• 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. ...
    • Context-based storage management for wearable and portable devices 

      Karypidis, A.; Lalis, S. (2005)
      In our information-rich world, managing the data we collect is becoming a significant bottleneck for users. This issue has triggered considerable research in so-called semantic file systems, relying on the attachment of ...
    • A k-anonymity model for spatio-temporal data 

      Zacharouli, P.; Gkoulalas-Divanis, A.; Verykios, V. S. (2007)
      The unprecedented growth In Location-Based Services (LBS) take-up along with the continuously increasing storage capabilities of modern systems, and have facilitated the collection of information related to users activities ...
    • Memory management for receive-side enhancement of continuous media QoS 

      Spirou, S. (2005)
      Layering and conventional packet buffering in user-level continuous media receivers can increase end-to-end delay and packet loss. These QoS metrics and delay jitter can also deteriorate when general-purpose memory allocators ...
    • Merging R-trees 

      Vasaitis, V.; Nanopoulos, A.; Bozanis, P. (2004)
      R-trees, since their introduction in 1984, have been proven to be one of the most well-behaved practical data structures for accommodating dynamic massive sets of geometric objects and conducting a diverse set of queries ...
    • OmniStore: A system for ubiquitous personal storage management 

      Karypidis, A.; Lalis, S. (2006)
      As personal area networking becomes a reality, the collective management of storage in portable devices such as mobile phones, cameras and music players will grow in importance. The increasing wireless communication ...
    • Predictive join processing between regions and moving objects 

      Corral, A.; Torres, M.; Vassilakopoulos, M.; Manolopoulos, Y. (2008)
      The family of R-trees is suitable for indexing various kinds of multidimensional objects. TPR*-trees are R-tree based structures that have been proposed for indexing a moving object database, e.g. a data-base of moving ...
