Buckling and postbuckling of axially-loaded CNT-reinforced composite cylindrical shell surrounded by an elastic medium in thermal environment

Vietnam Journal of Mechanics, 2019
The natural frequencies or related resonant frequencies have been widely used for crack detection in structures by the vibration-based technique. However, antiresonant frequencies, the zeros of frequency response function, are less involved to use for ...

Solitary waves in the Nonlinear Dirac Equation [PDF]

, 2017
In the present work, we consider the existence, stability, and dynamics of solitary waves in the nonlinear Dirac equation. We start by introducing the Soler model of self-interacting spinors, and discuss its localized waveforms in one, two, and three ...

Stabilization and Analytic Approximate Solutions of an Optimal Control Problem

Open Physics, 2018
This paper analyses a dynamical system derived from a left-invariant, drift-free optimal control problem on the Lie group SO(3) × ℝ3 × ℝ3 in deep connection with the important role of the Lie groups in tackling the various problems occurring in physics ...

On Delay-independent Stability of a class of Nonlinear Positive Time-delay Systems

, 2013
We present a condition for delay-independent stability of a class of nonlinear positive systems. This result applies to systems that are not necessarily monotone and extends recent work on cooperative nonlinear systems.Comment: 9 ...

Nonlinear modes in finite-dimensional PT-symmetric systems

, 2012
By rearrangements of waveguide arrays with gain and losses one can simulate transformations among parity-time (PT-) symmetric systems not affecting their pure real linear spectra.

Pointwise convergence to a Maxwellian for a Broadwell model with a supersonic boundary

Networks and Heterogeneous Media, 2007
In this paper, we consider an initial-boundary value problem for the Broadwell model with a supersonic physical boundary. By using the Green’s function established in [6] and weighted energy estimates, we show that the solution converges pointwise to the

Stability of subdivision schemes [PDF]

, 1998
The stability of stationary interpolatory subdivision schemes for univariate data is investigated. If the subdivision scheme is linear, its stability follows from the convergence of the scheme, but for nonlinear subdivision schemes one needs stronger ...
