    • Age related changes in ocular motor testing in healthy subjects 

      Seferlis, F.; Chimona, T. S.; Papadakis, C. E.; Bizakis, J.; Triaridis, S.; Skoulakis, C. (2015)
      The aim of the present study was the investigation of age influenced changes in ocular motility testing in healthy subjects. Two hundred and fifty subjects between 18 and 70 years old were enrolled in a prospective study. ...

    • Blind adaptive channel estimation in OFDM Systems 

      Doukopoulos, X. G.; Moustakides, G. V. (2006)
      We consider the problem of blind channel estimation in zero padding OFDM systems, and propose blind adaptive algorithms in order to identify the impulse response of the multipath channel. In particular, we develop RLS and ...

    • Navigated DENSE strain imaging for post-radiofrequency ablation lesion assessment in the swine left atria 

      Schmidt, E. J.; Fung, M. M.; Ciris, P. A.; Song, T.; Shankaranarayanan, A.; Holmvang, G.; Gupta, S. N.; Chaput, M.; Levine, R. A.; Ruskin, J.; Reddy, V. Y.; D'Avila, A.; Aletras, A. H.; Danik, S. B. (2014)
      Aims Prior work has demonstrated that magnetic resonance imaging (MRI) strain can separate necrotic/stunned myocardium from healthy myocardium in the left ventricle (LV). We surmised that high-resolution MRI strain, using ...

    • Optimal decentralized Kalman filter and Lainiotis filter 

      Assimakis, N.; Adam, M.; Koziri, M.; Voliotis, S.; Asimakis, K. (2013)
      A method to implement the optimal decentralized Kalman filter and the optimal decentralized Lainiotis filter is proposed; the method is based on the a priori determination of the optimal distribution of measurements into ...

    • Refinement of human silhouette segmentation in omni-directional indoor videos 

      Delibasis, K. K.; Plagianakos, V. P.; Maglogiannis, I. (2014)
      In this paper, we present a methodology for refining the segmentation of human silhouettes in indoor videos acquired by fisheye cameras. This methodology is based on a fisheye camera model that employs a spherical optical ...

    • A three year study of coronary heart disease risk factors in Greek adolescents 

      Bouziotas, C.; Koutedakis, Y. (2003)
      We examined the prevalence of 14 modifiable CHD risk factors in a sample of 210 provincial Greek children as they progressed from age 12 to 14. It was found that 46.2% of boys and 49.5%,of girls (p > 0.05) exhibited three ...
