A simple current-reversible chaotic jerk circuit is proposed and particularly demonstrates the use of inherently tanh(x) nonlinearity of a single opamp for a chaotic jerk circuit. No additionally nonlinear devices are required. Bifurcation is electronically tunable through a current source in a reversible direction. The largest Lyapunov exponent of either direction forms mirror images, whereas ...

The kinematics of motor task performance affect brain activity. However, few functional magnetic resonance imaging (fMRI) motor studies have accounted for on-line kinematics because there are currently few MRI-compatible devices to record motor performance. We built a device based on Micro-Electro-Mechanical System (MEMS) gyroscopes that measures the angular velocity of one segment of each of t...

contact dermatitis is an inflammatory reaction of the skin and mucosa to either external or internal factors. it can be divided to two forms of irritant contact dermatitis and allergic contact dermatitis. nickel is one of the most common materials that causes allergic contact dermatitis and is widely used in orthodontic appliances. the inflammatory reaction to this metal in orthodontics is usua...

Abstract To make a trajectory enough to track unmanned skid-steering vehicles, planning method is proposed in this paper. The planner consists of velocity planning, curvature and path planning. Subject the constraints jerk acceleration, has five possibilities. Then taking into account, three And according sequence sequence, information can be obtained by kinematic model. verify presented method...

In the present study, we investigate a control mechanism that dampens hand vibrations. Here, we propose a control method with two components to suppress hand vibrations. The first is a passive suppression method that lowers the joint stiffness to passively dampen the hand vibrations. The second is an active suppression method that adjusts an equilibrium point based on skyhook control to activel...
