Marine icing observed on KV Nordkapp during a cold air outbreak with a developing polar low in the Barents sea.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06)
Marine icing is a phenomenon that may occur for temperatures below subfreezing where sea spray
either is lofted from the sea surface or being generated by waves interacting with a ship or a
structure. On a voyage from Tromsø to the waters east of Bjørnøya late February 1987, the
Norwegian Coast Guard vessel KV Nordkapp experienced heavy icing due to a polar low that raged
over these waters during ...
Finite element analysis of human femur bone
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-04)
An effort is made to analyse the stresses experienced by the human femur.
In order to achieve these results a CAD model was developed by using the
3-D scanning of generic human femur for an individual of 70 kg weight
(approx. averaged adult weight). The marrow cavity has been
approximated as a hollow cylinder. The FEM model was built using solid
tetrahedral element (20-noded 186 structural ...
Prediction of the long-term performance of green liquor dregs as a sealing layer to prevent the formation of acid mine drainage
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-08)
One of the mining industry's main concerns is the management of waste rock and tailings generated by sulfide ore extraction. Upon exposure of atmospheric oxygen, iron sulfides oxidize generating acidity. Infiltrating water form a metal-rich acidic leachate called acid mine drainage (AMD), that can cause serious environmental problems. Green liquor dregs (GLD) is a material that resists the passage ...
Ambient air quality and the effects of air pollutants on otolaryngology in Beijing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-09)
Abstract To investigate temporal patterns, pollution
concentrations and the health effects of air pollutants in
Beijing we carried out time-series analyses on daily concentrations
of ambient air pollutants and daily numbers of
outpatient visits for otolaryngology over 2 years (2011–
2012) to identify possible health effects of air pollutants.
The results showed that PM10 was the major air ...
Application of a 2-D approximation technique for solving stress analyses problem in FEM

Dynamic spare parts transportation model for Arctic production facility
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-14)
Timely delivery of the required spare parts plays an important role in meeting the
availability target and reducing the downtime of production facilities. Spare parts logistics is
affected in complex ways while operating in the Arctic, since the area is sparsely populated and
has insufficient infrastructure. It is also greatly affected by the distinctive operational
environment of the region, ...
Shipping oil from the Russian Arctic: Past experiences and future prospects
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06)
Transport of oil from Russian Arctic ports to Western markets was insignificant prior to 2002.
In 2002, there was a major surge, with 5 million tonnes delivered westwards through the
Barents Sea. By 2004, this had increased to 12 million tonnes. Since then, annual volumes
have been on levels between 9 and 15 million tonnes. In the near future, the flow of oil cargo
in the Arctic may rise ...
Evaluating Visual Saliency Algorithms: Past, Present and Future
(Tidsskriftartikkel; Journal article; Peer reviewed, 2015-09-01)
With the introduction of compressed sensing (CS) theory, investigation into exploiting sparseness and optimizing compressive sensing performance has ensued. Compressed sensing is highly applicable to images, which naturally have sparse representations. Improvements in the area of image denoising have resulted from the combination of highly-directional transforms with shrinkage and thresholding ...

Learning from experience
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-14)
The purpose of this study was to explore how pilots potentially learn from their and others‘ experience through post-flight debriefing. Through a case study of pilots who fly air ambulances, this article attempts to illustrate the importance of learning from experience (Bion 1962) among pilots in aviation.
