Automation of RC Models Control with Videocamera
Záň, Drahoslav ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
Nowadays, there is a big variety of RC models, but their use and control is basicaly the same. The aim of this thesis is therefore a modification of suitable RC model in such way, that it can be controlled via PC. The model is equipped with a computer plus video camera and using wireless technology is enabled video transmission into the final destination. This modified model can be used as a simple tool to explore an unknown terrain, or for spying purposes.

QoS in UMTS
Kavan, Radovan ; Hanus, Stanislav (referee) ; Kejík, Petr (advisor)
This thesis treats of QoS (Quality of Service) in UMTS system. The term quality of service is frequently used, recently, however not only in computer networks, but also more and more in mobile networks also. Present system of 2nd generation (2G) GSM enables only limited exploitation of QoS function. System UMTS is a system of 3rd generation (3G) already and contains quality of service in greater measure which is ensured with number of algorithms and functions. Individual QoS functions enable effective utilization of radio interface, support maintenance of planned coverage and offer high spectral efficiency. Functions that cater to quality of service are called RRM functions (Radio Resource Management). There exist five basic functions in UMTS system that are Admission control (AC), Power control (PC), Load control (LC), Handover control (HC) and Packet scheduler (PS). These functions are responsible for control of network access, control of power, control of network load, control of handover and packet (bit rate) scheduling. Last three functions are usually collectively designated as Congestion control, control of network overload. UMTS layer model, differentiation of services, traffic classes and 3GPP concept are also discussed. In thesis the attention is piad to Admission control algorithm – control of network access – in the uplink direction and to different ways of load (in the cell) modeling. Individual approaches are simulated in MATLAB. A possibility of using algorithm in the real system is discussed in conclusion.

Control and signalling unit for sport match
Bohutínský, Jaroslav ; Chmelař, Milan (referee) ; Kolouch, Jaromír (advisor)
The aim of this study is a design of a control and signalling unit for sport meetings controlled by a microcontroller. The unit should display the time, the state of the match, eventually another data important for a course of the match. It should be fitted by an audible alarm of the end of the match. A touch control panel with a liquid crystal display serves as input of control data. The unit operates in a countdown mode, it is possible anytime to start or to stop the time by pressing the button. The equipment is mains-operated and backed up by an external battery. In the case of a power failure, it is switched over to the battery. A representation of the time, the state of the match and other data is done by LED displays. The unit allows a connection to PC.

Ultrasonic distance measurement
Klich, Michal ; Krajsa, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The aim of this bachelor thesis is the design and manufacture of a controlling program of equipment for distance measurement using ultrasonic sensors. It focuses on a detailed description of the whole design from the basic properties of the components to the creation of schemes and PCB design. It subsequently describes in detail the development of controlling software of the equipment. The work briefly describes the most important parts of the code. It summarizes all theoretical and practical knowledge gained during the creation of the whole design, it explains the principles of the functions and works of individual parts and it suggests the best possible options of connection of the whole equipment. It also suggests the best possible variants of the entire circuit. The bachelor thesis also describes the microprocesor AVR ATmega8 from the Atmel Corporaton, which controls the entire device, as well as EEPROM memory chip 24LCXXX, SRF05 ultrasonic sensor and communication with the PC via USB using a microchip FT230XS-R.

Untitled Toy
Ambrůz, Kryštof ; Artamonov, Vasil (referee) ; Cenek, Filip (advisor)
Instalation is dedicated to nature, materials and technology. Using the post-internet aesthetics, i want show form which is not usual in our art environment. By creating imaginery laboratory, easily say place where the things arise or where we working on it, and with planed layout i want evoke impression like from the memorial places. Main place in this memorial occupies a table where every work from this year araised.

Web control system for textile machine
Balázsy, František ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This thesis deals with the design and implementation of web control application for textile machine. It consists of an HMI application based on the VueJS and Electron frameworks which communicates with the B&R PLC using the OPC UA protocol. For programming and production management uses MES microservice based on web realtime API. After it deals with deploying the application to a Linux station with kiosk configuration. The whole stack is implemented using JavaScript programming language and open-source software resources exclusively.

Grammar Systems and Syntax-Directed Translation Based on Them
Handlíř, Jaroslav ; Martiško, Jakub (referee) ; Meduna, Alexandr (advisor)
The thesis examines the theory of formal languages in the field of context-free grammars. It focuses mainly on the possibilities and models of collaborating grammars to solve a common problem. In this context, it presents grammatical systems that have been designed as a formal means for describing distributed and parallel processing. After introducing to the problematics, the thesis focuses on the practical use of these mechanisms in the translation controlled syntax, and therefore the second part of the thesis deals with the implementation of a dynamic syntactic analyzer that uses more grammars during the analysis. With respect to the greatest user friendliness and the possible didactic use, the application is implemented using modern web technologies HTML5, JavaScript, AngularJS, CSS3, LESS and more.
