PACS. 05.45+b – Theory and models of chaotic systems. PACS. 47.20Ky – Nonlinearity (including bifurcation theory). Abstract. – We consider the behavior of rings of unidirectionally coupled chaotic systems. When the number of oscillators in the ring is below a certain critical number the behavior of the ring is chaotic synchronized, while above this… (More)

Spatiotemporal stochastic forcing of an ensemble system consisting of chaotic Lorenz cells diffusively coupled is analyzed. The nontrivial effects of time and length correlations on the ensemble mean error and spread are studied and the implications to new trends in weather forecast methodologies are discussed. A maximum for the forecast scores is observed… (More)

An integrated system named METEOMOHID, developed by MeteoGalicia in the first stage of the Prestige accident in November 2002 was used successfully in an operational form to support decision making and assist in recovering tasks. Afterwards, METEOMOHID has been enhanced with the aim of developing an operational oceanography system to be used in the NW of… (More)

The effect of time-correlated zero-mean Gaussian noise on chaotic synchronization is analyzed experimentally in small-size arrays of Chua's circuits. Depending on the correlation time, an improvement of the synchronization is found for different values of the noise amplitude and coupling diffusion between circuits. Recently there has been considerable… (More)

—Chaotic synchronization is studied in experiments performed on dynamic arrays of Chua's circuits that are connected by using a recently introduced driving method especially suited for the design of such arrays. Namely, the driven circuit has the same number of energy storage elements as the driving circuit. The experimental results, which are supported by… (More)

The interaction of two chaotic rotating waves of the type recently reported by Matías et al. [Europhys. Lett. 37 (1997) 379] is studied experimentally with arrays of non-linear electronic circuits arranged in ring geometries. Unidirectional coupling is assumed for the cell-to-cell coupling within the same ring, but between rings, cells are coupled… (More)

Chaotic synchronization has been observed experimentally and numerically in arrays of Chua's circuits, arranged in both linear and ring geometries, that are coupled by using the method recently introduced by Güémez and Matías ͓Phys. Rev. E 52, R2145 ͑1995͔͒. For open linear geometries, the chaotic cells are seen to synchronize consecutively as a… (More)

517 Since by Lemma 2.1 the system states n(1) and N g (1) are nonneg-ative, we can write (37) as _ W (X) 0 minfbNa + c; d; 2eg 1 Na 2(1 0) Thus, we have the linear differential inequality _ W (t) 0 BLOCKINW(t) (39) where := minfbNa + c; d; 2eg > 0: (40) By a comparison theorem given in [15, p. 2] or [16, p. 3] we conclude that W in (39) satisfies W (X) W (X… (More)

The motion of contracting and expanding bubbles in an incompressible chaotic flow is analyzed in terms of the finite-time Lyapunov exponents. The viscous forces acting on the bubble surface depend not only on the relative acceleration but also on the time dependence of the bubble volume, which is modeled by the Rayleigh-Plesset equation. The effect of… (More)
