  1. 1. Reconstructing point patterns from spatially aggregated data

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jens Michelsen; [2024-03-13]
    Nyckelord :lorem; ipsum; dolor; sit; amet; consectetur; adipisicing; elit; sed; do.;

    Sammanfattning : In this thesis we explore the ability to reconstruct samples (point configurations) from a point process, based only on the information contained in spatially aggregated data, namely the number of points in the partitions of a larger region. The ability to reconstruct a point configuration, in such a way that it retains most of it’s statistical properties, could be useful in cases where one is faced with a mixed dataset; some regions containing the full point configuration data, while other regions only contain aggregated data, i.

  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. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  4. 4. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Kreshnik Margaritari; [2023]
    Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  5. 5. Wildfire growth modelling in Sweden - a suitability assessment of available data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Henrik Hagelin; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

    Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER
