1. 1. New ways of learning : Participatory action research and Kenyan runners’ appropriation of smartphones to improve their daily lives and participation in m-learning

   Författare :Per-Olof Hansson; Per Andersson; Elin Wihlborg; Rodderick Fox; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Participatory action research; m-learning; sociocultural perspective; Deltagande aktionsforskning; mobilt lärande; sociokulturellt perspektiv;

   Sammanfattning : In Kenya, mobile technology is widely used, with more and more people gaining access to the Internet. Mobile technology has the potential to support learning and improve lives, particular those of impoverished people. In this study, 30 Kenyan runners from poor backgrounds and with limited formal education participated. LÄS MER

3. 2. Technological knowledge and technology education

   Författare :Per Norström; Sven Ove Hansson; Per Sandin; Peter Kroes; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; philosophy of technology; epistemology of technology; technology education; technological knowledge; rule of thumb; explanation; Filosofi; Philosophy;

   Sammanfattning : Technological knowledge is of many different kinds, from experience-based know-how in the crafts to science-based knowledge in modern engineering. It is inherently oriented towards being useful in technological activities, such as manufacturing and engineering design. LÄS MER

4. 3. Technology education and non-scientific technological knowledge

   Författare :Per Norström; Sven Ove Hansson; Per Sandin; Inga-Britt Skogh; Ibo van de Poel; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; rule of thumb; technical knowledge; technological knowledge; technology education; epistemology of technology; design process; modelling;

   Sammanfattning : This thesis consists of two essays and an introduction. The main theme is technological knowledge that is not based on the natural sciences.The first essay is about rules of thumb, which are simple instructions, used to guide actions toward a specific result, without need of advanced knowledge.

5. 4. First determination of the electric charge of the top quark

   Författare :Per Hansson; Bengt Lund-Jensen; Peter Hansen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : In this thesis, the first determination of the electric charge of the top quark is presented using 370pb-1 of data recorded by the DØ detector at the Fermilab Tevatron accelerator. ttbar events are selected with one isolated electron or muon and at least four jets out of which two are b-tagged by reconstruction of a secondary decay vertex (SVT).

7. 5. Numerical Modelling of Short Fatigue Crack Growth

   Författare :Per Hansson; Mekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete dislocation; Fatigue; grain boundary; short crack;

   Sammanfattning : Fatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. LÄS MER
