In order to study the relationship between the deformation mechanism and permeability on brittle rock, the curves of stress–strain and permeability–strain of brittle rock were analyzed, the results indicated that the permeability of brittle rock increased rapidly at the critical failure...

The dynamic scaling properties of growing surfaces with point-defects have been studied by applying a dynamic renormalization-group approach to the generalized KPZ equation, which contains a growth inhomogeneity term of delta function. It can be shown, from the roughness exponent χ and dynamic...

The renormalization in real space of systems with nonlocal degrees of freedom is discussed and reviewed for the percolation model, for which the degrees of freedom, the clusters, are nonlocal and span all ranges in the system. Previous attempts, including recent ones, are critically examined and...
