  1. 11. Turbulent Boundary Layers Modelling with Deep Operator Networks

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yu-Cheng Lu; [2023]
    Keywords : Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

    Abstract : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

  3. 12. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  4. 13. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Aayush Desai; [2023]
    Keywords : Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Abstract : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. READ MORE

  5. 14. Finding stars that are likely to be from accreted satellite galaxies

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Helena Cronstedt; [2023]
    Keywords : galaxy mergers; merger debris; velocity space; Physics and Astronomy;

    Abstract : The Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. READ MORE

  6. 15. Comparison of different approaches for modelling the beam-target reactivity in fusion plasmas

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Petersson; [2022]
    Keywords : JET; Fusion; Fusion Diagnostics; Computational Physics; Modelling; NBI; Beam-Target Reactivity;

    Abstract : Fusion research has been an ongoing research endeavour for many decades and it has the potential of providing an important part in the future of energy production. An important part of this process is to understand and control the various heating systems of the reactor where one of the most important systems being the Neutral Beam Injector (NBI) which injects particles at high velocities into the plasma.
