Robust Monolithic Solvers for the Stokes--Darcy Problem with the Darcy Equation in Primal Form
(Journal article; Peer reviewed, 2022)We construct mesh-independent and parameter-robust monolithic solvers for the coupled primal Stokes--Darcy problem. Three different formulations and their discretizations in terms of conforming and nonconforming finite ... -
Robust Multiscale Control-volume Methods for Reservoir Simulation
(Doctoral thesis, 2012-04-30) -
A robust Nonconforming H²-Element
(Department of Applied Mathematics report, Research report, 1999-03) -
Robust nonlinear regression estimation in null recurrent time series
(Journal article; Peer reviewed, 2021)In this article, we study parametric robust estimation in nonlinear regression models with regressors generated by a class of non-stationary and null recurrent Markov processes. The nonlinear regression functions can be ... -
Robust Optimization for Sequential Field Development Planning
(Doctoral thesis, 2021-09-24)To achieve high profitability from an oil field, optimizing the field development strategy (e.g., well type, well placement, drilling schedule) before committing to a decision is critically important. The profitability at ... -
Robust simulation of sharp-interface models for fast estimation of CO2 trapping capacity in large-scale aquifer systems
(Peer reviewed; Journal article, 2016-02)Modeling geological carbon storage represents a new and substantial challenge for the subsurface geosciences. To increase understanding and make good engineering decisions, containment processes and large-scale storage ... -
Robust solvers for fully coupled transport and flow in saturated/unsaturated porous media
(Doctoral thesis, 2021-03-29)Numerical simulations and laboratory studies are our main tools to comprehend better processes happening in the subsurface. The phenomena are modeled thanks to systems of partial differential equations (PDEs), which are ... -
Robust uncertainty assessment of the spatio-temporal transferability of glacier mass and energy balance models
(Peer reviewed; Journal article, 2019-02-08)Energy and mass-balance modelling of glaciers is a key tool for climate impact studies of future glacier behaviour. By incorporating many of the physical processes responsible for surface accumulation and ablation, they ... -
Robusthet og sikkerhet i en åpen situasjon
(Master thesis, 2008)The aim of this study was to investigate if the evaluation of risk and safety contributes to behavior over and above measures of hardiness and resilience in an open situation. Data was collected from a survey prior to an ... -
Robusthet ved skadereservering - Chain-Ladder og influens funksjoner
(Master thesis, 2011-06-01)I denne oppgaven har jeg sett på hvordan uteliggere kan påvirke IBNR reserven i skadereservering. Jeg har studert influens funksjoner for den klassiske Chain-Ladder metoden, og videre sett at uteliggere kan påvirke ... -
Robustness and Model Selection in Configurational Causal Modeling
(Journal article; Peer reviewed, 2021)In recent years, proponents of configurational comparative methods (CCMs) have advanced various dimensions of robustness as instrumental to model selection. But these robustness considerations have not led to computable ... -
Rock Carvings of Taru Thang. The mountain goat: A religous and social symbol of the Dardic speaking people of the trans-Himalayas
(Master thesis, 2008-11-18)A study of the rock carvings of Taru Thang in Ladakh. I have tried to show how the mountain goat symbol so often depicted in the rock art might have been made by Dardic speaking groups in order to map out and understand ... -
Rock physics and seismic AVA analysis of gas hydrate-bearing sediments
(Master thesis, 2014-06-02)Large amount of natural gas are present in submarine sediments and permafrost areas in the form of gas hydrates. Gas hydrates are a large potential future energy resource, and may contribute to the methane balance in the ... -
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Peer reviewed; Journal article, 2010)Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we incorporate ... -
Rock Physics Templates for 4D Seismic Reservoir Monitoring: A case study from Yttergryta field in the Norwegian Sea
(Master thesis, 2014-06-02)Time-lapse 3D seismic which geoscientists often abbreviate to 4D seismic has the potential to monitor changes especially in pore pressure, hydrocarbon and brine saturation in a reservoir due to production or water/gas ... -
Rock sponges (lithistid Demospongiae) of the Northeast Atlantic seamounts, with description of ten new species
(Journal article; Peer reviewed, 2020)Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their ... -

Role for ribosome-associated quality control in sampling proteins for MHC class I-mediated antigen presentation
(Journal article; Peer reviewed, 2020)Pathogens and tumors are detected by the immune system through the display of intracellular peptides on MHC-I complexes. These peptides are generated by the ubiquitin−proteasome system preferentially from newly synthesized ...
