Dynamic simulation of deep water drilling risers with heave compensating system
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:175, Doctoral thesis, 2012)This thesis discusses modelling aspects related to dynamic analysis of deep water drilling risers. These risers must have a heave compensator that maintains a near constant tension independent of platform motions. Traditional ... -
Dynamic simulation of future integrated energy systems
(Doctoral theses at NTNU;2019:213, Doctoral thesis, 2019)The building sector is responsible for a large part of the world's total energy use. More than half of building energy use is needed for space heating, domestic hot water heating, and space cooling. Thermal energy supply ... -
Dynamic Simulation of Gas Expansion in Marine Risers
(Master thesis, 2016)The main objective of the work is to study the dynamic behavior of gas expansion in marine risers. In case of well control situations in deep and ultra deep waters, gas influx shows no warnings if not little, making it ... -
Dynamic Simulation of Heat Exchanger with Multicomponent Phase Change
(Master thesis, 2017)A dynamic model for a heat exchanger with multicomponent phase change, part of reliquefaction cycle of natural gas, is developed. The finite control volume method is used to spatially discretize the heat exchange intro a ... -
Dynamic Simulation of Module Installation on Deep Water
(Master thesis, 2015)The Aasta Hansteen field is a gas field outside the coast of Northern Norway. Production is planned to start in 2017. The gas field is situated at 1300m water depth the deepest on the Norwegian continental shelf. During ... -
Dynamic Simulation of Power Systems Based on a Second Order Predictor-Corrector Scheme
(Master thesis, 2019)I denne masteroppgaven har den andreordens prediksjons-korreksjonsmetoden Gears metode blitt implementert i programmeringsspråket Python. Dette er en utvidelse av implementasjonen i spesialiseringsprosjektet. Gears metode ... -
Dynamic simulation of simultaneous HVDC contingencies relevant for vulnerability assessment of the nordic power system
(Chapter, 2019)Large power-infeed of individual HVDC interconnectors may make the power system vulnerable to contingencies involving multiple HVDC interconnectors. This paper describes and demonstrates an approach to quantitative ... -
Dynamic Simulations of Simultaneous HVDC Contingencies in the Nordic Power System Considering System Integrity Protection Schemes
(Master thesis, 2018)Individual HVDC links connecting the Nordic power system to other synchronous systems may carry gigawatts of power. For the transmission system operators, who must maintain power balance to operate the grid at 50.0 Hz, the ... -
Dynamic Spectrum Management in DSL Systems
(Master thesis, 2007)The candidate shall study different methods for dynamic spectral management in DSL systems, with main emphasis on autonomeous methods like iterative waterfilling. The methods shall be implemented in Matlab. -
Dynamic spending and portfolio decisions with a soft social norm
(Peer reviewed; Journal article, 2023)We explore the implications of a preference ordering for an investor-consumer with a strong preference for keeping consumption above an exogenous social norm, but who is willing to tolerate occasional dips below it. We do ... -
Dynamic Ssimulation Of Dart Anchor Installation
(Master thesis, 2015)Over the few last decades, numerous mooring concepts have been developed, one of these being the dart/ torpedo anchor. A torpedo anchor is shaped like an arrow and is equipped with tail fins to provide good directional and ... -
Dynamic State Estimation for Electrical Power Grids
(Doctoral theses at NTNU;2021:273, Doctoral thesis, 2021)Increased electrification of society, as well as increased incidence of distributed power generation, causes more dynamic operation of modern electrical power grids. Methods for monitoring of power grids have traditionally ... -
Dynamic stochasticmodeling for adaptive sampling of environmental variables using an AUV
(Peer reviewed; Journal article, 2023)Discharge of mine tailings significantly impacts the ecological status of the sea. Methods to efficiently monitor the extent of dispersion is essential to protect sensitive areas. By combining underwater robotic sampling ... -
Dynamic Storage Location Assignment Using Operator Idle Time for Reshuffling of Goods in a Manually Operated Warehouse
(Master thesis, 2022)Ettersom markedet for tredjepartslogistikk (3PL) har vokst de siste tiårene har konkurransen i bransjen også økt. Derfor må 3PL-leverandører være smartere i driften for å redusere kostnadene og forbli konkurransedyktige. ... -

Dynamic strain ageing in an AlMg alloy at different strain rates and temperatures: Experiments and constitutive modelling
(Peer reviewed; Journal article, 2022)Uniaxial tension tests at strain rates from to and temperatures from 298 to 418 K are performed to study the dynamic strain ageing (DSA) of an AA5182-O sheet. Digital image correlation (DIC) is used to obtain the stress-strain ... -
Dynamic strategy implementation
(Master thesis, 2015)Organizations consider strategies as vital in order to achieve their mission. For most organizations, strategies need to be adjusted as the world around them changes, but it often happens with some slowness, hesitation or ... -
Dynamic strategy of implementation
(Master thesis, 2015)The purpose of this thesis is to look at how a company can use a dynamic strategy process in order to adapt more quickly to changes in the surroundings, be it customers, owners or competitors. However, having adapted or ... -
