  2. 6. Estimation of hazard ratios from observational data with applications related to stroke

    Author : Guilherme Barros; Jenny Häggström; Marie Eriksson; Daniel Nevo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; survival analysis; causal inference; hazard ratios; marginal hazard ratio; stroke; balancing; Statistics; statistik;

    Abstract : The objective of this thesis is to examine some challenges that may emerge when conducting time-to-event studies based on observational data. Time-to-event (also called survival) is a setting that involves analyzing how different factors may influence the length of time until an individual experiences the event of interest. READ MORE

    Abstract : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. READ MORE

  6. 9. An Ontological Approach to Safety Analysis of Safety-Critical Systems

    Author : Jiale Zhou; Kristina Lundqvist; Ibrahim Habli; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hazard analysis; ontologies; safety-critical systems; safety requirements elicitation; Computer Science; datavetenskap;

    Abstract : Safety-critical systems (SCSs) have become an intrinsic part of human dailylife in multiple domains, such as automotive, avionics, and rail industries. Such systems are not only required to implement the functionality they should provide, but also have to satisfy a set of safety requirements in order to ensure the mitigation of hazardous consequences.
