A weak-scatterer potential flow theory-based model for the hydroelastic analysis of offshore wind turbine substructures
(Peer reviewed; Journal article, 2021)This paper examines the hydroelastic response of a monopile structure, supporting an offshore wind turbine. A new numerical simulation tool is presented, coupling a nonlinear potential flow solver to a structural model ... -
Weakening of the cognition and height association from 1957 to 2018: Findings from four British birth cohort studies
(Peer reviewed; Journal article, 2023)Background: Taller individuals have been repeatedly found to have higher scores on cognitive assessments. Recent studies have suggested that this association can be explained by genetic factors, yet this does not preclude ... -
Weakly nonlinear broadband and multi-directional surface waves on an arbitrary depth: A framework, Stokes drift, and particle trajectories
(Peer reviewed; Journal article, 2021)Surface gravity waves in coastal waters are broadband and multi-directional, whose quadratic properties are of considerable engineering and scientific interest. Based on a Stokes expansion and an envelope-type framework, ... -
Weakly nonlinear surface waves on vertically sheared currents
(Doctoral theses at NTNU;2024:57, Doctoral thesis, 2024)Extreme waves, also known as rogue waves, have much larger heights than surrounding waves, which are of great danger to ships and coastal structures. A subsurface shear current is able to change the properties of the surface ... -
Weakly nonlinear transient waves on a shear current: ring waves and skewed Langmuir rolls
(Journal article; Peer reviewed, 2019)We investigate the weakly nonlinear dynamics of transient gravity waves at infinite depth under the influence of a shear current varying linearly with depth. The shear field makes this problem three-dimensional and rotational ... -
Weakly Supervised Framework for Aspect-Based Sentiment Analysis on Students’ Reviews of MOOCs
(Peer reviewed; Journal article, 2020)Students’ feedback is an effective mechanism that provides valuable insights about teachinglearning process. Handling opinions of students expressed in reviews is a quite labour-intensive and tedious task as it is typically ... -

Weaning preterm infants off CPAP – a single unit experience
(Master thesis, 2013)Aim: To investigate continuous positive airway pressure (CPAP) weaning in preterm infants, and whether gestational age (GA) influenced the preferred weaning method or duration of weaning. Methods: A retrospective chart ... -
Weaponized AI for cyber attacks
(Journal article; Peer reviewed, 2021)Artificial intelligence (AI)-based technologies are actively used for purposes of cyber defense. With the passage of time and with decreasing complexity in implementing AI-based solutions, the usage of AI-based technologies ... -
Wear and corrosion properties of steels used in Tunnel Boring Machines
(Master thesis, 2012)In this master thesis experiments were conducted to determine the abrasion-corrosion properties of a steel designed for TBM tunnelling. This was done by three different tests, reciprocal ball-on-plate, rubber wheel and ... -
Wear bushing for drill through subsea tree
(Master thesis, 2010)Aker Solutions AS develops and manufactures Christmas trees. A version of the Christmas tree, called Horizontal Christmas tree, makes drill through operation possible. As part of Aker Solutions AS ongoing project ... -
Wear of carbon cathode lining in aluminium electrolysis cell: The effect of rotation speed in laboratory test cell
(Master thesis, 2014)The aluminium smelters are continually trying to increase their production either by designing high amperage cells or increasing the amperage on available cell designs. The service life for aluminium reduction cells is ... -
Wear of Carbon Refractory Materials in Silicon Furnaces
(Master thesis, 2016)The goal of this thesis was to investigate the internal morphology of different types of lining prepared with different installation techniques and different binders, and to see how the internal morphology affects the ... -

Wearable motion capture for 3D games
(Master thesis, 2017)The usage of technology to provide platforms for fitness and rehabilitation for the elderly is a field that can have a great impact on society in the future. Motivation for self-care and regular use of such a platform has ... -
Wearable Sensing and Quantified-self to explain Learning Experience
(Peer reviewed; Journal article, 2022)The confluence of wearable technologies for sensing learners and the quantified-self provides a unique opportunity to understand learners’ experience in diverse learning contexts. We use data from learners using Empatica ... -
Wearable sensor and a mobile app for enhancing awareness and affecting attitudes towards light exposure in daily life
(Master thesis, 2023)Denne avhandlingen utforsker design og evaluering av en ny mobilapplikasjon rettet mot å forbedre søvnkvaliteten ved å endre atferd knyttet til lys eksponering, en primær regulator av menneskets døgnrytme. Søvnkvalitetsproblemer, ... -
Wearable technology and the cardiovascular system: the future of patient assessment
(Peer reviewed; Journal article, 2023)The past decade has seen a dramatic rise in consumer technologies able to monitor a variety of cardiovascular parameters. Such devices initially recorded markers of exercise, but now include physiological and health-care ... -
Weather affects temporal niche partitioning between moose and livestock
(Journal article; Peer reviewed, 2017)Co-existing species at the same trophic level often segregate with respect to diet, habitat use, or spatial distribution, reducing their direct competition for resources. However, temporal patterns in species-specific ...
