Metamodeling of the Electrical Conditions in Submerged Arc Furnaces
(Peer reviewed; Journal article, 2021)Physics-based Finite Element Methods models can be used to investigate the electrical conditions in submerged arc furnaces (SAFs). However, their explicit solution may be very demanding in terms of time and computational ... -
Microbial hydrogen consumption leads to a significant pH increase under high-saline-conditions: implications for hydrogen storage in salt caverns
(Peer reviewed; Journal article, 2023)Salt caverns have been successfully used for natural gas storage globally since the 1940s and are now under consideration for hydrogen (H2) storage, which is needed in large quantities to decarbonize the economy to finally ... -
Microfluidic study of effects of flow velocity and nutrient concentration on biofilm accumulation and adhesive strength in the flowing and no-flowing microchannels
(Peer reviewed; Journal article, 2019)Biofilm accumulation in porous media can cause pore plugging and change many of the physical properties of porous media. Engineering bioplugging may have significant applications for many industrial processes, while improved ... -
Modeling of Environmental Fate and Effects of Oil Leakages from Abandoned Subsea Wells Using an Environmental Impact Factor Tool
(Peer reviewed; Journal article, 2021)Potential environmental consequences of oil leakages (i.e., continuous uncontrolled releases at low flow rate over a long period of time) need to be taken into consideration in the ongoing development of plug and abandonment ... -
Modeling of relative permeabilities including dynamic wettability transition zones
(Peer reviewed; Journal article, 2021)Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in a porous medium. There are reservoir fluids that provoke the surface within pores to undergo a wettability change. This ... -
Monolithic and splitting solution schemes for fully coupled quasi-static thermo-poroelasticity with nonlinear convective transport
(Peer reviewed; Journal article, 2020)This paper concerns monolithic and splitting-based iterative procedures for the coupled nonlinear thermo-poroelasticity model problem. The thermo-poroelastic model problem we consider is formulated as a three-field system ... -
Multi-agent informed path planning using the probability hypothesis density
(Peer reviewed; Journal article, 2020)An Informed Path Planning algorithm for multiple agents is presented. It can be used to efficiently utilize available agents when surveying large areas, when total coverage is unattainable. Internally the algorithm has a ... -
Multilevel Assimilation of Inverted Seismic Data With Correction for Multilevel Modeling Error
(Journal article; Peer reviewed, 2021)With large amounts of simultaneous data, like inverted seismic data in reservoir modeling, negative effects of Monte Carlo errors in straightforward ensemble-based data assimilation (DA) are enhanced, typically resulting ... -
Novel iterative ensemble smoothers derived from a class of generalized cost functions
(Peer reviewed; Journal article, 2021)Iterative ensemble smoothers (IES) are among the state-of-the-art approaches to solving history matching problems. From an optimization-theoretic point of view, these algorithms can be derived by solving certain stochastic ... -
A numerical study of flow field and particle deposition in nasal channels with deviant geometry
(Peer reviewed; Journal article, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
An old game, new experience: exploring the effect of players’ personal gameplay history on game experience.
(Journal article; Peer reviewed, 2022)This experimental study explores how game experience differs between players with different gameplay histories within the same game universe. We are interested in how prolonged engagement with a game series affects the ... -
On the Organisation of Translation—An Inter- and Transdisciplinary Approach to Developing Design Options for CO2 Storage Monitoring Systems
(Peer reviewed; Journal article, 2022)Interdisciplinary and transdisciplinary collaboration has become a common practice in technology development projects. Rarely, however, the integration (and translation) of knowledge from different disciplines and different ... -
On the use of criteria based on the SMART acronym to assess quality of performance indicators for safety management in process industries
(Peer reviewed; Journal article, 2021)Management of safety, and barriers in particular, includes using information expressing performance, i.e. use of safety performance indicators. For this information to be useful, the indicators should demonstrate adequate ... -
On the use of the vision zero principle and the ALARP principle for production loss in the oil and gas industry
(Peer reviewed; Journal article, 2019)In the oil and gas industry, there is a strong focus on reducing production loss, and in the last decade the industry has adopted Vision Zero as a governing principle, to meet this goal. A previous paper has concluded that, ... -
An Overall Furnace Model for the Silicomanganese Process
(Journal article; Peer reviewed, 2021)Controlling and optimizing smelting processes in submerged-arc furnaces are complicated by the limited amount of information available regarding the internal conditions. Computer models can help to bridge this knowledge ... -
Overview of the Potential of Energy Harvesting Sources in Electric Vehicles
(Peer reviewed; Journal article, 2023)Energy harvesting, a cutting-edge technology that captures wasted energy from vehicles, constitutes a means to improve the efficiency of electric vehicles. Dissipated energy can be converted into electricity using regenerative ... -
p-Kernel Stein Variational Gradient Descent for Data Assimilation and History Matching
(Journal article; Peer reviewed, 2021)A Bayesian method of inference known as “Stein variational gradient descent” was recently implemented for data assimilation problems, under the heading of “mapping particle filter”. In this manuscript, the algorithm is ... -
Participatory Design of VR Scenarios for Exposure Therapy
