Catalytic behaviour of ceramic catalytic materials
Schlosser, Radek ; Cihlář, Jaroslav (referee) ; Cihlář, Jaroslav (advisor)
In this bachelor’s thesis the methods of preparation of ceramic perovskite-like membranes for heterogenous catalysis and reformation reactions of carbohydrates were studied. The syntetic La-Ca-Fe-Ti-O type and commercial La-Ca-Fe-Co-O type powders were used. The properties such as phase purity, specific surface area and morphology of used powders were determined. Technology of processing included powder uniaxial pressing, membrane sintering and polishing their surface. Conditions for uniaxial pressing were optimized. The dependence of grain size and amount of titanium was determined.

Tvarované stromy v zahradní a krajinářské architektuře
Nguyen, Jakub
This study delas with historical development of tree shaping and its use in garden design and landscape architecture since ancient times till recent. Biological basis of tree shaping is discussed as well as tree charactericstic important for shaping and technologies used for establishing, maintenance and restoration of these vegetation components. Basic assortment of shaped trees available on European market is also listed. Model project, in which composition shaped trees are playing major role along with othe vegetation components, was designeed as a part of this study and executive and technical documentation describing of shaped vegetation in model object was prepare.

Design of a robotic cell for hydraulic pipes moulding
Bartošek, Jindřich ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
Předmětem této diplomové práce je návrh robotické buňky pro tvarování hydraulických trubek. Práce obsahuje analýzu technologie tvarování trubek a zdůvodnění potřeby automatizace celého procesu. Z návrhů jednotlivých konstrukčních uzlů byly vybrány nejvhodnější řešení a ty pak byly aplikovány při konstrukci buňky. Robotická buňka byla navržena s ohledem na bezpečnost provozu, funkčnost a jednoduchou ovladatelnost. Na závěr je vypracováno ekonomické zhodnocení projektu. K práci je přiložen návod pro ovládání, výkresová dokumentace, model buňky a výsledky simulace.

Povrchová úprava sedadel v prostředcích hromadné dopravy
Culka, Jiří
This thesis is focused on the evaluation of the physico-mechanical, chemical and visual characteristics of coatings to seats designated to public transport. Shaped seats and the test samples are made of beech lamellae. The characterictis are evaluated and compared between four surface finishes achieved values of individual laboratory tests and requirements according to standards. As the surface finishes was chosen polyurethane and water-borne paint.
