    • Investigation of ionospheric trend over Turkey using sliding window statistical analysis method 

      Deviren, M. N.; Arikan, F.; Arıkan, Orhan (IEEE, 2013)
      In this paper, variability of trend over Turkey is investigated statistically by Sliding Window Statistical Analysis (SWSA) method. First and second moment of the variability of ionospheric trend is calculated by SWSA ...
    • Investigation on the reliability of earthquake prediction based on ionospheric electron content variation 

      Akyol, Ali Alp; Arıkan, Orhan; Arıkan F.; Deviren, M. N. (ISIF, 2013-07)
      Due to lack of statistical reliability analysis of earthquake precursors, earthquake prediction from ionospheric parameters is considered to be controversial. In this study, reliability of earthquake prediction is investigated ...
    • İyonosfer TEİ verilerinin uzay-zamansal aradeğerlemesi 

      Yıldız, Aykut; Arıkan, Orhan; Arıkan, F. (IEEE, 2011-04)
      GPS sinyalleri iyonosferdeki elektron yoğunluğunun kestirilmesi için önemli bir bilgi kaynağıdır. Ancak, GPS alıcılarında sinyallerin kaydedilemediği durumlar olmaktadır. Bu kesinti sırasında iyonosfer elektron içeriğinin ...
