Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Fireplace for heating
Vítek, Zdeněk ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with combustion of wood in small fireplace, fireplace inlay specifically. This thesis is divided into four main parts. First chapters follow up stoves and their construction. The second parts describes the calculation and design of the stove. The third part focuses on the manufacturing of fireplace. At the end there is a description of experimental measurements produced a prototype, the determination of emmisions and efficiency.

Preparation of materials based on reactive modified polyolefins
Běťák, Lukáš ; Žídek, Jan (referee) ; Kučera, František (advisor)
This thesis deals with a preparation of modified polypropylene. Modified polypropylene was prepared by reaction itaconic anhydride and compounds contain primary and secondary amino group (diaminododecane, aminoethylethanolamine and aminoethylpiperazine). Knowledge of radical and condensation modification of polypropylene were summarized in the theoretical part. New application of modified polypropylene ware summarized at the theoretical part as well. In the experimental part polypropylene was functionalized by grafting with itaconic anhydride during reactive extrusion. Extrusion was carried on the co-rotating twin-screw extruder (Brabender 25 DSE L/D = 34) at 230 °C and 30 RPM. Residence time of reactive blend was 3 minutes. The modified polypropylene PP-g-IAH) contained 0.5 wt% of itaconic anhydride. 2,5 dimethyl 2,5bis(tert buthyl-peroxy)hexane (Luperox 101) was used as a radical initiator. A ratio initiator/monomer was 1:0.6 (mol/mol). PP-g-IAH was used for condensation reaction with amino compounds in molar ratios IAH/amine from 1:0,3 to 1:1. This reaction carried out in single screw extruder (Betol 1825 L/D = 39) at 210 °C and 30 RPM. Residence time of reactive blend was 3 minutes. Fourier transform infrared spectroscopy was used for a calculation of reaction conversion and for description of new functional groups in the materials. This analysis confirmed the presence of amide and imide groups in the samples. Influence of amino compounds to polymer crystallinity was studied by differential scanning calorimetry. Termogravimetric analysis focused on thermal stability of prepared samples and changes of thermal stability was observed in dependence of additives amount. The rheological behaviors of modified PP were analyzed by measuring the complex viscosity.

Solid State Tesla Coil
Pařenica, Jakub ; Mikláš, Ján (referee) ; Martiš, Jan (advisor)
The bachelor's thesis focuses on a theoretical description of the operation of Tesla's transformer, its design, including electronics, and its subsequent construction. The basic theory of the transformer replacement scheme is described. The Tesla transformer is generally described, as well as the methods of excitation of the primary side of the transformer, the generation of the discharge, the skin effect and the meaning of resonance. Furthermore, the work describes the construction of the primary coil holder, secondary coil. The work contains a pattern of the power board from the Eagle program, and everything is accompanied by photos. The work describes the recovery procedure and describes all the waveforms that were measured before and after the connection of the secondary coil.

Secondary and terciary prevention of addictive substance
Kurz, Roman ; Šotolová, Eva (advisor) ; Mlčková, Marie (referee)
My final work is about three basic types of prevention, which are used in the field of narcotic's prevention. It's mostly about secondary and tertiary prevention. Besides the basic terminology you can read about the details of differents preventions, who is responsible for it and also about the treatment of addictive behaviours. In my work you can also find the descriptions of legal and illegal narcotics, which excessive using leads to jones. The questions in the questionaire were created with a respect to the respondents - they are the clients of the mental treatment, who decided to help themselves (sometimes not for the first time).

Krajinářská studie vybraného území
Náhlíková, Barbora
The diploma thesis focuses on a landscape study of specifically chosen area near town of Letohrad. A prerequisite of the thesis was to choose an area, which conceals potential traces of designed landscape. The first part of thesis deals with matters of designed landscapes, landscape evaluation (analysis of primary, secondary and tertiary landscape structure) and identification of designed landscape according to Kulištáková (2014). The result of this survey is finding that the chosen area is indeed a part of designed landscape which is only partially preserved. However, no uniting philosophical idea was found to support the whole composition. That might be revealed with further research. The design part of thesis shows possible solutions for particular problems. For better lucidity is the final design divided into several parts. The first part deals with fundamental matters in the area, for example antierosion system, and reacts to newly proposed road route which is being planned in the actual spatial plan. The second part deals with quality changes.The aim is to produce higher ecological, aesthetic and cultural gains from the area. For example renovation of orchard, new usage of abandoned areas and securing views of Sv. Jan Nepomucký Chapel are elaborated. The third part focuses on renovation of earlier identified designed landscape. Preservation or renewal of particular components or other silvicultural measures are proposed. Furthermore an architecture-artistic study of chosen area is proposed. The centre of the area is Sv. Jan Nepomucký Chapel. The study aims at preserving views on chapel as a dominant of landscape and also preserving chapel as a spiritual space with option for calm walks with beautiful views of region. In the last part of thesis the author proposes declaration of the area as historical landscape reservation Kyšpersko. The aim is to ensure options for renovation and consequential care of designed landscape. For this purpose a standard record for historical landscape reservation is elaborated.

Teachers' Education of Preprimary, Primary and Secondary School - History, Present, Perspectives
Pečinková, Simona ; Váňová, Růžena (advisor) ; Valenta, Josef (referee)
The thesis is a theorethical study with the main theme of teachers' education. It is divided into five chapters. The first chapter describes world trends in the area of teachers' education which are being adopted in the Czech Republic. Next three chapters are focused on the education of each teachers' group - preprimary, primary, secondary school. Each of these chapters includes the historic context of teachers' education and the content of their education. Today's conception of school education is considered as the key faktor which should be reflected in present teachers' education. The fifth chapter contains the perspectives of future development of teachers' education.
