Investigation of the microstructure evolution and deformation mechanisms of a Mg-Zn-Zr-RE twin-roll-cast magnesium sheet by in-situ experimental techniques
(Journal article; Peer reviewed, 2018)Twin roll casting (TRC), with a relatively fast solidification rate, is an excellent production method with promising potential for producing wrought semi or final Mg alloy products that can often suffer from poor formability. ... -
Investigation of Vision Transformers for Visual Place Recognition
(Master thesis, 2021)Fremskritt innen autonom robotikk kan ha store konsekvenser for samfunnet som helhet i fremtiden. Et av de største hindrene som forhindrer virkelig autonome roboter er utfordringen med å skulle kunne sikkert lokalisere seg ... -
Investigation on the plastic zone during crack growth experiments in high-alloy CrMnNi TRIP/TWIP steels by means of the complementary in situ characterization techniques: digital image correlation, infrared thermography and acoustic emission measurements
(Master thesis, 2020)This thesis describes the analysis of the material behaviour of two high-alloy CrMnNi steels with TRIP and TWIP effect respectively. The focus of the investigations was the systematic characterisation of the mechanical ... -
Ion Exchange: - A Treatment Option for Acid Mine Drainage
(Master thesis, 2014)The sorption of heavy metals from Acid Mine Drainage (AMD) by using clinoptilolite, a natural zeolite, was studied in this thesis. The behavior of clinoptilolite, as an ion exchanger, was studied to see if the concentration ... -
Ionic liquid additives in water-based lubricants for bearing steel – effect of electrical conductivity and pH on surface chemistry, friction and wear
(Journal article; Peer reviewed, 2022) -
Ionic Liquids as Additives in Low Viscosity Lubricants – A Surface Adsorption and Tribofilm Study
(Doctoral theses at NTNU;2022:130, Doctoral thesis, 2022)The trend in lubrication nowadays is towards low viscosity lubricants. Low viscosity lubricants flow more easily, increasing the lubricant volume circulation thus improving the cooling performance and cleaning ability of ... -
Ionic Liquids as Additives in Water‑Based Lubricants: From Surface Adsorption to Tribofilm Formation
(Peer reviewed; Journal article, 2020)Ionic liquids (ILs) are potential lubricant additives that can potentially perform simultaneously as friction modifiers and anti-wear agents. In addition, they possess good thermal stability, they are non-flammable, they ... -
Ionic liquids as boundary additives in water-based and PAO lubricants
(Peer reviewed; Journal article, 2021)Ionic liquids have been widely discussed as potential lubricants, however, their properties make them also very good potential candidates as lubricant additives (e.g., friction modifiers and anti-wear). In this work, the ... -
IPD governance implications
(Chapter, 2019)Interest in project-management (PM) governance has grown steadily over the past decade. Turner (2006) introduced, over a decade ago, the role of governance (based on a definition of corporate governance) in the development ... -
