Study of rehabilitation alternatives of the selected part of the sewerage network
Dvořák, Pavel ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The theme of this bachelor thesis is elaboration, evaluation and comparison of alternative ways of solving the reconstruction of a part of a sewer network. For this purpose, this bachelor thesis is divided to two parts. In the first part, there is a researchof the metods used for repair and reconstruction of a sewer network, with the greatest emphasis being placed on methods of renovation, whose goal is to improve the functional and operational properties of the sewer. There are also descriptions of technological procedures, usability area and the basic technical parameters from manufacturers. In the second part, the acquired knowledge is applied in the solution of the reconstruction of the real sewer network, namely in the urban part of Znojmo, Znojmo - město, the residential area of Pražská street. Two solutions have been developed. At first variant only trenchless technologies were considered, in the second variant a recovery of the pipeline by open trench.

Cost Analysis of Repairs and Maintenance of an Apartment Building in Brno
Staňková, Pavla ; Hobst, Leonard (referee) ; Klika, Pavel (advisor)
The aim of this diploma thesis will be to create a plan for maintenance and repairs of the building on the street of the brothers Čapků in Brno. The first part will describe the individual concepts dealing with the life of individual structural elements, maintenance and repair and revisions of dedicated technical equipment. The second part will be focused on practice. A plan for maintenance and repairs of the building structures and a plan for revisions and inspections on the dedicated technical equipment will be prepared for the given building. The proposed plan will be designed to spread the funds over the whole period considered.

Passportisation of the Structural and Technical Condition of a House in Vyskov
Karásek, Jakub ; Doležalová, Monika (referee) ; Kosová, Jaroslava (advisor)
In this thesis I deal with the passportization of the building-technical condition of the family house in Vyškov, the creation of its new project documentation and the proposal of repairs including appraisal cost. In the theoretical part I describe possible faults and defects of buildings, also their lifetime and the possibilities of finding their construction-technical condition. I also discuss the theory and usefulness of pasportizations. In the practical part, I evaluate the construction and technical condition of the selected house and make a finding of faults and defects of the structures, including the proposal for their repair and the appraisal cost with the item budget.

Mechanical maintenance of rotating electrical machines
Smejkal, Pavel ; Synek, Miloš (referee) ; Pavlík, Josef (advisor)
This thesis deals with the mechanical maintenance of rotating electrical machines. It outlines the basic division of maintenance and its effects on the function and cost efficiency due to the type of maintenance. Main emphasis is placed on individual maintenance steps, which is done on the rotating electrical machines and then to determine their importance in relation to the causes of failures.

Influence of Bottom Preheating in Rework of Assembled PCB
Čechák, Ondřej ; Bžoněk, Tomáš (referee) ; Starý, Jiří (advisor)
This bachelor's thesis introduces the problematics of physical mechanisms of heat transfer and the correlative mathematical formulas and the use of mentioned problematics in the technology of bottom preheating in the rework of assembled printed circuit boards. It explains the importance and reasons of use of this technology, not merely in the professional production. It focuses on expert analysis of the appliances based on their properties and clarifies the differences in basic types of the devices. The emphasis is then laid on a practical testing of the technical parameters of the preheating devices as well as on an experimental design and a practical testing of a local bottom printed circuit board preheater.

Proposal of rehabilitation of hot water network
Lžičař, Jakub ; Voltr, Aleš (referee) ; Raclavský, Jaroslav (advisor)
The bachelor thesis deals with hot water recirculation systems. It is mainly focused on the malfunctions that appear in the system. Firstly, the text elaborates general information about hot water recirculation systems, hot water distribution and its parts. The next part of the thesis describes materials used in hot water recirculation systems. Then the text deals with the malfunctions of hot water recirculation systems, design and assembly of the pipes. These chapters are followed by the case study. The case study helps to imagine the way of possible future reconstruction. The time schedule of the realization was attached to the bachelor thesis.

Suggestion of the manufacturing technology of a fastener for plastic molding
Duda, Tomáš ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
The diploma thesis convey the information about the creation of technological procedures leading to the optimal way of repairing damaged parts of the fixture and creating production procedures for the production of new parts of the assembly. The theoretical part is focused on the analysis of the issue, determination of material of damaged parts for future production and designed semi-finished product. Furthermore, the technology of production from the point of view of used technologies is discussed. This includes a description of the tool materials. The practical part of the thesis is focused on the design of technological procedures for repairing damaged parts, which must be repaired as soon as possible. For the future production of new parts, the second half of the practical part includes the manufacturing processes including their description. There are evaluated variants of repair and production of new parts at the end of the thesis.

Providing measured documentation of existing structural and technical conditions of a single-family house in Brno
Zahradníková, Lenka ; Najt, Eduard (referee) ; Šmahel, Milan (advisor)
The diploma thesis deals with the passport of family houses and its creation. The first part describes the building condition survey from a theoretical point of view, its advantages, purposes and sorting, possible owners and so its legislative background. Thereafter it describes in detail the procedure of making the passport and applies the procedure on a particular family house in Brno. Medium passport of the family house focuses on describing the structural and technical condition. It also describes the current faults, errors and methods whose reveals them. Subsequently, the proposals for solution of these adjustments follows together with the resolution of emergency in specific cases.

Revision of steam turbines and repair design
Grepl, Martin ; Trněný, Bohumil (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is the revision and repair design of the condensing steam turbine SST 600 in Bielsko-Biala. The thesis deals with the revision of the steam turbine and the repair design of the damaged parts, the overall analysis of the separation of the steam of the split plane and the calculation of the parameters for tightening the new screws. The master thesis is given for a specific case. The introductory part of the master thesis deals with a basic description of the repaired steam turbine. Subsequently, a review of individual disassembled parts is given and the scope of the repairs is stated. In the next part of this thesis are summarized the causes of the steam leakage of the dividing plane at the points of the cross section and in the area of the control stage. The last part deals with the sealing problem of the split plane and the related main part of the master thesis is the calculation of the tightening parameters of bolts in the turbine housing. Another aim of the master thesis is to create drawings of the lightening of the split plane on turbine house.
