  4. 8. Monitoring and Modelling of the Abiskojåkka Bridge

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Furenstam; [2020]
    Nyckelord :Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

    Sammanfattning : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. LÄS MER

  5. 9. A Machine Learning-Based Approach for Fault Detection of Railway Track and its Components

    Master-uppsats, Luleå tekniska universitet/Drift, underhåll och akustik

    Författare :Johnny Asber; [2020]
    Nyckelord :Condition Based Maintenance in Railway; Machine Learning; Deep Learning; ResNet-50;

    Sammanfattning : The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Joel Delehag Lundmark; [2019]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
