We use three methods to identify power-law scaling of multi-scale log air permeability data collected by Tidwell and Wilson on the faces of a laboratory-scale block of Topopah Spring tuff: method of moments (M). Extended Self-Similarity (ESS) and a generalized version thereof (G-ESS). All three methods focus on <i>q</i>-th-order sample structure functions of absolute incre... https://allfixelectricales.shop/product-category/dryer-filter/
