      The Effect of Head Rotation on the Geometry and Hemodynamics of Healthy Vertebral Arteries 

      Aristokleous, Nicolas; Seimenis, Ioannis; Georgiou, Georgios C.; Nicolaïdes, Andrew N.; Anayiotos, Andreas S. (2015)
      The geometric and hemodynamic characteristics of the left and right vertebral arteries (LVA, RVA) of six healthy volunteers were investigated for the supine (S) and the prone position (P) a common sleeping posture with ...

      Folk dance evaluation using laban movement analysis 

      Aristidou, Andreas; Stavrakis, E.; Charalambous, Panayiotis; Chrysanthou, Yiorgos L.; Himona, S. L. (2015)
      Motion capture (mocap) technology is an efficient method for digitizing art performances, and is becoming increasingly popular in the preservation and dissemination of dance performances. Although technically the captured ...

      Image-based crowd rendering 

      Tecchia, F.; Loscos, C.; Chrysanthou, Yiorgos L. (2002)
      Rendering crowded scenes with thousands of different animated virtual people in real time is challenging. An image-based rendering approach for displaying multiple avatars is proposed. The system allows real-time rendering ...

      Protein secondary structure prediction with bidirectional recurrent neural nets: Can weight updating for each residue enhance performance? 

      Agathocleous, Michalis; Christodoulou, Georgia; Promponas, Vasilis J.; Christodoulou, Chris C.; Vassiliades, Vassilis; Antoniou, Antonis (2010)
      Successful protein secondary structure prediction is an important step towards modelling protein 3D structure, with several practical applications. Even though in the last four decades several PSSP algorithms have been ...

      Real-time shadows for animated crowds in virtual cities 

      Loscos, C.; Tecchia, F.; Chrysanthou, Yiorgos L. (2001)
      In this paper, we address the problem of shadow computation for large environments including thousands of dynamic objects. The method we propose is based on the assumption that the environment is 2.5D, which is often the ...

      Reconstruction of everyday life in 19th century Nicosia 

      Charalambous, Panayiotis; Iliadou, H.; Apostolou, C.; Chrysanthou, Yiorgos L. (2012)
      This paper presents the first stages of a larger project concerning the study and realization of a 3D interactive environment of everyday life in 19th century Nicosia. The presented study involves the recreation of the ...

      Thermal characterization of cloud workloads on a power-efficient server-on-chip 

      Milojevic, D.; Idgunji, S.; Jevdjic, D.; Ozer, E.; Lotfi-Kamran, P.; Panteli, Andreas; Prodromou, Andreas; Nicopoulos, Chrysostomos A.; Hardy, D.; Falsari, B.; Sazeides, Yiannakis (2012)
      We propose a power-efficient many-core server-on-chip system with 3D-stacked Wide I/O DRAM targeting cloud workloads in datacenters. The integration of 3D-stacked Wide I/O DRAM on top of a logic die increases available ...

      Three dimensional flow around a circular cylinder confined in a plane channel 

      Kanaris, N.; Grigoriadis, D. G. E.; Kassinos, Stavros C. (2011)
      This paper presents two- and three-dimensional direct numerical simulations of the flow around a circular cylinder placed symmetrically in a plane channel. Results are presented in the Reynolds number range (based on the ...

      Toward energy-aware balancing of mobile graphics 

      Stavrakis, E.; Polychronis, M.; Pelekanos, Nectarios; Artusi, A.; Hadjichristodoulou, P.; Chrysanthou, Yiorgos L. (SPIE, 2015)
      In the area of computer graphics the design of hardware and software has primarily been driven by the need to achieve maximum performance. Energy efficiency was usually neglected, assuming that a stable always-on power ...

      View volume culling using a probabilistic caching scheme 

      Slater, Mel; Chrysanthou, Yiorgos L. (ACM, 1997)
      This paper a new algorithm for view volume culling. During an interactive walkthrough of a 3D scene, at any moment a large proportion of objects will be outside of the view volume. Frame-to-frame coherence implies that the ...

      Viewspace partitioning of densely occluded scenes 

      Chrysanthou, Yiorgos L.; Cohen-Or, Daniel; Zadicario, Eyal (ACM, 1998)
      Computing the visibility of out-door scenes is often much harder than of in-door scenes. The difficulty is that although the majority of objects are hidden, some parts might be visible at a distance in an arbitrary location, ...

      Visualizing crowds in real-time 

      Tecchia, F.; Loscos, C.; Chrysanthou, Yiorgos L. (2002)
      Real-time crowd visualization has recently attracted quite an interest from the graphics community and, as interactive applications become even more complex, there is a natural demand for new and unexplored application ...
