NUMERICAL SOLUTION OF THE THREE DIMENSIONAL BOUSSINESQ EQUATIONS FOR DISPERSIVE SURFACE WAVES PART 1 (Research report / Forskningsrapport, 1985)
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)We investigate the numerical stability of time-dependent coupled-cluster theory for many-electron dynamics in intense laser pulses, comparing two coupled-cluster formulations with full configuration interaction theory. Our ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)With reference to laboratory Q-machine studies we analyze the dynamics of a plasma diode under external forcing. Assuming a strong axial magnetic field, the problem is analyzed in one spatial dimension by a particle-in-cell ...
-
(Doctoral thesis / Doktoravhandling, 2024)Did you know that in the vacuum of space, there is no vacuum? In fact, most of space is filled with charged particles in a plasma state. Close to Earth, Geomagnetic phenomena, space weather, and radio interference such as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We present a numerical study disclosing non-linear effects and hysteresis loops for a swept bias Langmuir probe. A full kinetic particle in cell (PIC) model has been used to study the temporal sheath effects and the probe ...
-
(Master thesis / Masteroppgave, 2013)Packing of equally sized spheres is an extensive field of research, and the applications range from granular media on the macroscopic scale, to theories of liquids and gases. This thesis presents results from numerical ...
-
(Master thesis / Masteroppgave, 2009)In this project I address the questions of how the frictional force depend on the sliding velocity. Can asperity creep give a velocity weakening effect on the dynamic coefficient of friction for low sliding velocities, and ...

-
(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 ...
-
(Master thesis / Hovedoppgave, 1996)Sammendrag Oppgaven innledes med en innføring i noen grunnleggende begreper innen akustikken,og nevner noen fundamentale relasjoner og karakteristiske fenomener.En gjennomgang av publiserte eksempler på bruk av matematisk ...

Numerisk Løsning av Den Todimensjonale Akustiske Bølgelikningen for Marin Seismikk : Mot ghostfri marin seismikkRestricted Access (Master thesis / Masteroppgave, 2012)I marinseismiske undersøkelser benyttes luftkanoner til å produsere lydbølger som gjennomtrenger jordskorpen under havbunn. En luftkanon er en sylinder hvor store menger luft under høyt trykk blir lagret og sluppet ut over ...
-
(Master thesis / Masteroppgave, 2020)Kvikkleire kan påtreffes under marin grense i Norge, Sverige, Finland, Russland, Canada og Alaska. Den vanligste utløsende årsaken til kvikkleireskred de siste tiårene er menneskelig aktivitet, men kvikkleireskred utløses ...
-
(Master thesis / Masteroppgave, 2013)Målet med dette arbeidet er å finne ut om moderne numeriske atmosfæremodeller klarer å varsle underkjølt skyvann og underkjølt regn. I den mye brukte atmosfæremodellen WRF (Weather Research and Forcasting [Skamarock et al. ...
-
(Master thesis / Masteroppgave, 2015)Studiet undersøker muligheten for å bruke Steamline Upwind/Petrov Galerkin (SUPG) og Discontinuous Galerkin (DG) i adveksjons-dominert skalar-blanding med høyt Schmidt-tall. Forenklede tester viste at DUPG og DG gir dårlig ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Background Traditionally, drug prescription and follow up have been the sole responsibility of physicians. However, interprofessional medication reviews (IMRs) have been developed to prevent drug discrepancies ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Aim The aim of this study was to explore bachelor-level nursing students’ experiences with concept cartoons as an active learning strategy and formative assessment to develop conceptual understanding in anatomy and ...
