The problem is reduced to evaluating properties of a fractal set built on a self-affine profile. Numerical simulations are used to generate both support and different amounts of dispersed atoms. Three different parameters (local and global fractal dimension and roughness exponent) are used to analyze profiles obtained by three different processes. Results indicate that the quantitative characterization of dispersed atoms follows from the direct evaluation of the local fractal dimension. This, in turn, is achieved after a simple adaptation of an optimized box-counting algorithm.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-04T11:04:08Z No. of bitstreams: 1 Andrade.pdf: 95518 bytes, checksum: 01a85cb82e678ce85a7a609607adde33 (MD5)Made available in DSpace on 2013-01-04T11:04:08Z (GMT).
