    • The Algorithmic Aspects of Network Slicing 

      Vassilaras S., Gkatzikis L., Liakopoulos N., Stiakogiannakis I.N., Qi M., Shi L., Liu L., Debbah M., Paschos G.S. (2017)
      Network slicing is a technique for flexible resource provisioning in future wireless networks. With the powerful SDN and NFV technologies available, network slices can be quickly deployed and centrally managed, leading to ...

    • Computer-based methods in environmental data organization and management 

      Adam, G. K.; Tzortzios, S.; Dalezios, N. (2000)
      The protection of the environment is one of the main problems that mankind faces today. Recent advances in computer technology have assisted environmental studies towards this direction, in various scientific approaches. ...

    • Fisheye lens distortion correction on multicore and hardware accelerator platforms 

      Daloukas, K.; Antonopoulos, C. D.; Bellas, N.; Chai, S. M. (2010)
      Wide-angle (fisheye) lenses are often used in virtual reality and computer vision applications to widen the field of view of conventional cameras. Those lenses, however, distort images. For most real-world applications the ...

    • A Framework for developing Teamwork Enabled Services in Smart City Domains 

      Tsoutsa P., Iatrellis O., Ragos O., Fitsilis P. (2021)
      Services that collaborate alongside other services or systems for performing tasks, need to be aware of either predetermined or other abrupt and unexpected behaviors in other to adapt theirs. The service behaviors we ...

    • Gazing at the skyline for star scientists 

      Sidiropoulos A., Gogoglou A., Katsaros D., Manolopoulos Y. (2016)
      Admittedly, despite the plethora of scientometric indices proposed to rank scientists, none of them can fully capture the performance and impact of a scientist, since each index quantifies only one or a few aspects of ...

    • A Generalized Tonic-Clonic Seizure Detection Method in a Bathtub using a Natural Language Verification Step 

      Petroulaki O., Bicaku A., Kakarountas A. (2020)
      A Generalized Tonic-Clonic Seizure Detection Method in a Bathtub is proposed in this work, targeting mainly epileptic seizures. The main novelty of the presented methodology is found in the use of natural language ...

    • Information-Centric Connectivity 

      Katsaros K.V., Sourlas V., Psaras I., Rene S., Pavlou G. (2016)
      Mobile devices are often presented with multiple connectivity options, usually making a selection either randomly or based on the wireless medium's conditions, as is the case for current offloading schemes. In this article ...

    • The Insider Threat: Reasons, Effects and Mitigation Techniques 

      Tsiostas D., Kittes G., Chouliaras N., Kantzavelou I., Maglaras L., Douligeris C., Vlachos V. (2020)
      The insider threat is increasingly becoming extremely important for companies, organizations and even governments. A malicious, or even a careless, insider can cause severe damage to the resources and the reputation of an ...

    • Introducing Non-Computer Science Undergraduates to Web Development: Results of an Investigative Study on Student Teachers 

      Papastergiou, M. (2003)
      A series of workshops aming at introducing non-computer science undergraduates to web development were discussed. Forty-six second year student teachers participated in a series of eight two-hour workshops, organized within ...

    • Multicast-aware caching for small cell networks 

      Poularakis K., Iosifidis G., Sourlas V., Tassiulas L. (2016)
      The deployment of small cells is expected to gain huge momentum in the near future, as a solution for managing the skyrocketing mobile data demand growth. Local caching of popular files at the small cell base stations has ...

    • Sink Group Betweenness Centrality 

      Fragkou E., Katsaros D., Manolopoulos Y. (2021)
      This article introduces the concept of Sink Group Node Betweenness centrality to identify those nodes in a network that can "monitor"the geodesic paths leading towards a set of subsets of nodes; it generalizes both the ...

    • A spatial index for hybrid storage 

      Fevgas A., Bozanis P. (2019)
      The introduction of flash SSDs has accelerated the performance of DBMSes. However, the intrinsic characteristics of flash motivated many researchers to investigate new efficient data structures. The emergence of 3DXPoint, ...

    • Transmission of correlated Gaussian sources with opportunistic interference 

      Alay O., Argyriou A. (2016)
      Interfering transmissions of independent sources is shown to provide benefits at a cost of complex receiver design. In this paper, we study the optimum transmission of correlated Gaussian sources by allowing opportunistic ...
