Programming of the ELSM method for the advanced stability analysis of geotechnical structures
Štetiar, Juraj ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
This master's thesis addresses the issue of slope stability, which is a key task in the design of geotechnical structures. The study focuses on the Enhanced Limit Strength Method (ELSM), which leverages the advantages of the Finite Element Method (FEM) while allowing the control of the position and shape of the slip surface. ELSM is particularly advantageous for addressing the stability of embankments and aerial slopes of earth-filled water reservoirs. The objective of the thesis is to develop an algorithm for the ELSM method as an additional module for existing FEM solvers. The theoretical part of the thesis explains the principles of commonly used slope stability calculation methods, such as the Limit Equilibrium Method (LEM) and the Strength Reduction Method (SRM). Subsequently, the principles of the ELSM method (determining the factor of safety for the critical slip surface) are introduced, and the optimization algorithm Particle Swarm Optimization (PSO) is briefly described. In the practical section of the thesis, the programmed algorithm for slope stability calculation using the ELSM method with the utilization of the Particle Swarm Optimization (PSO) optimization module is explained. The correctness of the algorithm is verified, and a comparison with the SRM and LEM methods is conducted through three verification studies, including a simple homogeneous slope, a heterogeneous slope with a horizontal material interface, and a real case study assessing the external stability of the dam structure at the Vlachovice waterworks.

Algorithmization of social networking sites and its perception by adolescents
Hegedüš, Tomáš ; Švelch, Jaroslav (advisor) ; Reifová, Irena (referee)
The diploma thesis Algorithmization of social networks and its perception by adolescents deals with the issue of algorithms which lead to personalization of social networks. Their perception by children and adolescents is currently not sufficiently explored. In the theoretical part, I demonstrate how the current studies examine the perception of algorithms on a sample of the entire population, in the context of adolescents how they focus on social networks as a whole. Therefore, the ambition of this thesis is to research the intersection of these three spheres and its impact on adolescent's perception of algorithmisation of social networks. Through qualitative research using the method of semi-structured interviews, this thesis outlines trends that may prevail in this area. An analytical synthesis of knowledge also answers the questions of how adolescents are informed about the possibilities of influencing the selection and sorting of the content and whether they show interest in these possibilities. In the theoretical part, I introduce readers of this work to the issue of new media, how social media developed, including their convergence. Among the researched social networks are Facebook, Instagram and YouTube. To understand the comparison of reality and the statements of the respondents, in the...

Algorithmization of social media and its effects on online media
Zítko, Tomáš ; Kasík, Pavel (advisor) ; Jirků, Jan (referee)
The rise of social media has changed how growing numbers of internet users get their news. Unlike traditional media, there is no universal information for everyone on social networking sites. Instead, each user receives a personalized sample of posts picked for him by a filtering algorithm. The workings of those two types of information selection are the main topic of this paper. Based on the gatekeeping theory, I offer models of editorial and algorithmic news selection and their comparison. I also compare different values of human and algorithmic gatekeepers and introduce the concept of objectivity and its limits in both cases. In the second part of this thesis, I present qualitative research into the awareness of the Facebook algorithm. Using semi-structured interviews with seven Facebook users I explore a set of specific examples of how users view Facebook as an information source, how they understand its algorithmic nature, and how satisfied are they with it. The main aim of this theses is to investigate whether the users are aware if various limitations resulting from the news-filtering technology in general.

Algorithmization of social media and its effects on online media
Zítko, Tomáš ; Kasík, Pavel (advisor) ; Jirků, Jan (referee)
The thesis Algorithmization of social media and it's effects on online news consumption examines the transition of social networking sites from chonological display of posts to automatized system of relevance assignment. This assesment is realized through algorithmic filters, which uses predefined criteria and processes to assign relevance to individual posts. Main goal of this thisis is to define compare a theoretical model of mechanized selection with traditional editorial model, together with user understanding of Facebook algoritmization. The thesis combines a theoretical part, which presents the specifics of both models, with qualitative research with aims of the conceptualization of user's understanding of the algoritmized nature of Facebook. The theoretical section also integrates algoritmic filters with the current gatekeeping theory, compares news and algorithmic values and describes the basic biases, which may occur in the two models of information selection. The second part of the thesis explores the user understanding of Facebook algorithmization. The methodology is based on qualitative research with case study design through semi-structured interviews with seven Facebook users. Interview analysis is based on predefined body of subjects: general information, understanding of algorithmization and...

The Development of Algorithmic Thinking among the Pupils of Lower Secondary Schools
Fiala, Jan ; Vaňková, Petra (advisor) ; Novák, Jaroslav (referee)
The diploma thesis deals with the development of algorithmic thinking among the lower-secondary students as one of their digital competences. It is based on the principle of algorithmic thinking related to the concept of computational thinking and it searches for the ways how to develop it in pupils. The theoretical part is supported by Skinner's concept of programmed learning and with the help of gamification proposes the research based on the students' observation in one school year in which the competence is developed. The raised issue is solved by setting a complex set of teaching materials and learning activities (both in the digital environment and unplugged activities) and their partial transfer into the teaching to a virtual, algorithmic environment of the specially designed application called Prográmko. The goal of the thesis is the analysis of the possibilities of how to include the gamification and the programmed learning into the practice of the development of algorithmic thinking taught at the lower-secondary schools. The research also evaluates the applicability of the application Prográmko and the proposed set of materials provided with methodological guidelines in the practice.
