Razumikhin-type Theorems on Practical Stability of Dynamic Equations on Time Scales

Bacem Ben Nasser, Michael Defoort, Mohamed Djemai, Taous-Meriem Laleg-Kirati

In this work, we investigate some Razumikhin-type criteria for the uniform global practical asymptotic stability on arbitrary time domains, for time-varying dynamic equations. Using Lyapunov-type functions on time scales, we develop appropriate inequalities ensuring that trajectories decay to the...

Estimates of oscillatory integrals with stationary phase and singular amplitude: Applications to propagation features for dispersive equations

Florent Dewez

In this paper, we study time‐asymptotic propagation phenomena for a class of dispersive equations on the line by exploiting precise estimates of oscillatory integrals. We propose first an extension of the van der Corput Lemma to the case of phases which may have a stationary point of real order and...

An Incremental Physically-Based Model of P91 Steel Flow Behaviour for the Numerical Analysis of Hot-Working Processes

Alberto Murillo-Marrodán, Eli Saúl Puchi-Cabrera, Eduardo Garcia, Mirentxu Dubar, Fernando Cortes, Laurent Dubar

This paper is aimed at modelling the flow behaviour of P91 steel at high temperature and a wide range of strain rates for constant and also variable strain-rate deformation conditions, such as those in real hot-working processes. For this purpose, an incremental physically-based model is proposed...

Mesh Twisting Technique for Swirl Induced Laminar Flow Used to Determine a Desired Blade Shape

Asdis Helgadottir, Sylvain Lalot, François Beaubert, Halldor Pálsson

Swirling flow has been shown to increase heat transfer in heat exchangers. However, producing swirl while not presenting a severe pressure drop can be a challenge. In this paper, a desired shape of guidance blades for laminar swirl flow is determined by numerical simulation in OpenFOAM. Emphasis is...

High performance LDPC codes for high spectral efficiency

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Achieving high spectral efficiency is the key requirement of future wireless systems and mobile communications because it provides us a high quality for high data over a limited bandwidth. In order to achieve high spectral efficiency, channel coding and modulation are the key part. Basically, high...

Characterization of a visco-hyperelastic synthetic gel for ballistic impacts assessment

Anthony Bracq, Grégory Haugou, Benjamin Bourel, Rémi Delille, Christophe Maréchal, Franck Lauro, Sébastien Roth, Olivier Mauzac

Understanding the human body response during impact has become a primary concern, especially in the field of ballistic impacts. Among various materials employed as human body substitutes, synthetic gel named SEBS is used in the present study. Mechanical characterization from quasi-static to very...

Fragment d’une Continuation de la Chanson de Jérusalem

Jean-Charles Herbin, Gauthier Grüber

Le passage contenu dans ce fragment de la Continuation de la Chanson de Jérusalem se situe juste après l’empoisonnement de Godefroi de Bouillon par le patriarche Éracle et Tangré de Pouille ; le texte en est plutôt remanié dans le détail par rapport aux deux seuls manuscrits connus de la chanson,..., The passage contained in this fragment of the Continuation de la Chanson de Jérusalem is situated just after the poisoning of Godefroi de Bouillon by the patriarch Éracle and Tangré de Pouille ; the text was reworked in detail in comparison to the two known manuscripts of the chanson, even though...
