    • Adaptive tracking of narrowband HF channel response 

      Arikan, F.; Arıkan, Orhan (Wiley-Blackwell Publishing, 2003)
      Estimation of channel impulse response constitutes a first step in computation of scattering function, channel equalization, elimination of multipath, and optimum detection and identification of transmitted signals through ...
    • Framework for online superimposed event detection by sequential Monte Carlo methods 

      Urfalıoğlu, Onay; Kuruoğlu, E. E.; Çetin, A. Enis (IEEE, 2008-03-04)
      In this paper, we consider online seperation and detection of superimposed events by applying particle filtering. We concentrate on a model where a background process, represented by a 1D-signal, is superimposed by an ...
    • An inventory problem with two randomly available suppliers 

      Gürler, Ü.; Parlar, M. (Institute for Operations Research and the Management Sciences, 1997)
      This paper considers a stochastic inventory model in which supply availability is subject to random fluctuations that may arise due to machine breakdowns, strikes, embargoes, etc. It is assumed that the inventory manager ...
    • Matrix-geometric solutions of M/G/1-type Markov chains: A unifying generalized state-space approach 

      Akar, N.; Oǧuz, N.C.; Sohraby, K. (1998)
      In this paper, we present an algorithmic approach to find the stationary probability distribution of M/G/1-type Markov chains which arise frequently in performance analysis of computer and communication networ ks. The ...
    • Neural networks based online learning 

      Ergen, Tolga; Kozat, Süleyman Serdar (IEEE, 2017)
      In this paper, we investigate online nonlinear regression and introduce novel algorithms based on the long short term memory (LSTM) networks. We first put the underlying architecture in a nonlinear state space form and ...
    • Observer based control of chaos 

      Solak, Ercan; Morgül, Ömer; Ersoy, Umut (IEEE, 1997-08)
      In this work we consider the control of forced chaotic oscillators. To obtain any desirable behavior, the system parameters are effectively modified using state feedback. The system states used in the feedback are estimated ...
    • On algebraic properties of general proper decentralized systems 

      Yu, R.; Sezer, M. E.; Gao, W. (Elsevier, 1993)
      The new concepts of the decentralized output feedback variable polynomial, the decentralized output feedback cycle index of general proper systems, and the geometric multiplicities of decentralized fixed modes are introduced. ...
    • Online distributed nonlinear regression via neural networks 

      Ergen, Tolga; Kozat, Süleyman Serdar (IEEE, 2017)
      In this paper, we study the nonlinear regression problem in a network of nodes and introduce long short term memory (LSTM) based algorithms. In order to learn the parameters of the LSTM architecture in an online manner, ...
    • Parameter identification for partially observed diffusions 

      Dabbous, T.E.; Ahmed, N.U. (Kluwer Academic Publishers-Plenum Publishers, 1992)
      In this paper, we consider the identification problem of drift and dispersion parameters for a class of partially observed systems governed by Ito equations. Using the pathwise description of the Zakai equation, we formulate ...
    • Sentioscope: a soccer player tracking system using model field particles 

      Baysal, S.; Duygulu, P. (Institute of Electrical and Electronics Engineers, 2016)
      Tracking multiple players is crucial to analyze soccer videos in real time. Yet, rapid illumination changes and occlusions among players who look similar from a distance make tracking in soccer very difficult. Particle-f ...
    • Superimposed event detection by sequential Monte Carlo methods 

      Urfalıoğlu, O.; Kuruoğlu, E. E.; Çetin, A. Enis (IEEE, 2007)
      In this paper, we consider the detection of rare events by applying particle filtering. We model the rare event as an AR signal superposed on a background signal. The activation and deactivation times of the AR-signal are ...
    • Supporting hurricane inventory management decisions with consumer demand estimates 

      Morrice, D. J.; Cronin, P.; Tanrisever, F.; Butler, J. C. (Elsevier B.V., 2016)
      Matching supply and demand can be very challenging for anyone attempting to provide goods or services during the threat of a natural disaster. In this paper, we consider inventory allocation issues faced by a retailer ...
    • Testing communication protocols 

      Naik, K.; Sarıkaya, B. (1992)
