    • Cooperative transmission for multiuser MIMO systems 

      Yazarel, Y.K.; Aktaş, D. (2008)
      In this work, we investigate the problem of jointly determining the optimal transmission scheme at the base stations in a cooperative multiuser multiple antenna system. In this optimization problem, different than majority ...

    • Downlink beamforming under individual SINR and per antenna power constraints 

      Yazarel, Y.K.; Aktas, D. (2007)
      In this paper we consider the problem of finding the optimum beamforming vectors for the downlink of a multiuser system, where there are individual signal to interference plus noise ratio (SINR) targets for each user. ...

    • Effect on scaling of heat removal requirements in three-dimensional systems 

      Ozaktas, H., M.; Oksuzoglu H.; Pease, R.F.W.; Goodman J.W. (1992)
      A first-order discussion of convective heat removal from a hypothetical 3-dimensional computing system is presented. A textbook treatment indicates that our heat removal capability can be characterized by a quantity Q, the ...

    • Fundamentals of optical interconnections-a review 

      Özaktaş, Haldun M. (IEEE, Los Alamitos, CA, United States, 1997)
      We review some of the relatively fundamental work in the area of optically interconnected digital computing systems. We cover comparisons of optical interconnections with other interconnection media in terms of energy and ...

    • An information-theoretic analysis of Grover's algorithm 

      Arikan, E. (2003)
      A quantum algorithm for identifying a target element in an unstructured search universe of N items in approximately π/4√N queries to a quantum oracle was discovered. It was proved that this square-root speed-up was the ...

    • Parsing Turkish using the lexical functional grammar formalism 

      Güngördü, Z.; Oflazer, K. (Springer/Kluwer Academic Publishers, 1995)
      This paper describes our work on parsing Turkish using the lexical-functional grammar formalism [11]. This work represents the first effort for wide-coverage syntactic parsing of Turkish. Our implementation is based on ...

    • PocketDrive: A system for mobile control of desktop PC and its applications using PDAs 

      Yildirim, Y.; Korpeoglu I. (2007)
      Today, consumer electronic devices and PCs are inevitable parts of our daily life. Controlling those devices remotely is an important aspect of the technology. We have already universal remote control devices for controlling ...

    • Progressive refinement radiosity on ring-connected multicomputers 

      Çapın, T. K.; Aykanat, C.; Özgüç, B. (Publ by ACM, New York, NY, United States, 1993)
      The progressive refinement method is investigated for parallelization on ring-connected multicomputers. A synchronous scheme, based on static task assignment, is proposed, in order to achieve better coherence during the ...

    • Research issues in peer-to-peer data management 

      Ulusoy, Ö. (IEEE, 2007)
      Data management in Peer-to-Peer (P2P) systems is a complicated and challenging issue due to the scale of the network and highly transient population of peers. In this paper, we identify important research problems in P2P ...
