On the use of fractional Brownian motion simulations to determine the 3D statistical properties of interstellar gas

open access: yes, 2003
Based on fractional Brownian motion (fBm) simulations of 3D gas density and velocity fields, we present a study of the statistical properties of spectro-imagery observations (channel maps, integrated emission, and line centroid velocity) in the case of ...

Analysis of self--averaging properties in the transport of particles through random media

open access: yes, 1994
We investigate self-averaging properties in the transport of particles through random media. We show rigorously that in the subdiffusive anomalous regime transport coefficients are not self--averaging quantities.
