On the Second Law of thermodynamics and the piston problem [PDF]
, 2003 The piston problem is investigated in the case where the length of the cylinder is infinite (on both sides) and the ratio $m/M$ is a very small parameter, where $m$ is the mass of one particle of the gaz and $M$ is the mass of the piston. Introducing initial conditions such that the stochastic motion of the piston remains in the average at the origin ...

Critical behavior of two freely evolving granular gases separated by an adiabatic piston
, 2010 Two granular gases separated by an adiabatic piston and initially in the same macroscopic state are considered. It is found that a phase transition with an spontaneous symmetry breaking occurs.

Influence of hydraulic brakes typical parameters on the process of recoiling mass breaking
Vojnotehnički Glasnik, 1998 The mathematical model for providing typical parameters of the process of breaking of recoiling mass on an artillery gun is presented. The model of hydraulic brakes with some discrete distribution of orifice surfaces in the cylinder is defined.

Validation of the Jarzynski relation for a system with strong thermal coupling: an isothermal ideal gas model [PDF]
, 2006 We revisit the paradigm of an ideal gas under isothermal conditions. A moving piston performs work on an ideal gas in a container that is strongly coupled to a heat reservoir. The thermal coupling is modeled by stochastic scattering at the boundaries. In

On a slow drift of a massive piston in an ideal gas that remains at mechanical equilibrium [PDF]
arXiv, 2003 We consider a heavy piston in an infinite cylinder surrounded by ideal gases on both sides. The piston moves under elastic collisions with gas atoms. We assume here that the gases always exert equal pressures on the piston, hence the piston remains at the so called mechanical equilibrium.
