In this study, nucleation and grain growth was studied by using 2-dimensional generalized Monte Carlo simulations and experiments. As an attempt to improve the JMAK model, we proposed a new differential equation to be able to model nucleation and growth phenomena using nonextensive...

We seek to provide a general strategy to permit the study of non-equilibrium aspects of conformational transitions in various types of heteropolymers. The theoretical methods we have developed rely mainly on the Gaussian self-consistent approach that replaces the exact non-linear Langevin...

The process of multicomponent condensation is considered. The global evolution of a metastable state originally created in the system has been investigated. Kinetic description of the ordinary one channel nucleation has been corrected. The theory taking into account several channels of...

In this paper, explicit method of constructing approximations (the triangle entropy method) is developed for nonequilibrium problems. This method enables one to treat any complicated nonlinear functionals that fit best the physics of a problem (such as, for example, rates of processes) as new...

Based on general principles of metastable states and the mechanics of continuous media, the kinetic equation of settlement of granular material subjected to low level vibration and elastic stresses is developed. Because of confining pressure, the material remained nearly as a solid block and...
