Soldering station
Golian, Dominik ; Baštán, Ondřej (referee) ; Macho, Tomáš (advisor)
The goal of this paper is to create a functional soldering station, which would achieve the quality of commercialy available products. The design itself will not be satisfactory without sufficient knowledge of the field. Thus the introductory chapter focuses on a quick overview of matters concerning soldering The attributes are chosen based on market research. The station is equipped with a microcontroller. This allows implementation of usefull functions of several of the compered soldering stations. The practical part contains the electrical solutions and circuit board design. The program taking care of functionality of the entire product is described next. Control structure regulating the irons temperature was selected based on system identification. The result is a product, which satisfies all the requirements.

Examples of good practice in teaching English grammar through the inductive metod
MARTÍNKOVÁ, Markéta
The master thesis describes in its introduction the deductive and inductive approach to teaching English grammar, compares them, and also lists the pros and cons of each approach. The main content of the theoretical part is the presentation of key concepts and principles of inductive teaching of English grammar. The practical part converts theoretical knowledge to real grammar teaching. Pupils learned how to express past events within four lessons. These sample lessons are examples of good practice of teaching grammar inductively. The reflection of these lessons is provided at the end of this part.

The Study Increase Productivity
Marvanová, Barbora ; MBA, Štěpán Kalita, (referee) ; Jurová, Marie (advisor)
The topic of my bachelor thesis is to increase labour productivity with the focus on development of business, particularly in IFE-CR, a.s. Theoretical part describes particular company and deals with all basic concepts, terms and theoretical methods of solving problems associated with labour productivity. Analytical part discusses method of valuation of labour productivity which is done by IFE-CR, a.s. and analysis of labour productivity from different points of view. Final part includes my own concept of possible solutions with the aim of increasing labour productivity in the company.

Transient effect at the output of a linear dynamic system controlled pulse-width modulation
Petera, Martin ; Richter, Miloslav (referee) ; Jura, Pavel (advisor)
The goal of this work is to determine the size of overshoot produced at the output of a linear continuous second order system controlled by pulse width modulation. This work contains the calculation of the output signal response of the system in the time domain using the Laplace transform. The calculations of the amplitude of the output signal based on the pulse width modulation and system parameters are performed in this work. Finally the possibilities was given to determine the suitable period of pulse width modulation for required ripple. All the important calculations were compared with the simulations in the MATLAB-SIMULINK program and with the measurement at the real inertia second order cell.

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.

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.
