Theoretical Analysis of Vuilleumier’s Hypothetical Engine and Cooler
Energies, 2021 Vuilleumier machines are a promising technology for heating. Respective performances of Vuilleumier’s engine and cooler are generally unclear. In Stirling machines, performances can be determined based on PV power flow and heat flow methods. In this work,

Optimizing thermodynamic trajectories using evolutionary and gradient-based reinforcement learning [PDF]
, 2019 Using a model heat engine, we show that neural network-based reinforcement learning can identify thermodynamic trajectories of maximal efficiency. We consider both gradient and gradient-free reinforcement learning.

Business Strategy and the Environment, EarlyView.ABSTRACT Cooperatives as a democratic form of economic organization are an emerging focus in research on the social dimensions of circular economy. However, there is no international database on cooperatives and circular economy, impeding systematic analysis.
