In many practical systems, acoustic radiation control on noise sources contained within a finite volume by an acoustic enclosure is of great importance, but difficult to be accomplished at low frequencies due to the enhanced acoustic-structure interaction.In this work, we propose to use acoustic metamaterials as the enclosure to efficiently reduce
Introduction: Sleep disturbances are associated with various anxiety- and trauma-related disorders, and specifically with post-traumatic stress disorder (PTSD).Two of the core symptoms of PTSD are recurrent distressing dreams about the traumatic event and difficulty in falling or staying asleep (insomnia).Sleep is essential for functioning, with po
Pseudomonas aeruginosa is an opportunistic Avena Sativa (Wild Oats) pathogen responsible for nosocomial infections, and is often involved in airway infections of cystic fibrosis (CF) patients.P.aeruginosa virulence is related to its ability to form biofilm, trigger different types of motilities, and produce toxins (for example, bacterial pigments).
The rapid transition towards an inverter-dominated power system has reduced the inertial response capability of modern power systems.As a solution, inverters are equipped with control strategies, which can emulate inertia by exchanging power with the grid based on frequency changes.This paper discusses the various current control techniques Axe Acc
