Evaluation of dimensional and shape accuracy of components made of plastic
Tuza, Marek ; Dobrocký, David (referee) ; Sedlák, Josef (advisor)
The aim of this thesis is to evaluate the dimensional and shape accuracy of components made of plastic. A total of 10 samples, produced by two types of production, extrusion and 3D printing using the FFF method, were used for this purpose. The semi-finished products were milled after production, which resulted in samples of the required dimensions. The samples were milled on one side without cooling emulsion and on the other side with cooling emulsion, which significantly affected the resulting shape accuracy values. Thus, a total of 20 surfaces were evaluated. Two parameters were selected to evaluate the dimensions, namely distance and parallelism. When measuring the shapes, 11 parameters were evaluated using a 2D roughness profile and a 3D surface texture. One of the most used parameters that was evaluated when measuring shapes was the arithmetic mean deviation of the roughness profile, which is denoted as Ra. The research found that the highest accuracies were measured for the material PA produced by 3D printing and milled with a cooling emulsion. At the end of the practical part, the author also makes recommendations regarding the practical use of materials.

Shape Measurement of Loaded Tyre
Hlavatý, Jiří ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This thesis is focused on measuring the shape of loaded tire and finding dependencies between inner tire pressure, load and the influence of these parameters on the resulting shape of the tire. Data for these dependencies were obtained by using a constructed measuring stand and 3D optical technology. Found dependencies describe the change in shape of the tire in specific mathematical functions, and served the creation of a parametric model of the tire. The main finding of this thesis is that the tire is actually behaves according to dependencies described by varying degrees of polynomial function.

Change in the perception of feminism in Czech literary magazines in the 2010s
Součková, Alžběta ; Čeňková, Jana (advisor) ; Osvaldová, Barbora (referee)
This thesis examines the change in the perception of feminism on the pages of three Czech literary magazines between 2011 and 2020, i.e. in the 2010s. The thesis includes a brief presentation of the historical development of the women's movement in a global perspective and in the context of the Czech territory, as well as the theoretical definition of the concepts of feminism and gender. An important part of the thesis is also a presentation of the current perception of feminism in Czech society and the events that have shaped the image of feminism in the Czech Republic since the early 1990s. Furthermore, the thesis reflects on contemporary Czech literature and its relationship to feminism, including personalities occupying strong points of view on different poles. The whole theoretical background is then used in the analysis of three particular literary journals: A2, Host and Tvar. In these literary magazines, texts dealing with feminist topics are captured through content analysis. Subsequently, these texts are further processed and categorized. The aim of the analysis is to provide the most possible up-to-date image of the perception and presentation of feminism on the Czech literary scene, but also to find out, whether and to what extent the literary magazines deal with the topic. The analysis...

The phenomenon of home and its importance for education
SOLDÁTOVÁ, Marta
The aim of this diploma thesis is to describe the importance and significance of the home phenomenon in terms of the education of the human individual. The work captures the development of views on this issue from the perspective of ancient, Czech and world philosophers. The philosophy of the home will be further discussed from the point of view of Patočka and Lévinas. The work will also try to offer some answers to some current questions of society, which relate to the home and its loss. The issue of education and care for the soul are also discussed.

Abstract Tendencies in Czech Art throughout the 1970s and 1980s.
LAZÁRKOVÁ, Simona
The diploma thesis named ´Abstract Tendencies in Czech Art in the 1970s and 80s´ is processed in both, a theoretical and a creative, practical parts. The theoretical part presents abstract tendencies in Czech art during the 1970s and 80s representing the work of artists creating pieces of a ball and a geometrical shape of a circle in both, surface as well as spacial creation. The works of Václav Boštík, Stanislav Kolíbal, Hugo Demartini, Vladimír Škoda and Woody Vasulka are presented and emphasized. The practical part is presented in the form of a graphic creation including a circular theme with a subsequent area solution in gypsum. Everything is accompanied by drawing studies, graphic examinations and gypsum castings of circular objects.

Live Architecture. Organic motifs of modern architecture as inspiration for free graphic creation.
DRÁBKOVÁ, Veronika
The diploma thesis "Organic architerue. Live Architecture. Organic motives of modern architecture as inspiration for free form graphic creation" consists of teorethical and practical part. The theoretical part consists of development of the architecture and in this part is specific focus on the organic architecture. It focuses on the most important representatives of this direction. The thesis highlitghts one of the most important person of nowadays, she is originaly of Irac and her name is Zaha Hadid. This chapter describes her life, cooperation and influences that influenced her work. In the end of the theoretical part, there are selected awards which she has received in her life. The practical part contains a set of inspirational photos and preparatory drawing sketches, which there are supporting work for results graphic lists isnpired by the work of Zaha Hadid and another organic motives. The final realization of the practical part is the author's book, which was inspired by organic architecture.

Relating to another person in the ethics of E. Levinas
VOLFOVÁ, Adéla
The thesis is theoretically arranged and comprises two main chapters. It deals with an ethical concept of the relationship towards the Other person that is represented by a French philosopher of 20th century Emmanuel Levinas. The relationship between the Self and the Other is developed, in which the other person is always the primordial centre of my interest. The primary feature of Levinas´ ethics is to show it like the first philosophy. It is particular for him to understand metaphysics in a purely ethical concept. At Levinas, there is an event of a turn in ethics, when the current ontology, which is focused on a theoretical knowledge, is substituted by metaphysics. Morality is acknowledged as an essence of ethical relationship with the other person. This interpersonal relationship is always an asymmetric relationship and fundamentally ethical. Levinas´ ethics is the ethics of responsibility for the Other, in which is possible to approach the Other. The ethics deals with a concept of transcendence, Infinity, exteriority and interiority.

Problematika chovu holandského králíka pro výstavní účely
MASOPUSTOVÁ, Vladimíra
The bachelor's thesis deals with the issue of breeding Dutch rabbits in pet breeding for exhibition purposes, which annually participates in about 5 to 7 exhibitions of nationwide and foreign character. In literature search are described the basic concepts and theoretically the issue of breeding using the professional literature. Own part of the bachelor's thesis contains the characteristics of breeding and the number of completed exhibitions, a consecutive description of housing, feed rations, weaning and consesutive preparation of breeding animals for the exhibition. Furthermore, the evaluation of success for the year 2015-2019 is described and illustrated in terms of the number of total points obtained at the exhibition, the type, shape and exterior features of the drawing, which are given by the breed standard. The conclusion of the work is focused on the evaluation and comparison of results according to the obtained material for the past five years.
