Weight control of soft cheese formed on a manual production line
Páral, Marek ; Zemanová, Jana (referee) ; Tomečková, Šárka (advisor)
The thesis deals with the control of the weight of soft cheeses during molding on a manual line. The theoretical part describes the classification of cheeses into groups, the basic characteristics of soft cheeses and their representatives. Furthemore, the whole technology of soft cheese production is processed and the effects on curd formation and factors influencing the weight of cheeses during molding are explained. The theoretical part ends with the basics of statistics for data processing. Basic measuring techniques (dry matter measurement, pH measurement, measurement of temperature and weight) were selected to determine the technological parameters (pH of whey, pH, dry matter and temperature of cheese grain, weight of cheese etc.) to describe the quality of grain in the experimental part of the thesis. The Design of Experiments method was used to find the optimal setting of the molding machine. Three partial experiments were designed and done. Results were verified in real production. The pH of whey was chosen to describe the grain quality. Two factors have been discovered that have a significant effect on the weigh of cheeses during molding, namely the position of the operator during molding and the amount of whey flowing into the forms with the cheese grain. The proposed molding modifications were successfully tested in production and no statistical difference was found between the weight of cheeses formed with the new setting of molding machine.

The examination of the effect of titanium dioxide on the properties of lead-acid batteries
Mlýnek, Martin ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
Despite, considerable advances in technologies for storing electrical energy, lead-acid batteries are still the most widely used these days even it was invented more than a century ago. The functionality remains the same since its invention. Today´s time puts certain pressure on improving some aspects of the functionality like, heat management, charging and discharging speed, capacity and durability etc..... This bachelor´s thesis is based on the last mentioned, Durability,. The work presents the theory of acid batteries with the history of chemical reaction, technological production processes and battery construction. It is followed by a chapter about titanium and titanium dioxide as an addition of negative active mass where all the aspects are being examined in this work.

Manufacturing of castings of a frame of Praga 500 BD motocycle
Vraspír, Kamil ; Haluza, Jakub (referee) ; Roučka, Jaromír (advisor)
The bachelor degree thesis deals with the complete production technology of replica castings of motorcycle frame Praga 500 BD. In the first part of paper is described the historical development of fabric Praga – BD and technical parameters of motorcycle. In the second part is exactly described the production process of model device, comparison of material variants for model producing, forming and preparing metal including casting. Finally the heat treatment and machining castings are described there. The result of work is fabrication of working replica castings of motorcycle frame.

Storage of natural gas in hydrates
Petr, Jan ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
This thesis deals with storage of natural gas in hydrates, forming of hydrate, its transportation and storage. Within the calculation part, three hydrate forming reactors are compared. According to the paramters used in the calculations, a reactor is designed. Basic drawing documentation is also available. The final calculations focus on the nominal evaporation of the storage tank.

Constitutional and Legal Aspects of the Development of the Party System in Chzechoslovakia after 1989
Nosek, Jakub ; Švec, Kamil (advisor) ; Marková, Klára (referee)
This bachelor thesis is focused on democratic transition and forming of pluralist political system at the federal level of Czechoslovak federal state which took its start during so called velvet revolution in November 1989 and meant rejection of previous not competitive model of one party rule which did not accepted real opposition and have only tolerated satellite political parties to Communist party of Czechoslovakia, that did not opposed its monopolist model of government. After fell of the communist regime gradually emerged and crystalized a pluralist party system. First part of this thesis is focused on theory of democratic transition and consolidation subsequently there is space dedicated to the theory of political parties and party systems. Second part is single case study dedicated to description of the Czechoslovak transition with regard to theoretical concepts of the theory of democratic transition and consolidation and through content analysis of relevant laws and constitutional laws are observed emergence and subsequent forming of pluralist party system at the federal level of the Czechoslovak Federative Republic.
