Fixed-Time Multi-Switch Combined–Combined Synchronization of Fractional-Order Chaotic Systems with Uncertainties and External Disturbances

open access: yesFractal and Fractional, 2023
In this paper, the fixed-time multi-switch combination–combination synchronization (FTMSCCS) of fractional-order chaotic systems with uncertainties and external disturbances is studied.

Ovsynch synchronization and fixed-time insemination in goats

open access: yesTheriogenology, 2008
This study assessed the efficacy of an Ovsynch protocol (vs. the classical cronolone containing vaginal sponge+eCG treatment) to generate fixed-time insemination in goats during the breeding season. Each regimen was applied to 24 Boer goat does. Onset and duration of estrus were determined with an aproned male and follicular development was monitored ...

Fixed-Time Synchronization of Competitive Neural Networks With Multiple Time Scales [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2022
In this brief, we investigate the fixed-time synchronization of competitive neural networks with multiple time scales. These neural networks play an important role in visual processing, pattern recognition, neural computing, and so on. Our main contribution is the design of a novel synchronizing controller, which does not depend on the ratio between ...

Anticipatory synchronization with variable time delay and reset [PDF]

open access: yes, 2008
A method to synchronize two chaotic systems with anticipation or lag, coupled in the drive response mode, is proposed. The coupling involves variable delay with three time scales.

Robust fixed-time synchronization of discontinuous Cohen–Grossberg neural networks with mixed time delays

open access: yesNonlinear Analysis, 2019
This paper aims to investigate the fixed-time synchronization (i.e., synchronization in fixed-time sense) of Cohen–Grossberg drive-response neural networks with discontinuous neuron activations and mixed time delays (both time-varying discrete delay and ...

New finite-time synchronization analysis of a delayed memristive neurodynamic model

open access: yesAdvances in Difference Equations, 2020
This paper presents theoretical results on the finite-time synchronization of delayed memristive neural networks (MNNs). Compared with existing ones on finite-time synchronization of discontinuous NNs, we directly regard the MNNs as a switching system ...
