Yasir M, Koh B
Sensors (Basel) . 2018 Apr; 18(4). PMID: 29690526
This paper presents the local mean decomposition (LMD) integrated with multi-scale permutation entropy (MPE), also known as LMD-MPE, to investigate the rolling element bearing (REB) fault diagnosis from measured vibration...

Sensors (Basel) . 2017 Nov; 17(11). PMID: 29143772
This study proposes a fault detection and diagnosis method for bearing systems using ensemble empirical mode decomposition (EEMD) based feature extraction, in conjunction with particle swarm optimization (PSO), principal component...

Sensors (Basel) . 2013 Dec; 14(1):283-98. PMID: 24368701
This study presents a fault detection of roller bearings through signal processing and optimization techniques. After the occurrence of scratch-type defects on the inner race of bearings, variations of kurtosis...
