    Özcan, Rıfat (Bilkent University, 2011)
    Large scale search engines have to cope with increasing volume of web content and increasing number of query requests each day. Caching of query results is one of the crucial methods that can increase the throughput of ...
  • Causality analysis in biological networks 

    Babur, Özgün (Bilkent University, 2010)
    Systems biology is a rapidly emerging field, shaped in the last two decades or so, which promises understanding and curing several complex diseases such as cancer. In order to get an insight about the system – specifically ...
  • Characteristics of Web-based textual communications 

    Küçükyılmaz, Tayfun (Bilkent University, 2012)
    In this thesis, we analyze different aspects of Web-based textual communications and argue that all such communications share some common properties. In order to provide practical evidence for the validity of this argument, ...
  • Communication models for crowd simulation 

    Küllü, Kurtuluş (Bilkent University, 2017-08)
    Modeling and animation of behaviorally plausible virtual crowds are important problems of crowd simulation research. We propose a communication model in order to equip virtual agents with the ability to autonomously ...
  • Computational situation theory with baby-sit 

    Tin, Erkan (Bilkent University, 1995)
    Language is an integral part of our everyday experience and encompasses situated activities such as talking, listening, reading, and writing. These activities are situated because they occur in situations and they are about ...
  • Counteracting free riding in pure peer-to-peer networks 

    Karakaya, K Murat (Bilkent University, 2008)
    The peer-to-peer (P2P) network paradigm has attracted a significant amount of interest as a popular and successful alternative to traditional client-server model for resource sharing and content distribution. However, ...
