Lubricants in Up-to-date Combustion Engines
Čech, Martin ; Svída, David (referee) ; Dundálek, Radim (advisor)
In my bachelor work I have tried to analyze informations about lubricants in up to date combustion engines. This work deals with motor oils and their viscosity and performance classification The special motor oils for motorcycles are part of this bachelor work too. One of the aims of bachelor work provide informations about gear oils for automatic as well as manual transmissions and their classification. This work describes also questions about additives.

Single-cylinder Engine of a Road Motorcycle
Čech, Martin ; Molcar, Martin (referee) ; Drápal, Lubomír (advisor)
This thesis is focusing on the construction of a four-stroke internal combustion engine for a 250 ccm road bike. Since it is a road bike, the introduction of legislation of the Czech Republic for this category is outlined in the introduction of the thesis. Furthermore, disassembling of similar and competitive engine was conducted. The thesis also describes the process of construction of this four-stroke internal combustion engine. In addition, the thesis compares friction loss on the main bearing crankshaft. In the latter part there is summarization of all findings.

Measurements results assessment and emission limits
Čech, Martin ; Jedlička, Filip (referee) ; Dvořák, Radek (advisor)
Main content of this task is summary and explanation of main methods,which can be used to evaluation the results from measuring of pollutants in combustion gases. The way which should be most acceptable for our datas will be consequently used in a simply example. There will be mentioned the importace of chosing the entering datas and their dependence on outer conditions. Another chapter will be devoted to emission standarts of main pollutants in Czech republic and in chosen world countries too. There will be mentioned the historical developement of these standarts and hypothesis to the future about this question too.

Optical amplifiers for metropolitan and access networks
Čech, Martin ; Šporik, Jan (referee) ; Tejkal, Vladimír (advisor)
Aim of this Master´s thesis is to describe and compare most common types of optical amplifiers used in today’s networks. The first section focuses on problematic of optical transmissions and phenomenon which cause degradation of transmitted signal. It is also explained in this section why there is a need to deploy optical amplifiers. Next section describes basic principles, structure and properties of individual types of optical amplifiers. Following section describes simulations which were made to compare the performance of transmission systems with each individual type of optical amplifier. The last section contains a design of optical metropolitan network with wavelength multiplex. Based on simulations from preceding part best amplifier type and optimal amplifier placement was selected. Functionality of the design was tested and simulations described in final section.

Shopping Center in Ivanovice na Hané
Čech, Martin ; Šmak, Milan (referee) ; Pilgr, Milan (advisor)
Work deals with design of steel structure of shopping center. It is a building with rectangular shape with dimensions 28 x 55 m and a height 11 m and with cylindrical roof with 50 m radius. Main frames are designed with 5,5 m distance and they are made of arc roof truss connected to steel plate columns. Exterior building envelope is made of Kingspan sandwich panels. Roof cladding is designed without purlins and curtain wall is fastened into side rails. Macalloy tension members are used to obtain spatial rigidity of the structure.

Evolution of the Lancia Sport Cars
Čech, Martin ; Beran, Martin (referee) ; Svída, David (advisor)
This thesis deals with the development of Lancia sports and racing cars. The main goal is to clarify design solutins, described them and do an analysis. Alternatively to compare how the competition dealt with the problem. The first part outlines the emergence of car factory and briefly describes the first cars, their design and especially the innovative features. In the second part two successful racing cars from the racing field are decribed and analyzed in detail.
