This theory applies to time and length scales which are neither microscopic nor macroscopic. Thus, in these intermediated scales a wide variety of systems (non-aged systems) are properly described. MNET is based on the Gibbs-entropy functional postulate and the conservation of probability. This fact enables us to describe the dynamics of the system in terms of Fokker-Planck equations. As an application, the negative viscosity effect in ferrofluids is analyzed5 p.application/pdfengcc-by-nc-nd (c) Rejano, 2018http://creativecommons.org/licenses/by-nc-nd/3.0/es/Mecànica estadística del no equilibriFenòmens mesoscòpics (Física)Treballs de fi de grauNonequilibrium statistical mechanicsMesoscopic phenomena (Physics)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
