    • Architectural viewpoints for global software development 

      Yildiz, B.M.; Tekinerdogan, B. (2011)
      Global Software Development (GSD) can be considered as the coordinated activity of software development that is not localized and central but geographically distributed. Designing an appropriate software architecture of a ...
    • Automated web services composition with the event calculus 

      Aydin O.; Kesim Cicekli, N.; Cicekli I. (2008)
      As the web services proliferate and complicate it is becoming an overwhelming job to manually prepare the web service compositions which describe the communication and integration between web services. This paper analyzes ...
    • Channel polarization: A method for constructing capacity-achieving codes 

      Arikan, E. (2008)
      A method is proposed, called channel polarization, to construct code sequences that achieve the symmetric capacity I(W) of any given binary-input discrete memoryless channel (B-DMC) W. The symmetric capacity I(W) is the ...
    • Foreword: 1st International Workshop on High Performance Computing for Big Data 

      Kaya, K.; Gedik, B.; Çatalyürek, U.V. (Institute of Electrical and Electronics Engineers Inc., 2015)
      The 1st International Workshop on High Performance Computing for Big Data (HPC4BD) is held on September 10, 2014 in concordance with 43rd International Conference on Parallel Processing (ICPP-2014). The workshop aimed to ...
    • Millimeter-wave scale metamaterials 

      Alici, K.B.; Ozbay, E. (2009)
      We review two metamaterial configurations, which are operating at the millimeter-wave scale, in terms of design, fabrication, and characterization. We observed both numerically and experimentally at around 100 GHz a narrow ...
    • Optimal measurement under cost constraints for estimation of propagating wave fields 

      Özçelikkale, A.; Ozaktas, H., M.; Arikan, E. (2007)
      We give a precise mathematical formulation of some measurement problems arising in optics, which is also applicable in a wide variety of other contexts. In essence the measurement problem is an estimation problem in which ...
    • A performance evaluation framework of a rate-controlled MPEG video transmission over UMTS networks 

      Akar, N.; Barbera, M.; Budzisz, L.; Ferrùs, R.; Kankaya, E.; Schembra, G. (IEEE, 2007)
      UMTS is designed to offer high bandwidth radio access with QoS assurances for multimedia communications. In particular, real-time video communications services are expected to become a successful experience under UMTS ...
    • Performance limits on ranging with cognitive radio 

      Dardari, D.; Karisan, Y.; Gezici, S.; D'Amico, A.A.; Mengali, U. (2009)
      Cognitive radio is a promising paradigm for efficient utilization of the radio spectrum due to its capability to sense environmental conditions and adapt its communication and localization features. In this paper, the ...
    • Piecewise smooth signal denoising via principal curve projections 

      Ozertem, U.; Erdogmus, D.; Arikan, O. (2008)
      One common problem in signal denoising is that if the signal has a blocky, in other words a piecewise-smooth structure, the denoised signal may suffer from oversmoothed discontinuities or exhibit artifacts very similar to ...
    • Semantic scene classification for image annotation and retrieval 

      Çavuş Ö.; Aksoy, S. (2008)
      We describe an annotation and retrieval framework that uses a semantic image representation by contextual modeling of images using occurrence probabilities of concepts and objects. First, images are segmented into regions ...
    • The shifting tides of academe: oscillation between hand and computer in architectural education 

      Şenyapili, B.; Basa Ý. (Springer Netherlands, 2006-09)
      There is a current vacillation in choosing hand or computer for design presentation in academia. Although the computer emerged as very powerful alternative presentation medium, it could not sweep away the hand totally. ...
    • Time delay estimation in cognitive radio systems 

      Kocak F.; Celebi H.; Gezici, S.; Qaraqe, K.A.; Arslan H.; Poor H.V. (2009)
      In cognitive radio systems, secondary users can utilize multiple dispersed bands that are not used by primary users. In this paper, time delay estimation of signals that occupy multiple dispersed bands is studied. First, ...
    • A wideband and a Wide-Beamwidth acoustic transducer design for underwater acoustic communications 

      Elmasli, I. C.; Köymen, H. (IEEE, 2007)
      This paper is concerned with the design of an efficient, wideband and a wide-beamwidth resonant acoustic transducer for high frequency use. The general transducer structure which has two back-to-back quarter wave thick 1-3 ...
