Application of the MFS to inverse obstacle scattering problems
(2011)In this paper, the method of fundamental solutions (MFS) is used to detect the shape, size and location of a scatterer embedded in a host acoustic homogeneous medium from scant measurements of the scattered acoustic pressure ...

Article
Detection of cavities using the method of fundamental solutions
(2009)The determination of the boundary of a cavity, defined here as a perfectly insulated inclusion, within a conducting medium from a single voltage and current flux measurements on the accessible boundary of the medium, can ...

Article
An inverse method to assign receptances by using classical vibration absorbers
(2009)The classical massspring absorber can be thought of as a very simple structural modification. In this paper the inverse problem of assigning receptances to a dynamic system by using one or more simple massspring absorbers ...

Article
A meshless numerical identification of a soundhard obstacle
(2012)We propose a simple meshless method for detecting a rigid (soundhard) scatterer embedded in a host acoustic homogeneous medium from scant measurements of the scattered near field. This inverse problem is illposed since ...

Article
The method of fundamental solutions for an inverse boundary value problem in static thermoelasticity
(2014)The inverse problem of coupled static thermoelasticity in which one has to determine the thermoelastic stress state in a body from displacements and temperature given on a subset of the boundary is considered. A regularized ...

Article
The method of fundamental solutions for solving direct and inverse Signorini problems
(2015)Signorini problems model phenomena in which a known or unknown portion of the boundary is subjected to alternating Dirichlet and Neumann boundary conditions. In this paper, we apply the method of fundamental solutions (MFS) ...

Article
The method of fundamental solutions for the detection of rigid inclusions and cavities in plane linear elastic bodies
(2012)We investigate the numerical reconstruction of smooth starshaped voids (rigid inclusions and cavities) which are compactly contained in a twodimensional isotropic linear elastic body from a single nondestructive measurement ...

The method of fundamental solutions for the inverse conductivity problem
(2010)In this article, we propose a simple method for detecting an inclusion Ω2 embedded in a host electrostatic medium Ω1 from a single Cauchy pair of voltage and current flux measurements on the exterior boundary of Ω1. A ...

The MFS for numerical boundary identification in twodimensional harmonic problems
(2011)In this study, we briefly review the applications of the method of fundamental solutions to inverse problems over the last decade. Subsequently, we consider the inverse geometric problem of identifying an unknown part of ...

The MFS for the Cauchy problem in twodimensional steadystate linear thermoelasticity
(2013)We study the reconstruction of the missing thermal and mechanical fields on an inaccessible part of the boundary for twodimensional linear isotropic thermoelastic materials from overprescribed noisy (Cauchy) data on the ...

Article
The MFS for the identification of a soundsoft interior acoustic scatterer
(2017)We employ the method of fundamental solutions (MFS) for detecting a soundsoft scatterer surrounding a host acoustic homogeneous medium due to a given point source inside it. The measurements are taken inside the medium ...

A moving pseudoboundary MFS for threedimensional void detection
(2013)We propose a new moving pseudoboundary method of fundamental solutions (MFS) for the determination of the boundary of a threedimensional void (rigid inclusion or cavity) within a conducting homogeneous host medium from ...

A moving pseudoboundary MFS for void detection in twodimensional thermoelasticity
(2014)We investigate the numerical reconstruction of smooth starshaped voids contained in a twodimensional isotropic linear thermoelastic material from the knowledge of a single nondestructive measurement of the temperature ...
