Urban Density and Accessibility: A methodological approach
(Peer reviewed; Journal article, 2024)The built environment’s impact on human behaviour is well-documented. Still, quantitative research on the topic usually focuses on a large scale, with few studies at the neighbourhood level. This study presents a method ... -
Cuttings Transport With Oil- and Water-Based Drilling Fluids
(Peer reviewed; Journal article, 2024-01)Deviated well sections are common in most modern offshore well construction designs. In the North Sea region, which is a good example of mature areas, practically all producer or injector wells have highly deviated well ... -
Rapportering og avvik
(Bachelor thesis, 2024)I denne oppgaven er hensikten å se på temaet helse, miljø og sikkerhet relatert til avviksrapportering, samt å se på sikkerhetskulturen som støtter dette hjelpemiddelet. Oppgaven går over forskjellige vitenskapelige artikler ... -
Experimental assessment of cracked tubular joints repaired with crack-deflecting holes and weld-toe grinding
(Master thesis, 2023)Fatigue-induced cracks in tubular joints represent one of the major threats to the structural integrity of offshore infrastructure. Consequently, developing and researching efficient temporary and permanent repair solutions ... -
Destabilization of crude oil sludges by chemical and mechanical treatment
(Master thesis, 2022)The demand for petroleum is still increasing. As a result, various wastes are generated during exploration and production, even though strict rules and regulations are applied to oil and gas industries to optimize waste ... -
Hvordan kan granskning etter uønskede hendelser bidra til organisatorisk læring hos en boreentreprenør?
(Master thesis, 2022)Ett av hovedformålene med granskning av uønskede hendelser er å lære, for å unngå at lignende hendelser skjer igjen. I petroleumsindustrien brukes store menneskelige og økonomiske ressurser på granskninger, men det viser ... -
Kartlegge hva som skal til for å oppnå en CO2-nøytral fabrikk
(Master thesis, 2022)Som en følge av global oppvarming kan den økende temperaturen føre til uforutsette klimaendringer. Verdenssamfunnet har gjennom FN-initiativer avholdt globale klimakonferanser med mål om å iverksette koordinerte tiltak for ... -

Effect of annealing on the electrical resistivity of Kondo lattice CeRh2Ga2
(Peer reviewed; Journal article, 2024-04)CeRh2Ga2, which crystallizes in CaBe2Ge2-type primitive tetragonal structure (space group P4/nmm), is known to exhibit Kondo lattice heavy fermion behavior and is proposed to be a potential candidate for Weyl-Kondo semimetal ... -
Adaptive Methods for Revenue Model learning of a Slice Broker in the Presence of Adversaries
(Peer reviewed; Journal article, 2024)In the fifth-generation (5G) of mobile networks, Multi-Access Edge Computing (MEC) refers to the deployment of computing resources closer to the end-users for improved service delivery. In the context of 5G MEC, the slice ... -
Numerical Modeling and Dynamic Analysis of Two-Rotor Floating Offshore Wind Turbines
(PhD thesis UiS;682;, Doctoral thesis, 2023)The exploitation of offshore wind in deep waters by means of floating wind turbines is steadily gaining traction as a suitable option to produce renewable energy. Among the innovative technologies recently proposed, two-rotor ... -
Impact of Mud Contamination on Performance of Granite-Based Geopolymers
(PhD Theses UiS;782, Doctoral thesis, 2024)Ensuring zonal isolation and long-term integrity are fundamental in primary cementing in the well construction phase. Successful cementing can be compromised by various factors, including contamination with drilling fluid. ... -
Shape Statistics via Skeletal Structures
(PhD thesis UiS; 781, Doctoral thesis, 2024)Statistical shape analysis has emerged as a crucial tool for medical researchers and clinicians to study medical objects such as brain subcortical structures. The insights gained from such analyses hold immense potential ... -
Contributions to Risk Analysis: Improving the understanding and characterization of risk following an uncertainty-based risk perspective
(PhD thesis UiS; 754, Doctoral thesis, 2024)The present thesis aims to contribute to the development of generic risk science knowledge by exploring how risk and related concepts are understood and characterized. The main aim is to provide a stronger and more rigorous ... -
Increased impact sensitivity in ageing high explosives; analysis of Amatol extracted from explosive remnants of war
(Peer reviewed; Journal article, 2024)Millions of tonnes of explosive remnants of war remain in nature, and the volume is continuously growing. The explosive legacy of wars represents an increasing threat to the environment and to societal safety and security. ... -
Ostwald ripening of gas bubbles in porous media: Impact of pore geometry and spatial bubble distribution
(Peer reviewed; Journal article, 2024)We study pore-scale gas bubble ripening in porous media by combining a mass transfer method based on chemical potential differences with a level-set method for updating the gas/liquid configurations. We examine the impact ... -
Utilizing multiple criteria decision-making optimization methods to machine LM25Al/VC material under electro-discharge machining processes
(Peer reviewed; Journal article, 2023)In this work, sparking electro-discharge machining (EDM) process parameters are optimized by using multiple criteria decision-making (MCDM) methods. The work piece utilized for the investigation was LM25 aluminum alloy ... -
