    Sammanfattning : Over the last decade, a great variety of visionary ideas and beliefs have been brought forward, regarding the potentials of using computer games as a tool for learning and mediation in educational settings. This thesis aims at contributing to research in this field, by empirically exploring what happens when students play and reflect on their computer game play in science education. LÄS MER

  3. 2. Metabolic variation in autoimmune diseases

    Sammanfattning : The human being and other animals contain immensely complex biochemical processes that govern their function on a cellular level. It is estimated that several thousand small molecules (metabolites) are produced by various biochemical pathways in humans. LÄS MER

  4. 3. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Författare :Pajazit Avdovic; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER

  5. 4. Machinability variations in alloy 718 turbine components

    Författare :Pajazit Avdovic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation in tool; hardness; Machining; flank wear; notch wear; alloy 718; grain size; instability; variation in material;

    Sammanfattning : Machinability Variations in Alloy 718 Turbine Components PAJAZIT AVDOVIC Department of Materials and Manufacturing TechnologyChalmers University of Technology AbstractAlloy 718 has a reputation for being very troublesome during the cutting process. It was suspected that this material was too hard and having too fine grain size and that these characteristics caused damage to cutting tools during processing. LÄS MER

  7. 5. Eliciting Knowledge from Experts in Modeling of Complex Systems : Managing Variation and Interactions

    Författare :Per Wikberg; Bo Strangert; Erland Svensson; Berndt Brehmer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modeling; Experts; Communication; Qualitative Data; Roles; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : The thematic core of the thesis is about how to manage modeling procedures in real settings. The view taken in this thesis is that modeling is a heuristic tool to outline a problem, often conducted in a context of a larger development process. LÄS MER
