5. 4. The Significance of Things Affective User-Artefact Relations

   Detta är en avhandling från Chalmers tekniska högskola

   Författare :Viktor Hiort af Ornäs; Viktor Hjort af Ornäs; Högskolan i Skövde.; Högskolan i Skövde.; [2010]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; User-centred desig; User experience; Significant things; Significant use; Significant consequences; User-centred design;

   Sammanfattning : Products help people act, but also thrill, excite, and elicit fear, joy and anger. Artefacts are a natural part of people’s everyday lives, sometimes associated with values, dreams and aspirations. While traditional user-centred approaches have focused on efficiency and effectiveness of use, injury prevention etc. LÄS MER

7. 5. On Thermal Conductivity and Strength in Compacted Graphite Irons : Influence of Temperature and Microstructure

   Detta är en avhandling från Göteborg : Chalmers Reproservice

   Författare :Martin Selin; Högskolan i Jönköping.; [2010]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Compacted Graphite Iron; Thermal Conductivity; Mechanical Properties; Hardness; Microstructure; Plastic Deformation; Hollomon Equation; Elevated Temperature;

   Sammanfattning : Thermal conductivity, hardness and strength are all highly important material properties, affecting the performance and life expectancy of components operating at elevated temperatures. The main purpose of this work has been to increase the knowledge and understanding concerning how mechanical and physical properties are affected by temperature and microstructure in compacted graphite irons.
