Hybrid Time and Time-Frequency Blind Source Separation Towards Ambient System Identi cation of Structures
(University of Waterloo, 2010-08-24)
Blind source separation methods such as independent component analysis (ICA) and second order blind identification (SOBI) have shown considerable potential in the area of ambient vibration system identification. The objective ...
Gearbox Fault Detection using Synchro-squeezing Transform
This paper presents a novel fault-detection method for gearbox vibration signatures using synchro-squeezing transform (SST). Premised upon the concept of time-frequency (TF) reassignment, SST provides a sharp representation ...
Novelty Detection in Airport Baggage Conveyor Gear-Motors Using Synchro-Squeezing Transform and Self-Organizing Maps
(Prognostic and Health Management Society, 2013)
A powerful continuous wavelet transform based signal processing tool named Synchro-squeezing transform (SST) has recently emerged in the context of non-stationary signal processing. Founded upon the premise of time-frequency ...
