Volcanic eruptions increasingly present catastrophic natural risks with hundreds of millions of people now living in areas of active volcanism and major conurbations around active eruptive centres. Interdisciplinary studies in disaster reduction have an important role in volcanic emergency...

A gas kinetic method for simulating ideal fluids based on the BGK equation is described. The method is extended to model nonideal fluids. The method developed is used to simulate systems described by a Cahn–Hilliard equation coupled to a fluid equation. The results of simulations of binary...

Monte Carlo simulations are used to analyse the behavior of the extended Ashkin-Teller model in two dimensions from the ratio of the square of the second moment of the order parameter to its fourth moment. The critical surface in three dimensional parameter space is calculated in regions where...

An original theoretical model has been devised to simulate mass flow over hill slopes due to gravitational sliding. The sliding mass is discretized into a sequence of contiguous blocks which are subjected to gravitational forces, to bottom friction and to surface resistance stresses that are...

We analyze income tax evasion dynamics in a standard model of statistical me- chanics, the Ising model of ferromagnetism. However, in contrast to previous re- search, we use an inhomogeneous multi-dimensional Ising model where the local degrees of freedom (agents) are subject to a specific...

We describe a newly established research project called SoftLab in the area of computational science and computational engineering. The SoftLab project attempts to link physical laboratory experimentation with computer control and simulation to provide a virtual laboratory for computational...
