    • Dynamic wind farm layout optimization 

      Kilinc, Ufuktan (Master thesis, 2022)
      Recently, there has been an increase in interest in floating wind turbines that are located offshore. These turbines allow for the harvesting of the power of the wind far offshore, where wind speeds are often higher. Compared ...
    • Dynamical Pose Estimation with Graduated Non-Convexity for Outlier Robustness 

      Smith, Torbjørn; Egeland, Olav (Peer reviewed; Journal article, 2022)
      In this paper we develop a method for relative pose estimation for two sets of corresponding geometric primitives in 3D with a significant outlier fraction. This is done by using dynamical pose estimation as a solver in ...
