This paper investigates numerically the Galerkin Least Square method for time-harmonic acoustic simulation within the virtual church of Royaumont abbey. The church's history is here reviewed. Since this church was destroyed after the french revolution, the methodology to build an accurate computer aided design model of the church of Royaumont abbey is clearly detailed. The Helmholtz equation is considered...
The Galerkin Gradient Least Square method is here proposed to simulate the sound holography inside the church of the Royaumont abbey, which has been destroyed in 1792. The church is restored with a computer aided design model, which is then meshed by a voxelization algorithm for a finite element analysis. Helmholtz equation is used for modeling the acoustics phenomena. To increase the accuracy of...
Developing and deploying infrastructure-based indoor localization solutions face significant challenges in the need of specialized user devices, costly and elaborative installation, configuration and maintenance, and in some cases, low localization accuracy. In this work, we develop an acoustic indoor localization system that requires little configuration and can localize commercial off-the-shelf...
This paper deals with a non-overlapping domain decomposition method involving additional augmented terms along the interface between the sub-domains. The goal of these additional terms is to prevent the singularity of the sub-domain matrix problems, such as rigid body motion in mechanics or resonance frequencies in acoustics. If the definition of these augmented terms requires minor intrusion inside...
