The impact of digital music distribution on the structure of songs and the way they are published
Škopek, Matěj ; Ježková, Tereza (advisor) ; Halada, Jan (referee)
The topic of this thesis is musical compositions and the potential impact of the modern method of their distribution on their structural characteristics, overall form, and method of their release. The work compares two periods, from the years 2005-2010 and 2015-2020, i.e., before and after the rise in popularity of music streaming services such as Spotify. The author's goal is to find a correlation between the changes of parameters selected by him and the development of the music industry and music distribution. In the work, the author first presents the concept of distribution in this broader, general sense of the word and its role as part of the marketing mix. It follows the role of distribution in the context of the music industry and a more detailed description and overall shape of the music market in each of the defined time periods. For each researched year, 10 songs were chosen that ranked at the top of the American music chart Billboard Hot 100. Therefore, the author's research includes 120 recordings. The monitored parameters are the length of the song, its tempo, the location of the first chorus, the total number of choruses, and whether the song was released as a separate single. The author presents five hypotheses that are based on the authors' publications in the field of music. As...

Monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and nordic walking
Škopek, Martin ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Jandová, Soňa (referee)
The Dissertation is concerned with monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and Nordic walking (NW) with focus on adults and by means of electromyography method. Within the process of field testing there were 9 randomly selected individuals at the age of 50 - 60 tested to elicit differences in the motion system. There was an effort to find certain differences within involvement of specific muscle groups in the area of shoulder girdle, pelvic girdle and lower limbs and retrieval of similarities of coordination attributes concerning locomotion at horizontal presented by paradigm of kinesiological content of reflexive crawling according to Vojta's principle. Kinematic analyses was used to discover a difference in involvement of specific muscles between Nordic (v = 5 kph) and regular walking (v = 4, 75 kph) up to 10˚ of ascent. Muscles where their MVC was diagnosed the difference in individual muscle involvement was monitored expressed in percentage. The values found were consequently related to their referential value of MVC and tested by means of Wilcoxon test for dependent selection. Muscles where MVC value was not diagnosed the intraindividual comparative analyses of activation muscle pair similarity was carried out on the grounds of...

Travelling salesman problem and method GENIUS
Škopek, Michal ; Pelikán, Jan (advisor) ; Fábry, Jan (referee)
The target of this thesis is to explain the Travelling Salesman Problem and also create a special program, which will be able to make calculations using the heuristics GENIUS. The Travelling Salesman Problem will be described from two different points of view. The first one is the historical description of the idea of the Travelling Salesman Problem and later will be the problem will be described with some of the very wide number of the calculation methods. For the explanation of the methods, in the thesis there has been chosen some of the algorithms which belong to that methods. The heuristics and also the exact algorithms will be explained. The focus of this thesis is on the heuristics called GENIUS and also in the creation of the program which can calculate it. The program works first with the GENI algorithm and after that it works with US post-optimization algorithm. The program will be described from the point of view of the user and the manual will be written as well. The program will be tested on two different examples and will be compared with the exact algorithm.

Computation of 3D Electrostatic Fields Excited by Thin Conductors
Karban, P. ; Škopek, M. ; Doležel, Ivo
Solution of 3D electric fields in a system of thin charged conductors of general shapes by classical differential methods (FDM, FEM etc.) is extremely difficult due to ignorance of boundary conditions and existence of geomertically incommensurable subdomainswithin the investigated area. Application of integral methods is also complicated because the kernel functions occuring in the first-kind Fredholm equations are intergrable only in 2D and not in 1D.
