Application of boundary value problems for ordinary differential equations in engineering
Zapoměl, Jakub ; Šremr, Jiří (referee) ; Opluštil, Zdeněk (advisor)
This bachelor thesis deals with the determination of the shape of the deflection line for boundary value problems in strength of materials. There are several methods for solving boundary value problems. This thesis focuses on the Green's function method. It provides a basic review of the properties of ordinary differential equations, an introduction to the Green's function method and the actual application of the findings to beam bending models. The concrete models are solved using an interactive program developed in Matlab software.

Sturm-Liouville problem in vibration of continuous systems
Varmusová, Alanis ; Nechvátal, Luděk (referee) ; Šremr, Jiří (advisor)
The goal of this thesis is to compile the theory concerning the Sturm-Liouville problem and partial diferential equations of the second order. Based on the findings the necessary eigenvalues, eigenfunctions and Green's functions, which are connected with the Sturm-Liouville problem, are derived in the thesis. Results of derivation are used in the solution of the initial-boundary value problem for wave equation, which results are then interpreted graphically.

Influence of velocity model uncertainty in earthquake source inversions

Title: Influence of velocity model uncertainty in earthquake source inversions Author: Miroslav Halló Department: Department of Geophysics Supervisor: doc. RNDr. František Gallovič, Ph.D., Department of Geophysics Abstract: Earthquake ground motions originate from rupture processes on faults in Earth. Constraints on earthquake source models are important for better un- derstanding of earthquake physics and for assessment of seismic hazard. The source models are inferred from observed waveforms by inverse modeling, which is subject to uncertainty. For large tectonic earthquakes the major source of un- certainty is an imprecise knowledge of crustal velocity model. The research topic of this Thesis is the influence of the velocity model uncertainty on the inferred source models. We perform Monte-Carlo simulations of Green's functions (GFs) in randomly perturbed velocity models to reveal the effects of the imprecise veloc- ity model on the synthetic waveforms. Based on the knowledge gained, we derive closed-form formulas for approximate covariance functions to obtain fast and effective characterization of the GFs' uncertainty. We demonstrate that approxi- mate covariances capture correctly the GF variability as obtained by the Monte- Carlo simulations. The proposed approximate covariance functions are...
