Study of correlations of cosmic ray showers detected by the CZELTA detection network and gamma-ray bursts
Hubík, Jan ; Smolek, Karel (advisor) ; Suk, Michal (referee)
The origin of high energy cosmic rays is still unknown. High energy cosmic rays can be associated with high energy gamma ray bursts. In the presented work we briefly summarize subject of cosmic rays and gamma ray bursts, including their detection methods. Using statistic methods we study time and directional correlations of cosmic ray showers measured by detection array CZELTA with gamma ray bursts detected by satellite experiments. Presented work provides detailed description of used analysis methodology. We were unable to demonstrate link between described phenomena.

Player Skill Rating for Games with Random Matchmaking
Hubík, Jan ; Červinka, Michal (advisor) ; Matoušek, Jindřich (referee)
Traditional skill ratings are not suitable for new types of games. We developed a general skill rating framework for games which do not discriminate players based on their skill. This class of games is widely present in the world. We use Bayesian statistics to convert aggregate data about the player's performance to a percentile rank describing his skill. The system is applicable to both single-player and multiplayer games with binary and non-binary endings. The rating formulas do not contain any arbitrary constants. We have tested the system in simulations and on real game data, and we outline its possible applications.

Man and nature in the age of technics
Hubík, Jan ; Nitsche, Martin (advisor) ; Benyovszky, Ladislav (referee)
In our thesis we focus on a relationship between man and nature from a view oh thinking of Martin Heidegger. In the field of his fundamental ontology we try to grasp a difference between being of man a being of nature. This difference is based on the apparentness of beings as beings in the whole. In his work Being and Time Heidegger thinks the world within the structure being-in-world. The being of nature is in this work think in connection with basic ontological character of beings, that we encouter in our world. The nature is uncovered on the basis of the ready-to-hand. This conception leads to the problém of antropocentrism, that follows from the structure of Being and Time and fundamental ontology. Therefore we then focus on the turn in Heideggers thinking, that is articulated in the later maxim "to think being directly out of being itslef". In later works from 50's Heidegger thinks human being as dwelling on the earth in connection with a theme of devastation of the earth. These later works also deals with the technics. Its essence Heidegger names as Ge-stell. It is technology that determine our relationship to nature.
