Public opinion on the role of a man as a teacher in kindergarten
KOUBA, Jan
The goal of this thesis is to find out what is the public opinion on man as teacher in kindergarten in South Bohemian Region by using a quantitative method. This bachelor thesis is divided into theoretical and practical part. The theoretical part contains the definition of kindergarten, a chapter about what teacher must know to work with kids, statistics of men in kindergarten in the Czech Republic and abroad, a summary of interviews with men who works as kindergarten teachers, thanks to MŠMT, and other researches on similar topics. The practical part includes research and its results, along with graphs.

Corrosion resistance of aluminum alloys
Kouba, Jan ; Pacal,, Bohumil (referee) ; Zmrzlý, Martin (advisor)
This diploma thesis deals with cerium-based conversion coatings for aluminium alloys. At first the mechanism of protection of metals by inhibitory substances is described in the theoretical section. The next chapter is devoted to application of lanthanide salts as cathodic corrosion inhibitors. Then the characterization of alloy AA 2024 follows. The main part is dedicated to the growth mechanism of the cerium-based mixed conversion coating on the alloy AA 2024. Finally, the factors affecting the character and the quality of obtained coatings are commented. In the experimental part an influence of the thermal activation together with the activation by a hydrogen peroxide was observed. The created film was characterized using SEM and EDS. The level of corrosion protection was evaluated by the polarization resistance measurement. erized using SEM and EDS. The level of corrosion protection was evaluated by the polarization resistance measurement.

Reactivity and controll of properties of metallic materials
Kouba, Jan ; Richtera, Lukáš (referee) ; Zmrzlý, Martin (advisor)
This study deals with properties of aluminum alloys that are used in aerospace industry, particularly with alloy 2024. In introduction, the fundamental questions of metallurgy of aluminum alloys and their basic properties are summarized. Then the specific parameters of alloy 2024 are commented. It is followed by short summary of aluminum inorganic chemistry and chemistry of its compounds. Next chapter is an introduction to corrosion and description of its particular forms. The following section sets out a summary of results of recent research in the field of aluminum alloys corrosion, some details about corrosion product analysis and published results concerning hypochlorites, what is the key substance in experimental part. The experimental part is focused on the influence of temperature and concentration of sodium hypochlorite solution on corrosion of Al 2024, cladded by pure aluminum.

Routing simulation in wireless networks
Kouba, Jan ; Kučera, Luděk (advisor) ; Peterka, Jiří (referee)
This work deals with creation of system for routing simulation in wireless networks. System allows the user to enter relevant parameters for simulation and analyses the network. System can assign simulation parameters automaticaly based on chosen algorithm. First it counts node output powers and second communication routes. It is easy to add new algorithms. System is focused on user friendliness and good extensionality. The objective was not to implement realistic model of real network, but to create system where could be new algorithms tested. There is described architecture of the system in the work, so one can continue with development.

Memory Representation for Model Checker of C/C++
Kouba, Jan ; Šerý, Ondřej (advisor) ; Kofroň, Jan (referee)
We describe the design and C++ implementation of the newly created memory module (MM) in this work. It will be used in the GIMPLE Model Checker, an explicit state model checker, to represent the memory of checked program. MM diers from other code model checkers in the fact, that it stores ordinary C++ objects fullling a given interface as values. This allows to store, e.g., value data together with its type, a symbolic value used in a symbolic execution or a predicate over a stored value used in predicate abstraction. MM uses delta saving, incremental hashing and incremental heap canonicalization to save the state, canonicalize the heap and compute the hash of the state eciently.

Repertoire of songs for one voice of Advent and Christmas period in manuscripts from the workshop of Jan Taborsky from Klokotska Hora
Žižková, Jitka ; Černý, Jaromír (advisor) ; Frei, Jan (referee) ; Kouba, Jan (referee)
The presented work dealing with the repertoire of sacred songs for one voice in handwritten hymnbooks of Jan Taborsky from Klokotska Hora tries to answer the question whether the fact that they come from one clerical workshop influenced considerably the composition of the repertoire of the Advent and Christmas section or not. The essay about the development of the Czech hymnology, oriented for a medieval and Renaissance sacred song, points out the state of research in this field, which is not quite optimal. Mainly the absence of published catalogues of melodies and critical editions of significant sources is still a big obstacle of the research, which should head farther than for covering of white gaps in the basic heuristics. Nevertheless we point out some works here which offer and enable certain comparisons regarding both studies in specialized periodicals and degree works or PhD thesis. We follow the Prague citizen, Renaissance educated person and the owner of a clerical workshop Jan Taborsky not only in the context of the times when he lived taking account of the complicated situation of connections and antagonisms among the Utraquists, New Utraquists and Fraternal Unity {Jednota bratska}, but also as a topic of studies of musicological or generally historical literature. A list and characteristics of...
