On Asymptotic Completeness of Scattering in the Nonlinear Lamb System, II

open access: yes, 2012
We establish the asymptotic completeness in the nonlinear Lamb system for hyperbolic stationary states. For the proof we construct a trajectory of a reduced equation (which is a nonlinear nonautonomous ODE) converging to a hyperbolic stationary point ...

The numerical solution of the nonlinear hyperbolic-parabolic heat equation

open access: yesDiscrete and Continuous Models and Applied Computational Science
The article discusses a mathematical model and a finite-difference scheme for the heating process of an infinite plate. The disadvantages of using the classical parabolic heat equation for this case and the rationale for using the hyperbolic heat ...

Exact Solutions to the Sharma-Tasso-Olver Equation by Using Improved G′/G-Expansion Method

open access: yesJournal of Applied Mathematics, 2013
This paper is concerned with a double nonlinear dispersive equation: the Sharma-Tasso-Olver equation. We propose an improved G′/G-expansion method which is employed to investigate the solitary and periodic traveling waves of this equation.

De Giorgi's approach to hyperbolic Cauchy problems: the case of nonhomogeneous equations

open access: yes, 2017
In this paper we discuss an extension of some results obtained by E. Serra and P. Tilli, in [Serra&Tilli '12, Serra&Tilli '16], concerning an original conjecture by E.

A remark on asymptotic completeness for the critical nonlinear Klein-Gordon equation

open access: yes, 2005
We give a short proof of asymptotic completeness and global existence for the cubic Nonlinear Klein-Gordon equation in one dimension. Our approach to dealing with the long range behavior of the asymptotic solution is by reducing it, in hyperbolic ...

A Class of Nonlinear Hyperbolic Equations

open access: yesDemonstratio Mathematica, 1989
Let \(\Phi:[0,T] \times X \to(-\infty,\infty)\) be measurable with respect to the \(\sigma\)-algebra generated in \([0,T] \times X\) by products of Lebesgue sets in \([0,T]\) and Borel sets in \(X\); \(\Phi (t,\cdot)\) is lower semicontinuous and convex, and \(\partial \Phi\) denotes the subdifferential of \(\Phi (t,\cdot)\).

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Nonlinear Schrödinger equation on real hyperbolic spaces

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2009
We consider the Schrödinger equation with no radial assumption on real hyperbolic spaces \mathbb{H}^{n} . We obtain in all dimensions n⩾2 sharp dispersive and Strichartz estimates for a large family of admissible pairs.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Applications of extended F-expansion and projective Ricatti equation methods to (2+1)-dimensional soliton equations

open access: yesAIP Advances, 2013
The (2+1)-dimensional Maccari and nonlinear Schrödinger equations are reduced to a nonlinear ordinary differential equation (ODE) by using a simple transformation, various solutions of the nonlinear ODE are obtained by using extended F-expansion and ...
