Abstract: A unified method is proposed for screening the ground-transmitted vibrations generated by machine foundations. The method is based on the solid-state phenomenon of Bragg resonance, which leads to the fact that periodic ...

Abstract: The mode-localization phenomenon is here proposed as a mechanism for suppressing undesired oscillations of trusses. Sample trusses consisting of repeated unit cells are designed to have weak intermediate member(s) in ...

Abstract: Because leaks tend to form at joints or welds at the intersection of modular pipes, the occurrence of multiple leaks in a long pipeline is possible. In this study, a multiple-leak detection methodology using an acoustic ...
