  1. 16. Probabilistic design for evaluation of indoor environment

    Författare :Katarina Ljungquist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : In recent years indoor environment and indoor air quality has been subjected to extensive worldwide research efforts. Still, at present there are a lack of methods for prediction of risks and consequences for any defined damage to occur, similar to the probabilistic methods used in modern design codes for structures and buildings.

  3. 17. Simulation-Driven Development for Increased System Reliability

    Författare :Jonas Pavasson; Lars Drugge; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The product development process at industrial companies has traditionally focused on hardware-oriented solutions. However, a current trend is to extend business offers to include more service-oriented solutions e.g., functional product business models. LÄS MER

  4. 18. Modelling and simulation of support systems to predict operational availability

    Författare :Petter Kyösti; Martin Helgoson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The aim of the work presented in this thesis is the development of the tools that support industry in offering FPs as a viable business case. A support system modelling and simulation tool, such as the one demonstrated in this thesis, would improve the possibilities of developing the support system early, concurrently with the development of the hardware.

  5. 19. Development and application of high voltage dielectric spectroscopy for diagnosis of medium voltage XLPE cables

    Författare :Peter Werelius; KTH; []
    Nyckelord :dielectric spectroscopy; high voltage; variable frequency; diagnostics; non-disgnostics;

    Sammanfattning : When polymer power cables were introduced into mediumvoltage applications in the late 1960s, the degradationphenomenon later referred to aswater treeingwas still unknown. However, this changedwithin a relatively short space of time. LÄS MER

  7. 20. Aircraft Systems Conceptual Design : An object-oriented approach from to

    Författare :Ingo Staack; Petter Krus; Frank Thielecke; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.
