Generalized Chessboard Structures Whose Effective Conductivities Are Integer Valued
(Journal article; Peer reviewed, 2012)We consider generalized chessboard structures where the local conductivity takes two values 𝑎� and 𝑏�. All integer combinations of 𝑎� and 𝑏� which make the components of effective conductivity matrix integer valued are ... -
Transport av betong i kaldt klima. Forstudie. Kartlegging av temperaturutvikling i betong på vei fra blandeverk til byggeplass
(SINTEF Notat;37, Research report, 2021)I denne forstudien har vi utført praktiske målinger på transport av fersk betong i kaldt klima. Vi har fokusert på transport med trommelbil, helikoptertobbe og betongpumpe. Målingene er analysert og vurdert ved bruk av ... -
3D graphene aerogel framework enwrapped LiFePO4 submicron-rods with improved lithium storage performance
(Journal article; Peer reviewed, 2019)The three-dimensional (3D) graphene aerogel (GA)-wrapped LiFePO4 submicron-rod composite (LFP@GA) has been prepared successfully through a solvothermal method followed with rapid freezedrying. Monodispersed LiFePO4 ... -
Crude oil migration in sea-ice: Laboratory studies of constraints on oil mobilization and seasonal evolution
(Journal article; Peer reviewed, 2019)Rising Arctic maritime activities and hydrocarbon development increase the risk of an oil spill in and under Arctic sea-ice. Oil spilled under growing sea ice would be encapsulated within the ice cover. During spring and ... -
The Entrainment and Migration of Crude Oil in Sea Ice, the Use of Vegetable Oil as a Substitute, and Other Lessons from Laboratory Experiments
(Peer reviewed; Journal article, 2017)Understanding the interaction between oil and sea ice is essential in the development of oil spill detection and response technology in the Arctic. Laboratory experiments were performed to examine oil migration in sea ice ... -
Reduction of commercial hematite pellet in isothermal fixed bed-experiments and numerical modelling
(Peer reviewed; Journal article, 2016)In the present work, fixed bed reduction experiments were conducted at 1173 K over a range of H2/CO ratios from 0.8 to 2.0 and subsequently modelled numerically. The model consists of two one-dimensional, isothermal and ... -
Finite element analysis of shear deformation in reinforced concrete shear-critical beams
(Journal article; Peer reviewed, 2017)The objective of this paper was to study the contribution of shear deformation in reinforced concrete (RC) shear-critical beams. A 2D concrete material model based on smeared fixed crack was presented and incorporated into ... -
Electrophoretically deposited carbon nanotube spectrally selective solar absorbers
(Peer reviewed; Journal article, 2016)Three types of carbon nanotubes(CNT) have been investigated regarding their suitability as spectrally selective solar thermal absorbers.The CNT coatings were electrophoretically deposited on aluminum substrates using ... -
Non-linear static behaviour of ancient free-standing stone columns
(Peer reviewed; Journal article, 2017)This work investigated the non-linear behaviour of ancient natural stone columns in the Mediterranean region made from multiple blocks or ‘drums’. A two-dimensional custom-made computational model based on the discrete-element ... -
Experimental and Micro-CT study on the Oil Distribution in laboratory grown Sea Ice
(Peer reviewed; Journal article, 2017)Increasing activities in Arctic waters bare a risk of oil spills under ice-covered conditions and afford sound understanding of the interplay between sea ice and oil. Towards better knowledge, this study focuses on X-ray- ... -
Field measurements on the behavior of brash ice
(Peer reviewed; Journal article, 2019)The behavior and properties of brash ice are important issues for the design of ice-going vessels. Heavy brash ice conditions may cause vessels to be dependent on ice-breaker assistance and time delays in the shipping ... -
In situ field measurements of the temporal evolution of low-frequency sea-ice dielectric properties in relation to temperature, salinity, and microstructure
(Peer reviewed; Journal article, 2016)The seasonal evolution of sea-ice microstructure controls key ice properties, including those governing ocean– atmosphere heat and gas exchange, remote-sensing signatures, and the role of the ice cover as a habitat. ... -
Effect of Oil Pollution and Ice Formation on Microbial Community of Seawater from Ofotfjorden, Norway
(Chapter, 2018)Oil spill in ice-covered waters can become entrapped in sea ice and may be subjected to biodegradation by sea ice microorganisms. The extent of the hydrocarbon biodegradation, and microorganisms involved in such process ... -

3D reconstruction of existing concrete bridges using optical methods
(Peer reviewed; Journal article, 2019)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
Axially Loaded RC Walls with Cutout Openings Strengthened with FRCM Composites
(Journal article; Peer reviewed, 2018)Abstract: Upgrading existing buildings to new functional requirements may require new openings that can weaken the structure, prompting the need for strengthening. In such cases traditional strengthening solutions, such ... -
Performance of RC Walls with Openings Strengthened by Fiber Reinforced Polymers: An Experimental and Theoretical Investigation
(Chapter, 2017)Redesigning buildings to improve their space efficiency and allow changes in use is often essential during their service lives to comply with shifts in living standards and functional demands. This may require the introduction ... -
