Optimalization of Induction Furnace Operation in foundry Vsetín
Trachta, Jiří ; Nowak, Stanislav (referee) ; Lázničková, Ilona (advisor)
The aim of this work is optimalisation of induction furnace in foundry for company PROMET FOUNDRY a.s. The company has two induction furnances. There are installed as identical construction. They have 2 modes of operation. First mode is founding and second mode is mode, where is temperature in maintain mode. Only one induction furnance can work in the founding mode at a time though. Inducion furnances are in the single-phase connection and they cause unbalance in the distribution network. Near the foundry there is a small network area whitch it is operated by company Zásobování teplem Vsetín a.s. The consumption of electrical energy in foundry so big, that in the year 2009 was made elaborate for Zásobování teplem Vsetín a.s. It was write at Laboratoře diagnostiky výkonů (Laboratory of performance diagnostics), which is a part of Electrotechnic Department at Technical Univarsity of Ostrava. The ordered study was named “Verification of causes of increased reactive energy consumption during transition from electricity delivery to electricity consumption”. The conclusion of this assignment confirms that in distribution network in the Jiráskova area in Vsetín there is unbalance of electrical energy and there is high part of reactive power. The next conclusion is crucial to find the customer who made the unbalance and to set relevant remedy. The last step will be the identification whether such device can actually be effectively balanced. It was subsequently proved that the Promet Foundry was causing the unbalance and that balanced consumption would be reasonable. Promet Foundry thus addressed Autel a.s. company with an inquiry to make a study of removing the causes of the unbalance which is caused by current induction furnaces operation at a minimum possible cost, least possible influence on the performance and minimum construction changes concerning the building. In this thesis there will be some topics. The result of which will be introducing of used heating technology, introducing of company and of effective plant performance and subsequent suggestions of possible unbalance removal or reactive power decrease. Several ways which are being implemented in the industry in order to balance consumption will be described. A suitable balancing plant will be subsequently chosen and its parameters will be calculated.

The Tax Havens and Their Uses
Wilczková, Martina ; Nowak, Stanislav (referee) ; Kopřiva, Jan (advisor)
The Master's thesis is focused on tax optimalization through tax havens. The Master's thesis is divided into six parts. The first part generally outlines the problems of international tax optimalization. The next one defines concepts related to tax havens, use of tax havens and the fight against tax evasion. The third chapter concentrates on direct foreign investments, which are connected with holding companies. Information from this chapter is used in the following chapters. The practical part consists of two and shows the costs for establishment of a model subsidiary and the tax costs of the company for the first year of its running in chosen tax havens. These costs together with other information about chosen tax havens are analysed. Subsequently, a suitable location for the company in one of these destinations is suggested.

Formal description of board games
Nowak, Stanislav ; Štěpánek, Petr (advisor) ; Kunčar, Ondřej (referee)
The aim of thesis was to design a mathematical formalism that allows describing and exploring the properties of board games. The work benefits from the findings of automata theory and logic programming. First part of thesis deals with finite automata and their possible applications for the needs of board games. The result is an extension of finite-state automaton covering the specifics of board games called game automaton. Board games are a complex domain hight level tools should be used. Such a tools is a logical programming. Using logic programming was designed instrument that allows declarative descriptions of games, named gaming system. This declarative description is used as an framework for the implementation of interactive games. Linking the two worlds will be demonstrated by conversion of the gaming system to the game automaton.
