  1. 1. Mapping Noise Pollution with Open-source GIS

    Master-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Faustina Lina Yeboah; [2021]
    Nyckelord :Road traffic noise; CNOSSOS-EU; noise exposure; Lday; Levening; Lnight; Lden;

    Sammanfattning : In a time when urban areas continue to expand, environmental noise pollution especially from road traffic remains a big challenge. This study was aimed at using open-source GIS tools to predict road traffic noise pollution using the mid-sized city of Gävle as a case study. LÄS MER

  3. 2. Modelling of stormwater treatment in biofilters using MIKE+ : Possibilities and limitations

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cecile Bouju; [2021]
    Nyckelord :Biofilter; Raingarden; Stormwater treatment; Stormwater management; Hydrological modelling; MIKE ; ECO Lab; Biofilter; Växtbädd; Dagvattenrening; Dagvattenhantering; Hydrologisk modellering; MIKE ; ECO Lab;

    Sammanfattning : As research has expanded on the environmental impact of stormwater on receiving ecosystems more focus is now being put on the quality issues of stormwater. Biofilters are one of many nature-based solutions that have been developed for that purpose and are also the subject of this study. LÄS MER

  4. 3. Using X-band Radar with a Neural Network to Forecast Combined Sewer Flow - A case study in Lund

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Filip Faust; Per Nelsson; [2020]
    Nyckelord :X-band radar; neural networks; combined sewer; forecasting; urban hydrology; Lund; Technology and Engineering;

    Sammanfattning : This study aimed to forecast combined sewer flow into a wastewater treatment plant in Lund, Sweden by using uncalibrated X-band radar data with a neural network. Neural networks have proved themselves useful in the field of forecasting as they can solve multiple kinds of problems and recognise patterns in the data (Alemu et al. LÄS MER

  5. 4. Effects of repeated whole-body cold stress on finger temperature responses to localized cooling

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Pit Gäng; [2020]
    Nyckelord :CIVD; whole-body cold acclimation; cutaneous blood flow; immersion; thermal perception;

    Sammanfattning : The study aimed to assess whether a short-term, high-intensity cold acclimation protocol would modulate finger vasomotor [i.e., finger temperature (TF), cold induced vasodilation (CIVD)] responses and regional thermo-perception to localized cooling. LÄS MER

  7. 5. Design of a Dynamic Boom Suspension System in a Hybrid Wheel Loader

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Ayoub Ayoub; Carl Martin Berg; [2018]
    Nyckelord :Wheel loaders; passive damming; active damping; dynamic damping; PID controllers; vibrations; hydraulics.;

    Sammanfattning : Wheel loaders are under the influence of low frequency vibrations that may be harmful for the health of the operator, and for the productivity of the machine. The strong vibrations can significantly impact the operation of the machine since they are not equipped with wheel suspension systems and due to their work environment in rough terrains with uneven surfaces.
