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 ... -
WingTech Dashboard
(Bachelor thesis, 2019)Denne oppgaven er gitt etter ønske fra WingTech AS om å utvikle et system som kan effektivisere rapportering og visualisering av data ut til deres kunder, og samtidig kunne brukes som et internt verktøy for å optimalisere ... -
Winter gardening at 78° North: measuring extreme warm spell impacts on above- and below-ground biomass of vascular plant communities
(Master thesis, 2022)Global oppvarming gjer dei arktiske vintrane varmare og våtare, noko som fører til ei auke i ekstreme vêrfenomen på vinteren. Døme på slike vêr-hendingar er regn som frys på og dannar eit islag som «kapslar inn» tundraen ... -
“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 Modelling of Green Roofs in Cold Climates Using SWMM
(Master thesis, 2020)Grønne tak har blitt identifisert som et mulig tiltak for å redusere og forsinke avrenningen av overvann i tett utbygde byområder. Selv om det er utført omfattende arbeid for å forutsi og forbedre grønne tak sine funksjoner, ... -
Winter operations of permeable interlocking concrete pavement.
(Master thesis, 2020)Kombinasjonen av klimaforandringer og urbanisering har ført til problemer med å håndtere det økende volumet av overvann og at den maksimale vannføringen skjer tidligere. Tradisjonelt har overvann blitt ført til resipienten ... -
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 ... -
Winter Sports Tribology - An Experimental Approach To Understanding Kinetic Friction and Equipment Performance in Speed Skating
(Master thesis, 2017)Friction behaviour in the sport of speed skating has been investigated by use of a tribometer designed at NTNU. The objective was to study if the tribometer could measure relative differences within different skate blades. ... -
Winter Technologies for High Speed Rail
(Master thesis, 2011)High speed rail are operatives in many countries in the world. The technology has evolved for about 40 years now and is mastered by several worldwide companies. However, high speed rail are fairly new in Nordic countries ... -
Winter walking: The impact of pavement surface conditions on pedestrians' walking behavior during winter
(Doctoral theses at NTNU;2022:143, Doctoral thesis, 2022)Norsk sammendrag Målet med denne forskningen har vært å kvantifisere sammenhenger mellom fotgjengeres atferd (samt konsekvenser av atferd) og føreforhold om vinteren. Metodene har bestått av observasjonsstudier med ... -
Winterization of Railways - Issues and Effects
(Master thesis, 2016)Railways are an important mode of transportation all around the world. Inherent privileges of rail transportation, and increasing tendency of governments towards maximized utilization of railway systems, emphasize the ... -
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 Manufactured in the Marine Sector - A Study of WAAM and the Deposition of Marine Grade Metals
(Master thesis, 2018)Additive manufacturing has in the recent years become more accessible, and the areas of potential use have expanded. This thesis looks into the effect on two marine grade metals, Inconel 625 and Super Duplex stainless ... -
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 ... -
