A Note on Estimation of Multi-Sigmoidal Gompertz Functions with Random Noise

open access: yesMathematics, 2019
The behaviour of many dynamic real phenomena shows different phases, with each one following a sigmoidal type pattern. This requires studying sigmoidal curves with more than one inflection point. In this work, a diffusion process is introduced whose mean

The Strong Resolving Graph and the Strong Metric Dimension of Cactus Graphs

open access: yesMathematics, 2020
A vertex w of a connected graph G strongly resolves two distinct vertices u,v∈V(G), if there is a shortest u,w path containing v, or a shortest v,w path containing u. A set S of vertices of G is a strong resolving set for G if every two distinct vertices
