Hierarchical Markovian modeling of multi-time scale systems
M. Abel, K. H. Andersen, G. Lacorata
We present a systematic way to analyze and model systems having many characteristic time-scales. The method we propose is employed for a test-case of a meandering jet model manifes…

A Particle Model of Rolling Grain Ripples Under Waves
K. H. Andersen
A simple model is presented for the formation of rolling grain ripples on a flat sand bed by the oscillatory flow generated by a surface wave. An equation of motion is derived for…

Bursts and Shocks in a Continuum Shell Model
K. H. Andersen, T. Bohr, M. H. Jensen +1
We study a "burst" event, i. e. the evolution of an initial condition having support only in a finite interval of k-space, in the continuum shell model due to Parisi. We show that…
