Hacktivism: Politics, Crime, or Fun?
Raška, Jindřich ; Froehling, Kenneth (oponent) ; Kotásek, Miroslav (vedoucí práce)
The aim of the thesis is to analyze the phenomenon of hacktivism, its purpose, its impact on society, and the motivation of its participants. The term hacktivism comprises terms activism, in most cases political, and computer hacking, a criminal act aimed at exploiting a computer system. Hacktivists are mostly, like any other activists, organized in groups to effectively achieve their goals. This study focuses on the origin, motivation, and consequences of the hacktivist actions, especially on actions of an infamous group called Anonymous, including exemplary cases from history.

Life management of power oil transformer
Čechová, Karolína ; Froehling, Kenneth (oponent) ; Sedláček, Pavel (vedoucí práce)
To understand the significance of the life management process concerning power oil transformers, at first, it is essential to realise their role in the electrical grid. They are primarily used to interface step up and step down voltages in the transmission and distribution system according to the contemporary needs. The unreliability of power oil transformers can disrupt the stability of the electric power supply, which represents significant economic and technical losses for companies that manage this type of equipment. Therefore, I decided to write a thesis that provides an overview about the life management process by describing its economic benefits along with technical diagnostics, which help to identify incipient defects at their early stages that may arise during the operation of power oil transformers. The main aim of this thesis is to describe and prove the importance of the life management process itself and the need to analyse transformer parameters by diagnostic methods to detect possible defects. The practical part of the thesis focuses on proposing the most suitable diagnostic methods for measuring the selected parameters of the chosen power oil transformer. The selected parameters are then analysed, and the overall condition of the chosen power oil transformer is estimated.

Industrial Tester for Photometric Values of LED diodes Used in Automotive Signal Lighting
Gaži, Dominik ; Froehling, Kenneth (oponent) ; Baumgartnerová, Alena (vedoucí práce)
Headlamps in cars have been through an enormous technical development in recent years, and with development comes complexity. Various technologies are employed in order to deliver progressively safer and more efficient light output, to satisfy drivers and customers alike. In order to be economical and environment-friendly, companies strive to minimize losses in production. For the sake of the minimalization, this thesis aims to research the lighting technology and design a simple, but effective device to help with determining of faulty LED PCBs in headlamps. Another objective is to research the possibilities of construction of such a device from technological standpoint.

The use of robotic Rovers to explore Mars
Pekař, Štěpán ; Sedláček, Pavel (oponent) ; Froehling, Kenneth (vedoucí práce)
This Bachelor´s thesis focuses on three space missions: Mars Pathfinder, Mars Exploration Rover, and Mars Science Laboratory. The main part of these three missions are four rovers (Sojourner, Spirit, Opportunity, and Curiosity) that have been sent to the surface of the Red Planet. The thesis is focused especially on the scientific tools of the individual rovers, the technology used and on the most important scientific knowledge gained during the missions on Mars.

Social Media and their Influence on Democratic Elections
Khyzhniak, Veronika ; Žouželková Bartošová, Marie (oponent) ; Froehling, Kenneth (vedoucí práce)
Progress in online technology has greatly improved the way how people all over the world can communicate with each other. Social networks greatly facilitate live communication not only for ordinary people but also for representatives of the legislative power. With the help of social media, politicians can promote their political campaign, advertise their party and, thanks to this, quickly and economically gain supporters. The 2016 US presidential elections highlighted the importance of social media communication on democratic elections worldwide. The aim of the thesis is to study different forms of social media. The project deals with the impact of Twitter and Facebook in the 2016 USA election and describes the way candidates were using it during the race.

Science Fiction and the Prediction of Technology, Past and Present
Skorobogatova, Margarita ; Sedláček, Pavel (oponent) ; Froehling, Kenneth (vedoucí práce)
The aim of this bachelor thesis is to examine if science fiction can predict future technologies. The first chapter introduces science fiction writers of the 19th and 20th centuries, who predicted a variety of technological inventions, that can be found in the present. The second chapter deals with science fiction cinematography, outlined and supported by examples taken from science fiction films and television series. The last chapter is based on diverse technological inventions of the present, which are described and demonstrated by the directors of science fiction movies and which are considered as the most likely examples that can be implemented in the near future. The conclusion describes the outcomes of the conducted studies and defines possible development in the future.

The Use of 3D Printers in Medicine
Shchennikov, Vladislav ; Froehling, Kenneth (oponent) ; Šedrlová, Magdalena (vedoucí práce)
The text deals with the rapid development of three-dimensional printers, description of their general components, and the utilization of 3D printers in medicine. In our contemporary world, three-dimensional printers have appeared more recently and immediately were applied in various fields and industries. 3D printing is an innovative and forward-looking technology that will unimaginably change people’s lives and will reduce an enormous amount of time and resources, that is spent on creating certain products. The opportunity of using such technology in different areas, particularly in medicine are described in this bachelor thesis, as well as the differences between individual technologies and their advantages and disadvantages.

The Technology of Subtitles in Films and other Media
Tobiášová, Eliška ; Jašková, Jana (oponent) ; Froehling, Kenneth (vedoucí práce)
The purpose of the bachelor’s thesis is to explore subtitling technology. This is analysed from a historical, present, and future perspective. The research also mentions specific ways of using subtitles for certain types of media and it also includes an analysis of the target groups for which the subtitles are intended. In addition to theoretical research of subtitling technology, an experiment is conducted to assess the accuracy of subtitling between machine-generated subtitles, professional work, and amateur work. This is achieved by comparing subtitles from the same film scenes side by side in tables. The result of the research, which is derived from the criteria mentioned in the work, shows that professional subtitles are the most reliable way.
