    • The Electrification of Tramways in Ostrava in 1900–1901 

      Autor: Závodná , Michaela
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper focuses on the electrification of tramways in Ostrava in 1900-1901. As the administrative, economic and cultural centre of an evolving industrial agglomeration, Ostrava had specific transportation requirements. ...

    • The Intriguing Nature of the Cataclysmic Variable SS Cygni 

      Autor: Giovannelli , F.; Sabau-Graziati , L.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The classification of SS Cyg as a dwarf nova (DN), a subclass of the non–magnetic (NM) cataclysmic variable (CV) has been considered by most of the community as well established because of a paper appeared in Nature (Bath ...

    • The Optical Transient Search in the Bamberg Southern Sky Survey: Preliminary Results 

      Autor: Hudec , R.; Kopel , F.; Krapp , P.; Heber , U.; Cayé , W.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      A large fraction of gamma-ray bursts temporarily emit optical light, i.e. optical afterglows and optical transients. So far, optical transients have only been detected after related gamma-ray satellite detection. However, ...

    • The Simulation of the Influence of Water Remnants on a Hot Rolled Plate after Cooling 

      Autor: Zahradník , Radek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In situations when a sheet metal plate of large dimensions is rolled, water remnants from cooling can be observed on the upper side of the plate. This paper focuses on deformations of a hot rolled sheet metal plate that ...

    • Transonic Flow of Wet Steam — Numerical Simulation 

      Autor: Halama , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper ...

    • Ultra Low Dispersion Spectroscopy with Gaia and Astronomical Slitless Surveys 

      Autor: Hudec , R.; Hudec , L.; Klíma , M.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The ultra-low dispersion spectroscopy to be applied in the ESA Gaia space observatory and the ground-based objective-prism plate surveys represent a similar type of astrophysical data. Although the dispersion in plate ...

    • Use of Grasses and Mixtures of Grasses for Energy Purposes 

      Autor: Andert , David; Frydrych , Jan; Gerndtová , Ilona
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      As levels of agricultural productivity increase, there is also an increase in land area not utilized for food production. This area can be used for growing energy crops, including grasses. When land is set aside for grassing, ...

    • Utilization of Image Intensifiers in Astronomy 

      Autor: Vítek , S.; Fliegel , K.; Páta , P.; Koten , P.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In this paper we present the properties of image intensifiers, used together with fast TV cameras for astronomical purposes within the MAIA project(Meteor Automatic Imager and Analyser, primarily focused on observing ...
