Recurrence quantification based Liapunov exponents for monitoring divergence in experimental data

Although the use of positive Liapunov exponents has been emphasized in the context of confirmation of chaotic dynamics, their original conception concerned system stability as a qualitative feature. Using a recurrence-based algorithm, data from experimental reactions are presented for exponent use in this context. Emphasis is placed on the utility for on-line, nonstationary, noisy systems.
