Research and development of progressive protective equipments for horizontal construction using waste materials
Hodná, Jana ; Bydžovský, Jiří (referee) ; Ďurica,, Tibor (referee) ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Large amount of different types of industrial wastes are still not re-use as secondary raw materials in industry. The work deals with finding a new way how to use secondary raw materials, especially the possibilities of using recycled glass from different sources as a fillers in the polymer protective materials development for horizontal structures. The main task of this work is to develop a material with the desired physic - mechanical properties and further verifying the influence of particle shape on their chemical resistance. Result of this work will find advanced protective materials using secondary raw materials as alternatives to be in terms of economic and ecological efficiency replacement for conventional products.

Renovation of sewer network with CIPP methods
Holeš, Petr ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
Diploma thesis makes a summary of today’s state of CIPP methods designed for sewer relining. Thesis presents classification of CIPP methods between other NO-DIG technologies. Then CIPP methods are divided into groups according to the material used for the liner, applied resin, installation method and curing method. Designing of the CIPP liner used for sewer renovation is also part of this diploma thesis. The result of the theoretical part of this work is a table, which states suitability of particular methods for use in a sewer of specific technical properties. Practical part of bachelor’s thesis is dealing with the analysis of defects of an existing sewer in the city Přerov. Analysis was done due to the camera examination provided by the company Wombat s.r.o. Later the table developed in theoretical part was applied, and then the suitability of use of all parameters of CIPP liners was commented. At the end the plan of works is designed, with the plan for pumping of water included.

Conceptual design of a polymeric gear tester in vacuum
Ptáček, Matyáš ; Šperka, Petr (referee) ; Černohlávek, Mikuláš (advisor)
The bachelor thesis deals with the conceptual design of a polymeric gear tester in vacuum. Using a test device, it is possible to test the coefficient of friction in gears. At the beginning of the work is described the issue of operating conditions of satellites in low orbit together with the effects that affect them. Subsequently, suitable polymeric materials are selected, and current publicly available test rigs are described. Based on the research, two conceptual designs are made, one of them is selected and described in detail at the end of the work.
