Global‐local fatigue assessment of an ancient riveted metallic bridge based on submodelling of the critical detail
(Journal article; Peer reviewed, 2018)Increasing traffic demands (ie, load intensity and operational life) on ancient riveted metallic bridges and the fact that these bridges were not explicitly designed against fatigue make the fatigue performance assessment ... -
Godsoverføring fra vei til sjø
(Bachelor thesis, 2022)Kystverkets, «Tilskuddsordning til nærskipsfarten», har som hensikt å gi støtte til oppstart av nye godsruter i nærskipsfarten, for å bidra til Norges målsetning om 30% godsoverføring fra vei til sjø og bane innen 2030. ... -
Gone With the Wind? Offshore Wind Data Management in the North Sea
(Master thesis, 2022)Havvind sees på som en levedyktig løsning for fornybar energiproduksjon i stor skala. Norsk økonomisk sone er et område godt egnet for flytende og bunnfaste turbiner, med gunstig vær, etterspørsel og industriell kompetanse. ... -
Governance in Public Projects: The Norwegian Case
(Chapter, 2016)This book mainly focuses on governance through the lenses of private sector organizations and projects. In this chapter, we try to supplement and contrast this perspective with a description of governance in public sector ... -
Governance of Major Public Investment Projects: In Pursuit of Relevance and Sustainability
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:15, Doctoral thesis, 2010) -
Governance regimes for large transport infrastructure investment projects: Comparative analysis of Norway and Sweden
(Journal article; Peer reviewed, 2019)The two Nordic countries Norway and Sweden have launched governance regimes for the early phases of transport infrastructure investments after experiencing frequent cost overruns and low cost-benefit ratios. This study ... -
Governance schemes for major public investment projects: A comparative study of principles and practices in six countries.
(Concept rapport;47, Book, 2016)This report compares the Norwegian scheme for quality assurance of major public projects, also referred to as the State Project Model, to similar schemes in five other OECD countries, i.e. Denmark, Sweden, the Netherlands, ... -
The government regulation and market behavior of the new energy automotive industry
(Peer reviewed; Journal article, 2019)Environmental issues and cleaner production are getting increasing attentions currently, making the clean production and sustainable consumption with low emissions significant. Traditional energy vehicles are increasingly ... -
GPS Sporing som grunnlag for ny fartsmodell for syklister: En vurdering av offentlig tilgjengelig GPS-data som grunnlag til sykkelmodellering
(Master thesis, 2014)Bruken av GPS-data i transportforskning er ikke en ny tanke, men data som ligger offentlig tilgjengelig på internett har blitt viet liten til ingen oppmerksomhet. I denne oppgaven skal en prøve å vurdere potensialet til ... -
GRACE-derived ice-mass loss spread over Greenland
(Peer reviewed; Journal article, 2015)The Gravity Recovery and Climate Experiment (GRACE) monthly satellite data is used to examine the extent and magnitude of Greenland ice sheet melting for 2003-2012. We show that the well documented Greenland ice mass loss ... -
Gradient Based Design Optimization of a Radial Inflow Turbine
(Chapter, 2020)The expander is one of the key components of an ORC as the cycle efficiency strongly depends on the expander efficiency. This paper presents a method for design optimization of a radial inflow turbine (RIT) using a mean-line ... -
Gradient-based constrained well placement optimization
(Journal article; Peer reviewed, 2018)A novel well placement gradient approximation methodology is developed based on performing finite difference approximations of augmented Lagrangian derivatives within the adjoint formulation. The methodology is efficient ... -
Gradient-based design optimization and off-design performance prediction of Rankine cycles and Radial Inflow Turbines
(Doctoral theses at NTNU;2022:147, Doctoral thesis, 2022)A major fraction of today's electricity is generated by Rankine cycle power systems utilizing the thermal energy of fossil sources such as coal and natural gas, or nuclear energy. However, the carbon content in the fossil ... -
Gradient-based design optimization of a semi-submersible floating wind turbine
(Master thesis, 2020)This work presents a linearized model of a floating wind turbine using the semi-submersible OOStar base geometry, a 10MW turbine and automation of the potential flow coefficients computation. It is associated with a design ... -
Gradient-Based Design Optimization of Fully-Flexible Floating Wind Turbines Using Modal Analysis
(Chapter, 2023)A variety of substructure concepts for floating offshore wind have been developed. Design optimization can be used to efficiently explore this design space and guide further work. Previous design optimization studies have ... -
