Switched power source for electroplating
Janků, Roman ; Minárik, Vladimír (referee) ; Červinka, Dalibor (advisor)
The thesis deals with the switching source for electroplating. The theoretical principles of galvanizing, the optimal technological process and a list of most commonly used metals are described. There is also a list of well-known producers, and a description of their resources for electroplating, which have the same output parameters. In the second part of the work there is an introduction of the already-completed school source 2000A/20V, major technical imperfections is solved there. There is also proposition of technical layout made in 3D AutoCAD. Finally, there is an economic analysis of the production costs of the source and a research in suitable suppliers of components and materials. The thesis contains an estimate of the selling and total price compared with competition.

Electrically conductive surfaces for 3D printed structures
Šomšák, Martin ; Mikulášek, Tomáš (referee) ; Láčík, Jaroslav (advisor)
This thesis describes the technical possibilities of coating various 3D printed structures by different coating methods. Different surface structures have been created on two models for two 3D printing technologies. Antennas on FR4 and PLA substrates were simulated. After adjusting the dimensions of the antennas in the simulations and the results obtained from the simulations, two speckle antennas on PLA substrate were created. To form the antennas, the substrate was coated with copper foil and electrically conductive spray. Subsequently, the antennas were measured, and the results were compared with the simulations.

The Study of Purchasing Company Strategy
Pospíchalová, Eva ; Heřmánek, Martin (referee) ; Jurová, Marie (advisor)
This diploma thesis analyzes the current state of company´s purchasing strategy. In the introduction is described the company and its production program, followed by theoretical part of the thesis. The suggestion part deals with the application of the issue to the practical example as well as the calculation of savings as a result of the purchasing strategy change over.
