Piston Rings of Modern Petrol Engines
Cupák, Václav ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with issues of piston rings used in modern petrol engines. The first part is focused on describing of functions and requirements with which piston rings must deal with. Next part is aimed on shapes of piston rings. Materials from which are piston rings made of are part of third chapter. For proper function, it is important to make some surface treatment. The last chapter contains surface treatment of piston rings.

Usability of stillage from ethanol production
Audy, Dan ; Večeř, Marek (referee) ; Leštinský, Pavel (advisor)
This work solves the use of stillage from ethanol production. Also solves processing into material DDGS and then solves the material and energy balance. This material and energy balance was calculated for 7070 kg of stillage per hour. The final energy requirements of the process were based on the amount of stillage produced to obtain 1 m3 of ethanol. The results of this work offer an insight to the problems of processing stillage. Thanks to conversion for 1 m3 of produced ethanol, results is also offerring the possibility of fast conversion of an approximate energy needed for devices of other capacities.

Piston Rings of Modern Diesel Engines
Homola, Petr ; Knotek, Jiří (referee) ; Raffai, Peter (advisor)
This bachelor thesis concentrates on piston rings and is divided into several points. First point deals with the functions of piston rings and with the demands for them, in the second point there is a division according to the type of the ring and constructing solution. Another chapter deals with materials that are used the most when fabricating piston rings and the last chapter deals with the surfacing that is used the most.

Detached house with two flats in Otradov
Myška, Jan ; Sobotka, Jindřich (referee) ; Kolář, Radim (advisor)
The subject of this bachelor´s thesis is the process of building the technical part of the project documentation for the realization of a detached house with two apartments in the village Otradov. The building is architecturally designed so that projects from the rural architecture. The house has a floor with attic and partial basement. Roofing is using two different height shelves. The building is designed structural system Naturblock. This bachelor´s thesis is on theme layers of roof sloping roofs.

Selected objects in non-euclidian metrics
Bruna, Jiří ; Zhouf, Jaroslav (advisor) ; Dvořák, Petr (referee)
This bachelor thesis studies the shape of a circle, ellipse, hyperbola and parabola in the taxicab metric, using elementary mathematical methods. It thus constitutes a material suitable for the study of this topic without special requirements regarding knowledge in the field of mathematics on the part of the reader. There is a number of illustrations accompanying the text, most of them created using GeoGebra software. Major hypotheses concerning the shape of the above mentioned objects are supplied with a proof. With its scope and margin, the paper represents a unique work in mathematical literature written in the Czech language at the time of its creation. The secondary benefit of the development of an open mind is mentioned as well.
