  1. 1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Merhawi Belai; [2024]
    Nyckelord :nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Sammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER

  3. 2. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

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

    Författare :Mathieu Minaud; [2024]
    Nyckelord :;

    Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER

  4. 3. Modellering av extern fosforbelastning till Vombsjön : En studie med hydrologiska modellen Soil and Water Assessment Tool, SWAT+

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Johanna Jönsson; [2024]
    Nyckelord :Phosphorus; Eutrophication; Agriculture; Hydrological Model; Soil and Water Assessment Tool; Fosfor; övergödning; jordbruk; hydrologisk modell; Soil and Water Assessment Tool;

    Sammanfattning : Vombsjön är en av de viktigaste dricksvattentäkterna i södra Skåne som förser bland annat Malmö och delar av Lund med dricksvatten. Sjön lider av övergödning och återkommande algblomningar som komplicerar dricksvattenproduktionen. LÄS MER

  5. 4. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Léa Chatelais; [2024]
    Nyckelord :MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Sammanfattning : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. LÄS MER

  7. 5. Activity Location Assignment Comparison Using Geospatial Landuse and Building Data in MATSim : A Multi-modal Transport Case Study of Stockholm

    Master-uppsats, KTH/Transportplanering

    Författare :YU GAO; [2023]
    Nyckelord :Agent-based model; MATSim; Raster Data; Shapefile Data; OSM; GTFS;

    Sammanfattning : Transport simulation models play a crucial role in transportation planning, design, and operations, allowing for the replication of various scenarios through the incorporation of real-world data and parameters. Recently, agent-based transport models have gained prominence for their ability to simulate intricate metropolitan transport systems. LÄS MER
