Granular materials composed of particles with differing grain sizes, densities, shapes, or
surface properties may experience unexpected segregation during flow. This review focuses …

Since the subject of traffic dynamics has captured the interest of physicists, many surprising
effects have been revealed and explained. Some of the questions now understood are the …

Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still
challenge engineers and fascinate researchers. This book provides the state-of-the-art of the …

Spontaneous generation of complex order in apparently simple systems is both arresting
and potentially useful,,,,,,,,,,. Here we describe the appearance of complex, ordered …

Starting with a short review of the available literature in the field of pedestrian and
evacuation research, an overview is given over the observed collective phenomena in …

Computer Simulations belong to the most important methods for the theoretical investigation
of granular materials. The present book is intended to serve as an introduction to the field …

The contact between spheres results in a rolling resistance due to elastic hysteresis losses
or viscous dissipation. This resistance is shown to be important in the three-dimensional …

Although pedestrians have individual preferences, aims, and destinations, the dynamics of
pedestrian crowds is surprisingly predictable. Pedestrians can move freely only at small …

Granular materials are ubiquitous in our daily lives. While they have been the subject of
intensive engineering research for centuries, in the last two decades granular matter has …

▪ Abstract Granular materials segregate. Small differences in either size or density lead to
flow-induced segregation, a complex phenomenon without parallel in fluids. Modeling of …
