Integrated Measurement System for In-Field Compliance Testing
Chvalová, Aneta ; Morávek, Jan (referee) ; Dvořáček, Jiří (advisor)
As the number of renewable energy sources has increased, new installations have been subject to new requirements for their control, whether autonomous (responding to conditions at the point of connection) or dispatchable. An important step for the commissioning of photovoltaic (PV) plants is to perform compliance testing, which is sometimes only appropriate or necessary to perform in the field on a complete installed plant. The measurements are used to obtain a set of data which is then used to issue a certificate of correct operation (i.e. compliance with requirements). The main output is a measurement system assembled into a portable case that can be easily transported to the PV installation site and simply connect the measurement analyzer to both the AC at low voltage level (for recording voltage, current, power, frequency) and DC (for recording binary commands and signaling). Also included is elaborate documentation of the case itself.

Application for Exam Preparation
Líbal, Tomáš ; Veigend, Petr (referee) ; Dytrych, Jaroslav (advisor)
This thesis deals with the issue of preparation of final exams at the Faculty of Information Technology of Brno University of Technology. It describes the process of design and implementation of a web application that allows teachers to create and manage room schemes and terms of individual exams. An important part of the application is also the automatic placement of students in the rooms and the generation of individual exam assignments for printing based on the given template and the method of placement. The application provides students with a clear view of individual exam terms and details about them. The work will result in a functional and usable web application written in Java using the Spring and Angular frameworks.

Generation of Voltage Wave by Impulse Generator
Poloni, Miroslav ; Krbal, Michal (referee) ; Pelikán, Luděk (advisor)
The presented bachelor thesis deals with the problems and functions of impulse voltage generators. The theoretical part describes the functions and various connections of the impulse generator, types of impulse voltage, tests and test procedures. In the practical part of the work, theoretical knowledge in the form of simulations was verified. The simulations were performed in the LTspice program from Linear Technology, where the impulse generator model was made. Simulations were then performed on the given model of the shock generator, from simpler ones such as the dependence of the size of the load capacity to the inductance connected in parallel. The results of all simulations should bring benefits and ease in real shock generator tests

Welding technology of turbine rotors
Pivoňka, Vít ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The paper deals with all the possibilities which can be used to weld the rotors of turbines, both the root and the filler welding. All these methods are thoroughly analyzed and their properties are described, especially the size of the heat input by welding of rotors of turbines. Further in this work is described the organization of the structure by means of a metallographic survey and a test of welds and materials, which are performed to check whether the material and the welding method are suitable for welding of rotors of turbines. In the experimental part are described all welds made by different welding parameters, one of these welds is chosen to achieve the best welding of the weld root. This weld is further investigated for hardness and change of microstructure after welding.

Entrepreneurial Project
Čechová, Jitka ; Novák, Zdeněk (referee) ; Rompotl, Jaroslav (advisor)
The aim of this diploma thesis is to develop a business plan in order to set up an educational centre with a range of courses, through which the market will be accommodated there where the school education system is not sufficient. The first part focuses on the theoretical knowledge and is followed by more detailed analysis of the current market situation. In a proposal part, there is a detailed entrepreneurial plan, according to which the plan feasibility can be considered.

Manufacturing technology of rail vehicle by new adhesive systems
Tesař, Petr ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
This master´s thesis deals with the bonding process, which is the dominant technology of the production of door leaves for railway vehicles. Following the necessary study of the basic essence of bonded joints the thesis further introduces the individual construction options of this product. The essential part of the thesis is represented by presentation of the achieved results of the testing of individual selected types of adhesives. On the basis of these results the most suitable type and supplier of industrial adhesive is selected.
