Abstract: Abstract Sound radiation from a vibrating enclosure into an enclosed space can be actively reduced using sensors and actuators attached to the enclosure. However, the sound cannot be effectively reduced by merely minimizing the structural… read more here.

Abstract: Abstract In recent years, blind source separation (BSS) has gained significant interest in the context of operational modal analysis, as a non-parametric alternative to the identification of mechanical structures from output-only measurements. One persisting limitation… read more here.
