  1. 1. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Kosei Nishida; [2020]
    Keywords : SPH; Landslide-generated waves; non-newtonian fluid; multiphase flow; Technology and Engineering;

    Abstract : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. READ MORE

  2. 2. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annica Gustafsson; [2019]
    Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

    Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

    Abstract : Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. READ MORE

  4. 4. Reinforcement Learning– Intelligent Weighting of Monte Carlo and Temporal Differences

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Martin Christiansson; [2019]
    Keywords : Technology and Engineering;

    Abstract : In Reinforcement learning the updating of the value functions determines the information spreading across the state/state-action space which condenses the valuebased control policy. It is important to have an information propagation across the value domain in a manner that is effective. READ MORE

  5. 5. Cluster-based Sample Selection for Document Image Binarization

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Amandus Krantz; [2019]
    Keywords : document image binarization; sample selection; neural networks; computer vision;

    Abstract : The current state-of-the-art, in terms of performance, for solving document image binarization is training artificial neural networks on pre-labelled ground truth data. As such, it faces the same issues as other, more conventional, classification problems; requiring a large amount of training data. READ MORE
