Elvetun, Ole Løseth (PhD Thesis;2015:84, Doctoral thesis, 2018-04-30)This thesis is mainly concerned with the efficient numerical solution of optimization problems subject to linear PDE-constraints, with particular focus on robust preconditioners and diffuse domain methods. Associated with ...
Preconditioners for PDE-constrained optimization problems with box constraints: Towards high resolution inverse ECG images Elvetun, Ole Løseth; Nielsen, Bjørn Fredrik (Journal article; Peer reviewed, 2017)
The inverse problem of electrocardiography : increasing the stability by using a simplified geometry for the ischemic region Elvetun, Ole Løseth (Master thesis, 2012-04-27)We aim to obtain stability when using ECG recordings, the bidomain model and lab measurements to locate an ischemic region in the heart. Historically, this has proven to be a difficult task when using a general geometry, ...
