COMPLEMENTARY ENSEMBLE EMPIRICAL MODE DECOMPOSITION: A .

The phenomenon of mode-mixing caused by intermittence signals is an annoying problem in Empirical Mode Decomposition (EMD) method. The noise assisted method of Ensemble EMD (EEMD) has not only effectively resolved this problem but also generated a new one, which tolerates the residue noise in the signal reconstruction.

Multi-Fault Detection of Rolling Element Bearings under .

To effectively detect the faults of rolling element bearings under harsh working condition, an IMF-based adaptive envelope order analysis (IMF-AEOA) technique is proposed in this section. The flow chart of the IMF-AEOA is shown in Figure 1, and its principle and implementation are elaborated as follows:
