Effect of friction in a toy model of granular compaction
F. Ludewig, S. Dorbolo, N. Vandewalle
We proposed a toy model of granular compaction which includes some resistance due to granular arches. In this model, the solid/solid friction of contacting grains is a key paramete…
Compaction of anisotropic granular materials : experiments and simulations
G. Lumay, N. Vandewalle
We present both experimental and numerical investigations of compaction in granular materials composed of rods. As a function of the aspect ratio of the particles, we have observed…
Multiscale Modeling of Peritectic Reaction Growth
Marcel Ausloos, Rudi Cloots, Nicolas Vandewalle
Peritectic growth of bulk superconducting cuprate perovskite, like YBa2Cu3O7-x has been studied. The microstructure features are recalled. The simplest model giving the best descri…
Networks of equities in financial markets
G. Bonanno, G. Caldarelli, F. Lillo +3
We review the recent approach of correlation based networks of financial equities. We investigate portfolio of stocks at different time horizons, financial indices and volatility t…
