Realisation of microclimate control system for plants
Fikar, Jan ; Šebesta, Jiří (referee) ; Urbanec, Tomáš (advisor)
The aim of my Bachelor thesis was to design an automatic system that would maintain the perfect conditions for growth and development of indoor plants. Plants kept in human households have specific requirements that are often not met. I measured, altered and evaluated several quantities (humidity, temperature, lighting). The whole system is controlled by microcontroller ATmega32.

Woven antennas
Fikar, Jan ; Pítra, Kamil (referee) ; Raida, Zbyněk (advisor)
The thesis is aimed to design textile antennas that can operate in the ISM band 5.8 GHz. Attention is turned to practical exploitation of these antennas under regular conditions. Variations of the bandwidth of the antenna due to washing and waterproofing will be observed. Finally, the impact of the proximity of living tissue on the parameters of antennas will be studied.

Alternatives to the regime of permission for construction work
Fikar, Jan ; Staša, Josef (advisor) ; Svoboda, Petr (referee)
The purpose of my thesis is to analyze the legal regulation of the public law contract on realization of the structure, which can be concluded under the Section 116 of the Building Act with the approval of the respective authorities between the building office and the developer and the summary building permit proceedings under the Section 117 of the Building Act, which consists in a concluded contract on making a check of the design documentation for the structure between the developer and an authorized inspector. The main aim of the reform of public administration is among others to democratize and more privatize the building permit proceeding and create the alternatives to the classical building permit proceeding. These alternatives are above mentioned the public law contract on realization of the structure and the summary building permit proceedings. The both institutes are capable to replace the building permit. The other purpose of my thesis is to point out shortcomings in the current legislation in connection with the proposed amendment to the Building Act. The thesis is composed of two extensive chapters, each of them dealing with different alternatives to the classical building proceeding. Chapter One deals with the public law contract on realization of the structure and with the connected...

Our modern industrialized society increasingly requires new structural materials\nfor high-temperature applications in automotive and energy-producing industrial\nsectors. Iron-aluminides are known to possess excellent oxidation and sulfidation\nresistance as well as sufficient strength at elevated temperatures. New Fe-Al-based\nmaterials will have to meet multiple casting, processing and operational criteria\nincluding high-temperature creep strength, oxidation resistance and room-temperature\nductility. Such desirable combination of materials properties can be achieved in multi-phase\nmulti-component superalloys with a specific type of microstructure (the matrix contains\ncoherent particles of a secondary phase - a superalloy microstructure). In order to design\nnew Fe-Al-based superalloys, we employ a state-ofthe-art theory-guided materials design\nconcept to identify suitable combinations of solutes.
