    • GRB Duration Distribution Considering the Position of the Fermi 

      Autor: Szécsi , D.; Bagoly , Z.; Horváth , I.; Balázs , L. G.; Veres , P.; Mészáros , A.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lightcurves of the GBM detectors are stressed ...

    • On the Relation Between GRB Classes and Xray Flashes 

      Autor: Bagoly , Z.; Veres , P.; Horváth , I.; Mészáros , A.; Balázs , L. G.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      Gamma-ray bursts are usually classified into either short-duration or long-duration bursts. Going beyond the short-long classification scheme, it has been shown on statistical grounds that a third, intermediate population ...

    • Plasma Flow and Temperature in a Gliding Reactor with Different Electrode Configurations 

      Autor: Sláma , J.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper deals with the plasma flow shape depending on the electrode form of a gliding discharge plasma-chemical reactor, and with the temperature distribution along the direction of the plasma flow in one specific ...

    • Prediction of Lower Extremity Movement by Cyclograms 

      Autor: Kutilek , P.; Viteckova , S.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      Human gait is nowadays undergoing extensive analysis. Predictions of leg movements can be used for orthosis and prosthesis programming, and also for rehabilitation. Our work focuses on predicting human gait with the use ...

    • Production of Biodiesel from Vegetable Oil Using Microware Irradiation 

      Autor: Kapilan , N.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The petroleum oil supply crisis, the increase in demand and the price eruption have led to a search for an alternative fuel of bio-origin in India. Among the alternative fuels, biodiesel is considered as a sustainable ...

    • S5 1803+78 Revisited 

      Autor: Nesci , R.; Maselli , A.; Montagni , F.; Sclavi , S.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      We report on our optical monitoring of the BL Lac object S5 1803+78 from 1996 to 2011. The source showed no clear periodicity, but a time scale of about 1 300 days between major flares is possibly present. No systematic ...

    • Structural Variability of 3C 111 on Parsec Scales 

      Autor: Grossberger , C.; Kadler , M.; Wilms , J.; Müller , C.; Beuchert , T.; Ros , E.; Ojha , R.; Aller , M.; Aller , H.; Angelakis , E.; Fuhrmann , L.; Nestoras , I.; Schmidt , R.; Zensus , J. A.; Krichbaum , T. P.; Ungerechts , H.; Sievers , A.; Riquelme , D.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      We discuss the parsec-scale structural variability of the extragalactic jet 3C111 related to a major radio flux density outburst in 2007. The data analyzed were taken within the scope of the MOJAVE, UMRAO, and F-GAMMA ...

    • 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, ...

    • 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 ...
