Influence of Rotations on the Critical State of Soil Mechanics
Influence of Rotations Critical State of Soil Mechanics
2010/11/25
The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modi es the fo...
Modelling the outer radiation belt as a complex system in a self-organised critical state
outer radiation belt complex system self-organised critical state
2009/11/11
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of meas...
Anomalies of critical state in fracturing geophysical objects
Anomalies critical state geophysical objects
2009/11/2
Non-linear time-sequences of fracture-related events were studied in drifting sea-ice and fracturing rock. A reversible drop of the b-value was detected prior to the large-scale sea-ice cover fragment...
Critical State Models for Intergrain Junctions of Polycrystalline Superconductors by Third Harmonic ac Susceptibility Measurements
Low field Josephson junction Critical state models
2010/4/9
High harmonic response of high-Tc and Chevrel-phase polycrystalline superconductors are measured in the presence of small ac excitation field and dc magnetic field applied on it. The aim of this work ...
