  1. 21. High-Temperature Durability Prediction of Ferritic-Martensitic Steel

    Författare :Ahmed Azeez; Robert Eriksson; Kjell Simonsson; Daniel Leidermark; Christer Persson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ferritic-martensitic steel; Low cycle fatigue; Thermomechanical fatigue; Crack propagation; Fracture mechanics; Finite element modelling;

    Sammanfattning : Materials used for high-temperature steam turbine sections are generally subjected to harsh environments with temperatures up to 625 °C. The superior creep resistance of 9–12 % Cr ferritic-martensitic steels makes them desirable for those critical steam turbine components. LÄS MER

  3. 22. High-Temperature Fatigue in a Steam Turbine Steel : Modelling of Cyclic Deformation and Crack Closure

    Författare :Ahmed Azeez; Robert Eriksson; Kjell Simonsson; Daniel Leidermark; Magnus Hörnqvist Colliander; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Existing conventional thermal power plants are retrofitted for flexible operations to assist the transition toward more renewable energies. The deployment of many renewable energy power plants is necessary to achieve a clean environment with less pollution. LÄS MER

  4. 23. Estimation of hazard ratios from observational data with applications related to stroke

    Författare :Guilherme Barros; Jenny Häggström; Marie Eriksson; Daniel Nevo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; survival analysis; causal inference; hazard ratios; marginal hazard ratio; stroke; balancing; Statistics; statistik;

    Sammanfattning : The objective of this thesis is to examine some challenges that may emerge when conducting time-to-event studies based on observational data. Time-to-event (also called survival) is a setting that involves analyzing how different factors may influence the length of time until an individual experiences the event of interest. LÄS MER

  5. 24. Sustainable Interactions : Studies in the Design of Energy Awareness Artefacts

    Författare :Loove Broms; Magnus Bång; Henrik Eriksson; Daniel Fällman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interaction design; energy awareness; sustainability; domestication; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents a collection of experimental designs that approach the problem of growing electricity consumption in homes. From the perspective of design, the intention has been to critically explore the design space of energy awareness artefacts to reinstate awareness of energy use in everyday practice. LÄS MER

  7. 25. A Systems View of Advancements in Biomass Supply Chains

    Författare :Johanna Enström; Aron Larsson; Leif Olsson; Lars Eliasson; Anders Eriksson; Daniel Nilsson; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry logistics; Supply Chain Management; Discrete Event Simulation; Forest fuel;

    Sammanfattning : Forest fuel is an important source of energy with potential for increased use in the Nordic countries. Profitable forest operations are dependent on logistics as the forest is a natural resource with varying conditions over widespread areas. LÄS MER
