The ANVA comprises mass, linear spring, cubic nonlinear spring and actuator. The steady-state equation of the system is obtained by solving the governing differential equation by harmonic balance method. From the steady sta

They are widely used in biotechnological processes as fermentation and waste water treatment for the favorable mixing and mass transfer properties . In spite of practical and theoretical interest, only few works are devoted to the dynamical be

Period-doubling bifurcations and intermittent chaotic behavior were observed, depending on the value of the applied voltage. The dependencies of the fundamental frequency of low frequency current oscillations on the applied voltage were found to be sharply nonmonotonical in the samples of G

Recent experimental results can be interpreted using a drift-diffusion rate equation model which includes nonlinear electric field dependencies of the drift velocity and impurity capture and impact ionization rates. Under time-independent (dc) current bias, phase plane analysi
