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 ... -
Laboratory studies of oil encapsulation under Arctic Conditions
(Peer reviewed; Journal article, 2013) -
Laboratory testing of compressive and tensile strenght on level ice and ridged ice from Svalbard region
(Peer reviewed; Journal article, 2013) -
Local and global behavior of walls with cut-out openings in multi-story reinforced concrete buildings
(Journal article; Peer reviewed, 2019)This paper presents the finite element analysis (FEA) results of a multi-story reinforced concrete (RC) building having precast and cast-in-place load bearing walls. Door-type cut-out openings (height: 2.1 m, width: 0.9–4.4 ... -
Measurements to Estimate the Downward Heat Flux from a Burning Oil Pool
(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 in-situ burning ... -
Morphologies of ridges surveyed off Svalbard and in Fram strait, 2011 and 2012 field expeditions
(Peer reviewed; Journal article, 2013) -
Morphology, internal structure and formation of ice ridges in the sea around Svalbard
(Journal article; Peer reviewed, 2018)The results from 3 years of comprehensive field investigations on first-year ice ridges in the Arctic are presented in this paper. The scopes of these investigations were to fill existing knowledge gaps on ice ridges, gain ... -
MOSIDEO/CIRFA Experiments on Behavior and Detection of Oil in Ice
(Lecture, 2017)- Preparedness and response to oil in sea ice-covered waters - When does oil melt out of the ice - When can oil be detected with remote sensing techniques? -
Mosideo/cirfa tank experiments on behavior and detection of oil in ice
(Peer reviewed; Journal article, 2019)In the Arctic, presence of sea ice presents a challenge to safe and sustainable operations. To optimize planning and minimize impact of inadvertent oil spills, oil-in-ice experiments were performed at the HSVA Arctic ... -
