A comparison of Eulerian and Lagrangian methods for vertical particle transport in the water column
Nordam, Tor; Kristiansen, Ruben; Nepstad, Raymond; van Sebille, Erik; Booth, Andy (Journal article, 2023)A common task in oceanography is to model the vertical movement of particles such as microplastics, nanoparticles, mineral particles, gas bubbles, oil droplets, fish eggs, plankton, or algae. In some cases, the distribution ... -
Motion Planning for Robotic Manipulators
Kristiansen, Ruben (Master thesis, 2014)In this thesis motion planning for robotic manipulators is considered. A mathematical model describing the kinematics and dynamics of a manipulator based on a bounding box model of ABB's IRB140 is developed. Variants of ... -
Numerical analysis of boundary conditions in a Lagrangian particle model for vertical mixing, transport and surfacing of buoyant particles in the water column
Nordam, Tor; Kristiansen, Ruben; Nepstad, Raymond; Röhrs, Johannes (Journal article; Peer reviewed, 2019)Lagrangian particle models are used for many applications in the ocean sciences, including transport modelling of oil spills, fish eggs and larvae, plastics, and sediment particles. In the context of oil spill modelling, ...
