Dynamic bond percolation model
Web1.1. The ordinary percolation model In the standard percolation model, we take an infinite connected locally finite graph G, fix p ∈ [0,1] and let each edge (bond) of G be, independently of all others, open with probability p and closed with probability 1−p. Write π p for this product measure. In percolation theory, one studies the ... WebA dynamic bond percolation model is defined and studied. The model is intended to describe diffusion of small particles (ions, electrons) in a medium which is statistically …

WebOur recently-developed dynamic bond percolation model is extended and applied to polymer electrolytes by assuming an approximate form for the relaxation of the carrier mean-square displacement to its asymptotic value below the percolation threshold, with similar assumptions for the short-range motion of the ionic charges bound to the polymer host.
WebDec 1, 1983 · We have developed a dynamic bond percolation (DBP) model to describe ionic conductivity in these materials. The DBP model is based on a master equation describing ion hops among sites. The percolation aspects are included by making the bonds between sites randomly open or closed. The dynamical aspect is due to the … WebSep 1, 2004 · Favier (2004) developed an isotropic bond percolation model of fire spread in which two time-related parameters, medium ignitability (the time needed for the medium to ignite) and site ...

If the medium is a set of regular lattice points, then there are two main types of percolation: A site percolation considers the lattice vertices as the relevant entities; a bond percolation considers the lattice edges as the relevant entities. These two models …
WebThe authors introduce the cumulant method into the context of position-space renormalisation group. The advantage of this method over previous procedures is that one need not systematically evaluate all 2N states of each Kadanoff cell, where N is the number of elements (sites or bonds) in the cell. They illustrate this method by calculating, for …
