Random walks on networks, hitting times and cover times
Havránek, Jiří ; Prokešová, Michaela (advisor) ; Večeř, Jan (referee)
This thesis studies the cover time of random walks on finite connected graphs. Work contains the derivation of upper and lower estimates of cover time which allows us to focus on hitting time instead of cover time. We show that in some cases the problem of searching for the hitting time can be further simplified with the usage of the electrical networks, which can provide a different model for considered random walks and can help finding the hitting time through the effective resistance between some vertices. This procedure is used to find the upper and lower bounds for specific families of structures, which ilustrates that in some cases the bounds are asymptotically very tight and in other cases they give poor results. 1

Havránek, Jiří ; Szobi, Pavel (advisor) ; Chalupecký, Petr (referee)
In connection with the gradual release of the Cuban communistic regime it comes to gradual canceling of barriers and blockades that some countries imposed on the Republic of Cuba. Thanks to the canceling of these barriers it comes to opening of a new market that has been in the past one of the great areas for the international trade of Czechoslovakia. The aim of this work is to analyze the statistic of foreign trade between Czechoslovakia and Cuba in the 70s of 20th century, especially than after the Republic of Cuba entered the CMEA. Specifically there are examined different commodities that have belonged to the most important trade goods in the given period. The method of examination is the analysis of import and export between Czechoslovakia and Cuba and comparison of these statistics with the summary statistics of Czechoslovakian foreign trade. The conclusion of this work summarizes the results of analysis of cooperation of the above mentioned countries and evaluates the impact of entering of Cuba into the CMEA.
