The hyper-chaotic Mathieu-Van der Pol system is an important autonomous system model,
with four state variables and four Lyapunov exponents, three of which are positive. Also …

Non-linear energy harvesting system was project to enhance interaction to ambient vibration
that is wide band and low power which difficult the design for resonant solution. To improve …

In this paper we study the behavior of a semi-active suspension witch external vibrations.
The mathematical model is proposed coupled to a magneto rheological (MR) damper. The …

The majority of active control applications in vibrational dynamic systems are utilized to
minimize vibrations. The goal of this research, on the other hand, is to employ vibrations to …

The non-ideal vibration absorber system coupled to a nonlinear oscillator is proposed in the
paper. This system is demonstrated with a chaotic behavior and we present the control …
