101-0178-01L	Uncertainty Quantification in Engineering	W	3 KP	2G	S. Marelli, B. Sudret
Kurzbeschreibung	Uncertainty quantification aims at studying the impact of aleatory and epistemic uncertainty onto computational models used in science and engineering. The course introduces the basic concepts of uncertainty quantification: probabilistic modelling of data (copula theory), uncertainty propagation techniques (Monte Carlo simulation, polynomial chaos expansions), and sensitivity analysis.
Lernziel	After this course students will be able to properly pose an uncertainty quantification problem, select the appropriate computational methods and interpret the results in meaningful statements for field scientists, engineers and decision makers. The course is suitable for any master/Ph.D. student in engineering or natural sciences, physics, mathematics, computer science with a basic knowledge in probability theory.
Inhalt	The course introduces uncertainty quantification through a set of practical case studies that come from civil, mechanical, nuclear and electrical engineering, from which a general framework is introduced. The course in then divided into three blocks: probabilistic modelling (introduction to copula theory), uncertainty propagation (Monte Carlo simulation and polynomial chaos expansions) and sensitivity analysis (correlation measures, Sobol' indices). Each block contains lectures and tutorials using Matlab and the in-house software UQLab (www.uqlab.com).
Skript	Detailed slides are provided for each lecture. A printed script gathering all the lecture slides may be bought at the beginning of the semester.
Voraussetzungen / Besonderes	A basic background in probability theory and statistics (bachelor level) is required. A summary of useful notions will be handed out at the beginning of the course. A good knowledge of Matlab is required to participate in the tutorials and for the mini-project.

402-0395-00L	Multimessenger Constraints of Generalizations of Gravity Findet dieses Semester nicht statt.	W	8 KP	3G	L. Heisenberg
Kurzbeschreibung	The LIGO detections of Gravitational Waves have started the field of Gravitational Wave astronomy. This opens an exiting opportunity to test gravity theories in regimes where it has not been tested yet. Together with standard cosmological observations, one can put tight multimessenger constraints on different cosmological models.
Lernziel	These lecture series will be dedicated to combining theory with cosmological observations. First of all, I will discuss the consistent construction of prominent gravity theories, both from a geometrical as well as field theory perspectives. I will introduce more general space-time geometries as well as the building blocks of field theories based on additional degrees of freedom in the gravity sector. Coming from the theory side, I will explain the theoretical constraints and consistency checks that can be applied to fundamental gravity theories. In the observational side, the confrontation of gravity theories with cosmological observations is a crucial ingredient in testing these theories. A natural starting point will be the study of the background evolution. Theory parameters can then be constrained using the distance redshift relation from Supernovae, the distance priors method from CMB and BAO measurements. Given the recent developments in gravitational wave physics, I will discuss the implications of alternative gravity theories in the regime of strong gravity.

Kurzbeschreibung	This course gives an introduction to the interaction of mechanical motion with electromagnetic fields in the quantum regime.
