Anthropogenic Carbon in the Nordic seas and Arctic Ocean, 1994 to 2007
(Master thesis, 2019-06-28)The increase of anthropogenic CO2 between 1994 and 2007 is quantified in the Nordic seas and Arctic Ocean with the extended multiple linear regression method (eMLR(C*)). To be able to map the increase in anthropogenic CO2 ... -
Atlantic Multidecadal Variability (AMV) in the Norwegian Earth System model
(Master thesis, 2020-06-26)The causes of low-frequency sea surface temperature (SST) variations in the Atlantic, known as Atlantic Multidecadal Variability (AMV), are debated. AMV has climatic impacts on for instance hurricane activity and Sahel ... -
Bidirectional DC-DC Converter For Charging Batteries of Electric Vehicles
(Master thesis, 2021-06-01)The popularity of electric vehicles has seen significant growth in the latest years. More electric vehicles are connected to the grid, and the load is increased consequently. The electric vehicle battery can be employed ... -
Bidirectional DC-DC Converter for Supercapacitor as DC-bus Stabilization Element
(Master thesis, 2021-06-01)The demand for renewable energy from wind and solar is increasing. These energy sources are intermittent and unpredictable to a degree and require a stable but fast responding DCgrid. This is achieved by extending the ... -

Hydropower Production Scheduling using Stochastisc Dual Dynamic Programming subject to environmental constraints
(Master thesis, 2019-06-22)Oppgaven utforsker vannkraftproduksjonsplanlegging i Bergsdalen vassdraget, styrt av BKK, ved hjelp av Stokastisk Dual Dynamisk Programmering. Systemet er under et sett med miljørestriksjoner, innført av NVE, som utfordrer ... -
Ignition of high-pressure hydrogen releases – Experimental study of impinging and non-impinging releases through a fast-acting valve, with and without a burst disc downstream of the valve
(Master thesis, 2021-09-14)A wide consensus of climate research indicates that anthropogenic greenhouse gas emissions affect the climate and causes the global mean temperature to rise compared to preindustrial levels. International treaties such as ... -
Impacts on carbon budgets of increased use og Norwegian forest resources for energy
(Master thesis, 2019-06-19)When forests are logged for heat and electricity production, emissions from burning of the biomass are not accounted for in national greenhouse gas reporting to the climate convention. This would have been correct if a ... -
Investigation of the dynamic response of a spar FOWT, and its sensitivity to variations in draft
(Master thesis, 2020-06-30)The objective of this thesis is to investigate how the dynamic properties of a spar supported FOWT change when the draft is reduced, and what draft is needed in order to support a 10 MW wind turbine. Design solutions of ...
