  1. 1. Optimal Gait Control of Soft Quadruped Robot by Model-based Reinforcement Learning

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

    Author : Niu Xuezhi; [2023]
    Keywords : Quadruped Robots; Soft Robotics; Reinforcement Learning; Gait Control; Model-Based Control Optimization; Kvadrupedroboter; Mjukrobotik; Förstärkningsinlärning; Gångkontroll; Optimering av robotkontroll;

    Abstract : Quadruped robots offer distinct advantages in navigating challenging terrains due to their flexible and shock-absorbing characteristics. This flexibility allows them to adapt to uneven surfaces, enhancing their maneuverability. READ MORE

  3. 2. Analysis of Observed Discrepancies in Precipitation Measurements in the Complex Terrain of East-Iceland

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Páll Ágúst Þórarinsson; [2021]
    Keywords : Precipitation; precipitation measurements; weather observation; complex terrain; weather regimes; Iceland; Nederbörd; nederbördmätningar; väder observationer; komplex terräng; vädersituationen; Island;

    Abstract : Spatial distribution of precipitation in complex terrain can be very uneven and there are many factors to consider when studying it. The goal of this study was such a problem; to analyse the difference in observed annual precipitation in the complex terrain of Seyðisfjörður, a fjord in East-Iceland. The study was carried out in three parts. READ MORE

  4. 3. Impact of different atmospheric forcings on surface mass balance estimates in Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stina Olandersson; [2018]
    Keywords : Physical Geography and Ecosystem analysis; surface mass balance; Greenland; climate models; numerical weather prediction models; surface energy balance; Arctic; climate change; Earth and Environmental Sciences;

    Abstract : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. READ MORE

  5. 4. Potentials and limitations of 1D, 2D and coupled 1D-2D flood modelling in HEC-RAS

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Alexander Betsholtz; Beatrice Nordlöf; [2017]
    Keywords : Hydraulic modelling; HEC-RAS; 1D; 2D; 1D-2D; flooding; sub-grid; Technology and Engineering;

    Abstract : Hydraulic models can be used to predict the consequences of flooding events. In this project, three hydraulic models were constructed using the software HEC-RAS, and compared through a case study on Höje river catchment. READ MORE

  6. 5. Modelling of ice throws from wind turbines

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Joakim Renström; [2015]
    Keywords : Ice throw; icing; wind turbines; balistic model; Iskast; nedisning; vindkraftverk; ballistisk modell;

    Abstract : As the wind energy sector expands into areas with colder climate, the problem with ice throw will increase. Due to a rotor diameter of more than 120 meters for a typical modern turbine with an effect of 3.3 MW, the separated ice fragment will get a high initial velocity, and therefore, they will also be thrown a long distance.
