Journal ArticleDOI
The mechanism of stochastic resonance
TL;DR: In this paper, it was shown that a dynamical system subject to both periodic forcing and random perturbation may show a resonance (peak in the power spectrum) which is absent when either the forcing or the perturbations is absent.
Journal ArticleDOI
The lattice Boltzmann equation: theory and applications
TL;DR: The basic elements of the theory of the lattice Boltzmann equation, a special lattice gas kinetic model for hydrodynamics, are reviewed in this paper, together with some generalizations which allow one to extend the range of applicability of the method to a number of fluid dynamics related problems.
Journal ArticleDOI
Extended self-similarity in turbulent flows
TL;DR: Extended self-similarity (ESS) holds at high as well as at low Reynolds number, and it is characterized by the same scaling exponents of the velocity differences of fully developed turbulence.
Journal ArticleDOI
Lattice Gas Dynamics with Enhanced Collisions
TL;DR: In this article, an efficient strategy for building suitable collision operators to be used in a simplified version of the lattice gas Boltzmann equation was developed, which was applied to the computation of the flow in a channel containing a periodic array of obstacles.
Journal ArticleDOI
Stochastic resonance in climatic change
TL;DR: In this article, an amplification of random perturbations by the interaction of nonlinearities internal to the climatic system with external, orbital forcing is found, and this stochastic resonance is investigated in a highly simplified, zero-dimensional climate model.
