Overhead travelling crane 18 t x 28 m
Veselý, Vít ; Špička, Jiří (referee) ; Mynář, Břetislav (advisor)
This diploma thesis deals with examination of a steel construction of an overhead travelling crane with a span of 28 metres, lifting capacity of 18 tons and maximum lifting height of 6.5 metres. The crane will be installed in a hall. Solution of this project contains calculation of load and examination of the crane construction with fatigue under the Czech standard ČSN 27 0103 and the European standard EN 13001 and comparison of calculations under both of the technical norms.

Electrical system designs of the hotel complex with wellness
Veselý, Vít ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
The bachelor thesis deals with the implementation of the technical solution - the distribution of the electrical network of the hotel with wellness. The theoretical part of the thesis presents an analysis of the basic elements used for the design of substations and busbars and introduces the basic computational apparatus for sizing transformers and lines. The practical part presents the various technical solutions for the design of the electrical network of the site, specifically addressing the design of low voltage (LV) cable lines for two variants providing 100 % backup of the electrical supply to the site and two other variants providing 50 % backup. In addition to the technical design of the individual options, the work also presents for each option their detailed financial budgets, including their overall economic comparison.

Analysis of technique and efficiency of running using Nike Air Zoom Alphafly shoes
Veselý, Vít ; Kovářová, Lenka (advisor) ; Červinka, Pavel (referee)
Title: Analysis of running technique and efficiency when using Nike Air Zoom Alphafly shoes. Objectives: The main goal is to identify possible changes in selected physiological parameters and biomechanics of running when using Nike Air Zoom Alphafly shoes compared to standard running shoes. Methods: A 3D treadmill (H/P Cosmos Gaitway II S, Germany) was used in the analysis of running biomechanics. For the analysis of physiological parameters, the Metalyzer device was used within the spiroergometric examination of the run. The Borg scale was used to analyze the subjective assessment of the load. A paired T-test of Excel software was used to process the results. Results: The results of the work partially show a change in the biomechanics of running. A statistically significant difference was recorded at all speeds (15 km/h, 18 km/h, 21 km/h) in loading rate (p15 = 0,003; p18 = 0,000; p21 = 0,001) and time to impact peak (p15 = 0,017; p18 = 0,022; p21 = 0,003). At a speed of 15 km/h, an additional difference in running cadence (p = 0,044) was noted. The results show a statistically significant change in the economics of running all measured parameters, in oxygen intake converted to kilograms of weight (p = 0,003), minute ventilation (p = 0,000), respiratory rate (p = 0,000), respiratory coefficient (p...

Comparation of the Actual Bike Fitting Systems for olympic distance triathlon (case study)
Veselý, Vít ; Kovářová, Lenka (advisor) ; Šafránek, Jiří (referee)
Title: Comparison of Current Methods of Cycling Set Up for Cycling Olympic triathlon (case study). Objectives:. The main aim of the thesis is to compare the subjective and objective performance of selected fitting settings. Methods: : In our work we compared three methods of cycling setting - theoretical methodology of calculation and individual dynamic methodology of Retül and Guru Fit Bike. We used the objective performance evaluation Spiroergometric stress test. We have rated the performance achieved at the level of aerobic and anaerobic threshold and then compared the maximum achieved parameters. The pedal technique was evaluated using the Wattbike SW. Comparison was performed using percentage points. Subjective assessment was carried out by means of a controlled interview. Results : We found that proband in the subjective evaluation better evaluated the methods of the Guru Fit Bike and Retül compared to the objective rating in which the theoretical method achieved the best results. Keywords: biomechanics, fitting, effectiveness of cycling, pedal technique, spiroergometry.
