  1. 16. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures

    Författare :Christian Öberg; Stefan Jonsson; Henrik Östling; KTH; []
    Nyckelord :creep; constant-load; thermal cycling; tensile test; cast materials; cast iron; exhaust materials.; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms.

    Sammanfattning : This thesis consists of an introduction and seven appended papers. The purpose of the introduction is to give an overview of the field of topology optimization of discretized load carrying continuum structures. LÄS MER

  4. 18. Testing principles from cognitive behavior therapy for preventing stress-related ill health among newly registered nurses

    Författare :Elin Frögéli; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Transitioning from education to working life is a challenging endeavor and newly registered nurses are one professional group that report high levels of symptoms of stress-related ill health. Transition-to-practice programs that are developed to support newly registered nurses’ professional adjustment have not been found to be effective in preventing these experiences. LÄS MER

  5. 19. Prediction-driven decision rules, RCT design and survival analysis

    Författare :Adam Brand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Predictions are becoming more and more a part of our lives, and they are becoming increasingly useful in medical science as the science evolves. Increased understanding of disease and its treatments allows us to use predictions based on predictive biomarker signatures to optimize treatment outcomes for increasingly granular subject groups.

  7. 20. Contactless Test of Circuit Boards

    Författare :Abdelghani Renbi; Heli Jantunen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Electronics are still continuing to respond to the small-feature size requirement for economical, performance and environmental benefits.Due to the non-idealities in the manufacturing process of circuit boards, electronics production yield is never 100 %. LÄS MER
