Integration of Migrants into the Czech Society
Pokorný, Martin ; Havlík, Radomír (advisor) ; Kubišová, Zuzana (referee)
The aim of my diploma work is to study the subject of integration of foreigners into the Czech society. For that purpose I intend to use research questionnaires and to compare my results with results of other researches conducted by NGOs. Secondary aim is to map legal status of foreigners in the Czech Republic, historical reasons for migration and its development, and the composition of migrating population in Europe. Furthermore, I will focus on access to health and social insurance and to the health care system as well as on education and work opportunities which foreigners have in the Czech Republic.

Nowhere and Somewhere: Utopia, Dystopia and Their Relative Location
Pomahač, Ondřej ; Pokorný, Martin (advisor) ; Hrdlička, Josef (referee)
The work criticizes the dichotomy utopia - dystopia, especially the way the two are being defined as genres in some theoretical reflections representing that represent the main approaches to the theoretical concept of utopia and dystopia. The work also analyses sample literary texts traditionally labelled as utopias or dystopias. In the first part we review some definitions and present their shortcomings. Consequently, we reject the attempts to make general definitions as they fail to become reasonable basis for literary research. The texts being accounted for are the classical utopias and dystopias: Thomas More's Utopia, Tommaso Campanella's The City of the Sun, Francis Bacon's New Atlantis, Yevgeny Zamyatin's We, Aldous Huxley's Brave New World and George Orwell's 1984. The second part offers a comparative approach to the text analysis based on textual relationships and the assemblage of text (the rules for building the text structure). Apparently, such analysis spares the need to make general definitions of the terms and to look for the nature of utopia and dystopia.

Intermediality in Modern Literature
Michlová, Lucie ; Pokorný, Martin (advisor) ; Bílek, Petr (referee)
The thesis outlines one type of intermediality in literature, musical composition transformed into the structure of the modern novel. The theme is based on the philosophical and aesthetic ideas of the sovereign status of music within the other arts. The relationship between literature and music is described on the basis of this specific status. In the sphere of these various relations, attention is paid to the connection between musical composition and the composition of a novel (the manifestation of musical composition in a novel is named here as the musicality of literature). In the central part of the thesis there are demonstrated the possibilities of application of musical compositional devices in a novel through an analysis of three works (The Counterfeiters by André Gide, Point Counter Point by Aldous Huxley and Tonio Kröger by Thomas Mann). These musical compositional devices are: multiple melodic lines, musical cyclical forms and a leitmotif.

Laser spectroscopy of semiconductor quantum dots
Pokorný, Martin ; Trojánek, František (advisor) ; Kuldová, Karla (referee)
This work is focused on examining photoluminescent properties of InAs quantum dots (QDs) on GaAs substrate covered by GaAs1-xSbx strain reducing capping layer (SRL) prepared by Stranski-Krastanow method. We measured luminescence decay time of two samples with different concentration of Sb in this layer. We investigated the influence of temperature, intensity and wavelength of the excitation pulse on the luminescent decay time. We also compared the properties of the samples after excitation by 760 nm pulse and 850 nm pulse - the former one is energetically above the substrate band gap; in the second case we excited only the QDs and the wetting layer (WL). We consequently derived recombination and relaxation processes occurring inside InAs QDs and also the transport of charge carriers from the substrate and the WL into QDs. One part of this diploma thesis was to learn about the methods of measuring ultrafast photoluminescence and build the experimental set-up.

Three stories between East and West: "Virtuous young man", "Divine lover", "Sacrifice of a child"
Špicová, Zuzana ; Vojvodík, Josef (advisor) ; Pokorný, Martin (referee)
The thesis deals with the realization of three narratives -"Virtuous Young Man", "Divine Lover", and "Sacrifice of a Child"- in diverse literatures of East and West. Basic form, characters/(arche)types, and motifs and their possible variations depending on cultural, literary, and religious/mythological setting are presented for each plot. Using historical and comparative poetics, each plot is analysed from the first extant adaptations in European and non-European literatures to the modern ones. The thesis puts an emphasis on specification and configuration of particular motifs, variations depending on the religious-mythological context, and tension between the same and different, general pattern and specific realization, type and character.

