    Keywords : Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Abstract : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. READ MORE

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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mathieu Minaud; [2024]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 19. Simulation of flooding and flood mitigation in the town of Söderköping using HEC-RAS : An investigation of floods and mitigation measures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andreas Hoppe; [2024]
    Keywords : ;

    Abstract : This study examines the effects of flood management systems in an HEC-RAS simulation of recorded discharge in the town of Söderköping in Sweden by using easy-to-access and publicly available hydrological, landcover, and soil data. Two rivers and the precipitation of a chosen area are studied. READ MORE

  6. 20. The Role of Technology Shifts in Urban Decarbonization Modelling : Scenario creation and implementation

    University essay from KTH/Energisystem

    Author : Batiste Fourniols; [2024]
    Keywords : Urban area; Decarbonization policies; Scenario modeling; District heating; Gas distribution network; Geospatial resolution; Stadsområde; utfasning av fossila bränslen; scenariomodellering; fjärrvärme; gasdistributionsnät; geospatial upplösning;

    Abstract : This work includes modelling of decarbonization scenarios at the scale of an urban area, providing policy insights and a methodology focusing on introducing district heating and maintaining the existing gas distribution network in a case study. With a focus on reducing gas consumption in the residential and tertiary sectors, the research integrates scenario developments giving a methodology to develop district heating, requiring a careful balance in selecting the optimal scale for city-wide analysis.
