On the parameterization of ill-posed inverse problems arising from elliptic partial differential equations
Electric impedance tomography (EIT) consists in finding the conductivity inside a body from electrical measurements taken at its surface. This is a severely ill-posed problem: any numerical inversion scheme requires some ...
Resistor Network Approaches to the Numerical Solution of Electrical Impedance Tomography with Partial Boundary Measurements
Electrical Impedance Tomography (EIT) problem consists of finding the electric conductivity inside a conductive body from simultaneous measurements of electric potential and current at its boundary. The EIT problem with ...
Filtering random layering effects for imaging and velocity estimation
Imaging compactly supported reflectors in highly heterogeneous media is a challenging problem due to the significant interaction of waves with the medium which causes considerable delay spread and loss of coherence. The ...
Imaging in cluttered acoustic waveguides
We consider an inverse problem for the acoustic scalar wave equation in a cluttered waveguide. The problem is to find the location of sources or scatterers, given measurements of the pressure at a remote array of transducers. ...
