  1. 6. Investigation of coarse-grid CFD approach for nuclear engineering application

    Master-uppsats, KTH/Fysik

    Författare :Michela Casarella; [2023]
    Nyckelord :Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

    Sammanfattning : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

  3. 7. Utvärdering av ankomstprognoser för tåg

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Linus Rydstedt; [2023]
    Nyckelord :Train delay; traffic management; evaluation; arrival forecast; prediction; Technology and Engineering;

    Sammanfattning : In this master thesis, an evaluation of arrival forecasts for trains is made to see how various prediction sources compare to each other and how well these reflect reality. Furthermore, this thesis is a sprint of a research project that is carried out and conducted at Lund University of Technology on behalf of the Swedish Transport Administration. LÄS MER

  4. 8. Impact of Cell Type Selection on Binary Classification of Cervical Cancer using Convolutional Neural Networks : A Compatibility Analysis of Herlev and SIPaKMeD

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Elias Ram; Elias Stihl; [2023]
    Nyckelord :;

    Sammanfattning : Cervical cancer is one of the most common forms of cancer today, affecting women worldwide. Machine learning classifiers could potentially be utilized to aid in the diagnosis of cervical cancer, making screening more cost-effective. LÄS MER

  5. 9. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Jacobsson Trönndal; [2023]
    Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
