Model
Hládeková, Katarína ; Mazanec, Martin (referee) ; Zahoranský, Dušan (referee) ; Fajnor, Richard (advisor)
The dissertation thesis studies the extension of the context of the term model as a means of interpretation for Czech and Slovak post-conceptual works of art. Based on result of a historical excursion into the history of painting, sculpture and architecture, the thesis offers a new typology of a model which is exemplified on particular work of art of Czech and Slovak post-conceptual era in the first two decades of the 21st century. The historical part of the thesis concludes the following: model in the art is an emancipated form originating from different academic as well as layman discourse; emancipated model has a methaphorical layer and thus it reflects wide historical, cultural and social relations. The categories proposed include: a linear model, a physical model, a cognitive model and an immersive model. The linear model encompases the sketch themes and so-called visualization metaphors (graphs, charts, schemes, etc) and originates as a reaction to information saturation and complicated networks. The physical model is a form to architecture and hobby modelling, it is characterised by a simple, „sketchy“ structure reacting to social themes and individual and collective memory. The cognitive model points to the cognitive turn of the society, it evaluates the materialisation of mental space and explains the emancipated model as an open category. Finally, the immersive model interprets the medium of exhibition as a model form which is articulated by and artisitic manifesto or an architectural interference. Another form of immersion that is being discussed in the chapter about immersive models, is a photographic or 3 D computer illusion as a reaction to society‘s virtualisation. Simultaneously to theoretical-historical research, an artistic research was taking place which became the basis for the creation of different categories and typologies of model. Each proposed category thus includes a so-called author‘s note reflecting the practical part of the dissertation thesis.

A design of a portion of a prototype of a new attendance system
Florians, Patrik ; Lipták, Ľuboš (referee) ; Neuwirth, Bernard (advisor)
Topic of this thesis discusses a proposed implementation of a part of a newly developed attendance system’s prototype for a company Global IT Center s.r.o. Theoretical section of the thesis includes various methods based on which an analysis of a current state and a proposal of a solution, which are located in later sections of this document have been formulated. An attendance system typically consists of multiple key components, however this thesis’ content includes only an analysis and a proposed implementation of a software part of the system – an attendance application. An analysis of a current state part includes a detailed analysis of a solution currently implemented in the company. The last part of this thesis – proposed solution includes a description of proposed implementation, which was implemented and tested using multiple technologically diverse environments.

Alternative Ontology: topological Imagination and Topological Materialism
Mrva, Jozef ; Csefalvay,, András (referee) ; Kořínek,, David (referee) ; Cenek, Filip (advisor)
The dissertation Alternative Ontology, subtitled Topological Imagination and Topological Materialism, focuses on the analysis of spatial phenomena and space in the intentions of the mathematical discipline of topology, which is interested in spaces from the point of view of set theory. My goal is to present topology as a tool not only for contemporary philosophy, but also for artistic creation. For the purpose of the dissertation, I formulate two concepts: Topological imagination and Topological materialism. Topological imagination is a tool and method for creating and thinking with the consciousness of space as a dynamic structure, which is not bound only by fixed laws of geometry. This method originated as the name of my long-term artistic practice, which is largely based on the study of space, topology, knot theory and the search for ways of their application in artistic and theoretical work. I propose Topological materialism as a concept that combines the thinking of networks and multi-dimensional spaces with the philosophical currents of the materialist tradition, especially the New Materialism. My basic thesis is that these cannot be perceived separately. Materialism cannot be thought without its spatial dimension, and topology without anchoring in the material world becomes a mere abstraction. The second part of the dissertation is devoted to the analysis of specific spaces: the space we inhabit, which I call phenomenological, infrastructure, logistics space, information space and the space of capital. In addition to individual analyzes, I also focus on their intersections, connections and joint operation.

Discrete Graph State Application Driver
Melkus, Josef ; Doležal, Jan (referee) ; Smrž, Pavel (advisor)
The aim of this work is to create a framework for integration testing of C++ systems based on their state diagrams. One part of the framework is a library defining the creation and transitions of a state diagram. Another part is an interface working on this library, that records state transitions in a run of a system. Records are then compared with an etalon. Etalon is the run of the system, that we consider as correct for a given set of inputs. The last part is an application for comparing state transitions and a script for test automation. The created system was tested within a partner company.

Web Application for Creation of Public Transport Maps
Lazúr, Juraj ; Škarvada, Libor (referee) ; Hynek, Jiří (advisor)
With the growing population of urban agglomerations, we can see an increasing frequency of traffic, which leads to traffic problems such as traffic jams. The most often solution of local governments is create a functioning system of public transport. However, this creates increased demands of passengers on clear, easy-to-understand and accurate information about these systems. The aim of this work is to simplify the process of creating maps, schemes of public transport lines. The purpose of the proposed application is to provide a wider group of users a clear and easy-to-use tool for creating interactive public transport maps that can be integrated into the websites of cities and municipalities. The outputs of the application should primarily serve to better passengers orientation in public transport systems, to shorten the time of travel by public transport.

The Use of Monetary Policy in the Simulator of Economic Instruments
PŘIBYL, Matěj
This thesis describes monetary policy and the use of its instruments in the modern economy. Monetary policy is a set of tools used by a nation's central bank to control the overall money supply and promote economic growth and employ strategies. The tools used and described in this thesis are for example, open market operations, discount rate and reserve requirements. These tools are used as a solution to random events that happen in a nation's economy. All these events are contained in a script which describes and suggests correct economic instruments to use. The main objective of this thesis is implementing the script into a diagram. The diagram also contains various choices and options to resolve events contained in this diagram. For example, rising inflation is dealt with by increasing interest rates. The output of the thesis will help banks to resolve various economic events and can also be used as a tool to educate students in economy oriented schools.

(Mis)use of graphical representation in annual reports of companies
CZERWENKOVÁ, Michala
This theses conducts an analysis of graphical representation in annual reports from year 2020 of leading companies from the Czech republic and companies listed on the Prague Stock Exchange. Annual reports are turned into attractive documents due to graphs and diagrams. A graph can represent a large amount of data and provides information about trends. Companies might manage their public representation through graphical representation so graphs are considered as tools of impression management. An example of tools of impression management is a graphical measurement distortion which is measured with indexes GDI (Graph Discrepancy Index) and RGD (Re-lative Graph Discepancy). The main cause of graph discrepancies are broken axes, such as non-zero axes, wrong scales and not displayed axes. Other very frequently applied tool is manipulation with time series through reversed time series and lenght of graphed time series.
