A numerical framework for estimating the effective reproduction number of infectious diseases from compartmental epidemic models
(Peer reviewed; Journal article, 2021)We present a numerical framework for estimating the effective reproduction number of infectious diseases from compartmental epidemic models. The idea is to augment the reproduction number as an extended state variable in ... -
Numerical integration in inverse problems for ordinary differential equations
(Master thesis, 2022)Dersom ein kjenner punkter av løysinga til ei ordinær differensiallikning (ODE), handlar det inverse problemet om å finne ein approksimasjon av vektorfeltet. Ei forskingsretning som nyleg har vorte særs aktiv, dreier seg ... -
Numerical investigation of blade roughness impact on the aerodynamic performance and wake behavior of horizontal axis wind turbine
(Peer reviewed; Journal article, 2023)This research focuses on the effect of leading-edge erosion on the performance of wind turbines, specifically the GE1.5XLE horizontal axis wind turbine. The blade element momentum (BEM) method is used to predict the ... -
Numerical investigation of modeling frameworks and geometric approximations on NREL 5 MW wind turbine
(Journal article; Peer reviewed, 2018)The key to the better design of an industrial scale wind turbine is to understand the influence of blade geometry and its dynamics on the complicated flow-structures. An industrial-scale wind turbine can be numerically ... -
Numerical Methods and Brute Force Optimisation for a General Formulation of the Mean Field Game Equations
(Master thesis, 2015)This thesis considers the numerical solution of a general formulation of the mean field game (MFG) equations. MFG are a relatively new field with few general results but with many modelling applications. The MFG equations ... -
Numerical Methods for Electromagnetic Field Propagation over an Undulating Surface in the Frequency Region of 110 MHz
(Master thesis, 2013)When an aircraft is landing, the use of the Instrument Landing System (ILS) is essential. It provides navigation signals for the landing aircraft. The localizer transmits the signals for horizontal navigation, and is ... -
Numerical Methods for Highly Oscillatory Problems
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:115, Doctoral thesis, 2010)Classical quadrature methods, i.e. methods for numerical integration,require discretizations that become more fine the more the integrandis oscillating. Conversely, asymptotic methods provide approximationsof the same ... -
