oil-water flow, which will facilitate the safety design and optimization of the process engineering and ...
