The printing of the complex shapes by DLP technology from the ceramic materials
Popek, Tomáš ; Roleček, Jakub (referee) ; Spusta, Tomáš (advisor)
This work is focused on the characteristics of advanced ceramics, the basic principles of the 3D printing, and the division of methods for the 3D printing of ceramic materials. It also discusses the removal of the binder from the printed samples, subsequent sintering, and associated TGA analysis and high-temperature dilatometry. Al2O3 ceramic powder was used to print ceramic components, from which two suspensions with a weight fill of 60 and 65 % were prepared. These components have been progressively subjected to TGA analysis and high-temperature dilatometry. The results of the two measurements were used to determine the debinding and sintering cycle. Debinding took place in a vacuum at 410 . As a result, the weights decreased to 63.91 ± 0.45% and 68.62 ± 1.08% of the original weights. The parts were sintered for 120 minutes at 1550 and then the relative densities were measured, which were 87.89 ± 1.05 % and 88.36 ± 0.81 %. The complex components were a turbine with a height of h = 4.4 mm and a diameter of d = 27 mm, a hexagon head screw with a length of 20 mm and an M8 thread, and a nut with a height of 6.5 mm and a width of 13 mm with an M8 thread.

Experimental sets for teaching physics of microworld on secondary school level
Popek, Tomáš ; Koupilová, Zdeňka (advisor) ; Kácovský, Petr (referee)
The focus of this thesis was to find and evaluate the information resources available to teachers, in the context of creating or conducting demonstrational and student experiments in the Physics of the Microworld at high school. Another goal of the thesis was the creation of four sets of aids for experiments from various areas of microworld physics taught at the high school level. These sets contain instructions for teachers and worksheets for pupils. Another goal was to make the sets portable, which all four met. Part of this work is a description of the created experimental sets, worksheets for pupils and texts for teachers. The experimental sets will be stored on the premises of the Department of Physics Education and will be available for loan to teachers for teaching purposes.

Inbound marketing
Popek, Tomáš ; Jon, Jakub (advisor) ; Trnka, Lukáš (referee)
In my work I focus on Inbound Marketing, which represents a new perspective on marketing, that has not been given the attention it deserves. It is a combination of existing and proven marketing methods that are used to obtain new customers with minimal marketing costs to the organization. The first section of my work is devoted to defining the concept of Inbound Marketing definitions and explanations. Furthermore, I present a list of instruments used in Inbound Marketing, and showcase the definition and differences compared to the use of these tools in other types of marketing. In the second part of the thesis, I focus on the introduction of software for the management of Inbound marketing campaigns, their description and evaluation of the end-user perspective. Furthermore, I present a practical demonstration of work in one of these software's based on real client requirements and at the end of my thesis meet the objectives and my opinion on the development of marketing.
