  1. 16. Paper Machine Press Felt Monitoring : A Case Study on PM2 in Karlsborg

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Aron Laurell Håkansson; [2021]
    Nyckelord :paper machine; press fabric; press felt; vibration; condition monitoring; pappersmaskin; pressduk; pressfilt; vibration; tillståndsövervakning;

    Sammanfattning : Press felts are highly critical components of the paper machine. A degraded press felt could lead to paper web breaks, which requires the paper machine to be restarted. Moreover, a degraded felt influences the quality of the paper, leading to paper disposal. LÄS MER

  3. 17. The Potential of Electrification in reducing Emissions from Passenger Cars in Stockholm County by 2030 : A Modeling Study of the Potential of Plug-In Hybrids and All-Electric Cars in reducing Greenhouse Gas Emissions and Air Pollution

    Master-uppsats, KTH/Transport och systemanalys

    Författare :Arvid Hedbäck; [2021]
    Nyckelord :electric cars; electrification; Stockholm; 2030; modeling; Scaper; HBEFA; CO2; air pollution; nitrogen oxides; NOx; hydrocarbons; HC; particulate matter; PM10; PM2.5;

    Sammanfattning : This study examines the potential of electrification in reducing greenhouse gas emissions and air pollution from passenger cars in a short- to mid-term time perspective. Using Stockholm County as a case study, this has been done in a three-step process by modeling the relative change in emissions between 2019 and 2030. LÄS MER

  4. 18. Addressing a large-scale implementation of low-emission zones in France

    Master-uppsats, KTH/Systemanalys och ekonomi

    Författare :Mina Roncière; [2020]
    Nyckelord :low-emisson zone; air quality; air pollution; transport policy; urban typology;

    Sammanfattning : Air pollution is a public health issue, and traffic is one of the main sources of pollutants such as NO2, PM10 and PM2.5. Consequently, European cities have been implementing low-emission zones (LEZs) by defining regulated areas, where the most-polluting vehicles are prohibited from driving. LÄS MER

  5. 19. WRF-Chem vs machine learning approach to predict air quality in urban complex terrains: a comparative study

    Master-uppsats, Högskolan Dalarna/Mikrodataanalys

    Författare :Andrey Kudryashov; [2020]
    Nyckelord :Machine learning; WRF-Chem; comparative study; air quality;

    Sammanfattning : Air pollution is the main environmental health issues that affects all the regions and causes millions premature deaths every year. In order to take any preventive measures, we need the ability to predict pollution level and air quality. This task is conventionally solved using deterministic models. LÄS MER

  7. 20. Studie av partikelutsöndringar från FDM-teknologi

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för kvalitets- och maskinteknik

    Författare :Johan Sundström; [2020]
    Nyckelord :Fused Deposition Modeling; Air pollution; Particulate matter; Fused Deposition Modeling; Luftföroreningar; Luftburna partiklar;

    Sammanfattning : 3D-skrivare baserade på FDM-teknik sprider sig snabbt på marknaden på grund av kommersiell tillgänglighet, låga ingångspris och allt mer  användarvänliga enheter. I takt med att additiv tillverkning kommer allt närmare hemmet är det viktigt att veta hur vår hälsa påverkas när vi sitter intill. LÄS MER
