  1. 11. Metaphor in Mind : Programming Teachers' Knowledge and Beliefs in Action

    Författare :Andreas Larsson; Konrad Schönborn; Jesper Haglund; Jonas Hallström; Niall Seery; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Conceptual Metaphor; Speech and Gesture; Programming Education; Technology; Konceptuella metaforer; Gestanalys; Programmeringsundervisning; Teknik;

    Sammanfattning : Programming has become an integral component of technology education around the world and is an important part of Swedish curriculum reform and classroom teaching. This thesis aims to explore relations between programming teachers' knowledge and beliefs about programming teaching and how it is enacted in their practice. LÄS MER

  3. 12. Microstructure and Wear of CVD Coatings used in Metal Cutting Applications

    Författare :Andreas Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MTCVD; Ca-treated steel; EFTEM; CVD; TEM; Ti C; alfa-Al2O3; gamma-Al2O3; wear; kappa-Al2O3; N ; EELS;

    Sammanfattning : This thesis is concerned with the microstructural characterisation of wear resistant Al2O3 and Ti(C,N)coatings produced by chemical vapour deposition on cemented carbide cutting tools. The investigation focuses on the effect of deposition conditions on the microstructure and the microstructural evolution of the coatings during heat-treatments and metal cutting. LÄS MER

  4. 13. Security and Self-stabilization in Sensor Network Services

    Författare :Andreas Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clock-synchronization; Secure and Resilient Computer Systems; Ad-hoc Networks; Self-Stabilization; Sensor-Network Systems; Clustering;

    Sammanfattning : Wireless sensor networks consist of small sensor nodes that monitor their environment and that together can cover vast geographical regions. It is a promising field with many possible applications in different application areas. Typically the nodes do not have any preexisting information about the network topology when deployed. LÄS MER

  5. 14. Synthesis, structure and conformation of oligo- and polysaccharides

    Författare :Andreas Larsson; Göran Widmalm; Laurence Mulard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : Carbohydrates are a complex group of biomolecules with a high structural diversity. Their almost omnipresent occurrence has generated a broad field of research in both biology and chemistry. This thesis focuses on three different aspects of carbohydrate chemistry, synthesis, structure elucidation and the conformational analysis of carbohydrates. LÄS MER

  7. 15. Towards Secure and Self-stabilizing Sensor Network Services for Civil Security

    Författare :Andreas Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Wireless sensor networks, consisting of a vast number of small sensor nodes that can monitor large areas, are a promising field with many possible applications in many different application areas. In civil security settings, e.g. LÄS MER
