Investigation of the possibilities for seabottom characterization using echosounder data
(Master thesis, 2009-11-18)This thesis focuses mainly on using the information present in the first echo returned from the seafloor, using a normal-incidence echosounder, to characterize or classify the seabed. This is done using a monostatic setup ... -
Modeling trapping mechanism of PCB on activated carbon
(Master thesis, 2009-11-20)This thesis aims to investigate the trapping mechanism of polychlorinated biphenyls (PCB) on activated carbon. In the pursuit of this goal, molecular dynamics (MD) simulations were the method chosen. To be able to model a ... -
Hydratdannelse og metanproduksjon fra gasshydrat - produksjonsmetoder og resistivitetsutvikling
(Master thesis, 2009-11-20)Ved høye trykk og lave temperaturer kan vannmolekyler danne strukturelle bur rundt et gjestemolekyl. Denne substansen er da i fast form og kalles hydrat. I naturlig forekomst av gasshydrat er metan det vanligste gjestemolekylet. ... -
PVCap as kinetic hydrate inhibitor in gas-water system
(Master thesis, 2009-11-20)In this work, molecular dynamic (MD) simulations were employed on different model systems of practical and theoretical significance to investigate possible mechanisms of kinetic hydrate inhibition. Water/methane interface ... -
