Harmonic Stability in Power Electronic-Based Power Systems: Concept, Modeling, and Analysis
IEEE Transactions on Smart Grid, 2019 The large-scale integration of power electronic-based systems poses new challenges to the stability and power quality of modern power grids. The wide timescale and frequency-coupling dynamics of electronic power converters tend to bring in harmonic ...

The harmonic mean p-value for combining dependent tests
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The widespread use of Bonferroni correction encumbers the scientific process and wastes opportunities for discovery presented by big data, because it discourages exploratory analyses by overpenalizing the total number of statistical tests ...

Harmonic Index and Harmonic Polynomial on Graph Operations [PDF]
Symmetry, 2018 Some years ago, the harmonic polynomial was introduced to study the harmonic topological index. Here, using this polynomial, we obtain several properties of the harmonic index of many classical symmetric operations of graphs: Cartesian product, corona product, join, Cartesian sum and lexicographic product.
