Developing the Tools to Quantify Past Climate Variability from Ice Core Records
(Doctoral thesis, 2023-06-21)Vannstabile isotoper registrert i iskjerner, brukes som proxydata for å rekonstruere klimaet i fortiden. Tradisjonell tolkning av registrerte vannisotoper er at snø fanger opp den integrerende isotopiske signaturen av ... -
Designbasis for metanpyrolysereaktor som forskningsreaktor ved HVL
(Master thesis, 2023-06-15) -
En eksperimentell oppgave på legeringer av silisium og jern
(Master thesis, 2023-06-06)Silisium og legeringer med silisium er viktige materialer innen forskjellige industrier og brukes blant annet som tilsetningsstoff. I flere typer industri brukes slike legerin- ger i form av pulver, både for enklere transport ... -
Karbondynamikk i Grønlandshavet observert av en Argobøye og en 1-D Blandingsmodell

Evaluating the quality of Controlled Meteorological Balloons in Arctic air mass transformation over the Nordic Seas
(Master thesis, 2023-06-01)In situ measurements from Controlled Meteorological (CMET) balloons are used to study Arctic air mass transformation in marine cold air outbreaks (mCAOs) over the Nordic Seas. 6 CMET balloons were launched from Ny- ̊Alesund ... -
An Experimental and Numerical Study of the Performance of Carbon Black Nanofluids in a Direct Absorption Solar Collector
(Master thesis, 2023-06-01) -
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 ... -
Microbial behavior and hydrogen consumption of Oleidesulfovibrio alaskensis - Implications for subsurface hydrogen storage
(Master thesis, 2023-06-01)To reduce global warming an energy transition going from fossil fuel to renewable energy is required and energy storage opportunities to store surplus electricity are needed. Hydrogen gas (H2) is an energy carrier and can ... -
Numerical Simulation of Nanofluid Cooling in a Single-Cylinder Diesel Engine
(Master thesis, 2023-06-01) -
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 ... -
Direkte bruk av nanofluider som kjølevæske i en dieselmotor
(Master thesis, 2023-06-01)The work carried out in this thesis is the characterization and investigation of carbon- based nanofluids as a potential engine coolant for a single-cylinder diesel engine. Car- bon black particles could be sufficiently ... -
SFY: A free-drifting wave buoy for measuring surf waves
(Master thesis, 2023-06-01)Breaking waves have been studied for over a century. Still, there is an insufficient understanding of wave breaking due to limited in situ data. The high variability and the energetic environment in the surf zone makes it ... -
Stochastic Optimization of Battery Storage: An Analysis of its Potential
(Master thesis, 2023-06-01) -
Wave Measurements Using Ship Mounted Sensors as part of the One Ocean Expedition
(Master thesis, 2023-06-01)This thesis examines the design and post-processing aspects of wave measurements from ship mounted sensors. The wave measurements exhibit accuracy comparable to wave measuring drifters while offering enhanced spatial ... -
On the use of car observations to evaluate and improve road weather forecasting

Design av Grid-tilkoblet Omformer for Energilagringssystemer
(Master thesis, 2023-06-01)I Norge har vi et veldig høyt elektrisitetsforbruk sett i forhold til kraft per innbygger, samt at en av våre konkurransefortrinn med tanke på industri er nettopp tilgangen til billig og grønn strøm. En utfordring med dette ... -
Experimental Investigation of Silicon Dust Explosions in Pipes
(Master thesis, 2023-06-01)Metallurgical silicon and its alloys are essential in several industries, such as solar energy, automotive, aerospace, and steel production. However, silicon dust, generated during silicon production, processing, and ... -
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, ...
