This project introduces the concept of differential equations with delay, the so called delay differential equations (DDEs). These differential equations depend on past history (at previous times),and are therefore used ...

TB is an air born communicable infectious disease caused by MBT. In Ethiopia TB is the major cause of morbidity and mortality. In this thesis, we have considered a nonlinear dynamical system. We divide the total population ...

In this paper, Adomian decomposition method (ADM) and some of its modification will be introduced to obtain the solution convergent towards an accurate solution of nonlinear Partial DifferentialEquations. Theseefficientmod ...

In this paper, we present approximate and exact solution of initial value problems of ordinary differential equations (Odes) by using Differential Transform method (DTM). The concept of differential transform and some properties ...

In this study, we will discuss the Sumudu transform method [STM] to solve the ordinary differential equation of constant coefficient and its application in different areas such as in physics followed by the application to ...
