Theoretical Studies in Solar Cell Physics
(Doctoral Dissertations at the University of Agder; no. 390, Doctoral thesis, 2022)In this thesis, we develop analytical models with the purpose of expanding knowledge and gaining understanding of some of the internal mechanisms that limit the efficiency of single-junction solar cells. We focus on three ... -
Modelling and Detecting Faults of Permanent Magnet Synchronous Motors in Dynamic Operations
(Doctoral Dissertations at the University of Agder; no. 384, Doctoral thesis, 2022)Permanent magnet synchronous motors (PMSMs) have played a key role in commercial and industrial applications, i.e. electric vehicles and wind turbines. They are popular due to their high efficiency, control simplification ... -
An Access Control Model to Facilitate Healthcare Information Access in Context of Team Collaboration
(Doctoral Dissertations at the University of Agder; no. 208, Doctoral thesis, 2018)The delivery of healthcare relies on the sharing of patients information among a group of healthcare professionals (so-called multidisciplinary teams (MDTs)). At present, electronic health records (EHRs) are widely utilized ... -
Modeling and Control of Flexible Link Manipulators
(Doctoral Dissertations at the University of Agder; no. 373, Doctoral thesis, 2022)Autonomous maritime navigation and offshore operations have gained wide attention with the aim of reducing operational costs and increasing reliability and safety.
