Analyse av nedbørstidsserie i forhold til atmosfærisk sirkulasjon over Ny-Ålesund (Svalbard) i perioden 1974 — 2017
Andersen, Aleksander Sivert Valdemar Dimitri Ghinea (Master thesis, 2018)In the Arctic, the temperature increase has been more than double of the global increase. The archipelago of Svalbard is among the regions in the Arctic where the observed climate change is at its biggest. Future climate ... -
Assimilation of GNSS observations in a nowcasting numerical weather prediction model
Sauge, Yngvild (Master thesis, 2020)Nowcasting, a very short-term weather forecasting, has been more and more used in the later years, due to improved forecast models and more computing power. More frequent weather forecast updates depend on observations ... -
Betydningen av demningsmagasin og av klimaendringer for energiproduksjonen i småkraftverk
Hwang, Edwige Solène (Master thesis, 2018)Denne masteroppgaven omhandler betydningen av demningsmagasin og av klimaendringer for energiproduksjonen i småkraftverk. Formålet er å undersøke hvordan energiproduksjonen i norske småkraftverk endres, dersom det forutsettes ... -
Combining mathematical programming and machine learning in electricity price forecasting
Sveen, Eivind Bekken (Master thesis, 2019)The future electricity market will have a higher share of generation from unregulated renewable energy sources because of binding targets for reducing CO2 emissions. Energy reserves for regulating the power production will ... -
Cybersikring av en operasjonell data lake
Haugen, Tommy (Master thesis, 2018) -
Daily temperature and precipitation variability in Scandinavia in a large ensemble simulation
Waage, Nina Marianne Nyeng (Master thesis, 2019)According to the last assessment report from the Intergovernmental Panel on Climate Change, due to human-induced climate changes, alterations in future temperature and precipitation are expected, and we will have a higher ... -
Development of electroluminescence imaging for quantitative image analysis of photovoltaic modules
Winsvold, Jonas Rydtun (Master thesis, 2020)With a considerable demand for renewable energy where PV technology has a high potential for an increase in efficiency, there are continuously immense efforts to improve it. Electroluminescence is one of the promising ... -
Effect of Soiling on the Performance of Photovoltaic Modules in Kalkbult, South Africa
Øgaard, Mari Benedikte (Master thesis, 2016)Med høy solinnstråling, vidstrakte landområder som er lite utnyttet på grunn av tørt klima, og gode økonomiske og politiske forhold for investeringer i fornybar energi, har Sør-Afrika et stort potensiale for utnyttelse av ... -
Electromagnetic modelling of power umbilical systems
Hovde, Martin (Master thesis, 2017)In current carrying cables with multiple electrical conductors, there will be interactions between the conductors due to electromagnetic fields. Not all of these conductors are excited by an external voltage source, but ... -
En analyse av varmtvannssystemet på Stovnerskogen sykehjem
Johannessen, Erik Meland (Master thesis, 2018)Det er forventet at energibehovet for varmt tappevann vil stå for en betydelig andel av det totale energibehovet i fremtidige bygninger. I godt isolerte bygg står oppvarming av varmt tappevann for inntil 75 % av det totale ... -
The Influence of Fe on the Structure and Hydrogen Sorption Properties of Ti-V-Based Metal Hydrides
Nygård, Magnus Moe; Sørby, Magnus Helgerud; Grimenes, Arne Auen; Hauback, Bjørn (Peer reviewed; Journal article, 2020)Ti-V-based metal hydrides have decent overall performance as hydrogen storage materials, but V is expensive and it is therefore tempting to replace it by less expensive ferrovanadium containing about 20% Fe. In the present ... -
Load match study of photovoltaic production and charging demand of electric vehicles in a zero emission neighbourhood : case Campus Evenstad
Nes, Heidi (Master thesis, 2017)Campus Evenstad is a university campus and a pilot area in The Research Centre on Zero Emission Neighbourhoods in Smart Cities (FME ZEN). FME ZEN aims to optimize the energy management of energy production, energy demand ... -
Mechanical and electrochemical prelithiation of silicon nanoparticles in lithium-ion battery anodes
Hjellbrekke, Alise Johannessen (Master thesis, 2017)Silicon (Si) is one of the most promising anode materials for the next generation lithium ion batteries, as it can store up to ten times the capacity compared to the conventional graphite anode. However, with its alloying ... -
Monitoring of Building Attached Photovoltaics in Norway
Engh, Anne Marte Minge (Master thesis, 2016-12-15)Abstract In this thesis, the challenges associated with monitoring of BAPV systems in Norway are investigated. Monitoring of PV systems can give valuable information of the performance of the system and notify when failures ... -
Multiscale vibrational spectroscopy of pollen
Bağcıoğlu, Murat (PhD Thesis;2016:10, Doctoral thesis, 2020-11-19)Pollen has a vital role in the reproduction of flowering plants by producing genetically diverse offspring via pollination. Environmental effects have strong influence on reproductive structures of plants, including on ... -
Støyfiltrering av sanntidsmålinger fra norske automatiske nedbørstasjoner : en beskrivelse og vurdering av Meteorologisk Institutt sin nye korrigeringsalgoritme
Dramstad, Maylinn Cecilie (Master thesis, 2020)Det er flere ulike måter å måle nedbør på, både manuelle og automatiske metoder, og de ulike metodene benyttes på ulike målestasjoner. I Norge benyttes norske- og svenske målere på manuelle målestasjoner, mens Geonor T-200B ... -
