(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)This article is devoted to the extension of the theory of rough paths in the context of Volterra equations with possibly singular kernels. We begin to describe a class of two parameter functions defined on the simplex ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)We extend the recently developed rough path theory for Volterra equations from [12] to the case of more rough noise and/or more singular Volterra kernels. It was already observed in [12] that the Volterra rough path ...
-
(Master thesis / Masteroppgave, 2010)Long, non-dispersive coastal wind-generated internal waves in the Hardangerfjord is investigated based on hydrographic data at the coast and current and temperature measurements in the fjord. The aim of the present work ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The aim was to evaluate the performance of different microsampling materials in LC–MS-based protein analysis. The evaluated materials were the Volumetric Absorptive MicroSampling (VAMS) device, the pure cellulose sampling ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Understanding the approach to faulting in continental rocks is critical for identifying processes leading to fracturing in geomaterials and the preparation process of large earthquakes. In situ dynamic X-ray imaging and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)To examine the impact of preexisting weaknesses on fracture coalescence during volcanic edifice deformation, we triaxially compressed Mount Etna basalt while acquiring in situ dynamic X‐ray microtomograms and calculated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A positive fluorine-18 labelled 2-deoxy-2-fluoroglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) has been associated with more aggressive disease and less differentiated neuroendocrine neoplasms ...
-
(Master thesis / Hovedoppgave, 2005)This thesis looks into features of the volume flux in the narrow Drøbak strait, and water level changes in the inner Oslofjord. Earlier measurements suggest that the volum flux in the east course of the strait, calculated ...
-
(Master thesis / Hovedoppgave, 2004)In our modern society we are overwhelmed by information. Supercomputers all over the world are generating data sets containing terabytes of numerical data. In the years ahead the greatest challenge to the scientifc community ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Every real algebraic variety determines a Voronoi decomposition of its ambient Euclidean space. Each Voronoi cell is a convex semialgebraic set in the normal space of the variety at a point. We compute the algebraic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Solar “magnetic tornadoes” are produced by rotating magnetic field structures that extend from the upper convection zone and the photosphere to the corona of the Sun. Recent studies show that these kinds of rotating features ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The study of vortex flows around solid obstacles is of considerable interest from both a theoretical and practical perspective. One geometry that has attracted renewed attention recently is that of vortex flows past a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Vortex flows, related to solar convective turbulent dynamics at granular scales and their interplay with magnetic fields within intergranular lanes, occur abundantly on the solar surface and in the atmosphere above. Their ...
-
(Master thesis / Hovedoppgave, 1998)Chern-Simons-Ginzburg-Landau (CSGL) theory is an attempt of a phenomenological description of the fractional quantum Hall effect. The CSGL theory is studied mainly without considering the direct applications of the results. ...
-
(Doctoral thesis / Doktoravhandling, 2022)Coherent swirling bodies of water; mesoscale (10-100 km) vortices, are an essential part of the general ocean circulation. Mesoscale vortices are abundant everywhere in the World Ocean and are vital in upholding equilibrium ...
-
(Master thesis / Masteroppgave, 2015)The amount of data in today's digital world is growing day by day. Visualization is considered as the best form of communication because the human brain perceives it much faster than the text data that comprises with ...
-
(Master thesis / Masteroppgave, 2016)3D models created in Computer Aided Design (CAD) software are ubiquitous in the manufacturing industry. Preparing for analysis on them has typically been a very time-consuming process, and isogeometric analysis was therefore ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Purpose To establish whether reliable voxel-wise assessment of perfusion in cerebral white matter (WM) is possible using arterial spin labeling (ASL) at 3T in a cohort of healthy subjects. Materials and Methods Pseudo-continuous ...
-
(Master thesis / Hovedoppgave, 2003)This thesis deals with volume rendering in OpenGL and looks at the different areas at which 3D modeling and visualization is used. The thesis focuses on voxel rendering, its advantages and drawbacks, and also the implementation ...
