Description

In physics, chemistry and materials science, percolation concerns the movement and filtering of fluids through porous materials. During the last three decades, percolation theory, an extensive mathematical model of percolation, has brought new understanding and techniques to a broad range of topics in physics, materials science as well as geography.

    Online Presentations | 04 Nov 2008 | Contributor(s):: Muhammad A. Alam

    Even a casual review of modern electronics quickly convinces everyone that randomness of geometrical parameters must play a key role in understanding the transport properties. Despite the diversity of these phenomena however, the concepts percolation theory provides a broad theoretical framework...

    Online Presentations | 04 Nov 2008 | Contributor(s):: Muhammad A. Alam

    Three basic concepts of the percolation theory – namely, percolation threshold, cluster size distribution, and fractal dimension – are defined and methods to calculate them are illustrated via elementary examples. These three concepts will form the theoretical foundation for discussion in Lecture...
