  2. 1. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

    Author : Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. READ MORE

  4. 2. Cost-Benefit Analysis of Separation Distances - a utility-based approach to risk management decision-making

  6. 4. Utilities and quality of life in cardiovascular disease : drivers, economic effects and clinical outcomes

    Author : Jenny Berg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Atrial fibrillation and chronic heart failure represent important contributors to cardiovascular disease burden, with high incidence, prevalence and mortality rates. The overall objective of this thesis is to enhance the knowledge on what drives preferences for different health st ates (utilities) in patients with atrial fibrillation and chronic heart failure, and how health-related quality of life and utilities in turn influence clinical and economic outcomes.
