Manufacture of components "Part of the cover CT"
Dolák, Martin ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
This thesis is about production of part of CT cover. It is part of specific shape which was de-signed to be produced using hydroform technology. The aim of this thesis is to document the steps leading to change the technology into bending and welding. The part has to be split into two different part and new operation list has to be invented. The use of current machine equipment of Exerion company was proved possible by calculations. The final step was de-signing and production of special bending tool. Application of above mentioned was proved by successful production of part.

Desin of new technologies for invert grouting of masonry sewer
Dolák, Martin ; Melichar, Tomáš (referee) ; Drochytka, Rostislav (advisor)
The subject of this work is to find optimal grouting mixture for repairing existing brick sewer with insistence on ecological modesty. Secondary raw and waste materials will be evaluated as a partial replacement of good-quality materials, that are commonly used. Production wastes for which is after necessary adjustment found usage in another sphere of production are named secondary raw materials. In the end will be made a selection of appropriate secondary raw materials for a project of new technology of back grouting identified for repairing currently used brick sewers.

Development of new grouting materials for reverse grouting of sewers
Dolák, Martin ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
ABSTRACT This thesis deals with the development of silicate based reverse grouts for the purpose of rehabilitation of sewers. The work also examines the possibility of substitution of basic input raw materials with secondary raw materials, meaning replacements of both filler components and binder components. As secondary raw materials, we refer to wastes from the production process which, after the necessary treatment, are used in another production. The development and experimental verification of the functionality of the developed grout was focused mainly on the use of secondary raw materials as much as possible, while maintaining or even improving its physical and mechanical properties. Based on the results of the work, it can be stated that with a 100% replacement rate of filler components in combination with 20% replacement rate of binder components, it is possible to largely maintain the properties of the material, or even optimize them. The results of the thesis also point to the possibility of reducing the economic and environmental demands of production of building materials.

Production of a Printing Machine Waste Track
Dolák, Martin ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
Řešenou součástí je část kanálu pro odpadové odstřižky tiskařského stroje. Relativně jednoduchá součást vhodná k výrobě tvářením za studena. Diplomová práce navrhuje zhotovení komponenty lisováním. Po shrnutí základních teorií dále navrhuje varianty výroby. Pro vybranou sestavuje technologický postup a navrhuje kroky tváření. Návazně odvozuje návrh konstrukce postupového nástroje. V neposlední řadě se věnuje ekonomickému vyhodnocení výroby, ročnímu výrobnímu množství a vypočítává bod zvratu pro dané řešení.

Nonlinear regression in R programming langure
Dolák, Martin ; Malá, Ivana (advisor) ; Bašta, Milan (referee)
This thesis deals with solutions of nonlinear regression problems using R programming language. The introductory theoretical part is devoted to familiarization with the principles of solving nonlinear regression models and of their applications in the program R. In both, theoretical and practical part, the most famous and used differentiator algorithms are presented, particularly the Gauss-Newton's and of the steepest descent method, for estimating the parameters of nonlinear regression. Further, in the practical part, there are some demo solutions of particular tasks using nonlinear regression methods. Overall, a large number of graphs processed by the author is used in this thesis for better comprehension.

Marketing Communications and Efficiency of Marketing Communication of the Dance School Hes
Dolák, Martin ; Vávra, Oldřich (advisor) ; Taraba, Jan (referee)
The theoretical part of the thesis is dedicated to a review and an assessment of a communication mix and a marketing communication. There are described the particular components of the marketing mix, the attributes of the services marketing and the tools used for the marketing research. The practical part of the thesis is focused on analysis of a current state of the communication of TŠ Hes and its rival companies. The aim of the work is to reveal the weak spots of the marketing communication and subsequently to provide a solution through a realization of particular marketing actions. The main effort is dedicated to improve the ability to attract new clients. The conclusion provides an evaluation of the marketing interventions and additional suggestions for an improvement of the marketing communication of the TŠ Hes.
