Labour migration from Serbia to the Czech Republic.
Kovar, Leona ; Kocián, Jiří (advisor) ; Roginer Hofmeister, Karin (referee)
The thesis deals with the current labour migration from the Republic of Serbia to the Czech Republic. The aim of the thesis is to answer three basic questions: What are the push factors for labour migrants from Serbia to emigrate to the Czech Republic? What are the pull factors for labour migrants from Serbia to move to the Czech Republic? Do migration networks play a role in the moving of labour migrants from Serbia to the Czech Republic, and if so, what role is that? To achieve the answers, a qualitative analysis of 27 ethnographic interviews with labour migrants from Serbia, living in the Czech Republic, is used, along with an analysis of migration theories, concepts, and phenomena. The first part of the thesis is devoted to the methodological approach and analysis of available literature. The second part presents relevant migration theories (push-pull theory, migration network theory, neoclassical economic theory, new economic approaches, globalization theory, and transnationalization theory), concepts (gastarbeiter and diaspora), phenomena (brain drain), and terms used in the work. The third part of the thesis provides an analysis of certain aspects of immigration policy and immigration trends in the Czech Republic, as well as migration trends from Serbia to the Czech Republic.

Development and implementation of 3D geometry extraction method for topological optimization
Šotola, M. ; Rybanský, D. ; Maršálek, P. ; Halama, R. ; Kopačka, Ján ; Ježek, Ondřej ; Gabriel, Dušan ; Tejc, J. ; Pašek, M. ; Kovář, L.
This research report TN01000024/08-V012 is an output of the subtask of the project TN1000024/08 Automation and production system optimization, one of the objectives of which is to develop methods of post-processing of topological optimization (TO) results in cooperation with MECAS ESI Ltd. Three different smoothing approaches are discussed: the Taubin method, volume representation using radial basis functions and smoothing by remeshing using the Netgen library.

Review of methods for the post-processing of topological optimization results
Kopačka, Ján ; Ježek, Ondřej ; Gabriel, Dušan ; Šotola, Martin ; Rybanský, David ; Maršálek, Pavel ; Halama, R. ; Tejc, J. ; Pašek, M. ; Kovář, L.
The research report is an output of the sub-project TN1000024/08: Automation and production system optimization in cooperation with MECAS ESI Ltd on the development of methods for post-processing of topological optimization (TO) results. In this report a detailed survey of these methods is introduced as necessary tool for seamless integration of the results TO with subsequent numerical simulations and additive manufacturing. The selected method for post-processing based on a level-set approach using radial basis functions has been implemented and successfully tested on a well-known 2D Messerschmitt-Bölkow-Blohm (MBB) beam test problem.

Introducing the area of polygons, particularly by method of releasing parameter in primary schools
Kovář, Luděk ; Kloboučková, Jaroslava (advisor) ; Tůmová, Veronika (referee)
This thesis deals with the description of constructive approach to teaching mathematics in the third grade of primary school. Teaching mathematics is focused on geometry, specifically on one way of introducing the area of the scalene triangle which describes the relation between a side and its height and corresponding area. In the thesis I describe six particular lessons, their preparation, process of their realization and my own reflections. In these lessons, I analyse some cognitive phenomena as well as social relationships among pupils. Furthermore, I present a detailed examination of tasks from the final diagnostic test, in which I aim towards proving success of this method of teaching mathematics. After four years, I attempt to verify the permanency of the knowledge pupils gained in these particular lessons. I illustrate this by presenting analysis of additional exercises. The whole experimental process was led within the method of releasing parameter. Individual lessons were in accordance with given stages of this method, as described in specialised literature. I verified that the above mentioned method is applicable in teaching mathematics even in the third grade of the primary school. KEYWORDS teachingstyles, perimeter and area, square grid, polygon, method of releasing parameter

Immunogenic cancer cell death triggered by free and polymer bound doxorubicin
Kabešová, Martina ; Kovář, Lubomír (advisor) ; Anděra, Ladislav (referee)
Immunogenic cancer cell death triggered by free and polymer-bound doxorubicin Water-soluble polymeric drug carriers based on N-(2-hydroxypropyl) methacrylamide (HPMA) have been developed to avoid undesirable side-effects of systemically active cytostatic drugs. Conjugates based on HPMA copolymer passively accumulate in tumor tissue of solid tumors due to the effect of enhanced vascular permeability and retention effect (EPR effect). Active accumulation can be achieved by binding of targeting structure recognising tumor-specific receptors to the polymeric carrier. Conjugation of free doxorubicin to HPMA polymeric carrier significantly reduces its nonspecific side effects in vivo by maintaining effective antitumor activity in vitro and in vivo. Besides direct cytotoxic effect on tumor cells, HPMA conjugates with bound doxorubicin possess immunostimulatory properties and induce long-lasting anti-tumor immunity in cured mice. Recent studies have shown that free doxorubicin induce immunogenic apoptosis in tumor cells. Those cells are dying by cell death which possesses characteristic markers of apoptosis but these cells are able to activate the immune system and thus induce effective anti-tumor immune response. This phenomenon has been described as crucial for a development of treatment-induced...

DAQ application development for measurement of electric energy consumption in machinery
Kovář, Lukáš ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
The goal of the diploma thesis is to develop application for data acquisition and analysis during the measurement of electrical consumption at mechanical machines. First part of the diploma thesis is providing general summary about the methods of measuring the electrical consumption. Special focus is given on methods of the metering electrical consumption in three-phase distribution network. Furthermore, the data acquisition components are being described. Hardware components and development environment LabVIEW where the program itself was created are detailly described.
