A bottom-fixed lattice tower for offshore wind turbines
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:160, Doctoral thesis, 2014)Wind turbines have been sited away from coasts in the last decade to exploit the tremendous potential of wind energy on the vast oceans, especially in Northern Europe where there is relatively limited space on land and ... -
A cloud-based pipeline for Event Sourcing of geospatial data
(Master thesis, 2020)Mange geografiske datasett blir oppdatert samlet, med jevnlig publisert av fullverdige, nye versjoner. For en del applikasjoner er imidlertid det historiske perspektivet og endringen av data mellom versjoner viktig informasjon ... -
A Combined Breakwaters System: A Wave Attenuation Study on the Combination of Submerged and Floating Breakwaters using REEF3D
(Master thesis, 2019)Coastal zones have been a dynamic area and most favoured locations utilized for living, leisure, recreational activities, tourism, commerce and many other human ac- activities. Submerged and floating breakwaters have been ... -
A Combined Level Set/Ghost Cell Immersed Boundary Representation for Simulations of Floating Bodies
(Journal article; Peer reviewed, 2016)A six degrees of freedom (6DOF) algorithm is implemented in the open-source CFD code REEF3D. The model solves the incompressible Navier–Stokes equations. Complex free surface dynamics are modeled with the level set method ... -
A comparative analysis of the fluid-structure interaction method and the constant added mass method for ice-structure collisions
(Journal article, 2016)The constant added mass (CAM) method and the fluid-structure interaction (FSI) method are widely used to simulate ship-ship and ship-ice collisions. In the CAM method, the hydrodynamic effect of the surrounding water is ... -
A comparative case study of Public-Private Partnerships in road infrastructure projects: Spain and Norway
(Master thesis, 2015)Public-Private Partnership scheme in infrastructures is not a new concept that has come up in the last years; this is a strategy that has evolved adapting to the new necessities and requirements of the society. Over the ... -
A Comparative Study on Hospital Construction Cost Between Norway and The United States - Based on case studies
(Master thesis, 2017)Within the construction industry, there have been many attempts to identify the cost factors or to compare the building costs. However, it seems the combination of both has not been applied so much especially in healthcare ... -
A Comparison of Competitive Dialogue and Best Value Procurement
(Chapter, 2018)Competitive Dialogue (CD) and Best Value Procurement (BVP) are two different approaches to early contractor involvement (ECI) in public projects. However, it is not clear which approach is best suited for what kind of ... -
A Comparison of Direct Membrane Filtration and Moving Bed Biofilm Reactor for Municipal Wastewater Treatment in Norway
(Master thesis, 2020)Med et økende fokus på miljø og bærekraft, bør også infrastruktur som avløpsrensing rustes for fremtiden, med vekt på kompakthet, lavt karbonfotavtrykk og potensiale for energigjenvinning. To konsepter som kan vurderes i ... -
A comparison of friction piles bearing capacity based on theoretical and empirical mathematical models
(Master thesis, 2012)This thesis consists of 8 chapters and each chapter is described as follows:Chapter 2: Presents the different types of piles which exist today and their classification.Chapter 3: Presents the different soil parameters we ... -
A Comparison of Railway Load Models for Geotechnical Analysis
(Master thesis, 2018)Bane NOR is responsible for developing the railway network in Norway. In Norway, the Eurocodes are specifying how structural design in general should be conducted. This also applies to the railways. To guide those responsible ... -
A comparison of the energy market in Scandinavia and in Nigeria and the role of framework for Independent Hydropower Producers
(Master thesis, 2020)Hydropower optimization could aid in minimizing resource input for electricity generation and overall system operations cost. This study used the EMPS modelling to analyze the performance of Nigeria’s large hydropower ... -
A Comparison of Theoretical and Measured Pressure Losses Within a Drinking Water Treatment Plant
(Master thesis, 2016)Pressure loss and its effects on the resulting hydraulics within a drinking water treatment plant are extremely important aspects of design and operation. Pressure losses are important to monitor as they are the driving ... -
A comparison of wave generation methods simulating extreme waves in a numerical wave tank
(Chapter, 2017)Extreme wave conditions emanate from the random and instantaneous interaction of waves during storm events. These wave conditions may cause potentially severe damage to ships and offshore oil and gas structures. There are ... -
A Contractor's Experience of a Best Value Approach Project in Norway
(Master thesis, 2018)Most road construction projects in Norway use the Design-Bid-Build delivery method. In the Design-Bid-Build method the project owner goes into contract with a project designer that designs the project, before interested ... -
A cost-effective approach to predict dynamic variation of mesohabitats at the river scale in Norwegian systems
(Journal article; Peer reviewed, 2014)This paper presents a cost-effective approach to predict dynamic variation of mesohabitat classes or hydromorphological units (HMUs) in the context of a peaking scenario. Predicting dynamic mesohabitats has been a challenge ... -
A coupled modeling of design and investment parameters for optimal operation of methane bioreactors: Attainable region concept approach
(Journal article; Peer reviewed, 2020)Current practice to design methane bioreactors does not consider all degrees of freedom simultaneously, which raises question of global optimality. This study presents a model-based design framework, which simultaneously ... -
