Evolutionary significance of visual traits of flowers and their influence on the pollinator constancy
Haveldová, Alice ; Štenc, Jakub (advisor) ; Klečka, Jan (referee)
Flower constancy is a behavior in which the pollinator visits flowers of the same plant species in a sequence more than would correspond to its preference for the given plant. This behavior is advantageous for plants because it can ensure efficient intraspecific pollen transfer which has a positive effect on their biological fitness. More efficient pollen transfer can lead to the selection of (visual and olfactory) flower traits that encourage flower constancy of pollinators. The main visual floral traits that affect constancy include colour, pattern, shape and size. However, these traits are of different importance for pollinators when they are deciding which flower to visit, and therefore their effect on flower constancy varies. The degree of flower constancy also differs between the functional groups of pollinators. Flower constancy is generally low in vertebrates, but insects and especially representatives of the order Hymenoptera are often flower constant.

Influence of external and internal factors on senescent changes of human face
Žigová, Dominika ; Velemínská, Jana (advisor) ; Kožejová Jaklová, Lenka (referee)
Aging is responsible for characteristic human facial changes. The purpose of this thesis is to identify and discuss possible factors that affect facial aging, which involves bone remodelling caused by progressive resorption of craniofacial bones. During the life, muscles become weaker as a result of muscle aging and activity, which leads to atrophy. In addition, their attachment to bones changes because of a decline in bone mass. Skin elasticity reduces with age, thus wrinkles are formed, skin colour changes and blood flow is impaired. Sun exposure is one of the extrinsic factors that have a significant effect on the facial senescent changes as it daily influences human skin by decreasing skin water content and impairing structures of collagen, elastin, and vessels. Smoking causes ischemia and wrinkles. Chronic skin diseases appear due to alcohol abuse, increased stress and air pollution. Sleep deficiency and low relative humidity environment contribute to skin dehydration and dryness. Skin can be protected and maintained youthful for longer by having a healthy diet. Aside from extrinsic factors, senescent facial changes are also influenced by various genes, a hormonal change, and bone remodelling. Nowadays, people age more slowly because of medical progress, better health care, new findings, and...

BRNO – NEW SOUTH CENTRE LOCATION – POŘÍČÍ, BRIDGES TRINITY, THE AREA OF COMMUNICATION AND SOCIAL INTEGRATION, MULTIFUNCTIONAL OBJECT AND SPACE
Prokešová, Markéta ; Bindr, Tomáš (referee) ; Kiszka, Josef (advisor)
This bachelor thesis deals with understanding the place, its analysis, reflections on future development and then the design of a new part of the city, buildings, renovations and modifications. It's necessary to think about social and cultural functions to ensure a comfortable life of the population, social interaction in the already existing community and support for incoming residents in the new part of the city. The semester work follows the proposal of revitalization of Svratka by prof. Ing. arch. Ivan Ruller, develops its potential and considers further expansion

Utilisation of shape analysis methods for object classification in medical images
Karela, Jiří ; Odstrčilík, Jan (referee) ; Chmelík, Jiří (advisor)
Bachelor thesis deals with problems of shape analysis. It describes some procedures and methods related to this kind of analysis. The thesis is divided into theoretical part, practical part and conclusion. In the theoretical part we describe in greater detail some methods, with the help of which the practical part was solved. But other theories related to the topic are also described. The practical part then follows the given theory and solves the problem of shape analysis due to the knowledge gained in the theory. The algorithm is tested on medical data from CT of vertebrae. The conclusion serves as a summary and evaluation of the shape analysis solution. It also serves as a reflection on the realization of our method, ie how our solution and result could be improved.

Relationship between testosterone and man facial morphology
Šefčíková, Alexandra ; Třebický, Vít (advisor) ; Pokorný, Šimon (referee)
Sex hormones influence the overall development of the individual, its development of the metabolic processes, and the distribution of the adipose and muscle tissue, the anatomy of the skeleton, the features of the face and the general appearance of the feminine and masculine phenotype. The morphological differences between men and women can be observed and studied already at the very young age. It is estimated that these differences relate to the distinct levels of the prenatal sex hormones. The occurring changes on face are continuously increasing during the period of adolescence yet, the peak of their development is spotted at puberty. In men's case, the level of testosterone is high enough to boost the growth of the secondary sex differences and the masculine features. In comparison with women, the face of men becomes more robust where the prominence of the supraciliary arch, nose and jowl is extended. The sex dimorphism of the face is one of the most significant signs of the intrasexual and intersexual selection. Key words: Morphology, face, sexual dimorphism, hormones, testosterone

Výrazové prvky současné architektury
Kokolia Křížová, Iveta
In the recent years, the process of architectural design has been evolving in a number of different ways, as it has always been the case. The goal, however, remains the same - to design a quality architecture. New forms and architectural elements have also emerged with the advent of modern technologies. What are the defined facts that enter into design and reveal the boundary between high-quality architecture and mere „building“? What signs could define the current period?

Multiplication of shape as a means of constructing reality
Málková, Helena ; Magidová, Markéta (advisor) ; Čech, Viktor (referee)
Málková, H.: Multiplication of shape as a means of constructing reality. [Diplom thesis] Prague 2017 - Charles University, Faculty of Education, Department of Art Education, 123 pages. The diploma thesis focuses on the theme of creation of systems, structures and constructions in visual reality. The theoretical part is aimed at the possibilities of multiplication, its growth into space or a plane, while regarding creation of plastic arts by selected artists from the field of fine arts. The practical part introduces author's conception of the topic by the means of photographic medium. Structure is a crucial phenomena in possible understanding of visual reality. It has prerequisites for development of transcendental thinking. We can discover it throughout the whole universe as its unifying element. The findings from the theoretical part are used as basis for didactic activities. The didactic part presents the realized art assignments, which are a part of the implementation of the research. The thesis brings findings and conclusions within the framework of the results of creation and teaching of the topic of spatial composition of multiplied form within a coherent object. KEY WORDS: construction, structure, movement, shape, space, material variability, racionality, photography, object creation,...

Quality Check of Text in Forms
Moravec, Zbyněk ; Juránek, Roman (referee) ; Zemčík, Pavel (advisor)
Purpose of this thesis is the quality check of correct button text display on photographed monitors. These photographs contain a variety of image distortions which complicates the following image graphic element recognition. This paper outlines several possibilities to detect buttons on forms and further elaborates on the implemented detection based on contour shapes description. After buttons are found, their defects are detected subsequently. Additionally, this thesis describes an automatic identification of picture with the highest quality for documentation purposes.
