3D in vitro cancer models for drug screening: A study of glucose metabolism and drug response in 2D and 3D culture models
(PhD thesis UiS;, Doctoral thesis, 2022-03)Current drug screening protocols use in vitro cancer cell panels grown in 2D to evaluate drug response and select the most promising candidates for further in vivo testing. Most drug candidates fail at this stage, not ... -
A novel approach to surfactant flooding under mixed-wet conditions
(PhD thesis UiS;202, Doctoral thesis, 2013-09-13)In early days, a large number of research studies have been done based on the assumption that most of the sandstone reservoirs are strongly water-wet. Now it is widely accepted that most of sandstone reservoirs are at ... -
Activity-based life-cycle cost analysis : design, operation and maintenance in Arctic environment
(PhD thesis UiS;134, Doctoral thesis, 2011-08-25)Currently the oil and gas exploration and production is moving north towards the Barents Sea on the northern coast of Norway, north of the Arctic Circle. This unfamiliar operational environment of the Arctic poses new ... -
Adjoint-state method for seismic AVO inversion and time-lapse monitoring
(PhD thesis UiS;, Doctoral thesis, 2023)This dissertation presents seismic amplitude versus offset (AVO) inversion methods to estimate water saturation and effective pressure quantitatively in elastic and viscoelastic media. Quantitative knowledge of the saturation ... -
Aerodynamic loads on a wind turbine rotor in axial motion
(PhD thesis UiS;245, Doctoral thesis, 2015-03-13)This study investigates the unsteady aerodynamics of attached flow on a two-dimensional airfoil. The unsteady aerodynamics introduces aerodynamic damping of the offshore wind turbine structure and is thus important for ... -
Analysis and Management of Bottlenecks in Supply Networks : Towards a Structured Approach to Stabilization of Inbound Material Flow
(PhD thesis UiS;256, Doctoral thesis, 2015-06-11)Any organization whose business model is based on production relies, and is dependent, on providers of raw material which it transforms into products. Customers’ demand for products, and thus the producing firm’s demand ... -
An analysis of commodity price dynamics with focus on the price of salmon
(PhD thesis UiS; 99, Doctoral thesis, 2010-06-04)This thesis is concerned with studying the short run dynamics of commodity prices. The industry of interest and primary study is Norwegian Aquaculture, with the price of farmed salmon as the main data-set. Even though ... -
An Analysis of Temporal and Spectral Connectedness and Spillover in Commodity Markets
(PhD thesis UiS;457, Doctoral thesis, 2020-05)This thesis is concerned with evaluating the temporal and spectral connectedness and spillover dynamics of commodity prices. The industries of interest are crude oil, agricultural commodities, aquaculture, and Norwegian ... -
Asset Integrity Management : Challenges, planning and implementations
(PhD thesis UiS;306, Doctoral thesis, 2016-08-23)The emergence of asset integrity management (ATM) in the petroleum industry has been encouraged by the demand for a safer and more sustainable workplace with respect to health, safety, environment, value generation and ... -
Automated Grading of Bladder Cancer using Deep Learning
(PhD thesis UiS;, Doctoral thesis, 2022-02)Urothelial carcinoma is the most common type of bladder cancer and is among the cancer types with the highest recurrence rate and lifetime treatment cost per patient. Diagnosed patients are stratified into risk groups, ... -
Automatic AI-Driven segmentation of Acute Ischemic Stroke Regions with CT Perfusion Images
(PhD thesis UiS;, Doctoral thesis, 2023)This thesis investigates artificial intelligence (AI) methodologies to automatically delineate ischemic areas of brain Computed Tomography Perfusion (CTP) scans acquired at hospital admission in patients suspected of acute ... -
Automatic Video Analysis in Resuscitation
(PhD thesis UiS;, Doctoral thesis, 2020-01)This thesis investigates possibilities for applying automatic video analysis in the medical context of resuscitation of a patient. Two situations are investigated: 1) Out-of-hospital cardiac arrest (OHCA) where there is a ... -
Better prognostic markers for nonmuscle invasive papillary urothelial carcinomas
(PhD thesis UiS;, Doctoral thesis, 2022-04)Bladder cancer is a common type of cancer, especially among men in developed countries. Most cancers in the urinary bladder are papillary urothelial carcinomas. They are characterized by a high recurrence frequency (up to ... -
Blockchain based energy transactions for a prosumer community
(PhD thesis UiS;, Doctoral thesis, 2021-09)Integration of solar micro-generation capabilities in domestic contexts is on the rise, leading to the creation of prosumer communities who generate part of the energy they consume. Prosumer communities require a decentralized, ... -
Bridge aerodynamics in skew winds: Generalized buffeting load modelling and response analysis
(PhD thesis UiS;, Doctoral thesis, 2022-11)This thesis deals with the modelling of wind loads on bridges. When turbulent wind blows past a bridge deck, the deck experiences fluctuating loads, i.e., buffeting loads. Most buffeting theories concern straight bridge ... -
Bridge deck aerodynamics: A case study in full-scale
(PhD thesis UiS;, Doctoral thesis, 2022-04)One of the key aspects of bridge deck aerodynamics is the transformation of the incident wind flow into fluctuating surface pressures around a bridge deck. The atmospheric turbulence generates fluctuating loads on bridge ... -
Bridgeland Stability Conditions and the Hilbert Scheme of Skew Lines in Projective Space
(PhD thesis UiS;, Doctoral thesis, 2023-03)Bridgeland stability conditions are powerful tools for studying derived categories, with several applications to algebraic geometry. They were introduced by Bridgeland in 2002 [Bri07], who was motivated by Douglas’ work ... -
