High-order regularized regression in Electrical Impedance Tomography
Nick Polydorides, Alireza Aghasi, Eric L. Miller
We present a novel approach for the inverse problem in electrical impedance tomography based on regularized quadratic regression. Our contribution introduces a new formulation for…
Sensitivity Calculations for the Poisson's Equation via the Adjoint Field Method
Alireza Aghasi, Eric L. Miller
Adjoint field methods are both elegant and efficient for calculating sensitivity information required across a wide range of physics-based inverse problems. Here we provide a unifi…
A Hybrid Global Minimization Scheme for Accurate Source Localization in Sensor Networks
Hamidreza Aghasi, Hamidreza Amindavar, Alireza Aghasi
We consider the localization problem of multiple wideband sources in a multi-path environment by coherently taking into account the attenuation characteristics and the time delays…
