The reported discrepancy between theory and experiment for external combustion Stirling engines is explained by the addition of thermal resistance of the combustion gasses to the standard Carnot model. In these cases, the Stirling engine ideal efficiency is not as is normally reported equal to the Carnot cycle efficiency but is significantly lower. A new equation for ideal Stirling engine effic...

In this paper, synchronization between two Rössler Chaotic Systems with impulsively controlling is established by using the criteria on uniform equi-boundedness and equi-Lagrange stability for impulsive systems. After several theoretical derivations, some simulation results are given to demonstrate our results.

Shortcuts to adiabaticity constitute a powerful alternative that speed up time evolution while mimicking adiabatic dynamics. In this paper we describe how implement shortcuts for the case of massless scalar field inside cavity with moving wall, in $1+1$ dimensions. The approach is based on known solution problem exploits conformal symmetry, and take place whenever there no dynamical Casimir eff...
