Modeling of anisotropic viscoelastic fluids
 Šípka, Martin ; Tůma, Karel (advisor) ; Průša, Vít (referee)
In this thesis, we aim to create a framework for the derivation of thermodynamically consistent anisotropic viscoelastic models. As an example we propose simple models extending the isotropic Oldroyd-B and Giesekus models to illustrate the models' behavior and the process of finding the correct equations. We show what behavior in sheer we can expect and continue with a 3D simulation inspired by the experiment on a real liquid crystal mixture. Finally, we compare the simulation and the experiment to find similarities and possible further research topics.

Gravitational collapse of scalar field
 Šípka, Martin ; Ledvinka, Tomáš (advisor) ; Scholtz, Martin (referee)
In this thesis we study a critical collapse of a scalar field. We follow the work of [1] and create detailed and easy to understand figures and images describing the results and the phenomena observed during our calculations. We also try to give a detailed look at numerical methods used along with two ways of convergence testing. 1
