Abstract: Abstract This study examines hydrogeotechnical processes governing sandy beach–bluff recession under wave action, emphasizing material composition effects. Flume experiments compared large-scale bluffs composed of densified ...

Abstract: AbstractVertical takeoff and landing (VTOL) fixed-wing hybrid unmanned aerial vehicle is currently the most noteworthy and practical solution for VTOL fixed-wing aircraft. However, several issues persist in existing electric ...

Abstract: Scavenging mechanical energy from the deformation of roadways using piezoelectric energy transformers has been intensively explored and exhibits a promising potential for engineering applications. We propose here a new ...
