Acceleration and motion of upper limbs
Novotný, Adam ; Kolář, Radim (referee) ; Kolářová, Jana (advisor)
Purpose of this work is mainly the description of electrical plots in skeletal muscles and secondarily experimental verification and description of methods connected with measuring and evaulating biosignals. The theoretical presentation of muscle physiology facts is supplemented with an experiment using pair t-test, which describes procedures leading to evaluating particular hypotheses (the measured muscle is biceps brachii). In this work, the biosignal is an EMG signal, thus the electrical activity of muscle. Therefore, the main objective of this work is not only about using EMG as an examination method, but also about showing a complex view at the recording, processing and evaluating of EMG signal. These facts are supplemented with programm application which is showing the way working with EMG signals and also the possibilities of algorithm development in such signals.

Creation and verification of specialized training sets for fire sport
VORÁČKOVÁ, Veronika
The aim of this diploma thesis was to create and confirm a set of specialised trainings for fire sport. There were adults older than 18 and children and teenagers aged 8-17 in tested groups for this thesis. The firefighters were from the Volunteer Fire Department Omlenice. A quasi-experiment method was used in this thesis. Entrance testing was performed at the beginning of winter training and after ten specialised trainings, final testing was performed. The testing was implemented through Denisiuk test, which was focused on velocity skills, explosive power, power skills, endurance and agility skills. Obtained results were recorded in graphs and charts and evaluated. Through the paired t-test, statistical significance was verified and through Cohen´s d, practical significance was verified. The hypotheses were confirmed at most of the tests because these were statistically significant with a mild or medium effects, however some had to be eliminated at tests with statistically insignificant results.

Hodnocení finančního zdraví podniku z pohledu účetnictví na případu zemědělství
NÝVLTOVÁ, Kristýna
The dissertation deals with the accounting aspects of assessing the financial health of a company with a focus on agriculture. The main objective of this study is to assess individual methods designed to evaluate the financial health of a company, to determine their sensitivity to risk data in accounting. The study is focused on the field of agriculture mainly as a result of knowledge about the difficult process of compiling and using agricultural accounting. Agriculture fall within the primary sector of the economy, is very important for landscaping and a lot of subsidies flow from the budget of state and the European Union. Due to the specifics and stated problematic areas, which cannot be fully captured by legislation, incomplete or distorted information is transmitted, being also transferred to the methods of the financial health assessment of the company. Attention is also paid to the influence of legislative changes on the values in accounting as well as creative accounting. Following the findings from the theoretical basis, the application part analyses the impact of different accounting solutions on the financial statements. A paired t-test, used for the analysis, was preceded by data normality testing using the histogram and Shapiro-Wilk test. According to these tests, statistically significant differences were found com-paring the current method of accounting used for investment subsidies and leases with the IFRS accounting, between the accounting of changes in inventories and capitalization before and after 1 January 2016, and in land valuation using historical cost and market price. All these areas influence the values of all the analysed methods of financial health assessment. Only the CH-index showed no statistically significant difference in land valuation and accounting solution of inventory activation and changes. Furthermore, the reliability and controllability of the selected methods used for the evaluation of financial health in the field of agriculture is assessed. According to the results, none of the evaluated models can be used in its original variant, but it is possible to use them to compare the company with similar enterprises or over time thanks to the proven dependence of partial indicators and even the whole models on the productivity. Another type of analysis is designed to determine the indicators that have a statistically significant impact on the actual financial situation of businesses. The method of generalized linear models - multinomial linear regression - is used for this test. To determine whether an enterprise is at risk or not, it would be possible to use the stock / income and short-term liabilities / income indicators, and the cash flow / assets indicator to determine the type of threat.
