    • Downlink beamforming under individual SINR and per antenna power constraints 

      Yazarel, Y. K.; Aktaş, Defne (IEEE, 2007-08)
      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. ...
    • High optical efficiency of ZnO nanoparticles 

      Tek, Sümeyra; Demir, Hilmi Volkan; Yucel, D.; Celiker G. (IEEE, 2007)
      We develop optically efficient photocatalytic ZnO nanoparticles that we chemically embed and well disperse into host PVAc thin films and experimentally demonstrate the highest optical efficiency of ∼70% in ZnO nanoparticle ...
