    Matthew Donahue, of The University of Tulsa, gave a talk, "Tulsa's Next Top Model," at the 30 March 2019, Spring MAA Oklahoma-Arkansas Section Meeting about hosting the forthcoming SCUDEM IV 2019 event on 9 November 2019 at his school. Several faculty asked about how the...

  2. 7-011-Text-T-CoupledSystemLaplace

    31 Mar 2019 | Technique Narratives | Contributor(s): Mitaxi Mehta

    Differential equations and Laplace transforms are an integral part of control problems in engineering systems. However a clear explanation of the relationship of Laplace transforms with the differential equation formalism is difficult to find for coupled differential equations. Here we describe...

  6. 1-109-S-EmployeeAttrition

    25 Mar 2019 | Modeling Scenarios | Contributor(s): Lyle Clifford Smith

    This scenario models the loss of employees and the employer's attempt to retain them through stock options. This is intended for introductory students and is paired well with exponential growth/decay material. We also introduce the 5% rule to sort possible factors into assumptions and...

  7. 1-109-T-EmployeeAttrition

    25 Mar 2019 | Modeling Scenarios | Contributor(s): Lyle Clifford Smith

    This scenario models the loss of employees and the employer's attempt to retain them through stock options. It most naturally is solved with a first-order linear decay model with two populations. This is intended for introductory students and is paired well with exponential growth/decay...

  8. 5-005-Text-T-StiffDifferentialEquations

    05 Mar 2019 | Technique Narratives | Contributor(s): Kurt Bryan

    This material introduces the topic of ``stiffness'' for a system of ordinary differential equations (ODE's), through a series of examples.Stiffness is a property that a system of ODE's may possess that make it difficult to solve numerically with standard methods, and it is a...

  10. 1-125-T-DiceyPopulations

    04 Mar 2019 | Modeling Scenarios | Contributor(s): Brian Winkel

    We offer students an opportunity to generate unique data for their team on a death and immigration model using 12 and 20 sided dice and then pass on the data to another student team for analysis with a model they built. The key is to recover the parameters and try to explain how the simulation...
