DOI: 10.1016/j.ijleo.2021.166357

Abstract: Abstract The fractional Fourier transform (FRFT) has been shown to be powerful tool for optics and signal processing. However, it fails in locating the fractional domain frequency contents which is required in some applications. In… read more here.

DOI: 10.1016/j.jastp.2020.105477

Abstract: Abstract In this paper, the wavelet packet transform (WPT) is applied to analyze the time-frequency features of three kinds of lightning events (the cloud pulse, the return stroke and the stepped leader) and a new… read more here.

DOI: 10.3233/shti220632

Abstract: In this work, an attempt has been made to classify arousal and valence states of emotion using time-domain features extracted from the Wavelet Packet Transform. For this, Electroencephalogram (EEG) signals from the publicly available DEAP… read more here.

DOI: 10.7717/peerj-cs.635

Abstract: Concrete is the main material in building. Since its poor structural integrity may cause accidents, it is significant to detect defects in concrete. However, it is a challenging topic as the unevenness of concrete would… read more here.
