Short-term and medium-term rehabilitation plan for selected sewer network
Chromík, Radek ; Lžičař, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The author of the thesis deals with the issue of the short-term and medium-term rehabilitation plan for selected sewer netwotk. Resolved area for this work is the town of Břeclav. The Contracting Authority selected the area of interest that falls within the cadastral territory of Břeclav - Poštorná. The aim of the thesis is to elaborate a short-term and medium-term strategy of remediation of a selected part of the sewerage network for the need of a recovery plan.

Simulator of typical rotational machinery components faults
Vaľko, Matej ; Beneš, Petr (referee) ; Čala, Martin (advisor)
The objective of this thesis is to create a library in programming environment LabVIEW by company National Instruments, which objective is to simulate vibrations of different mechanical components, such as shaft, rolling element bearings, plain gearing and planetary gearbox in different circumstances and failures. The theoretical part contains information about typical failures of this mechanical components and their typical failure frequencies obtained from literature. In the description of theoretical part is inscripted simulator with user interface in already mentioned programming environment LabVIEW. Result of this thesis is library, which images time course of vibrations and spectral analysis for diffrent components with their respective failures.

Design of conveyor of couplers
Klár, Pavel ; Ripel, Tomáš (referee) ; Krejsa, Jiří (advisor)
This thesis is focused on the design of conveyor of couplers with regard to the requirements for the resolution, and consisting of several parts. The first part outlines the given issue, short research study and an idea of solution. The next part concentrates on the structural design of the whole conveyor. Then the description of the first part of the conveyor including the structural design and the required calculations follow. Finally, other conveyor parts, the budget and the instruction manual are explained. The thesis includes the related drawings and all necessary calculations for other conveyors parts as well.

Technology solutions with a CNC machine
Baklík, Lukáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with the production of rotary component (master shaft). In the first part is selected suitable semi-product for the specified component, followed by the assignment of production machines and choise of the appropriate tools. Covered is a technological process, capacitive calculation of VBD and energy consumption including respect for the ecology of production. In the next part the NC programs are created in the control systems called Yasnac and Heidenhain iTNC 530. The final part is devoted to the production of the specified component.

Sheeting of Foundation Pit
Vodáček, Ondřej ; Chalmovský, Juraj (referee) ; Glisníková, Věra (advisor)
First part of the thesis talks about pit sheeting in general, including shafts and trenches as well as pits, however pits are the very main topic and therefore described in details. This part also discusses earth pressure and groundwater issues as applied loads, yet only marginally. Second part demonstrates a particular sheeting structure and its calculation. All presumptions are established here, including double-anchored sheet pile wall geometry, spoken earth pressure loads and groundwater loads plus heavy equipment load during a construction. The calculating process is shown using computer softwares (Plaxis 2D, GEO5) and also in a non-software way using just pen and paper. At the very end of thesis an ultimate limit state (ULS) of sheet piles is assessed, software and non-software results are compared to each other and discussed.

Production of rotational parts on a CNC machine
Hort, Zbyněk ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The main theme of this thesis is a design of rotary part (shaft) production. The study contains the choice of semi-finished product, technological procedure, manufacturing instructions, design and description of machines and tools. It also includes a production drawing of a shaft and NC program by which a functional sample was produced. The economic evaluation is at the end of the thesis. The thesis meets all requirements needed for shaft production using CNC machines.
