  • Mastorocostas, Paris; Varsamis, Dimitris; Hilas, Constantinos; Mastorocostas, Constantinos (2008-10)
    This paper presents a recurrent fuzzy-neural filter for adaptive noise cancelation. The cancelation task is transformed to a system-identification problem, which is tackled by use of the dynamic neuron-based fuzzy neural ...
  • Hilas, Constantinos S.; Kazarlis, Spyridon A.; Rekanos, Ioannis T.; Mastorocostas, Paris A. (2014-03)
    Telecommunications fraud has drawn the researchers’ attention due to the huge economic burden on companies and to the interesting aspect of users’ behavior modeling. In the present paper, an application of genetic ...

    t. Environmental monitoring and management are multidisciplinary tasks which require a continuous and close cooperation among involved stakeholders from various public entities, based in different locations. This fact ...
  • Perakis, Konstantinos; Moysiadis, Athanasios (2011-09)
    Sources of heterogeneous geospatial data such as the elevation, the slope, the aspect, the water network and the current settlements related to the known Neolithic archaeological sites of Magnesia, are used in an attempt ...
  • Evangelidis, Konstantinos; Ntouros, Konstantinos; Makridis, Stathis; Papatheodorou, Constantine (2014-02)
    Data semantics play an extremely significant role in spatial data infrastructures by providing semantic specifications to geospatial data and enabling in this way data sharing and interoperability. By applying, on the fly, ...
  • Papatheodorou, C.; Klimis, N.; Moutsokapas, Pr.; Koutrakis, S.; Margaris, B. (2007)
    The present work explores the ability of a GIS platform based tool to estimate potential losses of geotechnical earthquake hazard. Phenomena, such as liquefaction, dynamic settlements, lateral spreading, landslides and ...
  • Evangelidis, K.; Basbas, S.; Papaioannou, P. (2006)
    Humanity has faced an enormous technological evolution over the last 15 years in the area of Networks and Communications, in parallel with the continuous progress occurring in the computer hardware and software ...
  • Konstantinidis, A.; Evangelidis, K.; Stefanidou, E. (2005)
    Among the environmental problems emerged in the majority of modern cities, noise pollution along with air pollution is considered to be the most important ones. Traffic noise is a priority issue in the EU. According to a ...
  • Athanasenas, Athanasios; Katrakilidis, Constantinos; Trachanas, Emmanouil (2014-05)
    This paper attempts to re-evaluate the long-run macroeconomic relationship between government revenues and expenditures of the Greek economy over the period 1999–2010. The empirical analysis applies the newly developed ...
  • Kleidis, Kostas; Kuiroukidis, Apostolos; Papadopoulos, Demetrios B.; Vlahos, Loukas (2008)
    Gravitational instabilities in a magnetized Friedman–Robertson–Walker (FRW) universe, in which the magnetic field was assumed to be too weak to destroy the isotropy of the model, are known and have been studied in the past. ...
  • Kleidis, Kostas; Kuiroukidis, Apostolos; Papadopoulos, Demetrios B.; Verdaguer, Enric (2011-09-15)
    In a previous paper [K. Kleidis, D. B. Papadopoulos, E. Verdaguer, and L. Vlahos, Phys. Rev. D 78, 024027 (2008).] we considered the possibility that (within the early-radiation epoch) there has been (also) a short period ...
  • Chouliaras, Vasilios; Bogas, Christos G. (2011)
    During the 1990s the Greek economy has flourished, with the help of the banking system, which, at the same period, has undergone considerable deregulation. The stock market “explosion” at the end of the decade has provided ...
  • Folinas, Dimitrios; Aidonis, Dimitrios; Malindretos, Giorgos; Voulgarakis, Nikolaos; Triantafillou, Dimitrios (2014)
    In this paper, a systematic approach for measuring the environmental performance of a supply chain in agrifood sector based on the value stream mapping (VSM) technique is presented and analysed. The proposed approach aims ...
  • Κατσούλης, Γ.; Μοσχόπουλος, Α.; Ευαγγελίδης, Κ. (2010)
    Το παρόν άρθρο καλείται να επιβεβαιώσει την περιγραφή του πτυχιούχου του τμήματος Γεωπληροφορικής και Τοπογραφίας του Τεχνολογικού Εκπαιδευτικού Ιδρύματος Σερρών σύμφωνα με την οποία, ο απόφοιτος, μπορεί να υποστηρίξει ...
  • Kalomiros, J. A.; Lygouras, J. (2008-09)
    The design of a hardware co-processor for stereo depth detection, based on a parallel implementation of the sum of absolute differences algorithm, is presented. Model-based designs are followed, and a parameterisable open ...
  • Kalomiros, John; Vourvoulakis, John; Lygouras, John (2014)
    A new architecture for the real-time detection of scale-invariant features in image sequences is presented. The system is based on a low-cost smart-camera custom board, developed to target robotic vision applications. ...
  • Kalomiros, J. A.; Lygouras, J. (2008)
    This paper presents basic design principles for hardware implementation of a two-pass stereo-matching algorithm based on dynamic programming. For the first-pass a state-machine is proposed for the recursive calculation of ...
  • Kydros, Dimitrios; Notopoulos, Panagiotis; Exarchos, Georgios (2015-03)
    In this paper we provide some insights in Homer's Iliad from the perspective of social network analysis. We use the original text and other public available data to create a social network (i.e. a graph) that comprises of ...
