A Comparison of the local Gaussian correlation and the local dependence function
(Master thesis, 2022-06-01)Correlation is a method to measure the relation between two or more variables. In this thesis, a method of measuring correlation and a method of measuring dependence are used. These two methods, are the local Gaussian ... -
A delayed SEIR-model of the Covid-19 pandemic
(Master thesis, 2022-06-01) -
A Dimensionality Reducing Extension of Bayesian Relevance Learning
(Master thesis, 2021-02-11)When modeling with big data and high dimensional data, the ability to extract the most important information from the data set and avoid overfitting is crucial. However, by using well developed sparse methods, we can ... -
A numerical study of water exchange in sill fjords and the effect of coastal climate change
(Master thesis, 2019-05-27)The dynamics of basin water exchange in sill fjords are governed by external factors. This thesis addresses how climate change on the coast may affect the water exchange of the basin water. A three-dimensional hydrostatic ... -

An accelerated staggered scheme for variational phase-field models of brittle fracture
(Journal article; Peer reviewed, 2021)There is currently an increasing interest in developing efficient solvers for variational phase-field models of brittle fracture. The governing equations for this problem originate from a constrained minimization of a ... -
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, 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 ... -
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, ... -
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.
