Inertial Navigation Unit
Dvořák, Jan ; Hubík,, Vladimír (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on the design and realisation of inertial navigation unit INS. The unit is capable to measure, store and send data to a PC in real-time for a later offline processing. The first part of the thesis introduces the reader with the basic principles of accelerometers, gyroscopes and MEMS sensors. An introduction to coordinate systems and measuring errors is also included. The second and third part of the thesis deals with the analysis of the solution and the implementation of the INS unit. The fourth part of the document is dedicated to the software for the INS unit. This thesis concludes with explanation how the gathered data are processed.

Use of secondary heat ventilation air in multifunctional building
Dvořák, Jan ; Adamovský, Radomír (advisor) ; Neuberger, Pavel (referee)
This work deals with the theme of heat recovery from waste air and moisture recovery in residential areas. In a brief introduction, introduces the reader to various aspects of the energy system of choice due to the location and method of application equipment for heat recovery. In the following chapters is described theoretically transfer heat exchanger and determination exchanger efficiency, along with the search components including the basic distribution of each kind secondary heat recovery coils. Part of the theory is evaluating the effectiveness of the use of heat recovery equipment. The second part is solved draft multipurpose building consisting of a concert hall and the administrative section of the building. According to the resulting requirements for air-conditioning equipment has been selected with the described type of heat exchanger. Follow economic evaluation facility and the conclusion. The attachment is plan with a description of the location of equipment in the building.

Detection of anomalies in network traffic using compression methods
Blažek, Libor ; Dvořák, Jan (referee) ; Blažek, Petr (advisor)
The objective of the thesis is to design a practical demonstration of the functionality of selected compression methods. The following chapters will discuss the attacks on terminals and mentioned some measures. The show will be processed using two methods development environment. The attacks will detect anomalies in the network and subsequently carried out at one of the sample data compression methods. Data will be collected as normal operation at the terminal station, and then in the attack.

PH controller for aquarium
Dvořák, Jan ; Fedra, Zbyněk (referee) ; Šebesta, Jiří (advisor)
This bachelor’s thesis deals with the system which is designed as a pH regulator for aquarium water. The first and second chapter are aims to the basic requirements and possibilities on controlling of the potential of hydrogen in water. Main methods of the pH measuring, its controlling and regulation are included. The third chapter presents a design of the pH regulator system. The practical and software solution of this project is presented in the fourth and fifth chapter. There are described in detail the main blocks of the pH regulator - amplifier, galvanic isolator and output power stage. The results of the testing and measuring of the designed subsystems are introduced in the last part of the work.
