Van der Pol Equation with a Large Feedback Delay

open access: yesMathematics, 2023
The well-known Van der Pol equation with delayed feedback is considered. It is assumed that the delay factor is large enough. In the study of the dynamics, the critical cases in the problem of the stability of the zero equilibrium state are identified ...

Quasinormal Forms for Chains of Coupled Logistic Equations with Delay

open access: yesMathematics, 2022
In this paper, chains of coupled logistic equations with delay are considered, and the local dynamics of these chains is investigated. A basic assumption is that the number of elements in the chain is large enough.

Asymptotics of Regular and Irregular Solutions in Chains of Coupled van der Pol Equations

open access: yesMathematics, 2023
Chains of coupled van der Pol equations are considered. The main assumption that motivates the use of special asymptotic methods is that the number of elements in the chain is sufficiently large.

On the 3D consistency of a Grassmann extended lattice Boussinesq system

open access: yesNuclear Physics B, 2020
In this paper, we formulate a “Grassmann extension” scheme for constructing noncommutative (Grassmann) extensions of Yang-Baxter maps together with their associated systems of PΔEs, based on the ideas presented in [15].

Infinite Turing Bifurcations in Chains of Van der Pol Systems

open access: yesMathematics, 2022
A chain of coupled systems of Van der Pol equations is considered. We study the local dynamics of this chain in the vicinity of the zero equilibrium state.

Neural systems integration [PDF]

open access: yesNeurocomputing, 2004
A need is identified to build models of the central nervous system that are semi-complete, applied within multiple contexts to multiple tasks, using methodologies that span multiple levels of abstraction. The issues and constraints in building such models are discussed with respect to completeness, validation, cost, scalability and robustness.

Integration of energy systems [PDF]

open access: yesMRS Bulletin, 2021
This article in MRS Bulletin and the framework set out in the introductory article articulate a scenario of renewable electrons and electrification of end use appliances and industrial processes as a plausible paradigm to realize a carbon-free energy economy.

An Optimization-Based Reconfigurable Design for a 6-Bit 11-MHz Parallel Pipeline ADC with Double-Sampling S&H

open access: yesInternational Journal of Reconfigurable Computing, 2012
This paper presents a 6 bit, 11 MS/s time-interleaved pipeline A/D converter design. The specification process, from block level to elementary circuits, is gradually covered to draw a design methodology.
