Window design optimization in terms of daylight and thermal comfort for a typical Norwegian residential building
(Master thesis, 2021)Vindusdesign påvirker dagslystilgjengeligheten, termisk komfort i tillegg til energibehovet til bygningen. Et uheldig vindusdesign kan medføre at et bygg går fra god til dårlig ytelse. I denne masteroppgaven er norske ... -
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 ... -
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 ... -
Wing impactor for testing of aviation masts
(Master thesis, 2016)Operations at airfields require the use of certain visual and nonvisual aids in order to operate at nearly any weather condition. Some of these, such as the approach lighting system are positioned in such a way as to present ... -
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 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 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 ... -
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 ... -
