1119SDairyFarming
20 Sep 2020  Modeling Scenarios  Contributor(s): Rob Krueger
A simple first order population growth model is presented. The challenge is to produce a final differential equation which is the result of the difference or ratio of birth and death rates. This ratio is not immediately intuitive.

Meeting Software Platforms for SCUDEM V 2020 Teams
19 Sep 2020  General Resources  Contributor(s): Brian Winkel
This is a brief introduction to some Meeting Software Platforms for SCUDEM V 2020 Teams with links and a few comments. However, it is up to the individuals, what their institution provides, and personal choices, as to which platform they use.

9002SGroundWaterFlow
31 Aug 2020  Modeling Scenarios  Contributor(s): Jeremy Christman, Michael Karls, Kenneth H. Luther
The goals of this project are to compare a conceptual onedimensional groundwater flow model to observations made in a laboratory setting, and to discuss the differences. We derive the initial groundwater flow equation, and guide students through a solution. We describe the laboratory set up and...

Questions and Answers from 13 August 2020 SIMIODE Panel and Q&A on Remote Teaching Modules
14 Aug 2020  General Resources  Contributor(s): Corban Harwood, Audrey Malagon, Therese Shelton, Patrice Geary Tiffany, Brian Winkel
We enclose the Chat questions and panel responses from the 13 August 2020 SIMIODE Panel and Q&A on Remote Teaching Modules. We thank the participants for stimulating questions.

1096SOpAmpDifferentiator
09 Aug 2020  Modeling Scenarios  Contributor(s): Virgil Ganescu
In this validationoriented setup, the output waveform (function) of a operational amplifier type of differentiator circuit is determined analytically from the first order governing ordinary differential equation and the results are compared with the data acquired from analyzing the numerical...

Numerical Simulation of Ebola Outbreak
01 Aug 2020  Presentations
The Ebola virus disease is a serious infectious disease with the highest mortality rate that is considered as one of the most contagious diseases. Our goal is to construct a mathematical model to devise the optimal Ebola outbreak simulation, and through a numerical simulation predict the behavior...

This PowerPoint is for the Panel and Q&A Presentation on Remote Teaching Modules to be held at 4 PM Eastern US Time on Thursday, 13 August 2020. This is with reference to materials found at https://www.simiode.org/modules.

Modeling Guide and Resources for Student and Coach
25 Jul 2020  General Resources  Contributor(s): William Clark, Anthony Stefan
This is a Modeling Guide for SCUDEM V 2020 and a set of Useful Resources prepared by Anthony Stefan, Florida Institute of Technology, Melbourne FL USA and William Clark, Dixie State University, St. George UT USA serving as Science Gateway Community Institute and SIMIODE Summer 2020...

3105SFrequencyResponse
22 Jul 2020  Modeling Scenarios  Contributor(s): Brian Winkel
We describe the frequency response to a second order differential equation with a driving function as the maximum steady state solution amplitude and perform some analyses in this regard.

3034TCarSuspensions
14 Jul 2020  Modeling Scenarios  Contributor(s): Therese Shelton, Brian Winkel
In this modeling activity, students examine the springmassdashpot that is part of a car suspension. We model a "quarter car'', meaning a single wheel, and compare effects of different masses, spring constants, damping coefficients, and the angle at which the assembly is...

3034SCarSuspensions
14 Jul 2020  Modeling Scenarios  Contributor(s): Therese Shelton, Brian Winkel
We examine the springmassdashpot that is part of a car suspension, how the ride is related to parameter values, and the effect of changing the angle of installation. We model a "quarter car'', meaning a single wheel.

3027SBobbingDropping
10 Jul 2020  Modeling Scenarios  Contributor(s): Brian Winkel
We present two exercises from a differential equations text in which we ask students to model (1) falling object experiencing terminal velocity and (2) bobbing block of wood in liquid. We model the motion using Newton's Second Law of Motion and Archimedes' Principle.

Laplace One Liner
04 Jul 2020  General Resources  Contributor(s): Brian Winkel
We offer a short Mathematica file in which we demonstrate the step by step commands for solving a second order, linear, constant coefficient, ordinary differential equation using Laplace Transforms and then we condense the entire set of instructions into one line of code  hence the name one liner.

SCUDEM  SIMIODE Challenge Using Differential Equation Modeling is an annual event for student teams around the globe.We post here the Judges Rubric used to score student submissions.

1088SRoomTemperature
15 Jun 2020  Modeling Scenarios  Contributor(s): Tracy Weyand
Students will analyze temperature variations in a room using Newton's Cooling Law. In this model, the only influence on the indoor temperature is the (oscillating) outdoor temperature (as we assume the heating/cooling system is broken). The main goal of this project is for students to set up...

1136SMarriageAge
11 Jun 2020  Modeling Scenarios  Contributor(s): Tracy Weyand
Students will build and analyze a model of the fraction of people who are married (for the first time) by a certain age. This model comes from a paper by Hernes and, in this project, is compared to another model used by Coale.These models are firstorder ordinary differential equations (which...
