    • Structural performance of TS590 high-strength steel welded tubular joints under extreme bending loading 

      Varelis, G. E.; Karamanos, S. A.; Papatheocharis, T.; Perdikaris, P. C. (2012)
      The present work examines the behavior of welded tubular connections made of high-strength steel and subjected to extreme loading conditions focusing on their low-cycle fatigue performance and highlighting the benefits of ...

    • A study of flow in open channels with vegetation: Experiments and numerical models 

      Keramaris E., Kasiteropoulou D., Liakopoulos A., Michalolias N., Pechlivanidis G. (2017)
      In this study, the flow in open channels with vegetation was experimentally and numerically investigated. Particle image velocimetry (PIV) measurements and a computational fluid dynamics model are presented. In order to ...

    • Ultimate capacity of pipe bends under bending and pressure 

      Pappa, P.; Karamanos, S. A.; Tsouvalas, D.; Houliara, S. (2008)
      The structural capacity of pressurized pipe elbows under in-plane bending is examined. The investigation is conducted through advanced finite element analysis tools. The numerical results are successfully compared with ...

    • Video delivery over heterogeneous cellular networks: Optimizing cost and performance 

      Poularakis, K.; Iosifidis, G.; Argyriou, A.; Tassiulas, L. (2014)
      Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ...

    • Wireless-optical network convergence: Enabling the 5G architecture to support operational and end-user services 

      Tzanakaki A., Anastasopoulos M., Berberana I., Syrivelis D., Flegkas P., Korakis T., Mur D.C., Demirkol I., Gutierrez J., Grass E., Wei Q., Pateromichelakis E., Vucic N., Fehske A., Grieger M., Eiselt M., Bartelt J., Fettweis G., Lyberopoulos G., Theodoropoulou E., Simeonidou D. (2017)
      This article presents a converged 5G network infrastructure and an overarching architecture to jointly support operational network and end-user services, proposed by the EU 5G PPP project 5G-XHaul. The 5G-XHaul infrastructure ...

    • Wrinkling of lined steel pipes under bending 

      Vasilikis, D.; Karamanos, S. A. (2013)
      Lined pipes are used in energy pipeline applications (oil, gas, etc.); a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on wrinkling of lined pipes (sometimes also ...
