(Peer reviewed; Journal article, 2018)In order to investigate the three-dimensional flow around free-spanning, tandem marine pipelines, Large Eddy Simulations (LES) with Smagorinsky subgrid scale model are performed using the open-source code OpenFOAM. Two ... -
Residual stress estimation in defect assessment procedures at weld toe and away locations on girth welds: Review of key parameters
(Peer reviewed; Journal article, 2020)The distribution of residual stresses in welded joints plays an important role within the fracture evaluation guidelines recommended in structural integrity assessment codes such as BS7910, API 579 RP-1/ASME FFS-1 and R6. ... -
Ad Hoc Table Retrieval using Semantic Similarity
(Chapter, 2018)We introduce and address the problem of ad hoc table retrieval: answering a keyword query with a ranked list of tables. This task is not only interesting on its own account, but is also being used as a core component in ... -
Map-based interfaces for common operational picture
(Chapter, 2020)Common operationalpicture (COP) map-based interfacesdisplay operational information to support integrationofemergency responders. Such interfacesintegrate different subsystems and present the resulting information into an ... -
Game Theoretic Analysis of Clickbait or Fake News and Real News
(Peer reviewed; Journal article, 2020)A decision and game theoretic model is developed for how one and two news organisations strike balances between producing clickbait or fake news, and real news. Each news organisation seeks to attract gullible consumers ... -
Metoder brukt for å forhindre svart økonomi og arbeidslivskriminalitet i offentlige anskaffelser innen bygg og anlegg i Finland, Sverige og Norge
(Bachelor thesis, 2022)Finland Sweden and Norway lose out on a lot of potential tax money due to the shadow economy in the construction industry. Workers employed within companies such as these work with bad working conditions and lose the right ... -
Technical and Economic Feasibility Analysis of a Conceptual Subsea Freight Glider for CO2 Transportation
(Peer reviewed; Journal article, 2022-08)This study analyses the technical and economic aspects of a novel subsea freight glider (SFG). The SFG is an excellent replacement for tanker ships and submarine pipelines transporting liquefied CO2. The main aim of the ... -
