A Study on Semi-directed Graphs for Social Media Networks

International Journal of Computational Intelligence Systems, 2021
In the literature of graph theory, networks are represented as directed graphs or undirected graphs and a mixed of both combinations. In today's era of computing, networks like brain and facebook that do not belong to any of the mentioned networks ...

Mixed Moore Cayley Graphs [PDF]

Journal of Interconnection Networks, 2017
The degree-diameter problem seeks to find the largest possible number of vertices in a graph having given diameter and given maximum degree. There has been much recent interest in the problem for mixed graphs, where we allow both undirected edges and directed arcs in the graph.

Exploring Ways to Improve Elementary School Statistics Education Through Analysis of Middle School Social Studies Textbooks: Focusing on Statistical Graph Teaching

Journal of Educational Research in Mathematics, 2020
In this study, in order to explore ways that statistical graphs teaching in elementary mathematics education can be improved, first, the types of statistical graphs that appear in middle school social textbooks were examined, and second, the ...

Research and Application of Hypernetwork Energy

Jisuanji kexue yu tansuo, 2021
Graph energy plays an important role in research of graph theory. Graph energy and many other similar variants have been applied in many other types of graphs, e.g., undirected graphs, oriented graphs, mixed graphs, and so on.

Best Graph Type to Compare Discrete Groups: Bar, Dot, and Tally

Frontiers in Psychology, 2021
Different graph types might differ in group comparison due to differences in underlying graph schemas. Thus, this study examined whether graph schemas are based on perceptual features (i.e., each graph has a specific schema) or common invariant ...

GRAPH mixing

, 2018
In the era of gravitational wave (GW) detection from astrophysical sources by LIGO/VIRGO, it is of great importance to take the quantum gravity effect of graviton-photon (GRAPH) mixing in the cosmic magnetic field to the next level. In this work, we study such an effect and derive for the first time perturbative solutions of the linearized equations of

On Mixed Metric Dimension of Rotationally Symmetric Graphs

IEEE Access, 2020
A vertex u ∈ V(G) resolves (distinguish or recognize) two elements (vertices or edges) v, w ∈ E(G)UV(G) if dG(u, v) ≠ dG(u, w) . A subset Lm of vertices in a connected graph G is called a mixed metric generator for G if every two ...
