Democratic Party's Foreign Policy Voting: A Network Analysis
Mulica, David Robert ; Pondělíček, Jiří (advisor) ; Raška, Francis (referee)
This paper analyzes the voting behavior of Democratic Party members in the 117th Congress. Specifically, it examines roll call votes related to U.S. foreign policy. Namely, it examines votes on funding allocations for the two major policy departments of the executive branch - the Department of State and the Department of Defense, votes on resolutions, and other legislative actions in which Congress has jurisdiction over U.S. foreign policy. More particularly, this study is interested in the voting behavior of members of the so-called "Congressional Progressive Caucus" (CPC), one of the ideological caucuses in the U.S. Congress that has been gaining political strength, especially in recent years. The aim of the study is to show whether the "Progressive Caucus" has developed to be a political force that is already showing tendencies to vote differently from the rest of the Democratic Party, or which specific members of Congress are potentially in positions to mediate between the "CPC" and the rest of the party on foreign policy issues. The study uses the social network analysis methodology to process and project data on the voting patterns of individual members of Congress.

Digital Discourse Analysis of Posthumanism in Open Access Academia
Sen, Shivam ; Hájek, Martin (advisor) ; Sedláček, Jakub (referee)
Digital Discourse Analysis of Posthumanism in Open Access Academia Abstract In light of Human actions leading to an earth wide ecological breakdown it is importance to reflect upon the construction of the notion of 'Human' and how people's ideas of 'their being' is evolving and changing. At the same time, there has been a recent emergence of the term 'Posthuman' in academic literature. In a very general form, the term is implying something that is after 'human'. However, due to its newness it is yet ambiguous. Thus, this paper conducts a digital discourse analysis to identify the different senses of the term as used in open access academia, investigates the other important objects in the discursive sphere and describe the power configuration in the discursive sphere. Findings suggests three major senses of the term, (1) 'Posthuman processes'. (2) 'Posthuman beings' and (3) 'Posthuman perspectives'. Salience of 'novel socio- technical processes', 'human enhancement technologies' and 'new perspectives of beings' is found in the discursive sphere. Further, influential or powerful authors and ideas in the sphere are also identified.

Detection of Malware Communication in Network Flows
Korvas, Václav ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
This thesis deals with the issue of network communication of malicious code, methods of their analysis and especially the comparison of accuracy of different machine learning algorithms among themselves. The paper presents a comparison of the accuracy of different machine learning algorithms, both on test data and when used in real life. Accuracy, F1-score and false positive rate were used as metrics to evaluate the results. On the test data, the Random Forest and XGBoost algorithms were found to be the most accurate, achieving 99.2% accuracy with a rate of false positivity of 0.6%. In real-life experiments, approximately 9% of flows were incorrectly detected and classified as malware. When the computer was compromised, the rate of flows classified as malware increased to 18%, and several indicators of compromise were captured and confirmed the infection of the computer.

Analysis of horizontal transfer of genetic components using static network analysis
Labanava, Anastasiya ; Jurečková, Kateřina (referee) ; Schwarzerová, Jana (advisor)
The bachelor's thesis focuses on the issue of horizontal genetic elements transfer between bacteria of different strains and the software analysis implementation that enables horizontally transferred genes identification. The packages and tools used were tested on a dataset of bacterial genomes from several strains. The thesis’ theoretical part provides a detailed description of the genetic components transfer between bacteria and describes modern laboratory techniques that enable genome sequencing in various ways. In the practical part, the thesis deals with the preprocessing of genomic files to obtain suitable data for annotation. To detect the horizontal transfer of genetic elements between bacteria, a script is introduced, which organizes annotated bacteria to tables and searches for the same genes in their genomes that, under theoretical assumptions, were horizontally transferred. Furthermore, the gene transfer is visualized using tools that graphically represent phylogenetic relations between bacteria. In the final step, bacterial genomes are connected into networks, and based on their static analysis, a discussion is conducted on the results accuracy and the success of the proposed analysis.

The Belt and Road - Is China moving towards the centre of international trade? Assessment of impact on Balkans and Central Europe using network and gravity analysis
Reinštein, Jakub ; Semerák, Vilém (advisor) ; Komárek, Luboš (referee)
The Belt and Road Initiative (BRI) is a potentially world-changing Chinese economic and geopolitical strategy. In this thesis Gravity Model of Trade (GMT) and Network analysis are employed to assess the relative position of China in the International Trade Network (ITN), the overall impact of BRI, and its effect on countries in Central Eastern Europe and Western Balkans grouped in 17+1 mechanism. The results from Network analysis indicate that since the 1990s China is gradually moving towards the center of ITN. Subnetwork of BRI countries also exhibits higher cohesion and resilience to external shocks than ITN. GMT identified BRI as a significant and positive factor influencing exports, however in case of 17+1 mechanism countries the results are not robust. GMT was also successfully experimentally augmented with Network analysis variables demonstrating its possible enhancements and showing the path for further research. JEL Classification C23, C51, E27, F14 Keywords Gravity Model of Trade, Network Analysis, Belt and Road Initiative, 17+1 Mechanism Title The Belt and Road - Is China moving towards the center of international trade? Assessment of impact on Balkans and Central Europe using network and gravity analysis

Comparison and evaluation of mathematical methods in proceedings
ŽÁKOVÁ, Jana
In the preamble of the report, there are briefly described the basic notions of network analysis (the project and the network graph). Special attention is applied to the deterministic methods (Critical Path Method, Metra Potential Method) and their calculation as well as stochastic method (Program Evaluation and Review Technique, Graphical Evaluation and Review Technique), which are narrowly analyzed in the next chapter of the final report. The last two chapters of this part of the report are focused on the possibilities of simulation at proceedings projects and the software as a fundamental asset for planning and proceedings projects. The second part, which is mainly oriented to the practical points of problem, proposes the answer to stochastic and deterministic project at the application of the simulation technique by means of selected software.

Evaluation of the status and changes the availability of the primary health care of Czechia in GIS
Hořínek, Jan ; Štych, Přemysl (advisor) ; Brůha, Lukáš (referee)
This work is focused on evaluation the status and changes in the availability of primary health care in the Czech Republic. Primary health care in this case is divided into four groups according to specialty and surveyed the availability of the population from the whole republic to these doctors and at the same time the validity of the law which sets the availability of primary health care within 35 minutes. In the first part, individual theoretical parts, which are related to the topic and content of the work, are analysed. The next section describes the collection of used data. Another methodical part deals with data editing and processing. The last part contains the results and the evaluation which are illustrated in graphs as well as described. The graphical output is composed of maps (attachment) that show the local availability of the population to primary health care. The results provide not only the current state of primary health care, but also some estimates, how local availability can evolve over the coming years. The overall results are summarized in the conclusion. Keywords: primary health care, accessibility, network analysis, road network, GIS
