  1. 21. Overall Accessibility of Public Transport for Older Adults

    Författare :Catherine Sundling; Mats E. Nilsson; Birgitta Berglund; Leslie R. Pendrill; Ragne Emardson; Bo Edvardsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; older persons; critical incidents; critical reactions; travel behavior; accessibility; functional limitation; functional ability; barrier; facilitator; public transport; railway travel; Psychology; psykologi;

    Sammanfattning : This thesis is based on four studies that explore accessibility for older adults during whole trips by public transport. The overall goal was to gain knowledge of the interrelationships among key variables and to develop a conceptual model of the overall accessibility of public transport. LÄS MER

  3. 22. Understanding the Impacts of Weather and Climate Change on Travel Behaviour

    Författare :Liu Chengxi; Yusak O. Susilo; Karlström Anders; Kelly J. Clifton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impacts of weather; climate change; travel survey; spatial heterogeneity; activity-travel pattern; weather perception; passenger transport CO2 emission; Transportvetenskap; Transport Science;

    Sammanfattning : Human behaviour produces massive greenhouse gas emissions, which trigger climate change and more unpredictable weather conditions. The fluctuation of daily weather corresponds to variations of everyday travel behaviour. This influence, although is less noticeable, can have a strong impact on the transport system. LÄS MER

  4. 23. Perceived Accessibility : Capturing the Traveller Perspective

    Författare :Katrin Lättman; Margareta Friman; Lars E Olsson; Annika Nordlund; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; perceived accessibility; accessibility scale; transport planning; public transport; social inclusion; social exclusion; Psykologi; Psychology;

    Sammanfattning : The main purpose of this thesis is introducing and proposing perceived accessibility as an important and so far overseen complement to conventional, objective accessibility in sustainable transport. Perceived accessibility is defined as the possibilities and ease of engaging in preferred activities using different transport modes. LÄS MER

  5. 24. Towards Supervisory control for complex Propulsion subsystems

    Författare :Dhinesh Vilwanathan Velmurugan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Powertrain subsystem complexity has been on the rise with increasing legal requirements and meeting disruptive market trends. There is greater potential for cost efficient robust operation with integrated control units and software development. LÄS MER

  7. 25. Martensitic Transformations in Steels : A 3D Phase-field Study

    Författare :Hemantha Kumar Yeddu; John Ågren; Annika Borgenstam; Yunzhi Wang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; Martensitic transformations; Plastic de formation; Multi-length scale modeling; Microstructure; Stress states; Steels;

    Sammanfattning : Martensite is considered to be the backbone of the high strength of many commercial steels. Martensite is formed by a rapid diffusionless phase transformation, which has been the subject of extensive research studies for more than a century. LÄS MER
