The thesis compiles my contributions to the tilting theory, mainly in the set- ting of a module category over a commutative ring. We give a classification of tilting classes over an arbitrary commutative ring in terms of data of geometrical flavor - certain filtrations of the Zariski spectrum. This extends and connects the results known previously for the noetherian case, and for Prüfer domains. Also, we show how the classes can be expressed using the local and Čech homology the- ory. For 1-tilting classes, we explicitly construct the associated tilting modules, generalizing constructions of Fuchs and Salce. Furthermore, over any commuta- tive ring we classify the silting classes and modules. Amongst other results, we exhibit new examples of cotilting classes, which are not dual to any tilting classes - a phenomenon specific to non-noetherian rings. 1

This thesis is focused on the construction of traffic communications and their influence over the surroundings. The introduction of the work shows reasons leading to the increase of an importance of the road transportation and it appreciates a transport policy and an urban planning. Further work describes transport from the view of public finance and there are mentioned specialities of appraisals of transport projects. Main theme of this thesis deals with construction of peripheral by-pass road around Prague. It concerns on the north-west part of the by-pass road because there are two possibilities of the route location, the south version is supported for a long time, the north version was suggested as an alternative route few years ago because of its better impacts to surrounding environment.

The topic of this work is the renewal of hermetic pipe penetrations within the primary loop of a nuclear power station. A description of the Dukovany nuclear power plant is included at the beginning, ranging from basic description to details of the renewed component and the reasoning for its replacement. Following is a description of the technologies, which are applied in order to restore the hermetic pipes, the choice of the placement of the heterogeneous weld and the compilation of a workflow for the renewal in the environment of the primary loop while maintaining the quality standards and the strict safety conditions. The conclusion includes a calculation of the expenses tied with the chosen variant the reasoning behind the renewal regarding the length of the outage.

The topic of this master thesis is the solution of Brno expressway in section between interchanges Hlinky and Velodrom. The thesis introduces two alternatives of height trajectory of Brno expressway. In first alternative the expressway is above current terrain on the estacade. The local roads are situated under the estacade on the terrain level. The neighboring areas stay intouched. In the second alternative the author presumes the reconstruction of part of the exhibition centre. In this case the expressway is situated on the terrain level and rises up just before interchange Velodrom. The local area is serviced by the new road situated in reconstructed area and by two bridges over the expressway. The next topic of the thesis is the solution of interchange Velodrom. Both alternatives are compared in the end.

The aim of this diploma thesis is a concept of hydraulic (hydrostatic) circuit of rail – road vehicle drive for the drive on communication and railway. As my work is not related to a specific type of road vehicle dedicated to a drive on railway, my work is of strictly reference nature. On request I was provided by Bosh Rexroth s.r.o. with a hydraulic scheme of two-way undercarriage (see appendix), which is also a source material for the new concept. My work is focused on interests of SaZ s.r.o., which deals with the development and rebuilding of road vehicles into rail – road vehicles. The first phase is focused on the choice of the most convenient component of railway undercarriage in accord with the assignment. The second phase is oriented on the calculation of travel parameters, dimensioning of systems with concretization of typal mark of components. A part of the second phase is also a concept of hydraulic braking system of rail undercarriage. After that follows a complete evaluation, eventually an alternative solution of given problem.

This thesis discusses and proposes the route of south-east Big City Ring in Brno. The main objective is to find an efficient connection of roads in Faměr´s square district and a solution for a multilevel junction in Ráječek district. Additionally, the designed concept provides a solution for the connection of the new train station (i.e. new street Zanádražní) to the Big City Ring, crossing with Hněvkovského street and connection to highway D2. This thesis also discusses an axis and profile grade of possible layout of the route.

The main aim of this diploma thesis is to acquaint the reader by the means of research with heat diagrams of nuclear power plants, and subsequently, submit a scheme design of partial components and their involvement to heat diagram. The work also reflects different drive variations of circulation pumps and cooling circuits.

Theme of this diploma thesis is a design of a hydrostatic steering circuit of the Maxterra tractor, where the working medium is oil from the gearbox. Part of the design is also check calculation of the hydrostatic circuit of the steering. Next part is also the design of the steering column. The circuit of the hydrostatic steering and the steering column will be used on the new Zetor Maxterra tractor.

Main target of this master´s thesis is a projection of a thermal circuit of a heating plant, which uses waste heat of a cogeneration unit with power of 1600 kWe. Electric power of a cogeneration unit is supplemented with an electric power produced from a waste heat. All heat is further used for heating in a warm water heating system. Within this thesis are executed projections of a thermal circuit of a heating plant, choice of particular devices, determination of a thermal power of devices and also determination of conditions of particular heat – transferring substances. Furthermore, design of particular devices is made, mainly for basic dimensions and heat transfer.

The topic of this thesis is strength check of hydrostatic steering circuit for Zetor Forterra HSX tractor. Next part of the thesis deals with steering column support structure and pedal group console design including FEM analysis, allowing installation of steering columns of different types.
