An Entropy Generation Rate Model for Tropospheric Behavior That Includes Cloud Evolution [PDF]
Entropy, 2023 A postulate that relates global warming to higher entropy generation rate demand in the tropospheric is offered and tested. This article introduces a low-complexity model to calculate the entropy generation rate required in the troposphere.

Composability and generalized entropy [PDF]
Physics Letters A, 1999 We address in this paper how tightly the composability nature of systems: $S_{A+B} =Ω(S_A, S_B)$ constrains definition of generalized entropies and investigate explicitly the composability in some ansatz of the entropy form.

ORDERS OF GROWTH AND GENERALIZED ENTROPY [PDF]
Journal of the Institute of Mathematics of Jussieu, 2021 AbstractWe construct the complete set of orders of growth and define on it the generalized entropy of a dynamical system. With this object, we provide a framework wherein we can study the separation of orbits of a map beyond the scope of exponential growth. We show that this construction is particularly useful for studying families of dynamical systems

Analysis of Entropy Generation and Potential Inhibition in an Aeroengine System Environment
International Journal of Aerospace Engineering, 2022 From a system perspective, the entropy generation of an aeroengine is directly related to the thermal efficiency when the Brayton cycle pressure ratio and maximum temperature remain constant.
