The Juno Mission to Jupiter
Gall, Jiří ; Sedláček, Pavel (referee) ; Froehling, Kenneth (advisor)
Semestrální práce je zaměřena na zkoumání planety Jupiter sondou Juno. Jsou zde popsány mise k Jupiteru, které předcházely misi Juno, spolu s jejich dosaženými výsledky. Dále je v této práci popsaná samotná mise Juno se zaměřením na zkoumání vzniku a následného vývoje planety. Je zde popsán průběh mise od startu až po, ještě neuskutečněné, shození sondy do atmosféry planety. Poté jsou popsány konstrukční prvky a subsystémy vesmírné sondy, spolu se všemi devíti měřícími přístroji určenými ke zkoumání planety. Na závěr jsou popsány a okomentovány její dosavadní výsledky.

Order, Progress, and Ideal Government in Claudian's Epic De Raptu Proserpinae
Pastyříková, Iveta ; Bažil, Martin (advisor) ; Fořt, Bohumil (referee)
IVETA PASTYŘÍKOVÁ: ORDER, PROGRESS, AND IDEAL GOVERNMENT IN CLAUDIAN'S EPIC DE RAPTU PROSERPINAE ABSTRACT The aim of the diploma thesis is to show how late Ancient poet Claudius Claudianus deals with the problem of ideal government in the mythological epic De Raptu Proserpinae, by which strategies he exhorts his reader to evaluate Jupiter's rule in the world of the poem and to compare it with the situation in the real world. The chosen method is the theory of fictional worlds. Firstly, the thesis outlines the relation between the fictional world of the epic and the real world, then, the attention is paid to the essential question of this fictional world, ideal government. The thesis presents the prefaces of the epic as entrances into the fictional world foreshadowing topics elaborated in the world of the poem, where the ruler Jupiter has a difficult task ahead of him: to harmonize progress with protection against chaos. The last chapter summarizes the author's strategies and compares the epic with Claudian's other poems.

Dynamical processes in Jupiter's and Saturn's ring systems
Řehák, Matyáš ; Brož, Miroslav (advisor) ; Hanuš, Josef (referee)
The main subject of this thesis is a review of dynamical processes acting in Jupiter's and Saturn's rings. The thesis is divided into three chapters. Observed orbital and physical characteristics of the rings are described in the first one. In Chapter 2, we discuss physical processes forming the rings. Tidal disruptions, mutual collisions of ring particles, meteoroid bombardment and ballistic transport are among them. Various electromagnetic effects are analyzed too - e.g. the Poynting-Robertson effect, the Lorentz resonaces, plasma drag and radiation pressure. Yet another types of phenomena are resonant gravitational influence of satellites, shepherding moons and also collective dynamics of ring particles which results in formation of spiral waves. Finally, there is a review of theories concerning the origin of Saturn's rings in Chapter 3. We can distinguish three types of models - a disruption of a moon, a disruption of an external body and a formation from protolunar matter. At present, a tidal disruption of large differentiated moon seems to be the most probable theory.
