The constructed based on development in which monomolecular monocyclic. show value Basic Reproduction Number (BRN) 0 transmission. BRN computed from largest eigenvalue next generation matrix model. result shows region where greater than one there single stable endemic equilibrium. However, less equilibrium becomes unstable....

The differential transformation method (DTM) is a semi-analytical numerical technique which depends on Taylor series and has application in many areas including Biomathematics. aim of this paper to employ the solve system non-linear equations for dengue transmission mathematical model. Analytical solutions are determined results compared that Runge-Kutta method. We found good agreement between DTM

An increasing number of world population leads to an increase need food. However, plant disease can reduce the production and quality Therefore, understanding dynamics is important as it provide insightful knowledge on transmission. A mathematical model be used investigate analyse effect control strategies. In this paper, we develop a deterministic where divided into five compartments: Susceptible, Exposed, Infection, Post-Infectious (Removed), Protected. We include preventive curative...

In this paper we formulate a model of dengue fever transmission by considering the presence asymptomatic and symptomatic compartments. The takes form as system differential equations representing host-vector SIR (Susceptible – Infective -Recovered) disease transmission. It is assumed that both host vector populations are constant. also reinfection recovered hosts possible due to wanning immunity in human body. We analyze determine qualitative behavior solution use concept effective basic...

Some numerical simulation are also given to illustrate our analytical results.

Plant cultivation in the tropics can make it easier for farmers to determine when planting season is good, with hope of satisfying production. Unfortunately, changing seasons at this time are irregular. The low productivity caused by various things, one which occurrence plant diseases pathogens and spread through insects.
