Laboratory tasks for ball on an inclined plane
Řezáč, Martin ; Graf, Miroslav (referee) ; Blaha, Petr (advisor)
The thesis deals with the identification and control of dynamic systems using LabVIEW graphical programming environment. Cascade form of control with PI and PD controllers has been used for regulation and designed in Matlab. These controllers were then tested on real product. Laboratory exercises with model solutions are also included.

Supporting algorithms for electrical motor control
Řezáč, Martin ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This thesis is focused on a creating supporting drivers and algorithms for electrical motor control using CPU TriCore TC275 CA. The first part is devoted to processor description and selected peripherals, which are A/D converter, a timer for creating the PWM signals and the second timer for processing singnals from encoder. All drivers are tested on an aplication kit, which is equipped with TC275 CA processor. The second part analyzes the measurement quality of GMR sensor TLE5009. Special testbench was prepared for sin cos data capturing and for their comparison with precise encoder position measurement. It was composed from DC motor having both sensor types on commons shaft. Data are acquired using LabView. Subsequently, it analyzes the sensor data, their compensation and subsequent comparison with measured data from the encoder.

Electronic Support for Renting Small Freetime Facilities
Řezáč, Michal ; Smrž,, Pavel (referee) ; Dydowicz, Petr (advisor)
This work deals with the analysis of commercial applications available for support accounting agendas, their attributes, and projecting a data and process model for the most simple but sufficient application. In the proposed solution is preferred simplicity and maximum availability solutions for the ordinary national sole trader or for a company which needs effectively use housing fund and it is not its main activity. For this reason, the application is made for normal software for PC and specifically for MS Office which was tested in real environment.

Optimization of data transit in network
Řezáč, Michal ; Škorpil, Vladislav (referee) ; Kubánková, Anna (advisor)
This bachelor thesis is divided into two parts. The first part deals with and describes necessary teorethical units, together with analyse of ISP network and other input informations. These findings are further used in second part of bachelor thesis. The practical part dealt with testing of optimization mechanisms in the laboratory network. Thereafter has been done a wider tests of optimization mechanisms based on different ways of marking data streams and deploying these rules. The advantages and comparision of these methods were further evaluated.

Honeypot for wireless communication protocols of IEEE 802.11 family
Řezáč, Michal ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
Objective of this master thesis solves possible way of WiFi Honeypot realisation, which is constructed to detecet malicious network activity and attacks in radio environment that uses a set of IEEE 802.11 protocols. A specific configuration was created on the mITX format motherboard and contains scripts and software for data collection, analysis and its evaluation. Based on information and knowledge about specific network attacks it is possible to identify data traffic leading to anomalies and detect possible network attack. The final device was tested in real use for long-term data collection and evaluation of network activity in the given location. This fulfills the main goal of this work, which is implementation of WiFi Honeypot with support for IEEE 802.11 protocols and with possible deployment for real use.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Systems of Transducers: Definition, Properties, and Applications
Řezáč, Michal ; Kövári, Adam (referee) ; Meduna, Alexandr (advisor)
Currently, finite and pushdown automata are used to describe programming language compilers as two separate parts. This thesis aims to define a system of transducers that allows to describe a compiler by one aggregate system, instead of two independent transducers. The system of transducers presented in this paper is based on finite and pushdown transducers. It is a simple model without internal communication. Because of this property, it is not suitable for compiler formalization but because of its simplicity, the system is easily extensible with new features and can thus serve as a basis for further research.

Information System Assessment and Proposal for ICT Modification
Řezáč, Michal ; Smrž,, Pavel (referee) ; Koch, Miloš (advisor)
This diploma work deals with the information system assessment and proposal for its modification. The theoretical part describes the basic concepts and issues related to information systems. The analytical part of assessing information system according to the methods for determining the current state. The design part is based on the analytical part and the main goal of this section is to design changes to improve the current situation with the subsequent economic evaluation.
