Markedness in the language of Czech political podcasts
Johová, Lucie ; Jirák, Jan (advisor) ; Schneiderová, Soňa (referee)
The master's thesis focuses on the markedness in the language of Czech political podcasts. The aim is to find out how contemporary political journalists enrich their vocabulary and how they utilize creativity, humor, irony, and updating expressions in their speeches. The theoretical part defines the functional journalistic style and its historical development, as well as the concept of stylistic markedness and the principles of identifying marked linguistic means. The work also examines the role of podcasting as an important media phenomenon of the 21st century and its relationship to the traditional audio medium - radio. The analytical part applies these findings within the framework of a qualitative analysis of the language of speakers in selected political podcasts. It focuses on their inventiveness in using linguistic means and reflects the current language situation and trends in enriching vocabulary in the public space. The results show how speakers use updating expressions in their speech and to what extent they resort to standardized expressions. The master's thesis provides a valuable overview of the current state of language in Czech political podcasts and contributes to a better understanding of the role of podcasting in the Czech media landscape.

Darkmarket Forensics
Dolejška, Daniel ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
Overlay networks (like Tor or I2P) create a suitable environment for criminality to thrive on the Internet. Dark marketplaces (a.k.a. cryptomarkets) are one such example of criminal activities. They act as an intermediary in the trade of illegal goods and services. This project focuses on forensic analysis of such web services and subsequent extraction of non-trivial information about the realised orders and payments from selected marketplaces. The main goal is to pinpoint the time interval when an order has been completed on selected marketplaces and its following correlation with cryptocurrency blockchains. The implemented program provides fully automated non-stop monitoring of selected cryptomarkets. That, under certain conditions, allows detection of realised purchases, detailed product and vendor monitoring and collection of various meta-data entries. Law enforcement agencies can use acquired data as support evidence regarding the operation of selected cryptomarkets and their vendors. The obtained information can also indicate current trends in products supply and demand.

Programmable Relay in the Application of Automated Production Tests
Ondruška, Arnošt ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
This Bachelor thesis describes the design of a programmable relay and its application in the automation of production tests. First, commercially available, professionally produced relays are presented and selected bachelor and diploma theses related to the issue of automated measurement of electrical quantities are summarized. The thesis presents the design of an automated test workplace containing measuring devices, laboratory sources and other accessories controlled by a programmable relay via RS 232, with minimal human intervention. A block diagram is presented in the work, and individual blocks are subsequently described in detail. The output of the work is the creation of a custom design of a programmable relay and its use in automated measurement and control of the properties of serially produced industrial sources for the energy industry. The test program itself is written in the BASCom-AVR language.

Design of a smart house control system
Ovesný, David ; Burian, František (referee) ; Fiedler, Petr (advisor)
This bachelor thesis deals with the comprehensive design solution of a smart home using Loxone technology. Through the appropriate implementation of sensors, actuators, and a central control system, a comprehensive solution for home automation processes is proposed. The theoretical part introduces Loxone technology and briefly compares it with the competing ABB free@home technology. The practical section involves the selection of suitable hardware components and the description of control algorithms. The conclusion of the thesis is dedicated to a cost comparison with the competing technology.

Production technology for a vacuum pump component
Horák, Adam ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
The bachelor's thesis focuses on the design of a new or alternative technology for the component of the orbital scroll wheel 10i for the vacuum pump nXDS10i. The component is made of an aluminum alloy. The aim is to transition to a higher level of automation compared to the original technology, with the implementation of High-Speed Cutting (HSC) machining. The thesis includes an introduction and analysis of the component, including information about the alloy used, an analysis of the original technology, and its variants for optimization. This is followed by the proposal of a new technology and automation design, meeting the conditions set by the manufacturer of the component. The proposal of the new technology includes the design of a new technological process and clamping method. The thesis also includes a technical and economic evaluation of the original technology, the optimized original technology, and the new technology.

Analysis of the procedure for identifying potentially dangerous locations of weld joints in thin-walled metal structures during life assessment
Doležel, Daniel ; Pavlík, Ondřej (referee) ; Vosynek, Petr (advisor)
Hodnocení únavy svarů u tenkostěnných kovových konstrukcích je klíčové pro zajištění integrity navrhovaných konstrukcí. Navzdory zavedeným kritériím a S-N křivkám může být analýza životnosti svařovaných spojů u geometricky komplexních součástí značně komplikovaná. Hlavní překážkou je identifikace kritických míst z hlediska únavy pro detailní výpočet, což může být časově náročné i při využití metody konečných prvků (MKP). Tato práce podrobně zkoumá hodnocení únavy svarů, zahrnuje vhled do relevantní literatury, komerčních řešení a praktický kontext norem železničního průmyslu a směrnice FKM. Významným přínosem práce je vývoj automatizovaných FEMAP API programů pro MKP software Siemens FEMAP, které usnadňují proces analýzy. Tyto programy šetří čas a úsilí tím, že umožňují zjednodušenou analýzu založenou na konceptu lokálního nominálního napětí (local nominal stress) v souladu se směrnicí FKM. Metodika, podpořená vyvinutými programy, je v této práci popsána a prakticky demonstrována. Praktické přínosy této práce spočívají v poskytnutí alternativy ke komerčním softwarům, za účelem zvýšení efektivity analýzy životnosti svarů v kontextu konstukčních návrhů.

Virtual commissioning of robotic production system for arc welding
Hrubeš, Kryštof ; Szabari, Mikuláš (referee) ; Bražina, Jakub (advisor)
This thesis focuses on the design and virtual commissioning of a robotic system for arc welding. The theoretical part of the thesis is dedicated to a review of the current state of knowledge in the field of welding, with a particular emphasis on arc welding in robotics. Additionally, the review addresses the issue of virtual commissioning. In the system analysis chapter, key components of the workstation such as welding torches, power sources, wire feeders, and safety equipment were analyzed. Based on a multicriteria analysis, the optimal system variant was selected. Using the ABB Robot Studio software, a detailed model, HMI, and control algorithms were created, enabling the simulation and optimization of the welding process. In the final step, virtual commissioning was carried out in the ABB Robot Studio environment.
