Surface casting defects
Rašek, Ondřej ; Pernica, Vítězslav (referee) ; Tomek, Ladislav (advisor)
Surface defects in casting include after decades of research on current problems of metal cast. They mean significant losses for foundries. Thesis includes a review of kinds of defects, their origins and their examinations, the effects on the mechanical properties and their machinability.

Special surface finish architectural concrete
Gajdoš, Jan ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
The aim of this work is to describe modern methods of finishing concrete with architectural division of the surfaces created in fresh and hardened state. In this work describes the various influences and their effects on the resulting surface such as concrete composition, method of storage or production and compaction of concrete. In the practical part of the thesis focuses on the technology of graphic concrete and its application to vertical monolithic wall.

Types of riding hall surfaces
CHALUPOVÁ, Aneta
Cílem práce bylo zpracovat přehled o informacích, zjištěných od chovatelů, o struktuře povrchů jednotlivých jízdáren pro koně. Dotazníkovým šetřením a osobní konzultací se zjišťovalo též uplatnění a spokojenost chovatelů s kvalitou povrchů jízdáren.Na základě výsledků dotazníkového šetření byly zpracovány informace o každém z jednotlivých povrchů jízdáren a přehled o kvalitě a oblíbenosti jednotlivých povrchů v oblasti Jihočeského kraje.

Vliv mytí na degradaci laku vozidla a jeho hodnocení
Duda, Stanislav
This thesis deals with the problematics of varnish degradation due to maintanance of a car or more precisely due to washing of a car bodywork and searching for a gentle washing of a car. The first section of this thesis discusses the creation of a protection layer of the car bodywork or types of varnishing, particular layers of varnish and additional products enhancing the qualities of car varnish. Second part of thesis analyses the measuring and evaluation of the state of varnish layers and uses the results for valuation of estetical and functional advantages and disadvantages. In third part we deal with description and categorisation of types and technologies of car washing. Fourth part focuses on experimentation and comparison of varnish degradation due to selected types of car washing using tests simulating real conditions of regular service. Particularly we evaluate portal washing units and hand washing. Consequently we subjectively and objectively analyse all the information and finaly we project this information to time and economical perspective.

Implied Volatility and Smile
Rojček, Jakub ; Pígl, Jan (advisor)
In this work author speaks a little in generic about financial derivatives. Then he derives the famous Black-Scholes formula using less precise mathematical apparatus. Afterwards, he will analyze a few volatility models and their applications for creating volatility surface, which is the main goal of both theoreticians and practitioners. As we will see, the theory is yet very deep but unconsolidated. Nevertheless, praxis has gained some nearly sufficient approaches.
