Abstract: Abstract In this study, we experimentally examine the behaviour of a free-falling rigid sphere penetrating a quiescent liquid pool. Observations of the sphere trajectory in time are made using two orthogonally placed high-speed cameras, yielding… read more here.

Abstract: The dynamics of moving solids with unilateral contacts are often modelled by assuming rigidity, point contacts, and Coulomb friction. The canonical example of a rigid rod with one endpoint slipping in two dimensions along a… read more here.

Abstract: This paper is devoted to synthesizing the asymptotically stable arbitrary programmed motion for a rigid body with a cavity entirely filled with viscous fluid. To solve this problem, we synthesize an active program control applied… read more here.
