Sea-spray measurement tools and technique employed in marine icing field expeditions: A critical literature review and assessment using CFD simulations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)Sea-spray icing resulting from sea spray droplets accreting on exposed surfaces poses a significant safety concern for vessels and marine structures operating in cold climate regions. One of the key parameters determining the amount of ice accretion is the quantity of incoming sea spray, which eventually comes in contact with the structure in the presence of brine film freezing temperature. Hence, ... -

Seasonal and Spatial Variability of Atmospheric Emissions from Shipping along the Northern Sea Route
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-25)Large seasonal and spatial variabilities in Arctic shipping and its associated emissions are expected in the future, due to continuous sea ice decline. This study collected ship traffic data and the associated emissions of carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM), and black carbon (BC) along the Northern Sea Route (NSR) in 2013. The aim is to analyze ... -
Securitising the Future: Dystopian Migration Discourses in Poland and the Czech Republic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-09)This paper presents findings of a comparative study carried out in Poland and the Czech Republic, which analysed the societal attitudes towards migration and migrants in Europe. Our research shows that the reaction to migration in Poland and the Czech Republic constitutes a reversed (bottom up) securitisation. Moreover, contrary to the majority of security challenges where the immediate threats are ... -
Security and policing in Rio de Janeiro. An ethnography of the pacifying police units
(Master thesis; Mastergradsoppgave, 2016-12-15)In this thesis I address the challenges of Rio de Janeiro's ongoing public security reform, implemented through the establishment of the Pacifying Police Units (UPPs) in several of the city's favelas since 2009. I suggest that in order to address this problem, it is necessary to understand both the institutional and political context and conditions that the reform is set within, as well as the ... -
Security of Supply: A National or European Competence?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-16)Security of supply refers to governmental policies that aim to secure the availability of critical products at all times. The COVID-19 pandemic brought to fore the importance of such policies, as suddenly there was an overwhelming need for critical medical supplies that the markets were not able to fulfil. Following the pandemic, the EU has started to construct its own security of supply policy, ... -
Segmentation of Polar Mesospheric Summer Echoes using Fully Convolutional Network
(Master thesis; Mastergradsoppgave, 2023-04-26)Polar Mesospheric Summer Echoes (PMSE) are strong coherent radar echoes that occur in the 80 to 90 km altitude range of the mesosphere during the Arctic summer months. These echoes are of significant interest to the space physics community as they provide insight into changes that occur in the atmosphere. To better understand these changes, large datasets of PMSE echoes need to be analysed. In ... -
