A comprehensive evaluation of predictive performance of 33 species distribution models at species and community levels
(Journal article; Peer reviewed, 2019)A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages. Given the wealth of existing models, it is unclear ... -
A Conditional Bound for the Riemann zeta-function in the Critical Line
(Master thesis, 2022)Denne oppgaven bestemmer eksplisitte konstanter for den øvre begrensningen av logaritmen til Riemann zeta-funksjonen på den kritiske linja, under antakelsen av Riemann-hypotesen. Dette krever to betraktninger. Vi finner ... -
A Conjoint Analysis Applied to Consumers Choice of Tablets.
(Master thesis, 2019)Conjoint analysis is increasingly used in the applied consumers choice of products and services. This method is widely applied in many market research projects. In this thesis, we used the conjoint analysis applied to ... -
A Construction of Peak Functions on Weakly Pseudoconvex Domains
(Bachelor thesis, 2021)Som forberedelse til å konstruere det som kalles "peak functions" så studerer vi egenskaper til subharmoniske polynomer. -
A Continuous-Time, Discrete-Space Statistical Model for Estimating Dispersal Rate Applied to a Population of House Sparrows (Passer Domnesticus) in Northern Norway
(Master thesis, 2015)How individuals move and interact with each other is a complex matter. Even so, the knowledge of how such movements and interactions happen is important to understand in order to be able to keep genetic variation and ... -
A control problem related to the parabolic dominative p-Laplace equation
(Journal article; Peer reviewed, 2019)We show that value functions of a certain time-dependent control problem in Ω × (0, T), with a continuous payoff F on the parabolic boundary, converge uniformly to the viscosity solution of the parabolic dominative p-Laplace ... -
A Convergent Crank-Nicolson Galerkin Scheme for the Benjamin-Ono Equation
(Master thesis, 2016)In this thesis we prove the convergence of a Crank--Nicolson type Galerkin finite element scheme for the initial value problem associated to the Benjamin--Ono equation. The proof is based on a recent result for a similar ... -
A Convergent Crank–Nicolson Galerkin Scheme for the Benjamin–Ono Equation
(Journal article; Peer reviewed, 2018)In this paper we prove the convergence of a Crank–Nicolson type Galerkin finite element scheme for the initial value problem associated to the Benjamin–Ono equation. The proof is based on a recent result for a similar ... -
A cut finite element method for the biharmonic problem and its application to the Cahn-Hilliard equation
(Master thesis, 2023)Cahn-Hilliard-ligningen har et bredt av anvendelser innen fase-separasjon, men gir numeriske utfordringer på grunn av sin ikke-linearitet, stivhet og fjerdeordens deriverte. I denne avhandlingen introduserer vi en ny og ... -
A detailed account of Behrens proof of Bott periodicity
(Master thesis, 2020)We give a detailed account of Behrens' proof of real and complex Bott periodicity theorem which is based on the ideas by McDuff. We include thorough computations and some intuition behind constructions and con- cepts. The ... -
A Domain with Non-plurisubharmonic Squeezing Function
(Journal article; Peer reviewed, 2018)We construct a strictly pseudoconvex domain with smooth boundary whose squeezing function is not plurisubharmonic. -
A Fatou-Bieberbach Domain with a Complex Line in the Boundary
(Master thesis, 2018)The purpose of this thesis is to construct a Fatou-Bieberbach domain in two complex variables with a complex line in the boundary. To achieve this, we will first explore the dynamics of an analytic transformation in one ... -
A feasibility study for road and weather information and variable speed limits

A Framework for Describing and Analyzing Anonymity Networks
(Master thesis, 2019)Oppgaven introduserer et rammeverk som tillater en idealisering av anonymitetesnettverk og netverksimulering. En hovedfordel med dette rammeverket er at anonyitetskarakterestikker kan bli definert for en spesifik ... -
A full-scale 3D Vs 2.5D Vs 2D analysis of flow pattern and forces for an industrial-scale 5MW NREL reference wind-turbine
(Journal article; Peer reviewed, 2017)NREL 5MW reference turbine, which is a popular, realistic and standardized industrial scale offshore turbine model, is used in this work for understanding the associated flow-complexities and for testing models. For such ... -
A fully implicit WENO scheme on stratigraphic and unstructured polyhedral grids
(Journal article; Peer reviewed, 2019)Many authors have used higher-order spatial discretizations to reduce numerical diffusion, which can be particularly pronounced when simulating EOR processes involving active chemical substances that are transported by ... -
A General Face Recognition System
(Master thesis, 2006)In this project a real-time face detection and recognition system has been discussed and implemented. The main focus has been on the detection process which is the first and most important step before starting with the ... -
A General Nonlinear Reservoir Simulator with the Full Approximation Scheme
(Master thesis, 2018)Simulation of multiphase flow and transport in porous rock formations gives rise to large systems of strongly coupled nonlinear equations. Solving these equations is computationally challenging because of orders of magnitude ... -
A heavy tailed statistical model applied in anti-collision calculations for petroleum wells
(Master thesis, 2008)Anti-collision calculations are done during the planning of a new petroleum well. These calculations are required in order to control the risk of having a well-collision, which is an unwanted event at any cost. The risk ... -
A homological approach to the Poincaré--Birkhoff--Witt theorem
