Water Management Analysis of Storage Capacity of the Vranov Reservoir
Vítková, Lucie ; Havlík, Martin (referee) ; Marton, Daniel (advisor)
The current persistent drought and changes in the climate system have raised water managers expert questions about how to manage water resources in the future. The manifestation of climate change in hydrological series and their influence on the magnitude of threats to the storage functions of reservoirs are more often investigated. Already today, long-term shortages of storage capacity in reservoirs lead to the introduction of special manipulations on water structures. The aim of the thesis is to perform the analysis of time series, respectively decomposition of hydrological series average annual and monthly discharges. Create extended hydrological bases using synthetic discharge series generators and develop a comprehensive analysis of storage volume without considering losses even with the introduction of losses from the water surface vapor in the UNCE RESERVOIR program. The created discharge series are compared and evaluated on the basis of statistical characteristics and reservoir storages results with the real discharge series. The practical app is conducted on the Vranov reservoir in the Dyje River Basin.

The phenomenon of hybrid activities of state and non-state actors
Havlík, Martin ; Hynek, Nikola (advisor) ; Ludvík, Jan (referee)
The rigorous thesis deals with the issue of hybrid action of state and non-state actors using a wide range of tools of power to promote their own interests. The primary intention is to relate the content to the concept of security according to the Copenhagen school, which was one of the most important in the second half of the 20th century after the collapse of the bipolar world order to expand the dimensions of security. The definition of the main concepts of security is further extended by Clausewitz's concept of war and the American concept of Theory of Victory. The introductory theories are followed by an analysis of key theoretical apparatuses of important Western, Russian and Chinese security experts, which are then compared in relation to the essential factors of individual hybrid approaches. The work further describes in detail the significant categories of tools such as soft power, hard power, smart power and sharp power. An important part of the work is also the analysis of state, non-state and proxy-state actors, as the main carriers, users and representatives of hybrid action. In this context, the key determinant is the chosen reference object in the form of the Czech Republic. To complement the issue, the work also includes the related area of facing hybrid threats and hybrid action...

Tool for Management of Flash Memory Wear-Leveling on Embedded System Device
Havlík, Martin ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Práce se zabývá mechanismem wear leveling nad pamětí typu flash, zejména implementací poskytovanou společností Espressif v rámci IoT Development Framework, a to s cílem vytvořit nástroj pro sledování opotřebení flash paměti způsobené operacemi mazání. Pro účely tohoto nástroje je vytvořena vylepšená verze mechanismu, řešící některé nedostatky a rozšiřující původní wear leveling poskytovaný společností Espressif. Vylepšení zahrnuje možnost sledovat opotřebení paměti s rozlišením jednotlivých sektorů a zavádí pseudonáhodnou složku do mapovacího algoritmu za pomocí šifry zachovávající formát založené na nevyvážené Feistelově síti, vedoucí k rovnoměrnějšímu rozložení operací mazání po paměti. Toto pseudonáhodné mapování je následně otestováno pomocí simulace životnosti paměti ve vybraných zátěžových scénářích, s výsledky vykazujícími až pár procentní vylepšení v rovnoměrnosti opotřebení oproti původnímu algoritmu. Závěrem je vytvořen nástroj pro sledování opotřebení flash paměti, sestávající z vestavěné back-end části a PC front-end GUI vizualizační části.

Turn-taking in distance teaching
Svašková, Anna ; Nekvapil, Jiří (advisor) ; Havlík, Martin (referee)
This bachelor thesis aims to describe some of the phenomena occurring during distance learning, predominantly when it comes to turn-taking. Based on some previous literature, the first chapters of the thesis introduce conversation analysis and its view on classroom interaction and computer-mediated communication, then also turn-taking including its particularities during videocalls and then the characteristics of interaction during distance learning specifically as well. The next part of the thesis introduces a conversation analysis research of distance learning recordings, which is focused on the issues of distance learning such as overlaps or a limited access to non-verbal communication, then also on its advantages such as the presence of the chat channel, then on the strategies that are used when teachers try to hand the floor over to the students, including giving some kind of hint, assigning the next speaker or adding a sub-question, and finally on the ways in which the teachers react to the students being silent, where the result is either needing to explain the matter or the silence being a sufficient form of response.

Extreme Case Formulations in the Research Interview
Zaepernicková, Eliška ; Nekvapil, Jiří (advisor) ; Havlík, Martin (referee)
The following thesis analyses the form and importance of extreme case formulations based on more than 10 research interviews. Extreme case formulations, i.e. formulations comprising expressions such as "nothing", "everything" or "noone", which present a phenomenon or a circumstance according to its minimal or maximal properties, can constitute a complication in the analysis of research interviews. This thesis expand the existing hypothesis of extreme case formulations by adding new findings, for example the bipolarity of extreme case formulations. In the analysed data, these do often occur together with different clasifiers, which either weaken (softeners) or strengthen (intensifiers) their extreme force. At the same time the following thesis broadens the research of extreme case formulations of interdisciplinary approach, which uses the findings from psychology and rhetoric. The conducted research is furthermore completed with the acoustic analysis of semantically extreme formulations, whose results show that extreme case formulations often tend to be acoustically emphasized. Keywords: extreme case formulation, conversation analysis, discourse analysis, interview, Czech

Sequential and Prosodic Aspects of Conversation
Havlík, Martin ; Nekvapil, Jiří (advisor) ; Volín, Jan (referee) ; Zeman, Jiří (referee)
This study deals with two phenomena which are closely related to the turn-taking mechanism in conversation. These are: overlapping talk and the use of prosody in turn-taking. Prosody is linked to the formation of the transition relevance place. I point out the aspects of conversation, including prosody, which shape the transition relevance place, and also how prosody is used in the projection of turn-yielding, or turn-holding. I devote attention to three basic aspects of prosody: pitch movement, intensity movement and articulation rate. Furthermore, I analyze how overlapping turns are produced, how they proceed and how they are resolved. The characteristics of overlapping talk are influenced by the types of conversation in which they occur: while in mundane, informal conversation they can last only briefly, usually produced as a means of mutual understanding, in political debates they are often prolonged, as they are associated with the efforts of speakers to take and hold the floor.

The ability to react to coherence disruption in communication with chatbots of czech users
Maršík, Albert ; Havlík, Martin (advisor) ; Lehečková, Eva (referee)
The subject of this paper is to create a terminological methodological interface for a complex description of the understanding conversation. The first task is an attempt of fusing two relevant branches of research - text syntax and conversation analysis. Text syntax describes structures larger than a sentence and brings useful remarks about links between elements in the text and its thematic progression. Conversation analysis concerns itself with interaction specifically and does so from a partially sociological perspective. It offers the especially useful notion of sequence organization. The other task for this paper is to create a conversation tool, a chatbot, that the researcher will have control over and which allows them to expose multiple speakers to an identical or at least similar conversation situation. Written communication, where human takes turns with an "artificial intelligence" has many specificities. The temporal aspect is fully substituted by chronology here. Coherence disruptions have a bigger potential to be perceived as such, because users expect technological problems, whereas in human interaction the speakers typically tend to trust each other in their motivation to communicate coherently. Nevertheless one must approach human-ai conversations in a different way than the...
