Systems with coefficients in a ring are employed for studying the Decoupling Problem for delay-differential systems. Using geometric methods, the existence of dynamic state feedback solutions is completely characterized.

Both the analytical and the finite element method are being used to investigate soil cutting process. The finite element method is adequately contributing to the development of understanding the reality of this phenomenon. This method is used to predict soil stress distribution of different...

As energy costs are one of the main production costs many efforts were made to reduce the energy consumption of greenhouses. One possibility is the development of new control strategies (e.g. wind-dependent control [B.J. Bailey, Wind development control of greenhouse heating, Acta Hort. 174...

The DSMC (direct simulation Monte Carlo) method for rarefied gas dynamics is studied. The behaviour of the underlying stochastic particle system is determined by three main components – the time step between subsequent collisions, the random mechanism for the choice of the collision partners,...

A form of stabilizing feedback law is proposed for a class of delay systems occurring frequently in practice. It makes use of predictor forms elaborated with distributed delays. Two examples are examined and a procedure for single-input, single-output systems is given. A comparison with other...

The phenomenon of synchronization of a two-dimensional discrete dynamical system is studied for the model of an economic duopoly game, whose time evolution is obtained by the iteration of a noninvertible map of the plane. In the case of identical players the map has a symmetry property that...

In this work a Monte Carlo approach to the electron-phonon quantum transport is presented and studied. It is shown that the Monte Carlo method can be applied for solving quantum transport equations. Numerical results are also presented

New simulation software combines Editor Windows for convenient modeling and file manipulation with a Command Window that automatically switches to full-screen color graphics while a simulation runs. Under Windows 95, the new program preempts the CPU, so that Windows does not compromise solution...

In this paper a second degree iterative Monte Carlo method for solving systems of linear algebraic equations and matrix inversion is presented. Comparisons are made with iterative Monte Carlo methods with degree one. It is shown that the mean value of the number of chains N, and the chain length...

In this paper, it is pointed out that the 2 disk mixed sensitivity problem fails to cover the fatal control performance in time delay systems. The 3 disk mixed sensitivity problem is introduced and an iterative method is proposed to yield a solution to the problem effectively.
