A nonsmooth primal-dual method with interwoven PDE constraint solver
Bjørn Jensen, Tuomo Valkonen
We introduce an efficient first-order primal-dual method for the solution of nonsmooth PDE-constrained optimization problems. We achieve this efficiency through not solving the PDE…

Conductivity reconstruction from power density data in limited view
Bjørn Jensen, Kim Knudsen, Hjørdis Schlüter
In Acousto-Electric tomography, the objective is to extract information about the interior electrical conductivity in a physical body from knowledge of the interior power density d…
