Monitoring Soil Moisture Drought over Northern High Latitudes from Space
(Peer reviewed; Journal article, 2019-05-20)Mapping drought from space using, e.g., surface soil moisture (SSM), has become viable in the last decade. However, state of the art SSM retrieval products suffer from very poor coverage over northern latitudes. In this ... -
A comparative study of Doubly Fed Asynchronous and Synchronous Generators in a wind energy perspective
(Master thesis, 2019-06-15)Dette masterstudiet fokuserer på analyse av vindkraft-generatorer. Det er et sammenligningsstudie av den dobbel-matede asynkrongeneratoren og synkrongeneratorer, hvor effektivitet, driftsforhold og økonomiske perspektiv ... -
Characterization of a Geothermal Field using Multiscale Travel Time Tomography - A study of the Miravalles Geothermal Field in Costa Rica
(Master thesis, 2019-06-15)The objective of this thesis is to investigate how travel time tomography and earthquake relocations can improve the understanding of the Miravalles geothermal field in Costa Rica. Finding the answer to this research ... -
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 ... -
Air-Sea Interactions during Cold Air Outbreaks in a coupled Mixed Layer Model
(Master thesis, 2019-06-19)Cold air outbreaks play a crucial role in the air-sea heat exchange in high latitudes. To explore the sensitivity to ocean coupling, the role of latent heating and the sensitivity to sea ice distributions in cold air ... -
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 ... -
The importance of wind turbulence and coherence to the loads on a wind turbine blade
(Master thesis, 2019-06-25)The wind simulation method proposed by Paul S. Veers from Sandia National Laboratories has been checked for the measured wind velocities at 40m and 80m height at FINO1 platform. The Sandia method applied as it is, gives ... -
The Atmospheric Surface Layer over Dronning Maud Land, Antarctica
(Master thesis, 2019-06-28) -
Airborne Field Measurements and Model Simulations of Boundary Layer Properties over the Iceland Sea
(Master thesis, 2019-06-28)The spatial and temporal distributions of a cold air outbreak (CAO) event over the Iceland- and southern Greenland Seas have been investigated during the IcelandGreenland Seas project (IGP) in February and March 2018. This ... -
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 ... -
Undersøkelse av reaksjonsmekanismer for OMEbrennstoff for bruk til implementering i 3D-CFD simulering av forbrenning
(Master thesis, 2019-06-28)Oxymetylene etere (OME) er brennstoff som brenner så og si uten utslipp av sot. Disse syntetisk skapte brennstoffene kan spille en viktig rolle i diesel miksen en dag, og kanskje til og med et surrogat for diesel. Brennstoffet ... -
