Emin Mert Sunacoglu: Inverse Problems in elasticity

Bachelor's thesis submission talk. Emin is advised by Anne Reinarz.

The elasticity theory describes the reversible deformation, which is defined as the displacement on a solid object, caused by an external factor like heat, force or magnetism and reversed when the external factor is removed. The elasticity theory can be used to simulate earthquakes and calculate the spread of the waves. We can also use the elasticity theory to make accurate models for earthquakes. These models, combined with the real world data that can be sampled from existing earthquakes, can be used for predicting the variables, like material parameters of earth. We can use either bayesian approach for solving this problems, which treats the parameters as probability distributions or we can use adjoint methods to use the gradients in order to solve the inverse problem.

Keywords: Elasticity theory, inverse problems, markov chain monte carlo, adjoint methods
