BREIT: A Framework for Brain Stroke Reconstruction using Multi-Frequency 3D EIT
Djahid Abdelmoumene, Ishak Ayad, Maï K. Nguyen +1
Multi-Frequency Electrical Impedance Tomography (MF-EIT) is a non-invasive, low-cost modality that reconstructs electrical property distributions from boundary voltages. For stroke…
High Order Impedance Boundary Condition for the Three-dimensional Scattering Problem in Electromagnetism
Soumaya Oueslati, Christian Daveau, Abil Aubakirov
In this paper, we propose a variational formulation with the use of high order impedance boundary condition (HOIBC) to solve the scattering problem. We study the existence and uniq…
A new variational formulation with high order impedance boundary condition for the scattering problem in electromagnetism
Soumaya Oueslati, Christian Daveau, Abil Aubakirov
In this paper, we propose some variational formulations with the use of high order impedance boundary condition (HOIBC) to solve the scattering problem. We study the existence and…
Unique determination of electromagnetic parameters from partial boundary measurements
Christian Daveau, Abdessatar Khelifi, Houssem Lihiou
We consider an inverse boundary value problem for the Maxwell's equations with a given data assumed to be known only in accessible part of the boundary. We aim to prove an uniq…
Asymptotic behaviors for eigenvalues and eigenfunctions associated to Stokes operator in the presence of small boundary perturbations
Christian Daveau, Abdessatar Khelifi
We consider the Stokes eigenvalue problem in a bounded domain of R3 with Dirich- let boundary conditions. The aim of this paper is to advance the development of high-order terms in…
A posteriori error estimates for discontinuous Galerkin method to the elasticity problem
Thi Hong Cam Luong, Christian Daveau
This work concerns with the discontinuous Galerkin (DG)method for the time-dependent linear elasticity problem. We derive the a posteriori error bounds for semi-discrete and fully…
