Dimensional Characteristics of Diffusion Chaos

open access: yesМоделирование и анализ информационных систем, 2013
The phenomenon of multimode diffusion chaos is considered. For a number of examples it is shown that the Lyapunov dimension of the attractor of a distributed dynamical system increases as the diffusion coefficient tends to 0.

Lyapunov functions for linear nonautonomous dynamical equations on time scales [PDF]

open access: yes, 2006
The existence of a Lyapunov function is established following a method of Yoshizawa for the uniform exponential asymptotic stability of the zero solution of a nonautonomous linear dynamical equation on a time scale with uniformly bounded ...

THE INFLUENCE OF THE STIFFNESS COEFFICIENT OF THE HYDRAULIC LIQUID ON THE DYNAMICAL BEHAVIOUR OF THE SYSTEM “HYDRAULIC CYLINDER – LOAD” [PDF]

open access: yes, 2016
In this paper we suggest a way how to determine the stiffness coefficient of the hydraulic liquid in a hydraulic cylinder under load and we also show its influence on the dynamical properties and behavior of the system “hydraulic cylinder– load”.In this ...

Exponential attractor for Kirchhoff model with time delay and thermal effect

open access: yesResults in Applied Mathematics, 2023
The Kirchhoff model is derived from the vibration problem of stretchable strings. In this paper, we focus on the long-time dynamics of the Kirchhoff model with time delay and thermal effect.

Oscillation of delay dynamic equations with oscillating coefficients [PDF]

open access: yesDifferential Equations & Applications, 2013
In this paper, we study the following delay dynamic equation x Δ (t)+p(t)x(τ(t)) = 0f ort ∈ (t0,∞)T, where t0 ∈ T ,s upT = ∞, p ∈ Crd((t0,∞)T,R) alternates in sign infinitely many times and τ ∈ Crd((t0,∞)T,T) is a strictly increasing unbounded function satisfying τ(t) t for all t ∈ (t0,∞)T. Our results extend recent results for arbitrary time scales.

A dynamic model for the Lagrangian stochastic dispersion coefficient [PDF]

open access: yesPhysics of Fluids, 2013
A stochastic sub-grid model is often used to accurately represent particle dispersion in turbulent flows using large eddy simulations. Models of this type have a free parameter, the dispersion coefficient, which is not universal and is strongly grid-dependent.
