Extremes | Year: 2017

We study clusters of threshold exceedances caused by dependence in time series. The clusters are defined as conglomerates containing consecutive threshold exceedances of the series separated by return intervals with consecutive non-exceedances. We derive asymptotic distributions of the cluster and inter-cluster sizes for processes with the extremal index equal to zero, the asymptotic expectation of the inter-cluster size and an exponential rate of convergence of the distribution tail of the return interval between clusters to the stable distribution tail. Distributions of the cluster and inter-cluster sizes of ARMAX, MM and AR(1) processes are obtained. © 2017 Springer Science+Business Media New York

In this article we formulate the position of the contextual approach to the requirements to semantic objects of scientific information integration. Terms of the scientific publication are objects. The homogeneous conceptual models are offered for systematization of terms of the scientific publication and an estimation of its semantic integrity. The example of semantic integration of two scientific publications is given. The applied and researched tasks are defined for the formal and semantic integration of scientific information. © 2017 The Authors.

Consideration was given to the model with coupled subsystems. In the absence of relations between the subsystems, the MIS falls down into independent systems of autonomous ordinary differential equations. In the structure of the entire system, the subsystems make up hierarchical levels. Sun-planets- satellites, interacting moving objects, and so on exemplify the models with coupled subsystems. The problem of studying dynamics of such models was posed. The following natural approach to their analysis was proposed: classification of the subsystems by types (dynamic properties), specification of various bundles of subsystems, and subsequent analysis of these bundles. Realization of the approach to oscillations, stability, stabilization, bifurcation, and resonance was given. These problems were solved for the model with coupled subsystems having two second-kind subsystems in the basic combination of the oscillation modes in the subsystem. © 2013 Pleiades Publishing, Ltd.

In this paper, game-theoretic models of social interaction with binary actions of agents are considered. The phenomena of conformity and anti-conformity are briefly analyzed, and a game-theoretic model reflecting them is constructed. In addition, the general game-theoretic model of collective conformity behavior, the model with mutual dominance of agents, the model with reputation, and the model with identical agents are studied. The structure of Nash equilibria and corresponding methods of its evaluation are described for the above-mentioned models. © Pleiades Publishing, Ltd., 2012.

Simulation Modelling Practice and Theory | Year: 2011

The method for dynamic model synthesis and discrete simulation of complex hierarchical control systems is presented. The method provides integration of large data sets, monitoring data and expert knowledge with the process of simulation and analysis of system state dynamics, thus providing an extensible and evolvable environment and reuse of knowledge and simulation models. The method is based on the hierarchical state diagrams technique and control scenarios methodology. The general structure of corresponding computer simulation system is also proposed. We also outline general principles of computer realization of our simulation approach, and schemes of model-based knowledge representation. The proposed method is based on the object-oriented paradigm and is especially powerful in information-intensive environments. © 2010 Elsevier B.V. All rights reserved.

We consider a certain game-theoretic model of non-anonymous threshold conformity behavior over binary action sets of the players. For a given player, non-anonymity implies different level of confidence in the neighbors. The notions of conformity and autonomy are briefly analyzed; the corresponding game-theoretic threshold model is built to describe counteraction of these phenomena. Nash equilibria characterizing the conformity behavior are derived. Finally, characteristic conditions of the Nash equilibria are studied, and structure of the equilibria is described. © Pleiades Publishing, Ltd., 2012.

The synthesis control problem for the plane motion of a wheeled robot with constrained control resource is studied. The goal of the control is to bring the robot to an assigned curvilinear trajectory and to stabilize its motion along it. A new change of variable is suggested that reduces the problem of stabilizing robot's motion to that of stabilizing the zero solution in the form that admits feedback linearization. A control law stabilizing robot's motion along an arbitrary curvilinear target trajectory is synthesized. For a straight target path, the closed-loop system is shown to be asymptotically stable for any initial conditions except for the case where the initial direction of motion is perpendicular to the target path. © Pleiades Publishing, Ltd., 2012.

Consideration was given to the model containing coupled subsystems (MCCS). With no connection between the subsystems, the MCCS falls down into independent subsystems, that is, systems of autonomous ordinary differential equations. MCCS with cycles in the subsystems were examined. For the autonomous MCCS, conditions were established for cycles and their stability, and a cycle stabilization by the control explicitly independent of time was proposed. For the periodic MCCS, generation of isolated periodic solutions was proved, and the problem of their stability and stabilization was solved. © 2015, Pleiades Publishing, Ltd.

Consideration was given to the model containing coupled subsystems (MCCS). In the absence of coupling, MCCS falls down into independent subsystems represented by autonomous ordinary differential equations (ODE). In the structure of the entire system its subsystems make up hierarchical levels. The autonomous MCCS was studied. The “cycle or family of periodic motions” alternative was shown to be always realized by an individual system in a nondegenerate situation. For the main mode of oscillations, a scenario was given for bifurcation of the family of all families of periodic solutions arising with generation of the MCCS cycles. Consideration was given to stability of cycles, and the problem of their stabilization was solved. © 2015, Pleiades Publishing, Ltd.

A new approach to the controllability and observability properties, based on controllability and observability matrices links, is considered. The approach is based on matrices A, Am integrals expansion Lemma and properties of the matrices function convolution in complex plane. Coefficients of characteristic equations and Faddeev's matrices in the resolvent expansion of the system dynamic matrix play a dominant role in matrices integrals expansion forming. The gramians expansion on dynamic system matrix spectrum provide a new notion for the solutions of the Lyapunov and Sylvester equations. The results are illustrated by the example for two-zones furnace control. © 2010 IFAC.
