Finite element analysis and experimental testing of lifting capacity for GRP cover.
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)Structures made of glass reinforced plastic (GRP), often abbreviated GRP cover, are used to protect subsea equipment in the oil and gas industry. These structures need to be lifted during fabrication, transportation and ... -
Finite Element Analysis and Fatigue Damage Assessment of a Railway Bridge Subjected to Variable Amplitude Loading
(Bachelor thesis, 2023)Many of the railway bridges in Norway and the rest of the world are closing in on the end of their predicted service life, and the need for more precise fatigue life assessments and predictions is challenging for the railway ... -
Finite element analysis of a friction clamp located on a North Sea jacket
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)This master thesis is written on the University of Stavanger spring 2011 in collaboration with Subsea 7. When transporting hydrocarbons from seabed to top side on a jacket platform there is always the need of a riser. ... -
Finite Element Analysis of Steel Plates with Rectangular Openings Subjected to Axial Stress
(Peer reviewed; Journal article, 2022)Steel plates with openings are among the important ship structural components used in the ship’s hull to withstand the hydrostatic forces of the ocean, which cause sagging and hogging moments at the ship’s bottom. The ... -
Finite element method simulation and modeling of tubing wear
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)This thesis presents finite element method (FEM) based on tubing wear simulation studies. Based on wear depth observed from field data, several scenarios were simulated. These are shut-in, production and gas injection. ... -
Finite element method-based modeling of bending under tension friction test of deep drawing quality steel sheets
(Peer reviewed; Journal article, 2019)Understanding of the effect of the friction on the sheet deformation is a key factor in design and realization of stamping process. Among others, bending under tension friction test simulates the frictional phenomena on ... -
Finite Element Modelling and Analysis of Axial Settlement of Light Poles
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020)The slip joint technology is a method for connecting two conical pole segments together, without the use of bolts or grout, thus reducing time of installation and the need of maintenance. In recent years there have been ... -
Finite Element Models for Integrity Assessment of Flexible Riser with Damaged Tensile Wires
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06)Many of the flexible risers in service do not meet their documented service life. A common failure mode is the rupture of the abrasive external layer which, in itself, is not critical, but seawater ingress may corrode ... -
Finite-temperature single molecule vibrational dynamics from combined density functional tight binding extended lagrangian dynamics simulations and time series analysis
(Peer reviewed; Journal article, 2020)Combining a computationally efficient and affordable molecular dynamics approach, based on atom-centered density matrix propagation scheme, with the density functional tight binding semiempirical quantum ... -
Finnes den afrikanske middelklassen?
(Journal article, 2016-08)Verdensbankens definisjon av «middelklassen» i Afrika forvrenger vår forståelse av kontinentets økonomiske utvikling de siste årene. Ved å undersøke typiske middelklassegoder som å ha råd til mobiltelefon, bil og besøk på ... -
Finnes der en optimal størrelse på norsk petroleumsøkonomi?
(Masteroppgave/UIS-SV-HH/2014;, Master thesis, 2014-06-13)Siden det norske oljeeventyret startet med det første oljefunn på begynnelsen av 1970 –tallet har Norge vokst seg til å bli en betydelig olje- og gassprodusent internasjonalt. Betydningen petroleumssektoren har hatt for ... -
Finnes det en metode for etablering av intraossøs tilgang som er overlegen andre metoder? En sammenlikning av 3 forskjellige intraossøse verktøy
(Master thesis, 2023)Sammendrag Bakgrunn I situasjoner som omhandler akutt sykdom eller skade er tiden ofte en kritisk faktor, og det er flere tidstyver akuttmedisinsk personell må vokte seg for. Intravenøs tilgang kan både være tidkrevende ... -
Finnes det kjønnsforskjeller i viljen til å konkurrere, og kan dette forklares av overkonfidens og risikoaversjon?
(Bachelor thesis, 2023)Formålet med denne oppgaven har vært å undersøke om det finnes kjønnsforskjeller i viljen til å konkurrere, og om dette kan forklares av overkonfidens og risikoaversjon. Det er blant annet interessant å studere kjønnsforskjellene ... -

Finnes det tidsforskjeller i oppdagelse og håndtering av hjerneslag prehospitalt, og hvilke faktorer er i så fall utslagsgivende?
(Masteroppgave/UIS-HV/2020;, Master thesis, 2020-06)Sammendrag I denne masteroppgaven presenteres en blanding av en kvantitativ og en kvalitativ studie med formål om å analysere om prehospital tidsbruk varierer og en undersøkende tilnærming til hvilke faktorer som kan ... -
Firewall black holes and echoes from an action principle
(Peer reviewed; Journal article, 2023)It is often said that there is no gravity theory based on local action principles giving rise to firewall black hole solutions. Additionally, Guo and Mathur [Int. J. Mod. Phys. D 31, 2242009 (2022).] have cast doubt on the ... -
