Nonequilibrium equalities in absolutely irreversible processes. [PDF]
Physical Review E, 2014 We generalize nonequilibrium integral equalities to situations involving absolutely irreversible processes for which the forward-path probability vanishes and the entropy production diverges, rendering conventional integral fluctuation theorems ...

On the passivity based control of irreversible processes: A port-Hamiltonian approach
Automatica, 2016 Irreversible port-Hamiltonian systems (IPHS) have recently been proposed for the modelling of irreversible thermodynamic systems. On the other hand, a classical result on the use of the second law of thermodynamics for the stabilization of irreversible ...

OPTIMAL PROCESSES IN IRREVERSIBLE THERMODYNAMICS AND MICROECONOMICS [PDF]
Interdisciplinary Description of Complex Systems, 2004 This paper describes general methodology that allows one to extend Carnot efficiency of classical thermodynamic for zero rate processes onto thermodynamic systems with finite rate.

Time irreversibility and amplitude irreversibility measures for nonequilibrium processes [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2021 Time irreversibility, which characterizes nonequilibrium processes, can be measured based on the probabilistic differences between symmetric vectors. To simplify the quantification of time irreversibility, symmetric permutations instead of symmetric vectors have been employed in some studies.

Patterning, From Conifers to Consciousness: Turing’s Theory and Order From Fluctuations
Frontiers in Cell and Developmental Biology, 2022 This is a brief account of Turing’s ideas on biological pattern and the events that led to their wider acceptance by biologists as a valid way to investigate developmental pattern, and of the value of theory more generally in biology.

Towards a Universal Measure of Complexity
Entropy, 2020 Recently, it has been argued that entropy can be a direct measure of complexity, where the smaller value of entropy indicates lower system complexity, while its larger value indicates higher system complexity. We dispute this view and propose a universal

Journal of Physics A: Mathematical and Theoretical, 2020 The equations of reversible (inviscid, adiabatic) fluid dynamics have a well-known variational formulation based on Hamilton’s principle and the Lagrangian, to which is associated a Hamiltonian formulation that involves a Poisson bracket structure ...

More Stages Decrease Dissipation in Irreversible Step Processes
Entropy, 2023 The dissipation in an irreversible step process is reduced when the number of steps is increased in any refinement of the steps in the process. This is a consequence of the ladder theorem, which states that, for any irreversible process proceeding by a ...
