    • Adaptive routing framework for network on chip architectures 

      Mustafa, N. U.; Ozturk, O.; Niar, S. (Association for Computing Machinery, 2016)
      In this paper we suggest and demonstrate the idea of applying multiple routing algorithms during the execution of a real application mapped on a Network-on-Chip (NoC). Traffic pattern of a real application may change during ...
    • Capture resilient ElGamal signature protocols 

      Acan, H.; Kaya, K.; Selçuk, A. A. (Springer Verlag, 2006)
      One of the fundamental problems of public key cryptography is protecting the private key. Private keys are too long to be remembered by the user, and storing them in the device which performs the private key operation is ...
    • 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 ...
    • Fault-tolerant irregular topology design method for network-on-chips 

      Tosun, S.; Ajabshir V.B.; Mercanoglu O.; Ozturk, O. (Institute of Electrical and Electronics Engineers Inc., 2014)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Fault-tolerant topology generation method for application-specific network-on-chips 

      Tosun, S.; Ajabshir, V. B.; Mercanoglu, O.; Ozturk, O. (Institute of Electrical and Electronics Engineers, 2015)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Heterogeneous network-on-chip design through evolutionary computing 

      Ozturk, O.; Demirbas, D. (Taylor & Francis, 2010)
      This article explores the use of biologically inspired evolutionary computational techniques for designing and optimising heterogeneous network-on-chip (NoC) architectures, where the nodes of the NoC-based chip multiprocessor ...
    • On the reliability exponent of the exponential timing channel 

      Arikan, E. (IEEE, 2002)
      We determine the reliability exponent E(R) of the Anantharam-Verdú exponential server timing channel with service rate μ for all rates R between a critical rate R c = (μ/4) log 2 and the channel capacity C = e -1μ. For ...
    • Online balancing two independent criteria 

      Tse, S.S.H. (2008)
      We study the online bicriteria load balancing problem in this paper. We choose a system of distributed homogeneous file servers located in a cluster as the scenario and propose two online approximate algorithms for balancing ...
    • Online bicriteria load balancing for distributed file servers 

      Tse, S. (IEEE, 2008)
      We study the online bicriteria load balancing problem in a system of M distributed homogeneous file servers located in a cluster. The load and storage space are assumed to be independent. We propose two online approximate ...
    • Online bicriteria load balancing using object reallocation 

      Tse, S. S. H. (Institute of Electrical and Electronics Engineers, 2009-03)
      We study the bicriteria load balancing problem on two independent parameters under the allowance of object reallocation. The scenario is a system of $M$ distributed file servers located in a cluster, and we propose three ...
    • Online solutions for scalable file server systems 

      Tse, S.S.H. (2006)
      We propose three online algorithms for scalable file server systems. A scalable file server is expected to provide rather stable services while the numbers of users, tasks, and data volumes keep increasing. One of the ...
    • Parallel dedicated machine scheduling with A single server: Full precedence case 

      Schultz, S.R.; Taner, M.R. (2004)
      The motivation for this study was the observation of a practical scenario that involves scheduling of two parallel machines attended by a single setup crew so as to minimize the makespan. This problem is known in scheduling ...
    • Real-time color holographic video display system 

      Yaraş, F.; Kang, H.; Onural, L. (IEEE, 2009)
      A real-time multi-GPU color holographic video display system computes holograms from 3D video of a rigid object. System has three main stages; client, server and optics. 3D coordinate and texture information are kept in ...
    • A simple and effective mechanism for stored video streaming with TCP transport and server-side adaptive frame discard 

      Gürses, E.; Akar, G. B.; Akar, N. (Elsevier, 2005)
      Transmission control protocol (TCP) with its well-established congestion control mechanism is the prevailing transport layer protocol for non-real time data in current Internet Protocol (IP) networks. It would be desirable ...
    • Solving the single server semi-Markov queue with matrix exponential kernel matrices for interarrivals and services 

      Akar, N.; Sohraby, K. (2006)
      Markov renewal processes with semi-Markov kernel matrices that have matrix-exponential representations form a superset of the well-known phase-type renewal process, Markovian arrival process, and the recently introduced ...
