Multivalued logic systems for technical applications
Turek, Vojtěch ; Druckmüller, Miloslav (referee) ; Martišek, Dalibor (advisor)
Velmi často je vyžadováno, aby automatizovaná zařízení byla jistým způsobem "inteligentní", tedy aby jejich řídicí systémy uměly emulovat rozhodovací proces. Tato diplomová práce poskytuje obecný formální popis vícehodnotových logických systémů schopných zmíněné emulace a jejich souvislost s teorií fuzzy množin. Jsou uvedeny způsoby vytváření matematických modelů založených na lingvistických datech. Dále se práce zabývá znalostními bázemi a jejich vlastnostmi. Součástí této práce je také počítačový program sloužící k tvorbě slovních modelů.

Analysis of Flow Distribution in Systems with Dense Tube Bundles
Babička Fialová, Dominika ; Dohnal, Miloslav (referee) ; Turek, Vojtěch (advisor)
Considering heat transfer equipment with dense tube bundles, it is essential to ensure as uniform a fluid distribution into the tubes as possible in order to prevent various operating problems. This bachelor’s thesis therefore focuses on tube-side flow analysis in such equipment. CFD simulations were carried out using a diverse set of flow systems with outflow into a constant-pressure environment. The respective tube bundle geometries differed in densities and sizes, arrangements of the tubes, and tube diameters. Air was used as the working fluid in the majority of the cases, however, some of the simulations were also carried out with water. Data obtained from evaluations in the fluid flow modelling software ANSYS Fluent were further analysed and the influence of the mentioned differentiating parameters on flow distribution non-uniformity and pressure drop was investigated. According to the regression model, the dependence of flow distribution non-uniformity on density and size of the bundle and on mass flow rate per unit outflow area cannot be rejected with the standard significance level. As for pressure drop, the only parameter that was not rejected was mass flow rate per unit outflow area.

Nonconventional Utilisation of Wind Energy
Zajíc, Josef ; Turek, Vojtěch (referee) ; Jícha, Jaroslav (advisor)
The thesis considers utilization of the wind energy as source of energy for the production of hydrogen. In the first part, there is described the types of wind engine specialized especially on screw wind engines and their construction. After that follows the description of dilemmas usage of electric energy addicted in time and with it connected problems with accumulation elektricity by the help of various methods. The final part of the thesis is than addicted to statistic evaluation of wind conditions, description and suggestion of the equipment hydrogen management.

Waste treatment in the Czech Republic
Janík, Prokop ; Turek, Vojtěch (referee) ; Bělohradský, Petr (advisor)
This bachelor thesis deals with the waste management in the Czech Republic and the possibilities how these wastes can be processed. In present period the waste production is tightly connected with the running of society. Waste and all the problems associated with their production and processing are delicate issue of present period. This is linked to technology developments and environmental quality in this field. Wastes are generated in both production and consumption of each product and conceal large quantity of raw materials and energy. Therefore, the biggest problem lies in finding the way in which energy and these raw materials are recovered and reused.

Waste Incineration II: Flue Gas Cleaning Equipment
Albrecht, Jan ; Juřena, Tomáš (referee) ; Turek, Vojtěch (advisor)
Description of the thermal treatment methods dealing with wastes is a major concern of the present study. Emphasis is placed on equipment and methods for purification of waste gases created in the process of thermal destruction. Considering that the efficiency of flue gas treatment is dependent not only on the activity of flue gas equipment elimination, but is completely dependent on a whole unit of operating incinerators, we can not focus exclusively on the block of flue gas treatment. Therefore, in the study there are given a description and drawings of equipment for thermal processing of waste. First part of this thesis addresses the koncept the concept of "waste", its definition, classification and possibilities for treatment or recovery. The whole thesis is also written with emphasis on current legislation relating to waste and thermal processing.

Utilisation of recycling machines in complex approach to waste treatment
Vlček, Zdeněk ; Turek, Vojtěch (referee) ; Bělohradský, Petr (advisor)
This bachelor thesis deals with a comprehensive approach to address the waste management system with the use of recycling machines. The work is divided into five chapters. The first chapter deals with waste such as ecological and economic problems. The second chapter examines the basic types of waste recycling. The third chapter concerns the legislation related to the management of waste. The fourth chapter contains a comparison of waste management and other EU countries. The last chapter contains the selected types of machines used in recycling.
