• State-Space Identification Of Switching Linear Discrete Time-Periodic Systems With Known Scheduling Signals 

      Uyanik, Ismail; Hamzacebi, Hasan; Ankarali, M. Mert (2019)
      In this paper, we propose a novel frequency domain state-space identification method for switching linear discrete time-periodic (LDTP) systems with known scheduling signals. The state-space identification problem of linear ...
    • Statistical Learning Approaches In Diagnosing Patients With Nontraumatic Acute Abdomen 

      Zararsiz, Gokmen; Akyildiz, Hizir Yakup; Goksuluk, Dincer; Korkmaz, Selcuk; Ozturk, Ahmet (Tubitak Scientific & Technical Research Council Turkey, 2016)
      A quick evaluation is required for patients with acute abdominal pain. It is crucial to differentiate between surgical and nonsurgical pathology. Practical and accurate tests are essential in this differentiation. Lately, ...
    • Tomographic Reconstruction Of The Ionospheric Electron Density As A Function Of Space And Time 

      Erturk, Onur; Arikan, Orhan; Arikan, Feza (Elsevier Sci Ltd, 2009)
      Electron density distribution is the major determining parameter of the ionosphere. Computerized Ionospheric Tomography (CIT) is a method to reconstruct ionospheric electron density image by computing Total Electron Content ...
    • Total Electron Content Estimation With Reg-Est 

      Nayir, H.; Arikan, F.; Arikan, O.; Erol, C. B. (Amer Geophysical Union, 2007)
      Total Electron Content ( TEC) constitutes one of the key elements for observing the variable structure of the ionosphere. GPS provides a cost- effective alternative in TEC estimation through earth- based receivers. In this ...
    • Unsupervised Learning Of Allomorphs In Turkish 

      Can, Burcu (Tubitak Scientific & Technical Research Council Turkey, 2017)
      One morpheme may have several surface forms that correspond to allomorphs. In English, ed and d are surface forms of the past tense morpheme, and s, es, and ies are surface forms of the plural or present tense morpheme. ...
    • Wavelet Based Flickering Flame Detector Using Differential Pir Sensors 

      Erden, Fatih; Toreyin, B. Ugur; Soyer, E. Birey; Inac, Ihsan; Gunay, Osman; Kose, Kivanc; Cetin, A. Enis (Elsevier Sci Ltd, 2012)
      A Pyro-electric Infrared (FIR) sensor based flame detection system is proposed using a Markovian decision algorithm. A differential PIR sensor is only sensitive to sudden temperature variations within its viewing range and ...
    • Wideband Analysis Of Planar Scalable Antennas And Pec Bodies Using Cbfm 

      Koc, Sema Nur; Koksal, Adnan (Tubitak Scientific & Technical Research Council Turkey, 2016)
      In this paper, scattering and radiation from scalable planar bodies are investigated in a wide frequency band. Characteristic basis functions (CBFs) are utilized for this purpose with a different approach. The CBFs for the ...
