Morphology of genal caeca in selected trilobites from the Barrandian area
Vyhnánková, Iva ; Fatka, Oldřich (advisor) ; Laibl, Lukáš (referee)
The term "genal caeca" refers to branching and anastomosing ridges developed with varying intensity on free and fixed cheeks and preglabellar field in many trilobites, including the trilobites from Barrandian area of the Czech Republic. This diploma thesis presents the first detailed study of the morphology of genal caeca preserved on cephalons of Cambrian trilobite genera Ptychoparia Hawle & Corda, 1847, Mikaparia Kordule, 2006 and Conocoryphe Hawle & Corda, 1847 from Příbram-Jince and Skryje-Týřovice basins of the Barrandian area. Based on a detailed morphological description and measurements, separate fields of genal caeca occurrence were defined and frequency of their preservation on the studied specimens was compared. The variability of the number of ridges in each field and the frequency of their preservation do not show any convincing connection with cranidial size of the specimens or the locality. Keywords: trilobites, Barrandian area, genal caeca

Digital painting as a specific area of computer graphics
Vyhnánková, Iva ; Jeřábek, Tomáš (advisor) ; Štípek, Jiří (referee)
TITLE: Digital painting as a specific area of computer graphics AUTHOR: Iva Vyhnánková DEPARTMENT: Department of Information Technology and Education SUPERVISOR: Mgr. Tomáš Jeřábek ABSTRACT: Digital painting brings new possibilities to the field of arts. These possibilities consist not only of general advantages of software usage such as undo and easy modifications, but also of number of new tools, which can simulate traditional media to a certain degree. The work deals with digital painting in the context of its characteristic features, advantages and disadvantages as compared to traditional painting, and application, followed by the area of hardware and software. The practical part describes selected methods of not only simulating traditional techniques, but also of software tools application for specific painting techniques which traditional painting does not enable. KEYWORDS: digital painting, computer art, graphic software, painting, drawing