Matematická analýza regularizovaného modelu viskoelastické nenewtonovské tekutiny
Šalom, Pavel ; Pokorný, Milan (advisor) ; Bulíček, Miroslav (referee)
In this thesis we provide an existence result for a regularized model of viscoelastic non- newtonian fluid. We consider incompressible fluid with shear rate dependent viscosity and with Cauchy stress tensor capable to describe stress relaxation. An elastic part of the Cauchy stress tensor is governed by Oldroyd-type differential equation. In particular, we are interested in fluids with strong shear thinning effect. We prove that if the viscosity function µ (D) is such that tensor µ (D) D is p-coercive, monotone and has (p − 1)-growth for p > 6 5 and some other additional assumptions are satisfied, then there exists a solution to the system of PDEs describing the flow in a bounded domain. The proof is not simple because the convective term is not integrable with a high power. The problem is solved using Lipschitz truncation method for evolution PDEs. 1

Regularity criteria for instationary incompressible Navier-Stokes equations
Axmann, Šimon ; Pokorný, Milan (advisor) ; Neustupa, Jiří (referee)
Title: Regularity criteria for instationary incompressible Navier-Stokes equations Author: Šimon Axmann Institute: Mathematical Institute of Charles University Supervisor: doc. Mgr. Milan Pokorný, Ph.D., Mathematical Institute of Charles University Abstract: In the present thesis we study the global conditional regularity of weak solutions to the Cauchy problem for instationary incompressible Navier-Stokes equations in three space dimensions. In the first section, we present an overview of known conditions implying the full regularity of the equations under conside- ration. For the sake of clarity, we expose only the regularity criteria on the scale of Lebesgue spaces, especially in terms of the velocity and its components, the gradient of the velocity and its components, the pressure and the vorticity. In the subsequent sections, we generalize four regularity criteria using two different techniques. We are able to replace one velocity component or its gradient, consi- dered in the known results, by a projection of the velocity into a general vector field. For the purpose of the second method, we also generalize the multiplicative Gagliardo-Nirenberg inequality.

Compressible fluid motion in time dependent domains
Sýkora, Petr ; Feireisl, Eduard (advisor) ; Pokorný, Milan (referee)
In this work we study the existence of weak solutions for compressible Navier-Stokes equations in unbounded time dependent domains. Using the methods introduced in Feireisl E. Dynamics of Viscous Compressible Fluids we extend the results of article Feireisl E. Neustupa J. Stebel J., Convergence of a Brinkman-type penalization for compressible fluid flows, which studies the flow with a "no-slip" boundary condition on bounded domains. Next, we extend results of article Feireisl E. Kreml O. Nečasová Š. Neustupa J. Stebel J., Weak solutions to the barotropic Navier- Stokes system with slip boundary conditions in time dependent domains, which studies flow with compete Navier boundary condition. Finally, we discuss solutions for rotating fluid system. In this case, there are new members in momentum equation, representing the Coriolis and centrifugal force, which cause problems.

The expressiveness of experience: a structural and phenomenological account of the Russian formalists' "aesthetic of estrangement"
Flack, Patrick ; Vojvodík, Josef (advisor) ; Kubíček, Tomáš (referee) ; Pokorný, Martin (referee)
In their seminal studies in literary theory and poetics, the Russian formalists (Šklovskij, Tynjanov, Jakobson, etc.) famously claim that aesthetic experience amounts to a self-valuable, concrete act of perception functionally induced and conditioned by the formal structure of a work of art or literature. This aesthetic principle, christened by Šklovskij as "estrangement" (ostranenie), played an instrumental role in the formalists' contribution to the establishment and development of literary theory as an autonomous scientific discipline. It has also regularly inspired other thinkers and provided the impetus for productive new insights on art or literature, a fact that seems to underline its acuity and relevance. At the same time however, the formalists' "strange" account of art and literature has been routinely disparaged for being altogether inadequate, philosophically flimsy and descriptively too narrow. Critics have pointed out that the formalists' assertions on the topic of perception rest but on a set of ad hoc psychological hypotheses and are overly determined by their specific scientific aims and modernist prejudices. Worse, the principle of estrangement has been credibly attacked for being semiotically naïve and for stripping art and literature of any "content" or meaning, to say nothing...
