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

Features of the determined chaos modes of dc voltage converters for wind and solar power stations

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2017
Relevance of the researches is defined by the necessity to increase the efficiency of converters for the needs of renewable energy. The strict and conflicting requirements are often imposed to the control algorithms of DC voltage converters used in solar

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 ...

A Flexible Subscription Model for Broadcasted Digital Contents [PDF]

open access: yes2007 International Conference on Computational Intelligence and Security (CIS 2007), 2007
In this paper, a novel method to estimate the intrinsic dimensionality of high-dimensional data set is proposed. Based on neighborhood information, our method calculates the non-negative locally linear reconstruction coefficients from its neighbors for each data point, and the numbers of those dominant positive reconstruction coefficients are regarded

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 ...

Using LabView environment for the demonstration of generator dynamic behavior

open access: yesE3S Web of Conferences, 2018
Under consideration is a virtual device (VD) in NI – LabVIEW environment for the demonstration of a generator dynamic behavior close to borders of its stability area. The generator is operating for the unlimited power system.

Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]

open access: yes, 2011
It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.
