Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities

The World Economy, EarlyView.
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

Fractal Dimension of Color Fractal Images

IEEE Transactions on Image Processing, 2011
Fractal dimension is a very useful metric for the analysis of the images with self-similar content, such as textures. For its computation there exist several approaches, the probabilistic algorithm being accepted as the most elegant approach. However, all the existing methods are defined for 1-D signals or binary images, with extension to grayscale ...

APPROXIMATION WITH FRACTAL FUNCTIONS BY FRACTAL DIMENSION

Fractals, 2022
On the basis of previous studies, we explore the approximation of continuous functions with fractal structure. We first give the calculation of fractal dimension of the linear combination of continuous functions with different Hausdorff dimension. Fractal dimension estimation of the linear combination of continuous functions with the same Hausdorff ...
