  2. 21. Determination of Material Properties for Fire Modelling

    Author : Ulf Göransson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

    Abstract : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. READ MORE

  4. 22. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

    Author : Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

    Abstract : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. READ MORE

  5. 23. Eutectic Modification of Al-Si casting alloys

    Author : Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. READ MORE

  6. 24. Computational Material Design : Diluted Magnetic Semiconductors for Spintronics

    Author : Lunmei Huang; Rajeev Ahuja; Walter Temmerman; Uppsala universitet; []
    Keywords : Physics; Density functional theory; Diluted magnetic semiconductor; Ferromagnetism; Defect; Phase transition; High pressure; Thermal elastic constant; Fysik;

    Abstract : The present thesis deals with the application of ab-initio electronic structure calculations based on density functional theory for material design.The correlation between magnetic properties and electronic structures has been investigated in detail for diluted magnetic semiconductors (DMS), which have promising application for spintronics devices.

  7. 25. Socio-material mediations : learning, knowing and self-produced media within healthcare

    Author : Erling Björgvinsson; Malmö högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Interaction design; workplace studies; Interactive media;

    Abstract : The thesis discusses lessons learned and issued raised when exploring how self-produced rich media can facilitate sharing of meaning between healthcare professionals at an intensive care unit and between healthcare professionals and patients within a hand surgery clinic. Design experiments conducted at the intensive care unit focused on how healthcare professionals could collaboratively produce ‘best practice’ videos displayed on handheld devices and accessed through barcodes placed out in the unit.
