6010SSocialCampaigns
23 Sep 2018  Modeling Scenarios  Contributor(s):: Hyunsun Lee
Mathematical epidemic models are crucial tools to understand, analyze, predict, and control infectious diseases. The SusceptibleInfectedRecovered (SIR) model is a basic compartment model, describing how an infectious disease propagates through a population. The problem is formulated as a...

6024SDronePackageDelivery
18 Sep 2018  Modeling Scenarios  Contributor(s):: Eric Stachura, Robert Krueger
In this scenario, students will begin by carefully reading through the problem statement and uncovering which information is useful. Students will derive a system of differential equations which describe the flight path of a drone delivering a package. Techniques used to derive the analytical...
