  1. 1. Modelling the Occurrence and Fate of Microplastics Caused by Tyre Wear on Highway E18

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Aniruddha Kshirsagar; [2023]
    Nyckelord :Tyre Wear Plastics; stormwater system; Microplastics; settling; hetero-aggregation; modelling; Modellering; mikroplaster;

    Sammanfattning : The accumulation of microplastics (MPs) are a growing concern for the environment, the maximum contributor to the MP pollution is tyre wear particles or TWPs. TWPs can accumulate in the environment and remain there for long periods of time and hence have the ability to disrupt ecosystems. LÄS MER

  3. 2. Redesign of a tribological pin-on-disc machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Michal Szumin; [2022]
    Nyckelord :tribometer; particulate matter; studded tyres; tyre-road contact; tribometer; partiklar; dubbdäck; kontakt mellan däck och väg;

    Sammanfattning : In contradistinction with road transport exhaust particulate matter (PM) emission, non-exhaust PM emission has not decreased substantially in recent years. One source of non-exhaust PM emission is studded tyre-pavement contact. LÄS MER

  4. 3. Tyre sound classification with machine learning

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Datavetenskap

    Författare :Aghyad Jabali; Husein Abdelkadir Mohammedbrhan; [2021]
    Nyckelord :Sound Classification; Machine learning; Support vector machine SVM ; Convolutional Neural Network CNN ; Random Forest.;

    Sammanfattning : Having enough data about the usage of tyre types on the road can lead to a better understanding of the consequences of studded tyres on the environment. This paper is focused on training and testing a machine learning model which can be further integrated into a larger system for automation of the data collection process. LÄS MER

  5. 4. Geofysiska mätmetoder för prospektering till ballastmaterial

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Erik Bohlin; Ludvig Landen; [2008]
    Nyckelord :prospektering; ballastmaterial; LosAngeles test; microDeval test; kulkvarnstest; resistivitet; IP; normaliserad IP; refraktionseismik; tomografi; geofysik; geologi; aggregate prospecting; electrical resistivity imaging; induced polarization; normalized induced polarization; refraction seismics; tomography; studded tyres test; geophysics; geology; Earth and Environmental Sciences;

    Sammanfattning : The Swedish rock-mass industry is currently in a transition period because new rules and regulations strongly limit the possibility to use naturally sorted aggregates for construction and concrete purposes. Furthermore, research and development within the industry is more oriented towards crushed bedrock aggregates. LÄS MER
