Water, 2022 In order to achieve the best performance of a thermal system, two major analyses must be carried out on the system: energy and entropy generation. The best scenario is a mechanism in which the system has minimum entropy generation and the highest Nu ...

Generalized entropy minimization under full marginal constraints
, 2020 We consider the problem of minimizing a generalized relative entropy, with respect to a reference diffusion law, over the set of path-measures with fully prescribed marginal distributions. When dealing with the actual relative entropy, problems of this kind have appeared in the stochastic mechanics literature, and minimizers go under the name of Nelson

Entropy Generation During the Interaction of Thermal Radiation with a Surface
Entropy, 2012 The entropy calculation for radiation fluxes is reviewed and applied to simple radiation-surface interactions. A plate interacting with radiation from a hot object in the zenith of the hemisphere surrounded by a colder atmosphere is analyzed in detail ...

Maximum power, ecological function and efficiency of an irreversible Carnot cycle. A cost and effectiveness optimization [PDF]
, 2007 In this work we include, for the Carnot cycle, irreversibilities of linear finite rate of heat transferences between the heat engine and its reservoirs, heat leak between the reservoirs and internal dissipations of the working fluid. A first optimization

Sparse Signal Recovery via Generalized Entropy Functions Minimization
IEEE Transactions on Signal Processing, 2019 Compressive sensing relies on the sparse prior imposed on the signal of interest to solve the ill-posed recovery problem in an under-determined linear system. The objective function used to enforce the sparse prior information should be both effective and easily optimizable.

Where there is life there is mind: In support of a strong life-mind continuity thesis [PDF]
, 2017 This paper considers questions about continuity and discontinuity between life and mind. It begins by examining such questions from the perspective of the free energy principle (FEP).
