      A distributed visualization system for crowd simulations 

      Vigueras, G.; Orduña, J. M.; Lozano, M.; Chrysanthou, Yiorgos L. (2011)
      The visualization system of large-scale crowd simulations should scale up with both the number of visuals (views of the virtual world) and the number of agents displayed in each visual. Otherwise, we could have large scale ...

      Fast approximate visibility on the GPU using pre-computed 4D visibility fields 

      Gaitatzes, Athanasios; Andreadis, Anthousis; Papaioannou, Georgios J.; Chrysanthou, Yiorgos L. (2010)
      We present a novel GPU-based method for accelerating the visibility function computation of the lighting equation in dynamic scenes composed of rigid objects. The method pre-computes, for each object in the scene, the ...

      Feature mapping through maximization of the atomic interclass distances 

      Karatsiolis, Savvas; Schizas, Christos N. (2015)
      We discuss a way of implementing feature mapping for classification problems by expressing the given data through a set of functions comprising of a mixture of convex functions. In this way, a certain pattern’s potential ...

      Intensive care window: Real-time monitoring and analysis in the intensive care environment 

      Stylianides, N.; Dikaiakos, Marios D.; Gjermundrød, H.; Panayi, G.; Kyprianou, T. (2011)
      This paper introduces a novel, open-source middleware framework for communication with medical devices and an application using the middleware named intensive care window (ICW). The middleware enables communication with ...

      Model-based cluster analysis for Web users sessions 

      Pallis, George C.; Angelis, Lefteris; Vakali, Athena I. (2005)
      One of the main issues in Web usage mining is the discovery of patterns in the navigational behavior of Web users. Standard approaches, such as clustering of users' sessions and discovering association rules or frequent ...

      Optimal scanning, display, and segmentation of the International Labor Organization (ILO) x-ray images set for pneumoconiosis 

      Pattichis, Marios S.; Ramachandran, J.; Wilson, M.; Pattichis, Constantinos S.; Soliz, P. (2001)
      A method for scanning and displaying chest radiographs (x-rays) is presented. The new method treats scanning independent of display, allowing for maximum information content to be captured during the scanning process, and ...

      Our climate, our change - using digital learning objects to present the complex science of global climate change 

      Martin, Brian; Mahaffy, Peter (University of Cyprus, 2010)
      Global Climate Change (GCC) is arguably one of the most significant challenges ever faced by humankind. The complex science of GCC leaves the general public and teachers at both secondary school and tertiary levels perplexed.. ...

      Presampled visibility for ambient occlusion 

      Gaitatzes, Athanasios; Chrysanthou, Yiorgos L.; Papaioannou, Georgios J. (2008)
      We present a novel method to accelerate the computation of the visibility function of the lighting equation, in dynamic scenes composed of rigid, non-penetrating objects. The main idea of the technique is to pre-compute ...
