We have calculated and discussed the probability density distributions of lengths of fuzzy-end segments, i.e. segments the ends of which assume random positions. We performed our calculations for several simple cases in 1, 2 and 3 dimensions: one end

The paper is a molecular dynamics (MD) study of the structure of rarefied and densified lead-silicate glass of the PbSiO3 composition. Simulations have been performed in the constant volume regime for systems with densities of 3 000, 4 000, 5 000, 5

We perform computer simulations of some one-dimensional models of coupled map lattices (CML) with symmetry and diffusive nearest neighbour coupling, to study Ising-type transitions. Such transitions appear to be related to the presence of a dip (mini

We consider some complex-valued solutions of the Navier-Stokes equations in $R^{3}$ for which Li and Sinai proved a finite time blow-up. We show that there are two types of solutions, with different divergence rates, and report results of computer si

The paper studies the asymptotics of the Brownian integrals with paths restricted to a bounded domain of ℝv, when the domain is dilated to infinity. The framework is that of the Bose-Einstein statistics with paths observed within random time interv

Numerical investigations, supported by partial rigorous results suggest that the motion of a tagged particle of mass M on the line ℝ1 colliding with a free gas of particles of mass m in equilibrium is diffusive. It was conjectured that the diffusio

We consider a one-dimensional lattice of expanding antisymmetric maps [−1, 1]→[−1, 1] with nearest neighbor diffusive coupling. For such systems it is known that if the coupling parameter e is small there is unique stationary (in time) state, w

We study by computer simulations the complex solutions of the two-dimensional Burgers equations in the whole plane in absence of external forces. For such model the existence of singularities, corresponding to a divergence of the total energy at a fi

We report some results of computer simulations for two models of random walks in random environment (rwre) on the one-dimensional lattice \(\mathbb{Z}\) for fixed space–time configuration of the environment (“quenched rwre”): a “Markov model

In the paper we present our recent Molecular Dynamics (MD) simulations of the structure of bismuth-germanate (BGO) glasses of x(pBi2 (1!p)Bi2O3)(1!x)GeO2 composition, where x denotes the content of the bismuth oxide in unmodified glasses, and p - the
