1.80–1.75 Ga granite suites in the west Troms Basement Complex, northern Norway: Palaeoproterozoic magma emplacement during advancing accretionary orogeny, from field observations
(Peer reviewed; Journal article, 2022)The Ersfjord Granite is part of a suite of c.1.80–1.75 Ga syeno-granites in the West Troms Basement Complex, northern Norway, presumed to belong to the Transscandinavian Igneous Belt (TIB-1) in the Fennoscandian Shield. ... -
100 key questions to guide hydropeaking research
(Peer reviewed; Journal article, 2023)As the share of renewable energy grows worldwide, flexible energy production from peak-operating hydropower and the phenomenon of hydropeaking have received increasing attention. In this study, we collected open research ... -
1453. Comparison of the ride performance of an integrated suspension model
(Journal article; Peer reviewed, 2014)Vehicle suspension is one of the important components to reduce vibration from the road. The vehicle seat suspension acts as another component to provide ride comfort, especially to reduce driver fatigues for long hour’s ... -
1D and 3D Petroleum System Modelling of the Songo Songo source rocks, southern coastal offshore Tanzania.
(Master thesis, 2015)3D petroleum system modelling of the Songo Songo area, located southern coastal offshore Tanzania, has been constructed with PetroMod software using surfaces interpreted from 2D seismic lines. 1D modelling, in combination ... -
1D modelling of membrane-assisted chemical looping reforming
(Journal article; Peer reviewed, 2017)Membrane-assisted chemical looping reforming (MA-CLR) has been proposed as an alternative to the conventional CLR technology. In this work, a non-isothermal 1D model is used to simulate the MA-CLR fuel reactor. The effect ... -
2-D and 2.5-D Multi-scale Full-Waveform Inversion in frequency domain for high-resolution P-wave velocity (Vp) and quality factor (Q) models at Sleipner field.
(Master thesis, 2018)In this work, we have applied a multi-scale discretized Full-Waveform Inversion in frequency-space domain considering both the 2-D and 3-D viscoacoustic wave equation for deriving P-wave velocity (Vp) and quality factor ... -
2-D Finite Difference Modelling and Analysis of Shallow Gas Leakage Scenarios, Using Time-Lapse Refraction
(Master thesis, 2013)4D seismic is a relatively new technology used aggressively in the oil industry, over the years it has proved its potential. However, there is a need for development of new techniques with high precision that enable the ... -
25 years of field exposure of pre-cracked concrete beams; combined impact of spacers and cracks on reinforcement corrosion
(Peer reviewed; Journal article, 2021)The state of corrosion of three pre-cracked concrete beams was investigated after 25 years of marine exposure (atmospheric, tidal and submerged). The influence of inadequate plastic spacers was found to overrule the possible ... -
2D and 3D Modeling Comparison
(Bachelor thesis, 2010)Many inventors and companies still use 2D drawings and are starting to realize a 3D design because 3D modeling can save time and money. In this project I am going to compare 2D and 3D drawings and modeling. 2D modeling ... -
