    • Aggregate profile clustering for streaming analytics 

      Abbasoğlu, M. A.; Gedk, B.; Ferhatosmanoğu H. (Oxford University Press, 2015)
      Many analytic applications require analyzing user interaction data. In particular, such data can be aggregated over a window to build user activity profiles. Clustering such aggregate profiles is useful for grouping together ...
    • Aggregate profile clustering for telco analytics 

      Abbasoğlu, M.A.; Gedik, B.; Ferhatosmanoğlu H. (2013)
      Many telco analytics require maintaining call profiles based on recent customer call patterns. Such call profiles are typically organized as aggregations computed at different time scales over the recent customer interactions. ...
    • Dynamic capacity management for voice over packet networks 

      Akar, Nail; Şahin, Cem (2003-06-07)
      In this paper, dynamic capacity management refers to the process of dynamically changing the capacity allocation (reservation) of a pseudo-wire established between two network end points. This process is based on certain ...
    • Dynamic risk spillovers between gold, oil prices and conventional, sustainability and Islamic equity aggregates and sectors with portfolio implications 

      Mensi, W.; Hammoudeh, S.; Al-Jarrah, I. M. W.; Sensoy A.; Kang, S. H. (Elsevier B.V., 2017)
      This paper investigates the time-varying equicorrelations and risk spillovers between crude oil, gold and the Dow Jones conventional, sustainability and Islamic stock index aggregates and 10 associated disaggregated Islamic ...
    • Non-cooperative joint replenishment under asymmetric information 

      Körpeoğlu, E.; Şen, A.; Güler, K. (Elsevier, 2013)
      We consider jointly replenishing n ex-ante identical firms that operate under an EOQ like setting using a non-cooperative game under asymmetric information. In this game, each firm, upon being privately informed about its ...
    • Non-Markovian dynamics in ultracold Rydberg aggregates 

      Genkin, M.; Schönleber, D. W.; Wüster, S.; Eisfeld, A. (Institute of Physics Publishing Ltd., 2016)
      We propose a setup of an open quantum system in which the environment can be tuned such that either Markovian or non-Markovian system dynamics can be achieved. The implementation uses ultracold Rydberg atoms, relying on ...
    • Probing nanoscale domains of J-Aggregates deposited on a mica surface 

      Özçelik, S.; Demir, M. M.; Birkan, B. (American Chemical Society, 2004)
      J-aggregates of 1,1′,3,3′-tetraethyl-5,5′,6,6′- tetrachlorobenzimidazolocarbocyanine (TTBC) were deposited on a mica surface and probed by atomic force microscopy operated at tapping mode in air. Optical spectra showed ...
    • Rydberg aggregates 

      Wüster S.; Rost J.-M. (Institute of Physics Publishing, 2018)
      We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy transport through collective eigenstates, considering isolated atoms or assemblies embedded within clouds of cold ground-state atoms. We ...
    • Tunable plexcitonic nanoparticles: a model system for studying plasmon-exciton interaction from the weak to the ultrastrong coupling regime 

      Balci, S.; Kucukoz, B.; Balci, O.; Karatay, A.; Kocabas, C.; Yaglioglu, G. (American Chemical Society, 2016)
      Controlling the number of dye molecules on metallic nanoparticles, which in turn affects the magnitude of Rabi splitting energy, is crucial for obtaining hybrid metal core–organic shell nanoparticles with tunable optical ...
    • Ultra hybrid plasmonics: Strong coupling of plexcitons with plasmon polaritons 

      Balci, S.; Kocabas, C. (OSA - The Optical Society, 2015)
      We report a ternary-coupled plasmonic system consisting of excitons of J-aggregated dye, localized surface plasmon polaritons of Ag nanoparticles, and propagating surface plasmon polaritons of continuous Ag film. J-aggregate ...
