Modelling of creep compacting outcrop chalks injected with Ca-Mg-Na-Cl brines at reservoir conditions
(Peer reviewed; Journal article, 2019)Numerical and analytical 1D solutions are presented to interpret the link between geochemical alterations and creep compaction (compaction under constant effective stress) in chalk cores. Chemically reactive flow enhancing ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -
The Middle Jurassic to lowermost Cretaceous in the SW Barents Sea: Interplay between tectonics, coarse-grained sediment supply and organic matter preservation
(Peer reviewed; Journal article, 2020)Syn‐rift successions contain both prolific organic‐rich and coarse‐grained rocks, but these rocks are usually studied independently. Thus, the interplay among organic matter deposition, tectonics and sediment supply is not ... -
Will GPS Jammers Proliferate in the Smart City?
(Peer reviewed; Journal article, 2019)The Smart City will rely extensively on consented and unconsented information about people’s location and movements in order to fulfil its many ambitions. Utilising the Global Positioning System (GPS) is necessary and ... -
Accountability Requirements for the Cloud
(Chapter, 2017)In order to be responsible stewards of other people’s data, cloud providers must be accountable for their data handling practices. The potential long provider chains in cloud computing introduces additional accountability ... -
Some factors affecting the grades of technology students
(Peer reviewed; Journal article, 2017)In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to ... -
Immigrants in Norway: Resilience, challenges and vulnerabilities in times of COVID-19
(Peer reviewed; Journal article, 2022)Immigrants have been found to be disproportionately impacted during the COVID-19 pandemic across the world. Our study, exploring the experiences of immigrants in Norway during the pandemic, is based on interviews and focus ... -
Energy, exergy and environmental analysis of a novel combined system producing power, water and Hydrogen
(Peer reviewed; Journal article, 2017)During last years, absorption heat transformers have been used widely for boosting low-grade heat sources. In this paper, a novel multi-generation system including an open absorption heat transformer (OAHT), an organic ... -
Energy consumption for salmon slaughtering processes
(Chapter, 2017)Today’s slaughtering and processing method for Atlantic salmon (Salmo salar) using large refrigerated seawater (RSW) and buffer tanks before and during a stepwise processing regime has now reached its limits. To overcome ... -
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... -
Rayleigh and Wood anomalies in the diffraction of acoustic waves from the periodically corrugated surface of an elastic medium
(Peer reviewed; Journal article, 2016)By the use of the Rayleigh method we have calculated the angular dependence of the reflectivity and the efficiencies of several other diffracted orders when the periodically corrugated surface of an isotropic elastic medium ... -
Energi til norsk veksthusnæring - bruk av naturgass som energibærer og CO2-kilde
(Bioforsk Rapport;, Research report, 2006)Norsk gartnerinæring bruker anslagsvis 1 000 GWh per år. Planteproduksjon i veksthus her i landet har stort behov for elektrisk energi og avhengig av kultur og produksjonsopplegg varierer andelen elektrisk energi fra 50-80 ... -
Testing the robustness of optimal access vessel fleet selection for operation and maintenance of offshore wind farms
(Peer reviewed; Journal article, 2017)Optimising the operation and maintenance (O&M) and logistics strategy of offshore wind farms implies the decision problem of selecting the vessel fleet for O&M. Different strategic decision support tools can be applied to ... -
Damping estimation of large wind-sensitive structures
(Peer reviewed; Journal article, 2017)The adequacy of two identification techniques to accurately estimate the modal damping ratios (MDRs) from ambient vibration records is assessed for long-span suspension bridges with eigen frequencies close to or below 0.1 ... -
The Effect of Different Drilling Fluids on Mechanical Friction
(Peer reviewed; Journal article, 2017)A very important aspect in highly inclined wellbores is the mechanical friction. For extended reach drilling (ERD) and through tubing extended reach drilling (TTERD) this can be a limiting factor. Friction caused by the ... -
Measurements of Surface-Layer Turbulence in a Wide Norwegian Fjord Using Synchronized Long-Range Doppler Wind Lidars
(Peer reviewed; Journal article, 2017)Three synchronized pulsed Doppler wind lidars were deployed from May 2016 to June 2016 on the shores of a wide Norwegian fjord called Bjørnafjord to study the wind characteristics at the proposed location of a planned ... -
Development of Construction Material Using Wastewater: An Application of Circular Economy for Mass Production of Bricks
(Peer reviewed; Journal article, 2022)Water is one of the necessary ingredients for construction materials. Billions of gallons of clean water are wasted during the development of fired clay bricks. Similarly, the waste of clean water is a global issue. In ... -
