New laboratory practices with bus control system Foxtrot
Matouš, Milan ; Kubec, Jindřich (referee) ; Bátora, Branislav (advisor)
The bachelors thesis deals with laboratory exercises based on wiring system created by Foxtrot Company Teco. In the first part, the work briefly introduces the reader with issues of dealing with intelligent systems for houses, properties, topology and last but not least history of such systems. The following chapter involves a characteristic information regarding the abovementioned Foxtrot system – namely composition, function and communication. In order to ensure that the laboratory exercises are feasible a construction of laboratory boards was carried out and. The next sections of the thesis involve process of construction of such laboratory boards, description of all used components and the entire budget. The laboratory exercises are created in the Mosaic software. How to initially set up the software and certain basic information regarding its properties is contained within another chapter. The uppermost parts of the thesis are two laboratory tasks. The first one solves a programming of blinds, heating, cooling and switching of wireless buttons RFox. The other laboratory task aims to create circuits for switching and dimming channels of RGB LED strips which are controlled via the website.

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.

Transient effect at the output of a continuous-time LTI second order system controlled pulse-width modulation
Petera, Martin ; Richter, Miloslav (referee) ; Jura, Pavel (advisor)
The aim of this thesis is to determine the size of overshoot produced at the output of a linear continuous second order system controlled by pulse width modulation depending on the period and duty cycle of the modulation and system parameters. This thesis contains analytic calculation of the size of overshoot produced at the output of the second order system with damping ratio > 0, except the damping ratio equals to 1 (i.e. both underdamped and damped system) depending on period and duty cycle of the modulation. This thesis also includes a comparison of partial analytic results to numerical simulation in Matlab program and also with measurement at second order system model.

S-BUS I/O modul as a periphery for PLC Saia
Vaško, Jiří ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
The subject of my bachelor’s thesis is a design of I/O module with digital inputs and digital relay outputs. This module is supposed to communicate with SAIA PCD controllers via SAIA S-Bus protocol. The primary purpose of the module is using as a component of intelligent building control system. The former part of the thesis contains S-Bus characteristics. The next passages are focused on a schematic design and a description of the implemented code in the microcontroller.

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.

Solution of transfer junction on the Konečného square in Brno after putting the line NSRLD into operation
Rosík, Jan ; Veselý, Josef (referee) ; Smělý, Martin (advisor)
My master‘s thesis is concerned with study of location of tram stop, part od North - South Railway Line Diameter, which is supposed to be in underground level below Konečného square, important transfer junction. According to this location find out the best place to situate pedestrian exits and elevators in nearby streets Nerudova, Kotlářská and Veveří. After building up the station, pedestrian transfers will be safer and time to get into the centre of Brno/ job for commuter people will be shortened. This master thesis also deals with enlargement of tram islands, repositioning of trolleybus stop from Kotlářská street, movement of pedestrians in area and optimization of traffic lines.

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.

Modern Trends in Facility Management
Šimon, Peter ; Veber, Jaromír (advisor) ; Kohut, Ivan (referee)
The Master's Thesis is generally about facility management -- its essence, individual services it consists of, and also about their integration when they are provided by one key supplier, and finally about their complex integration in one service package, i. e. complex integrated supporting services provision what is a modern trend of this discipline. The aim of the thesis is to evaluate the advantages and efficiency of the trend of service integration under one key supplier based on specific practical examples.

Data envelopment analysis and their application in chosen branch
BANDÍK, Tomáš
Data envelopment analysis is one of methods how to compare the efficiency of transformation of the inputs to the outputs among production units. It helps to improve the efficiency and to identify weak points in production systems. The target of DEA is to divide focused subjects to efficiency and non-efficiency groups, comparing the amount of used sources as inputs and the amount of outputs. At first there are described some important conceptions in theory part. Then explanation of principes DEA follow and basic models analysis description too. The desription supposes constant returns to scale and variable returns to scale. There is contain a chapter devoting to description of using software. The practical part of my bachelor thesis is focused on using DEA to compare different countries by HDI ( human developmet index) The solution of this case work with characteristics used by calculating HDI.
