Modeling the Effect of Binding Kinetics in Spatial Drug Distribution in the Brain
(Hindawi, 2021-07-05)A 3-dimensional mathematical model is developed to determine the effect of drug binding kinetics on the spatial distribution of a drug within the brain. The key components, namely, transport across the blood-brain barrier ... -
Modeling the within-host co-infection of influenza A virus and pneumococcus
(Elsevier, 2018)In this paper a nonlinear mathematical model for a within-host co-infection of influenza A virus and pneumococcus is investigated. Conditions that explain the relations amid RIP and its relationship to the global asymptotic ... -
Modeling Traffic Flow on Multi-Lane Road: Effects ofLane-Change Manoeuvres Due to an On-ramp
(Global Journal of Pure and Applied Mathematics, 2018)Traffic breakdown is the main cause of vehicle traffic congestion in our multi-lane roads due to highway bottlenecks such as lane-drops, on and off-ramps. In this study the three phase traffic flow theory is outlined and ... -
