Time evolution of velocity distribution in the specific area of the calibration channel
Kosík, Ondřej ; Žoužela, Michal (referee) ; Zubík, Pavel (advisor)
This bachelor thesis deals with the verification and determination of the degree of reliability of the calibration track. The mean speed values for individual reference speeds, which ranged from 0,0507-1,4036 m•s-1, were measured by LDA. With increasing speed, the mean square deviation also increased, reaching the highest value of 0,0034 m•s-1. The percentage deviation, which is core value for the given measurement, on the other hand, changed inversely with respect to the mean values of the speed and its values ranged from 0,242-0,473 %.

Reinforced concrete structure of a department store
Košík, Ondřej ; Požár, Michal (referee) ; Šulák, Pavel (advisor)
The bachelor thesis deals with the design and assessment of main parts of the carried reinforced concrete structure of a department store. The aim of the thesis was to design and evaluate the reinforced concrete structure of the ceiling slab, pillar, staircase and the wall. A graphical documentation of selected elements is also a part of the thesis. The calculation of internal forces was performed in a computational program SCIA Engineer 17, subsequently this calculation was verified by a manual method. The construction is designed according to the ČSN EN standards.

Comparison of speed measurement by hydrometric propeller and laser anemometer
Kosík, Ondřej ; Haluza,, Miloslav (referee) ; Zubík, Pavel (advisor)
This final thesis deals primarily with the comparison of two calibration approaches. It determines the degree of mutual agreement and tries to answer the reasons of their deviations. This agreement was measured by the LDA method. It was found that the calibration approach based on the reference framework of values of the previous bachelor thesis differs systematically from the calibration using calibration equations obtained from certified laboratories by -2 %. The causes of this deviation were investigated using LDA and PIV. Although a significant number of measurements were performed, all tested hypotheses were refuted and therefore it was not possible to determine their cause.

Precast concrete frame construction
Košík, Ondřej ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
The aim of the final thesis is to design and structural design report of selected elements of prefabricated storage hall. Processing of foundation drawing, element composition and for each designed element formwork drawing and reinforcement. It is a single-storey hall, where the main structural system consists of a transversal frame columns and prestressed girder. In this final thesis I designed and structural assessed prestressed girder, reinforced concrete purlin, roof bracing, column, grade beam and foundation pad. The calculation software Scia Engineer is used to calculate the effects of internal forces. The results are compared using a simplified method. The design and structural assessment are made according to valide standards. The designed construction complies with the limit state of ultimate and serviceability.
