Kostnadsstyrt prosjekterings påvirkning på verdiskaping i byggeprosjekter
(Master thesis, 2019)Masteroppgaven vurderer hvordan kostnadsstyrt prosjektering påvirker verdiskaping i byggeprosjekter, samtidig som kostnadsrammene overholdes. Kostnadsstyrt prosjektering er ikke definert i den undersøkte litteraturen. For ... -
A generic approach to analysing failures in human – System interaction in autonomy
(Peer reviewed; Journal article, 2020)Autonomous systems operation will in the foreseeable future rely on the interaction between software, hardware and humans. Efficient interaction and communication between these agents are crucial for safe operation. ... -
Fracture Assessment of Quasi-brittle Rock Simulated by Modified Discrete Element Method
(Journal article; Peer reviewed, 2020)New developments of an in-house hybrid code, named Modified Discrete Element Method (MDEM) are presented in the paper. The new developments are on the treatment of pre-existing and propagating fractures in quasi-brittle ... -
The risk of individual fish being captured multiple times in a catch and release fishery
(Peer reviewed; Journal article, 2019)The proportion of angled Atlantic salmon Salmo salar L. being caught and released has increased. If individuals are repeatedly captured, this may have fish welfare consequences. Of 995 Atlantic salmon tagged during catch ... -
Smart Production Planning and Control: Concept, Use-Cases and Sustainability Implications
(Journal article; Peer reviewed, 2020)Many companies are struggling to manage their production systems due to increasing market uncertainty. While emerging ‘smart’ technologies such as the internet of things, machine learning, and cloud computing have been ... -
Experimental and numerical icing penalties of an S826 airfoil at low Reynolds numbers
(Peer reviewed; Journal article, 2020)Most icing research focuses on the high Reynolds number regime and manned aviation. Information on icing at low Reynolds numbers, as it is encountered by wind turbines and unmanned aerial vehicles, is less available, and ... -
The significant impact of ribs and small-scale roughness on cylinder drag crisis
(Peer reviewed; Journal article, 2020)The impact of flow-normal ribs and small-scale surface roughness on the drag and vortex shedding of a circular cylinder was investigated. Three rib heights, four relative rib spacings and three different forms of microroughness ... -

Effects of Morphology and Temperature on the Tensile Characteristics of Carbon Nitride Nanothreads
(Journal article; Peer reviewed, 2020)Very recently synthesized carbon nitride nanothreads (CNNTs) by compressing crystalline pyridine show outperformance in chemical and physical properties over diamond nanothreads. Here, using first-principle based ReaxFF ... -
A Study on the Layout of Outfitting Shipyards: Challenges and Recommendations
(Master thesis, 2020)Skipsbygging er en veldig viktig næring i Norge og er en del av den norske maritime klyngen. Norske verft har et rykte på seg for å bygge teknologisk avanserte skip som er omfattende utrustede. På grunn av global konkurranse ... -
Cross-contamination effect on turbulence spectra from Doppler beam swinging wind lidar
(Peer reviewed; Journal article, 2020)Turbulence velocity spectra are of high importance for the estimation of loads on wind turbines and other built structures, as well as for fitting measured turbulence values to turbulence models. Spectra generated from ... -
Exploring the Influence of Pre/Post-Aging on Springback in Al-Mg-Si Alloy Tube Bending
(Peer reviewed; Journal article, 2020)Aluminium alloy (Al-alloy) bent tube is one kind of strategic lightweighting components, which attracts application in industrial clusters, such as automobile, aerospace, etc. To meet the demands on high-precision ... -
IFC Schemas in ISO/TC 211 Compliant UML for Improved Interoperability between BIM and GIS
