Effect of Circuit Breaker Shunt Resistance on Chaotic Ferroresonance in Voltage Transformer

open access: yesAdvances in Electrical and Computer Engineering, 2010
Ferroresonance or nonlinear resonance is a complex electrical phenomenon, which may cause over voltages and over currents in the electrical power system which endangers the system reliability and continuous safe operating. This paper studies the effect

On systems of maximal quantum chaos [PDF]

open access: yes, 2021
A remarkable feature of chaos in many-body quantum systems is the existence of a bound on the quantum Lyapunov exponent. An important question is to understand what is special about maximally chaotic systems which saturate this bound. Here we provide further evidence for the `hydrodynamic' origin of chaos in such systems, and discuss hallmarks of ...

Deterministic chaos in an ytterbium-doped mode-locked fiber laser

open access: yes, 2018
We experimentally study the nonlinear dynamics of a femtosecond ytterbium doped mode-locked fiber laser. With the laser operating in the pulsed regime a route to chaos is presented, starting from stable mode-locking, period two, period four, chaos and ...

Attenuation of Line Spectra and Vibration Based on a Chaotification Method and Global Analysis

open access: yesShock and Vibration, 2022
The chaotification method can be used to weaken the line spectra component of the ship's radiated noise. The main obstacle that plagues the engineering realization of this innovative concept is how to realize the small-amplitude chaotic motion of the ...
