Richards model, Gompertz model, and logistic model are widely used to describe growth model of a population. The Richards growth model is a modification of the logistic growth model. In this paper, we present a new modified logistic growth model. The

In this present paper, a discrete age-structured model of tuberculosis (TB) transmission is formulated and analyzed. The existence and stability of the model equilibriums are discussed based on the basic reproduction ratio. A sensitivity analysis of

In this study, we present a mathematical model of malaria transmission with a seasonality effect to describe the dynamics of the infection. In the absent seasonality effect, we prove the local stability of the malaria-free equilibrium point. The para

The complement metric dimension is one of the development of the metric dimension concept. The aim of this research is to determine the complement metric dimension of the joint graph of two connected graphs G and H, denoted by dim¯(G+H). The results

The complement metric dimension of graph is one of the recent topics in graph theory. The concept came from the metric dimension which is a topic that has developed very rapidly. The complement metric dimension of graph G is denoted by dim¯(G). The

Some concepts in graph theory are resolving set, dominating set, and dominant metric dimension. A resolving set of a connected graph [Formula: see text] is the ordered set [Formula: see text] such that every pair of two vertices [Formula: see text] h

In this work, we present a model dynamic of malaria disease transmission in Papua province, Indonesia. The parameters of the model are estimated based on the monthly cumulative data of malaria cases in the Papua province in 2018. We use the least-squ
