Power generation from wind farms is growing rapidly around the world. In the past decade,
wind energy has played an important role in contributing to sustainable development …

Bolted connections have been widely applied in engineering structures, loosening will
happen when bolted connections are subjected to continuous cyclic load, and a significant …

The expansion of cities puts a high demand on water utilities to provide fresh water amidst
global water stress. One of the most challenging issues that continuously menaces water …

Periodic fault impulses, inevitably occurring along with a localized defect, are crucial for
incipient fault diagnosis of rotating machinery. Whereas, they are awfully weak and masked …

Abstract Dispersion Lempel-Ziv complexity (DLZC) has been introduced into the field of
underwater acoustic with great performance, but it only reflects complexity information from …

This paper proposes an intelligent diagnosis method for rotating machinery faults based on
improved variational mode decomposition (IVMD) and CNN to process the rotating …

Digitalization and intellectualization of energy system require the fault information of energy
conversion devices to be captured as accurately as possible from the massive data, so as to …

Aimed at the problem of fault characteristic information bearing vibration signals being easily
submerged in some background noise and harmonic interference, a new algorithm named …

Permutation Lempel-Ziv complexity (PLZC) is a recently proposed method for analyzing
signal complexity. However, PLZC only characterizes the signal complexity from single scale …

The health condition of bearings was related to the operation status of mechanical
equipment, and there were relatively few methods to recognize the severity of bearing faults …
