Dynamic two phase flow models for flushing
(Master thesis, 2014)This thesis aims at modeling the separated liquid-liquid flows with application for flushing. In the beginning, there will be a short review of the governing equations and the fundamental concepts used in this thesis. Two ... -
Dynamic use of the building structure - energy performance and thermal environment
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:51, Doctoral thesis, 2008)The main objectives of this thesis have been to evaluate how, under which premises, and to what extent building thermal mass can contribute to reduce the net energy demand in office buildings. The thesis also assesses the ... -
Dynamic versus quasi-static loading of X65 offshore steel pipes
(Journal article; Peer reviewed, 2016)Anchors or trawl gear occasionally impact offshore pipelines, resulting in large local and global deformations. Impact velocities are typically less than 5 m/s, but local strain rates may be very high. In this study strain ... -
Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface
(Peer reviewed; Journal article, 2020)Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ... -
Dynamic Wettability Alteration in Immiscible Two-phase Flow in Porous Media: Effect on Transport Properties and Critical Slowing Down
(Journal article; Peer reviewed, 2015)The change in contact angles due to the injection of low salinity water or any other wettability altering agent in an oil-rich porous medium is modeled by a network of disordered pores transporting two immiscible fluids. ... -
Dynamic wind farm layout optimization
(Master thesis, 2022)Recently, there has been an increase in interest in floating wind turbines that are located offshore. These turbines allow for the harvesting of the power of the wind far offshore, where wind speeds are often higher. Compared ... -
Dynamic Wireless Charging of Autonomous Vehicles: Small-scale demonstration of inductive power transfer as an enabling technology for self-sufficient energy supply
(Peer reviewed; Journal article, 2020)Recent developments toward selfdriving cars combined with technology for wireless inductive power transfer can enable electric vehicles that are fully autonomous with respect to operation and energy requirements. Furthermore, ... -
Dynamical electromechanical analysis of pole-piece rotors in pseudo direct-drive machines
(Master thesis, 2019)Wind energy has shown to be a great renewable energy source, with a possible penetration of 20% by 2040. In order to increase its competitiveness with fossil fuels, the LCOE should decrease further than it already has. ... -
Dynamical Model of Maritime Electric Power System
(Master thesis, 2007)A dynamical model of a maritime electric power system has been developed on assignment from ABB Marine. The model is implemented in Matlab Simulink. The model development and implementation have been done with regards to ... -
Dynamical Pose Estimation with Graduated Non-Convexity for Outlier Robustness
(Peer reviewed; Journal article, 2022)In this paper we develop a method for relative pose estimation for two sets of corresponding geometric primitives in 3D with a significant outlier fraction. This is done by using dynamical pose estimation as a solver in ... -
Dynamical Simulation of Causal Sets
(Master thesis, 2016)Two different dynamical schemes for production of physically meaningful causal sets are described and explored through the use of original computer simulations made using C++. Both of the schemes are found inappropriate ... -
Dynamical systems of interacting units: Information transport and higher order structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:1, Doctoral thesis, 2006)How can one model, characterize and analyse systems consisting of a large number of interacting units? This thesis addresses various related aspects of this issue using dynamical systems theory. The thesis is constituted ... -
Dynamical tuning between nearly perfect reflection, absorption, and transmission of light via graphene/dielectric structures
(Journal article; Peer reviewed, 2016)Exerting well-defined control over the reflection (R), absorption (A), and transmission (T) of electromagnetic waves is a key objective in quantum optics. To this end, one often utilizes hybrid structures comprised of ... -
Dynamical versions of Hardy's uncertainty principle: a survey.
(Peer reviewed; Journal article, 2021)Abstract: The Hardy uncertainty principle says that no function is better localized together with its Fourier transform than the Gaussian. The textbook proof of the result, as well as one of the original proofs by Hardy, ... -
Dynamical-Chemical Coupling in the Polar Middle Atmosphere: Effects of Energetic Particle Precipitation on the Middle Mesospheric Maximum
(Master thesis, 2019)Det midtre mesosfæriske ozonmaksimum er et nylig oppdaget fenomen, som finner sted i atmosfæren over polområdene vinterstid. Geomagnetisk aktivitet er kjent for å spille en viktig rolle i den midtre atmosfærens ozonbudsjett, ... -
Dynamically capturing engineering team interactions with wearable technology
(Chapter, 2015)This paper addresses the need of matching the product architecture and the interactions in design teams. A new method for this of how to build agile design teams was first introduced in 2013. We conducted a method-confirming ... -
