Acoustic and Boundary Layer Comparisons Between Navier-Stokes and Svärd's Modified Navier-Stokes Equations
(Master thesis, 2021-12-22) -
Active and integrated management of water resources throughout CO2 capture and sequestration operations
(Peer reviewed; Journal article, 2011)Most projected climate change mitigation strategies will require a significant expansion of CO2 Capture and Sequestration (CCS) in the next two decades. Four major categories of challenges are being actively researched: ... -
Adaptive asynchronous time-stepping, stopping criteria, and a posteriori error estimates for fixed-stress iterative schemes for coupled poromechanics problems
(Journal article; Peer reviewed, 2020)In this paper we develop adaptive iterative coupling schemes for the Biot system modeling coupled poromechanics problems. We particularly consider the space–time formulation of the fixed-stress iterative scheme, in which ... -
Adaptive Characteristic Operator Splitting Techniques for Convection-Dominated Diffusion Problems in One and Two Space Dimensions
(Department of Applied Mathematics report;85, Research report, 1988-12) -
Adaptive Multiscale Methods Based on A Posteriori Error Estimates
(Master thesis, 2010-06-01)We give an overview of different methods for solving highly heterogeneous elliptic problems with multiscale structure and no intuitive scale separation. We compare different finite element variational multiscale methods ... -
Adaptive parameterization of electric conductivity in inversion of electromagnetic data
(Master thesis, 2012-06-01)We describe a methodology developed for 3-D parameter identification, with focus on large-scale applications such as monitoring subsea oil production and geothermal systems. The methodology is designed to handle challenges ... -
An adaptive solution strategy for Richards' equation
(Journal article; Peer reviewed, 2023)Flow in variably saturated porous media is typically modeled by the Richards equation, a nonlinear elliptic-parabolic equation which is notoriously challenging to solve numerically. In this paper, we propose a robust and ... -
Addressing class imbalance in deep learning for acoustic target classification
(Journal article; Peer reviewed, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -
Admissibility conditions for Riemann data in shallow water theory
(Journal article; Peer reviewed, 2020)Consideration is given to the shallow-water equations, a hyperbolic system modeling the propagation of long waves at the surface of an incompressible inviscible fluid of constant depth. It is well known that the solution ... -
Advection Upscaling for Heat Transport in Fractured Geothermal Reservoir
(Master thesis, 2018-06-20)The main objective in this thesis is to give numerical solution for advection term of heat transport equation in fractured geothermal reservoir. To get better insight in the fracture influence on the processes we will ... -
Algebra i første klasse
(Master thesis, 2015-10-12)Oppgaven handler om algebra i første klasse. Hva er tidlig algebra og hvordan kan vi undervise på en slik måte at vi utvikler elevenes algebraiske tenkning? Tidlig algebra er ikke at vi underviser skolealgebra tidligere, ... -
Algebra i norske lærebøker. En analyse av tre lærebøker for 8. trinn
(Master thesis, 2024-06-03)Denne masteroppgaven undersøker presentasjonen og struktureringen av algebra i tre utvalgte norske lærebøker i matematikk for 8.trinn. Motivasjonen for studien stammer fra de vedvarende utfordringene norske elever møter i ... -
Algebravansker. Hva er årsaken til at elevene syns algebra er vanskelig? Er det hull i grunnleggende kunnskap og/eller misoppfatninger hos elever på videregående skole som gjør at algebra er vanskelig for dem?
(Master thesis, 2017)I denne oppgaven kommer det fram hva årsaken og problemer elever på videregående kan ha i algebra som gjør at de syns algebra er vanskelig, og gjør det dårlig i dette emnet. Resultatene fra TIMSS Advanced i 2015 viser at ... -
An algorithm for internal morging of two subsets with small extra storage requirements.
(Department of Applied Mathematics report;50, Research report, 1974-09) -
Algoritmisk tenkning og kreativitet
(Master thesis, 2023-06-01)Den raske teknologiutviklingen har ført til at det stadig stilles nye krav til befolkningens kompetanse og ferdigheter. Algoritmisk tenkning og kreativitet anses som essensielle ferdigheter i det 21.århundre. Gjennom ... -
Alterations in auditory brain stem response distinguish occasional and constant tinnitus
(Journal article; Peer reviewed, 2022)BACKGROUND. The heterogeneity of tinnitus is thought to underlie the lack of objective diagnostic measures. METHODS. Longitudinal data from 20,349 participants of the Swedish Longitudinal Occupational Survey of Health ... -
Altered collective mitochondrial dynamics in the Arabidopsis msh1 mutant compromising organelle DNA maintenance
(Journal article; Peer reviewed, 2022)Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be ... -
Alternative læringsmåter for derivasjon i R1 - en komparativ analyse
(Master thesis, 2016-06-01)I denne masteroppgaven har jeg studert elever som har arbeidet med derivasjon i matematikk R1. Formålet har vært å sammenligne to alternative læringsmåter med tradisjonell oppgaveregning, med tanke på læringsutbytte på ... -
