Static verification and alternative design of steel structure of winter sport stadium in Znojmo
Strnadlová, Kateřina ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis is the recalculation and alternative construction design of roofing winter stadium in Znojmo. The building has a rectangular plan with dimensions of 84 x 63 m. The existing roof structure consists of truss purlins and main truss with parabolic chord, which are carried out by a pair of steel arch with a span of 84 m. The new design is processed in two options. The first option is the structure formed by triangular arch truss girder with truss purlins. The second option is a steel lamellar vault formed by vierendeel beams. After evaluating the design options was for a detailed solution chosen the first option.

Static verification and variant design of roof structure of winter sport stadium in Znojmo city
Kovář, Jindřich ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of the thesis is the conversion and alternative proposals for the existing steel structure roofing winter stadium in Znojmo. The building has a rectangular shape with dimensions of 84 x 63 m Roof truss structure is formed purlins and trusses girlandovými, vynášenými two steel arches with a span of 84 m variant solution is full board and reduced lattice truss plate. After evaluating both solutions was chosen the first option, which was subsequently designed and assessed according to applicable standards. Truss plate is designed on the original footprint supported the original concrete bearing walls. Eye lattice plate is a square with sides of length 3.5 mA at 3 m Joints are designed truss balls and anchoring pin.

Steel structures of boiler and engine rooms
Krompolc, František ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
A steel construction, divided into two parts, was designed for the building object of a production block of a bio power plant. The two parts separate the boiler room and the engine room. Due to the specific load caused by the operation equipment, also several plateaus, consoles, footbridges and technological constructions were designed. A system of principal pillars HEB, transversely frame-connected with plane solid girders IPE, forms the hall construction. Pillars in rows 1 and 4 are rigidly jointed to foundations. A bearing structure of the roof deck is imposed on the girders. It is composed of a system of purlins – rolled profiles type UPE. The rigidity of the roof is secured by horizontal bracing between the purlins. The construction of the boiler room is attached to the construction of the engine room, which is formed of frame-connected principal pillars HEB in rows 4,7 and 8. The roof truss IPE is designed for 12 900 mm span between rows 4 and 7 and for 4 800 mm between rows 7 and 8. The spatial rigidity of the structure is not only secured by the rigid connection of pillars and foundation combined with the frame-connected roof rungs. It is mainly maintained thanks to the system of vertical wall bracings interacting with the horizontal bracing of the roof. Between the pillar rows B, C, D, E, F and G and 8 to 9 a construction of a substation is attached. In the engine room is situated technological structure. The construction is formed by supporting frames consisting of pillars type HEA, rungs type IPE and HEA and vertical bracing of rolled profiles. Pillars type HEA are connected to foundation using articulated connection. The rigidity of the structure is secured both ways by vertical bracing and by the connection of the plateau beams with the hall girders.

Roof structure of construction for social purposes
Bašista, Ján ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Gamut mapping algorithms in color management
Svoboda, Jan ; Říha, Kamil (referee) ; Rajmic, Pavel (advisor)
The thesis deals with colors - their representation in digital devices and how to provide the best color preservation accross different devices. In the first part of the work, the knowledge of colors and human vision is briefly summarized. Then color models and color spaces are elaborated, mainly those device independent. Spectrum of colors viewable or printable on a device - the gamut - is different for every device and there's a need of precise reproduction or record of color. That's why the system of color management is described further and especially the gamut mapping approaches and algorithms are mentioned. In the second part of the work, the implementation of how two algorithms of color gamut mapping (HPMINDE, SCLIP) can be implemented in MATLAB is described. In the third and last part of the work, the results of implemented algorithms are presented and discussed. These results are compared to results of commonly used color gamut mapping technique (Adobe Photoshop).
