      Continuous decaying of telco big data with data postdiction 

      Costa, Constantinos; Konstantinidis, Andreas; Charalampous, Andreas; Zeinalipour-Yazti, Demetrios; Mokbel, Mohamed F. (2019)
      In this paper, we present two novel decaying operators for Telco Big Data (TBD), coined TBD-DP and CTBD-DP that are founded on the notion of Data Postdiction. Unlike data prediction, which aims to make a statement about ...

      Decaying Telco Big Data with Data Postdiction 

      Costa, Constantinos; Charalampous, Andreas; Konstantinidis, Andreas; Zeinalipour-Yazti, Demetrios; Mokbel, Mohamed F. (2018)
      In this paper, we present a novel decaying operator for Telco Big Data (TBD), coined TBD-DP (Data Postdiction). Unlike data prediction, which aims to make a statement about the future value of some tuple, our formulated ...

      Epitaxially Oriented Sn:In2O3 Nanowires Grown by the Vapor–Liquid–Solid Mechanism on m-, r-, a-Al2O3 as Scaffolds for Nanostructured Solar Cells 

      Charalampous, Andreas; Zervos, Matthew; Kioseoglou, Joseph; Tsagaraki, Katerina; Androulidaki, Maria; Konstantinidis, George; Tanasă, Eugenia; Vasile, Eugeniu (2019)
      We have grown highly directional, epitaxial Sn:In2O3 nanowires via the vapor–liquid–solid mechanism on m-, r- and a-Al2O3 between 800 and 900 °C at 1 mbar. The Sn:In2O3 nanowires have the cubic bixbyite crystal structure ...

      Implementation, validation, and experimental evaluation of a self-stabilizing Byzantine-tolerant multivalued consensus algorithm 

      Charalampous, Andreas (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2022-07)
      Distributed computing has been in the foreground for decades, with distributed systems having numerous applications. Due to their architecture, one fundamental problem that these systems often need to solve is the consensus ...

      TBD-DP: Telco Big Data Visual Analytics with Data Postdiction 

      Costa, Constantinos; Charalampous, Andreas; Konstantinidis, Andreas; Zeinalipour-Yazti, Demetrios; Mokbel, Mohamed F. (2018)
      In this demonstration paper, we present the TBD-DP operator, which relies on existing Machine Learning (ML) algorithms to abstract Telco Big Data (TBD) into compact models that can be stored and queried when necessary. Our ...
