The dynamics of far-from-equilibrium ordering processes in multi-component systems, e.g. crystalline solids or fluid mixtures, that are being quenched in temperature is studied by computer-simulation techniques involving Monte Carlo (MC) as well as molecular dynamics (MD) methods. The systems...

Bracket coefficients for polynomials are introduced. These are like specific precision floating point numbers together with error terms. Working in terms of bracket coefficients, an algorithm that computes a Gröbner basis with floating point coefficients is presented, and a new criterion for...

Some results related to the problem of interpolation of n vertical segments (xk, Yk), k = 1,…,n, in the plane with generalized polynomial functions that are linear combinations of m basic functions are presented. It is proved that the set of interpolating functions (if not empty) is bounded in...

Neural networks or connectionist models are massively parallel interconnections of simple neurons that work as a collective system, can emulate human performance and provide high computation rates. On the other hand, fuzzy systems are capable to model uncertain or ambiguous situations that are...

The aim of the present study was to design a computer program for direct measurement of 3-D connectivity density in iliac crest bone sections, as used for conventional histomorphometry. We used the physical disector principle and developed an algorithm for non-linear alignment of the disector...

This article addresses the use of artificial neural networks for vehicle guidance in local maneuvers. As a typical example, the docking or parking of a semi-autonomous robot is studied. In the proposed approach a feed-forward artificial neural network trained by the back-propagation learning...

The oxacyanine Scheibe aggregate is modelled by a two-dimensional cubic nonlinear Schrödinger equation with multiplicative noise, accounting for thermal fluctuations. For a possible choice of the physical parameters collapse of the initial state representing the Möbius-Kuhn coherent exciton...

A simulation model has been developed for robotics grasping of flexible non-rigid materials predicting deformations occurred by the gripping systems. A new concept for the deformations occurred by the gripping forces has been envisaged to reduce the computational cost on parallel grasping...

In this paper we consider the integrability conditions for multi-parametric families of polynomial-non-linear evolution equations with arbitrary parameters as coefficients of differential monomials. These conditions are the necessary ones for the existence of higher-order evolutionary symmetries...

The implementation of artificial neural networks into hardware will only show their true potential since the networks need full parallel processing for real-time applications. By this way neural networks are a genuine challenge to microelectronics: not only many synapses have to be integrated...
