A (reactive) lattice-gas approach to economic cycles

A (reactive) lattice-gas approach to economic cycles

A microscopic approach to macroeconomic features is intended. A model for macroeconomic behavior under heterogeneous spatial economic conditions is reviewed. A birth-death lattice gas model taking into account the influence of an economic environment on the fitness and concentration evolution of economic entities is numerically and analytically examined. The reaction-diffusion model can be also...

Polymer gas approach to N - body lattice

We give a simple proof, based only on combinatorial arguments, of the Koteck y-Preiss condition for the convergence of the cluster expansion. Then we consider spin systems with long range, N body interactions. We prove directly, using polymer gas representation, that the pressure may be written in terms of an absolutely convergent series uniformely in the volume, when the interaction is summabl...

A New Approach to Buckling Analysis of Lattice Composite Structures

Buckling strength of composite latticed cylindrical shells is one of the important parameters for studying the failure of these structures. In this paper, new governing differential equations are derived for latticed cylindrical shells and their critical buckling axial loads. The nested structure under compressive axial buckling load was analyzed. Finite Element Method (FEM) was applied to mode...

Spontaneous Nucleation in a Reactive Lattice Gas Automaton

An object oriented approach to lattice gas modeling

We present a parallel library which can be used for any lattice gas (LG) application. A highly reusable implementation, as well as a general parallelization scheme, based on a graph partitioning technique are developed. We show that the performance we obtain with our approach compares favorably with the plain, classical implementation of LG models on regular domains and can be even better for i...
