Modulation of high-frequency QPOs
Bursa, Michal
2007 - English
We study strong-gravity effects on modulation of radiation emerging from accreting compact objects as a possible mechanism for flux modulation in QPOs. Zkoumáme vlivy silné gravitace na modulaci záření z akrečních disků jako možný zdroj mechanismus modulace kvaziperiodických oscilací.

Virtuální trojrozměrný prostor
Klvaňa, Miroslav
2005 - Czech
Práce se věnuje možnosti přímého vizuálního pozorování dvou barevných stereosko-pických obrazů, vedoucí k vyvolání prostorového vjemu, bez použití dalších technických pomůcek. Tento způsob vzniku trojdimenzionálního (3D) efektu je znám již z minulosti, informace o něm jsou však řídké a většinou povrchní. We investigate the possibility of a direct visual observation of two color stereoscopic images in order to perceive these images spatially without the use of further technical aids. Such a method of the 3D effect evoking is known since a long time ago, but there are not many information concerning it, and they are mostly very inaccurate.

Kinetic model of quasiperiodic oscillations of gaseous rings
Hadrava, Petr
2005 - English
In context of 3:2 resonant quasiperiodic oscillations, a method of "1+1/2 -dimensional" non-ideal gas dynamics is used to model axisymmetric oscillations of an orbiting ring. It is shown that the characteristic frequencies of the oscillations are influenced by the degree of freedom in the inner shear of the ring and by the rate of relaxation. Metoda "1+1/2 -dimensionalní" dynamiky neideálního plynu je užita k modelování orbitujícího disku v souvislosti s kvasiperiodickými oscilacemi v rezonanci 3:2. Je ukázáno, že charakteristické frekvence oscilací jsou ovlivněny vnitřním stupněm volnosti odpovídajícím smyku v prstenci a také mírou relaxace.
