In this contribution, particle size distributions (PSD) of soil samples are analyzed by fractal methods. Different scaling domains, characterizing different ranges of particle sizes, are identified. Numerical models based on cellular automata are presented with the aim to understand the basic...

Experiments in which thick clay plates and glass rods are fractured have revealed different behavior of fragment mass distribution function in the small and large fragment regions. In this paper we explain this behavior using non-extensive Tsallis statistics and show how the crossover between...

New large time asymptotic (self-similar) solutions of the fragmentation (breakage) equation are derived in closed form … for the case of certain homogeneous discrete fragmentation kernel. A fragmentation kernel is called homogeneous and … fragmentation kernel is not a continuous function. The present solutions are the first explicit self-similarity distributions for …

Two models of binary fragmentation are introduced in which a time-dependent transition size produces two regions of … fragment sizes above and below the transition size. In the models, we consider a fixed rate of fragmentation for the largest … fragment and two different rates of fragmentation for the two regions of sizes above and below the transition size. The models …

We consider the dynamics of a biological population described by the Fisher–Kolmogorov–Petrovskii–Piskunov (FKPP) equation in the case where the spatial domain consists of alternating favorable and adverse patches whose sizes are distributed randomly. For the one-dimensional case we define...
