(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 ... -
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 ... -
Wireless Sensor Networks for Detection and Localization of Subsea Oil Leakages
(Journal article; Peer reviewed, 2021)This work studies the impact of Wireless Sensor Networks (WSNs) for oil spill detection and localization in Subsea Production Systems. The case study is the Goliat FPSO, with a realistic assumption about the presence of a ... -
Wireless sensor system for real-time performance monitoring in sports
(Peer reviewed; Journal article, 2023)In Paralympic sports, investigating seating ergonomics and optimizing for performance is crucial due to individual impairments. Usually, experiments are conducted in laboratory environments and for skiing, usually on a ... -
Wisdom of crowds i en digital byggebransje
(Master thesis, 2023)Gode estimat er noe byggebransjen er avhengig av å gi, ettersom estimatene ofte er styrende for byggeprosjekt. For å gi estimat benyttes det i dag ulike fremsynsmetoder. Wisdom of crowds har vist seg å være en metode som ... -
Withdrawal of pairs of threaded rods with small edge distances and spacings
(Journal article, 2018)An experimental investigation on withdrawal of pairs of screwed-in threaded rods embedded in glued-laminated timber elements is presented in this paper. Specimens with varying angles between the rod axis and the grain ... -
Withdrawal Properties of Threaded Rods Embedded in Glued-Laminated Timber Elements
(Doctoral thesis at NTNU;2016:48, Doctoral thesis, 2016)The competitiveness of timber structures is largely governed by the design and effectiveness of the connections. Connections with long axially loaded self-tapping screws or threaded rods embedded with an inclination to the ... -
Within plate gabbroic intrusion at 565 Ma in the Uppermost Allochthon - A regional, geochemical and geochronological study of the Umbukta gabbro, north-central Norway
(Master thesis, 2016)A part of the Kjerringfjell Group in the Rӧdingsfjället Nappe Complex in the Uppermost Allochthon of north-central Norway was mapped during this thesis. The rocks in this area mainly compose of garnet-biotite gneiss, ... -
Wood burning habits and its effect on the electrical energy demand of a retrofitted Norwegian detached house
(Journal article; Peer reviewed, 2019)Using firewood as a space heating source is a popular solution in Norwegian housing and can significantly reduce the electrical energy demand of houses. This study analysed habits and reasons for using a wood stove from ... -
Wood coating failures against natural and accelerated climates
