DOI: 10.1007/s00779-019-01337-7
Abstract: Although many studies have attempted to detect the hand postures of a mobile device to utilize these postures as a user interface, they either require additional hardware or can differentiate a limited number of grips… read more here.

DOI: 10.1016/j.bbe.2020.12.007
Abstract: Abstract Manual interpretation of heart sounds is insensitive and prone to subjectivity. Automated diagnosis systems incorporating artificial intelligence and advanced signal processing tools can potentially increase the sensitivity of disease detection and reduce the subjectiveness.… read more here.

DOI: 10.1016/j.firesaf.2021.103431
Abstract: Abstract Although visual signage is the most common means of evacuation support in road tunnels emergencies, these can be of little help when there is dense smoke product of a fire. In such cases, auditory… read more here.

DOI: 10.1017/jfm.2017.811
Abstract: Since the speed of sound in water is much greater than that of the surface gravity waves, acoustic signals can be used for early warning of tsunamis. We simplify existing works by treating the sound… read more here.

DOI: 10.3390/bioengineering10060645
Abstract: The intelligent classification of heart-sound signals can assist clinicians in the rapid diagnosis of cardiovascular diseases. Mel-frequency cepstral coefficients (MelSpectrums) and log Mel-frequency cepstral coefficients (Log-MelSpectrums) based on a short-time Fourier transform (STFT) can represent… read more here.
