• Percolation — In physics, chemistry and materials science, percolation concerns also the movement and filtering of fluids through porous materials. Examples include the movement of solvents through filter paper (chromatography) and the movement of petroleum… …   Wikipedia

• Conductivity near the percolation threshold — In a mixture between a dielectric and a metallic component, the conductivity σ and the dielectric constant ε of this mixture show a critical behavior if the fraction of the metallic component reaches the percolation threshold.[1] The behavior of… …   Wikipedia

• Forest-fire model — In applied mathematics, a forest fire model is any of a number of dynamical systems displaying self organized criticality. Note, however, that according to Pruessner et al. (2002, 2004) the forest fire model does not behave critically on very… …   Wikipedia

• Clique percolation method — The clique percolation method[1] is a popular approach for analyzing the overlapping community structure of networks. The term network community (also called a module, cluster or cohesive group) has no widely accepted unique definition and it is… …   Wikipedia

• Directed percolation — In statistical physics Directed Percolation (DP) refers to a class of models that mimic filtering of fluids through porous materials along a given direction. Varying the microscopic connectivity of the pores, these models display a phase… …   Wikipedia
