• Hydrodynamic modelling of a multi-body wave energy converter using the Moving Frame Method 

      Lande-Sudall, David; Nyland, Joakim; Rykkje, Thorstein Ravneberg; Stansby, Peter; Impelluso, Thomas (Peer reviewed; Journal article, 2023)
      Significant wave energy conversion may be achieved with multiple floats with several modes of motion combining constructively to generate power. With the M4 system, power take off is at hinges to absorb resulting pitch ...
    • A Kinematic Variable for Analyzing Snake Robot Dynamics 

      Rykkje, Thorstein Ravneberg; Impelluso, Thomas (Peer reviewed; Journal article, 2024)
      This paper presents a modern mathematical method to analyze snake robot dynamics. The method is rooted in three facets of contemporary mathematics: Cartan’s concept of endowing all moving bodies with their own reference ...
