(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Data simulation is fundamental for machine learning and causal inference, as it allows exploration of scenarios and assessment of methods in settings with full control of ground truth. Directed acyclic graphs (DAGs) are ...
-
(Master thesis / Masteroppgave, 2009)New challenges within statistical sciences have arisen with the explosive growth of information. Classical methods are not designed for these kinds of problems and may not be possible to use or may not behave as expected. ...
-
(Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2023)Battery systems are increasingly being used for powering ocean going ships, and the number of fully electric or hybrid ships relying on battery power for propulsion and maneuvering is growing. In order to ensure the safety ...

-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2022)This paper aims to propose an efficient machine learning framework for maritime big data and use it to train a random forest model to estimate ships’ propulsion power based on ship operation data. The comprehensive data ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)In this paper we investigate a local surface approximation, the Weighted Quasi Interpolant Spline Approximation (wQISA), specifically designed for large and noisy point clouds. We briefly describe the properties of the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The number of fully electric or hybrid ships relying on battery power for propulsion and maneuvering is growing. In order to ensure the safety of these ships, it is important to monitor the capacity that can be ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Battery systems are becoming an increasingly attractive alternative for powering ocean going ships, and the number of fully electric or hybrid ships relying on battery power for propulsion and manoeuvring is growing. In ...

-
(Master thesis / Masteroppgave, 2018)Applying the computational fluid dynamics software openFoam, we study dead water resistance on a barge. Dead water resistance is the extra drag due to internal waves in the interface between salt water and fresh water. For ...

(Research report / Forskningsrapport, 1999)
-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2018)We identify a number of decidable and undecidable fragments of first-order concatenation theory. We also give a purely universal axiomatization which is complete for the fragments we identify. Furthermore, we prove some ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We present a case of seismic reservoir characterization within a multi-source depositional setting. To resolve issues of non-uniqueness between intrinsic reservoir properties and the seismic data, we use a probabilistic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Changes in the body condition of Antarctic minke whales ( Balaenoptera bonaerensis ) have been investigated in a number of studies, but remain contested. Here we provide a new analysis of body condition measurements, ...

(Master thesis / Masteroppgave, 2022)This thesis is concerned with the module of Kähler differentials of an affine scheme and its primary decomposition. For a smooth scheme, these are the local building blocks of the cotangent bundle. Each inclusion of a ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The analysis of microcirculation images has the potential to reveal early signs of life-threatening diseases such as sepsis. Quantifying the capillary density and the capillary distribution in microcirculation images can ...
