Compensation of missing air resistance while running on a treadmill
Švejdová, Monika ; Pokorný, Jan (advisor) ; Procházka, Michal (referee)
This work is focused on compensation of missing air resistance while running on a treadmill. The aim is to find the possibilities of compensation and its verification by a slight inclination of the treadmill. For the verification, we used the heart rate values of (6) probands obtained while running on a treadmill with different grade and while outdoor running at the same speed. The output of this thesis is the determination of the treadmill grade compensation at speed of 10,5 km/h and 13,5 km/h.
Hydromorphology as a component part of ecological condition of water bodies
Kujanová, Kateřina ; Matoušková, Milada (advisor) ; Lehotský, Milan (referee) ; Pokorný, Jan (referee)
Today, the study of fluvial-morphological processes is focused on evaluating hydromorfological status of streams and on proposing restoration measures. A fundamental prerequisite for assessing the current hydromorphological status of streams is establishing reference conditions for each stream type that serve as a benchmark and represent the target status after restoration. The aim of this thesis is to describe type-specific hydromorphological reference conditions for rivers on the territory of the Czech Republic with the help of determining river types, developing the REFCON method for establishing reference sites and recording characteristics of reference status. The approach to establishing reference sites is based on meeting the criteria of having minimal anthropogenic impact that are first assessed using cartographic data and subsequently verified through field survey. Parameters - altitude, sinuosity, and valley floor slope - for classifying river reaches into types were determined on the basis of the results of statistical methods applied on 3197 river reaches covering the whole territory of the Czech Republic. The classification of river reaches into 9 river types was verified through field survey at 44 sites. Detailed field survey and measurements of characteristics of natural channel...
Comparison of different exercise protocols
Simonianová, Lucie ; Procházka, Michal (advisor) ; Pokorný, Jan (referee)
The aim of this thesis was to summarize current findings about exercise testing. The main goal was to evaluate protocols used in daily practice, their indications and benefits, comparability and parameters that can influence the results. The purpose of the practical part was to compare the maximal values of physiological parameters (heart rate, VO2, minute ventilation, RER, power output and rated perceived exertion) for the two most commonly used protocols for bicycle ergometry tests in the Czech Republic. We compared ramp (1/3W.kg-1 .min-1 ) and step (1W.kg-1 every 3 min) incremental protocols to exhaustion. Thirteen young, healthy and physically fit subjects (9 males and 4 women aged from 20 to 31 years) underwent two tests in separate occasions, during which they performed the protocols in random order. Paired t-test was used to statisticaly analyze the data. We found no statisticaly significant differences in these maximal values except for the exercise test time. We deduced some practical benefits of each protokol from obtained data.
Transport behavior of Dukovany Nuclear Power Plant employees and their motivation to move closer to workplace
Pokorný, Jan ; Jaroš, Václav (advisor) ; Květoň, Viktor (referee)
The bachelor thesis deals with the analysis of transport behavior of eployees of Dukovany Nuclear Power Plant employees and their economic migration. The power plant is situated on the border of the Vysocina Region and the South Moravian Region. It is an important employer in terms of lowering unemployment especially in the Trebic region. The main aims of this bachelor thesis are identification parameters of mobility behavior for the reason of commuting to work and finding the limits of willingness to move closer to the place of work. Identification of transport behavior is mainly based on choosing conveyance, which depends on individual economic conditions. Furthermore, it is linked to the accessibility of an area of person's residence and to the number of his or her family members. The data obtained from the questionnaires survey were analyzed and compared with the literature. At the end of the thesis, all the procedures and results of this work are evaluated and another possible extension of work is proposed. Key words: mobility, transport behavior, accessibility, commuting, economic migration, moving to workplace

Computational modeling of radial hydrodynamic bearings for water machines
Pokorný, Jan ; Šimek,, Jiří (referee) ; Návrat, Tomáš (advisor)
The aim of this thesis is to calculate the stiffness and damping coefficients for radial hydrodynamic bearings. Cylindrical and lemon hydrodynamic bearings are considered. The solution to this problem mainly depends on the hydrodynamic pressure in the bearing. The numerical solution of the Reynolds equation is used to calculate the pressure. The effect of variable viscosity and density of the lubricant due to temperature changes is considered. The static equilibrium position of the journal centre is also solved. The stiffness and damping coefficients are determined using small amplitude journal motions about the equilibrium position. Three methods for determining these coefficients are presented. The outcome of this thesis is an algorithm for the calculation of stiffness and damping coefficients for cylindrical and lemon bearings. Results for lemon bearings are presented and comparison with the commercial software DynRot BR is made. The benefit of this thesis is the creation of an algorithm for the calculation of journal centre equilibrium position, a new way of incorporating the temperature changes in the viscosity and the density of the lubricant, and the modification of a method for calculating stiffness and damping coefficients based on experimental analogy.
A Machine for Automatic Subject Indexing Using ToC
Pokorný, Jan
The technology developed in the National Library of Technology can extract a document’s table of content (TOC), generate relevant keywords, and suggest terms for various classification schemas (UDC, DDC, LCC, Conspectus). It can fully or substantially automate the process of generating subject access, unite it across libraries, and significantly increase accuracy and relevancy compared to subject assignments by non-specialist catalogers. Such increased quality in subject access terms is often seen in the superior subject facets generated by discovery systems and library OPAC advanced search forms.

The influence of the Dance Movement Therapy on psychomotor symptoms of Parkinson's Disease patients
Pokorný, Jan ; Pánek, David (advisor) ; Reckziegelová, Petra (referee)
Title: The influence of the dance movement therapy on psychomotor symptoms of Parkinson's disease patients Objectives: The aim of this thesis is to evaluate the effects of dance movement therapy on postural instability and other motor and non-motor symptomatology of patients with Parkinson's disease. Changes are evaluated by using MDS-UPDRS and Computerized Dynamic Posturography (NeuroCom Smart EquiTest System). Another goal is to provide comprehensive information about dance movement therapy and other dance therapies promoted abroad and to highlight a possibility of their use as a non-pharmacological treatment of Parkinson's disease symptoms. Methods: This pilot study involved eight late onset Parkinson's disease patients at an average age of 68,87±6,69 years. Changes in their postural stability and motor and non-motor symptoms of Parkinson's disease were evaluated after the completion of two months of intensive dance movement therapy. Observed parameters were evaluated by using MDS- UPDRS and the Computerized Dynamic Posturography Smart EquiTest System created by the NeuroCom company, before and after the therapeutic programme. For effective assessment of the therapy, statistical methods (the Student's paired t-test and the Wilcoxon rank sum test) were used along with the rate of clinical...
