Abstract: Time-frequency (TF) analysis (TFA) is a vital tool for processing nonstationary signals. Synchro-squeezing transform (SST) and synchro-extracting transform (SET) are two important TFA tools, but they are defective in terms of sharpening performance or reconstruction… read more here.

DOI: 10.1109/tim.2022.3186706
Abstract: Time–frequency analysis (TFA) methods can characterize the instantaneous frequency (IF) features of nonstationary signals by constructing the time-domain signal model. However, the traditional TFA methods are ineffective for transient signals that are discontinuous in the… read more here.

DOI: 10.3390/app13095717
Abstract: To conduct the ultrasonic weld inspection of polyethylene pipes, it is necessary to use low-frequency transducers due to the high sound energy attenuation of polyethylene. However, one of the challenges in this process is that… read more here.
