Automatic train protections system tester
Marek, Michal ; Musil, Vladislav (referee) ; Šteffan, Pavel (advisor)
The Master´s thesis describes continuous automatic train protection system and its functional properties, principally the transmission of special encoded signal between stationary part and rail vehicle. There is also summarized some important information about the gear rotational speed sensors and its communication with other onboard peripherals. Depends by analysed parameters of electrical signals, the general suggestion of portable electronic device is outlined. Portable electronic device or TESTER will be used to in phase of testing mobile part of automatic train protection system mounted onboard of rail vehicle. Tester will generate equivalent electrical signals to signals in system automatic train protection and the real system response will be possible to evaluate. The generator block allows to model real electrical signals in automatic train protection technology type LS or type EVM and signals rail vehicle odometry.

Proposal for a revitalization of greenery in the selected area
MAREK, Michal
In this diploma thesis is being solved a castle garden in Český Krumlov. It's current state and historical development is summarized. The garden was founded by Jan Kristián from Eggenberg in 17. century. The garden has gone through significant changes over the years. Those changes can be seen from attached plans. At first baroque garden become mostly romantic one. The biggest change is placement of revolving auditorium though. Before the auditorium was built, beautiful flower beds ware on this spot. Those beds ware the pride of the garden. Most of this work is focused on current state of the garden. From summarized current state and discussed gardens in Kroměříž and Lednice is obvious, that current state of the garden is very neglected and the garden needs regeneration.

Automatické čištění HTML dokumentů
Marek, Michal ; Straňák, Pavel (referee) ; Pecina, Pavel (advisor)
This paper describes a system for automatic cleaning of HTML documents, which was used in the participation of the Charles University in CLEANEVAL 2007. CLEANEVAL is a shared task and competitive evaluation of automatic systems for cleaning arbitrary web pages with the goal of preparing web data for use as a corpus in the area of computational linguistics and natural language processing. We try to solve this task as a sequence-labeling problem and our experimental system is based on Conditional Random Fields exploiting a set of features extracted from textual content and HTML structure of analyzed web pages for each block of text.

Led matrix 8x64
Marek, Michal ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
The bachelor thesis describes what is a LED matrix and how to control them. The function of the control circuits for the LED matrixes, the function of the current controller and microcontroller programming method are delineates in the project. These include microcontroller programming via universal serial bus, changing source code parameters via local ethernet network with the ethernet connect module, using standard peripheral buses for serial transmissions and the ways of controlling LEDs using relevant libraries. Objective is to introduce a solution for LED controlling using the Windows software application and propose complex assembly includes all the necessary blocks, which provides simple operating for new users.

The Complex Diagnostics of Reinforced Concrete Construction
Marek, Michal ; Heřmánková,, Věra (referee) ; Anton, Ondřej (advisor)
The aim of this thesis is a complex evaluation of reinforcement in reinforced concrete construction and its comparation with contract documents. In the next step we will calculate static reviews for each part of the construction. In case that some of the parts will fail this review, we will have to project such a solution that the construction wont get damaged from excessive load. In the end we will make an all in all evaluation of the examination and the construction.

Datalogger for UL aircraft
Marek, Michal ; Vágner, Martin (referee) ; Klusáček, Stanislav (advisor)
This thesis describes the design of flight data recorder for UL aircraft. The theoretical part describes the basic principles of measurement of the quantities in relation to the operation of the aircraft, such as altitude, air speed. A separate chapter deals with systems for determining of GPS position. Furthermore, there are examples of instruments measuring these quantities. The practical part is focused on the description of selected components and their connection to PIC24FJ64GA004 microcontroller. This is followed by a description of the control of USB drives with USB Controller Vinculum-II. The work is finished by the functional test of the device.

Leaf area index development and radiation use efficiency of a poplar short rotation coppice culture
Tripathi, Abishek ; Fischer, Milan ; Trnka, Miroslav ; Orság, Matěj ; Vanbeveren, S. ; Marek, Michal V.
Leaf area index (LAI) is the most appropriate parameter for analyzing canopy structure and crop productivity. LAI and radiation use efficiency (RUE) were estimated to evaluate the productivity of a short rotation coppice culture of a poplar clone. RUE was calculated as the ratio between total aboveground woody biomass and available photosynthetic active radiation (PAR) accumulated during one growing season. Prior to coppicing, LAI reached a maximum value of 7.3 (in 2009), whereas the maximum LAI after coppicing was 6.8 (in 2012). The maximum RUE reached prior to coppicing was 0.25 g mol−1 (in 2009), while after coppicing it was 0.20 g mol−1 (in 2012), which did not represent a significant difference (p > 0.05).

Financial analysis of PETROF, spol. s r.o.
Marek, Michal ; Čámská, Dagmar (advisor) ; Krause, Josef (referee)
The goal of this bachelor's thesis is to analyse financial health and stability of PETROF, spol. s r.o., by using methods of financial analysis. This company is well known manufacturer of pianos not only in the Czech Republic, but all across the Europe. As a data source were used data officially published by the company from years 2009 to 2013. The tools chosen for this bachelor's thesis are explained in the theoretical part, then, in the practical part, they are applied to analysed company with enclosed commentaries and some of them are measured against competitors.
