The Peak and the Territory
Mlynarčík, Štefan ; Smetana, Matěj (referee) ; Rathouský, Luděk (advisor)
The thesis is focused on symbolic revision of altitudes and border points of Tatra peaks. The subtle gesture disturbs exact and unambiguous textbook perception of a peak´s height. The thesis is happening on the given summits, the material used on their „growth“ and „transfer“ originates exclusively from immediate surroundings. The period of new summit´s existence is exposed to various weather conditions, eventualy to human factor, thus we can consider it as undetermined in terms of time. The issue consists of 5 video documentations of actions on the given Tatra peaks. The thesis is not exhausted by this. On the contrary, it promises spontaneous long-termed continuation.

The influence of cobalt additive on parameters of positive electrode for Ni-Cd accumulators
Svoboda, Michal ; Svoboda, Vít (referee) ; Špičák, Petr (advisor)
The Master´s thesis deals with description of the influence of cobalt additive on positive electrode parameters for Ni-Cd accumulators. Trough the use of Electrochemical Quartz Crystal Microbalance are analysed the effects which decline effective life of positive electrode during accelerated cycling. Theoretical part describes important characteristics of Ni-Cd accumulators, the working principle and effects which are in progress on positive electrode during cycling. The next part deals with description of system EQCM and the pricnciples of doping active mass with cobalt additive. Practical part consists of EQCM system calibration and electrochemical measurements. The principal aim is detection of the influence of cobalt additve on active mass during cycling in different electrolytes. From the results of measurements is set the optimal amount of cobalt additive.
