Network Infrastructure Design for Family House
Svoboda, Milan ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
This thesis deals with the network infrastructure design for family house. The default aspects for the design of network infrastructure are house plans and requirements of the client. The work presents the theoretical knowledge necessary for further analysis of client requirements and design optimal solution. Part of the work are cabling plans, location of active elements and cost calculations to build the network infrastructure.

Microcosm on the Road
Svoboda, Marek ; Zein, Lynda (referee) ; Kristek, Jan (advisor)
Although there is an international vehicular consensus about signing, the maximum speed allowed or connecting the most significant regions together, their nature is different all based on geographical, cultural or social conditions. Rest stops along the roads reflect each country dispositions. Rest stops are the place where different social and national clusters meet. At this moment building up the rest stops is on behalf of the Czech republic which is not that much interested in it. Instead of taking care and maintain them, because the current state of the reststops is not satisfactory, the Czech republic is letting them to the third parties - supranational corporations. This leads to unpleasant lines along the highways accompanying by petrol stations and cheesy fastfoods. There is no place for rest stops without the need of consummation. The Czech republic has currently begun planning and building up new kilometers of highways and the new opportunities of rest stops arise. Because the existing site is overloaded with petrol stations, supranational corporations are no longer interested in these plots. State has an opportunity to take over and redesign these neglected plots on his own.

High speed steel milling cutters made by powder matallurgy
Svoboda, Martin ; Sámelová, Vendula (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis is a research work describing milling cutters made of high speed steel by powder metallurgy (HSS PM milling cutters). In chapters one, two and three are generally described milling, high speed steels and powder metallurgy. In chapter four are introduced particular HSS PM milling cutters of a few producers. The summary contains mechanical properties of cutters and suitability for machining. It is focused on main type of HSS PM cutters, which are the end mills.

Pozitive and negative selection of mitochondrial genome
Svoboda, Matěj ; Škutková, Helena (referee) ; Maděránková, Denisa (advisor)
This bachelor thesis deals with positive and negative selection detection in mitochondrial genome of invertebrates and vertebrates. The component of this paper is to interpret the theory of evolution and evolution models. The main objective of this bachelor thesis is to formulate the algorithm package for a positive and negative selection detection in a program environment, RStudio. Consequently, outcomes of algorithm are compared to values acquired by tool PAML.

Differential protection of transformer.
Svoboda, Miloslav ; Paar, Martin (referee) ; Toman, Petr (advisor)
This bachelor thesis is divided into several chapters, which consist of two main parts of the work, theoretical and practical. In the theoretical part the work deals with disorders of electric network, causes and limit of their adverse effects. Further it theoretically analyses the function of electrical protection, requirements for the protection , their basic elements. Then there is described the principle and function of instrument transformers and the differential protection of transformers. The practical part of the work deals with protection for a specific transformer. The proposal involves the calculation of three-phase short-circuit, the selection of differential protection, the proposal of instrument transformers and settings of the protection function.

Hot Water Grate Boiler
Svoboda, Marek ; Šilhavý, Karel (referee) ; Lisý, Martin (advisor)
This thesis deals with design of hot water grate boiler, where the output is water with parameters 130 °C and pressure 16 bar. In the content of the whole thesis is gradually introduced a stoichiometric calculations, which is based on the specified fuel – wood chips. This is followed by the design of the individual heating surfaces according to the thermal calculations given in the thesis. Finally, the calculation is extended by hydraulic and aerodynamic losses. Dimensional design, as a basic scheme, is shown at thesis. More detailed drawing documentation is attached to this thesis.

Dictation System - User Interface
Svoboda, Martin ; Fapšo, Michal (referee) ; Schwarz, Petr (advisor)
The term dictation system we understand the software system, which consists of two main parts. The first part is recognizer spoken word, the second is the user interface for user interaction and processing output recognizer. This work focuses on the user interface dictation system, a description of comunication between the recognizer and the user interface, the correction of words coming from the recognizer and transfer numbers from verbal to numerical form.

Research on the textured journal bearings for engines in automotive
Svoboda, Martin ; Hartl, Martin (referee) ; Omasta, Milan (advisor)
The aim of this thesis is to describe the effect of surface textures of radial journal bearings with polymer coating on friction and damage development using experimental tests. Wear and friction tests of real bearings with different texture geometries and surface materials were performed. It was found that the wear deterioration of the textured aluminum sliding bearing surface and neutral or positive effects on the wear of the textured bearing with polymer coating. The reason for the improvement is the good resistance to high pressures of the polymer coating and the preservation of the texture dimensions throughout the bearing run. The friction test showed an improvement in the frictional properties of the textured surfaces when the amount of lubricant in contact was insufficient. At the same time, a positive effect on tribological properties was demonstrated by reducing the lateral lubricant discharge.

Design of LED lighting for industrial camera systems
Svoboda, Martin ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
The bachelor thesis deals with the development, design and construction of multispectral lighting for industrial camera systems. The lighting is conceived as a modular device consisting of two parts - a control unit, which can be communicated primarily through the Modbus TCP / IP protocol, which powers, controls and collects information about the connected lighting unit. The illumination unit is equipped with 64 intelligent RGBW light emitting diodes located in an 8x8 matrix and one control diode opposite to which light intensity sensors are placed to give feedback on the color and intensity of the light. There are two temperature sensors located between the LEDs to check the temperature of the lighting unit. Both units are housed in a robust aluminum chassis. The control unit contains a microcomputer programmed in C language
