  1. 11. Individual Failure Rate Modelling and Exploratory Failure Data Analysis for Power System Components

    Författare :Jan Henning Jürgensen; Lars Nordström; Patrik Hilber; Miguel Angel Sanz Bobi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asset management; condition monitoring; failure rate; failure rate modeling; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A set of vital societal functions such as health and safety are necessary for today's society to function and to secure the life of its individuals. Infrastructure is required to provide and maintain these functions. LÄS MER

  3. 12. Living Away from Blessings : School Failure as Lived Experience

    Författare :Carina Henriksson; Solveig Hägglund; Växjö universitet; []
    Nyckelord :school failure; lived experience; lived experience description.; temporality; spatiality; relationality; cognitive inadequacy; behavioral deficiency; the hidden curriculum; hermeneutic phenomenology; phenomenology of practice; Pedagogik; Pedagogics;

    Sammanfattning : This dissertation seeks to unveil and describe students’ experiences of school failure. Traditionally, research in the field has tended to approach school failure from a societal perspective, often construing school failure as a drop-out problem. LÄS MER

  4. 13. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

    Författare :Dalius Misiunas; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; reglerteknik; robotteknik; Automatiska system; Water supply; failure; detection; monitoring; location; bursts; hydraulics; leakage; asset management; condition assessment; pipelines; pipe networks; Automation; control engineering; robotics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. LÄS MER

  5. 14. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure

    Författare :Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

    Sammanfattning : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.

  7. 15. On dental implant failure and patient-related factors

    Författare :Malin Olsson Malm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implants; implant failure; long term; implant surface; multivariable logistic regression; case-control study; edentulous jaw; gene expression analysis; early implant failure; patient factors;

    Sammanfattning : Dental implants function as anchorage for dental prostheses. In a small number of cases, osseointegration fails to establish or be maintained around the implants, but the reasons for these failures are not yet fully understood. LÄS MER
