This paper proposes a novel application of a chaos particle swarm optimization (PSO) algorithm for tracking a maximum power point (MPP) of a solar photovoltaic (PV) panel under varying atmospheric conditions. Solar PV cells have a nonlinear V-I characteristic with a distinct MPP which depends on environmental factors such as temperature and irradiation. In order to continuously harvest maximum ...

We show that interactions of inherently chaotic oscillators can lead to coexistence regular oscillatory regimes and oscillations in the rings coupled provided level interaction between exceeds a threshold value. The transformation initially dynamics into number is shown result from suppression chaos by separation certain oscillation periods continuous spectra, which are characteristic oscillati...

We review recent progress relating to the extreme value statistics of characteristic polynomials random matrices associated with classical compact groups, and Riemann zeta-function other $L$-functions, in context general theory logarithmically-correlated Gaussian fields. In particular, we focus on developments related conjectures Fyodorov \& Keating concerning statistics, moments moments, conne...

Chaos is a nonlinear behavior that shows chaotic and irregular responses to internal and external stimuli in dynamic systems. This behavior usually appears in systems that are highly sensitive to initial condition. In these systems, stabilization is a highly considerable tool for eliminating aberrant behaviors. In this paper, the problem of stabilization and tracking the chaos are investigated....

The autocorrelation function of pattern fluctuation is used to study soft-mode turbulence (SMT), a spatiotemporal chaos observed in homeotropic nematics. We show that relaxation near the electroconvection threshold deviates from the exponential. To describe this relaxation, we propose a compressed exponential appearing in dynamics of glass-forming liquids. Our findings suggest that coherent mot...

The nonlinear dynamics of Chua’s circuit and its applications to communications is studied. Chaos is realized, and is investigated by calculating the Lyapunov exponent for the system. A three dimensional phase portrait for the characteristic double scroll is reconstructed from the two dimensional image, from which the correlation dimension is calculated. This experiment was done by designing Ch...

We study the avoided crossings in the dynamics of quantum controlled excitations for an interacting two-boson system in an optical lattice. Specifically, we perform numerical simulations of quantum control in this system where driving pulses connect the undriven stationary states in a manner characteristic of Stimulated Raman Adiabatic Passage (STIRAP). We demonstrate that the dynamics of such ...

We demonstrate experimental chaos synchronization between two chaotic semiconductor lasers subjected to polarization-rotated optical feedback and unidirectional injection. This system allows high-quality synchronization to be obtained between dissimilar lasers in a wide range of chaotic operating regimes. Another feature of this system is its operation at high characteristic frequencies, taking...

The cemented filling body is taken as the object of this study, whose nonlinear dynamic characteristics of damage and instability are researched by virtue of acoustic emission (AE) under uniaxial cyclic loading and unloading test. The results show that there exists similarity in variation trend between correlation dimension and maximum Lyapunov exponent during each loading stage, which also ver...
