A quantitative study of salinity effect on water diffusion in n-alkane phases: from pore-scale experiments to molecular dynamic simulation
(Peer reviewed; Journal article, 2022)Numerous mechanisms have been proposed to untangle the effect of a low concentration of dissolved salts in the water flooding medium. One potential mechanism for enhanced oil movement is proposed with osmosis effect, ... -
Quantitative time lapse seismic analysis - rock physics, repeatability and inversion aspects
(Doctoral thesis at NTNU;2015:127, Doctoral thesis, 2015)Quantitative prediction of pressure as well as saturation effects from time-lapse seismic data is one of the topics of interest for geophysical society since the last decade. Time-lapse amplitude variation with offset ... -
Quantm som erstatning for tradisjonelle linjevalgsmetoder
(Master thesis, 2021)Quantm er et digitalt prosjekteringsverktøy fra teknologiselskapet Trimble som i de siste årene har fått mer og mer oppmerksomhet. Programmet skal angivelig gjøre valg og vurderinger av linjeføringer mer effektivt og ... -
Quartz Fine Particle Processing: Hydrophobic Aggregation by Shear Flocculation
(Peer reviewed; Journal article, 2023)This study investigates the hydrophobic aggregation of fine quartz particles through shear flocculation induced by dodecylamine in aqueous solutions. The effect of stirring speed, collector concentration, flocculation time, ... -
Quasi-cleavage hydrogen-assisted cracking path investigation by fractographic and side surface observations
(Journal article; Peer reviewed, 2019)Despite recent substantial advances in understanding of hydrogen embrittlement (HE), many important aspects of this widespread phenomenon remain a subject of debates. Particularly, remarkably different opinions have been ... -
Quasi-dynamic modelling of shared mooring lines for floating wind turbines
(Master thesis, 2022)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that ... -
Quasi-static Analyses of Slender Structures with Complex Cross-Sections using Explicit FEM Codes
(Master thesis, 2013)It has previously been done analyses to find global stiffness values of an umbilical cable, with mixed results or no results at all when subjected to bending. There have also been difficulties in finding a distinct stick-slip ... -
Quasi-static and dynamic behaviour of fillet welded connections
(Master thesis, 2016)Introduction Understanding the behaviour of the joints in a construction is crucial for structural engineers. In fact, the behaviour of steel joints exposed to static loading is well documented. Steel joints exposed to ... -
Quasi-static and dynamic indentation of offshore pipelines with and without multi-layer polymeric coating
(Journal article; Peer reviewed, 2018)Offshore pipelines are occasionally subjected to accidental impact loads from trawl gear or anchors, which may damage the pipe. In this study, a series of indentation experiments carried out on offshore steel pipes covered ... -
Quasi-Static and Dynamic Testing of Annealed Float Glass
(Journal article; Peer reviewed, 2018)Three different experimental set-ups were employed in the investigation of the fracture strength of annealed float glass. These included four-point bending tests on three different specimen sizes, and quasi-static and ... -
Quasi-static behavior of 3D printed lattice structures of various scales
(Peer reviewed; Journal article, 2021)Additive manufacturing technology has been playing an important role in industrial applications due to the potential capacities to fabricate complex geometries such as lattice structures, which are treated as outstanding ... -
Quasi-static behaviour of crash components with steel skins and polymer foam cores
(Journal article; Peer reviewed, 2018)Different types of crash components are extensively used by the automotive industry to absorb energy during car accidents. Such components typically consist of sandwich structures with thin metal or composite plates as ... -
Quasi-static compression and compression–compression fatigue behavior of regular and irregular cellular biomaterials
(Peer reviewed; Journal article, 2021)The main aim of the current study is to evaluate the compressive quasi-static and fatigue properties of titanium alloy (Ti6Al4V) cellular materials, with different topologies, manufactured via laser powder bed fusion (LPBF) ... -
Quasicontinuum modeling of fracture in bcc materials
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:333, Doctoral thesis, 2012)In this thesis fracture of the bcc materials iron and tungsten has been studied through multiscale simulations. The quasicontinuum (QC) method with embedded atom method (EAM) interatomic potentials are employed. The results ... -
Quaternary geological Mapping of Fennoscandia and Nordland: Deglaciation, Deposits, Stratigraphy and Applications
(Dr. ingeniøravhandling, 0809-103X; 2003:40, Doctoral thesis, 2003)Quaternary geological mapping is performed by geological surveys in most countries. At the Geological Survey of Norway (NGU), mapping of the surficial deposits has been one of the main tasks from the establishment of the ... -
Quaternions and Dual Quaternions for State and Parameter Estimation
(Doctoral theses at NTNU;2020:75, Doctoral thesis, 2020)This thesis presents new results on the use of quaternions and dual quaternions for the estimation of position and orientation using cameras and inertial sensors. The unit quaternion is a four-parameter representation of ... -
The Quest for a Precise Geoidal Height Model
(Peer reviewed; Journal article, 2004)The geoid is defined as an equipotential surface of the Earth�s actual gravity field inside the topographical masses on land (in most cases) and more or less coinciding with mean sea level at sea. Over the last decade, ... -
Quick clay monitoring using distributed acoustic sensing: A case study from Rissa, Norway
(Peer reviewed; Journal article, 2023)Quick clay avalanche is one of the most devastating landslide types worldwide. Hence, an early warning system is in demand to mitigate the fatal consequences caused by such events. To address this, distributed acoustic ... -
Quick-clay landslide mitigation using potassium chloride
(Doctoral theses at NTNU;2017:234, Doctoral thesis, 2017)Highly sensitive postglacial marine clays, termed quick clays, represent a risk for large retrogressive or progressive landslides such as the well-documented Rissa quick-clay landslide in 1978. Landslide susceptibility ...
