Many studies have been shown and focused that variation of the quantity of vasoconstriction and blood pressure will cause the nonlinear chaotic behaviors in the heart blood vessel system and then induce the cardiovascular effect. Due to this kind of non-periodic motion is random and difficult to control, it is important to analyze and understand the status of dynamic system under different parametric...
An aero elastic system combines several complex theories of physics. These principles will cause instability situations or be interacted each other. If this behavior occurs, it will result in the fatigue problems or structural damages on the wings of aircrafts. In order to avoid these conditions to occur, this paper studies the nonlinear dynamic behaviors of aero elastic system under specific operating...
The behavior of a novel frequency divider circuit using negative differential resistance (NDR) circuit is studied. This NDR circuit is made of resistors (R) and bipolar-junction-transistor (BJT) devices. It can show the NDR characteristic in its combined current-voltage curve by suitably arranging the resistances. We call this NDR circuit as R-BJT-NDR circuit in this paper. A chaos circuit consisted...
This paper presents the design of a nonlinear rule based fuzzy logic controller for the nonlinear dynamic behavior of the probe tip of an atomic force microscope system (AFMs). At first, we use the bifurcation diagram to analysis the complex dynamic behavior of the atomic force microscope system. Next, the positive maximum Lyapunov exponent is obtained to identify that the chaotic motion do exist...
