The last years have witnessed an increasing attention to entropy-based criteria in adaptive systems. Several principles were proposed based on the maximization or minimization of entropic cost functions. We propose a new type of neural network classifiers with multilayer perceptron (MLP) architecture, but where the usual mean square error minimization principle is substituted by the minimizatio...

A variational-principle formulation of dissipative magnetohydrodynamics (DMHD) including thermal conduction and viscous dissipation as well as resistive decay is presented. The functional to be minimized is an extension of the generalized entropy-production (GEP) rate first discussed by I. Prigogine [Nonequilibrium Thermodynamics, Variationa! Techniques, and Stability, edited by R. J. Donnelly,...

In this study, the relationship among the concepts of entropy generation rate, entransy theory, and generalized thermal resistance to the optimal design of thermal systems is discussed. The equations of entropy and entransy rates are compared and their implications for optimization of conductive heat transfer are analyzed. The theoretical analyses show that based on entropy generation minimizat...
