Repulsive Casimir Pistons [PDF]
, 2006 Casimir pistons are models in which finite Casimir forces can be calculated without any suspect renormalizations. It has been suggested that such forces are always attractive. We present three scenarios in which that is not true.

Design and optimisation of cushioning structure of hydraulic free-piston engine
The Journal of Engineering, 2018 The velocity of the free-piston assembly (FPA) of the hydraulic free-piston engine (HFPE) is very high, which is up to 10 m/s. In order to avoid the collision of the FPA to the cylinder head when the FPA moves towards the dead centres, the cushioning ...
