Cascade Sierpinski monopole
Kadlček, Jiří ; Tkadlec, Roman (referee) ; Všetula, Petr (advisor)
This master’s thesis describes the theoretical analysis of the Sierpinski triangle structure. On the basis of this structure, a planar version of the Sierpinski monopole is firstly designed. Then, by using a transfer of the planar motive to the conical surface, conical and cascade Sierpinski monopoles are designed. All simulations are calculated by CST Microwave Studio 2011. In the thesis, four types of cascade Sierpinski monopole are proposed. The investigated parameters are reflection coefficient, input impedance, radiation properties, polarization and bandwidth. The attention is primarily focused on the design and experimental verification of the selected conical shape cascade Sierpinski monopole set on the bands GSM 900, GSM 1800 and Wi-fi 2,4 GHz.

Cascade Boiler Houses of System Regulation
Smola, Vojtěch ; Rubinová, Olga (referee) ; Formánek, Marian (advisor)
This bachelor’s thesis is about designing cascade of condensing boilers and regulation for four storey house with unheated basement. Cascade consists of three condensing boilers that are controlled by the three-zone weather-compensated control. Heating systém is controlled via shung circuit with electronically controlled mixing valves. The heating system is designed to ensure the smooth function of the heating systém and the boiler operates as the largest part in condensing mode. In this thesis were designed mixing control units and control valves to operate across the range. The proposed heating system meets the requirements for housing corresponding to European standards.

Heating and hot water of pension
Beneš, Josef ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
The Bachelor thesis deals with heating system and preparation of hot water for a boarding house building. In the thesis is introduced fundamental systematics of heat line water systems and heating distribution. By the most frequently used materials are identified advantages, disadvantages and possibilities of application. Piping joints are divided according to disassembleability and single options are furthermore described. In the calculating part is analyzed the particular building based on its characteristics. According to this analysis is the building classified from the viewpoint of energetic demands and therefore was determined its “Building envelope energy label”. Based on those and additional data was designed the heating system in correspondence with national regulations. Suggested solution takes in account efficiency, comfort, acquisition and operating costs.
