21. 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 teknikSammanfattning : 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
22. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : 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. LÄS MER
23. 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)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
24. Simulation of flooding and flood mitigation in the town of Söderköping using HEC-RAS : An investigation of floods and mitigation measures
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : 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. LÄS MER
25. The Role of Technology Shifts in Urban Decarbonization Modelling : Scenario creation and implementation
Master-uppsats, KTH/EnergisystemSammanfattning : 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.
