Changes of the catecholamins, serotonine and lactate levels during sport climbing on a climbing wall depending on the leader climber's style of belaying
Strnadová, Kateřina ; Vomáčko, Ladislav (advisor) ; Bunc, Václav (referee)
Title: Changes of the catecholamins, serotonine and lactate levels during sport climbing on a climbing wall depending on the leader climber's style of belaying. Goals: The Goal of this thesis is to build on the bachelor thesis and develop its goals. The research is focused on a detection of blood hormonal changes before performance, right after it and after a 15- minute pacification depending on a style of a personal profile and style of belaying of the climbers. Hormonal changes have been compared during the performance on two climbing routes of the same difficulty and different styles of belaying. Methods: The randomized research sample consisted of 10 women, climbers, who climbed two routes using the OS (on sight) style on the level of maximum effort. One of the routes was climbed with clipping in protection points against the second route, which was climbed without protection points. The research was performed using a blood collection from v. brachialis and spinning off the blood plasma of the collected blood. Lactate was determined on Siemens Adria 1800 in a routine laboratory, serotonine was determined using LS-MS/MS with a gradient elution. Catecholamines were determined using LS-MS/MS with an isocratic elution. The survey composed of three psychological questionnaires (DMV, RCAI, Eysenck's...

Analysis of foot arch structure in female sports and fitness aerobics competitors at different competition levels
Stará, Nicol ; Hájková, Jana (advisor) ; Jandová, Soňa (referee)
This thesis focuses on the foot arch condition in female sports and fitness aerobics competitors at different competition levels. Our aim is to analyze the condition of the longitudinal plantar arch based on plantographic measurements in a group of female athletes differing in performance and competition category. The work consists of two parts. The theoretical part deals with the description of sports and fitness aerobics by its definition and rules, then it describes the anatomy of the leg, the deformities of the plantar arch and last but not least the methods of plantogram evaluation. The practical part of the thesis deals with the analysis of the foot arch structure in selected female athletes at different performance levels. Specifically, in female athletes of the first performance class, where the number of probands measured totalled 44, and in female athletes of the second performance class, where 46 probands were measured. Subsequently, the total population (N=90) was compared to the general sporting population. The practical part of the study included additional questions for the athletes in the form of a questionnaire regarding the duration of participation in sports aerobics and fitness, performance class, frequency of training blocks, special exercises for the foot arch and the use of...

Design of a torque vectoring control system for a Formula student vehicle
Gadas, Petr ; Blaťák, Ondřej (referee) ; Míša, Jiří (advisor)
Tato diplomová práce se zabývá problematikou zvýšení výkonu vozidla při jízdě zatáčkou pomocí aktivního řízení hnacího momentu závodního vozu kategorie Formule Student. Náplní práce je návrh, simulace a následně testování algoritmu, který na základě zvolených parametrů řídí rozdělení momentu na hnané nápravě, aby bylo dosaženo optimálního stáčení vozidla pří zatáčení. Systém byl navržen na základě cíleného dynamického chování vozu při průjezdu zatáčkou. Pomocí virtuálního prostředí byly obdrženy simulační klíčové výsledky vlivu na chování vozidla, které byly následně validovány testováním na trati. Celkovým cílem práce bylo navýšení jízdní rychlosti a kontroly and vozidlem během zatáčení, s výsledkem snížení jízdního času na trati.

Automation of the calibration process
Mařas, Michael ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
This master thesis deals with the automation of the calibration process at the workplace for calibration of electronic power meters and the description of the method of evaluation of calibration results. The paper analyses the calibration workstation and the manual method of calibration performed by the calibration laboratory staff. Furthermore, proposals for automating the manual method of calibration and a description of the implementation of a program for automating this process are given. Subsequently, the uncertainty analysis is described in the paper. In this section, the uncertainty analysis according to the GUM method and the subsequent calculation of these uncertainties are presented. The correctness of the calculation of uncertainties according to the GUM method is verified by the Monte Carlo method. In the last part of the work, the method of evaluation of the calibration results according to ILAC-G8:09/2019 is described and the form of the calibration protocol is described.

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Uncertainty Calculation by the Monte Carlo Method
Kósa, Valentin ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This bachelor’s diploma thesis deals with the measurement inaccuracies. Various types of uncertainty, methods, their specifications and ways of their recording are described. Next, Monte Carlo method and its application are introduced to the reader. Next, both methods described are applied: calculation of accuracy using uncertainty – GUM method and calculation of accuracy using Monte Carlo method. The methods are applied in measurements of DC current at resistive load with different meters.
