I/O Peripheries for Modbus/TCP server
Mikula, Matej ; Štohl, Radek (referee) ; Macho, Tomáš (advisor)
The thesis focuses on the development of input-output peripherals for a Modbus TCP server. Its goal is to create a functional model of a device with analog and digital inputs and outputs. The device is capable of communicating with the PLC Allen-Bradley Logix series. It can report the state of its inputs, and it is possible to set the value of its outputs. The functionality of the proposed device is verified by creating a simple application for the PLC.

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Experimental methodology of measuring
Lojková, Lea ; Hejtmánek, Petr (referee) ; Havlíková, Marie (advisor)
This work is focused on the development of a thorough study about ISO standards focused on the vehicle dynamics, standardized tests of vehicle dynamics and measured variables that allow us to describe and model the behaviour of riding vehicles properly. In the Appendix A of the thesis, there is a list of all known ISO standards dealing with given topic. The standard ISO 15037-1 Road vehicles – Vehicle dynamics test methods, Part 1: General conditions for passenger cars is described in detail, including the forms for test reports and the Appendix C and D. In the thesis, there is also described a model of minimal needed measuring system that is still in good accordance with the standard ISO 15037-1 and fulfills all its requirements. Detailed description of all used sensors that are used to measure required variables is given, as well as a short description of all sensors that are used for measurement of other variables. After that, measurement abilities of the instrumentation of measuring system RIO used in ÚADI FSI Brno is compared and confronted with requirements given by the standard, to see, if all given criteria are properly fulfilled. Because of the fact that standard-given criteria are quite mild, while the equipment of the faculty is high-level technology, mostly made directly for measuring of dynamic parameters of the vehicles, including racing vehicles, the system is in full accordance with the standard ISO 15037-1.

Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.

Manual pumps
Matis, Michal ; Šedivý, Dominik (referee) ; Štigler, Jaroslav (advisor)
This thesis describes manual pumps. It contains research about history of usage of these pumps, further it deals with some pumps used today (construction, materials, pros-cons). Also it is pointing out on pumps in developing countries, which are used in places with lack of drinking water. In practical part is described design procedure of pedal-powered pump.

Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.

Remote control of targets
Tkáč, Stanislav ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The task of this work is to make a functional device, that is intended to close only one of several (38 to 55) of electromagnetic valves. Which valve is going to be switched is elected either of the push-button keypad, or from a PC via RS 232. Equipment must be made using one or more PIC processors.

Power control of combustion engines
Slavík, Tomáš ; Beran, Martin (referee) ; Zháňal, Lubor (advisor)
The main subject of this dissertation is a comparison between different methods of controlling the output in compression and spark ignition engines in light of economic- ecological parameters, effects on engine functioning as well as vibrations. Main types of power control, their principle, advantages and disadvantages are presented in the text. There are several comparative simulations described and presented at the end of this work that were created by using a multi-body system. Calculation of parameters and simulations were selected to approximate resulting values to real values as much as possible.

Suggestion for the Improvement of the Company´s Culture
Jelínek, Tomáš ; Krejčíř, Petr (referee) ; Pokorný, Jiří (advisor)
The diploma work is worked on the subject of improvement upon the firm culture. The theoretical pieces of knowledge realize detailed investigation of firm culture problems. The diploma work includes collection of single theoretical informations and empirical experience with their resulting exploitation in the practical part. The proposal part should be an economie contribution to the firm TATSUNO-BENČ EUROPE a.s. after its application in the practice.
