We consider the design of a barrier regulator - a special regulator, which tries to minimize the effect of state-space constraints violation in dynamical systems, creating a soft barrier in their state space. We employ a time-suboptimal predictive control strategy for discrete-time linear systems based on the minimization of a polyhedral distance function. Computationally, our approach reduces to the on-line solution of linear programming problems.

In this paper we consider a time-invariant system of differential equations with an equilibrium. We study the problem of a class of Lyapunov functions allowing to describe an estimation of the domain of attraction (DOA). This work is a development of the results obtained by V. I. Zubov. The solution of the problem is based on the application of the second method of Lyapunov. An example illustrates the theoretical results.

The problem of modelling a uniform depth fluid flow, which generated by hydrodynamic source and sink, is considered. The solution of the appearing linear boundary-value problem is obtained using operator technique and Laplace transform. In the special case, when the hydrodynamic system intensity varies harmonically, an analytical formula for the wave surface elevation was obtained.

In modern literature, the geometric integration means numerical integration of differential equations that provides an accurate preservation of one or more “geometric” properties within rounding error. Among these properties we have to mention first conservation of energy, of momentum, of angular momentum, of volume of the phase space, of time-reversal symmetry, of symplectic structure (volume conservation) etc. In this article we consider the concept of geometrical integration using Lie transformations generated by dynamical system on the one hand, and matrix representation for corresponding evolution operators on the other hand. Examples of solutions for some test problems and of practical problems are given.

We introduce a model of evolutionary game dynamics for partition games - general class of resource allocation games. Our focus is on a computer modelling of the repeated partition games where the pure payoff matrix strategies are the actors of the population. At each instant, actor from one concurrent population is randomly matched with actor from other population, and they play a strategic form game Lotto. The payoffs of the game are population's fitness level. Populations with the strategies that have higher payoffs expand and those that have lower payoffs shrink. We discuss several experimental results with unexpected populations behavior.

The mechanical models of the blood flow in the vessels with complicated forms are proposed. Four kinds of vessel pathologies are considered and simulated by means of FEM in the ABAQUS software application. The governing equations for Non-Newtonian liquid were derived and the semi-slip boundary condition was formulated for fluid-structure interaction. As a result of computer simulation the velocity and pressure distributions were obtained for pathological regions of vessels.

The influence of the surface stress on the local buckling of an infinite plate with a circular nanohole under the uniaxial remote tension is investigated. The critical (Euler) load corresponding to the buckling is found with the Ritz method in the framework of the linearized von Kármán set of equations. Numerical computations are performed with the Ritz method for various elastic properties of the surface. It is shown that one doesn't get a significant correction of the local buckling (i.e of the critical load), if residual surface stress is included into the mathematically exact theory of surface elasticity.
