Parameter Estimation of Multivariate Factor Stochastic Volatility Models
(Master thesis, 2018-06-22)Volatility is a crucial aspect of risk management and important to accurately quantify. A broad range of models and methods tackle this problem, but there is no consensus to exactly which method or model that solves this ... -
Parameter estimation with the augmented Lagrangian method for a parabolic equation.
(Department of Applied Mathematics report, Research report, 2001-01) -
Passer og linjal, origami og Galoisteori
(Master thesis, 2011-06-01)Denne oppgaven prøver å belyse konstruksjoner med passer og linjal og origami ved hjelp av Galois- teori. De tre klassiske problemene: Kubens fordobling, sirkelens kvadratur og vinkelens tredeling er sentrale. Oppgaven er ... -
PDE Based Algorithms for Smooth Watersheds
(Peer reviewed; Journal article, 2016-04)Watershed segmentation is useful for a number of image segmentation problems with a wide range of practical applications. Traditionally, the tracking of the immersion front is done by applying a fast sorting algorithm. In ... -
Permeability estimation with the Augmented Lagrangian method for a nonlinear diffusion equation.
(Department of Applied Mathematics report, Research report, 2001-01) -
Persistent Homology via Quotient Spaces
(Master thesis, 2017-12-20)A point cloud can be endowed with a topological structure by constructing a simplicial complex using the points as vertices. Instead of assigning a single simplicial complex, Topological Data Analysis (TDA) employs multiple ... -
Perturbation about neutral solutions occurring in shear flows in stratified, incompressible and inviscid fluids.
(Department of Applied Mathematics report, Research report, 1973-06) -
Physical activity level at work and risk of chronic low back pain: A follow-up in the Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2017-04-10)Background: Physical activity in leisure time seems to reduce the risk of low back pain, but it is not known whether occupational activity, as recorded in a representative working population, produces a higher or lower ... -
Polish Translation and Validation of the Tinnitus Handicap Inventory and the Tinnitus Functional Index
(Peer reviewed; Journal article, 2016-11-29)Objective: The need for validated measures enabling clinicians to classify tinnitus patients according to the severity of tinnitus and screen the progress of therapies in our country led us to translate into Polish and to ... -
Polynomials homologically supported on determinantal loci
(Department of Pure Mathematics report no. 61, Research report, 1991-10) -
A pore network model for calculation of interfacial velocities
(Peer reviewed; Journal article, 2003)Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for saturation ... -
A pore-scale model for permeable biofilm: Numerical simulations and laboratory experiments
(Peer reviewed; Journal article, 2019)In this paper, we derive a pore-scale model for permeable biofilm formation in a two-dimensional pore. The pore is divided into two phases: water and biofilm. The biofilm is assumed to consist of four components: water, ... -
Portfolio Optimization in a Lévy Market with Intertemporal Substitution and Transaction Costs
(Department of Applied Mathematics report, Research report, 2000-05) -
Portfolio Optimization with PCC-GARCH-CVaR model
(Master thesis, 2014-06-02)This thesis investigates the Conditional Value-at-Risk (CVaR) portfolio optimization approach combined with a univariate GARCH model and pair-copula constructions (PCC) to determine the optimal asset allocation for a ... -
Post-lie algebras and isospectral flows
(Peer reviewed; Journal article, 2015-11-20)In this paper we explore the Lie enveloping algebra of a post-Lie algebra derived from a classical R-matrix. An explicit exponential solution of the corresponding Lie bracket flow is presented. It is based on the solution ... -
Postinjection Normal Closure of Fractures as a Mechanism for Induced Seismicity
(Peer reviewed; Journal article, 2017-10-04)Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced ... -
Potensialet for dyp geotermisk energi i Norge: Modellering av varmeutvinning fra konstruerte geotermiske system
(Master thesis, 2010-10-05)Dette prosjektet tar for seg to ulike modeller for et konstruert geotermisk system; et lukket enkeltbrønn-system og et åpent, sprekkdominert system. Enkeltbrønn-systemet er modellert eksplisitt, og modellen er også tilpasset ... -
Pre- and post-lie algebras: The algebro-geometric view
(Conference object; Peer reviewed; Journal article, 2019)We relate composition and substitution in pre- and post-Lie algebras to algebraic geometry. The Connes-Kreimer Hopf algebras and MKW Hopf algebras are then coordinate rings of the infinite-dimensional affine varieties ...
