  1. 1. Analys och optimering av transmissionslina till ett vinschbaserat vågkraftverk

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Författare :O’bryan Gaete; William Bruksås Nybjörk; [2020]
    Nyckelord :Fatigue; HMPE; Transmission line; Wave power plant; HMPE; Transmissionslina; Utmattning; Vågkraftverk;

    Sammanfattning : Detta examensarbete syftar sig till att undersöka olika konceptuella lösningar utav en transmissionslina för ett vågkraftverk. De tre olika konceptuella lösningarna är; ett rep av materialet HMPE (High Modulus Polyethylene), en transmissionslina baserad på KONE Ultrarope samt en transmissionskedja baserad på elastomera lager.

  2. 2. Defining requirements of PET scrap for open loop recycling of post-industrial waste

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Josephine Digné; [2020]
    Nyckelord :Chemical Engineering; plastics; thermoplastics; PET; polyethylene terephthalate; foamed plastics; recycling; post-industrial waste; circular economy; återvinning; kemiteknik; Technology and Engineering;

    Sammanfattning : To reduce the environmental impact and minimize the exploitation of the depleting re-sources, the transition to a circular economy is vital. It proposes an economy of reduced ma-terial consumption and increased reuse and recycling of plastics and other materials. LÄS MER

  3. 3. Conceptual design and construction of a UAV wing structure

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Selma Rahman; Anujan Ranganathan; [2020]
    Nyckelord :;

    Sammanfattning : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. LÄS MER

  4. 4. Polymer rejuvenation of PET textile waste

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sabrina Kopf; [2020]
    Nyckelord :PET; recycling; textiles; molecular weight;

    Sammanfattning : Thermomechanical recycling of polyethylene terephthalate (PET) typically includes a decrease in the polymer´s intrinsic viscosity and therefore a reduction of the molecular weight. Consequently, thermomechanical recycling is usually a downcycling of the product. LÄS MER

  5. 5. Mapping and investigation of carbon emissions from incineration of plastics : A thesis investigation on common polymers and how they should be managed

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Amelie Gustafsson; [2020]
    Nyckelord :;

    Sammanfattning : In November 2016 did the city of Stockholm adapt a strategy on by 2040 only utilizing fossil free fuel in alignment with the national target of reaching net zero carbon emissions by 2045. District heating is a well-established technology in Sweden heating about 50 % of the Swedish households and was in 2015 responsible for 58 % of the total energy demand in buildings and households.
