Svoboda, Lukáš ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
Documentation of project in degree for realization of two floor detached house with fitness centre situated in locality Račice-Pístovice near Vyškov. Building is designed with regular elongated rectangular ground plan of the second floor, in the first floor is larger by fitness centre with the ground floor in the L-shape. Building envelope will be made of exact blocks Ytong with external insulation certified system and with wooden frames of windows with insulating glazing. House is gabled. The idea was to design building envelope energetically efficient with classification class of penetration of heat as B - efficient.

Study of energy consumption reduction of block of flats
Svoboda, Lukáš ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.

Optimization of creation of the price offer
Svoboda, Lukáš ; Samek, David (referee) ; Aigel, Petr (advisor)
The diploma thesis deals with problems of calculation of price offers. The theoretical part provides a breakdown of costs and their determination, explains the division of public contracts by the expected values and the conditions of qualification of candidates. The practical part of this thesis explains the optimized procedures of price offer of the specific building company, in preparing the direct and indirect cost on an example of the public contract. In conclusion the price is compared to the real costs.

Analysis of Travel Agency Customer Satisfaction and Suggestions for its Improvement
Svoboda, Lukáš ; Pšenička, Martin (referee) ; Chlebovský, Vít (advisor)
This thesis focuses on increasing the customer satisfaction of travel agency. Customer satisfaction is a key component for maintaining market position, company reputation and its growth. Client satisfaction is especially important in the area of services, including travel agencies. Based on a questionnaire survey among customers, using the NPS method and the KANO model, measures are designed for increasing it. Also the suggestions are obtained to improve company promotion with the use of customer survey.

Braking marks creation analysis in dependence of vehicle deceleration
Svoboda, Lukáš ; Panáček, Vladimír (referee) ; Vémola, Aleš (advisor)
The work is divided into two parts – theoretical and practical. The first, theoretical part is focused to introduce the problematics to the reader, describing the concept of translation motion and brake physics, defining terms adhesion and friction, skid, calculation formulas etc. After the mechanics chapter follows the chapter about tire and its composition and properties, and a brake system chapter, describing Anti-lock brake system (ABS) and some other important brake-support systems. Second part of this thesis is focused on practical side, which contains acceleration measuring and skid marks creation, followed by evaluation of measured data in form of calculations and graphs.

Monitoring of dynamic systems with piezoelectric sensors
Svoboda, Lukáš ; Hadaš, Zdeněk (referee) ; Kšica, Filip (advisor)
The aim of this diploma thesis is to describe localization and calculation load identification of dynamic systems using piezoelectric sensors. Finding methods, which would allow us to evaluate loads on simple systems is the key to their application in the structural health monitoring of more complex systems. A theory necessary for understanding and application in aerospace, civil engineering, automobile industry, and train traffic of presented methods is given in the first part of the thesis. In these applications, the methods of wave propagation and different types of neural network methods are used to evaluate load identification. It is possible to evaluate loads by using a time reverse method, a method based on signal deconvolution, and a method based on a voltage amplitude ratio of the piezoelectric sensor. In the next part, the methods are described, the suitable place for gluing of a sensor, and the number of sensors for using method is given. These methods were verified and compared to a simple experimental system. In the following part, the model of the piezoelectric sensor is presented. It is possible to use the model for calculating voltage output from the strain. For methods verification, the problem of train passage in a specific place of the railway is chosen. The speed of the train and its load on the railway was calculated by using these methods.

Calandering of li-ion electrodes and its impact on the final capacity of lithium-ion cell
Svoboda, Lukáš ; Kazda, Tomáš (referee) ; Čech, Ondřej (advisor)
There is an effort to produce lithium-ion batteries with maximal density of energy, or higher capacity of cell with the same size. Calendaring of electrodes is important part of manufacturing of batteries. Its parameters, mainly the pressure of calendaring and with it related the final compression ratio of electrode layers, affect parameters of battery significantly. It is the process of pressing electrode material coated on current collector with certain pressure and it reduces its porosity and thickness. The aim of this bachelor thesis is determination of suitable level of calendaring that increases specific capacity, but does not reduce its cyclability.

The Restoration and Novel Utilization of the Zlín Chateau
Svoboda, Lukáš ; Schnapková, Radka (referee) ; Vojtová, Lea (advisor) ; Kalousek, Lubor (advisor)
This thesis deals with restoration of the historic building of the castle. Designed building is located in the city center of Zlin, in a large park. The castle has four floors. It has four wings, which creates a compact unit. Restoration of the building is focused on the design of the new functional use of space and restore the overall appearance. The renovated space will be used for exhibition areas and the hinterland town of Zlin Museum and the Museum of Architecture. In other areas is designed restaurant, cafe, hotel and studios. Part of recovery is design the space in front of the building of the castle.

Technological design of the single-part production of former
Svoboda, Lukáš ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This dissertation in the engineering study of the Engineering technology deals with the proposal of the unit production technology of two pieces of the tool for cold forming of the material X 45 NiCrMo 4, standard W. Nr material number 1. 2767. The production is on the demand and is therefore trial, because the specified tool has not been till now fabricated. The thesis describes an analysis of manufactured components, as well as a description of the material used, a description of the available technologies that were used and a design of production technology. The production will include these methods: turning, grinding, electro erosive deepening and polishing.

Synthesis and characterization of sulfurized polymers for electrochemical power sources
Svoboda, Lukáš ; Kazda, Tomáš (referee) ; Čech, Ondřej (advisor)
Batteries based on lithium-sulfur technology have the potential to increase the amount of stored energy in comparison with current lithium-ion systems while maintaining the same weight. Achieving this goal is possible due to the high theoretical energy density of sulfur, which exceeds the values of other materials used in batteries. However, these batteries suffer from several failing, which still hinder the practical use. The use of amorphous sulfur instead of its crystalline form might lead to increasing of durability and charge efficiency. Inverse vulcanization of sulfur seems to be the perspective method for the preparation of polymer sulfur because it prevents its recrystallization and stabilizes amorphous sulfur. The aim of this thesis is the preparation and study of properties of materials made of inverse vulcanized sulfur.
