    • 2D simultaneous localization and mapping for unmanned aerial vehicles 

      Kök, M.; Barshan, B. (2008)
      In this work, a 2D vision-based Simultaneous Localization and Mapping algorithm is developed for an Unmanned Aerial Vehicle flying at a constant altitude. We use visual features of images obtained from an on-board camera ...
    • A comparative study of map building techniques by processing sonar arc-maps 

      Kurt, A.; Barshan, B. (2005)
      In this study, four signal processing schemes regarding sonar sensor based map-building applications were compared. The newly proposed method, Directional Maximum is found to be successful in terms of reducing the innate ...
    • A comparative study on the processing of ultrasonic arc maps 

      Barshan, B. (2008)
      The directional maximum (DM) technique for processing ultrasonic arc maps is proposed and compared to previously existing techniques. The method processes ultrasonic arc maps directionally to extract the map of the environment ...
    • Directional processing of ultrasonic arc maps and its comparison with existing techniques 

      Barshan, B.; Altun, K. (2007)
      Directional maximum (DM) technique for processing ultrasonic arc maps (UAMs) is proposed and compared to existing techniques. It employs directional processing in extracting the map of the environment from UAMs. DM aims ...
    • Effective kernel mapping for OpenCL applications in heterogeneous platforms 

      Albayrak, Ömer Erdil; Aktürk, İsmail; Öztürk, Özcan (Institute of Electrical and Electronics Engineers, 2012-09)
      Many core accelerators are being deployed in many systems to improve the processing capabilities. In such systems, application mapping need to be enhanced to maximize the utilization of the underlying architecture. Especially ...
    • Employing active contours and artificial neural networks in representing ultrasonic range data 

      Altun, K.; Barshan, B. (2008)
      Active snake contours and Kohonen's self-organizing feature maps (SOM) are considered for efficient representation and evaluation of the maps of an environment obtained with different ultrasonic arc map (UAM) processing ...
    • Fault-tolerant topology generation method for application-specific network-on-chips 

      Tosun, S.; Ajabshir, V. B.; Mercanoglu, O.; Ozturk, O. (Institute of Electrical and Electronics Engineers, 2015)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Improving application behavior on heterogeneous manycore systems through kernel mapping 

      Albayrak, O. E.; Akturk, I.; Ozturk, O. (2013)
      Many-core accelerators are being more frequently deployed to improve the system processing capabilities. In such systems, application mapping must be enhanced to maximize utilization of the underlying architecture. Especially, ...
    • On a Problem of A. Eremenko 

      Ostrovskii, I. V. (Springer, 2005-05)
      Let Pmn, 0 < m < n− 1, be a polynomial formed by the first m terms of the expansion of (1 + z)n according to the binomial formula. We show that, if m, n→∞ in such a way that limm,n→∞ m/n = α ∈ (0, 1), then the zeros of ...
    • Space weather studies of IONOLAB group 

      Arikan, F.; Sezen, U.; Toker C.; Artuner, H.; Bulu, G.; Demir, U.; Erdem, E.; Arikan, O.; Tuna, H.; Gulyaeva, T. L.; Karatay S.; Mosna, Z. (Institute of Electrical and Electronics Engineers Inc., 2016)
      IONOLAB is an interdisciplinary research group dedicated for handling the challenges of near earth environment on communication, positioning and remote sensing systems. IONOLAB group contributes to the space weather studies ...
