Quality of Life of MOBA Video Game Players: Questionnaire Survey
Bártek, Jonáš- Jan ; Vondráčková, Petra (advisor) ; Vacek, Jaroslav (referee)
Background: Gaming is becoming more of a popular leisure time activity. "Multiplayer Online Battle Arena" (MOBA) games have become one of the most played video games in 2022, MOBA games became even more popular than one of the most reaserched genre of games, "Massively Multiplayer Online Role Playing Games" (MMORPGs). Some authors state that MOBA games have the biggest potential for becoming addictive for it's players. However, reaserch does not show the magnitude of playing popular MOBA games on the quality of life of it's players. Objectives: The main goal of this work was to find out the relation between the quality of life and playing MOBA videogames - to figure out how the quality of life of MOBA game players differs from the quality of life of standart population, to find out how the quality of life differs according to their potential hazardous gaming or addiction to gaming, and to find out how the quality of life of MOBA games players differs regarding the time spent playing MOBA games. Methods: Respodents filed in a questionnaire, which was accessible on social networks in online communities of MOBA games players. The sample consisted of 571 mainly Czech players of MOBA games with the average age of 21,7 years. The quality of life was measured with SQUALA (Subjective QUAlity of Life...

Geometric Brownian motion in Hilbert space
Bártek, Jan ; Maslowski, Bohdan (advisor) ; Beneš, Viktor (referee)
The present work describes the relation between solutions of a special kind of nonlinear stochastic partial differential equation with multiplicative noise, driven by fractional Brownian motion (fBm), and the solutions of deterministic version of this equation. Solution of the stochastic equation is given explicitly by means of solution to the deterministic equation and trajectories of fBm. The geometric fractional Brownian motion plays an important role here. The solutions are considered both in strong and weak sense. Stochastic integral wrt. fBm with Hurst index H can be defined in various ways. Here we consider a Stratonovich type integral for H > 1/2. The results obtained are used for the study of properties of solution of stochastic porous media equation - the expected value of total mass of the solution and the long-time behaviour of the solution.

Coupon's collector problem
Nývltová, Veronika ; Pawlas, Zbyněk (advisor) ; Bártek, Jan (referee)
In the presented work we are looking for the answer to the question how many purchases must be made for obtaining a collection of cards. As a collection we understand all types of cards, which are packaged with products or we consider a collection of chosen types of these cards. First it is assumed that all cards are uniformly distributed. The number of required purchases is random and we derive its mean value, variance and probability distribution. We study limit behaviour when the number of types of cards is going to infinity. We are looking for the answer to the same question in the case of collecting several collections of cards at the same time. These collections could be complete or incomplete. In the case that cards are not uniformly distributed we describe mean value and variance of the number of purchases necessary for acquiring several collections of cards.

Sales support on the Internet
Bartek, Jan ; Sedláček, Jiří (advisor) ; Slaba, Jiří (referee)
This bachelor's thesis deals with the sales support on the Internet and it's single instruments. Theses is divided into two main parts. Theoretical part of this bachelor's thesis describes all instruments of sales support on the internet and puts them into perspective with real life practical examples. Second part, of this theses deals with the new trend in marketing, which is sales support on social sites via "new age celebrities" - youtubers. This part of theses includes a controlled experiment, which will compare the effectiveness of sales support campaign carried out via youtubers with a classical PPC campaign.
