  4. 2. Incorporating the end-of-life aspect into product development : analysis and a systematic approach

    Author : Jörgen Furuhjelm; Jan-Gunnar Persson; Linköpings universitet; []
    Keywords : ;

    Abstract : It is evident that we face a major challenge to overcome the environmental problems associated with our consumption and production systems. The rate at which products flow through our society is steadily increasing and this leads to serious consequences in the form of accelerating depletion of the earth's resources and generation of enormous amounts of waste.

  5. 3. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs

    Author : Hussan Hamodi; Jan-Gunnar Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. READ MORE

  6. 4. Model for End of Life Treatment of Polymer Composite Materials

    Author : Anna Hedlund-Åström; Jan-Gunnar Persson; Conrad Luttropp; Sigbritt Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; material recycling; energy recovery; environmental effects; recommendations; waste treatment model; Environmental engineering; Miljöteknik;

    Abstract : Because of increasing environmental demands, especially on dealing with products end of life phase, product manufacturers and designers must consider the future disposal of their products. For conventional materials like steel and aluminium well-functioning recycling methods exists. READ MORE

  7. 5. On the modular modelling for dynamical simulation with application to fluid systems

    Author : Carl-Johan Sjöstedt; Jan-Gunnar Persson; Petter Krus; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : This licentiate thesis highlights some topics on modular modelling for dynamical simulation with application to fluid systems. The results are based on experience from the development of the fuel cell component simulation environment NFCCPP. The general application is cross-enterprise simulation of technical systems.
