Modeling of nonlinear effects due to head-on beam-beam interactions
(Journal article; Peer reviewed, 2018)The beam-beam interaction is one of the most severe limitations on the performance of circular colliders, as it is an unavoidable strong nonlinear effect. As one aspires for greater luminosity in future colliders, one will ... -
Modeling of the Intermediate Band Tandem Solar Cell: Using the AM1.5 Spectra
(Master thesis, 2011)In this thesis the results from simulations of a tandem intermediate band solar cell are presented and discussed. Renewable energy sources have become increasingly important, because of global environmental concerns. To ... -
Modeling over-ageing in Al-Mg-Si alloys by a multi-phase CALPHAD-coupled Kampmann-Wagner Numerical model
(Journal article, 2017)The formation of the equilibrium precipitation phase during ageing treatment of Al-Mg-Si alloys is preceded by a series of metastable phases. Given longer ageing time, higher ageing temperature or elevated temperature ... -
Modeling surface nanobubbles in water electrolysis
(Master thesis, 2015)In this project a steady state approach is used to study the stability of surface nanobubbles in water electrolysis. A two dimensional domain is considered, where an electrode of length 100 nm is partly covered by a bubble. ... -
Modeling Susceptibility-induced Magnetic Field Distortion in the Human Head at 7 Tesla Using a Fourier-based Method
(Master thesis, 2022)Magnetisk susceptibilitet er en egenskap som alle materialer innehar og beskriver materiales tendens til å bli magnetisert når det befinner seg i et magnetisk felt. Den varierende fordelingen av magnetisk susceptibilitet ... -
Modeling the diffusion-weighted imaging signal for breast lesions in the b = 200 to 3000 s/mm 2 range: quality of fit and classification accuracy for different representations
(Peer reviewed; Journal article, 2020)Purpose To evaluate different non‐Gaussian representations for the diffusion‐weighted imaging (DWI) signal in the b‐value range 200 to 3000 s/mm2 in benign and malignant breast lesions. Methods Forty‐three patients ... -
Modeling the propagation of streamers in liquids - The Townsend-Meek criterion and a novel model for photoionization
(Master thesis, 2015)Conducting channels forms when a dielectric liquid is subjected to high electric stress. These channels are know as streamers, and if allowed the time to form and propagate, they can lead to an electrical breakdown. Sintef ... -
Modelled effects of temperature gradients and waves on the hydroxyl rotational distribution in ground-based airglow measurements
(Journal article; Peer reviewed, 2020)Spectroscopy of the hydroxyl (OH) airglow has been a commonly used way to remotely sense temperatures in the mesopause region for many decades. This technique relies on the OH rotational state populations to be thermalized ... -
Modellering av Termisk Stråling for Bruk i Brannsimuleringer.: En teoretisk analyse og studie av noen aspekter
(Master thesis, 2012)Numerisk løsning av termisk varmetransport spiller en viktig rolle i simuleringer av brann og andre systemer med høy temperatur, som er et sentralt anvendelsesområde for multifysikk-programpakken Brilliant som blir utviklet ... -
Modellering i termisk fysikk
(Master thesis, 2022)Den avsluttende masteroppgaven ved studiet MLREAL har jeg skrevet en oppgave i fysikkdidaktikk der jeg har forsket på modellering innen termisk fysikk i Fysikk 1. At programmering skal brukes i fysikk er forankret i ... -

Modelling and study of seismic airgun generated wave-field related to zooplankton survival
(Master thesis, 2021)Det er gjort flere studier om virkningen av menneskeskapt støy på marint liv, men de fleste omhandler virveldyr og større marine dyr. Innvirkningen på mindre livsformer som zooplankton har ikke blitt forsket på i like stor ... -
Modelling biodegradation of crude oil components at low temperatures
(Journal article; Peer reviewed, 2020)For oil spilled at sea, the main weathering processes are evaporation, emulsification, photo-oxidation, dispersion and biodegradation. Of these, only biodegradation may completely remove hydrocarbons from the environment ... -
Modelling Control Loops for SPS-LHC Beam Transfer Studies
(Master thesis, 2022)For HL-LHC æraen kan overføring av partikkelstråler fra SPS føre til tap av partikler og begrensninger i elektrisk effekt i radiofrekvens systemene til LHC. Presise numeriske modeller av kontrollsystemene i både SPS og LHC ... -
Modelling of a Solar Stove: Small Scale Concentrating System With Heat Storage: Potential For Cooking In Rural Areas, Zimbabwe
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:36, Doctoral thesis, 2008)The central objective of the present research is to serve as an in-depth technical introduction to small-scale concentrating systems tailored for application especially in rural areas in Africa located outside the national ... -
Modelling of Aerodynamic Drag in Alpine Skiing
(Master thesis, 2017)Most of the breaking force in the speed disciplines in alpine skiing is caused by the aerodynamic drag, and a better knowledge of the drag force is therefore desirable to gain time in races. In this study a complete database ... -
