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 ... -
Quo vadis artificial intelligence?
(Peer reviewed; Journal article, 2022)The study of artificial intelligence (AI) has been a continuous endeavor of scientists and engineers for over 65 years. The simple contention is that human-created machines can do more than just labor-intensive work; they ... -
R/V Gunnerus Digital Twin Infrastructure
(Master thesis, 2020)Denne rapporten undersøker potensialet for bruk av digitale tvillinger i utdannings-øyemed for ingeniørstudenter gjennom NTNUs forskningsfartøy FF Gunnerus. Samtidig som digitale tvillinger blir mer og mer relevant for å ... -
R744 ejector technology future perspectives
(Journal article; Peer reviewed, 2016)Carbon Dioxide, CO2 (R744) was one of the first commonly applied working fluids in the infancy of refrigeration more than 100 years ago. In contrast to ammonia it mainly disappeared after the first generation of synthetic ... -
