Synchronization Dynamics in the Presence of Coupling Delays and Phase Shifts
(American Physical Society, 2014-05)
In systems of coupled oscillators, the effects of complex signaling can be captured by time delays and phase shifts. Here, we show how time delays and phase shifts lead to different oscillator dynamics and how synchronization ...
Chaotic phase synchronization and desynchronization in an oscillator network for object selection
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Object selection refers to the mechanism of extracting objects of interest while ignoring other objects and background in a given visual scene. It is a fundamental issue for many computer vision and image analysis techniques ...
Network of phase-locking oscillators and a possible model for neural synchronization
(ELSEVIER SCIENCE BV, 2011)
In order to model the synchronization of brain signals, a three-node fully-connected network is presented. The nodes are considered to be voltage control oscillator neurons (VCON) allowing to conjecture about how the whole ...
Evaluation of Quadrature Signal Generation Methods with Reduced Computational Resources for Grid Synchronization of Single-Phase Power Converters through Phase-Locked Loops
Low-cost single-phase grid connected converters require synchronization with the grid voltage to obtain a better response and protection under diverse conditions, such as frequency perturbations and distortion. Phase-locked ...
Geometrical properties of coupled oscillators at synchronization
(Elsevier B.V., 2011-11-01)
We study the synchronization of N nearest neighbors coupled oscillators in a ring. We derive an analytic form for the phase difference among neighboring oscillators which shows the dependency on the periodic boundary ...

Reachability of the synchronous state in a mutually connected PLL network
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009)
Second-order phase locked loops (PLLs) are devices that are able to provide synchronization between the nodes in a network even under severe quality restrictions in the signal propagation. Consequently, they are widely ...
Analytical calculation of the transition to complete phase synchronization in coupled oscillators
(SPRINGER, 2008)
Here we present a system of coupled phase oscillators with nearest neighbors coupling, which we study for different boundary conditions. We concentrate at the transition to the total synchronization. We are able to develop ...
