Evaluating natural degassing in a river to create a baseline for comparison to technical degassing methods.
(Peer reviewed; Journal article, 2023)In Norway, a recent project used a risk matrix to identify about 200 hydropower plants ( 11 % of the total number) of being in high risk of producing air-supersaturated water. The combined installed capacity of these ... -
Pile design for X-rotor offshore wind turbine
(Peer reviewed; Journal article, 2023)For the foundations of traditional offshore structures in oil and gas industry, the dominant load is in vertical direction. For wind turbines, especially for vertical axis wind turbines, the lateral loads are increased ... -
VAWT support structure mass sensitivity due to aerodynamic load scaling
(Peer reviewed; Journal article, 2023)The X-rotor wind turbine is an X-shaped hybrid vertical axis wind turbine whose power take-off is done by horizontal axis rotors located at the tip of the lower blades. Based on an initial basic study, the present study ... -
Selective recovery of silver from copper impurities by electrodialysis: Tailoring monovalent selective cation exchange membranes by monomolecular layer deposition
(Peer reviewed; Journal article, 2023)Selective recovery of silver from secondary resources enriched with copper impurities is a well-known challenge but is urgently needed by the industry. This study addresses the challenge by developing a highly efficient ... -
Challenges faced by the stakeholders during a phase transition in a collaborative delivery project
(Master thesis, 2023)Formålet med denne masteroppgaven er å undersøke utfordringene og de bakenforliggende årsakene til disse utfordringene, samt å finne mulige løsninger for å løse disse utfordringene som aktørene står overfor under en ... -
A Decentralized Droop-Based Power Management System for Ship Power Systems Using Hybrid Dynamical Systems Framework
(Chapter, 2023)In maritime transport, inspired by the automobile sector, autonomy is gaining traction in parallel with decarbonization. One of the numerous challenges in realizing fully autonomous operation in shipping is to design a ... -

(Master thesis, 2023)This master’s thesis explores the realm of mega infrastructure projects, specifically examining the 1915 Çanakkale Bridge project in Turkey as a case study. The study’s motivation arises from the Norwegian Public Road ... -
Investigating the Interaction between Degradation and Thermal Behaviour in Lithium-Ion Batteries
(Doctoral theses at NTNU;2023:446, Doctoral thesis, 2023)The overall aim of this thesis is to generate knowledge on the interplay of battery degradation and thermal behaviour. We focused on the temperature dependency of degradation on the one hand and on the effect of degradation ... -
Buckling and Post-Buckling Behaviour of Extruded Aluminium Panels Subject to the Combined Effects of Welding and Pitting Corrosion
(Chapter, 2023)The present study investigates the effects of pitting corrosion and welding, both independently and combined, on the buckling and post-buckling behaviour of extruded aluminium panels. For this purpose, a finite element ... -
Flexible operation of Francis turbines
(Doctoral theses at NTNU;2023:387, Doctoral thesis, 2023)With the planned cuts in emissions, more of the electric energy will have to come from renewable sources. Two of the largest potential sources are wind- and solar, which have the downside of also being intermittent and ... -
