Kevin Lin 1 Introduction is a= 3 which in the case of the logistic map is not even large enough to be chaotic, though the condition is irrespective of the exact map. They are predominantly used to qualitatively study the chaotic dynamics of spatially extended systems. CYCLING CHAOS IN ONE-DIMENSIONAL COUPLED ITERATED MAPS ANTONIO PALACIOS Department of Mathematics, San Diego State University, San Diego, CA 92182-7720, USA Received July 11, 2001; Revised August 3, 2001 Cycling behavior involving steady-states and periodic solutions is known to be a generic feature of continuous dynamical systems with symmetry. Model Description Chaotic maps are generally used for several approaches to investigate chaotic phenomena on coupled chaotic sys-tems. We will only consider three examples of the map f: the linear map (Section 3), the logistic map (Section 4) used by Kaneko, and the circle map (Section 5).

We have set out a new approach, the MAPS control paradigm, which exploits the dynamical characteristics of chaotic maps in the context of coupled map lattices to effect control over many timescales. Department of Physics, Kagoshima University, Kagoshima 890. Introduction Coupled chaotic systems generate various kinds of complex higher-dimensional phenomena such as spatio-temporal chaotic phenomena, clustering phenomena and so on. Coupled chaotic map lattice. Introduction Hashing is a basic technique for information security, and usually applied to data integrity protection[1], message authentication[2] and digital signatures[3]. After the coherence loses stability the whole system is attracted to a …map is also discussed based on different coupled networks. By cross-coupling two logistic maps a novel method is proposed for JPEG steganography.

The results of this paper highlight the advantages of random connectivity for synchronization of coupled chaotic dynamical systems. 2. coupled neurons The main goal here is to characterize the dif- ferent regimes of synchronization observed in the model system as a function of the strength of the inhibitory coupling and the number of coupled neu- rons.

A coupled map lattice (CML) is a dynamical system that models the behavior of non-linear systems (especially partial differential equations). Design a New Image Encryption using Fuzzy Integral Permutation with Coupled Chaotic Maps 29 In recent years, algebraic operations such as the addition operation, based on the DNA sequence have been proposed by researchers [4, 23]. The scaling hypothesis for the coupled chaotic map lattices (CML) is formulated. A conditional mean-field approach to strongly chaotic coupled map lattices is presented. N.

D. attractors and the sensitivity of chaotic processes of the logistic map Mar 2, 2012 A chaotic map of the form xn+1 = F(xn) does also have the Markov property, and . One of the most studied systems may be the coupled map lattice proposed by Kaneko [1]. We have the equipment and staff to handle your house and office cleaning needs.

In novel algorithm based on mixture of chaotic maps or coupled map, a typical coupled map was mixed with a one-dimensional chaotic map and used for high degree security image encryption while its speed is acceptable, and also it has large key space than the NCA map. The local environment of a site is modelled in terms of an effective number of independent neighbours, while keeping the Perron-Frobenius operator to account for the action of the local map. Dr. The paper investigates the conditions for full and partial synchronization in systems of coupled chaotic maps that include the presence of a major element, that is, an element that interacts with all the other elements of the system. 11].

Let us consider aCOUPLED MAP LATTICES AS MUSICAL INSTRUMENTS 3 CMLs were utilized by Kunihiko Kaneko [Kan93] to model spatiotemporal chaos with discrete-time, discrete-space, and continuous-state dynamics. In those cases, the collective behavior consists in statistical cycling of the mean field (or the probabil- ity density) among chaotic bands of the local one- hump maps [2,3. At the same time, the transition from a non-chaotic to chaotic in coupled networks is exhibited, although the parameters in non-chaotic regions before they are coupled together. network traffic modeling, (ii) can be combined with . SimulationPeriodic collective states have been observed in higher di- mensional lattices of locally chaotic coupled maps. A. Port Manteaux churns out silly new words when you feed it an idea or two. Weak Synchronization of Chaotic Coupled Map Lattices F. in the proposed coupled systems. Chaotic Coupled Map Lattices Author. Scaling properties of the CML in the regime of extensive chaos observed numerically before is justified analytically. For example, 11 + 10 = 01 or G + T=A. It is known that relaxation to pushed fronts is fast, exponential in time, whereas relaxation to pulled front is slow, with algebraic rates. pled chaotic circuits and asymmetrically coupled chaotic maps. Especially, the logistic map and the other types of chaotic maps such as a cut map, a circle map, a tent map, a cubic map are well known and popular. Introduction. We could demonstrate that the use of coupled chaotic maps to encryption is a secure system and due to the high speed, the proposed cryptosystem is suitable for application in real-time communication systems like video encryption.

In this paper, we use discrete cross-coupled chaotic maps for specifying the location of the different parts of the secret data in the image. It focusses on the time evolution of the one-body probability distribution function p(X) of instantaneous site values. Chaotic maps entail high complexity in the used algorithm for embedding secret data in a medium.
