E6 Væretunnelen: Anleggstekniske utfordringer ved utvidelse til to løp
(Master thesis, 2013)Etablering av doble tunnelløp blir stadig mer aktuelt. Dette skyldes økende trafikkmengder og nye krav til trafikksikkerhet. Tunnelsikkerhetsforskriften krever for eksisterende tunneler at parallelle løp skal stå ferdige ... -
The earliest datable noctilucent cloud observation (Parma, Italy, AD 1840)
(Peer reviewed; Journal article, 2020)Noctilucent clouds (NLCs) are an uncommon phenomenon that provides information about the conditions and dynamics of the mesosphere. The first observation of NLCs was recorded in 1884/1885, following Krakatoa’s eruption in ... -
Early age autogenous shrinkage cracking risk of an ultra-high performance concrete (UHPC) wall: Modelling and experimental results
(Peer reviewed; Journal article, 2021)Ultra-High Performance Concrete (UHPC) exhibits high autogenous shrinkage (AS) which significantly increases the risk of early age cracking. To predict the risks of early age shrinkage cracking of environmentally friendly ... -
Early age crack assessment of concrete structures Experimental investigation of decisive parameters
(Doctoral theses at NTNU;NTNU, 2016:256, Doctoral thesis, 2016)Concrete in the hardening phase is subjected to volume changes caused by thermal dilation and autogenous deformation. If these volume changes are restrained they may lead to cracking and further to functionality-, durability, ... -
Early age crack assessment of concrete structures: Experimental and theoretical approaches
(Chapter, 2017)The present paper contains a brief overview of work performed within the Ph.D. thesis "Crack assessment of concrete structures: experimental investigation of decisive parameters" (2010 – 2016). The main objective of the ... -
Early age cycling in the grout connection of an offshore wind jacket structure
(Master thesis, 2020)The yearly installed percentage of offshore wind jacket substructures is rising. The most common installation method for a jacket structure nowadays starts by driving the foundation piles in the seabed through a pre-piling ... -
Early age impacts of CO2 activation on the tricalcium silicate and cement systems
(Peer reviewed; Journal article, 2022)The early-age impacts of CO2 activation (using a dose of 0.3% CO2 by weight of cement) on two binder systems (tricalcium silicate and cement) were studied, principally across the first 3 h of hydration. The investigation ... -
Early careers on ecohydraulics: challenges, opportunities and future directions
(Journal article; Peer reviewed, 2016)Early career researchers (ECRs) play a critical role in our knowledge-based society, yet they are the most vulnerable group in the scientific community. As a young, interdisciplinary science, ecohydraulics is particularly ... -
Early Contractor Involvement (ECI) Approaches for Public Project Owners
(Doctoral theses at NTNU;2019:36, Doctoral thesis, 2019)Traditional project delivery methods, including, for example, design-bid-build with unit price contracting, open bidding, and owner quality control, facilitate transparent checks and balances. One shortcoming of traditional ... -
Early contractor involvement (ECI): ways to do it in public projects
(Peer reviewed; Journal article, 2020)Purpose Early contractor involvement (ECI) faces many barriers because it differs from traditional business practices. Public owners, especially, face a major challenge because they must comply with international and ... -
Early contractor involvement approaches in public project procurement
(Journal article; Peer reviewed, 2018)Purpose Early contractor involvement (ECI) faces many barriers when it is implemented in public procurement, given that it is different from traditional business practices. Primarily, public owners face a major challenge, ... -
Early Contractor Involvement: Advantages and Disadvantages for the Design Team
(Master thesis, 2014)Mange hevder at stor avstand mellom prosjekterende og utførende i byggenæringen er en kritisk hemsko for effektiv prosjektgjennomføring. Uavhengig av avstanden og årsakene er det grunn til å tro at en bedre samhandling ... -
Early decision making tools in selecting renewable energy solutions for Zero Emission Buildings (ZEB)
(Master thesis, 2011)The current residential building stock in Norway is organized in to groups, and sorted after number of building units. The criteria used for sorting, are criteria that affect the viability and rationality of various energy ... -
Early Detection of Subsurface Cracks in Rolling Element Bearings using the Acoustic Emission Time Series
(Master thesis, 2021)The formation and propagation of rolling contact fatigue (RCF) induced subsurface cracks (SSC) in a test specimen roller have been monitored using the acoustic emission time series. The sampled acoustic emission (AE) ... -
Early Detection of Subsurface Fatigue Cracks in Rolling Element Bearings by the Knowledge-Based Analysis of Acoustic Emission
(Journal article; Peer reviewed, 2022)Aiming at early detection of subsurface cracks induced by contact fatigue in rotating machinery, the knowledge-based data analysis algorithm is proposed for health condition monitoring through the analysis of acoustic ... -
Early Fault Detection of Wind Turbine Generator and Rotor Bearings
(Master thesis, 2023)Den bærekraftige energiomstillingen er avhengig av bruk av fornybare energikilder og vindturbiner spiller en sentral rolle. Feil diagnose og prognose for større feil i vindturbiner til havs og på land, som forårsaker lang ... -
Early field planning using optimisation and considering uncertainties - Study case: Offshore deepwater field in Brazil
(Peer reviewed; Journal article, 2021)During early phases of oil field development, field planners must decide upon the optimal number of wells and optimal field plateau rate, usually by performing sensitivity studies. These design choices are then “frozen” ... -
Early History Matching of the Ivar Aasen Field
(Master thesis, 2017)Dynamic reservoir simulation models are used to better understand the reservoir and predict future reservoir performance. Once a field starts to produce, a continuous flow of dynamic data becomes available in terms of ... -
Early Holocene thinning and final demise of the Scandinavian Ice Sheet across the main drainage divide of southern Norway
(Journal article; Peer reviewed, 2023)The thinning and final decay of the Scandinavian Ice Sheet in the Gudbrandsdalen area in central southern Norway is described, based on (1) cosmogenic 10Be surface exposure dating of 25 glacially transported boulders, (2) ... -
