Software tool for education of the computed tomography
Doležalová, Anna ; Králík, Martin (referee) ; Mézl, Martin (advisor)
This semestral thesis is focusing on the process of displaying X-ray scanning and it’s simulation. There is described X-ray radiation and it’s possible interactions and changes. It’s also focused on the origin and detection of this radiation. In the practical part of the thesis, there is simulated the origin and attenuation of spectrum while comming through material. Then simulation software is created using MATLAB program. The simulation software allows to simulate basic processes of classical systems: X-ray tube, the interaction of radiation with the patient and subsequent detection. After selecting parametrs of simulation, the effects of the selected parametrs and X-ray spectrum will be displayed. The thesis also describes and subsequently simulates how image reconstruction of computed tomography works.

Volumes of unit balls of Lorentz spaces
Doležalová, Anna ; Vybíral, Jan (advisor) ; Lang, Jan (referee)
This thesis studies the volume of the unit ball of finite-dimensional Lorentz sequence spaces p,q n . Lorentz spaces are a generalisation of Lebesgue spaces with a quasinorm described by two parameters 0 < p, q ≤ ∞. The volume of the unit ball Bp,q n of a general finite-dimensional Lorentz space was so far an unknown quantity, even though for the Lebesgue spaces it has been well-known for many years. We present the explicit formula for Vol(Bp,∞ n ) and Vol(Bp,1 n ). We also describe the asymptotic behaviour of the n-th root of Vol(Bp,q n ) with respect to the dimension n and show that [Vol(Bp,q n )]1/n ≈ n−1/p for all 0 < p < ∞, 0 < q ≤ ∞. Furthermore, we study the ratio of Vol(Bp,∞ n ) and Vol(Bp n). We conclude by examining the decay of entropy numbers of embeddings of the Lorentz spaces.

Big families of incomparable continua
Doležalová, Anna ; Vejnar, Benjamin (advisor) ; Kurka, Ondřej (referee)
The goal of the thesis is to define the basic concepts of continuum theory and explore properties of some special continuous mappings between them. These are used for the construction of infinite families of continua which are incomparable by homeomorphic, open or monotone mappings. Special concern is given to families of dendrites. In particular, we describe an uncountable family of homeomorphically incomparable dendrites, an uncountable family of open incomparable dendrites and a countable family of monotone incomparable local dendrites. Existence of an uncountable family of monotone incomparable dendrites is open problem, in this thesis we describe a family of such dendrites of arbitrary finite cardinality.

Production Networks of Automobile Industry as a Factor of Regional Development in Czechia
Doležalová, Anna ; Pavlínek, Petr (advisor) ; Kopačka, Ludvík (referee)
Production Networks of Automobile Industry as a Factor of Regional Development in Czechia Abstract Thesis "Production Networks of automotive industry as a factor of regional development in Czechia" deals with linking economic globalization, global production networks and regional development. The main purpose is to analyze the relationship between regional development and the Czech automotive industry, depending on the position of automotive firms in global production networks. The work focuses on three areas: quantitative analysis of the automobile supplier sector, the spatial heterogenity of firms located in different positions in global production networks and formulating typology of regional development potential. The methodology employs 37 indicators for inter-regional comparisons. Based on comparative analysis, I identified a typology of regions according to their regional develompent potential. Keywords: automotive industry, global production networks, regional development

F. A. Stelzig a počátky politické aritmetiky u nás
Doležalová, Anna ; Závodský, Prokop (advisor) ; Kačerová, Eva (referee)
Tato diplomová práce se zabývá vývojem politické aritmetiky, a to už od jejích prvopočátků ve světě. Primárně si však klade za cíl nastínit vývoj této statisticko-demografické discipliny v českých zemích, s důrazem na dílo pražského úředního lékaře F.A.Stelziga. Podklady pro tuto práci jsem čerpala částečně z novodobých prací zabývajících se touto tématikou a částečně z originálních statí politických aritmetiků 19. století (viz seznam pramenů a literatury).
