Modelling, Simulation and Optimization of Crash Components in Aluminium

Solhjem, Espen; Kjus, Eivind Sogn (Master thesis, 2017)

The main focus of this thesis was to establish a validated finite element model of an extruded rectangular hollow profile with a single chamber. Experimental axial crushing tests were carried out on various heat treated ...

Modelling, Simulation, and On-line Detection of Rotor Eccentricity in Hydropower Generators

Møller, Andreas Blix (Master thesis, 2018)

The generator is a critical component in the hydropower power plant, and detection of its fault conditions is important for safe and cost-effective operation. A new proposed method for detection of rotor interturn short ...

Modelling, Simulation, and On-line Detection of Rotor Fault in Hydrogenerators

Jørstad, Kari Gjerde (Master thesis, 2017)

Hydropower generator is a critical component in hydropower stations and is therefore subject to a preventive maintenance strategy to avoid failures of the generator's components. Fault detection techniques can be used to ...

Modellprediktiv regulering av oksygenkonsentrasjon hos KOLS-pasienter

Malde, Eline (Master thesis, 2019)

Noen KOLS-pasienter får ekstra oksygenrik pustegass for å avhjelpe respirasjonen, hvor mengden oksygen i dag styres manuelt. For mye oksygen kan gi pasienten et redusert behov for å trekke pusten og dermed føre til opphopning ...

Modelltester av Peltonturbiner ved Vannkraftlaboratoriet

Trefall, Stine (Master thesis, 2011)

Ved design av nye turbiner kan modelltester gjennomføres for å kartlegge driftsområde og ytelse. Informasjon fra testene kan benyttes til å avdekke eventuelle feil og estimere levetid. Modelltester kan videre benyttes til ...

Modelltesting av snøplog

Oda Berg Aspevold (Master thesis, 2019)

Sammendrag Motivasjonen for denne oppgaven var at når en plogprodusent ønsket å utvikle en ny plog hadde de ikke annet alternativ enn å lage den nye plogen i fullskala og teste den mot en annen plog i et feltforsøk. Dette ...

Models and Methods for Efficiency Estimation of a Marine Electric Power Grid

Bø, Torstein Ingebrigtsen; Pedersen, Eilif (Chapter; Peer reviewed, 2017)

Diesel electric propulsion has become industry standard for many marine applications. Typically, a significant part of the operations of vessels with diesel electric propulsion is done with low loads on the motors and ...

Models and Methods for Investigation of Reverberations in Nonlinear Ultrasound Imaging

Høilund-Kaupang, Halvard (Doktoravhandlinger ved NTNU, 1503-8181; 2011:217, Doctoral thesis, 2011)

Models and methods for investigation of reverberations in nonlinear imaging techniques are presented in this thesis. Four independent papers provide insight on nonlinear propagation effects, a theoretical description of ...

Models and numerical methods for two-phase flow of CO2 in pipes

Reinertsen, Aleksander (Master thesis, 2015)

Key to the transport phase of carbon capture and storage (CCS) is understanding the behavior of liquid or supercritical CO2 in pipelines, and the consequences of cracks and pipe depressurization. It is therefore useful to ...

Models for dense multilane vehicular traffic

Risebro, Nils Henrik; Holden, Helge (Journal article; Peer reviewed, 2019)

We study vehicular traffic on a road with multiple lanes and dense, unidirectional traffic following the traditional Lighthill--Whitham--Richards model where the velocity in each lane depends only on the density in the ...

Models for Internationalisation of After-Sales and Support Function of Engineering Derived Company in the Oil Service Market

Sørhage, Arne (Master thesis, 2011)

During the last couple of decades the "oil service" industry, which evolved around the North Atlantic oil & gas exploration and production market, has to an increasing extent cast its eyes on new and often emerging markets. ...

Models for lifetime estimation: an overview with focus on applications to wind turbines

Welte, Thomas Michael; Wang, Kesheng (Journal article; Peer reviewed, 2014)

This paper provides an overview of models and methods for estimation of lifetime of technical components. Although the focus in this paper is on wind turbine applications, the major content of the paper is of general nature. ...

Models for Punching Shear Capacity in Concrete Slabs

Bølviken, Ingeborg Skarholt (Master thesis, 2013)

Model Code 2010 was published in the spring of 2012 by the International Federation for Structural Concrete (fib), and presents a whole new model for punching shear design. Whereas the method for punching shear design in ...

Models of the Optimal Resource Allocation for the Critical Infrastructure Protection

Norkin, Vladimir I.; Gaivoronski, Alexei A.; Zaslavsky, VA; Knopov, Pavel S. (Journal article; Peer reviewed, 2018)

Adaptation of the operations research models and methods to planning of the critical infrastructure protection is considered. Adaptation of these models includes taking into account stochastic, informational, and behavioral ...
