Analysis of Wi-Fi traffic
Bakó, Zdeněk ; Pospíšil, Ondřej (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with the capture and analysis of wireless traffic of Wi-Fi networks. The aim of this work is to describe the possibilities of capturing and analyzing the operation of Wi-Fi networks. It describes the IEEE 802.11 standard, its features such as architecture and current standards. A selection of a suitable router is performed on which traffic capture and analysis is performed. Some open-source firmware for routers is compared and the most suitable one is selected. Tools for capturing and analyzing Wi-Fi network traffic are compared and described. The differences between the promiscuous and monitoring capture mode and their possibilities of use are described. Finally, there are described options for analyzing captured 802.11 frames.

Knowledge representation methods
Verbík, Josef ; Polách, Petr (referee) ; Jirsík, Václav (advisor)
This thesis deals with methods of knowledge representation within expert systems. The thesis describes the expert systems and their history. Furthermore, it provides a description of individual types of expert systems and their components. Following this description, there is a characteristic of the knowledge representation. These characteristic has been divided into two parts. The first part describes the requirements neccessary for efficient knowledge representation. The second part describes the following individual methods of knowledge representation: rules, frames, semantic nets and predicate logic.

The civil rights movement in Northern Ireland and its portrayal in the local periodical
Brčáková, Anna ; Váška, Jan (advisor) ; Šlosarčík, Ivo (referee)
The presented bachelor thesis concerns the topic of the media image of the civil rights movement in Northern Ireland in the local period press. The method of qualitative analysis and concept of frames is being used for the examination of the articles dealing with the five chosen important events in the period of the movement in the years 1968 and 1969. The events consist of the Caledon protest, the first civil rights march, the civil rights march in Derry/Londonderry, the announcement of a reform five-point plan, and the march of the People's Democracy. The thesis aims to explore the differences in the media coverage of these events in the periodicals of various socio-political orientations. Therefore, the selected newspapers include the most read titles with different editorial policies - traditional unionist leaning The News Letter (Belfast Newsletter), nationalist The Irish News, and liberal unionist The Belfast Telegraph. The analysis takes into consideration the amount, length, and placement of the articles, which indicates the level of importance of the event for the periodical. The main focus, however, is dedicated to the stance of the newspapers on the movement. Therefore, a system of categories is used to indicate sympathy or antipathy for the events. Moreover, the frames used for the...

Storytelling and Reconciliation: Shifts in Frames and Discursive Narratives in Listeners of the Initiative "My Story" in Bosnia and Herzegovina
Oberpfalzerová, Hana ; Aslan, Emil (advisor) ; Stojarová, Věra (referee) ; Kubátová, Hana (referee)
Storytelling and Reconciliation: Shifts in Frames and Discursive Narratives in Listeners of the Initiative "My Story" in Bosnia and Herzegovina Hana Oberpfalzerová Abstract In Bosnia and Herzegovina, two non-governmental organizations have been running the initiative "My Story" within which three war victims, one Bosniak, one Serb and one Croat, tell their wartime stories and their way to reconciliation in public testimonies in a side-by-side, live setting to an audience of young people or ordinary citizens. The aim of the initiative is to promote reconciliation in the listeners. This doctoral dissertation integrates several disparate fields in order to create an analytical framework for inferring attitude shifts from the discursive narratives recalled by the listeners, and from the frames that connect the single narratives to broader societal discourses within these discursive narratives. Three public testimonies were analyzed and interviews with eighteen listeners from the three Bosnian nations were conducted, some of which were interviewed by phone about four months later to check for further attitude changes. The interview material was analyzed inductively by the means of thematic discourse analysis in order to identify the underlying discursive narratives that were then regrouped into dimensions or...

From the world cup to the olympic games in Brazil: security and safety lessons learned
Bonk, Marián
In todays world, which is full of conflict, security is an phenomena which directly deals with issues such as conflicts, wars or simple public security on daily basis. It is then clear that in some cases the security itself will be perceived with even greater seriousness. The goal of this bachelor thesis is to analyse the security measures and frameworks implemented for two sport mega-events which both took place in Rio de Janeiro, Brazil. These two events are the 2014 World Cup and the 2016 Olympic Games. Another step is comparison of gathered results which means comparison of specific attitudes, approaches, frameworks and ways in which the security was ensure. The last step is an interpretation of results via Final comparison and Conclusion which is going to indicate, whether there were any similarities or changes in designed frameworks and what frameworks exactly were designed according to which parameters.

Knowledge Representation
Blecher, Jan ; Jirků, Petr (advisor) ; Berka, Petr (referee)
Tato práce se snaží priblížit jednotlivé metody reprezentace znalostí v umelé inteligenci s durazem na obecný prehled a rozdíly mezi jednotlivými metodami. V textu jsou rozebrána schémata reprezentace znalostí, mezi která patrí predikátová logika, produkcní systémy, sémantické síte a rámce. U každého schématu jsou uvedeny jeho charakteristické vlastnosti a nekteré typické metody. Z textu je zrejmé, že opravdu neexistuje žádná univerzální metoda reprezentace znalostí, ale naopak, že jednotlivé metody jsou vhodné pro konkrétní situace reálného sveta. Nekteré oblasti znalostí dokonce nejsou klasickými schématickými metodami, které uvádím v tomto textu, reprezentovatelné vubec nebo jen velmi težko. Práce je rozdelena dle jednotlivých metod reprezentace, které jsou dále strukturovány s ohledem na postupy v nich používané.
