Academic Editor: Giorgio Kaniadakis Received: 22 December 2014 / Accepted: 2 March 2015 / Published: 6 March 2015 Abstract: In this paper we consider dynamics of non-stationary processes that follow the MaxEnt principle. We derive a set of equations describing dynamics of a system for Shannon and Tsallis entropies. Systems with discrete probability distribution are considered under mass conservation and energy conservation constraints. The existence and uniqueness of solution are established and asymptotic stability of the equilibrium is proved. Equations are derived based on the speed-gradient principle originated in control theory.

Introduction The notion of entropy is widely used in modern statistical physics, thermodynamics, information theory, engineering, etc. In 1948, Claude Shannon [1] introduced the entropy of a probability distribution P (X) as X S(X) = − P (xi) log P (xi); (1) i Entropy 2015, 17 1091 where X is a discrete random variable with possible values fx1; :::; xng. -

Control of Chaos: Methods and Applications
Automation and Remote Control, Vol. 64, No. 5, 2003, pp. 673{713. Translated from Avtomatika i Telemekhanika, No. 5, 2003, pp. 3{45. Original Russian Text Copyright c 2003 by Andrievskii, Fradkov. REVIEWS Control of Chaos: Methods and Applications. I. Methods1 B. R. Andrievskii and A. L. Fradkov Institute of Mechanical Engineering Problems, Russian Academy of Sciences, St. Petersburg, Russia Received October 15, 2002 Abstract|The problems and methods of control of chaos, which in the last decade was the subject of intensive studies, were reviewed. The three historically earliest and most actively developing directions of research such as the open-loop control based on periodic system ex- citation, the method of Poincar´e map linearization (OGY method), and the method of time- delayed feedback (Pyragas method) were discussed in detail. The basic results obtained within the framework of the traditional linear, nonlinear, and adaptive control, as well as the neural network systems and fuzzy systems were presented. The open problems concerned mostly with support of the methods were formulated. The second part of the review will be devoted to the most interesting applications. 1. INTRODUCTION The term control of chaos is used mostly to denote the area of studies lying at the interfaces between the control theory and the theory of dynamic systems studying the methods of control of deterministic systems with nonregular, chaotic behavior. In the ancient mythology and philosophy, the word \χαωσ" (chaos) meant the disordered state of unformed matter supposed to have existed before the ordered universe. The combination \control of chaos" assumes a paradoxical sense arousing additional interest in the subject. -
Math Morphing Proximate and Evolutionary Mechanisms

Nesse and George C. Williams summarize its relevance to medicine: All biological traits need two kinds of explanation: proximate and evolutionary. The proximate explanation for a disease describes what is wrong in the bodily mechanism of individuals affected Curriculum Unit 09.05.09 1 of 27 by it. An evolutionary explanation is completely different. Instead of explaining why people are different, it explains why we are all the same in ways that leave us vulnerable to disease. Why do we all have wisdom teeth, an appendix, and cells that if triggered can rampantly multiply out of control? [1] A fractal is generally "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity. The term was coined by Beno?t Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion. http://www.kwsi.com/ynhti2009/image01.html A fractal often has the following features: 1. It has a fine structure at arbitrarily small scales. -

In the early 1990s, the tem without equilibrium in this paper. On the basis of the linear synchronization of chaotic systems was achieved by Pecora mathematical model of the two-wheeled self-balancing robot, a and Carroll[14;15], which was a trailblazing result, and the novel chaotic system which has no equilibrium is proposed. The basic dynamical properties of this new system are studied via result promoted the development of chaos control and chaos [16;17] Lyapunov exponents and Poincare´ map. To further demonstrate synchronization . In recent years, different chaos control the physical realizability of the presented novel chaotic system, a and chaos synchronization strategies have been developed chaotic circuit is designed. By using fractional-order operators, for chaotic systems. The sliding mode control method was a controller is designed based on the state-feedback method. applied to chaos control[18;19] and chaos synchronization[20]. According to the Gronwall inequality, Laplace transform and Mittag-Leffler function, a new control scheme is explored for the In [21], the feedback control method and the adaptive control whole closed-loop system. Under the developed control scheme, method were used to realize chaos control for the energy the state variables of the closed-loop system are controlled to resource chaotic system. The chaos control problems were stabilize them to zero. Finally, the numerical simulation results investigated for Lorenz system, Chen system and Lu¨ system of the chaotic system with equilibrium and without equilibrium based on backstepping design method in [22]. -
