Global solutions for abstract impulsive neutral differential equations [PDF]

, 2011
We study the existence of mild solutions for a class of impulsive neutral functional differential equation defined on the whole real axis. Some concrete applications to ordinary and partial neutral differential equations with impulses are considered. (C)

Oscillation of solutions of second order mixed nonlinear differential equations under impulsive perturbations [PDF]

, 2011
New oscillation criteria are obtained for second order forced mixed nonlinear impulsive differential equations of the form (r(t)Φα(x′))′+q(t)Φα(x)+∑k=1nqk(t)Φβk(x)=e(t),t≠θix(θi+)=aix(θi),x′(θi+)=bix′(θi) where Φγ(s):=|s|γ−1s and β1>β2>⋯>βm>α>βm+1>⋯>βn>0.

On observability of switched differential-algebraic equations [PDF]

, 2010
— Based on our previous work dealing with geomet-ric characterization of observability for switched differential-algebraic equations (switched DAEs), we propose an observer design for switched DAEs that generates an asymptotically con-vergent state ...

Mixed-order impulsive ordinary and fractional differential equations with initial conditions [PDF]

Advances in Difference Equations, 2019
Dans cet article, en utilisant l'idée d'intervalles séparés dans les équations impulsives non instantanées, nous commençons l'étude des problèmes de valeur initiale pour les équations différentielles ordinaires et fractionnaires d'ordre mixte avec des effets impulsifs instantanés.

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

Advanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...
