Auxetic behaviour in crystals of hard polyhedra
Rinske M. Alkemade, Silvana A. Caipa Cure, Alptuğ Ulugöl +8
Auxetic materials - systems that, when subjected to a compression in one direction, also compress in one or more perpendicular directions - have intrigued researchers for decades d…
Optimal Control of an Electromechanical Energy Harvester
Dario Lucente, Alessandro Manacorda, Andrea Plati +2
Many techniques originally developed in the context of deterministic control theory have been recently applied to the quest for optimal protocols in stochastic processes. Given a s…
Control of friction: shortcuts and optimization for the rate- and state-variable equation
Andrea Plati, Alberto Petri, Marco Baldovin
Frictional forces are a key ingredient of any physical description of the macroscopic world, as they account for the phenomena causing transformation of mechanical energy into heat…
Shear profile in a dense packing of large grains
Alessio Quaresima, Andrea Plati, Andrea Gnoli +1
We investigate the shear of a dense bed of refracting supermillimetric grains confined within a transparent horizontal annular cell with a rotating top. The local time correlation…
