Design and implementation of the software for controlling Agilent leakage mass detectors
Maixner, Jiří ; Arm, Jakub (referee) ; Kaczmarczyk, Václav (advisor)
This diploma thesis deals with the study of leakage problems in industry and the use of Agilent weight detectors for its detection. Based on the studies conducted, a hardware and software solution has been proposed for connecting the measuring elements to a helium detector at a simple configurable station. Additionally, a C# application was created. This application allows the leak detector to be controlled and data collected from the detector and its surroundings. The created application was tested in a real environment. The conclusion of this work is devoted to the possibilities of using the created application.

Effect of heat treatment on the properties of sol-gel deposited ZnO seed layers
Bašinová, Nikola ; Černohorský, Ondřej ; Grym, Jan ; Maixner, J.
Zinc oxide nanorods as a potential material for nanoscale devices are prepared by chemical bath deposition (CBD). The effect of the quality of the sol-gel deposited seed layer on the vertical alignment of the nanorods to a silicon substrate is discussed. Emphasis is put on the investigation of the impact of the heat treatment on the properties of the seed layer deposited by dip-coating. The sol-gel method is a multi-stage process consisting of three principal steps: (i) preparation of a solution with suitable precursors, (ii) deposition of the precursor solution, and (iii) the heat treatment. The preheating needs to be performed to thermally decompose the zinc acetate precursor into zinc oxide seeds. Three different temperatures of preheating are compared (300 degrees C, 350 degrees C, 400 degrees C) followed by annealing in argon at 800 degrees C and the influence on the quality of the seed layers and vertical alignment of nanorods are discussed. When the preheating temperature is higher than 350 degrees C, the seed layer comprises smaller and denser crystallites with a preferential orientation along the c-axis. CBD growth of ZnO nanorods on these seed layers results in their good vertical alignment

Cement industry in selected countries of Central Europe in relation to infrastructure development
Maixner, Jakub ; Vošta, Milan (advisor) ; Bič, Josef (referee)
This master thesis is devoted to the cement industry and its relation to the infrastructure development in selected countries of Central Europe. The aim is to analyse cement industries and markets in the Czech Republic, Slovak Republic and Austria and compare these markets with the infrastructure development in aforemetioned countries. The first chapter defines cement industry and infrastructure. The second chapter focuses on the evolution and contemporary state of cement industries in the Czech Republic, Slovak Republic and Austria. The third chapter devotes itself to infrastructure and its development in Europe and Central European states. The last chapter combines data from second and third chapter and answers the main research question.
