In the research of fractal cities, the fractal dimension is very important. It is used to describe the fractal character of the city. The authors have designed two approaches to calculate the fractal dimension by the box-counting method through an example of Beijing, which are called the vector...
Identifying and matching features in these images enables the calculation of a point cloud, which is further used to generate a surface model. Post-processing techniques, including noise reduction, smoothing, and repair, are applied to the surface model to improve the accuracy of the 3D model38,...
This enables the estimation of the geometry-induced uncertainties in the calculation of molecular diffusion constants obtained by FRAP. The employed numerical method of PSE (23) is crucial in doing so, because it avoids many of the problems that grid-based methods have in complex geometries, and...
Forty retinal vasculature images from publicly available dataset were subjected to four variations of box-counting FD algorithm. Different positions of box-grid were found to significantly affect the measurement of FD (p < 0.0001, d = 0.746) due to non-identical vessels captured for measurement. ...
Previous study indicates that provided uniformly refined cubic fluid cells, the calculation error of the CFD–DEM method tends to first decrease with a finer grid size and then increase when \(L_{f}/D_{\text {avg}} < 3\) [68], in which \(L_{f}\) is the length of fluid cells ...

ground plane will not be achieved. The calculation for the transfer line is done with AWR microwave software office and TX-line tools. At the first stage, we have designed the antenna over the FR4 substrate withμ=1,εr=4.3and thickness of 1.6 mm. In Fig.1, the designing steps are ...
As an important link in the complex system engineering project of open pit mining, the quality of the boundary determines the performance of the project to a large extent. However, changes in economic indicators may raise doubts about the optimality of m
