As a fully distributed sensor, the phase-sensitive optical time domain reflectometer (f-OTDR) has attracted remarkable attention in real-time vibration detection. We present a dual-channel f-OTDR (DC-f-OTDR), formed by two single-channel f-OTDRs (SC-f-OT...

Most of the current research on the diagnosis of rolling bearing faults is based on vibration signals. However, the location and number of sensors are often limited in some special cases. Thus, a small number of non-contact microphone sensors are a subop...

For the image super-resolution method from a single channel, it is difficult to achieve both fast convergence and high-quality texture restoration. By mitigating the weaknesses of existing methods, the present paper proposes an image super-resolution alg...

To improve the performance of single-channel, multi-fault blind source separation (BSS), a novel method based on regenerated phase-shifted sinusoid-assisted empirical mode decomposition (RPSEMD) is proposed in this paper. The RPSEMD method is used to dec...
