Toward Embedded System Resources Relaxation Based on the Event-Triggered Feedback Control Approach

open access: yesMathematics, 2022
The paper describes an event-triggered nonlinear feedback controller design. Event triggering is a real-time controller implementation technique which reduces embedded system utilization and relaxes task scheduling of the real-time system. In contrast to

Statistical mechanics of temporal association in neural networks with transmission delays [PDF]

open access: yes, 1991
We study the representation of static patterns and temporal sequences in neural networks with signal delays and a stochastic parallel dynamics. For a wide class of delay distributions, the asymptotic network behavior can be described by a generalized ...

Chaotic properties of planar elongational flow and planar shear flow: Lyapunov exponents, conjugate-pairing rule, and phase space contraction [PDF]

open access: yesPhysical Review E, 2006
The simulation of planar elongational flow in a nonequilibrium steady state for arbitrarily long times has recently been made possible, combining the SLLOD algorithm with periodic boundary conditions for the simulation box. We address the fundamental questions regarding the chaotic behavior of this type of flow, comparing its chaotic properties with ...

Dynamics of spinning test particles in Kerr spacetime [PDF]

open access: yes, 2002
We investigate the dynamics of relativistic spinning test particles in the spacetime of a rotating black hole using the Papapetrou equations. We use the method of Lyapunov exponents to determine whether the orbits exhibit sensitive dependence on initial ...

A multi-thread control algorithm with update delays based on event-triggered mechanism

open access: yesMeasurement + Control, 2023
In this paper, an event-triggered mechanism for a class of multi-thread control systems is designed by the relationship between the threshold line and the Lyapunov function and an algorithm is proposed with update delays considered. In order to solve the
