Path Planning for Robot Formations
Hornáček, Zdenko ; Uhlíř, Václav (referee) ; Rozman, Jaroslav (advisor)
Robotics has been experiencing great development in recent years. This development is due to constant technical progress and the effort to develop increasingly robust robots and to further develop co-operating groups of robots. These co-operating groups (robot formations) have many areas of use ranging from environmental mapping to search and rescue missions. This bachelor thesis deals with the design of the path planning algorithm for robot formations. It uses the already existing planning algorithm for single robot - the Dijkstra algorithm. Based on the path computed by this algorithm, the proposed algorithm will calculate the path for each robot so as to maintain the shape of the formation during its move to the goal.

Effect of glass fibers in the lead-acid batteries for hybrid electric vehicles
Klojda, Viktor ; Tošer, Pavel (referee) ; Bača, Petr (advisor)
Master´s thesis deals with the utilization of lead-acid accumulators in hybrid electric vehicle regime. It describes the side effects known as PCL, generated during PSOC regime and connected with the length of the battery lifespan. One possibility how to eliminate these effects, is the use of additives in active mass of the negative electrode, in the form of glass fibres. The project provides the parametres and reactions of additive, that have lead to the improvement of battery properties. The purpose of this thesis is to verify the positive effect of the aditive on the lifespan of the lead-acid accumulator.

Lead-acid battery formation
Hlaváč, Pavel ; Tošer, Pavel (referee) ; Vaculík, Sebastian (advisor)
This bachelor project deals with the pulse charging of lead-acid batteries and ways of formation of electrodes so that the new batteries can constantly offer high performance and efficiency for its life. The work is an attempt to compare and determine whether the formation of different charging modes will not have a major impact on the quality of a formed battery. The formation of the different modes uses both the pulse and continuous charging. Everything is tested on four manufactured articles. The production of positive electrode and formation of accumulator is processed in various chapters of my project at our workplace.

The reflection of priest celibacy in contemporary theology and culture.
Švecová, Petra ; Fošum, Jan (advisor) ; Bouma, David (referee)
Reflection of priest celibacy in contemporary theology and culture Abstract The Bachelor's thesis describes the reflection of priest celibacy in contemporary theology and culture. This topic is part of a wider discussion about human sexuality in theology and history. A part of the thesis includes a historical review which is connected to the current systematic reflection. The identity of priests and the way of speaking about celibacy and priesthood in present theology is very different, the text examines the experience of sexual abuse in the church. The thesis takes notice of the different approaches and possible consequences of them, e.g. the image of women in texts that discuss the celibate way of life. It also observes the possibility of a better connection to the present culture and social sciences. Keywords celibacy, priesthood identity, theological reflection of celibacy in history and today, celibacy and relationship to women

Analysis of power plays in Czech republic U18 for the last three World Championship (2018, 2019, 2021)
Brož, Jaroslav ; Novák, Dominik (advisor) ; Vojta, Zdeněk (referee)
Title: Analysis of power plays in Czech republic U18 for the last three World Championship (2018, 2019, 2021) Objectives: The aim of this bachelor thesis will be a detailed analysis of the goals scored from numerical superiority at the U18 World Championship in 2018, 2019 and 2021. The first sub-objective is to determine the positives and negatives of the Czech national team's power plays at these World Championships. The second sub-objective is to compare the Czech Republic's power plays against the top two ranked teams from all World Cups. Methods: The analysis was conducted in the form of indirect observation. Using video recordings, 71 power play goals scored in 43 matches from three World Championships in 2018, 2019 and 2021 were observed. The teams observed were always the Czech Republic together with the finalists of these three World Championships. The goals were then recorded in the created record sheets and analysed. Results: The analysis included the shooting area, shooting location, the formation used to score the goal and the type of shooting. The results show that the most common shooting space was in front of the goal, which was seen in 26,76 % of power play goals. The most exploited shot of the World Championship was the cross-ice shot with a share of 63,38 %, which was most often...

Adaptive formations for virtual agents
Švagerka, Michal ; Plch, Tomáš (advisor) ; Čermák, Miroslav (referee)
There is a growing number of virtual agents in today's virtual worlds. This is directly related to the need of coordinating their behavior and movement. In this work we design algorithms to maintain desired formation of agents while moving through difficult terrain. The methods we study should maintain the requirements of the formation as well as traverse along various obstacles. We then use an arbitrary fitness function to compare the performance of these methods on typical scenarios.

Coordinated pathfinding with formations
Obrázek, Václav ; Surynek, Pavel (advisor) ; Balyo, Tomáš (referee)
The topic of cooperative pathfinding with the extension of formations is addressed in this thesis. The problem of cooperative pathfinding with formations was formally defined and a new scalable hierarchical modular solving algorithm named APriCA was introduced and implemented. For testing and benchmarking purposes an environment called ChessWars was developed. In order to measure the quality of maintaining formations we introduced a new quantity named "fragmentation". The APriCA algorithm performed better than external domain independent planners such as LPG, Blackbox and SASE in all aspects. In comparison with the LRA* algorithm the solutions found by APriCA were of better quality and with certain parameters settings were found faster.
