Framework design for automated testing of web sites
Sieber, Lukáš ; Šteffan, Pavel (referee) ; Frk, Martin (advisor)
This master's thesis is based on automated web applications testing with freeware instrument utilization developed under Google code project. It is called Selenium webdriver and become very popular during last years. Selenium webdriver is frequently used for web pages automation. Indisputable advantages of this solution are low entry cost, selenium is broadly used and also live community around that instrument with many useful informations. Main goal of this thesis is creation of automation framework created by Java programming language. This final framework will integrate Selenium webdriver and guarantee easy creation of testing scenarios. Because of this goal is placed mainly on separation of web page programmatic description and description of testing scenario.

Design and properties of low-frequency amplifier with vacuum valves
Piroha, Ladislav ; Musil, Vladislav (referee) ; Šandera, Josef (advisor)
The purpose of the bachelor’s thesis is explanation of theory and construction of low frequency tube audio amplifier with UV meter. Main focus is on history and development of vacuum circuits from its early beginning, on electrical parameters and applied physical principles. Explanation of operating characteristics of amplifier classes and comparison of vacuum tube sound acoustic performance against transistor amplifier one. Finally, there is build description of single ended amplifier class A.

Geographic information systems
Bílek, Ondřej ; Říha, Kamil (referee) ; Uchytil, Stanislav (advisor)
This diploma thesis focuses on the problematic of geographical information systems, analysis of the commercial as well as freeware software tools for GIS, analysis of vector and raster representation of geographical data and basic methods for data representation in GIS. The another important part of this thesis is the design of web application, that can be used as a tool for visualization of bussiness data from commercial company, in compare with data owned by Czech Statistical Office. This aplication is built on free platform Google Maps API V3.

3D Spatial Indexing of Objects
Drbal, Miroslav ; Dvořák, Radim (referee) ; Orság, Filip (advisor)
This diploma thesis defines the term indexing and in preamble are discussed known indexing algorithms and difference between indexing static and moving objects. The practical part of this diploma thesis is aimed to designing and implementing of indexing algorithm for open source application MaNGOS with respect to generic design pattern and effectiveness of spatial search queries for selection of the objects given properties in the specified area. At the end I present and discuss reached results.

Automatic Testing of JavaScript Restrictor Project
Bednář, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.

Synchronization of Generator by Applied Synchro-check Relay in Feeder Terminal
Gregr, Tomáš ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The aim of this work is a theoretical analysis of the parallel operation problems of electrical networks, as well as of the connecting the synchronous alternators to the electric power system. The knowledge of the present methods of connecting the synchronous alternators to the common network, of the historical evolution of this set of problems, of the phase conditions, their permitted deviations, as well as of the actual use of the modern phase automatic equipment, thereafter we to concentrate exclusively on the function of the synchro-check feeder terminal REF 543 produced by the ABB company. A part of this work is the analysis of the transient phenomena, that of accurate phasing, as well as that of phasing during a voltage, frequency and phase shift. Thereafter our goal is to get acquainted with the configuration program CAP 505, to carry out the communication of the REF 543 with PC, creating a new project, its configurating and then transmitting it to the REF 543 terminal. Further we occupy ourselves with the project to adjust the synchronous function synchro-check to phasing. The main task of this work is the proposal and the following testing of the connexion with the aim to test the synchronous function of the REF 543 terminal in cooperation with the output circuit breaker simulated on the test panel from the ABB company. Using the 6-phase generator from the UNIMA-KS company, this will simulate the voltage of the alternator. The network voltage is induced by means of the three-phase autotransformer from the Křižík n.p. company. We end this work up with a detailed description of connecting the terminal to the computer, with its following configuration, with setting up the required values, as well as with connecting the apparatus on order to test the conditions for the correct connection of the whole device.

Říčany u Brna - Residential Zone Design
Hojný, David ; Klepáček, Josef (referee) ; Radimský, Michal (advisor)
The subject of this work is a variant solution in residential areas. In the first case, the emphasis on the economic aspect with regard to the occupation of the building plots in relation to local roads. In the second study, the greatest weight is given to aesthetics and architectural design. The third situation is conceived as a compromise between reasonable price and architectural design. In all cases, a study situational architectural drawings. According to the multi-criteria analysis was GRID option is selected as the most suitable and also for the calculation is carried parking and parking places, vertical solutions and a distinctive cross sections.
