Investigation of Stuck Pipe Incident KH-1 Slaovakia 2013: Root Cause Analysis
(Master thesis, 2014)Stuck pipe incidents are a major operational concern during most drilling operations. Even when stuck pipe situations are resolved, they usually require a lot of resources. In the worst case scenario stuck pipe causes loss ... -
Investigation of sub-micron particles and their impact on membrane fouling in drinking water treatment
(Master thesis, 2010)The drinking water industry is gaining more interest in substituting conventional separation technologies for treatment of surface waters with membranes due to their separation capabilities. Low pressure membranes are ... -
Investigation of suction capability of a centrifugal pump impeller
(Master thesis, 2021)Sentrifugalpumper er en turbomaskin, hvor løpehjulet øker trykket i væsken. Den første kjente prototypen for en sentrifugalpumpe eksisterte allerede på 1400-tallet. Det har vært en konstant utvikling fra den første kjente ... -
Investigation of tension in anchor lines and influence on vessel behaviour. Time domain simulation of Barge response.
(Master thesis, 2016)The topic of this thesis is time domain analysis of mooring line effects on a vessels response, where a barge is used as test model. This type of simulation can be used to investigate and evaluate how the forces from the ... -
Investigation of terrain effects with respect to wind farm siting
(Doctoral Theses at NTNU, 1503-8181; 2009:199, Doctoral thesis, 2009)The turbulent flow above complex and generic terrain has been investigated in a wind tunnel. The objective was to generate a test case for numerical models, and to investigate flow above complex terrain with a view to wind ... -
Investigation of the adsorption and biodegradation capacity of filter media towards airport de-icing chemicals
(Master thesis, 2016)At airports in Norway, propylene glycol (PG) and potassium formate (PF) are used as de-icing chemicals to provide safe air traffic. Expected climate changes will lead to temperatures more frequently around zero degrees, ... -

An investigation of the anisotropic properties of heat-treated maraging steel grade 300 processed by laser powder bed fusion
(Peer reviewed; Journal article, 2021)In order to explore the possibilities enabled by laser beam powder bed fusion of metals (PBF-LB/M), reliable material models are necessary to optimize designs with respect to weight and stiffness. Due to the unique processing ... -
Investigation of the Burridge-Knopoff-Pad model with a focus on eigenmodes and Rayleigh Damping
(Master thesis, 2021)Burridge-Knopoff-Pad-modellen er en nyutviklet og lite studert modell laget for å representere den skjærende lyden fra bilbremser grunnet friksjonsinduserte vibrasjoner. Modellen kombinerer Burridge-Knopoff-modellen som ... -
Investigation of the change in soil fabric during cone penetration in silt using 2D measurements
(Journal article; Peer reviewed, 2017)Interpretation of CPTU testing in silt is non-trivial because of the partially drained conditions that are likely to occur during penetration. A better understanding of the pore pressure generation/dissipation is needed ... -
Investigation of the Consequences of Buy-Back Agreements in the Norwegian Snacks and Confectionery Supply Chain
(Master thesis, 2019)Tilbakekjøpsavtalen i nøtte- og sukkervare verdikjeden er et resultat av maktfordelingen innen verdikjeden. Avtalen innebærer at produsenten kan øke etterspørselen av produktene deres ved å stimulere salginitiativ i de ... -
Investigation of the effect of indoor environment on hypothermia and energy consumption in operating rooms
(Master thesis, 2021)Årlig får rundt 3.1% av pasienter ved norske sykehus infeksjoner som oppstår i forbindelse med operasjoner (SSI) (St.Olavs, 2019). Flere faktorer vil forebygge infeksjoner, men det er essensielt å holde pasienten i normotermi ... -
