    • Scheduling Video Transcoding Jobs in the Cloud 

      Oikonomou P., Koziri M.G., Tziritas N., Dadaliaris A.N., Loukopoulos T., Stamoulis G.I., Khan S.U. (2018)
      Video transcoding is the process of producing from an original (already encoded) input video sequence, multiple output sequences, each at potentially different bitrate, resolution and/or format. Transcoding is essential ...

    • A significance-driven programming framework for energy-constrained approximate computing 

      Vassiliadis V., Chalios C., Parasyris K., Antonopoulos C.D., Lalis S., Bellas N., Vandierendonck H., Nikolopoulos D.S. (2015)
      Approximate execution is a viable technique for energy-constrained environments, provided that applications have the mechanisms to produce outputs of the highest possible quality within the given energy budget. We introduce ...

    • 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 ...
