    • Consensus as a Nash equilibrium of a dynamic game 

      Niazi, Muhammad Umar B.; Özgüler, Arif Bülent; Yıldız, Aykut (IEEE, 2016)
      Consensus formation in a social network is modeled by a dynamic game of a prescribed duration played by members of the network. Each member independently minimizes a cost function that represents his/her motive. An integral ...
    • Coordination of staffing and pricing decisions in a service firm 

      Serel, D. A.; Erel, E. (John Wiley & Sons, 2008)
      Customer demand is sensitive to the price paid for the service in many service environments. Using queueing theory framework, we develop profit maximization models for jointly determining the price and the staffing level ...
    • Cross-Term free based bistatic radar system using sparse least squares 

      Sevimli, R.A.; Cetin, A.E. (SPIE, 2015)
      Passive Bistatic Radar (PBR) systems use illuminators of opportunity, such as FM, TV, and DAB broadcasts. The most common illuminator of opportunity used in PBR systems is the FM radio stations. Single FM channel based PBR ...
    • Deconvolution using projections onto the epigraph set of a convex cost function 

      Tofighi, Mohammad; Bozkurt, Alican; Köse, K.; Çetin, Ahmet Enis (IEEE, 2014)
      A new deconvolution algorithm based on making orthogonal projections onto the epigraph set of a convex cost function is presented. In this algorithm, the dimension of the minimization problem is lifted by one and sets ...
    • Electromagnetic imaging of three-dimensional dielectric objects with Newton minimization 

      Etminan, Aslan; Sadeghi, Alireza; Gürel, Levent (IEEE, 2014)
      We present a general framework for detecting the shape and electrical properties of unknown objects by using the Newton minimization approach for solving inverse-scattering problems. This procedure is performed by evolving ...
    • Projection-based wavelet denoising [lecture notes] 

      Cetin, A. E.; Tofighi M. (Institute of Electrical and Electronics Engineers Inc., 2015)
      In this lecture note, we describe a wavelet domain denoising method consisting of making orthogonal projections of wavelet (subbands) signals of the noisy signal onto an upside down pyramid-shaped region in a multidimensional ...
    • Projections onto convex sets (POCS) based optimization by lifting 

      Çetin, A. Enis; Bozkurt, Alican; Günay, Osman; Habiboglu, Yusuf Hakan; Köse, K.; Onaran, İbrahim; Tofighi, Mohammad; Sevimli, Rasim Akın (IEEE, 2013)
      A new optimization technique based on the projections onto convex space (POCS) framework for solving convex and some non-convex optimization problems are presented. The dimension of the minimization problem is lifted by ...
    • Projections onto the epigraph set of the filtered variation function based deconvolution algorithm 

      Tofighi, M.; Çetin, Ahmet Enis (IEEE, 2017)
      A new deconvolution algorithm based on orthogonal projections onto the hyperplanes and the epigraph set of a convex cost function is presented. In this algorithm, the convex sets corresponding to the cost function are ...
    • Shape reconstruction of three-dimensional conducting objects via near-field measurements 

      Etminan, Aslan; Gürel, Levent (IEEE, 2014)
      A general framework for the shape reconstruction of conducting objects is presented with the Newton minimization approach. Using a fully numerical method, the initial-guess object is evolved to reconstruct the target. The ...
    • Successive cancelation approach for doppler frequency estimation in pulse doppler radar systems 

      Soğancı, Hamza; Gezici, Sinan (IEEE, 2010)
      In this paper, a successive cancelation approach is proposed to estimate Doppler frequencies of targets in pulse Doppler radar systems. This technique utilizes the Doppler domain waveform structure of the received signal ...
    • Target detection using sparsity based deconvolution in passive bistatic radars 

      Arslan, M.T.; Tofighi, M.; Cetin, A.E. (Institute of Electrical and Electronics Engineers Inc., 2015)
      We introduce a sparsity based deconvolution scheme to improve the range resolution of passive bistatic radar (PBR) systems. The two-dimensional matched filter output of a PBR system is further analyzed as a deconvolution ...
