(Master thesis / Masteroppgave, 2023)Vortexes are a major part of turbulence studies, and have dominating effect on aerodynamics. Vortex generators have been used for a long time on air-crafts, to delay flow separation and increase performance. In this study, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We present a collection of research questions on cubic surfaces in 3-space. These questions inspired the present collection of papers. This article serves as the introduction to the issue. The number of questions is meant ...

(Master thesis / Masteroppgave, 2022)Sequential Monte Carlo methods are often used for inference in state space models that are nonlinear and non-Gaussian. Inference about the latent variables of a state space model can be performed in an online setting by ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)A cohomology class of a smooth complex variety of dimension n has coniveau at least c if it vanishes in the complement of a closed subvariety of codimension at least c, and it has strong coniveau at least c if it comes by ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Let ℓ be a prime and q=pν, where p is a prime different from ℓ. We show that the ℓ–completion of the nth stable homotopy group of spheres is a summand of the ℓ–completion of the (n,0) motivic stable homotopy group of spheres ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Two-phase oil and gas flow were simulated in an entirely eccentric annulus and compared with experimental data at horizontal, 4, 10, and 90° inclination. The gas-phase was sulphur hexafluoride and the liquid phase a mixture ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Co-current two-phase simulations of gas-liquid flow with mixture velocities from 1.2 to 4.2 m/s were run in a partially eccentric annulus and compared with entirely eccentric and concentric experimental data collected at ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 1999)We outline the link between automorphisms (symmetries) of manifolds and algebraic K-theory of spaces. Then we discuss recent two-primary calculations for the algebraic K-theory of a point, and obtain a two-primary description ...
