Information System Selection
Krejčí, Tomáš ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
My thesis contains description of the selection process of an information system for the company VAŠ hotel B & B Ltd., which runs VV hotel in Brno. The chosen information system aims to improve current processes which leads to increase the number of accommodated persons. The first part of this thesis describes theoretical background, which I implemented in analytical and practical part of this thesis. The following chapter describes the current situation. As a part of this thesis I did analysis of specified budget for the selection of the information system. The last chapter describes the selection of the information system. In this chapter I’ve specified system requirements and described the whole selection process. The end of this thesis, identifies benefits that comes with it, and this chapter also contains an economic evaluation of the entire proposal.

Variable geometry of intake and exhaust ports of Wankel engine
Krejčí, Tomáš ; Beran, Martin (referee) ; Zháňal, Lubor (advisor)
The purpose of this thesis is to design the key parameters of the high-powered Walkel engine and to design a chamber side on the base of computed parameters so that it enables variable change of the intake and exhaust port geometry. Consequently, to carry out a flow simulation in both ports in designed chamber side in order to find out its flow character and geometry change reaction.

The Design of a Perimeter Security Solution of an Organization
Dupač, Viktor ; Krejčí, Tomáš (referee) ; Sedlák, Petr (advisor)
This thesis describes the design of a perimeter security solution of an organisation. In the first part of this thesis I am describing some theoretical basics and since chapter six I start describing the main topic of this thesis. In the first logical part of the main topic part I am describing a present situation of an organisation and starting the planning of the solution. In the second logical part of the main topic part I am describing the router Turris Omnia. In that part I am describing this device from different angles. Then next logical part describes the final solution of a perimeter security solution of an organisation. And finally after that there is the part of the evaluation and benefits of this thesis and the conclusion of this thesis.

ICT Selection
Krejčí, Tomáš ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
In my bachelor thesis I deal with the selection and implementation of information systems to the fitness center. Part of the thesis is to assess the current state of the company and make suggestions for improvements. At the end I deal with specific information system, which I chosen, and it´s implementation. Everything is supported by theoretical approaches, which are in the first part of thesis.

Study of connectivity for PV power station
Krejčí, Tomáš ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
Bachelor‘s thesis focused on studying connectivity of PV plant into the distribution system.. The first parts are processed by the conditions of connection of new resources into the distribution system with a focus on photovoltaics. Individual points are taken from the rules of the road grid, which gives the Energy Regulatory Authority. In the second part is given FVS problem. There is a brief history of photovoltaics. More details are described photovoltaic element, its principles, and different types of PV article composition PV panel. There are presented methods of operation FVS. The last section is designed to PVP via PC software.

Up-to-Date Medium Capacity Waste-to-Energy Unit
Krišpín, Jan ; Krejčí, Tomáš (referee) ; Bébar, Ladislav (advisor)
The submitted Master Thesis deals with the technological/mechanical solution of an up-to-date medium capacity waste-to-energy plant. Operational requirements and basic parameters related to a concrete region are specified in the introduction of the Thesis. This is supplemented by a flow-sheet of the plant with the description of main process subsystems. To meet the goals of the Thesis basic balance information is summarized and related schemes included. These data represent principal inputs for the on-site plant as well as basic parameters for the design of key equipment. These pieces of equipment are schematically drawn including their basic parameters and a description of construction. All the available innovative solutions are taken into account. The Thesis provides also a technical-economic analysis for being able to evaluate the overall project.

Incineration plant of middle treatment capacity – flue gas cleaning system
Krejčí, Tomáš ; Kropáč, Jiří (referee) ; Bébar, Ladislav (advisor)
Analysis of the regional energy supply, shows that suitable alternative may be a combination of primary energy sources with the municipal solid waste to energy plant. Starting from the fact that the regional thermal energy needs are characterized by smaller power demand, but relatively significant seasonal fluctuations in heat supply. These factors limit the processing performance of the considered waste to energy plant that could be included in the system of regional energy supply. The aim of the thesis was to propose adequate treatment capacity for regional waste to energy plant and explore alternative solutions in off-gas cleaning for exhaust gases generated during incineration of MSW. The balance sheets of two alternative solutions off gas cleaning are part of the thesis, both in terms of material and energy consumption. Presented evaluation of economic demands alternative arrangement of off gas cleaning includes operating costs and the impact on earnings from energy production.

Systematic approach for medical waste-to-energy processing
Hanus, Jan ; Krejčí, Tomáš (referee) ; Krňávek, Martin (advisor)
This master thesis deals with the current situation of medical waste management in the Czech Republic and available medical waste treatment methods. The first part summarises the legislation of waste treatment and contains an analysis of the current situation of medical waste management in the Czech Republic and comparison to the situation in the European Union. The second part describes medical waste treatment methods and following technologies for energy utilization when thermal treatment method is applied. In the main part of this thesis, a complex medical waste-to-energy system in a model region is designed according to the input data. The design includes description of the collecting and transportation system of the waste, capacity of the unit and suitable thermal treatment and heat utilization technology choice. A calculation model is created for the proposed unit and based on this model, an analysis on energy utilization effectivity is made. As a result of the thesis, environmental, technical and economical assessment is created based on the estimation of the investment and operating costs.

Up-to-date off gas cleaning system for Medical Waste-to-Energy units
Kotas, Dan ; Krňávek, Martin (referee) ; Krejčí, Tomáš (advisor)
This master's thesis deals with current situation of medical waste management in the Czech Republic and it also analyzes the quality of existing units for thermal treatment of the medical waste. In the second part of the thesis, available off-gas cleaning methods were described as well as the emission limits for waste incineration, which correspond to the legislative regulations effective in the Czech Republic. These emission limits are considered as input data for off-gas cleaning system design. In the main part of this thesis, two technological solutions of off-gas cleaning methods for Up-to-Date medical waste incineration unit were designed. The unit is designed for energy utilization of 1400 tons of medical waste accumulated during one year in a regional hospital of model region. From given input parameters, two appropriate apparatus concepts were created. After that, both concepts were evaluated either form energetic point of view as well as from material one. From these evaluations, key apparatuses of both concepts were designed which provided necessary design dimensions for further investment price estimation of each individual key apparatus. In the conclusion of this thesis, the best solution of an off-gas cleaning method was picked according to the comparison of operating and investment costs.
