  1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Erik Nordlund; [2023]
    Nyckelord :Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Sammanfattning : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. LÄS MER

  3. 2. CFD-modeling of labyrinth weir flood discharge with ice cover

    Master-uppsats, KTH/Betongbyggnad

    Författare :Erik Isberg; [2023]
    Nyckelord :;

    Sammanfattning : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. LÄS MER

  4. 3. Kvantifiering av stenmängd i massavedsleveranser

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)

    Författare :Erik Näsmark; [2023]
    Nyckelord :sten; massaved; underlag; snödjup; massavedsleveranser;

    Sammanfattning : Stora volymer massaved levereras dagligen till olika industrier i landet. Virket som levereras från skogen hanteras flertalet gånger av gripar och det finns därmed en stor risk att föroreningar som stenar kan följa med till industrierna. LÄS MER

  5. 4. Usability of connected vehicle data for local winter road maintenance

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Erik Lindgren; [2023]
    Nyckelord :Winter Road Maintenance; Road Weather; Decision Support Systems;

    Sammanfattning : NIRA is a company based in Linköping and operates within the automotive industry. NIRA's Tire Grip Indicator is one of their products used to create friction values during normal driving conditions. This data is, together with additional sensor information from the vehicle, such as environmental sensors, collected in NIRA's cloud environment RSI. LÄS MER

  7. 5. Spatial co-occurrence between wind power and boreal forestlands with lichen important for reindeer browsing : a landscape analysis

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Erik Lundmark; [2022]
    Nyckelord :lichen; qGIS; reindeer; reindeer husbandry; spatial analysis; wind power;

    Sammanfattning : To meet the increasing demand of renewable energy, Sweden aim to expand the onshore wind power production from 30 TWh today, to 80 TWh by 2040. Most wind power sites will be placed in Northern Sweden, which coincides with the reindeer husbandry area, where indigenous Sami have a legislated reindeer husbandry right. LÄS MER
