Model ini merupakan modifikasi model konsentrasi Dilantin yang sebelumnya one-compartement of repeated dose menjadi two-compartment repeated dose.
Compartment yang digunakan dalam pemodelan ini adalah dilantin in digestive system dan dilantin in plasma. Berdasarkan model ini, dapat diketahui konsentrasi dan volume dilantin di sistem pencernaan dan plasma darah hingga akhirnya dilantin tereliminasi dari tubuh.

Spring, 2020: in the midst of on-line courses, due to the pandemic of Covid-19.

With the onset of the Covid-19 coronavirus crisis, we focus on SIRD models, which might realistically model the course of the disease.

We start with an SIR model, such as that featured in the MAA model featured in
https://www.maa.org/press/periodicals/loci/joma/the-sir-model-for-spread-of-disease-the-differential-equation-model

Without mortality, with time measured in days, with infection rate 1/2, recovery rate 1/3, and initial infectious population I_0=1.27x10-4, we reproduce their figure

With a death rate of .005 (one two-hundredth of the infected per day), an infectivity rate of 0.5, and a recovery rate of .145 or so (takes about a week to recover), we get some pretty significant losses -- about 3.2% of the total population.

This is a systems model that allows groups of professionals to discuss 'prevention at scale' opportunities and the implications of numbers 'needed to treat' in any local population. In terms of public health interventions this equates to reach, compliance and efficacy, which are usually lower than one might suspect.
