Online detection of hydrodynamics of gas-solid fluidized bed was characterized using pressure fluctuations by cross recurrence plot (CRP) and cross recurrence quantification analysis (CRQA). Experiments were conducted in a lab scale fluidized bed of various particle sizes 150 μm, 280 μm and 490 μm at different gas velocities. Firstly, pattern changes of cross recurrence plot were discussed and ...

In this paper the Generalized Recurrence Plot and Generalized Recurrence Quantification Analysis are exploited to investigate spatially distributed systems characterized by a Hopf bifurcation. Specifically, the Complex GinzburgLandau equation is chosen as a prototypical example. Steady state spatial pattern evolution is studied by computing the recurrence quantification parameters Determinism (...

Recurrence plots were introduced to quantify the recurrence properties of chaotic dynamics. Hereafter, the recurrence quantification analysis was introduced to transform graphical interpretations into statistical analysis. In this spirit, a new definition for the Shannon entropy was recently introduced in order to have a measure correlated with the largest Lyapunov exponent. Recurrence plots an...
