Dense water formation in the Greenland Sea between 1999 and 2009
(Master thesis, 2019-08-22)A 10-year continuous hydrographic data record from moored profilers located in the central Greenland Sea between 1999 and 2009 were used to examine the mixed-layer depth evolution through winter as well as interannual ... -
The Departure from Mixed-Layer Similarity During the Afternoon Decay of Turbulence in the Free-Convective Boundary Layer: Results from Large-Eddy Simulations
(Journal article; Peer reviewed, 2023)This study analyses the departure of the velocity-variances profiles from their quasi-steady state described by the mixed-layer similarity, using large-eddy simulations with different prescribed shapes and time scales of ... -
Description and evaluation of the Bergen climate model: ARPEGE coupled with MICOM
(Peer reviewed; Journal article, 2003-07)A new coupled atmosphere–ocean–sea ice model has been developed, named the Bergen Climate Model (BCM). It consists of the atmospheric model ARPEGE/IFS, together with a global version of the ocean model MICOM including a ... -
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 ... -

Design of Grid-Tied Converter Using AFE
(Master thesis, 2023-03-18)The predicted increase in electricity demand from electrification of the transportation sector has led to research of bidirectional \gls{EV} chargers becoming an ever more popular research topic. With bidirectional chargers, ... -
Design of rectifier system for electric ferries
(Master thesis, 2018-06-16)This study investigates the requirements and technologies to provide power from shore to ship when the electric ferry is at quay. Different rectifier systems will be evaluated in terms of requirements given by the utility ... -

Detection and Timing of Gamma-Ray Pulsations from the 707 Hz Pulsar J0952−0607
(Journal article; Peer reviewed, 2019)The Low-Frequency Array radio telescope discovered the 707 Hz binary millisecond pulsar (MSP) J0952−0607 in a targeted radio pulsation search of an unidentified Fermi gamma-ray source. This source shows a weak energy flux ... -
The Determination of the Snow Optical Grain Diameter and Snowmelt Area on the Greenland Ice Sheet Using Spaceborne Optical Observations
(Journal article; Peer reviewed, 2022)The optical diameter of the surface snow grains impacts the amount of energy absorbed by the surface and therefore the onset and magnitude of surface melt. Snow grains respond to surface heating through grain metamorphism ... -
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 ... -
Development and Comparison of Compressor Models for Heat Pump Applications in TRNSYS
(Master thesis, 2018-06-22)Heat pump systems may serve as a replacement for many heating systems using fossil fuels for heating purposes. Heat pumps are widely used in Norway where electric energy is abundant and inexpensive. Research and development ... -
The development and evaluation of an idealized ocean model for the Bergen Dynamic Model
(Master thesis, 2013-11-20)Three idealized ocean model versions are developed for the Bergen Dynamic Model (Bedymo). All three model versions fall into the category of slab ocean models. One version is more or less a standard slab ocean model, while ... -
Development of a new urban climate model based on the model PALM – Project overview, planned work, and first achievements
(Journal article; Peer reviewed, 2019)In this article we outline the model development planned within the joint project Model-based city planning and application in climate change (MOSAIK). The MOSAIK project is funded by the German Federal Ministry of Education ... -
Development of advanced tools in computational nonlinear aeroelasticity
(Master thesis, 2023-01-04)In this work, the development of a two dimensional computational model for predicting the aeroelastic response is presented. In the aeroelastic model presented here, the aeroedynamic and the structural models are considered ... -
Development of an atmospheric chemistry model coupled to the PALM model system 6.0: implementation and first applications
