Dimensjonsstabilitet til et nytt elektromagnetisk komposittmaterial til bruk i elektriske motorer
(Master thesis, 2019)I denne oppgaven studerer vi statorer til elektriske motorer laget med en ny produksjonsteknologi og disses oppførsel under termisk ekspansjon og herdekrymp. Statoren, som er den stasjonære delen i en elektrisk motor, ... -
Direct Integration of Strained-Pt Catalysts into Proton-Exchange-Membrane Fuel Cells with Atomic Layer Deposition
(Peer reviewed; Journal article, 2021)The design and fabrication of lattice-strained platinum catalysts achieved by removing a soluble core from a platinum shell synthesized via atomic layer deposition, is reported. The remarkable catalytic performance for the ... -
Directed Energy Deposition versus Wrought Ti-6Al-4V: A Comparison of Microstructure, Fatigue Behavior, and Notch Sensitivity
(Journal article; Peer reviewed, 2019)Laser Engineered Net Shaping (LENS), a Direct Energy Deposition (DED) additive manufacturing process is a 3D manufacturing process generally used to produce fully dense parts or to repair/add additional material to an ... -
Directional fatigue behaviour of maraging steel grade 300 produced by laser powder bed fusion
(Peer reviewed; Journal article, 2021)Surfaces of metals produced by additive manufacturing (AM) are known to be rough and populated with defects, this is, in particular, true for downward-facing (down-skin) surfaces. When dealing with the fatigue of as-built ... -
Directional Wells in Shallow Reservoirs using Curved Conductors and Hammering - Concept and analysis of a novel installation method for curved conductors
(Master thesis, 2015)One of the challenges encountered when planning wells in shallow reservoirs in the arctic is the development of a plan to drill a relief well. According to NORSOK such a plan is required to be in place prior to the initiation ... -
Discrete Element Modeling of FDM Printed Specimens
(Master thesis, 2021)FDM-teknologi har nylig vekket økt oppmerksomhet i industri og blant forbrukere. Det har derimot enda ikke sett utbredt bruk i strukturelle sammenhenger. I denne oppgaven testes discrete element method (DEM), som nylig har ... -
Disruption management in the airline industry
(Master thesis, 2015)The first point of the study purpose is taken into account in the second and third chapter of this work. It helps to create the ground of the successive argument and it also shows the main problem that could generate a ... -
Dissecting the project anatomy: Understanding the cost of managing construction projects
(Peer reviewed; Journal article, 2021)The total cost of a construction project involves both the cost of production and the transaction costs associated with managing the project. However, we know surprisingly little about the magnitude of transaction costs ... -
Dissolution kinetics of R-glass fibres: Influence of water acidity, temperature, and stress corrosion
(Journal article; Peer reviewed, 2019)Glass fibres slowly degrade due to dissolution when exposed to water. Such environmental aging results in the deterioration of the mechanical properties. In structural offshore and marine applications, as well as in the ... -
Dissolving Cylinder Zero-Order Kinetic Model for Predicting Hygrothermal Aging of Glass Fiber Bundles and Fiber-Reinforced Composites
(Chapter, 2018)Glass fibers and fiber-reinforced composites degrade when exposed to water. Understanding the dissolution behaviour of glass in fiber-reinforced composites is necessary to predict the changes in physical and mechanical ... -
Distributed Control of Flexible Manufacturing Systems: Implementation of a Specialized Multi-Agent Middleware and Applications of Holonic Concepts
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:290, Doctoral thesis, 2011)This PhD thesis reports on the application of the principles of distribution and autonomy from the multi-agent and holonic paradigms to smaller flexible assembly systems. In this specific context, available software ... -
Distributed Sacrificial Anode (DSA) - Properties in Mud and at Elevated Temperatures in Seawater
(Master thesis, 2017)Cost savings with regards to optimizing the Cathodic Protection (CP) design has over the last 50 years not been considered as a major opportunity so far. Sacrificial anodes combined with organic coatings is the main corrosion ... -
Distributed Sacrificial Cathodic Protection - A New Cost Effective Solution to Prevent Corrosion on Subsea Structures
(Master thesis, 2016)Over the last 50 years, only minor changes have been made to the cathodic protection (CP) design, whereas optimization has not been considered as a cost saving opportunity to date. For subsea structures, sacrificial anodes ... -

Do nothing, do minimum or do something? Why public project appraisals “always” recommend large projects
(Journal article; Peer reviewed, 2024)Purpose: In the project initiation phase, an appraisal is needed to clarify the strategic problem and alternative solutions. Full-scale construction projects and simple solutions (do-minimum alternatives) should be assessed. ... -
