Qualification of the hybrid metal extrusion & bonding (HYB) process for welding of aluminium offshore structures
(Journal article, 2020)In the present investigation the aptness of the HYB process for butt welding of 4mm AA6082-T6 profiles is evaluated and benchmarked against one gas metal arc (GMA) weld and one friction stir (FS) weld, representing best ... -
A qualitative study of success criteria in Norwegian agile software projects from suppliers’ perspective
(Peer reviewed; Journal article, 2016)This paper provides practical insights into the success criteria in agile projects in the Norwegian software industry. We conducted 32 interviews with practitioners working with agile projects. The findings revealed two ... -
Quality and Risk Management in Projects
(Master thesis, 2012)This master thesis main topic is Quality and risk management in projects. It is written in close collaboration with the Quality and Risk Management (QRM) department at Statoil ASA (Statoil), department unit Stjørdal. The ... -
Quality incidents in projects
(Master thesis, 2010)A quality incident is an occurrence that has a negative consequence on time, cost and quality.These incidents are important for quality management in the projects. Similar to Health,Safety and Environment Incidents (HSE ... -
Quantification of Bacterial Adhesion and Characterization of Polymeric Pristine and Modified UF Membranes
(Master thesis, 2016)Membrane filtration is an important technology that might help solving future challenges regarding the access to potable drinking water. One of the main challenges in membrane operations is biofouling. Biofouling is the ... -
Quantifying Environmental Impacts of Temporary Housing at the Urban Scale: Intersection of Vulnerability and Post-Hurricane Relief in New Orleans
(Journal article; Peer reviewed, 2019)The increasing risk and exposure of people and assets to natural hazards and disasters suggests an increasing need for temporary housing following disasters. Resilience to natural hazards is dependent on the resources ... -
Quantitative comparison of cleavage and quasi-cleavage fracture surfaces in hydrogen embrittled low-carbon steel
(Journal article; Peer reviewed, 2020)The formation mechanism of the quasi-cleavage (QC) fracture surface in hydrogen embrittled low-carbon steels is not fully understood and is, therefore, intensively debated in the literature. At present, there are two ... -
Quantitative Estimation of Precipitation from Radar Measurements: Analysis and Tool Development
(Doctoral theses at NTNU;2016:51, Doctoral thesis, 2016)Current hydrological modeling efforts in Norway usually involve hourly or daily precipitation data obtained from a network of rain gauges. There is often a mismatch between the gauge network density and the spatial scale ... -
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-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 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 ... -
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 ... -
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 ... -
RailCheck: A WSN-Based System for Condition Monitoring of Railway Infrastructure
(Chapter, 2018)Contemporary tools used to monitor railway points and crossings are ineffective. Routine inspections of these critical parts are still being performed manually by specially-trained inspectors. This creates higher expenditure ... -
