Small-scale wind energy harvesting using piezoelectric materials
Published 2015“…A two degree-of-freedom galloping piezoelectric energy harvester (GPEH) is proposed which successfully enhances the output power in low wind speeds. A beam stiffener is employed as an electromechanical coupling magnifier, which is proved to be an easy but greatly effective efficiency enhancing method for energy harvesting from VIV, flutter as well as galloping. …”

Maneuvering angle rigid formations with global convergence guarantees
Published 2023“…Angle rigid multi-agent formations can simultaneously undergo translational, rotational, and scaling maneuvering, therefore combining the maneuvering capabilities of both distance and bearing rigid formations. However, maneuvering angle rigid formations in 2D or 3D with global convergence guarantees is shown to be a challenging problem in the existing literature even when relative position measurements are available. …”
