      Fullsphere irradiance factorization for real-time all-frequency illumination for dynamic scenes 

      Michael, D.; Chrysanthou, Yiorgos L. (2010)
      Computation of illumination with soft-shadows from all-frequency environment maps, is a computationally expensive process. Use of pre-computation add the limitation that receiver's geometry must be known in advance, since ...

      In situ observation of rapid reactions in nanoscale Ni-Al multilayer foils using synchrotron radiation 

      Fadenberger, K.; Gunduz, Ibrahim Emre; Tsotsos, Chrysostomos; Kokonou, Maria; Gravani, S.; Brandstetter, Stefan; Bergamaschi, Anna; Schmitt, Bernd; Mayrhofer, Paul H.; Doumanidis, C. C.; Rebholz, Claus (2010)
      The observation of rapid reactions in nanoscale multilayers present challenges that require sophisticated analysis methods. We present high-resolution in situ x-ray diffraction analysis of reactions in nanoscale foils of ...

      Shadow volume BSP trees for computation of shadows in dynamic scenes 

      Chrysanthou, Yiorgos L.; Slater, Mel (ACM, 1995)
      This paper presents an algorithm for shadow calculation in dynamic polyhedral scenes illuminated by point light sources. It is based on a modification of Shadow Volume Binary Space Partition trees, to allow these be ...

      Thin liquid crystal film for corrosion sensing 

      Kossivas, F.; Kyprianou, Andreas (2008)
      The anchoring energy of Liquid Crystals (LCs) is influenced by several parameters. Many scientists have exploited LCs anchoring in order to develop several LC based optical sensors. This paper proposes and proves a new ...
