Development of robust and efficient solution strategies for coupled problems
(Doctoral thesis, 2022-10-10)Det er mange modeller i moderne vitenskap hvor sammenkoblingen mellom forskjellige fysiske prosesser er svært viktig. Disse finner man for eksempel i forbindelse med lagring av karbondioksid i undervannsreservoarer, flyt ... -
Diagnostic drama. Use of ICDAS II and fluorescence-based intraoral camera in early occlusal caries detection: A clinical study
(Journal article; Peer reviewed, 2020)Background: Early diagnosis of occlusal caries is of paramount importance for a minimally invasive approach in dentistry. The aim of the present in vivo clinical prospective study was to compare the diagnostic outcomes of ... -
Diagram spaces and multiplicative structures
(Doctoral thesis, 2022-01-14)This thesis explores diagrammatic E_n structures as models for E_n spaces. Paper A: Braided injections and double loop spaces. (Christian Schlichtkrull and Mirjam Solberg.) We consider a framework for representing ... -
Didaktiske escape room i matematiske læringsaktiviteter
(Master thesis, 2024-06-03)Samfunnet endrer seg raskt og samfunnet vil stille store krav til fremtidens borgere. Blant annet kommunikasjon og samarbeid vil i fremtiden stå som ferdigheter som i stadig større grad vil bli utfordret. Undervisningen ... -
Didaktiske tilnærminger til den deriverte i læremidler for matematikk 1T
(Master thesis, 2024-06-03)I forbindelse med fagfornyelsen LK20, har dybdelæring blitt trukket fram som et sentralt element i norsk skole. I matematikk innebærer dette blant annet å ha en god begrepsmessig forståelse. Denne studien undersøker hvordan ... -

Different aspects of the hodograph transform and Riemann invariants for the shallow water equations
(Master thesis, 2018-12-15)The aim of this work is to visualize irrotational long wave on a sloping beach by following the approach of Carrier and Greenspan [5]. We first derive the non-linear shallow-water equations for sloping beach and then find ... -
Differentiability of Products of Formal Power Series

Dimensional reduction of a fractured medium for a polymer EOR model
(Journal article; Peer reviewed, 2021)Dimensional reduction strategy is an effective approach to derive reliable conceptual models to describe flow in fractured porous media. The fracture aperture is several orders of magnitude smaller than the characteristic ... -
Dimensional reduction of a fractured medium for a two-phase flow
(Journal article; Peer reviewed, 2022)We consider a porous medium containing a single fracture, and identify the aperture to length ratio as the small parameter ɛ with the fracture permeability and the fracture porosity scaled as exponents of ɛ. We consider a ... -
Discrete Approximations of BV solutions to Doubly Nonlinear Degenerate Parabolic Equations

Discussion about the role of teacher authority when making a transition into creative problem-solving in mathematics
(Journal article; Peer reviewed, 2023)When introducing a new kind of teaching activity into the classroom, the teacher cannot foresee whether the students will accept it or not. Even when the students do, there is a risk, that they might be neither able nor ... -
A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(Master thesis, 2010-05-26)The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ... -
Dispersive Estimates for Full Dispersion KP Equations
(Journal article; Peer reviewed, 2021)We prove several dispersive estimates for the linear part of the Full Dispersion Kadomtsev–Petviashvili introduced by David Lannes to overcome some shortcomings of the classical Kadomtsev–Petviashvili equations. The proof ... -
The dissolution of a miscible drop rising or falling in another liquid at low Reynolds number
(Journal article; Peer reviewed, 2023)“A basic and basically unsolved problem in fluid dynamics is to determine the evolution of rising bubbles and falling drops of one miscible liquid in another” [D. D. Joseph and Y. Y. Renardy, Fundamentals of Two-Fluid ... -
Diurnal gait fluctuations in single- and dual- task conditions
(Journal article; Peer reviewed, 2020)Gait is one of the most basic movements, and walking activity accomplished in dual task conditions realistically represents daily life mobility. Much is known about diurnal variations of gait components such as muscle ... -
Divided differences and ideals generated by symmetric polynomials
(Department of Pure Mathematics report no. 59, Research report, 1991-04) -
Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2014-09-18)Background: Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP), but it is not known if there is any causal relationship. Objective: The objective was to determine, ... -
Does diabetes influence the probability of experiencing chronic low back pain? A population-based cohort study: the Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2019)Objective: Low back pain (LBP) is a major problem in modern society and it is important to study possible risk factors for this disorder. People with diabetes are often affected by LBP, but whether diabetes represents a ...
