(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Landslide tsunamis and impulse waves are hazardous events with severe socioeconomic impacts. A long standing problem with simulations of these events is the generation stage, where landslides and water interact. Depth-averaged ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The effect of an external magnetic field on the formation of the wake in the potential distribution behind a dust grain is studied with self-consistent Particle-In-Cell numerical simulations. The collisionless plasma flow ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The charging of a sounding rocket in subsonic and supersonic plasma flows with external magnetic field is studied with numerical particle‐in‐cell (PIC) simulations. A weakly magnetized plasma regime is considered that ...
-
(Doctoral thesis / Doktoravhandling, 2021)Landslides can generate large tsunamis when falling into lakes and the sea. In order to protect coastal areas and communities we need to predict these events. Mathematical models have become a popular method for this task. ...

NUMERICAL SOLUTION OF THE THREE DIMENSIONAL BOUSSINESQ EQUATIONS FOR DISPERSIVE SURFACE WAVES PART 1 (Research report / Forskningsrapport, 1985)
-
(Master thesis / Masteroppgave, 2014)Oppgaven tar for seg den seismiske bølgeligningen i et og to lag med materialer ved hjelp av endelige differanser i tid, og ved bruk av elementmetoden for romlige koordinater. Oppgaven er delt i en serie prosjekter som tar ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Observations of wave propagation in landfast ice were obtained in Tempelfjorden, Svalbard during March 2015. Wave motion was measured near the ice edge using inertial motion units and consisted of a combination of swell ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)We provide some new local obstructions to approximating tropical curves in smooth tropical surfaces. These obstructions are based on a relation between tropical and complex intersection theories, which is also established ...
-
(Master thesis / Masteroppgave, 2012)Til enhver kvatratisk (reel eller kompleks) matrise A kan man tilordne dens eksponentialmatrise e^{At}. Eksponentialmatriser spiller en viktig rolle ved løsningen av enkelte differensialligninger og i mange andre anvendelser. ...
