      Breaking the walls: Scene partitioning and portal creation 

      Lerner, A.; Chrysanthou, Yiorgos L.; Cohen-Or, D. (IEEE Computer Society, 2003)
      In this paper, we revisit the cells-and-portals visibility methods, originally developed for the special case of architectural interiors. We define an effectiveness measure for a cells-and-portals partitioning, and introduce ...

      Effect of posture change on the geometric features of the healthy carotid bifurcation 

      Aristokleous, Nicolas; Seimenis, Ioannis; Papaharilaou, Yannis; Georgiou, Georgios C.; Brott, B. C.; Eracleous, Eleni A.; Anayiotos, Andreas S. (2011)
      Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, ...

      Effects of the consistency of the fringing magnetic field on direct numerical simulations of liquid-metal flow 

      Albets-Chico, X.; Votyakov, E. V.; Radhakrishnan, H.; Kassinos, Stavros C. (2011)
      We investigate the effects of the consistency of strong fringing decreasing magnetic fields on numerical simulations of classical experimental data. Studies about fringing magnetic fields have attracted the attention of ...

      Femtosecond dynamics in single wall carbon nanotube/poly(3-hexylthiophene) composites 

      Lioudakis, Emmanouil E.; Othonos, Andreas S.; Alexandrou, Ioannis (2008)
      Femtosecond transient absorption measurements on single wall carbon nanotube/poly(3-hexylthiophene) composites are used to investigate the relaxation dynamics of this blended material. The influence of the addition of ...
