  1. 1. Electrically Assisted Turbocharger: Modelling And Control Strategy

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Erik Vandor; Gabriel Ehlin; [2022]
    Nyckelord :EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Sammanfattning : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. LÄS MER

  2. 2. Bio-LNG and CO2 liquefaction investment for a biomethane plant with an output of 350 Nm3/h : A techno-economic-environmental analysis

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Lars-Julian Vernersson; [2022]

  4. 4. Effektivisering av bygglogistik : Utmaningar

    M1-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Haitham Al-Ameri; [2022]
    Nyckelord :Bygg; logistik; transport; miljö; politik; ekonomi; miljöpolitik; bränslepriser; byggbranschen; anläggning.;

    Sammanfattning : Varierande styrmedel samt olika politiska mål har gett upphov till varierande i bygginvesteringar. Detta har i sig lett till olika utmaningar inom byggbranschen främst inom bygglogistik. Bygglogistik och dess delar ihop med byggmaterial representerar 61% av byggkostnaden. Under de senaste 10 åren har byggkostnaden bara ökat. LÄS MER

  5. 5. Opposing ‘green’ extractivism: Voices of resistance in the case of the Gállok iron mine, Sápmi

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Sammanfattning : Embedded in a history of global colonial capitalism and the system’s crisis ridden tendencies and fixes for capital accumulation, extractivism increases globally. The intensive exploitation of resources is increasingly framed as compatible with and necessary to climate change mitigation for the possibility of a low-carbon future, opening new extractive frontiers through a path of ‘green’ extractivism (GE).
