Modeling export price of tea in Kenya: Comparison of artificial neural network and seasonal autoregressive integrated moving average
(Science Publishing Group, 2014-12-19)Agriculture sector is a key driver of economic growth in Kenya. It remains the main source of livelihood for the majority of the Kenyan people. Tea, coffee, and horticulture are the main agricultural exports in Kenya. ... -
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 ... -
