In this study, we proposed a novel method for extracting the instantaneous respiratory rate
(IRR) from the pulse oximeter photoplethysmogram (PPG). The method was performed in …

The diagnosis of train bearing defects plays a significant role to maintain the safety of
railway transport. Among various defect detection techniques, acoustic diagnosis is capable …

Conventional time–frequency analysis methods can characterize the time–frequency pattern
of multi-component nonstationary signals. However, it is difficult to detect weak components …

Rolling bearing health condition evaluation under time-varying operating speed requires
information about shaft rotational speed. However, it is not always feasible to install a sensor …

Tacholess order tracking method is an effective tool for condition monitoring of planetary
gearbox under varying-speed operation to reduce the measurement cost and avoid the …

An application of the continuous wavelet transform to modulation extraction of additive moiré
fringes and time-average patterns is proposed. We present numerical studies of the …

Large high-speed wave-piercing catamarans are subject to continuous wave induced hull
vibrations during their lifetime of operation. In severe sea conditions, the vessel experiences …

The detection of railroad roller bearing defects is of great importance for railway traffic. The
acoustic defective bearing detector (ADBD) via a trackside acoustic detection system (TADS) …

Rotational speed of a reference shaft is the key information for planetary gearbox condition
monitoring under nonstationary conditions. As the time‐variant speed and load of planetary …
