Upgrading the Subsystem for Testing of the Safety Function of a Valve
Němec, Petr ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
The aim of this work is to develop a theoretical basis for the modernization of the subsystem for testing the valve function, the subsequent design and implementation of the visualization. The thesis briefly describes the steam turbine circulation and bypass technology. Thus, the technology of the system in which the safety function itself is located. Furthermore, the thesis deals with the functional safety analysis and describes the development of three analysis methods FTA, HAZOP and FMEA. The thesis also deals with the analysis and description of an existing application using a state diagram. From the subsequent analysis, the design of a new visualization is realized. The visualization is tested in the thesis using simulation which is performed on a real PLC and also using PLCSIM software.

Occupational therapy program to develop the skills of a child with a physical disability for the transition from kindergarten to primary school
Veselá, Markéta ; Hájková, Vanda (advisor) ; Valešová Malecová, Barbara (referee)
This thesis deals with the evaluation of a self-designed occupational therapy programme to support children with physical disabilities in their transition to primary school. The aim of the research is to test the effectiveness of this programme. The theoretical background explores the concepts of occupational therapy and physiotherapy in educational settings, their role in paediatrics and the impact of physical disability on school adjustment. It also focuses on the importance of movement, sensory integration and well-being in relation to successful school adjustment. The transition to primary school for the child with physical disabilities and the preparation of the family environment and the child itself for this step are other topics of this thesis. A further aim is to determine whether the programme can be used by teachers as part of an educational curriculum. The final section shows how an occupational therapy programme can be integrated into the regular school environment and how it can contribute to the successful integration of children with physical disabilities into a new school environment. The methodological section describes the research methods used, including intervention evaluation research and the plan for testing the programme. The empirical section then presents the occupational...

Design and implementation of a platform for control LLC-type inverter with a wide input supply voltage range using a FPGA circuit
Pokorný, Ondřej ; Levek, Vladimír (referee) ; Prokop, Roman (advisor)
This master’s thesis deals with the emulation of LLC converter control with a wide input voltage range using a created emulation platform. The first part of this work is focused on the design of resonant converters with a wide input voltage range. Based on theoretical knowledge, an adjustment of the emulation LLC converter is made. The converter modification is concluded with a simulation, where the correctness of the design and the fulfillment of the ZVS parameter in the entire input voltage range are verified. In the next part of the work, an analysis of the control issues of resonant converters, more precisely LLC type resonant converters, is carried out. The acquired knowledge is used for the design of a new emulation platform, which will serve for the emulation of LLC converter control with a wide input voltage range. The last part of the work is the creation of an emulation program for FPGA in SystemVerilog language. The work is concluded by verifying the functionality of the emulation on physical hardware.

Automation of the calibration process
Mařas, Michael ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
This master thesis deals with the automation of the calibration process at the workplace for calibration of electronic power meters and the description of the method of evaluation of calibration results. The paper analyses the calibration workstation and the manual method of calibration performed by the calibration laboratory staff. Furthermore, proposals for automating the manual method of calibration and a description of the implementation of a program for automating this process are given. Subsequently, the uncertainty analysis is described in the paper. In this section, the uncertainty analysis according to the GUM method and the subsequent calculation of these uncertainties are presented. The correctness of the calculation of uncertainties according to the GUM method is verified by the Monte Carlo method. In the last part of the work, the method of evaluation of the calibration results according to ILAC-G8:09/2019 is described and the form of the calibration protocol is described.

Cross-border cooperation between Šumava National Park and Bavarian Forest National Park
JERHOTOVÁ, Vendulka
The bachelor thesis deals with cross-border cooperation between the Šumava National Park and the Bavarian Forest National Park. The projects focus mainly on nature conservation, monitoring of animal, fungi or plant species, environmental education and the construction of nature trails; the activities are largely supported by European funds. The text also deals with regional policy, Euroregions and forms of cooperation. The development of individual national parks and their approach to nature conservation is also covered.

Checking SQL Code Properties
Bali, Filip ; Bartík, Vladimír (referee) ; Rychlý, Marek (advisor)
This thesis focuses on checking the properties of SQL code based on static analysis using predefined rules. The rule represents a basic element of the check. The user can define their own rule and include it in the check. A rule usually contains a set of conditions that are contained in an algorithm that checks nodes in an abstract syntactic tree. Abstract syntactic tree is created from an input SQL statement and customized so that rules can be applied over its nodes. If the rule detects an error, then it can generate a report. These reports are then displayed on the selected output. Based on the thesis, an open source program in the Python3 programming language was implemented. This program is publicly available.

Creation of a program code for evaluation and display of inner resultants in beams
Kupka, Jiří ; Horníková, Jana (referee) ; Burša, Jiří (advisor)
The work is aimed at solution of problem with evaluating the values and courses of resulting inner effects. The goal is to algorithmize the calculation and its graphic interpretation. The main mphasis was on the correctness of numerical results and their correct depiction. Integral approach of olution and its logorithmization was chosen as suitable calculating model for given task. The algorithmus of the program itself was written in programming language C++. Thereinafter the basis of the sphere of tress and strain analysis in beams, the knowledge of which is neccessary for the given solution of the roblem or it is presumed.

Use VBA as a Tool for the Creation of Supporting Business Applications
Märtzová, Alexandra ; Neuwirth, Bernard (referee) ; Dydowicz, Petr (advisor)
The bachelor thesis focuses its goal on description and implementation of the information system application of the organisation financed by the state budget. After analysing the existing information system, change recommendations were proposed, that meet the norms, standards, and organisation requirements. Subsequently, the recommendations were implemented into application suggestion. The solution aim to automate data storage and search processes, transform related data into visual presentation, and thus reduce the length time of customer service.
