100-year waves in the Mozambique Channel
(Master thesis, 2010-06-01)Six-hourly significant wave height (SWH) data covering the period September 1957 to August 2002 is obtained from the ERA-40 reanalysis. This data, generated by ECMWF's own configured global WAM model, stems from the first ... -
3D mechanical and thermal analysis of an Aluminium piston for a high-speed Diesel laboratory engine
(Master thesis, 2018-06-22)A cast aluminium piston of a single cylinder Petter Diesel engine is modelled using the finite element method. The engine is intended to be supercharged, which will increase the thermal loading on the piston, and so the ... -
A POD-Based Reduced Order Model for Offshore Wind Applications, using LiDAR Measurements and WRF-PALM Simulations
(Master thesis, 2022-06-03)Wind flow fields within a wind farm, including wake dynamics, are a complex system of large degrees of freedom. The wake shape and velocity deficit downstream of a turbine may be calculated using numerical modeling, such ... -
Akvakultur og små vindturbinar: Eit moglegheitsstudie av i kva grad små vindturbinar kan dekkje energiforbruket ved norske oppdrettsanlegg
(Master thesis, 2018-06-21)The world’s population is growing rapidly, and it will become necessary, to a greater extent, to use the ocean for harvesting food. Norway is the largest exporter of salmon in the world. Prognosis says that aquaculture in ... -
An Investigation of the Optical Properties of Metal Nanoparticles for the Application in a Diffuse Light Solar Cell
(Master thesis, 2020-06-25)The need of renewable energy is increasing as the global energy demand increases concurrently with greenhouse gas emissions from energy use. According to the International Energy Agency, the energy demand will rise by 1.3 ... -
Analyse av energi, eksergi og eksergoøkonomi for en stempelmotorbasert CHP-enhet kombinert med en organisk Rankine-syklus (ORC)
(Master thesis, 2015-08-17)Waste heat recovery is a concept that is relevant for reducing consumption and emissions from thermal machinery. Waste heat recovery can performed in two ways: by Combined Heat and Power production (CHP) or Waste Heat ... -
Analyses of the potential role of hydrogen for Norway in the transition to a zero-emission society
(Master thesis, 2017-06-23)The objective of this thesis is to analyze the potential role of hydrogen for Norway in the transition to a zero-emission society. The main sector of focus is the transport sector. Here, socioeconomic analyses are carried ... -
Analysis of 3 years of precipitation measurements from the Micro Rain Radar located at the Geophysical Institute
(Master thesis, 2013-11-20)An analysis of three years of vertically pointing Micro Rain Radar (MRR) data from the measurement platform at the Geophysical Institute has been performed. The measurement period started at 13.04.2010 and ended at 12.04.2013. ... -
Annual and Seasonal Mean Net Evaporation Rates of the Red Sea Water during Jan 1958 - Dec 2007
(Master thesis, 2012-10-01)Data set including sea level, temperature, salinity, and current from Simple Ocean Data Assimilation (SODA) is used in this study to estimate the mean net annually and seasonally evaporation rates. Then wind data is used ... -
Application of the unmanned Offshore Sensing SailBuoy for validation of ocean model simulations and remote sensing data in the North Atlantic
(Master thesis, 2015-12-01)The Offshore Sensing SailBuoy, is a remotely controlled, wind driven unmanned ocean vehicle. It sampled near surface properties during a mission in the North Atlantic in June - August 2014. Three parameters were recorded, ... -
The Arctic Sea Ice - Melting During Summer or not Freezing in Winter?
(Master thesis, 2016-06-01)The Arctic sea ice cover has retreated rapidly during the last three decades, concurrent with recent global temperature increase both in the atmosphere and in the ocean. The sea ice cover has experienced a retreat in extent ... -
Atmospheric response to removal of Southern Hemisphere sea ice - a model study
(Master thesis, 2010-06-01)The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ... -
Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study
(Master thesis, 2008-05-29)A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ... -
Avvik mellom estimert og faktisk energiproduksjon for småkraftverk
(Master thesis, 2016-06-01)I denne oppgaven har jeg sett på årsakene til avviket mellom estimert og faktisk energiproduksjon for tre av kraftverkene som Småkraft AS sammen med grunneier har hatt i drift i 8-9 år. Kraftverkene jeg har sett på er Ytre ... -
Batterilading i hybride fremdriftssystemer ved hjelp av tapsenergi fra forbrenningsmotoren
(Master thesis, 2017-06-23)In a time when emission standards are getting stricter, the search for more environmentally friendly propulsion is more relevant than ever. Hybridization and electric propulsion has, thus, become more common in some sectors, ... -
Benguela Niños: Observations and Modelling
(Master thesis, 2004)A numerical ocean model for the South Atlantic was used to study the 1995 Benguela Niño in order to learn about the underlying forcing mechanisms of the phenomenon. By comparing observations and model output, it was found ... -
