Analysis of wind and response measurement data from a suspension bridge
König, René (Master thesis, 2023)The Lysefjord Bridge is a suspension bridge at the entrance to the Lysefjord in south-western Norway at which full-scale measurements on wind conditions and bridge response are collected using anemometers and accelerometers. ... -
Compaction and Fluid—Rock Interaction in Chalk Insight from Modelling and Data at Pore-, Core-, and Field-Scale
Minde, Mona Wetrhus; Hiorth, Aksel (Peer reviewed; Journal article, 2020)Water weakening is a phenomenon that is observed in high porosity chalk formations. The rock interacts with ions in injected water and additional deformation occurs. This important effect needs to be taken into account ... -
Compaction of fine granular calcite by pressure solution at high temperature and stress with and without organic additive in pore fluid
Hovden, Tonje (Masteroppgave/UIS-TN-IØRP/2018;, Master thesis, 2018-06-15)Pressure solution is a compaction mechanism that reduces both porosity and permeability. It is a common and important water-rock interaction process and it is a widespread phenomenon that influences many essential natural ... -
Data Driven Model Discovery - Petroleum application
Søndeland, Sander André (Master thesis, 2023)The SINDy algorithm is a data driven algorithm that discovers dynamical system in data that evolves over time. The method can be utilized for every dataset that evolves over time. In this study we have looked the Lorenz ... -
Estimating cardiac output from coronary CT angiography: an individualized compartment model in comparison to the Stewart–Hamilton method
Leiknes, Jon Bjarne; Hiorth, Aksel; Havnen, Jorunn; Greve, Ole Jacob; Kurz, Kathinka Dæhli; Larsen, Alf Inge (Peer reviewed; Journal article, 2023)Background: Attenuation is correlated with the concentration of contrast medium (CM) in the arteries. The cardiac output (CO) affects the concentration of CM in the circulatory system; therefore, CO affects the time–density ... -
Modeling energy consumption and heat exchange of buildings
Skarås, Steffen Berntsen (Master thesis, 2021)High energy demand and the use of greenhouse gases are issues of today’s world. The world has a higher energy consumption now than ever before, and it is estimated to increase further. With the rise of renewable energy, ... -
Modeling Energy Consumption and Heat Exchange of Buildings
Khan, Usman Ali (Master thesis, 2023)This research thesis investigates energy consumption and thermal dynamics in buildings, with a focus on achieving energy efficiency and indoor comfort in cold-climate regions like Norway. There is a necessity for the ... -
A new formulation of the surface charge/surface potential relationship in electrolytes with valence less than three
Nødland, Oddbjørn Mathias; Hiorth, Aksel (Peer reviewed; Journal article, 2023)Surface complexation models (SCMs) based on Gouy-Chapman theory are often used to describe adsorption of ions onto mineral surfaces. To compensate for the buildup of charge at a solid surface, the composition of the electric ... -
Relative Geologic Time By Dynamic Time Warping
Strøm, Aleksander S. (Master thesis, 2022)This thesis considers an approach to tackle a core problem within seismic interpretation, which is bringing an autonomously generated interpretation of the seismic data, which is now known as a Relative Geologic Time. The ... -
Streaming Potential in Porous Media - Single and Two-Phase
White, Sebastian (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The streaming potential method is a promising method to measure how surface potential change when different fluids are injected into a rock. The understanding of how and why the surface potential changes can give important ... -

The Generation of Synthetic Healthcare Data Using Deep Neural Networks
Hossein Zadeh Nik, Alireza (Master thesis, 2022)High-quality tabular data is a crucial requirement for developing data-driven applications, especially healthcare-related ones, because most of the data nowadays collected in this context is in tabular form. However, strict ... -
Topology Optimization Using the Lattice Boltzmann Method
Hoch, Angela (Master thesis, 2021)Human design is limited by our ideas of geometries. Topology optimization is a tool to cross that barrier and improve design especially for applications that are irrevocable once they are in use. This thesis presents a ... -
Water shut-off with polymer - core study application for the Alvheim Field
Tønnessen, Marie (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)This thesis is an experimental study where different polymers have been evaluated for disproportionate permeability reduction (DPR) effects. The laboratory work was performed at Norce, for Aker BP, as a part of the Master’s ...
