Load analysis on an offshore wind turbine structure
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This report is written as documentation of a master thesis in the course constructions and materials at the University of Stavanger. The thesis was performed within January to June 2012 as a further research on an international ... -
Load capacity and structural response of CLT-concrete composite slabs with two different types of shear fasteners
(Master thesis, 2021)Abstract The subject of this Master thesis is to investigate the performance of the behaviour of Cross Laminated Timber-concrete composite slabs with two different types of shear fasteners by performing theoretical predictions ... -
Load mitigation method for wind turbines during emergency shutdowns
(Peer reviewed; Journal article, 2021-02)Wind turbines experience countless shutdowns during their lifetimes. A shutdown is a transient process characterised by a pitch-to-feather manoeuvre of three blades. Such a pitch manoeuvre is often collective, open-loop, ... -
Load sequence effects and mixed-mode fatigue crack growth in offshore structures
(PhD thesis UiS;, Doctoral thesis, 2019-12)An increasing number of the offshore structures in the North Sea are being operated in a life extension phase, which means that their original design life has been exceeded. As the structures age, they are deteriorating, ... -
Local joint flexibility of tubular offshore joints with eccentric brace to chord connections
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-30)Local joint flexibility of tubular offshore joints has been researched to be able to account for correct deflection and redistribution of member forces and moments. This has shown to improve design life prediction for ... -
Log typing and electro-facies interpretation in Ekofisk field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Recognition of the dense zones in Ekofisk field is clearly observed from well logging through a specific peak in the neutron-density log. These zones appear to be intercalated in porous clean chalks in the middle part of ... -
Log-density gradient covariance and automatic metric tensors for Riemann manifold Monte Carlo methods
(Peer reviewed; Journal article, 2023)A metric tensor for Riemann manifold Monte Carlo particularly suited for nonlinear Bayesian hierarchical models is proposed. The metric tensor is built from symmetric positive semidefinite log-density gradient covariance ... -
Lokal håndtering av vannrisiko i rurale Uganda
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020)Vannkriser og mangel på vannsikkerhet er blant de største risikoene i verden. Selv om denne globale utfordringen har internasjonale avtaler og initiativer som del av løsningen, håndteres vannsikkerhetsutfordringer i stor ... -
Lokal trendestimering av Covid-19-smitte ved bayesiansk analyse
(Bachelor thesis, 2021)Dette studiet tar for seg trendmodellen for Covid-19-smitte publisert i Stavanger Aftenblad. Hensikten er å videreformidle trendmodellens bayesianske bakteppe og fremheve bayesiansk analyse som metode for estimering under ... -
Lokalisering av type-skilt i anleggsbilder
(Masteroppgave/UIS-TN-IDE/2012;, Master thesis, 2012)Denne rapporten tar for seg en algoritme som automatisk lokaliserer type-skilt i anleggsbilder. Den store variasjonen i struktur, størrelse, form, farger, bakgrunner og vinkel bilder er tatt fra har gjort oppgaven ... -
Lokalsenter- og knutepunktutvikling: En mulighetsstudie av Ganddal
(Master thesis, 2021)Oppgaven handler om lokalsenter- og knutepunktutvikling på Ganddal, som er en bydel i Sandnes kommune. Bydelen mangler et tydelig sentrumsområde, og gjennom en mulighetsstudie er det utforsket hvordan et lokalsenter på ... -

Long term analyses of wave characteristics
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)The focus in this master’s thesis was to describe and compare the two long-term analysis methods: All Sea States and Peak-Over-Threshold. Both methods are equitable and commonly approved methods to estimate extreme waves. ... -
Long Term Response Analyses of a Jacket Structure with Focus on a Peak Over Threshold Approach
(Master thesis, 2022)This thesis investigates the use of long term analysis to estimate the q-probability responses of a non-linear problem. The structure subjected to the investigations is a realistic jacket found in the Norwegian Continental ... -
Long-term health follow up of divers: the safety barriers
(Masteroppgave/UIS-TN-IØRP/2012;, Master thesis, 2012)The long-term health effects of petroleum related diving activities have been much debated in recent years. The case of the pioneer-divers has been well documented and as the use of divers continues to be a requirement in ... -
Long-term operation of an anaerobic bioreactor effluent gravity driven membrane system
(Master thesis, 2023)Currently, anaerobic treatment technology stands out as a viable solution for wastewater treatment due to its minimal carbon footprint. The key advantage lies in its capacity to directly convert organics into methane, ... -
Long-term response of a curved floating bridge to inhomogeneous wind fields
(Peer reviewed; Journal article, 2023-07)A numerical model of a 5 km long curved floating bridge, planned for the Bjørnafjord, in Norway, is subjected to strong wind events with stationary mean properties that vary along the bridge axis. A Weather Research and ... -
Loss of Integrity on Mooring Lines – Causes and Consequences
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-16)In the history of offshore industry, position keeping has been an essential part for allowing operations to be performed, and production to be maintained. This is often done by connecting mooring lines between the vessel ... -
Loss of LEUCINE CARBOXYL METHYLTRANSFERASE 1 interferes with metal homeostasis in Arabidopsis and enhances susceptibility to environmental stresses
(Peer reviewed; Journal article, 2022)The biochemical function of LEUCINE CARBOXYL METHYLTRANSFERASE 1 (LCMT1) is to transfer a methyl group from the methyl donor S-adenosylmethionine (SAM) to the catalytic subunits of PROTEIN PHOSPHATASE 2A (PP2Ac), PP4 and ... -
