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.

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.

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.

Application of morphometric methods in anthropology
Pešek, Adam ; Eliášová, Hana (advisor) ; Šuláková, Hana (referee)
In last thirty years a new branch of comparative biology is growing rapidly, this branch is called the geometric morphometrics. Methods of geometrics morphometrics allow to gain and evaluate data about shape and size of studied object in 2D or 3D space. The character of input data divided methods used in geometric morphometric on method based on analysis of outlines and method based on analysis of landmarks. Many modern technologies like contact scanner, laser scanner or tps software are helping in data acquisition. The main conclusion of this bachelor work was exploring usability of methods of geometric morphometric in many cases in Anthropology. In many biological and mainly anthropological studies, geometric morphometric were applicated to compare shape variance and in studies of variability of shape. Common are studies of sexual dimorphism on human skeleton, ontogenetic developement of skeleton, disparity of sign on human skeleton among population and ethnicity or changes of these forms of structures in populations during time.

Paraphrase classical artwork - a didactic transformation and application of topics in art education
Košatová, Barbora ; Šmíd, Jan (advisor) ; Sedlák, Michal (referee)
IN ENGLISH This thesis has the character of theoretical studies on the topic paraphrase a classic work of art and its subsequent didactic applications for that grade school. It solves the problems of paraphrasing in the visual arts. It characterizes the aspects related to the topic, such as analysis and structure of a work of art. It focuses on the theory of shape as the basic building blocks of artwork and associated topics, which are: quotes, interpretation, image transformations and alterations. Art work is a continuation of a previous bachelor thesis, which dealt with the issue of land. It deals with the transformation of the original image resulting from the help of manipulation of individual shapes in the image, replacing the existing design to a new one. They are created in the form of the photographs from the area of pre-defined landscape Didactic section applies subject paraphrase the selected school and verifies and theoretical knowledge in practice. It depicts the topic paraphrase as a whole. The objective is to try and understand the basic principles that apply to paraphrase.

The variability of facial expressions in relation to age and sex: pilot study for monitoring the treatment of facial palsy.
Danková, Simona ; Velemínská, Jana (advisor) ; Schmidová, Kamila (referee)
This thesis deals with the analysis of 3D morphological changes and variability in the shape and form of facial expression during five specifically defined facial expressions (raising eyebrows, close both eyes, lips pursing, inflating both cheeks, smile). Changes in facial expression were evaluated in relation to sexual dimorphism and age category of probands using the methods of geometric morphometrics (Dense Correspondence Analysis, Paired Analysis, Principal Component Analysis, Shell-to-Shell Deviation) in program Morphome3cs and RapidForm. The analysis consisted of evaluating the surface of soft tissue changes that occur due to the contraction of facial muscles. Materials used for the analysis are 3D surface facial models of adult healthy people of the Czech nationality (63 women, 58 men) in the age interval 20-60 years. We considered methodology based on Paired Analysis to be more accurate, when we worked only with differences between the neutral expression and facial expression. By choosing a Paired Analysis, we prevented the morphological features of the face from being reflected into the results. Morphological features are a manifestation of sexual dimorphism or age factor as such, but they are not themselves the essence of facial expression. In this way, we analyzed the shape of the face after...
