    • Data replication versus timing constraints in distributed database systems 

      Ulusoy, Özgür (ACM, 1994-03)
      In a database system supporting a real-time application, each transaction is associated with a timing constraint, typically in the form of a deadline. Replicated database systems possess desirable features for real-time ...
    • Data-parallel web crawling models 

      Cambazoglu, B. B.; Turk, A.; Aykanat, C. (Springer, 2004)
      The need to quickly locate, gather, and store the vast amount of material in the Web necessitates parallel computing. In this paper, we propose two models, based on multi-constraint graph-partitioning, for efficient ...
    • A database model for querying visual surveillance videos by integrating semantic and low-level features 

      Şaykol, Ediz; Güdükbay, Uğur; Ulusoy, Özgür (Springer, Berlin, Heidelberg, 2005)
      Automated visual surveillance has emerged as a trendy application domain in recent years. Many approaches have been developed on video processing and understanding. Content-based access to surveillance video has become a ...

      The research activities of the Database Research Group of Bilkent University are discussed. The research is mainly focused on the topics of multimedia databases, Web databases, and mobile computing. The Ottoman Archive ...
    • DBPal: A learned NL-interface for databases 

      Basık, Fuat; Hättasch, B.; Ilkhechi, A.; Usta, A.; Ramaswamy, S.; Utama, P.; Weir, N.; Binnig, C.; Cetintemel, U. (ACM, 2018)
      In this demo, we present DBPal, a novel data exploration tool with a natural language interface. DBPal leverages recent advances in deep models to make query understanding more robust in the following ways: First, DBPal ...
    • Dealing with fuzziness in active mobile database systems 

      Saygın, Y.; Ulusoy, Ö.; Yazıcı, A. (Elsevier, 1999)
      Current needs of industry required the development of advanced database models like active mobile database systems. An active mobile database system can be designed by incorporation of triggering rules into a mobile computing ...
    • Decision support for adopting SPLE with transit-PL 

      Kalender, Mert Emin; Tüzün, E.; Tekinerdoğan, Bedir (ACM, 2013)
      It is generally acknowledged that the decision to adopt a software product line engineering (SPLE) approach needs to be performed carefully due to the di• erent risks involved in taking such an important decision. To ...
    • A decision theoretic approach to motion saliency in computer animations 

      Arpa, Sami; Bülbül, Abdullah; Çapın, Tolga (Springer, Berlin, Heidelberg, 2011)
      We describe a model to calculate saliency of objects due to their motions. In a decision-theoretic fashion, perceptually significant objects inside a scene are detected. The work is based on psychological studies and ...
    • Decomposing linear programs for parallel solution 

      Pınar, Ali; Çatalyürek Ümit V.; Aykanat, Cevdet; Pınar, Mustafa (Springer, 1995-08)
      Coarse grain parallelism inherent in the solution of Linear Programming (LP) problems with block angular constraint matrices has been exploited in recent research works. However, these approaches suffer from unscalability ...
    • Decompositional analysis of Kronecker structured Markov chains 

      Bao, Y.; Bozkur, I. N.; Dayar, T.; Sun, X.; Trivedi, K. S. (Kent State University, 2008)

    • A decoupled local memory allocator 

      Diouf, B.; Hantaş, C.; Cohen, A.; Özturk, Ö.; Palsberg, J. (Association for Computing Machinery, 2013)
      Compilers use software-controlled local memories to provide fast, predictable, and power-efficient access to critical data. We show that the local memory allocation for straight-line, or linearized programs is equivalent ...
