Power supply of electrostatic separator
Broďák, Kamil ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
The diploma thesis focuses on the problems of electric power precipitators. Due to their current dominant position, the work concentrates on the sources of single phase transformers operating at the frequency of 50 Hz controlled by thyristors. The first part describes the electrostatic precipitator and its principle. This is followed by a brief insight into the proposal for an electrostatic precipitator. The work also explains the high voltage source that is divided into a transformer with a rectifier and into a control box with power circuits and control circuits that provide the power supplied by a transformer. The work also offers an explanation of the HV source system that operates at different conditions. The last part suggests a proposal for cooling cabinet including thyristors, for power line control box resources, for a supply line and a line to the transformer.

Bártová, Karolína ; Panská, Šárka (advisor) ; Hájková, Jana (referee)
The bachelor thesis will focus on rescue and assistance in selected elements of artistic gymnastics during physical education classes at a chosen secondary school. The main objective of the thesis is to assess the current utilization of rescue and assistance in the selected elements of artistic gymnastics. The research methods used in the thesis were observation and questionnaire survey. Based on the evaluation of observations and data analysis from the questionnaires, it was found that the current level of rescue and assistance during gymnastics exercises in physical education classes is inadequate in some cases, and in some instances, i tis completely lacking, with only a small percentage if teachers possessing knowledge and skills to properly provide rescue and assistance. Key words: Artistic gymnastics, assistance, rescue, floor exercise, horizontal bar, vault.

Proposal of an intervention program for the development of speed preconditions for gymnasts of younger school age
Mejzrová, Adéla ; Kašparová, Alena (advisor) ; Novotná, Viléma (referee)
Characteristics: This thesis deals with women's artistic gymnastics, and especially the speed training of young gymnasts, for whom vault is one of the key competitive event of competitive performance. The thesis also contains the issue of motor skills, especially speed skills and characteristics of younger school age. The bachelor thesis presents a proposal for an intervention program developing speed requirements for a selected group of gymnasts. The dynamics of run-up is one of the prerequisites for a successful jump in gymnastics. Thanks to the run-up, the gymnast gains the necessary energy to perform the jump, and therefore it is necessary to develop the speed assumptions in early childhood. Goal: The main goal of the bachelor thesis is a literature research for the design of a battery of recommended exercises and an intervention program focused on the development of speed prerequisites for gymnasts of younger school age. The battery of recommended exercises and intervention program are created not only on the basis of a literary research, but also established criteria, such as age, skill level and competition discipline. The thesis can be an inspiration for teachers and coaches of other sport specializations. The bachelor thesis forms a theoretical basis for the planned research measurement of...
