We develop two closely-related fast and simple numerical algorithms to address the inverse problem of identifying a collection of disjoint linear cracks in a two-dimensional homogeneous electrical conductor from exterior boundary voltage/current measurements. We allow the possibility that the cracks are partially conductive. Our approach also allows us to determine the actual number of cracks present, as well as make use of one or multiple input fluxes. We illustrate our algorithms with a…

Non-Destructive Recovery of Voids within a Three Dimensional Domain Using Thermal Imaging
We develop an algorithm capable of detecting the presence of spherical voids in a thermally conducting object. In addition, the process recovers both the radii and locations of each void. Our method
Some novel approaches in modelling and image reconstruction for multi-frequency Electrical Impedance Tomography of the human brain
Novel generic tools were developed in order to enable modelling and non-linear image reconstruction of large-scale problems, such as those arising from the head EIT problem.

Abstract We consider the problem of determining the location and the size of a linear crack in an electrically conducting two dimensional medium. The probing device consists of a single pair of

We consider the problem of identification of a collection of a finite number of cracks in a planar domain. It is proved that the location and shape of any finite number of cracks can be determined
Recovery of cracks using a point-source reciprocity gap function
In this work we consider the recovery of internal cracks from boundary measurements. We will use a function that we call point-source reciprocity gap function, which may be obtained as a particular

This paper deals with a semi-explicit algorithm to reconstruct two-dimensional (2D) segment cracks, or three-dimensional (3D) planar cracks, in the framework of overspecified boundary data. The
Identification of simple poles via boundary measurements and an application of EIT
We consider the problem of identifying simple poles of a meromorphic function by means of the value of the function measured on a circle enclosing those poles. We propose an algorithm for this
