Nonuniform gyrotropic oscillation of skyrmion in a nanodisk
It was predicted that magnetic skyrmions have potential application in the spin nano-oscillators. The oscillation frequency is a key parameter. In this paper, we study the skyrmion relaxation in a FeGe nanodisk and find that the oscillation frequency ...

A neural network approach for composite fractional relaxation oscillation equations in complex dynamical systems [PDF]
The relaxation oscillator is a system that operates on the tendency of physical processes to return to equilibrium after being disturbed. Its governing equation, the relaxation–oscillation equation, plays a central role in diverse fields such as physics,

Two-stroke relaxation oscillators [PDF]
Abstract Two-stroke relaxation oscillations consist of two distinct phases per cycle—one slow and one fast—which distinguishes them from the well-known van der Pol-type ‘four-stroke’ relaxation oscillations. This type of oscillation can be found in singular perturbation problems in

Stochastic and chaotic relaxation oscillations [PDF]
For relaxation oscillators stochastic and chaotic dynamics are investigated. The effect of random perturbations upon the period is computed. For an extended system with additional state variables chaotic behavior can be expected. As an example, the Van der Pol oscillator is changed into a third-order system admitting period doubling and chaos in a ...

Influence of oscillation strain on the dynamic mechanical relaxation of a La-based metallic glass [PDF]
Dynamic mechanical relaxation processes, particularly secondary relaxation processes, are closely related to the mechanical and physical properties of metallic glasses.

During polymer melt extrusion from a circular nozzle, the extrudate at low flow rate shows a stable linear shape with smooth surface but the extrudate at higher flow rate shows unstable shapes with spiral, rosary, or zig-zag structures.
