Effect of Confinement with FRCM Composites on Damaged Concrete Cylinders
(Journal article; Peer reviewed, 2017)Confinement of axially loaded concrete members in existing structures is required when a change in use is expected or when there is a need to upgrade the structure to meet current design standards. In addition, after unusual ... -
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 ... -
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 ... -
Evaluation of global ice load impacts based on real-time monitoring of ship motions
(Peer reviewed; Journal article, 2013) -
Examination of Sea Ice Cover in Norwegian Fjords
(Lecture, 2017)Presented are two steps being taken to examine sea ice coverage in Norwegian fjords as part of a larger study to improve our understanding of ice formation and breakup processes in these regions and implications for oil ... -
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- ... -
Experimental study on shear deformation of reinforced concrete beams using digital image correlation
(Journal article; Peer reviewed, 2019)This paper presents an experimental program aimed at providing reliable and comprehensive experimental data for assessing the available models of predicting the shear deformation of diagonally-cracked reinforced concrete ... -
Failure tests on concrete bridges: Have we learnt the lessons?
(Journal article; Peer reviewed, 2017)Full-scale failure tests of bridges are important for improving understanding of bridges’ behaviour and refining assessment methods. However, such experiments are challenging, often expensive, and thus rare. This paper ... -
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 ... -
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 ... -
Finite element simulation of punch through test using a continuous surface cap model
(Peer reviewed; Journal article, 2015)An attempt has been made to calibrate the material model parameters of the continuous surface cap model with data from punch through tests performed in the Northern Gulf of Bothnia. An axisymmetric finite element model has ... -
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 ... -
Heat Transfer in a Bed of Dry Iron Ore Pellets
(Peer reviewed; Journal article, 2013) -
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. ... -
Laboratory In-situ Burns of Oil on Ice
(Chapter, 2018)Oil spills in ice-covered waters pose unique challenges to remediation activities. In-situ burning is a potential remediation technique that has shown promising efficiency in earlier trials. An element of arctic in-situ ... -
