DOI: 10.1038/s41598-021-97384-3
Abstract: Periodic structures exhibit unique band gap characteristics by virtue of which they behave as vibro-acoustic filters thereby allowing only waves within a certain frequency range to pass through. In this paper, lateral and vertical flexural… read more here.

DOI: 10.1109/tits.2022.3174884
Abstract: Railway track is never perfect, as rail distortions, namely, geometric irregularities, exist at all locations along the track. However, these distortions can be regarded as valuable indicators for train localization, since track irregularities present location-dependent… read more here.
