Marine Lobe Pumps: A CFD Study on Performance and Impact on Aquatic Life
(Master thesis, 2023)I denne masteroppgaven ble fluiddynamikken i en tre-lobet pumpe med episykloidale lober undersøkt ved hjelp av numeriske strømningsberegninger. Studien vektlegger vurderingen av pumpens mekaniske interaksjoner med akvatisk ... -
The MarINvaders Toolkit
(Journal article; Peer reviewed, 2021)The introduction and establishment of alien (non-native) species to foreign ecosystems is a key threat for marine biodiversity (Katsanevakis et al., 2014; Molnar et al., 2008; Seebens et al., 2017). Ecosystem pressures ... -
MarINvaders: A web toolkit of marine species for use in environmental assessments
(Peer reviewed; Journal article, 2023)Invasive species are the second most important reason for species extinction since 1500 ad. In addition, these invasive species can cause vast economic loss. In marine ecoregions, alien species introductions are increasing, ... -
Maritime Shipping and Emissions: A three-layered, damage based approach
(Journal article; Peer reviewed, 2015-12-01)Policy emphasis in ship design must be shifted away from global and idealized towards regional based and realistic vessel operating conditions. The present approach to reducing shipping emissions through technical standards ... -
Mass balance model for Hammerfest LNG plant Snøhvit
(Master thesis, 2007)The goal of the task is to develop and test a mass balance model for the entire Snøhvit facility which makes it possible to balance all streams inn and out. The model is implemented in an excel sheet. Also production rate ... -
Mass transfer modelling of natural gas dehydration for the Gas-2-Pipe process
(Master thesis, 2020)Verden beveger seg mot økonomisk levedyktige investeringer. Et av hovedmålene med dagens teknologiske fremskritt er å skape et økonomisk gjennomførbart produkt og kutte ned menneskekraften ved å gjøre det beste ut av den ... -
Mateerial System Analysis of five battery-related raw materials: Cobalt, Lithium, Manganese, Natural Graphite, Nickel
(Research report, 2020)The transition to a climate-neutrality is expected to boost the demand for batteries in the coming years. If the EU wants to be competitive in the global market of battery manufacturing it has to ensure a sustainable, ... -

Material Stock and Embodied Greenhouse Gas Emissions of Global and Urban Road Pavement
(Peer reviewed; Journal article, 2022)Roads play a key role in movements of goods and people but require large amounts of materials emitting greenhouse gases to be produced. This study assesses the global road material stock and the emissions associated with ... -
Material system analysis: A novel multilayer system approach to correlate EU flows and stocks of Li-ion batteries and their raw materials
(Peer reviewed; Journal article, 2022)Lithium-ion batteries (LIBs) will play a crucial role in achieving decarbonization and reducing greenhouse gases. If the EU wants to be competitive in the global market of LIBs, it has to ensure a sustainable and secure ... -
Materials for Proton Exchange Membrane water electrolyzer bipolar plates
(Journal article; Peer reviewed, 2017)Titanium based BiPolar Plates (BPPs) are commonly used in Proton Exchange Membrane Water Electrolyzers (PEMWEs) today as they can withstand the harsh operating conditions experienced inside an operating PEM water electrolyzer. ... -
Mathematical and data-driven modelling of case ventilation system
(Master thesis, 2022)Energieffektivisering av bygninger har blitt et stadig viktigere fagområde ettersom at klimabevissthet og energiforbruk har fått mer oppmerksomhet gjennom tidene. En måte å øke energieffektviteten til bygninger er ved å ... -
