[Cancelled]CIVL Departmental Seminar - Selected Developments in Uncertainty Quantification in Engineering
3:00pm - 4:00pm
Room 3574, Academic Building (near Lifts 27-28)

Our structures, systems and infrastructure are characterized by a rapid growth in scale, complexity and interconnection with a significant involvement of diverse human behavior with critical influence, so that uncertainties and risks are involved to a greater extent than ever before. These structures, systems and infrastructure are, to a significant extent, critical for the functionality of our economic and societal life, and thus, require proper approaches and measures to verify and ensure their reliable performance. Reliability and performance analysis, however, become increasingly complicated due to uncertainties and complexity. The realistic quantification of uncertainties and their numerically efficient processing in complex analyses are the two key challenges in this context. In this seminar we discuss emerging concepts and approaches which address these challenges in three conceptual directions. First, new pathways in advanced stochastic modeling are elucidated with focus on joint time-frequency analysis utilizing wavelet transform. Second, advancements in generalized uncertainty modelling for coping with limited and vague information, with focus on imprecise probabilities, are presented. Third, selected potent Monte Carlo techniques, including line sampling, for numerically efficient simulation are discussed. The three conceptual directions are discussed in a coherent context of uncertainty quantification, which also includes combinations of the different developments. Examples are provided for a range of applications, which demonstrate the capabilities of the discussed developments as well as the potential generated by their combinations.
