Virtual commissioning of the robotic workplace for workpiece manipulation
Lorenc, Tomáš ; Szabari, Mikuláš (referee) ; Bražina, Jakub (advisor)
The diploma thesis deals with the issue of virtual commissioning of the workplace and the commissioning of communication channels needed for this purpose. The theoretical part describes the benefits of virtual commissioning, robot and PLC programming and effectors for robots. The practical part deals with the design of the final robot effector, virtual commissioning using the programs Process Simulate and TwinCAT 3, communication between programs and creation of programs for the workplace.

Analysis of manufacturing of component by elastoforming technology
Lorenc, Tomáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
In this thesis, processed within the master's degree is the analysis and proposals for modification of production stagnation ribs aircraft L-410. The part is made of aluminum alloy D16. More specifically, it is a 0.8 mm thickness sheet, which after the milling of the blank molded in the basic non-rigid tool by Guerin. After analyzing the entire manufacturing process and the determination of the critical points due to a series of tests carried out were evaluated possible variants production innovation. Proposed changes and their optimization can reduce the labor intensity deleting some time being necessary preparatory and finishing operations manual. It also increases the repeatability and streamline current production panels.

Sheet Metal Stretch Forming Process
Lorenc, Tomáš ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
In this work, elaborated in the bachelor study, there is a general overview of the sheet metal stretch forming methods. The stretch forming processes shift the boundary properties of the materials and merge process of drawing and bending into one operation. That's why it's possible to do products from materials, which can not be possible to form by other methods in the same quality Positives of this technology are the minimization of cushioning, the production of complex, precise surface shapes, etc. The contribution of this work is a systematic summary of the principles that should be used as a tool for teaching or as a basis for the wider development of this method.

Performance Measurement of LoRa/LoRaWAN Communication
Lorenc, Tomáš ; Kubíček, Michal (referee) ; Povalač, Aleš (advisor)
This project focused on describe LoRa/LoRaWAN wireless communication that enables power-efficient wireless communication over very long distances. It describes also LoRaWAN infrastructure The Things Network for merging several LoRaWAN devices into one network. The practical part defined measuring equipment, chosen electric parts, and final realization. The main goal of this work is a performance and range measurement of LoRaWAN communication by change communication options. The experiment result is compared with theoretical results. It generates an interactive map of radio range from the experiment result.

Analysis of the Decisive Factors Influencing the Usual Price of Selected Houses in Břeclav
Lorenc, Tomáš ; Gardášová, Alena (referee) ; Komosná, Milada (advisor)
The diploma thesis deals with decisive factors effecting the usual price of family houses in town Břeclav. The long-term research was conducted on Czech real estate server Sreality.cz and on the server of Czech Office for Surveying, Mapping and Cadastre cuzk.cz. Based on this research the situation on real estate market was described in details in the thesis and the databases were built. Furthermore, the administrative price and the usual price were determined for three chosen family houses located in different parts of the city (in Břeclav center, in Stará Břeclav, in Poštorná). The final part of diploma thesis is devoted to the analysis of critical influences, especially the influence of the location. Both of comparison of results from individual parts of the city and comparison with existing knowledge found by search activities were made.

Design of adaptive wireless video and data transmission
Lorenc, Tomáš ; Nykodým, Jiří (referee) ; Götthans, Tomáš (advisor)
Cílem této diplomové práce je sestavit zařízení, které bude umět vytvořit bezdrátový přenos real time videa a posílat video do počítače, kde bude zobrazeno. Zařízení je postavené na jednotce NVIDIA Jetson Nano a vysílání videa probíhá bezdrátově pomocí WiFi rozhraní. V teoretické části je popsána problematika přenosu videa a komprese videa. Používají se kodeky h264, h265 a VP8. Byl proveden subjektivní test pro nalezení minimální akceptovatelné hodnoty kvality videa. Bylo provedeno měření, které odhalí nejlepší kodek pro real time přenos videa. Měření probíhalo i v reálných podmínkách. V závěru jsou komentovány výsledky měření a výběr nejlepšího kodeku pro real time video přenos.
