  1. 21. Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications

    Författare :Miriam Kemm; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; applied thermodynamics; Termisk teknik; Transient analysis; Technological sciences; Teknik; Energy research; Energiforskning; Thermal engineering; Thermal stress; Solid Oxide Fuel Cell; Fuel cell modelling;

    Sammanfattning : Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. LÄS MER

  3. 22. Planning of Environments for People with Physical Disabilities Using Computer Aided Design

    Författare :Joakim Eriksson; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manikin; Virtual Reality; CAD; computer aided design; 3D graphics; design tool; participatory planning; adaptation; Rehabilitation; disability; anthropometry; Technological sciences; magnetic resonance imaging; MRI; cervical spine kinematics; Teknik; biomechanics;

    Sammanfattning : In the area of environment adaptations for people with physical disabilities, it is of vital importance that the design is optimized considering the human-environment interactions. All involved persons in such a planning process must be given sufficient support in understanding the information, so that everyone can participate actively. LÄS MER

  4. 23. Adding Audibility - Reifying the Soundscape of Process Operators

    Författare :Petter Alexanderson; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technological sciences; Samhällsvetenskaper; Social sciences; systemteori; Informatik; systems theory; Informatics; Process Control; Acoustic Ecology; Interaction Design; Auditory Interaction; Teknik;

    Sammanfattning : A contemporary challenge when designing interactive artifacts is to take into account the wealth of devices, systems, and tools people use every day - here termed an 'interaction ecology'. This thesis addresses three research issues. Firstly, the character of sound perception, and how auditory interaction can be applied to ubiquitous computing. LÄS MER

  5. 24. Strength and Stability of Interfaces in Cemented Carbides

    Författare :Mikael Christensen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adhesion; segregation; plastic deformation; microstructure; interfaces; electron structure calculations; cermets; sintering; infiltration; cemented carbides; grain boundaries; cutting tools; density-functional theory; hardmetals; WC-Co; wetting;

    Sammanfattning : Cemented carbides are hard composite materials of great technological importance. They are widely used as tool materials in a large variety of applications where the demands on hardness and toughness are high, including e.g.≈mining, turning, cutting, and milling. LÄS MER

  7. 25. Finite Element Procedures in Modelling the Dynamic Properties of Rubber

    Författare :Anders K Olsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; akustik; vibration and acoustic engineering; Materiallära; materialteknik; Mechanical engineering; hydraulics; vacuum technology; Material technology; dynamic; amplitude; frequency; Technological sciences; Teknik; FEM; rubber; vibrationer; vakuumteknik; Maskinteknik; hydraulik;

    Sammanfattning : Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. LÄS MER
