Reducing crosstalk in array structures by controlling the excitation voltage of individual elements : a feasibility study

Abdelmajid Bybi, Sébastien Grondel, Jamal Assaad, Anne-Christine Hladky, Christian Granger, Mohamed Rguiti

This paper describes a procedure to minimize crosstalk between the individual elements of a piezoelectric transducer array. A two-dimensional finite elements model was developed and the excitation voltages predicted by the model were applied to the array prototypes made of PZT 27 ceramic. Symmetric...

Residual-based a posteriori estimators for the T/Omega magnetodynamic harmonic formulation of the Maxwell system

Emmanuel Creusé, Serge Nicaise, Zuqi Tang, Yvonnick Le Menach, Nicolas Nemitz, Francis Piriou

In this paper, we focus on an a posteriori residual-based error estimator for the T/Omega magnetodynamic harmonic formulation of the Maxwell system. Similarly to the A/Phi formulation, the weak continuous and discrete formulations are established, and the well-posedness of both of them is addressed...

Frittage micro-ondes en cavité monomode de biocéramiques

Etienne Savary, Anthony Thuault, Jean-Christophe Hornez, Michel Descamps, Sylvain Marinel, Anne Leriche

Le but premier de cette étude est de montrer la faisabilité du frittage direct en cavité micro-ondes monomode de deux biomatériaux céramiques : l'hydroxyapatite et le phosphate tri-calcique. Ainsi, cette étude montre que ce procédé a permis d'obtenir, en des temps très courts, inférieurs..., The main purpose of this study consists in investigating the direct microwaves sintering in a single mode cavity of two bioceramics: hydroxyapatite and tri-calcium phosphate. Thus, dense samples presenting fine microstructures are successfully obtained in less than 20 minutes of irradiation. The...

Dispersive waves with multiple tunnel effect on star shaped networks

Felix Ali Mehmeti, Robert Haller-Dintelmann, Virginie Régnier

We consider the Klein-Gordon equation on a star-shaped network composed of n half-axes connected at their origins. We add a potential which is constant but dierent on each branch. The corresponding spatial operator is self-adjoint and we state explicit expressions for its resolvent and its...

Polynomial decay rate for a wave equation with general acoustic boundary feedback laws

Serge Nicaise, Zainab Abbas

We consider the stabilization of the wave equation by a general class of acoustic boundary feedback laws at one extremity. This system is not uniformly stable but we furnish sufficient conditions that guarantee a polynomial stability. Our method combines the use of an observability inequality for...

Numerical approximation for options pricing of a stochastic volatility jump-diffusion model

Rajae Aboulaich, Fouzia Baghery, Abdelilah Jraifi

In this paper, we are interested in pricing options (European and Quanto) by a Model in which the asset prices follow a jump-diffusion model with a stochastic volatility in n dimensions. The stochastic volatility also follows the jump-diffusion in d dimensions. We've already stated the...

Convergence order of a numerical scheme for sweeping process

Frederic Bernicot, Juliette Venel

In a previous paper, an implementable algorithm was introduced to compute discrete solutions of sweeping processes (i.e. specific first order differential inclusions). The convergence of this numerical scheme was proved thanks to compactness arguments. Here we establish that this algorithm is of...
