  • A new classification approach using discriminant functions 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (INST INFORMATION SCIENCE, 2005)
    In this study, an approach involving new types of cost functions is given for the construction of discriminant functions. Centers of mass, not specified a priori, around feature vectors are clustered using cost function. ...
  • A system theoretic approach to array processing 
    Demirkol, Aşkın; Demir, Zafer; Erol, Emre (NATL INST OPTOELECTRONICS, 2015)
    In this paper, utilizing system theoretic concepts a sound, rigorous theory of array processing is established which leads to several new results. MUSIC, MIN-NORM, ESPRIT, and PISARENKO used for both spatial and temporal ...
  • A unifying approach to track-to-track correlation for multisensor fusion for multiple targets 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (NATL INST OPTOELECTRONICS, 2015)
    In this paper, a global modeling approach was proposed for multi sensor fusion problems. Once the global model was investigated considering the data association and fusion, it is adapted to track to track correlation problem ...
  • An ambiguity function aided target density function for radar imaging 
    R. F. Cinar; Demirkol, Aşkın; Demir, Zafer (NATL INST OPTOELECTRONICS, 2015)
    This paper investigates a new approach to target density functions for active sensor imaging. The data obtained from a phased array radar system is processed by the newly developed technique. In order to reconstruct the ...
  • Angle density functions for active sensor imaging 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (INST ENGINEERING TECHNOLOGY-IET, 2009)
    A new target density function (TDF) is proposed for active sensor imaging. The TDF, called the angle density function, is studied by utilising the angular distribution of targets at a fixed range. Active sensor imaging ...
  • Estimation of target density functions via range-angle beamforming 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (TAYLOR & FRANCIS LTD, 2009)
    This paper considers estimation of target density functions in 'range-angle' coordinates using two beamforming techniques. The distribution of the target densities in range-angle coordinates is estimated utilizing several ...
  • LECTURE NOTES IN COMPUTER SCIENCE 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (SPRINGER-VERLAG BERLIN, 2005)
    In this paper, a new Target Density Function(TDF) is theorized to image the radar targets by a new estimation algorithm. TDF is represented in a specified manner. This method is developed by inspiring of ambiguity functions. ...
  • LECTURE NOTES IN COMPUTER SCIENCE 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (SPRINGER-VERLAG BERLIN, 2006)
    In this work, four alternative algorithms for Classification/Discrimination are described which we have developed recently. These are believed to have several advantages over the previous ones via the introduction of a new ...
  • The Influence of Micro- and Nano-Filler Content on the Mechanical Properties of Epoxy Composites 
    Özsoy, Mehmet İskender; Demirkol, Aşkın; Mimaroğlu, Abdullah; Ünal, Hüseyin; Demir, Zafer (ASSOC MECHANICAL ENGINEERS TECHNICIANS SLOVENIA, 2015)
    In this study, the influence of micro-and nano-filler content on the mechanical properties of epoxy composites was studied. The matrix material is epoxy; the micro-fillers are Al2O3, TiO2 and fly ash added in 10 wt% to 30 ...
