Possibilities of using Crystallization and sealing Admixtures for Concrete in a highly chemically aggressive Environment
Fittl, David ; Slezák, Viktor (referee) ; Hubáček, Adam (advisor)
Previously neglected and today largely run-down agricultural and farm buildings, which have not been properly maintained, are in a dilapidated state. In recent years, however, farmers and husbandmen have been trying to create a greener and more sustainable environment. Therefore, construction companies and concrete manufacturers are under pressure to produce more resistant concrete structures with enhanced durability for buildings that must withstand aggressive environments. This thesis summarizes the current knowledge of the durability of concrete exposed to highly chemically aggressive environments; it provides a summary of the knowledge of individual types of crystallization additives in concrete; and it includes descriptions of the various types of environment affecting concrete and descriptions of agricultural and farm buildings.

Possibilities of increasing durability of concrete in highly chemical aggressive environment in agriculture
Sláma, Radek ; Slezák, Viktor (referee) ; Hubáček, Adam (advisor)
In recent years there has been a significant increase in the production of concretes for agricultural buildings, especially in the area of exposure to higly chemically aggressive environments. The aim of the thesis is to describe and summarize the existing knowledge about the durability of concrete exposed to the effects of highly chemically agressive environment. Furthermore, emphasis is placed on the description of individual additives and admixtures increasing the resistance of concrete to the effect of harmful substances. In the experimental part, the effects of individual types of additives, admixtures and sealing coatings on increasing the resistance of concrete against the effect of highly chemically aggresive environment are investigated in the laboratory.

Prototype system for centralized control of music effects using Android OS
Slezák, Viktor ; Ilgner, Petr (referee) ; Zvončák, Vojtěch (advisor)
This bachelor thesis had been encouraged by the thought of easily operable sound effects from only one place. Guitar pedalboard can be taken in a consideration as an example, where multiple sound effects are operated by the means of small boxes with several turning potentiometers. When a guitarist wants to change the set up of those sound effects, they must manually reconfigure them separately. The aim of this thesis is therefore development of an application and actuator which enable to operate sound effects from one place by a one-click. The goal is to simplify and centralize the control of sound effects, such are guitar effects in pedalboard, into one application. A single-board computer Arduino and additional Bluetooth module HC-05 are being used for the development. Control systems are run on the Android platform. The text itself deals with the realization of the application, which can remotely control actuator for the sound effects regulation, with the programming problematics, communication via Bluetooth platform and the construction of the solution of actuator with regards to printable method FDM.
