The multipurpose hall in Tábor
Tomeš, Martin ; Sýkora, Karel (referee) ; Šmak, Milan (advisor)
In my project I focused on the design of the sports hall in Tabor. As the main construction material was used glued laminated timber. the associated structure was used steel. the structure has a span of 45 meters and a length of 60 m, height of 15.5 meters. For a given type konstruckce I decided for economic reasons to curved beams of glulam supported at the ends.

Simulation of LED retrofits under operational conditions
Tomeš, Martin ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This Master’s Thesis on Simulation of LED retrofits under operational conditions is divided into theoretical and practical part. Theoretical part in the introductory section deals with the concepts of lighting technology and presents some electric light sources, such as classic bulbs, halogen bulbs, linear and compact fluorescent lamps. It also describes the principle of electroluminescent light sources (LED), which discusses principles of yielding a white light, the main advantages of LED etc. The reader is familiar with the issue of compensation the linear fluorescent lamps tubular LED source and with the work environment programme ReluxPro that is used for design of the lighting system. Practical part of the thesis is divided into two chapters. In the first chapter, measured linear fluorescent lamps and LED modules for the light-technical parameters, luminous intensity, radiation spectrum and settling time of light sources are evaluated and compared. The second chapter is solved by using ReluxPro, which explores the impact on the lighting and the brightness of the room layout SA 5.10 while using various light sources. In conclusion, there is an economic aspect of linear fluorescent lamps and LED modules analyzed. Results from the program ReluxPro are continuously compared with real measured values.

Multi-Storey Administrative Building
Tomeš, Martin ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The diploma thesis deals with the design of the administrative building from steel S420, S355 and concrete C25 / 30 with reinforcement made of steel B500B. The office building is a column-type with reinforced concrete ceiling. The building is equipped with a footbridge on the 10th floor. Two variants have been elaborated. Both of them were calculated in the program Scia Engineer. The winning variant is processed in detail.

Reactive power compensation of electrothermal devices
Tomeš, Martin ; Paar, Martin (referee) ; Lázničková, Ilona (advisor)
The work deals with reactive-power compensation (power factor correction = PFC) in practice. The theoretical part describes the basic concepts of power factor correction, reasons for the PFC, and the ways of the PFC, eventually a sanction for a breach of rated power factor. Attention is given to basic partition of the PFC and compensation devices which are capacitors and detuning reactors. The practical part is focused on the PFC analysis for a concrete customer where the central compensation is projected. The practical part is also focused on a detuned power factor correction which is often used by reason of increases in number of nonlinear loads nowadays.
