Nonseparation Method-Based Finite/Fixed-Time Synchronization of Fully Complex-Valued Discontinuous Neural Networks

IEEE Transactions on Cybernetics, 2020
This article mainly focuses on the problem of synchronization in finite and fixed time for fully complex-variable delayed neural networks involving discontinuous activations and time-varying delays without dividing the original complex-variable neural ...

Synchronous electric time service

Electrical Engineering, 1932
PREVIOUS to 1916 no commercial a-c. system was regulated with sufficient accuracy of speed to enable its use for indicating time. Two devices then were developed making commercial a-c. time service possible. The first of these was a selfstarting synchronous motor which utilized residual magnetism to enable the rotor to start and run at synchronous ...

Proper time synchronization

Foundations of Physics, 1991
A clock-transport method of synchronization employing proper time is described that yields in any given inertial system the same result as slow transport, but that imposes no limit on transport proper speed. It is argued that because the method involves only the empirically validated kinematic invariant proper time, on which all observers must agree ...

Finite-Time Synchronization for Delayed Complex Dynamical Networks With Synchronizing or Desynchronizing Impulses

IEEE Transactions on Neural Networks and Learning Systems, 2020
In this article, the finite-time synchronization problem of delayed complex dynamical networks (CDNs) with impulses is studied, where two types of impulses, namely, synchronizing impulses and desynchronizing impulses, are fully considered, respectively ...

Finite-Time Synchronization and ${\mathcal{H}}_{\infty}$ Synchronization of Multiweighted Complex Networks With Adaptive State Couplings

IEEE Transactions on Cybernetics, 2020
In this paper, two kinds of multiweighted and adaptive state coupled complex networks (CNs) with or without coupling delays are presented. First, we develop the appropriate state feedback controller and adaptive law for the sake of guaranteeing that the ...

Synchronic Times

2017
The seventh chapter retraces the encounter of the French philosopher Daniel Bensaid and the work of Walter Benjamin, that reveals a resonance between two crucial turns of the twentieth century—1940 and 1990—through a vision of history based on the idea of remembrance.

Timing and Synchronization

1995
The WIS network will consist of digital access and nodal switches interconnected by time division multiplexed and bulk encrypted links. Timing and Synchronization (T & S) functions are therefore of vital importance for WIS. The synchronization concept must define the technical criteria to distribute and maintain permitted timing relationships at the ...

Novel Finite-Time Synchronization Criteria for Inertial Neural Networks With Time Delays via Integral Inequality Method

IEEE Transactions on Neural Networks and Learning Systems, 2019
In this paper, we are concerned with the finite-time synchronization of a class of inertial neural networks with time delays. Without applying some finite-time stability theorems, which are widely applied to studying the finite-time synchronization for ...

Fixed Time Synchronization Control for Bilateral Teleoperation Mobile Manipulator With Nonholonomic Constraint and Time Delay

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2020
In this brief, the fixed time synchronization control is investigated for nonholonomic mobile manipulator teleoperation system. The mobile manipulator is divided into two subsystems for analysis, which are nonholonomic mobile platform and holonomic ...
