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.

Extension and renovation of communication network in the area of high school
Valný, Jakub ; Sedlák, Petr (referee) ; Novotný, Vít (advisor)
The bachelor's thesis deals with a proposal for the expansion and modernization of a computer network in the high school building. The analytical part of the work describes the current state of the computer network, the building itself and the requirements of the investor. The theoretical part of the thesis describes the information needed to develop the design itself. The design section describes my own project elaboration. The last part of this work is the economic evaluation of the proposal.

Company Computer Network Design
Ambroz, Vojtěch ; Jakub,, GERICH (referee) ; Ondrák, Viktor (advisor)
This bachelor's thesis proposes a computer network for a branch of a newly emerging local company dealing with information security. The first part of the work analyzes the current state of the computer network, building, hardware and software requirements and, last but not least, the requirements of the investor. The next part of the work contains general basic information about computer networks needed for designing the concept. This is then elaborated in the third part of the work. It contains specific cabling solutions, all selected devices, but also an economic evaluation of the entire concept.

New laboratory tasks of the KNX system
Welter, Martin ; Kunc, Josef (referee) ; Bátora, Branislav (advisor)
The bachelor's thesis deals with the design of laboratory tasks for the control of the KNX system electrical installation using devices from the company Hager and Berker. The first part discusses the characteristics of the KNX system, topological arrangement, ETS software, communication media. Furthermore, the remote control of KNX wiring is briefly discussed with subsequent visualization from various companies. The next part is devoted to getting acquainted with the devices that will be used for laboratory tasks with the subsequent creation of laboratory instructions. All functions have been programmed in ETS5 software. Finally, an overall evaluation is made.

Contemporary Educational Legitimation Ecology: positions, knowledge, and critique
Wirthová, Jitka ; Balon, Jan (advisor) ; Veselý, Arnošt (referee) ; Fučík, Petr (referee)
This dissertation focuses on the current Czech space of legitimation practices in education as a variable sphere of justification and critique of educational goals rooted in global transformations of educational institutions, autonomies of the nation states and transnational comparative data. Since the debate on educational reform (2004), the Czech legitimation educational ecology has been diversified by different types of knowledge and actors (state, non- profit, private sector). In this work, I argue that legitimation as a critical action is today, in various ways and processes (knowledge regimes, patterns of actorship) derived from traditional jurisdictions (state and professional structures) and moves to more flexible structures, which I call topologies. In jurisdictions, mostly passive audiences remain. New legitimation topologies connect values and data and, in many ways, replace dysfunctional state structures, using specific disconnections, but also question the public nature of negotiating educational goals. Based on relational ontology and sociological topological studies and through a qualitative relational analysis of legitimation practices in three fields (published normative documents, public debates and semi-structured interviews with state and non-state actors) I show in the period...

Lie groups and their physical applications
Kunz, Daniel ; Kureš, Miroslav (referee) ; Tomáš, Jiří (advisor)
In this thesis I describe construction of Lie group and Lie algebra and its following usage for physical problems. To be able to construct Lie groups and Lie algebras we need define basic terms such as topological manifold, tensor algebra and differential geometry. First part of my thesis is aimed on this topic. In second part I am dealing with construction of Lie groups and algebras. Furthermore, I am showing different properties of given structures. Next I am trying to show, that there exists some connection among Lie groups and Lie algebras. In last part of this thesis is used just for showing how this apparat can be used on physical problems. Best known usage is to find physical symmetries to establish conservation laws, all thanks to famous Noether theorem.

The effect of the environment on bacterial DNA topology and gene expression.
Mikesková, Klára ; Krásný, Libor (advisor) ; Večerek, Branislav (referee)
Biological processes in the cell are affected by DNA topology, i. e. by DNA structure and shape. An important topological parameter is the level of supercoiling - additional twisting of DNA is relieved by positive (twisting in the same direction as the helix turns) or negative (twisting in the opposite direction) supercoils. In this Thesis I review the role of supercoiling in gene expression regulation. I describe how supercoiling is involved in homeostatic mechanisms that control the transcriptional output from some genes. Environmental changes such as shifts in temperature, oxidative stress, extreme pH and antibiotics and other inhibitors affect the level of DNA supercoiling. DNA supercoiling then affects the expression of enzymes, which influence DNA topology, as well as some other genes/proteins. In summary, this Thesis describes how changes in the environment influence bacterial DNA topology and gene expression with a brief mention of this type of regulation in eukaryotes.

Variable Two-Way Loudspeaker Cabinet - Laboratory Tool
Rehák, Jan ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
The objective of this work is to build a two-way loudspeaker system that will enable changing loudspeaker topology in both vertical and horizontal axes and to suggest two laboratory tasks. The theoretical part of this work will briefly discuss loudspeaker crossovers. Then it will discuss how topology of loudspeakers in a loudspeaker system can affect its behavior at crossover frequency. Frequency characteristics of various loudspeaker baffles will be shown. On these, the effect of a baffle’s exterior on its behavior will be discussed. A two-way loudspeaker system will be designed. The construction process and drawings of each part are also included in this work. The finished product will be tested and, following from these tests, a conclusion will be drawn about the validity of the theoretical assumptions of its design. After that, appropriate parameters of a crossover for the two-way loudspeaker system will be chosen.
