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
(Journal article; Peer reviewed, 2015)Monitoring, assessment and prediction of service life of materials are a serious challenge for the building and construction sector. According to ISO 15686 (2008), laboratory testing must be performed alongside field testing ... -
