Coin, Dice and Diffusion Excel Models
These four excel sheets show the different things you can do with the use
of simple mathematical calculations and excel. We can make the computer
randomly choose between two conditions. We also made a diffusion model that
represented diffusion using both numbers and colors.
Durham Population Model
This model uses different constants and variables to show the change in
population of Durham over time.
Simple Population Model
This model uses the equation "HAVE = HAD + CHANGE" to model the graph of
Rabbits with Competition Model
We made a slider bar for both the rabbits' birth fraction as well as the
competition. As you drag the slider, you can see the change in the shape of
the graph that is created. This Vensim model creates a visual for what factors
go into determining the population of wolves and rabbits in a given
environment. This model also uses carrying capacity to make the model more
This website shows the spread of the bubonic plague using both an
AgentCubes model as well as a Vensim model. To make it easier to show in one
screen, my partner and I had to adjust the time steps making them differ from
the incubation period of the bubonic plague in real life. We found a variety
of different results in the population by changing different factors like
recovery fraction, death fraction and the spread probability.
Office Ethics Project
We were given a situation where we had to write how we would handle it based
on what we had learned in the Office Ethics lesson.
S.I.R Agent Model
This is a simple SIR model of disease progression in a population. If a
healthy person is next to a sick person, there is a percent chance the healthy
person changes into a sick person. Healthy people move randomly in the world.
Sick people move randomly in the world but slower. A counter counts the number
of different people.
