    • 3D forest fire propagation simulation 

      Köse K.; Grammalidis, N.; Yilmaz, E.; Çetin, E. (2008)
      The increase in the number of forest fires in the last few years dispatch governments to take precautions. Besides prevention, early intervention is also very important in fire fighting. If the firefighters know where the ...
    • Accurate positioning in ultra-wideband systems 

      Soganci, H.; Gezici, S. (Institute of Electrical and Electronics Engineers, 2011)
      Accurate positioning systems can be realized via ultra-wideband signals due to their high time resolution. In this article, position estimation is studied for UWB systems. After a brief introduction to UWB signals and their ...
    • Autonomous multiple teams establishment for mobile sensor networks by SVMs within a potential field 

      Nazlibilek, S. (2012)
      In this work, a new method and algorithm for autonomous teams establishment with mobile sensor network units by SVMs based on task allocations within a potential field is proposed. The sensor network deployed into the ...
    • Coincidence of Myerson allocation rule with Shapley value 

      Kapan, Tümer (Bilkent University, 2003)
      This thesis studies the coincidence of the Myerson allocation rule in the context of networks with the Shapley value in the context of transferable utility games. We start with a value function defined on networks and ...
    • Diffusion approximation in overloaded switching queueing models 

      Anisimov, V. V. (Springer, 2002)
      The asymptotic behavior of a queueing process in overloaded state-dependent queueing models (systems and networks) of a switching structure is investigated. A new approach to study fluid and diffusion approximation type ...
    • Distributed k-Core view materialization and maintenance for large dynamic graphs 

      Aksu, H.; Canim, M.; Chang, Yuan-Chi; Korpeoglu, I.; Ulusoy, O. (Institute of Electrical and Electronics Engineers, 2014-10)
      In graph theory, k-core is a key metric used to identify subgraphs of high cohesion, also known as the ‘dense’ regions of a graph. As the real world graphs such as social network graphs grow in size, the contents get ...
    • Document replication strategies for geographically distributed web search engines 

      Kayaaslan, E.; Cambazoglu, B. B.; Aykanat, C. (Elsevier Ltd., 2013)
      Large-scale web search engines are composed of multiple data centers that are geographically distant to each other. Typically, a user query is processed in a data center that is geographically close to the origin of the ...
    • Essays in collective decision making 

      Derya, Ayşe Mutlu (Bilkent University, 2014-10)
      Four different problems in collective decision making are studied, all of which are either formulated directly in a game-theoretical context or are concerned with neighboring research areas. The rst two problems fall ...
    • Essays on bargaining theory 

      Özcan Tok, Elif (Bilkent University, 2018-06)
      Bargaining refers to a situation where two or more agents try to decide over how to divide a surplus generated by the economic transactions among these agents. There are two major approaches to bargaining problems: ...
    • Network dependent altruism and economic growth 

      Çetin, Sefane (Bilkent University, 2016-07)
      This thesis studies reference dependent agents in a static network where the reference point is the average behaviour in one's neighbourhood. It shows that the economy grows at a constant rate on the balanced growth path ...
    • PSAR: Power-source-aware routing in ZigBee networks 

      Tekkalmaz, M.; Korpeoglu I. (2012)
      ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of ...
    • A scheme for handling connectionless services in connection-oriented networks 

      Abdelati, M.; Arikan, E. (The Institute of Electronics, Information and Communication Engineers, 1997-10-25)
      In this work we propose a pricing scheme which serves as an instrument for managing connectionless services in connection-oriented communication networks. The scheme is able to allocate network bandwidth in a Pareto-optimal ...
