Symmetric spaces and Lie triple systems in numerical analysis of differential equations
(Peer reviewed; Journal article, 2014-03)A remarkable number of different numerical algorithms can be understood and analyzed using the concepts of symmetric spaces and Lie triple systems, which are well known in differential geometry from the study of spaces of ... -
Symmetric Spaces Rolling on Flat Spaces
(Journal article; Peer reviewed, 2023)The objective of the current paper is essentially twofold. Firstly, to make clear the difference between two notions of rolling a Riemannian manifold over another, using a language accessible to a wider audience, in ... -
Symmetric waves are traveling waves of some shallow water scalar equations
(Journal article; Peer reviewed, 2023)Following a straightforward proof for symmetric solutions to be traveling waves by Pei (Exponential decay and symmetry of solitary waves to Degasperis-Procesi equation. Journal of Differential Equations. 2020;269(10):7730-7749), ... -
Symmetry and simplicity spontaneously emerge from the algorithmic nature of evolution
(Journal article; Peer reviewed, 2022)Engineers routinely design systems to be modular and symmetric in order to increase robustness to perturbations and to facilitate alterations at a later date. Biological structures also frequently exhibit modularity and ... -
Syntetisk CDO: iTraxx-prising ved bruk av en Normal Invers Gaussisk Copula
(Master thesis, 2013-04-04)I denne oppgaven skal vi se at det er et stort marked for kredittderivater etter finanskrisen, men da i en vridning mot syntetiske varianter. Men framtidsutsiktene er usikre, da disse produktene er i en særstilling når det ... -
Temporal Scale-Dependent Sensitivity Analysis for Hydrological Model Parameters Using the Discrete Wavelet Transform and Active Subspaces
(Journal article; Peer reviewed, 2021)Global sensitivity analysis is an important step in the process of developing and analyzing hydrological models. Measured data of different variables are used to identify the number of sensitive model parameters and to ... -

Theta-Regularity and Log-Canonical Threshold
(Master thesis, 2018-05-30)The log-canonical threshold is an invariant that is widely used in modern birational geometry. It contains information regarding the singularities of sheaves of ideals. The theta-regularity index is a regularity condition ... -

Threshold estimation based on local minima for nucleus and cytoplasm segmentation
(Journal article; Peer reviewed, 2022)Background: Image segmentation is the process of partitioning an image into separate objects or regions. It is an essential step in image processing to segment the regions of interest for further processing. We propose a ... -
Time Series: Forecasting and Evaluation Methods With Concentration On Evaluation Methods for Density Forecasting
(Master thesis, 2018-06-06)The main focus of this thesis are density forecasts and the corresponding evaluation methods. A density forecast is an estimate of the probability density of predicted values. Density forecasts and the related evaluation ... -

Tinnitus Is Marginally Associated with Body Mass Index, Heart Rate and Arterial Blood Pressure: Results from a Large Clinical Sample
(Journal article; Peer reviewed, 2023)Introduction: This study aimed to explore whether body mass index (BMI), systolic blood pressure (RR syst), diastolic blood pressure (RR diast) or heart rate (HR) are associated with tinnitus status and/or severity. Methods: ... -
A TMB Approach to Study Spatial Variation in Weather-Generated Claims in Insurance
(Journal article; Peer reviewed, 2023)In this paper, we use TMB to study spatial variation in weather-generated claims in insurance. Our motivation is twofold. By comparing with INLA, we first find that TMB is a robust and efficient approach to deal with spatial ... -
Tokamerarekonstruksjon og Gröbnerbasar
(Master thesis, 2016-06-01)I denne oppgåva skal me sjå på korleis ein skal gå fram for å rekonstruere ei scene frå to bilete. Dette kan brukast når ein skal evaluere satellittbilete og gjere ei kalibrering av kamera. Me skal sjå på geometrien og ... -
Topographic effects on buoyancy driven flows along the slope
(Journal article; Peer reviewed, 2022)The flow and descent of dense water masses formed in shallow regions of the ocean is an important leg in the global overturning circulation. The dense overflow waters tend to flow along the continental slopes as geostrophically ... -

Total Variation Regularization of Matrix-Valued Images
(Peer reviewed; Journal article, 2007)We generalize the total variation restoration model, introduced by Rudin, Osher, and Fatemi in 1992, to matrix-valued data, in particular, to diffusion tensor images (DTIs). Our model is a natural extension of the color ...
