An individual based model with global competition interaction: fluctuations effects in pattern formation
E. Brigatti, V. Schwammle, Minos A. Neto
We present some numerical results obtained from a simple individual based model that describes clustering of organisms caused by competition. Our aim is to show how, even when a de…
Different topologies for a herding model of opinion
V. Schwammle, M. C. Gonzalez, A. A. Moreira +2
Understanding how opinions spread through a community or how consensus emerges in noisy environments can have a significant impact on our comprehension of social relations among in…
Speciational view of macroevolution: are micro and macroevolution decoupled?
V. Schwammle, E. Brigatti
We introduce a simple computational model that, with a microscopic dynamics driven by natural selection and mutation alone, allows the description of true speciation events. A stat…
Breeding and Solitary Wave Behavior of Dunes
O. Duran, V. Schwaemmle, H. Herrmann
Beautiful dune patterns can be found in deserts and along coasts due to the instability of a plain sheet of sand under the action of the wind. Barchan dunes are highly mobile aeoli…
A Model of Barchan Dunes Including Lateral Shear Stress
V. Schwaemmle, H. Herrmann
Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and…
