    Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER

  3. 2. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development

    Författare :Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Mario Hirz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle energy optimisation; Multidisciplinary optimisation; Integrative design; Sustainable vehicle design; Functional conflicts; Vehicle aerodynamics; Battery energy storage systems; Robust design; Uncertainty propagation; Livscykelenergi; Fordonsdesign; Optimering; Tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.

  4. 3. Expansive design for teachers : An activity theoretical approach to design and work integrated learning

    Författare :Dennis Augustsson; Åsa Mäkitalo; Thomas Winman; Anne Edwards; Högskolan Väst; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Participatory design; Activity theory; Expansive learning; Teaching; Professional development; Education; Work Integrated Learning; Arbetsintegrerat lärande; Utbildningsvetenskap; Educational science;

    Sammanfattning : This thesis explores how Participatory Design (PD) and Cultural Historical Activity Theory (CHAT) can be combined and used as a theoretical framework and methodology in a professional development activity for teachers. A shift in the way we view teachers, from implementors to designers who actively construct, invent, and develop the practice of schooling also calls for changes in teacher education and professional development activities.

  5. 4. Designing for Change in Complex Systems : Design Considerations for Uptime in a Transportation System with Driverless Vehicles

    Författare :Lina Rylander; Jonas Mårtensson; Magnus Eneberg; Josina Vink; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Machine Design; Maskinkonstruktion;

    Sammanfattning : The transportation system is undergoing a transformation to enable socially, environmentally, and economically sustainable transport solutions, and driverless trucks are considered one innovation that can contribute to a more sustainable and efficient transportation system. Nevertheless, introducing driverless trucks will cause disruptions in the system, and one considerable change is that the driver is no longer present. LÄS MER

  7. 5. Design of Multifunctional Body Panels in Automotive Applications : Reducing the Ecological and Economical footprint of the vehicle industry

    Författare :Christopher John Cameron; Dan Zenkert; Peter Göransson; Per Wennhage; Per-Olof Sturesson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sandwich panels; mutifunctional; structural acoustic interaction; NVH; vehicle acoustics; Vehicle engineering; Farkostteknik;

    Sammanfattning : Over the past century, the automobile has become an integral part of modern industrializedsociety. Consumer demands, regulatory legislation, and the corporate need togenerate a profit, have been the most influential factors in driving forward the evolutionof the automobile. LÄS MER
