This diploma thesis deals with battery charging. The thesis describes qualities and possi-bilities of lithium battery charging. The charger is independent on the input voltage and recharges batteries carefully. Due to a careful recharging process it is needed to measure the voltage at various cells of the battery and then balance this voltage. Since the charger is to be implemented in a robot, it is needed to switch the operation from an external source and the battery. The first part of the project deals with qualities of batteries and the way of their recharging. In the second part I design an individual blocks charger. In the third part I deal with a communication with a computer charger and data visualization. And in the last part I designed a program for the charger.

The number of batteries, namely accumulators, is growing. Consequently, their take-away and a need of recyclation is increasing too. It is thus necessary to find a suitable way to their optimalization that can lead to the establishment of new waste collection machineries. This study deals with the data analysis by ECOBAT s.r.o. company, data processing and a model construction (in five different versions). The output of the diploma thesis is a model of the batteries collection enabling closer look on take-away routes, The model is based on the distances of take-away routes based on a principle of the utility areas and a role of a transport. The data are obtained from ArcGIS 10.5 and subsequently handled in Microsoft Excel. The outputs are the map schemes issuing from five different versions. The first one is showing the current situation, The other one is showing the version of treating units in three largest towns of the Czechia, the third one treating units in all the towns with above 100 000 inhabitants. The forth on eis showing a possibility to have a collection point in each of the county seats. The last one has the same location, but the threating units have higher capacities. The model is general, there is therefore a possibility of using it for other similar situations.

The number of batteries and especially accumulators, which we use, is growing every time and collection with take-away is growing too. Now it is absolutelly important look for a way to optimalization, which can be for example builing new processing equipment. Graduation thesis deal with data analysis from battery collection, data processing and building a data model in four variants. Graduation thesis work with number of battery and accumulators in czech households and bring answer to question "How many batteries we have got approximately in our households?" Output is processing questionary about Research of battery in households,which is used in next work. The main output is data model.Model work with distance of take-way route on principe Service area and Transportation theory. Data are obtained by ArcGIS and processed in Excel. The output are map schematics which are based from four studies. First study shows present state, next shows battery factory in another capital town in regions of the Czech Republic. Third shows variant battery factories in three biggest cities and fourth battery factory in all czech cities, that have 100 000 residents. The best combinations is probably study with three biggest cities, because in this study is saving 50 % of costs and withal it is not necessary build many...

Theme: The comparison of tests parameters of Czech and world javelin throwers Aim: To compare test batteries of Czech and world javelin throwers from the past to the present time. To characterize individual javelin schools in the world and point to the differences between these schools and compare them with a Czech javelin school. Methods: Our work is mainly focused on the method of comparison. We use this method in result to answer some scientific questions. It was compared 25 elite javelin throwers in total with their average performance 88,84m. For data analysis we used basic descriptive statistics to compare differences between Czech and world javelin throwers. Further, it was also used for the method of research focused on searching of professional publications, training diaries and we also used the method of interview/dialogs between their trainers and competitors to characterize javelin schools and get tests parameters. Results: We can see from gathered results that the Czech javelin school took a different way to achieve this sport performance. That fact was shown in test results. The results of general test batteries of world javelin throwers were higher/better in average than the results of Czech javelin throwers. But the results of special test batteries of Czech javelin throwers were...

This thesis focuses on testing the motoric assumptions of junior category tennis players in certain sport games. The aim of this thesis is to compare the results of the motoric test regarding to three tennis players of various performance levels in chosen sport games. Thus define the substantive significance and specificity of each test towards tennis. The assumptions in the theoretical part are based on my Bachelor thesis. In said thesis I am dealing with the characteristics of tennis, the structure of sport performance, the factors which determine the sport efficiency in tennis and most importantly on physical condition. The theoretical part is also widened by newly acquired knowledge. In the result part, based on the comparison of the three tennis players of different performance levels, the substantive significance of the test in tennis was stated. Subsequently we present the results of our test subjects in selected sport games. Using the comparative analysis the differences of motoric assumptions in various sport games are stated.

The specificity was confirmed for hexagon, spider and the test of endurance suited for tennis. The...

Title: Testing of a movement activity quality of Mělník female students. Objectives: The aim of the work is to evaluate the movement mode and the movement activity quality of adolescent girls and in addition we will evaluate their body composition with the help of BMI and caliperation method. Methods: We have worked out the thesis on the base of studying literary sources. 32 adolescent girls aged from 17 to 18 years studying the Secondary Grammar school of Jan Palach made up the examined file, their average body height was 170, 2 ± 6 cm, body weight 63,3 ± 8,8 kilograms. The body composition was assessed with the help of BMI and caliperation method. Then we measured the amount of walked footsteps a day with the help of Omron pedometer and on the base of found out results we evaluated the movement mode of female students. Finally we evaluated each student's movement activity quality with the help of test set Unifittest 6-60. All the measuring and testing took place in standardized conditions with minimization of external impacts to provide the objectivity of measuring. Results: It has been clear from the results of somatic measuring of body heights and weights that in comparison with the average of girls of the same age in the Czech Republic our examined file is 2,7 cm taller and 4,8 kg heavier in...
