How particle size affects the melting of snow
(Master thesis, 2021)Noreg har lange tradisjonar for skigåing, og når vintrane blir varmare aukar behovet for ei påliteleg kjelde for snø. Byar nært kysten er spesielt utsett når det er små forandringar som skal til før temperaturen går frå ... -
How severe space weather can disrupt global supply chains
(Journal article; Peer reviewed, 2014)Coronal mass ejections (CMEs) strong enough to create electromagnetic effects at latitudes below the auroral oval are frequent events that could soon have substantial impacts on electrical grids. Modern society’s heavy ... -

(Master thesis, 2021)Abstract will be available on 2022-10-01 -
How to avoid gas supersaturation in the river downstream a hydropower plant
(Master thesis, 2020)Gassovermetning i vannkraftverk er en lite kjent, men veldig alvorlig tilstand som har påvirket biologisk mangfold negativt i flere vassdrag i Norge. Det er kjent at 10 kraftverk har hatt redusert biologisk mangfold på ... -
How to Avoid Total Dissolved Gas Supersaturation in Water from Hydropower Plants by Employing Ultrasound
(Peer reviewed; Journal article, 2020)In Norway, more than 10 hydropower plants are known to have caused biologically relevant levels of total dissolved gas supersaturation in the rivers downstream power plants. This phenomenon is causing fish kills due to gas ... -
How to quantify biodiversity footprints of consumption? A review of multi-regional input–output analysis and life cycle assessment
(Journal article; Peer reviewed, 2018)Reducing direct pressures on biodiversity will only be possible once the consumption drivers behind them are identified. Target 4 of the Convention on Biological Diversity highlights the importance of moving towards ... -
Höchtemperatur-Wärmepumpen mit natürlichen Kältemitteln : Fallstudien zur HTWP-Integration für industrielle Kälte- und Prozessheisswasserherstellung
(Chapter, 2021)Thermische Prozesse in der Nahrungsmittelindustrie, wie z. B. Molkereien sind oftmals eine Kombination aus Erwärmung und Abkühlung eines Produktes. Prozesskühlung wird dabei meistens mittels einer Wärmepumpe erzielt, wobei ... -
Human dimensions of natural resource management for the Vosso wild salmon population: A systems thinking approach
(Master thesis, 2011)Vosso, the second-largest watershed in Norway, was considered special as it produced some of the biggest salmon in the country. This salmon had economic, cultural as well as ecological importance. Due to its diversity, it ... -
Hybrid artificial intelligence model for prediction of heating energy use
(Peer reviewed; Journal article, 2021)Currently, in the building sector there is an increase in energy use due to the increased demand for indoor thermal comfort. Proper energy planning based on a real measurement data is a necessity. In this study, we developed ... -
A Hybrid Data-Driven Metaheuristic Framework to Optimize Strain of Lattice Structures Proceeded by Additive Manufacturing
(Peer reviewed; Journal article, 2023)This research is centered on optimizing the mechanical properties of additively manufactured (AM) lattice structures via strain optimization by controlling different design and process parameters such as stress, unit cell ... -
Hybrid Flux Splitting Schemes for Numerical Resolution of Two-Phase Flows
(Doctoral thesis, 2003)This thesis deals with the construction of numerical schemes for approximating solutions to a hyperbolix two-phase flow model. Numerical schemes for hyperbolic models are commonly divided in two main classes: Flux Vector ... -
Hybrid life cycle assessment at the neighbourhood scale: The case of Ydalir, Norway
(Peer reviewed; Journal article, 2022)The focus of this study is Ydalir, a neighbourhood in Norway currently in the early planning stages. Ydalir aims to produce its energy locally based on renewable sources, has passive house standards or higher for all its ... -
Hybrid life cycle assessment of steel production with carbon capture and storage
(Master thesis, 2013)Among several Green house gases, CO2 is a main contributor and accounts for about 60% of the greenhouse effect because of its huge emission amount. The iron and steel sector has showed one of the largest energy intensity ... -
Hybrid Life Cycle Assessment of Wood-based Biofuel Production and Consumption Scenarios in Norway
(Master thesis, 2008)An increasingly urgent need to develop alternatives to fossil fuels in road trans- portation stems from both the need to combat climate change and the need to prepare for a transition beyond peak oil. Biofuels can be part ... -
