An Extended Model of a MEMS Gyroscope: Design and Identification
Vágner, Martin ; Sopata,, Milan (referee) ; Tůma, Jiří (referee) ; Beneš, Petr (advisor)
The thesis is aimed on measurement and modeling of MEMS gyroscopes based on input-output characteristics. The first part briefs the state of the art. The second part is dedicated to measurement methodology. Critical points and sources of uncertainty are discussed and evaluated using measurements or simulations. The last part shows key characteristics of MEMS gyroscopes based on the survey of a group of different sensor types. The results have revealed significant influence of supply voltage that causes bias drift of the gyroscope and bias drift of the internal temperature sensor. The error can be comparable to temperature drift; however, this effect is not addressed in the literature. The second observed effect is temperature dependency of angle random walk. In the last part, a general model of a MEMS gyroscope is rewritten to reflect observed effects. Moreover, the structure is selected to be easily extendable and the coefficients are expressed to allow a comparison of nominal parameters of different sensors.

Explainable Convolutional Neural Networks
Kamenický, Daniel ; Herout, Adam (referee) ; Hradiš, Michal (advisor)
The aim of this work was to compare several methods for visualizing the features of each class on the input pixel layer of the CNN. Each method uses a different algorithm, based on gradients, to compute the resulting values. Using the implementation of each method, the resultant values of the methods are obtained by using the equation of energy concentration. The resultant values are presented in tables and graphs from which the success rate of the result of the work can be read. The difference between the methods and comparison of their results can be read from the work. This makes it possible to get an overview of gradient based visualization methods.

Representation of the Israeli-Palestinian conflict in Czech media coverage
Lacina, Jiří ; Nečas, Vlastimil (advisor) ; Končelík, Jakub (referee)
This master's thesis focuses on the image of the Israeli-Palestinian conflict in the Czech media, specifically on the presence of bias in news coverage. The thesis examines what, if any, elements of media bias are present in Czech media coverage of the Israeli-Palestinian conflict. The theoretical part of the thesis describes bias and related concepts, and then discusses the history of the Israeli-Palestinian conflict, including a closer look at Czech- Israeli and Czech-Palestinian relations. The thesis then presents selected foreign and Czech research that examines the media portrayal of the Israeli-Palestinian conflict. As a method, the thesis uses quantitative content analysis and analyses news articles published in the five most read online media during Israel-Palestine crisis in May 2021. The analysis focuses on the presence of contextual information about the conflict, the labelling of actions, actors and territories, and the way in which victims are reported. The results show the picture of the conflict presented by the Czech media is incomplete and distorted from different perspectives. However, the results do not show that the coverage is clearly biased in favour of (or against) the Israeli or Palestinian side.

Reaction of retail investors to financial market movements and sentiment changes
Hromčík, Jakub ; Schwarz, Jiří (advisor) ; Petrásek, Lukáš (referee)
This bachelor thesis investigates two areas. First, we study the impact of sociodemographic attributes on retail ivnestors following robo-advice in the choices of ready-made portfolios of passive ETFs with unique risk levels by employing a logistic regression model. Second, we investigate the impact of sociodemographic attributes on retail investors' trading volume adjustments in periods of high expected market volatility as proxied by the VIX index, for which we employ panel data regression methods over 18 consecutive months during a relatively stable period from January 1st 2021 to the end of 2022. We find, in agreement with reasearch on human financial advice, that women are more likely than men to follow risk level recommended by a robo-advisor, while being a man is associated with assuming more risk than recommended. Due to model assumption issues, our results are rather inconclusive in whether men tend to react differently to periods of high expected market volatility.

Bias of the Administrative Officials
Nová, Anna ; Vedral, Josef (advisor) ; Svoboda, Petr (referee)
Bias of the Administrative Officials Abstract The subject of this thesis is an analysis of the bias of public officials, which is regulated in Section 14 of Act No. 500/2004 Coll., the Administrative Procedure Code, as amended, with a primary focus on the practical aspects of the application of the institute. Special focus is also placed on the phenomenon of so-called systemic bias, which receives considerable attention from both the professional community and the general public. The thesis also examines the development of the position of the Constitutional Court and the Supreme Administrative Court's jurisprudence on the subject in the last two decades. The thesis is divided into four main chapters, which are further divided into subchapters, with selected subchapters further divided into sections. The first chapter analyses the fundamental principles of the institute of exclusion from hearing and decision-making and reviews the most significant milestones of administrative procedure codification, with a focus on the regulation of the institute of bias. The second chapter presents current legal regulation of bias in the Administrative Procedure Code as well as in special statutes and lays the theoretical groundwork necessary for a deeper insight into the issue. The third chapter focuses on the phenomenon...

The media image of the second round of the presidential election on television
Tomková, Aneta ; Chrenčík, Roman (advisor) ; Jirák, Jan (referee)
This master's thesis deals with the analysis of the media image of presidential candidates in the second round of presidential elections in the Czech Republic in January 2023. The aim of the thesis is to examine, through quantitative and qualitative content analysis of pre-election presidential debates, how individual candidates were presented on public and private television stations, and whether the principles of objectivity and impartiality were adhered to by the moderators. The first part of the thesis focuses on explaining key terms related to the subject matter, such as direct presidential election, media image, political communication, and the difference between public and private media. The presidential candidates and their political backgrounds are also introduced. The main part of the thesis is devoted to the analysis of the pre-election presidential debates. The quantitative analysis provides precise data on the extent of airtime allocated to each candidate, the number and nature of questions asked, and other relevant factors. The qualitative analysis allows for a deeper examination of the course of debates, the moderators' approach to individual candidates, and the identification of possible violations of the principles of objectivity and impartiality. The results of the analyses...

Bipartisanship of US journalism on the example of media coverage of the 2022 midterm election
Strnad, David ; Just, Petr (advisor) ; Charvát, Jakub (referee)
This bachelor's thesis deals with the relationship between American media and politics, particularly the partisan leaning of mainstream US media towards Republicans or Democrats. General media and political theories are introduced and then applied to a specific framework of the development of relationship between US media and political systems. It was necessary to include terms from political theory for completeness of the studied phenomenon which in itself is influenced by both media and politics. The thesis also draws on the hypothesis presented in Four Theories of the Press arguing that media reflect the social and therefore political system in which they operate. Hence, terms as media bias, agenda-setting or framing are accompanied by descriptions of a two-party system or the study of a general relationship between politics and the media. The thesis also offers overviews of the historical development of American politics and the media's relationship towards partisanship. The division of mainstream US media to two groups based on their appeal towards one of the parties is demonstrated not only by describing current analytical projects but also by own research. A quantitative content analysis with qualitative elements analyses and compares the thematic and genre representation of the online...
