(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract It goes back to Ahlfors that a real algebraic curve admits a real-fibered morphism to the projective line if and only if the real part of the curve disconnects its complex part. Inspired by this result, we are ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)This paper considers data-based real-time adaptive Fault Detection (FD) in Grid-connected PV (GPV) systems under Power Point Tracking (PPT) modes during large variations. Faults under PPT modes remain undetected for longer ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Thermal protection in marine electrical propulsion motors is commonly implemented by installing temperature sensors on the windings of the motor. An alarm is issued once the temperature reaches the alarm limit, while the ...

(Master thesis / Masteroppgave, 2018)Recommender systems are algorithms that suggest content or products to users on the internet. These are becoming ever more important due to the massive growth of content on popular web sites, yet their design is often only ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Recovering a signal (function) from finitely many binary or Fourier samples is one of the core problems in modern imaging, and by now there exist a plethora of methods for recovering a signal from such samples. Examples ...

(Master thesis / Masteroppgave, 2021)For electric propulsion motors installed on marine vessels, the prevention of overheating is usually based on resistor temperature detector sensors. The monitoring system raises an alarm if the detected temperatures reach ...

(Master thesis / Masteroppgave, 2010)Abstract Stochastic optimization using the stochastic Bellman equation, and probabilities approximated by way of Monte-Carlo, is a fairly unexplored field -- especially when the probabilities are affected by the controls. ...

(Master thesis / Masteroppgave, 2013)The European Trading Scheme (ETS) has been implemented as a way of reducing emissions of greenhouse gasses. In this scheme European Union emission allowances (EUAs) are traded during the so called trading period. In the ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In this paper, we introduce a sublinear conditional expectation with respect to a family of possibly nondominated probability measures on a progressively enlarged filtration. In this way, we extend the classic reduced-form ...
