Trade Flow and Nation Brand Distance: A Structural Gravity Model Approach
Published 2021“…The empirical findings shows that NBD influence both export and import volume in which less distant countries in term of nation brands are able to overcome the negative effect of geographical distance which can stimulates the export mainly and import flow to some extent. The results on the impact of NBD on FTA and trade flows provides some interesting insights as the there is a negative and significant moderation impact of NBD on the relationship between FTA and both export and import volume which suggest that a decrease of NBD will increase the effect of FTA on trade flow. …”

Polarimetric SAR Speckle Reduction by Hybrid Iterative Filtering
Published 2020“…An expression that takes into account the following important numerical considerations is proposed. 1) The variability of the pixel is measured by coefficient variation (CV) rather than the variance. 2) The statistics are computed using non-local neighborhood instead of local square one. 3) A new normalizing function (i. e. hyperbolic tangent) is implemented. 4) The dynamic of range of b k is increased by multiplying the CVs of the filtered and the originals images. …”
