Multiple threshold percolation in polymer/filler composites

formulae of percolation theory are surprisingly robust, applying even to samplesThe reasonable distribution of percolation thresholds in a sample can lead to a peak in the capacitance versus filler concentration curve at a...

Percolation induced effects in two-dimensional coined quantum walks: analytic asymptotic solutions

-dimensional finite integerlattices with percolation. Based on this theory, we find new tools in quantum information theory. Once we admit random variations in the connectivity of the underlying graph, we arrive at the prob...

Scaling of the anomalous Hall effect in the insulating regime

in metals. Basing our theory on the phonon-assisted hopping mechanism and percolation theory in random networks, we derive a general formula for the anomalous Hallconductivity, in which the percolation theory<...

Percolation Theory and DC Conductivity of CB Dispersed in Polyethylene

Perkolation theory describes the carbon black network formation using the Bethe´s lattice approximation. In could be used for experimental results explanations successfully but the precise electrical conductivity prognosis is problematic. Th...

Monitoring of dry anaerobic fermentation in experimental facility with use of biofilm reactor

This work has succeeded in proving the direct dependency of percolate strategy on biogas production. Thus, the theory from Karafiát and Vítěz's research (2009: project onthe amount of biogas production is the percolation in...

Simulation of two-dimensional fluid transfer in porous media using percolation theory (DUEPERCOL Program)

Two-dimensional fluid transfer in a porous material is simulated using percolation theory. The porous material is represented by a network of interconnected pores. The program addresses the extrusion of liquid from pores by pressure...
