Paralelní víceúrovňové algebraické předpodmiňovače

This thesis studies multilevel preconditioners. In the introduction, we cover the theory of multigrid methods. We then connect two interesting topics (BPX additive multigrid and smoothed aggregation method) into a new multigrid approach. We will present a BPX preconditioner in t...

Tuhost a Hamiltonovskost grafů

The present thesis is motivated by the study of Chvátal's t_0-tough conjecture. We recall this conjecture in the context of Hamiltonian Graph Theory. We review partial results to the conjecture, and we analyse constructions which provide lower bounds to this conjecture and to s...

Numerická schémata pro rovnice vazkého stlačitelného proudění: Analýza a geometrie

The dissertation thesis presents a commented collection of research articles with results in the analysis of numerical schemes for systems that model viscous compressible fluids. They are mainly based on a pioneering work of Karper, who proved a convergence of a numerical scheme to...

Caggio, Matteo
Navier- Stokesovy rovnice a související problémy

The present thesis is devoted to the study of mathematical problems related to the Navier-Stokes equations in the context of mathematical rigorous derivation of models and their analysis. In particular we deal with the problem of singular limits in fl uid mechanics for compressible...

Jirásek, Pavel
Podmínky kompaktnosti ve variačních metodách

This dissertation studies variational methods and compactness conditions used in them. The methods are illustrated on the boundary problems for elliptic equations.

Prošková, Jitka
Aplikace duálních kvaternionů na vybrané problémy

In recent years, the study of quaternions has become an active research area of applied geometry, mainly due to an elegant and efficient possibility to represent using them rotations in three dimensional space. Thanks to their distinguished properties, quaternions are often used i...

Volek, Jonáš
Parciální dynamické rovnice na diskrétních prostorových oblastech

The dissertation thesis presents our recent results about the partial dynamic equations on discrete spatial domains (so-called lattices). These problems arise from the modeling of processes on spatially structured environment (e.g., cells, crystal lattices, electronic images). Consequently, we study p...

Chromatická teorie grafů

The goal of this thesis is to analyze several distinct problems regarding graph colorings. To motivate the topic, we first demonstrate that the theory of graph coloring provides useful tools for modeling a wide variety of scheduling and assignment problems. We then introduce basic&...

Rozvoj tvořivosti žáka v hodinách matematiky

This dissertation deals with the process of development of pupil's creative thinking, including analysis and comparison of pupils' problem-solving strategies. In the theoretical background, important terms are defined, i.e. mathematical concepts (relations, sets, binary relations, equivalence, groups an...

Steidl, Petr
Vysokoteplotní vrstvy Si-B-C-N a multifunkční vrstvy (Zr)-B-C-(N) připravené pulzním magnetronovým naprašováním

The first part of the thesis is focused on the detailed study of the microstructure and mechanical and optical properties of Si-B-C-N films prepared by reactive pulsed magnetron sputtering and consequently treated in air and inert gases up to 1700°C. The second part of t...

Mechanické a tribologické vlastnosti tenkých uhlíkových vrstev obsahujících vybrané kovy

Carbon coatings containing titanium and molybdenum were non-reactively sputtered in pure argon onto unheated Si substrate at a floating potential. A unbalanced magnetron was driven by DC power supply. The structure of the coatings was determined by X-ray diffraction. Ordering of the amo...
