Wind-wave directional effects on fatigue of bottom-fixed offshore wind turbine
(Journal article; Peer reviewed, 2019)The current trend for offshore wind energy is that larger turbines are placed on monopile foundations at increasing water depth. This requires larger foundations, increasing the importance of hydrodynamic loading. It is ... -
Wind-wave misalignment effects on floating wind turbines: motions and tower load effects
(Journal article; Peer reviewed, 2014)The dynamic responses of a spar, tension leg platform (TLP), and two semisubmersible floating wind turbines (FWTs) in selected misaligned wind and wave conditions are investigated using numerical simulation with an ... -
Windjammer: Finding Purpose and Meaning on a Tall Ship Adventure
(Peer reviewed; Journal article, 2023)The Windjammer project started in 2018 as a social entrepreneurship program in Norway for adolescents at risk of social drop-out and societal exclusion. While the effects on society of such programs are difficult to measure, ... -
Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality
(Peer reviewed; Journal article, 2020)Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the ... -
Window spacers and edge seals in insulating glass units: A state-of-the-art review and future perspectives
(Journal article; Peer reviewed, 2013)Insulating glass (IG) units typically consist of multiple glass panes that are sealed and held together structurally along their perimeters. This report describes a study of edge seals in IG units. First, we summarize the ... -
Window view of nature after brief exercise improves choice reaction time and heart rate restoration
(Peer reviewed; Journal article, 2020)Research indicates that natural environments induce restorative effects on cognitive capacity and autonomic arousal. The present study investigates differences in choice reaction time (CRT) and heart rate responses in ... -
Windows in the Buildings of Tomorrow; Energy Losers or Energy Gainers?
(Journal article; Peer reviewed, 2013)One of the most effective actions for reduction of energy loss through the building envelope is to optimize the thermal performance, area and localization of the transparent components in the façade in order to obtain ... -
Winds and tides in the mid-latitude southern hemisphere upper mesosphere recorded with the Falkland Islands SuperDARN radar
(Journal article; Peer reviewed, 2011)Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52 S, 59 W) are used to characterize the atmospheric tides and background winds in the upper mesosphere above the South Atlantic. ... -
Winglet optimization for a model-scale wind turbine
(Peer reviewed; Journal article, 2018)A winglet optimization method is developed and tested for a model-scale wind turbine. The best-performing winglet shape is obtained by constructing a Kriging surrogate model, which is refined using an infill criterion based ... -
“Winter is coming”: Psychological and situational factors affecting transportation mode use among university students
(Journal article; Peer reviewed, 2019)The aim of this study was to investigate the relative roles of the norm activation model (NAM), transport priorities and situational constraints (car ownership, distances, gender and age) while considering spatial heterogeneity ... -
Winter Peaks in Heart Failure: An Inevitable or Preventable Consequence of Seasonal Vulnerability?
(Peer reviewed; Journal article, 2019)Climate change is a major contributor to annual winter peaks in cardiovascular events across the globe. However, given the paradoxical observation that cardiovascular seasonality is observed in relatively mild as well as ... -
WIP: “It’s a Trap!”—How Speculation Invariance Can Be Abused with Forward Speculative Interference
(Chapter, 2021)Side-channel attacks based on speculative execution access sensitive data and use transmitters to leak such data during wrong-path execution. Speculative side-channel defenses have been proposed to prevent such information ... -
Wire and Arc Additive Manufacturing with TiC-Nanoparticle Reinforced AA5183 Alloy
(Peer reviewed; Journal article, 2020)Wire and arc additive manufacturing of aluminium-ceramic composites shows great potential to produce high strength materials. By incorporation of nanoparticles in the feedstock wire, fine-grained material with low ... -
Wire Arc Additive Manufacturing by Robot Manipulator: Towards Creating Complex Geometries
(Journal article; Peer reviewed, 2019)Additive manufacturing (AM) is the umbrella term that covers a variety of techniques that build up structures layer-by-layer as opposed to machining and other subtracting methods. It keeps evolving as an important technology ... -
Wire arc additive manufacturing of AA5183 with TiC nanoparticles
(Peer reviewed; Journal article, 2021)Aluminium alloys processed by wire arc additive manufacturing (WAAM) exhibit a relatively coarse microstructure with a columnar morphology. A powerful measure to refine the microstructure and to enhance mechanical properties ... -
Wire-arc additive manufacturing of structures with overhang: Experimental results depositing material onto fixed substrate
(Peer reviewed; Journal article, 2022)As additive manufacturing (AM) technology grows both more advanced and more available, the challenges and limitations are also made more evident. Most existing solutions for AM build structures layer by layer using strictly ... -
