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 ... -
Practical approaches to study microbially induced calcite precipitation at the field scale
(Journal article; Peer reviewed, 2021)Microbially induced calcite precipitation (MICP) is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; therefore, this technology has a potential to ... -
Pre- and post-lie algebras: The algebro-geometric view
(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 ... -
Precision identification of high-risk phenotypes and progression pathways in severe malaria without requiring longitudinal data
(Peer reviewed; Journal article, 2019)More than 400,000 deaths from severe malaria (SM) are reported every year, mainly in African children. The diversity of clinical presentations associated with SM indicates important differences in disease pathogenesis that ... -
Preconditioning for Flow in Fractured Porous Media
(Doctoral thesis, 2020-01-24)The key to reliable simulations of flow in fractured porous media is the proper design, analysis and implementation of numerical methods. These methods should take into account the specific properties of the underlying ... -
Prevalence of molar incisor hypomineralization among school children in Rome, Italy
(Journal article; Peer reviewed, 2022)Molar incisor hypomineralization (MIH) is a highly prevalent condition associated with increased caries experience, dental pain and treatment need. Aim of this study was to determine the prevalence and severity of MIH in ... -
Probability distributions of surface gravity waves during spectral changes

Punktprosessmodeller for linjetransektdata
(Master thesis, 2010-04-27)Oppgaven omhandler punktprosesser som modell for observasjoner ved en transektlinje. Hovedprosessen er en Markovmodulert Poissonprosess som tillater at punkter opptrer oftere i noen perioder enn andre, den er her begrenset ... -
PyProp - A Python Framework for Propagating the Time Dependent Schrödinger Equation

Quality of the Analysis Step in EnKF
(Master thesis, 2011-06-15)In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons from ... -
Quantification and uncertainty of root growth stimulation by elevated CO2 in a mature temperate deciduous forest
(Journal article; Peer reviewed, 2023)Increasing CO2 levels are a major global challenge, and the potential mitigation of anthropogenic CO2 emissions by natural carbon sinks remains poorly understood. The uptake of elevated CO2 (eCO2) by the terrestrial ... -
Quantifying prior model complexity for subsurface reservoir models
(Journal article; Peer reviewed, 2023)In Bayesian approaches to history matching for subsurface inference, the prior model specifies the uncertain model parameters and the joint probability of those parameters before incorporating production-related data. A ... -
Quantifying uncertainties when monitoring marine environments in connection with geological storage of CO2
(Doctoral thesis, 2015-06-26) -
Quenched invariance principle for random walks on dynamically averaging random conductances
(Journal article; Peer reviewed, 2021)We prove a quenched invariance principle for continuous-time random walks in a dynamically averaging environment on Z. In the beginning, the conductances may fluctuate substantially, but we assume that as time proceeds, ... -
Radial processes for sub-Riemannian Brownian motions and applications
(Journal article; Peer reviewed, 2020)We study the radial part of sub-Riemannian Brownian motion in the context of totally geodesic foliations. Itô’s formula is proved for the radial processes associated to Riemannian distances approximating the Riemannian ...
