    Sammanfattning : Bilindustrin är en av de största bidragsgivarna till koldioxidutsläpp genom fordonsutsläppnär de används. För att göra transportsektorn mer hållbar EU-politik dikterar att inkludera enhögre andel förnybara energikällor i den totala energiförbrukningen och ett sätt att uppnå det äratt införliva biobränslen i de traditionella fossila bränslena.

  3. 32. Dynamic prediction of repair costs in heavy-duty trucks

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Lakshidaa Saigiridharan; [2020]
    Nyckelord :Hurdle Gamma model; Hierarchical hurdle Gamma model; Generalized linear model GLM ; Supervised Machine Learning; feature selection; Akaike Information Criterion AIC ; prediction of repair costs; heavy-duty trucks; truck variants; operational features;

    Sammanfattning : Pricing of repair and maintenance (R&M) contracts is one among the most important processes carried out at Scania. Predictions of repair costs at Scania are carried out using experience-based prediction methods which do not involve statistical methods for the computation of average repair costs for contracts terminated in the recent past.

    Nyckelord :Heavy Duty Trucks; Global warming potential; Automation technology; Environmental impacts; Electric trucks; Life cycle assessment;

    Sammanfattning : Trucks are used to transport goods and services using road transportation. Emissions from the transportation industry are rising with every passing year. The Swedish government said in a report in 2009 that they are working to reduce 70% of the greenhouse gas emissions by 2030 to build a pathway for sustainable transportation (Allerup, 2019). LÄS MER

  5. 34. Time dependent modeling of turbocharger failure using machine learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Felix Liljefors; [2020]
    Nyckelord :;

    Sammanfattning : Data-driven predictive vehicle maintenance can in principle reduce the risk of costly breakdowns, damaged cargo, and increased emissions due to faulty components. However, implementing a cost efficient predictive maintenance policy is far from trivial. LÄS MER

  7. 35. Alternative Drivetrain for Future Freight Trucks

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Athanasios Tsamos; [2020]
    Nyckelord :future freight trucks; transportation; sustainable fuels; alternative fuels; future mobility; long distance trucks; hybrid mobility; alternative drivetrain; electric trucks;

    Sammanfattning : Presently, heavy-duty trucks are responsible for approximately 25% of global CO2 emissions. Although the world seems to incline towards the transport sector's electrification, the electrification of long-range freight trucks is profoundly challenging. LÄS MER
