With the increasing marketization of electricity, residential users are gradually participating in various businesses power utility companies, and there more interactive adjustments between load, source, grid. However, participation large-scale has also brought challenges to grid companies carrying out demand-side dispatching work. The user load response is uneven, users’ behavioral characteris...

This paper proposes a two-step approach for characterizing the reservoir properties of the world’s largest non-associated gas reservoir. This approach integrates geological and petrophysical data and compares them with the field performance analysis to achieve a practical electrofacies clustering. Porosity and permeability prediction is done on the basis of linear functions, succeeding the elec...

This study compares the K-Means and two-step cluster analysis methods for clustering COVID-19 data. The dataset had 1,893,941 cumulative cases from January 2020 to October 2021. K-means resulted in eight clusters, while three grouped by nationality, occupation, patient type, risk group. These clusters were categorized based on age, gender, region of infection. Group 1 5,883 workers infected com...

Sparse subspace clustering (SSC) relies on sparse regression for accurate neighbor identification. Inspired by recent progress in compressive sensing, this paper proposes a new scheme SSC via two-step reweighted $\ell _{1} $ -minimiza...
