  1. 16. Incorporating Functional Safety in Model-based Development of Product Lines

    Författare :Stephan Baumgart; Sasikumar Punnekat; Rolf Johansson; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Product lines in industry are often based on an engineer’s focus on fast and feasible product instantiation rather than a precise product line development method and process as described in literature. When considering functional safety, we need a precise model that includes evidence for the safety of each variant of the product. LÄS MER

  2. 17. Uncertainty quantification for high frequency waves

    Författare :Gabriela Malenova; Olof Runborg; Fabio Nobile; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : We consider high frequency waves satisfying the scalar wave equation with highly oscillatory initial data represented by a short wavelength ε. The speed of propagation of the medium as well as the phase and amplitude of the initial data is assumed to be uncertain, described by a finite number of independent random variables with known probability distributions.

  3. 18. Novel strategies to explore The complex genetics of autoimmune diseases

    Författare :Martina Johannesson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunology; serology; Immunologi; serologi; cytogenetik; Genetik; cytogenetics; Genetics; collagen induced arthritis; QTL mapping; complex traits; autoimmunity; genetics;

    Sammanfattning : Autoimmune diseases are dependent on both genetic and environmental factors in complex interplay. They arise from a faulty immune response against self-antigens, and causes great suffering in affected individuals. Despite large efforts and hundreds of thousands of research articles published, the disease etiologies remain largely unknown. LÄS MER

  4. 19. Reliability-based design of rock tunnel support

    Författare :William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. LÄS MER

  5. 20. Learning for safety in health care and air traffic control

    Författare :Sven Ternov; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Risk management; accident models; complex systems; health care; air traffic control; MTO analysis; DEB-analysis; proactive risk analysis.;

    Sammanfattning : Introduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error.
