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...

Analytical model for the energy harvesting of a spherical sensor from ambient vibrations

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Adnan Naja, Fawaz El Omar

In this work an analytical model for the energy harvesting of an acoustic spherical sensor has been developed in the context to make it autonomous. Our spherical sensor is composed of two half-spheres of Plexiglas and a piezoelectric ring of PZ26 that can be used as exciter or sensor. For the...

Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3

Bart Dioos, Luc Vrancken, Xianfeng Wang

In this paper, we investigate Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3. We introduce and make use of a triplet of angle functions to describe the geometry of a Lagrangian submanifold in S3×S3. We construct a new example of a flat Lagrangian torus and give a complete...
