An image of the 1949 hockey world champions in contemporary newspapers and its use in propaganda
Svoboda, Lukáš ; Groman, Martin (advisor) ; Suk, Pavel (referee)
This thesis deals with the fate of the 1949 ice hockey world champions, the course of the trial with the group of Bohumil Modrý and pursues the image of the ice hockey generation at the turn of the 1950's in the contemporary press. In detail it analyses mainly the arrest of the national team members, preparation of the trial and the trial itself. The last part of this work focuses on the year 1968 when the convicted ice hockey players were vindicated. The whole thesis is interweaved with excerpts from the period press that illustrate the evolution of the image of the national ice hockey team.

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.

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.

Alandering Of Li-Ion Electrodes And Its Im-Pact On The Final Capacity Of Lithium-Ion Cell
Svoboda, Lukáš
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 article is determination of suitable level of calendaring that increases specific capacity, but does not reduce its cyclability.

Synthesis, Characterization And Centrifugal Force Spinning Of Sulfurized Polymers For Electrochemical Power Sources
Svoboda, Lukáš
Lithium-sulphur batteries have the potential to increase battery capacity while maintaining their weight and volume. This is possible due to the high theoretical energy density of sulphur. However these batteries suffer from several failing, which still hinder practical use. The use of amorphous sulphur instead of its crystalline form leads to increasing of cyclic stability and charge efficiency. Inverse vulcanization of sulphur seems to be perspective method for the preparation of polymer sulphur, because it prevents its recrystallization and stabilizes amorphous sulphur.

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.

Brownfields in the Czech Republic in connection with historical centers
Severová, Anna ; Svoboda, Lukáš (referee) ; Májek, Jan (advisor)
The topic of this Diploma Thesis is the urban design of the structure in the town Náchod in the area of the former textile factory. Several years ago the industrial area of the textile factory in Náchod was sold out. A part of this factory has been reconstructed but bigger part has been demolished. This part is currently the center of interest. The city is trying to get it completely into its property and appropriately build up the area again. The area is located north-east from the center, near the railway station. The aim of the thesis is to design a suitable urban structure. Usefully complement existing houses with new ones. Part of the design of new buildings is a solution to the traffic service, design of functional use and public space proposal. The proposal emphasizes the appropriate connection of the current city to new streets and houses. To make this new city part an integral part of the city.

Brownfields in the Czech Republic in connection with historical centers
Murárová, Lucia ; Svoboda, Lukáš (referee) ; Májek, Jan (advisor)
The subject of the Diploma thesis is an urban study in the area of the former part of Tepna in Náchod. The Tepna area is largely after demolition and is currently dilapidating. This area has the potential for development and use, located within a short walking distance from the historic city center and at the same time from the residential area in the northern part of Náchod. Above the solved area is the castle, which is a dominant and a city landmark. The aim of the proposal was to use the potential of the territory at most, but at the same time to approach the surrounding landscape sensitively and to connect the urban character of the surrounding urban structure of the city and, conversely, the existing buildings of unclosed blocks are supplemented by new development.
