    • Implementation and Control of an Inverted Pendulum on a Cart 

      Hanekam, Halvard (Master thesis; Mastergradsoppgave, 2021-05-28)
      An Inverted Pendulum on a Cart is a common system often used as a benchmark problem for control systems. The system consists of a cart that can move in one direction on the horizontal plane and a pendulum attached to the cart through a hinge point. The pendulum can rotate 360° on the plane made up of the vertical direction and the direction the cart can move. The system is controlled by applying a ...
    • Simulation of Meteorological and Oceanographic Parameters: An Application in Spray Icing Prediction 

      Shojaei Barjouei, Abolfazl (Master thesis; Mastergradsoppgave, 2020-07-13)
      Sea spray icing is considered as a major environmental challenge in the Arctic Ocean, which poses a critical risk not only to the vessels and industrial operations but also to human safety. Although some studies have been carried out to estimate spray icing rate (e.g., RIGICE04 and ICEMOD models), such models suffer from some unrealistic modeling assumptions and limited verification. Moreover, limited ...
