  1. 21. Från järnvägsstation till kommunikationsnod

    Författare :Aram Bakerson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : AbstractIn organizational terms train stations were for a long period of time a component of railway transportation. Therefore during the crisis period for railways after the Second World War the stations did not often receive the attention and the resources they deserved. LÄS MER

  3. 22. Group work and physics – characteristics, learning possibilities and patterns of interaction

    Författare :Maria Berge; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; higher education; phenomenography; conversation analysis; multi-theoretic perspective; science education; engineering education; physics education; group work; variation theory; positioning theory;

    Sammanfattning : This thesis explores group work in physics at university level. The guiding research interest is what happens in the students’ interactions during such (instructional) activities, focusing both on the physics content and group dynamics. LÄS MER

  4. 23. Qualification Aspects in Design for Additive Manufacturing : A Study in the Space Industry

    Författare :Christo Dordlofva; Anna Rönnbäck Öhrwall; Peter Törlind; Ola Isaksson; Carolyn Conner Seepersad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Design for Additive Manufacturing; Qualification; Design for Qualification; Space Industry; Produktinnovation; Product Innovation;

    Sammanfattning : The aim of this research is to further the understanding of implications for product development and qualification when introducing additive manufacturing (AM) in the context of the space industry. Increased availability of AM machines and alluring potentials such as design freedom and cost-efficient product development and manufacturing has led to a rapid growth in the use of AM.

  5. 24. Intentional electromagnetic interference (IEMI) : Susceptibility investigations and classification of civilian systems and equipment

    Författare :Daniel Månsson; Rajeev Thottappillil; Mats Bäckström; William Radasky; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic compatibility; Intentional electromagnetic interference; High power electromagnetic; Other engineering physics; Övrig teknisk fysik;

    Sammanfattning : This PhD thesis addresses the threat posed to society by sources that can produce high power electromagnetic pulses (HEPM) and be used maliciously to disturb or damage electronic equipment. The vulnerability from intentional electromagnetic interference (IEMI) has increased in the recent decades due to the widespread dependence of the civil society on sensitive electronic systems and proliferation of radiation sources.

  7. 25. Navigating Sustainability Transformations: Backcasting, transdisciplinarity and social learning

    Författare :Johan Holmén; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; backcasting; transformations; systems change; social learning; Education for Sustainable Development ESD ; Sustainability; transitions; reflexive governance; transdisciplinarity;

    Sammanfattning : Complex and persistent sustainability challenges necessitate transformations into futures that are fundamentally different to what was before. Such change processes cannot be planned in traditional ways; they require reflexive modes of governing where we collectively learn how to navigate uncharted terrain while exploring it. LÄS MER
