The problem of computer tomography is considered from incomplete projection data with chaotic algorithms for some particular systems of reconstruction. The numerical reconstruction algorithms and numerical simulation results ...

The paper presents simulation of selection elements of portfolio applying the classical Markowitz’s portfolio analysis theory using parallel collective computational environment — cellular automata. The basics of classical ...

Electrodynamics models of the oil and gas equipment that mainly consist of several controlled electric drives mechanisms and autonomous generators are considered. Applications of the model to drilling and pumping drives ...

It is shown on the basis of analysis for electrotechnical model of commutation process in the contact zone of rail accelerator of macrobodies that surface resistivity of electrodes of a contact pair is a necessary condition ...

Some aspects of the principle of optimality [1, p.83] are considered, and a modification is proposed for the derivation of the main functional equations of dynamic programming to demonstrate that those equations are valid ...

Main objective in this paper is to unify results on controllability and observability on time scales and deduce the results of classical theory as a particular case and then resolve the time constraints on concurrency ...

Получение информации о секторе клиентов является для предприятия важным фактором повышения конкурентоспособности. Эффективными средствами при обработке и использовании информации в процессе принятия решений являются методики ...

An algorithm, permitting us to extract iterations belonging to synchronization-free slices and to generate code enumerating sources of such slices and iterations of each slice in lexicographical order is presented. ...

In this paper a multivariate discrete-time, discrete-state stochastic inventory model for perishable items is discussed. This model draws on earlier works by the authors and the fractional thinning operator of Steutel and ...
