Serial Data concentrator in VHDL
Řeháček, Tomáš ; Valach, Soběslav (referee) ; Burian, František (advisor)
In the bachelor’s thesis text there are summarized basics of VHDL language, ISE Webpack development environment is described. Also the way of communication and properties of serial unit are described as well as Ethernet standard properties and the way of communication via MII interface. Hardware used for the data concentrator design is briefly introduced in the next part. At the end of the thesis there is analysis of the data concentrator design for data transmission from serial unit to Ethernet using protocols UDP/IP.

Universal ethernet module
Řeháček, Tomáš ; Valach, Soběslav (referee) ; Burian, František (advisor)
This master’s thesis deals with creating a universal module with Ethernet interface and its using for digital values measurement. The main module components are gate array FPGA, microprocessor, PHY chip and RJ45 connector. Printed circuit board is in this thesis designed in Eagle. The chase for board is drawn in SketchUp and printed on a 3D printer. There is a code implemented in created universal module that is performing the function of logic analyzer. Data measured by the analyzer are sent to the Ethernet using UDP/IPv4 protocol. The last part is creating an application in C# to display the measured waveforms on a PC.

The First Apostolic Nuncio in Prague Clemente Micara and his Reflection in the Contemporary Czech Press in the Years 1920-1923
Řeháček, Tomáš ; Šmíd, Marek (advisor) ; Petráček, Tomáš (referee)
In the newly formed Czechoslovak Republic, the Catholic Church lost the position it had in the Austro-Hungarian monarchy. It was necessary to change almost the entire Church structure, replace the majority of the bishopric, establish new church schools and find a new way of coexistence of church and state. A papal nunciature was established in Prague and an embassy of the Czechoslovak Republic was established in Rome. The first Vatican nuncio, Clemente Micara, was sent to Prague, where he worked there for less than four years. His task was to carry out the necessary changes pro- posed by the Vatican to strengthen the position of the Catholic Church in Czechoslovakia, and his mission was successful.

The Effectivity Analysis of BI using Oracle database
Řeháček, Tomáš ; Pour, Jan (advisor) ; Kovář, Štěpán (referee)
The main goal of this diploma thesis is to provide advice and recommendations to increase the effectiveness of Business Intelligence using Oracle database. More specifically, the focus of the thesis is the optimization of ETL processes and objects in a data warehouse. Tests to compare different optimization techniques are performed to meet the defined goal. These tests are based on common tasks solved in data warehouses on daily basis. Tests are also supported by publications of leading authors in Oracle environment. The second goal of this work is the implementation of appropriate optimization techniques to real ETL pro-cess in order to increase its effectiveness. Performance changes are compared and measured using metrics defined for the ETL process and requirements from client. Optimization techniques presented for main objectives are used to achieve the second objective. Contri-bution of the thesis is to show the most important optimization techniques and tips that every developer should know and be able to use effectively. Another added value is au-thor's practical experiences in real data warehouse environment.

Impact of partitioning on the performance of Oracle database
Řeháček, Tomáš ; Macák, Petr (advisor) ; Palovská, Helena (referee)
The main aim of this bachelor thesis is to provide information about how to use partitioning in an Oracle database and to determine its effect on change in performance during database load. Description of this additional functionality and proposal appropriate testing environment in which it is possible to make measurements were necessary in order to achieve the main goal. The contribution is in the recommendations that can be drawn on the basis of the values obtained during tests performed. The thesis examines general options of partitioning, benefits and costs that are associated with its use, application partitioning methods and management capabilities. Tests are conducted on a large number of scenarios in the practical part. Conclusions, recommendation and suitable conditions for use of partitioning are based on tests.
