Applications of recurrence quantified analysis to study the dynamics of chaotic chemical reaction

Recurrence plot is a quite easy tool to be used in time-series analysis, in particular for measuring unstable periodic orbits embedded in a chaotic dynamical system. Recurrence quantified analysis (RQA) is an advanced tool that allows the study of intrinsic complexity of a dynamical system with a set of few parameters. We use RQA for measuring chaotic transitions of Nicotinamide adenine dinucleotide (NADH) chemical reaction and to determine numerically its characteristic parameters such as: correlation integral, information entropy, Maximal Lyapunov's exponent, etc. For this work we have developed command sets with a better performance than TISEAN package.
