World Heritage and Climate Change
(Book, 2020)This is a reprint of articles from the Special Issue published online in the open access journalClimate(ISSN 2225-1154) (available at: https://www.mdpi.com/journal/climate/specialissues/worldheritage) -
Wrinkling of soft bilayers created with additive manufacturing: Experimental tests, finite element modelling and analytical validation
(Peer reviewed; Journal article, 2023)In the leather manufacturing industry, the necessity to introduce new leather-surrogate materials is motivated by the huge environmental footprint of the leather production process. In fact, tanning requires a lot of ... -
Wrinkling of Soft Membrane created with Additive Manufacturing: Finite Element Modelling and Analytical validation of existing research
(Master thesis, 2023)In the leather manufacturing industry, the necessity to introduce new leather-surrogate materials is motivated by the huge environmental footprint of the leather production process. In fact, tanning requires a lot of ... -
Wrist ballistocardiography and invasively recorded blood pressure in healthy volunteers during reclining bike exercise
(Peer reviewed; Journal article, 2023)Objective: Ballistocardiogram (BCG) features are of interest in wearable cardiovascular monitoring of cardiac performance. We assess feasibility of wrist acceleration BCG during exercise for estimating pulse transit time ... -
X-ray computed tomography investigation of dilation of mineral-filled PVC under monotonic loading
(Peer reviewed; Journal article, 2019)The deformation-induced dilation of mineral-filled polyvinyl chloride (PVC) is investigated by means of polychromatic X-ray absorption tomography (XCT). Axisymmetric notched tensile specimens are strained to prescribed ... -
An X-ray micro-tomographic study of the pore space, permeability and percolation threshold of young sea ice
(Journal article; Peer reviewed, 2021) -
X-ray Microprobe Investigation of Iron During a Simulated Silicon Feedstock Extraction Process
(Peer reviewed; Journal article, 2016)Elemental silicon is extracted through carbothermic reduction from silicon-bearing raw feedstock materials such as quartz and quartzites. We investigate the micron-scale distribution and valence state of iron, a deleterious ... -
X65 steel pipes subjected to combined stretching and bending
(Chapter, 2015)Subsea pipelines are occasionally struck and hooked by objects such as anchors or trawl gear. The initial denting followed by a potential hooking and displacement of the pipeline, with a simultaneous increase in tensile ... -
XMT interface to Electrical Submersible Pump System
(Master thesis, 2010)Oil is a non renewable source of energy, and with fewer discoveries of new oil fields it is in the interest to the society to utilize the existing fields to the maximum. There are many techniques to improve the recovery ... -
YAML Based Input File Format For Finite Element Analysis
(Master thesis, 2019)Elementmetoden kan brukes til å utføre datasimuleringer (FEA) av fysiske fenomener og er mye brukt innen konstruksjon og maskinteknikk. Siden FEA innebærer arbeidskrevende beregninger utføres det best av en datamaskin, ... -
Yaw misalignment in powertrain degradation modeling for wind farm control in curtailed conditions
(Peer reviewed; Journal article, 2024)A framework characterizing the degradation of wind turbines for use in multiple-input damage-aware farm control is suggested. The focus is on the fatigue damage of the powertrain (drivetrain + generator) system, but the ... -
Yaw-effekter på vindturbiner
(Master thesis, 2010)En vindturbin med skjev innstrømning er behandlet ved hjelp av bladelementmetoden. Det har vist seg av metoden kan, ved hjelp av noen modifiseringer, også kan benyttes for å regne på vindturbiner med skjev innstrømning. ... -
Yield improvements in anaerobic digestion of lignocellulosic feedstocks
(Peer reviewed; Journal article, 2020)The new EU bioenergy sustainability criteria demonstrate that bioenergy sustainability can be a challenge (Schlegel and Kaphengst, 2007). In 1990s, the energy crops were the main source for biogas production in Europa; ... -
