In pursuit of enhancing the output power of energy harvesters, this paper introduces a novel
jellyfish-inspired bistable piezoelectric-triboelectric hybrid generator (JIB-PTHG) with low …

Blind deconvolution technique can effectively recover the periodic fault impulses. However,
deconvolution algorithms may not perform well for fault detection if the objective criteria are …

Bistable structures, which are capable of oscillating between two stable states, have
garnered significant attention and have been applied in many engineering domains due to …

The quantitative diagnosis of rolling bearings is essential to automating maintenance
decisions. Over recent years, Lempel–Ziv complexity (LZC) has been widely used for the …

Although stochastic resonance (SR) has been widely used to enhance weak fault signatures
in machinery and has obtained remarkable achievements in engineering application, the …

This paper analyses the stochastic resonance of a double delay-controlled nonlinear system
based on the high-order-degradation potential function. It provides a theoretical derivation of …

Bearings play an important role in the rotating machinery. Timely fault detection and
maintenance can prevent catastrophic incidents caused by bearing faults. As one of the …

Stochastic resonance (SR), as a signal processing method that is able to use noise to
enhance weak periodic signals, provides effective technical support for the detection of …

This paper proposes a ship-radiated noise (S-RN) detection method based on fractional-
order Duffing coupled Van der Pol oscillator (FODVP) for detecting unknown signal …

The spindle bearing of a circulation fan is an important component of a cement grinding
machine. In addition to the faults on the spindle bearing, impeller wear and ash …
