Design, production and testing of education model "Helicopter with two rotors"
Zouhar, František ; Šolc, František (referee) ; Grepl, Robert (advisor)
This work deals with designing and testing of education model "Helicopter with two rotors". The first part is focused on the consturction. Function requirement and set of options of solutions appointed. One of options is chosen and developed by 3D CAD systems. Balance-sheet of possible materials is elaborated in the maximum level available motor pull. Central placing of model is proposed to be able to move in 3 axes. The force electronic are designed and constructed in the second part. Suitable sensors, control method of motor speed and power support are chosen. According to this part the printed circuit board is created, which work as interface between PC (card MF624) and helicopter. In the last part model parameters are identificated and PID control is constructed. Selection procedure of parameters is analyzed in detail, each difficulties are mentioned and obtained data are evaluated. PID control is realized by degrees with regard to complexity of controlling the axes. Problems with disturbance and its impact on control is discussed also.

Simulator of current output 0-24mA
Mačišáková, Kateřina ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with design of very accurate current output simulator 0-24 mA with microcontroller with resolution 0.001 mA. In the thesis I deal with the market re-search with similar devices, theory and then with the conception of the whole system concept, with the identification of used components and with the evaluation of their suitability. I propose here a circuit diagram and a printed circuit board, which I then produce and install. For the resulting device I design and produce a box that will suita-bly complement and unify the entire system. I will revive the whole device, program it and test its functionality.

Integration of Loxone control system into a PV equipped residential house
Bačůvka, Petr ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
The bachelor´s thesis deals with the integration of a photovoltaic power plant into the electrical installation of an intelligent family house. The thesis basically explains the main differences in the connection of electrical installations of PV panels in houses. The basic components of a PV power plant and their functionality are mentioned. The main elements of this work are the control unit of the Victron PV power plant communicating with the Loxone miniserver. It uses the connection of the Loxone control system, with components from Loxone and Victron, to control the communication of individual components. The main communication interface is the Modbus communication protocol.

Gantry crane control via Modbus TCP
Arm, Jakub ; Štohl, Radek (referee) ; Kaczmarczyk, Václav (advisor)
Modbus TCP is a protocol for communication via ethernet bus. Goal of this work is realization of control of gantry crane model from personal computer. It is accomplished by Modbus converter, which communicates via ethernet bus. There are two ways of controlling. By graphic user application written in C# or by web pages running on created HTTP server. All services use created library, which is written in C language and communicates via Modbus TCP with Modicon Momentum unit. This unit interprets orders in form of Modbus protocol to controlling of standard industry inputs and outputs for process instrumentation. This process instrumentation is binded to control the gantry crane model.

Reservoirs - Brno, Zluty kopec (Yellow hill)
Bařina, Štěpán ; Dvořák, Tomáš (referee) ; Nový, Vítězslav (advisor)
This work deals with the elaboration of architectural and urban design of an area surrounding the historic water reservoirs in Brno – Tvrdého Street. The first part contains the urban design on the entire area, after that one specific building is processed in more detail in the form of an architectural study. The new use of the underground reservoirs is also a part of this project. The work is partly a continuation of older atelier work which was focused on an thorough analysis of the are and the possibilities of its development.

Human powered airplanes overview
Valuch, Tomáš ; Koštial, Rostislav (referee) ; Zikmund, Pavel (advisor)
In this bachelor thesis is elaborated historical development of human-powered aircrafts. The aim is to asses an overview of human-powered aircraft, to evaluate trends in the airframe structure and evaluate trends of specific design parameters. The first part deals with the historical development of the aircrafts. The next part focuses on the description of Kremer‘s prices and their importance for the development of this aircraft category. The following describes the structural components of the airframe and structural parameters. These parameters and flight performance are assessed. The last section is devoted to future developments and accomplishments records.

Remote Control of the PC via GSM modem
Chroustovský, Petr ; Štohl, Radek (referee) ; Kučera, Pavel (advisor)
The aim of the paper is to describe a creation procedure of such a system of remote control of a PC that would employ GSM networks. It also provides an analy-sis of the topic and conveys how to produce an electronic module that would enable the user with the basic functions of PC control, i.e. switching on and off the PC, using the functions of reset, sleep and wake-up modes of the PC employing a GSM network terminal. The paper also deals with the problem of comparing the possibili-ties of producing such a proposed system with commercially accessible hardware or software solutions available.

The Study of Inbound Logistics in Manufactoring Company
Voráčová, Eliška ; Litera, Petr (referee) ; Jurová, Marie (advisor)
The master's thesis is focused on optimal selection of transportation solution provider as a key activity of inbound logistics department of manufacturing company ABC s.r.o. The summary of general activities and objectives of inbound logistics are followed by the analysis of last selection procedure. Then there is mentioned suggestion of new selection procedure using the methods of Multiple Criteria Decision Making which is based on the knowledge from specialized logistical literature. This work assume that using the methods of Multiple Criteria Decision Making will result in more effective selection procedure in company ABC s.r.o.
