  1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ayesha Nagahage; [2024]
    Nyckelord :Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Sammanfattning : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  2. 2. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER

  3. 3. Pricing of FX products - list rates

    Master-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorik

    Författare :Emma Edvardsson; [2023]
    Nyckelord :;

    Sammanfattning : List rates is a product that provides clients with a fixed exchange rate for a fixed period of time, varying from a few minutes up to a few days. During this period, the customer can exercise trading at the fixed exchange rate multiple times. The aim of this study is to find a pricing model for List rates. LÄS MER

  4. 4. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Eglantin Gjoni; [2023]
    Nyckelord :;

    Sammanfattning : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. LÄS MER

  5. 5. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Noah Norberg; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints. LÄS MER
