  1. 21. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Frida Agerberg; [2020]
    Keywords : Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Abstract : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. READ MORE

  3. 22. RFID for more effective and efficient train maintenance : A case study of a train depot in a deregulated market

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

    Author : Diana Henningsson; Olivia Wendel; [2019]
    Keywords : RFID; effective and efficient train maintenance; deregulated train markets; optimal utilization of train depots.; RFID; effektivt tågunderhåll; avreglerade tågmarknader; optimalt utnyttjande av tågdepåer.;

    Abstract : In this master thesis the potential value of using RFID technology in train depots has been investigated. Train depots are a crucial part of the railway system as safe and timely traffic relies on the maintenance activities preformed in them. READ MORE

  4. 23. Photogrammetry for health monitoring of bridges : Using point clouds for deflection measurements and as-built BIM modelling

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Joel Delehag Lundmark; [2019]
    Keywords : ;

    Abstract : Road and railway bridges play a crucial role for the infrastructure network in Sweden to work smoothly and keep the traffic flowing. Damage to a bridge can have catastrophic consequences if they are not corrected properly and in due time. READ MORE

  5. 24. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

    University essay from KTH/Transportplanering

    Author : Filipp Zarov; [2019]
    Keywords : maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

    Abstract : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.

  6. 25. Extracting masts of overhead supply and street lights from point cloud

    University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Yi Zhu; [2019]
    Keywords : Support Vector Machine; point cloud; laser scanning; automatic extraction;

    Abstract : Regular inspection and documentation for railway assets are necessary to monitor the status of the traffic environment. Mobile Laser Scanning (MLS) makes it possible to collect highly accurate spatial information of railway environments in the form of point cloud, and an automatic method to extract interested objects from the point cloud is needed to avoid too much manual work.
