Simulation of vibrations of a continuously elastic supported rod with varying boundary conditions under the action of a movable

open access: yesMATEC Web of Conferences, 2018
To simulate the non-linear vibrations of a floating bridge of a continuous system on separate floating supports with additional limiting supports at the ends with a moving load solves the most complicated problem which is the problem of describing the ...

Observability of Linear Differential-algebraic Equations in the Class of Chebyshev Functions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
We consider linear time-varying systems of first order ordinary differential equations unresolved with respect to the derivative of the unknown function and identically degenerate in the domain.

On the birth of limit cycles for non-smooth dynamical systems [PDF]

open access: yes, 2014
The main objective of this work is to develop, via Brower degree theory and regularization theory, a variation of the classical averaging method for detecting limit cycles of certain piecewise continuous dynamical systems.

Slow invariant manifolds as curvature of the flow of dynamical systems [PDF]

open access: yes, 2014
Considering trajectory curves, integral of n-dimensional dynamical systems, within the framework of Differential Geometry as curves in Euclidean n-space, it will be established in this article that the curvature of the flow, i.e.

Pontryagin principle for a Mayer problem governed by a delay functional differential equation

open access: yes, 2016
We establish Pontryagin principles for a Mayer's optimal control problem governed by a functional differential equation. The control functions are piecewise continuous and the state functions are piecewise continuously differentiable.

A Framework for Worst-Case and Stochastic Safety Verification Using Barrier Certificates [PDF]

open access: yes, 2007
This paper presents a methodology for safety verification of continuous and hybrid systems in the worst-case and stochastic settings. In the worst-case setting, a function of state termed barrier certificate is used to certify that all trajectories of ...

Almost periodic solutions of retarded SICNNs with functional response on piecewise constant argument [PDF]

open access: yes, 2015
We consider a new model for shunting inhibitory cellular neural networks, retarded functional differential equations with piecewise constant argument. The existence and exponential stability of almost periodic solutions are investigated.
