Design of core shooting machine with a fixed head
Vacek, Lukáš ; Pavlík, Jan (referee) ; Bradáč, František (advisor)
This work deals with shooting machines with fixed head engineering design. The first part follows up purpose of cores using in the foundry industry and its development. Marginally addresses problems arising in the foundry industry related to the environment and then comparing shooting machines used for the cores production. The work includes a three-dimensional structural model of shooting machine describing the various parts, strength calculations and detailed design of machine worktable.

Sound installation
Vacek, Lukáš ; Frank, Jakub (referee) ; Ambrůz, Jan (advisor)
In my bachelor thesis, I tried to evaluate my experience with working with sound, vibrations and the way they spread through different types of material. Examine the characteristics of the material and its properties through a minimalist form and through a targeted reduction of the vibrations themselves, while observing how they affect human perception. The fundamental concept of the installation is derived from this relationship. I am fascinated by how vibration and sound in space can create a situation that engulfs the viewer. The significance and the symbolism of this correlation, i.e. the ability of sound to create, distort and transform space and the way humans perceive this action is the main concept of my bachelor thesis. The vibrations represent the constant movement, change and uncertainty that are key aspects of this installation, but also of human existence and its perception. The scenographic nature of the artwork illustrates and alters the space around it with its audiovisual features, giving the impression of its own imaginary architecture. This creates a dynamic dialogue between the objects, which mutually vibrate and resonate through connections between the space and the audience.

Adventure Game with Intelligent Cooperating Actors
Vacek, Lukáš ; Samek, Jan (referee) ; Zbořil, František (advisor)
The goal of this master's thesis is to design and implement framework that can be used for development of agent systems. Framework is implemented in Java and encapsulates JADE library. Framework is used for implementation of adventure game. There are several characters (agents) with specific roles who cooperate and try to achieve their goals.

A Tool for Automated Testing of GUI
Vacek, Lukáš ; Charvát, Lukáš (referee) ; Smrčka, Aleš (advisor)
Despite of GUI usability and availability is GUI testing quite new specialization technique. Manual testing is often used for verifying of GUI functionality. The aim of this work is to create a tool for testing and controling GUI. By tool is meant library for automated testing of GUI using object recognization method. Library detects basic GUI elements and controls them according to their standard behavior. Object detection depends on image processing and tracing graphic changes while mouse and key events are incoming.

Ma Zhiyuan - Huangliangmeng (analysis and translation)
Vacek, Lukáš ; Lomová, Olga (advisor) ; Andrš, Dušan (referee)
V této práci se budu zabývat čínským dramatikem z přelomu 13. a 14. století Ma Zhiyuanem (Jl; ft.iit.) a především jeho divadelní hrou Huangliang meng1 (~ :W:. ~). Pokusím se ukázat problematiku překladu čínského literárního útvaru a zjistit, zda se překladatelské teorie, které zde zastoupí práce a názory J. Levého, založené na zkušenosti z překládání literárních děl v rámci evropského kulturního kontextu, dají použít jako teoretické východisko i při překládání takto jazykově i kulturně odlišného útvaru. Mým záměrem je především podat ucelený pohled na problematiku a charakter hry Huangliang meng, zasadit ji do kontextu žánrových konvencí a doby, kdy vznikala, a ukázat, v čem spočívají její specifika. Na rozboru hry budu chtít ukázat zásadní problémy překladu a na několika příkladech se zároveň pokusím postihnout výrazné literární prostředky a autorský styl Ma Zhiyuana. Poté přistoupím k literárnímu překladu prvního jednání, abychom si jednotlivé přístupy, problémy a charakteristické motivy představili z celkového pohledu překladatele i čtenáře.

Field of values of a matrix: Theory and computation
Vacek, Lukáš ; Tichý, Petr (advisor) ; Tůma, Miroslav (referee)
The field of values of a matrix A is a convex set in the complex plane assigned to A. It is important in matrix analysis, especially in invetigation of properties of nonnormal matrices and matrix polynomials, in study of the con- vergence of iterative methods applied to these matrices, in the estimation of ma- trix function norms, etc. This thesis summarizes theory about the field of values of a matrix, formulates open problems and explaines the main idea of the basic numerical method for its computation. In numerical experiments the standart algorithmic realization of method is compared with alternative approaches that use power method, Lanczos algorithm and Chebfun.

Numerical solution of traffic flow models
Vacek, Lukáš ; Kučera, Václav (advisor)
Our work describes the simulation of traffic flows on networks. These are described by partial differential equations. For the numerical solution of our models, we use the discontinuous Galerkin method in space and a multistep method in time. This combination of the two methods on networks is unique and leads to a robust numerical scheme. We use several different approaches to model the traffic flow. Thus, our program must solve both scalar problems as well as systems of equations described by first and second order partial differential equations. The output of our programs is, among other things, the evolution of traffic density in time and 1D space. Since this is a physical quantity, we introduce limiters which keep the density in an admissible interval. Moreover, limiters prevent spurious oscillations in the numerical solution. All the above is performed on networks. Thus, we must deal with the situation at the junctions, which is not standard. The main task is to ensure that the law of conservation of the total amount of cars passing through the junction is still satisfied. This is achieved by modifying the numerical flux for junctions. The result of this work is the comparison of all the models, the demonstration of the benefits of the discontinuous Galerkin method and the influence of limiters.

Causal objections to a bill of exchange and a promissory note, their types and proceedings related to them
Vacek, Lukáš ; Patěk, Daniel (advisor) ; Čech, Petr (referee)
and keywords Causal objections to a bill of exchange and a promissory note, their types and proceedings related to them The subject of this thesis are causal objections to bill of exchange and promissory note, their types and proceedings related to them. The aim of the thesis is to provide a comprehensive overview of causal objections as a defense against produced bill of exchange (promissory note) based on an analysis of prosessional literature on the topic and the relevant case law. Thus, the thesis deals both with causal objections as substantive law institute and their practical application through procedural law institute of objections against bill of exchange (promissory note) payment order. The thesis consists of the preface, three chaptes and the conclusion. The first chapter deals with basic aspects of the term of "bill of exchange" (or the "promissory note"). The chapter is devided into four subchapters. The first subchapter analyses different definitions of the bill of exchange (promissory note) as they can be found in the professional literature and the case law and these definitons are compared to one another. The second subchapter deals with typical signs of bills of exchange (promissory notes) as a security. The essentials of such a security are described in the third subchapter. The...
