      4G converged environment: Modeling network selection as a game 

      Antoniou, Josephina; Pitsillides, Andreas (2007)
      Network Selection mechanism in 4G mobile networks is a newly introduced mechanism that handles the selection of the best network to satisfy a service request. Network Selection needs to take part prior to admission of the ...

      Accounting standards convergence dynamics: International evidence from club convergence and clustering 

      Apergis, Nicholas; Christou, Christina; Hassapis, Christis (2014)
      Purpose - This paper aims to explore convergence of accounting standards across worldwide adopted measures to investigate whether countries that have not completely adopted International Accounting Standards across the ...

      Comparison of two methods for the computation of singular solutions in elliptic problems 

      Georgiou, Georgios C.; Boudouvis, Andreas G.; Poullikkas, A. (1997)
      We compare two numerical methods for the solution of elliptic problems with boundary singularities. The first is the integrated singular basis function method (ISBFM), a finite-element method in which the solution is ...

      Context-aware self-optimization in multiparty converged mobile environments 

      Antoniou, Josephina; Christophorou, C.; Neto, A.; Sargento, S.; Cabral Pinto, F.; Carapeto, N. F.; Mota, T.; Simoes, J.; Pitsillides, Andreas (2010)
      The increase of networking complexity requires the design of new performance optimization schemes for delivering different types of sessions to users under different conditions. In this scope, special attention is given ...

      Converged solutions of the Newtonian extrudate-swell problem 

      Georgiou, Georgios C.; Boudouvis, Andreas G. (1999)
      Both the axisymmetric and the planar Newtonian extrudate-swell problems are solved using the standard and the singular finite element methods. In the latter method, special elements that incorporate the radial form of the ...

      Deterministic assembly and anthropogenic extinctions drive convergence of island bird communities 

      Triantis, Kostas A.; Rigal, Francois; Whittaker, Robert J.; Hume, Julian P.; Sheard, Catherine; Poursanidis, Dimitrios; Rolland, Jonathan; Sfenthourakis, Spyros; Matthews, Thomas J.; Thebaud, Christophe; Tobias, Joseph A. (Wiley, 2022-06-10)
      Aim Whether entire communities of organisms converge towards predictable structural properties in similar environmental conditions remains controversial. We tested for community convergence in birds by comparing the ...

      Distributed Balancing of Commodity Networks Under Flow Interval Constraints 

      Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (2018)
      We consider networks the nodes of which are interconnected via directed edges, each able to admit a flow (or weight) within a certain interval, with nonnegative end points that correspond to lower and upper flow limits. ...

      Special boundary approximation methods for laplace equation problems with boundary singularities- Applications to the motz problem 

      Li, Z. C.; Chan, Y. L.; Georgiou, Georgios C.; Xenophontos, Christos A. (2006)
      We investigate the convergence of special boundary approximation methods (BAMs) used for the solution of Laplace problems with a boundary singularity. In these methods, the solution is approximated in terms of the leading ...

      Trends in international prices 

      Andrade, Philippe; Zachariadis, Marios (2010)
      We exploit the panel dimension of a price levels dataset for more than one hundred product items across 140 cities in 90 countries for the period from 1990 to 2009 in order to improve our understanding of international ...
