(Master thesis, 2019-07-02) -
High Voltage Laboratory Development: An in-depth Description and Report on the Process of Fabricating a Faraday Cage
(Master thesis, 2022-12-16)This thesis examines the quality of protection a Faraday cage provides against electromagnetic fields. The necessary theory to examine and calculate the shielding effectiveness of a Faraday cage, discuss obtained results ... -
How effective is the Mann turbulence model in predicting horizontal turbulence from vertical data?
(Master thesis, 2024-06-03)Offshore wind turbines are approaching 300 m.a.s.l., where the dynamics of the atmospheric turbulence remain unclear. Present understanding is limited, with direct measurements above 100 m from the sea surface being scarce. ... -
Hydrogen Consumption by Halophilic Microorganisms - Implications for Underground Hydrogen Storage
(Master thesis, 2023-06-01)Underground Hydrogen Storage (UHS) in reservoirs and caverns is a possible solution for large-scale and long-term storage of hydrogen (H2) in the subsurface. As the cost of tech- nology installation and electricity from ... -
Hydrogen production from fluctuating small-scale hydropower
(Master thesis, 2024-06-03)As the world seeks renewable alternatives to fossil fuels, hydrogen emerges as a valuable energy carrier to facilitate the green shift. When produced from renewable energy, hydrogen is considered a green fuel that can be ... -
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 ... -
Hyperheuristic Frameworks for Combinatorial Optimization Problems using Deep Reinforcement Learning
(Master thesis, 2024-06-17)Many metaheuristic frameworks exist for solving different combinatorial optimization problems. Despite formulating general strategies that can be applied to many problems, they often rely on problem-specific implementation. ... -
Idealized Modeling of the North Icelandic Jet
(Master thesis, 2023-06-01)The North Icelandic Jet (NIJ) is a crucial component of the lower limb of the Atlantic Meridional Overturning Circulation, supplying one-third to one-half of the overflow water transport through Denmark Strait, including ... -
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 ... -
Investigating genesis and early development of Arctic cyclones using an isentropic analysis
(Master thesis, 2024-06-10)Cyclones are frequently found in the Arctic and can have wide-ranging impacts on the region. Nevertheless, few studies have focused on the development of cyclones originating in the Arctic, in contrast to the extensively ... -
Investigating the Southern Ocean Biogeochemical Divide
(Master thesis, 2024-06-03)The Southern Ocean plays a crucial role in Earth's climate and biogeochemical (BGC) cycles due to its unique features, such as strong westerly winds, intense ocean circulation, and its high-latitude location. This study ... -
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 ... -
Karbondynamikk i Grønlandshavet observert av en Argobøye og en 1-D Blandingsmodell
(Master thesis, 2023-06-02) -
Life cycle assessment of hydrogen fuel in aviation
(Master thesis, 2020-07-01)The aviation sector emits 2% of the global emissions caused by transportation. This is a problem for our global climate and has also shown to be an issue for the public after the Swedish boycott of airtravel, inspired by ... -
Long-term changes in the Nordic Seas' hydrographic structure and overflow waters
(Master thesis, 2020-06-30)A collection of historical hydrographic data was used to examine the hydrographic properties of the water masses in the Nordic Seas from 1950 to 2018, with particular focus on the dense overflows from the Nordic Seas. ... -
Low-level jet height’s impact on wind turbine loads: A case study
(Master thesis, 2023-06-01)Over the years, wind turbines have been steadily increasing in size, with newer models boasting larger dimensions. For instance, the diameter of an installed prototype offshore wind turbine in late 2022 was over 200 m, ... -
Machine learning for early detection of structure loss in the Czochralski process
