  1. 21. A methodology for situated and effective design of haptic devices

    Författare :Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Sammanfattning : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  2. 22. Simplified Life Cycle Assessment Approaches and Potential Impact Shifts

    Författare :Katja Tasala Gradin; Sofia Ritzén; Anna Hedlund-Åström; Matthias Finkbeiner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA simplification approach; impact shift; reduction measures; road transport; streamlining; screening; Machine Design; Maskinkonstruktion;

    Sammanfattning : Road transport contributes to approximately one quarter of all EU greenhouse gas emissions and is the leading cause of air pollution in cities. There are significant measures aimed at the reduction of use phase environmental impacts; in the EU, these strategies focus on the decarbonisation of road transport, such as through the prioritization of low- and zero-emission vehicles.

  3. 23. Thermal Barrier Coatings for Diesel Engines

    Författare :Anders Thibblin; Ulf Olofsson; Stefan Jonsson; Senad Dizdar; Uta Klement; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; diesel engine; thermal cycling fatigue; heat flux; running-in; exhaust manifolds; yttria-stabilized zirconia; gadolinium zirconate; lanthanum zirconate; Machine Design; Maskinkonstruktion;

    Sammanfattning : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.

  5. 25. Understanding the system-level for Mobility as a Service : A framework to evaluate full-scale impacts of MaaS

    Författare :Bhavana Vaddadi; Anna Pernestål Brenden; Yusak Susilo; Mia Xiaoyun Zhao; Jeppe Rich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility as a Service; system-level; perspective; framework; experiments; Machine Design; Maskinkonstruktion;

    Sammanfattning : Mobility as a Service (MaaS), as a concept, has been widely popularised and considered to hold promising potential in reducing travel-related environmental impacts and transforming our current transport system. MaaS enables intermodal travel by providing enhanced features for users to access multiple mobility services. LÄS MER
