Investigation of Hydrodynamic Aspects of the Design of the Universal Buoyancy Concept (UBC) Loading Buoy
(Master thesis, 2012)A new loading and discharge concept for ships, referred to as the Universal Buoyancy Concept (UBC), is proposed as an effective alternative to land based infrastructure for distribution of primarily LNG. The UBC system ... -
Investigation of Hydrodynamic Performance of a Twin-Screw Trawler Using CFD
(Master thesis, 2015)Previously experimental methods or empirical knowledge laid the foundation for ship design. Performing a model test in a towing tank is time consuming and expensive. In addition to this, studying detailed effects in a ... -
Investigation of Hydrogel Scaffolds for Future Development of an In Vitro Alveoli Model of Human Pulmonary Fibroblasts
(Master thesis, 2023)Hovedmålet med denne masteroppgaven var å finne en egnet hydrogel som strukturelement for humane lungefibroblaster (HPFa) for å muliggjøre en fremtidig utvikling av en in vitro alveole modell. En lungealveole-modell kan ... -
Investigation of hydrogen embrittlement behavior in X65 pipeline steel under different hydrogen charging conditions
(Journal article; Peer reviewed, 2022)The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ hydrogen charging conditions. The fractured samples were characterized and compared using a combination of scanning ... -
Investigation of IDAES and optimization for a SMR process
(Master thesis, 2022)Naturgass er en ressurs som stadig blir mer beleilig å bruke som ressurs for energi med en verden som bestandig forandrer seg og med menneskeheten som innser at verden må gå mot et mer vennlig standpunkt i forhold til klimaet. ... -
