      A proposed extension of the CODAM model for human attention 

      Neokleous, Kleanthis C.; Avraamides, Marios N.; Ioannides, A. A.; Neocleous, Costas K.; Schizas, Christos N. (2009)
      A new computational model of visual attention is proposed on a theoretical basis, based on the CODAM model (Taylor, 2002, [25], 2006). Also a more general mechanism is proposed for an attention model of two or more senses ...

      Workload-aware query routing trees in wireless sensor networks 

      Andreou, Panayiotis G.; Zeinalipour-Yazdi, Constantinos D.; Chrysanthis, Panos K.; Samaras, George S. (2008)
      Continuous queries in wireless sensor networks are established on the premise of a routing tree that provides each sensor with a path over which answers can be transmitted to the query processor. We found that these ...
