Changes in the composition of the company's fleet in relation to the EU's "green deal" objectives
Tobiášová, Eliška ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
The purpose of this master thesis is to examine the so-called Green Deal and the related directives and regulations that are intended to help achieve the objectives set out in the Green Deal, as well as to analyse the fleets of the Member States of the European Union and the company with which cooperation has been established as part of this work. The thesis describes the Green Deal and its objectives. The European Union directives and plans with the aim of reducing CO2 that are currently approved or are yet to come into force are also mentioned, while at the same time they are compared with the directives and targets in force in the EU Member States, including the Czech Republic. In the following chapters, a brief description of the cars by type of fuel is given in order to follow a detailed analysis of the fleets of Germany, Sweden, Spain, Slovakia, France, Poland and the Czech Republic. This analysis is carried out using graphs and official statistics available from government institutions. Furthermore, an analysis of the company's fleet is made, summarising in tables the parameters of the vehicles available to the company. The results of the fleet analysis are also summarised in graphs based on the year of vehicle manufacture, emissions, and fuel type. In addition, an analysis of hybrids and electric vehicles currently in the company's fleet is also provided. This analysis works with data provided by the company and examines the cost of driving these vehicles, consumption, and battery usage ratio. Finally, a suggestion is made for the replacement of the current vehicles with the aim of saving emissions.

Design of linear motor with permanent magnets
Čech, Jan ; Bulín, Tomáš (referee) ; Knebl, Ladislav (advisor)
The first part of this thesis deals with the study of linear motors. The introduction of the thesis deals with the brief description of the linear motor, including its accessories. This part explains principle of linear motors, their general advantages and disadvantages. The next section contains an overview and division of the currently used linear motors. Each type of currently used linear motors is briefly introduced and also its principle and characteristics are described, including its specific application. The second part of the thesis deals with the design of an equivalent magnetic circuit model of a linear iron-core linear motor. Hereafter, the proposed design will be used to simulate the distribution of magnetic flux in the linear motor. The evaluated flux-density distribution in the air gap is later compared with the results obtained with finite element method. The thrust is then calculated from the flux-density and the estimated value is compared with the value listed in datasheet.

Microphotovoltaic systems
Nováček, Richard ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with photovoltaic components and their principles. Evaluate the types of photovoltaic systems and their impact on the transmission system. The thesis deals with financial support to small and micro-photovoltaic systems, which can be used in terms of legislation of the Czech Republic. There are also described the changes in the amendment to the energy act and effect on the price of electricity in households. Compared with the domestic photovoltaic rest of the world and the view of the German energy concept. Part of the theoretical design of a hybrid photovoltaic plant, including the use of heat pump. Thesis deals with using hybrid photovoltaic plant and economic viability of the proposed system. The last part deals with the implementation of the proposed system and assesses the true value from those anticipated in the design.

City House – Mixet Use Architecture
Starý, Ondřej ; Urbášková,, Hana (referee) ; Menšíková, Naděžda (advisor)
The main goal of the project is to design a city house near the central part of Brno as an alternative for the existing monofunctional zones and finding out the most suitable functions for the area. The idea is based on a compact city block which communicates with the events on the streets and connects them together to the house via inner atrium. Within the intensive urban structure, housing was chosen for the most important component because nowadays it disappears from the city centres. As the prerequisite for the high-quality living, the residential floors were raised on a three-storey platform which integrates the culture, offices and the commercial use. The roof of the platform is also used as a green roof terrace with a lot of vegetation which protects the living against the polution and noise from the traffic. So it becomes a safe and calm place for the relaxation and children´s games in a busy part of the city. The important point of view where the emphasis was placed was connecting all the functions together not only within the house itself, but also within the range of the whole city. The house functions and the street area are mutually connected via inner public atrium which becomes the important people meeting site. The residential floors are connected to the rest of the house through the large roof skylight which allows the sun rays to reach the lower floors. So the city house doesn´t hide its purpose on its own, but rather "lives together with the city".
