  1. 1. Eliciting User Experience Information in Early Design Phases. The CARE Approach to In-Vehicle UX

    Författare :Ingrid M Pettersson; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; user experience; evaluation; in-vehicle; autonomous vehicles; UX; design methods;

    Sammanfattning : Experience-rich input in early phases of a design process can offer valuable information and inspiration to designers. However, there are methodological challenges linked with efforts to understand future user experiences. LÄS MER

  3. 2. The temporality of in-vehicle user experience: exploring user experiences from past to future

    Författare :Ingrid M Pettersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Temporality; Future; User Experience; Over Time; Human Machine Interaction; Automotive; Design; Methodology; In-Vehicle Systems;

    Sammanfattning : Cars are nowadays equipped with numerous interactive systems, aiding the driver by providing safety warnings, driving information, support, connectivity and entertainment. Traditionally in the field of in-vehicle system design, the focus of the automotive industry been on safety, i.e. on distraction measures and usability. LÄS MER

  4. 3. tRNA Gene Structures in Bacteria

    Författare :B. M. Fredrik Pettersson; Leif A. Kirsebom; Anders Byström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : In bacteria, tRNA molecules are produced as precursors with additional nucleotides both upstream and downstream of the tRNA coding sequence. To generate a mature tRNA, the endoribonuclease RNase P removes the upstream sequence, while a number of enzymes can remove the downstream sequence. LÄS MER

  5. 4. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner

    Författare :Annika Pettersson; Igor Gachkov; Kerstin Pettersson; Lovisa Sumpter; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; linear function; graphic representation; scale; concept image; Matematik; Mathematics;

    Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER

  7. 5. Lubrication and Surface Properties of Adsorbed Layers of Polyelectrolytes and Proteins

    Författare :Torbjörn Pettersson; Per M. Claesson; Hans-Jürgen Butt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biochemistry; biomedical engineering; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : Friction forces between protein / polyelectrolyte layers, adsorption properties of proteins, and conformational changes due to variation in electrolyte concentration have been investigated. The aim was to obtain better understanding of adsorbed layer properties, with focus on the relation between layer structure and lubrication capabilities. LÄS MER
