Stochastic patch structure Nicholson’s blowflies system with mixed delays

open access: yesAdvances in Difference Equations, 2020
This paper is devoted to studying a stochastic patch structure Nicholson’s blowflies system with mixed delays which is a new model for the generalization of classic Nicholson’s blowflies system.

Attractor and Boundedness of Switched Stochastic Cohen-Grossberg Neural Networks

open access: yesDiscrete Dynamics in Nature and Society, 2016
We address the problem of stochastic attractor and boundedness of a class of switched Cohen-Grossberg neural networks (CGNN) with discrete and infinitely distributed delays.

Ultimate Boundedness of the Systems Governed by Stochastic Differential Equations [PDF]

open access: yesNagoya Mathematical Journal, 1972
The stability of the systems given by ordinary differential equations or functional-differential equations has been studied by many mathematicians. The most powerful tool in this field seems to be the Liapunov’s second method (see, for example [6]).

New Nonlinear Takagi–Sugeno Vehicle Model for State and Road Curvature Estimation via a Nonlinear PMI Observer

open access: yesJournal of Intelligent Systems, 2014
The present article deals with an observer design for nonlinear vehicle lateral dynamics. The contributions of the article concern the nonconsideration of any force model and the consideration that the longitudinal velocity is time varying, which is more

Global Uniform Ultimate Boundedness of Semi-Passive Systems Interconnected over Directed Graphs [PDF]

open access: yes, 2023
We analyse the solutions of networked heterogeneous nonlinear systems. We assume that the closed-loop interconnected systems form a network with an underlying connected directed graph that contains a directed spanning tree.

The control of drilling vibrations: A coupled PDE-ODE modeling approach

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2016
The main purpose of this contribution is the control of both torsional and axial vibrations occurring along a rotary oilwell drilling system. The model considered consists of a wave equation coupled to an ordinary differential equation (ODE) through a ...

A New Robust Tracking Control Design for Turbofan Engines: H∞/Leitmann Approach

open access: yesApplied Sciences, 2017
In this paper, a H ∞ /Leitmann approach to the robust tracking control design is presented for an uncertain dynamic system. This new method is developed in the following two steps. Firstly, a tracking dynamic system with simultaneous consideration

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Uniform ultimate boundedness and periodicity in functional-differential equations

open access: yesTohoku Mathematical Journal, 1990
We consider the existence of periodic solutions of functional differential equations with infinite delay, (1) \(x'=f(t,x_ t)\). Let \((X,\| \cdot \|)\) be the space of bounded continuous functions \(\phi\) : (-\(\infty,0]\to R^ n\) with the supremum norm and let G denote the set of continuous nonincreasing functions g: (-\(\infty,0]\to [1,\infty ...
