Assessment structures of industrial buildings in terms of ISO 13822
Kirschbaum, Adam ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This diploma thesis deals with the evaluation of the constructions of the industrial buildings according to the ČSN ISO 13822 Standard. In the first, theoretical part, the procedures of research and evaluation of existing reinforced concrete constructions based on the ČSN ISO 13822 and ČSN 73 0038 Standards are described. Further, the theoretical part is focused on the diagnostic methods used during the evaluation of these constructions. The practical part focuses on the evaluation of the three industrial reinforced concrete buildings. It includes information about the building, the description of defects, diagnostics and the appraisal of measuring. The last part deals with a static calculation of selected parts of the supporting construction.

Realization of technological steps gross upper building construction of ski facilities in Kouty nad Desnou
Jandová, Renáta ; Liška, Pavel (referee) ; Kovářová, Barbora (advisor)
The main subject of Bachelor thesis concerns two technological phases of roughly build upper building of ski areal in Kouty nad Desnou. The building serves as a dinning and bowling centre. In particular there are three restaurants. The object is located in the centre of the village, under the ski slope. It will be used all over the year ass entertaining centre. The building has one floor bellow and two above the ground. The construction is made like monolithic core structure with Porotherm brick blocks. The individual technological phases focus on the vertical supporting constructions in second floor and monolithic ferroconcrete roof above second floor. In pursuance of second task, the thesis compares financial and time point of view of two technologies of making vertical supporting walls.

Similarity of bitmap images
Šilhán, Jiří ; Mareš, Martin (advisor) ; Zitová, Barbara (referee)
In the present work we study methods used for content based image retrieval. We analyse features based on color, shape, texture and spatial relations. We review methods for construction signatures based on this features and their comparison. We touch the segmentation techniques and methods for obtaining hidden semantics in image content. At last but not least ve study some of evaluation metrics for content based image retrieval systems.

Manufacturing of mudguard holder using forging technology
Ondráček, Miroslav ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

Construction of hydraulic bending machine of steel sections
Kluka, Ladislav ; Pavlík, Jan (referee) ; Matějka, Petr (advisor)
This master’s thesis deals with design of a hydraulics bending machine. Bending machine will be used primarily for bending reinforcement bars in the shape of stapes. It consists of bending, sliding and chute system, which are located in the machine frame. Drive of each system is provided by a rotary and two linear hydraulic motors. Then there is described a hydraulic system and selection of its most important parts. Work is supplemented by visual documentation in the form of images of individual systems were processed in a CAD system Inventor 2010

Men's antifeminist identity - critical analysis of men's critique of feminist men.
Pavlas, Tomáš ; Havelková, Hana (advisor) ; Matonoha, Jan (referee)
The general question of this diploma thesis is the compatibility of present ideas of masculinity with democracy. The thesis narrows down the field of study onto men's antifeminist identity and maps out the variety within men's antifeminist movement. The methodology of the presented research is based on semantic and discursive analyses. The identity of antifeminist men is not studied independently, but by the means of a critical analysis of the antifeminist men's construction of their relationship to feminist men. The analyzed material consists of texts in which men are critical of feminist men. The thesis shows in what ways antifeminist men use diverse discursive techniques to construct various images of feminist men, images of themselves, and images of their mutual relationships. Great attention is also paid to a critical analysis of such constructions delivered from the perspective of gender studies and men's studies; the position of the author of this thesis is also explicitly acknowledged as a departure point for a critical reflection of the discussed images, their relationships and mechanisms of their construction. Further, a collection of social practices by means of which antifeminist men contribute to the construction of "reality" are introduced. The studied case of antifeminist identity is put...

CFD Simulation of Turbocharger Regulating Mechanism
Drdla, Adam ; Vančura, Jan (referee) ; Svída, David (advisor)
The aim of this thesis is to provide research into turbocharger regulation, and analyze the force load of vanes in the VNT mechanism of Garrett turbocharger by CFD simulation. In the thesis there is one model with two different mesh densities. It describes the relevance of supercharging vehicle engines and the kinds of supercharging aggregates in the introduction. Then, the thesis is divided into two chapters. The first chapter provides research, describing primary principle of supercharging, turbocharger construction and kinds of air regulation. The practical part of the thesis solves the force load of VNT mechanisms. It was necessary to optimalize the 3D Garrett turbocharger model, create two meshes with different element densities, specify boundary conditions and analyse the results of both cases. A general description of solved problems, comparison of results of force load vanes and propose simplifying and verifying the CFD calculation are included in the conclusion.

Manufacturing of separation subrack for rolling stand.
Trčka, Libor ; Štyl, Pavel (referee) ; Daněk, Ladislav (advisor)
The project elaborated in terms of engineering studies concern with project of a manufactural process of separator weldment and of an economical analysis of a production calculated for one item of a weldment and one item of a casting. During elaboration this project there were used all obtainable norms and technical bibliography. In literery studies there are summarized important knowledges related to welding constructions, welding technology, heat treatment and checking fusion splices. There was choosed box construction for this separator weldment. That is designed of two types of material. First of materials S355J2G3, EN 10025 is used for structural parts and the second material S235JR, EN 10025 is used for stiffering pars. The propriety checking of this construction and used materials was performed by Finite Element Method. After calculating costs of production of both variants we can say, that the costs of production of one piece seperator weldment are considerably lower, than costs of production of one piece of casting.

Trailer frame PILLAR for transport concrete pillars
Urban, Jiří ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a trailer used for transporting concrete pillars. The main part of the thesis is focused on frame construction. For the calculation of load states a multi body system was used, whereby a simulation of transport in terrain was performed. The results from these calculations will be used as limiting conditions for strength control. The method of solution is the finite element method. All acquired results will be analysed and according to them changes will be made to the frame construction. In addition to this, the thesis contains drawings documenting the above-mentioned changes.
