![In tracking the propagation of a disease, a population can be divided into 3 groups: the portion that is susceptible, S(C), the portion that is infected, Ft), and the portion that is recovering, R(t). Each of these will change according to a differential equation: R= so that the portion of the population that is infected is increasing in proportion to the number of people that contract the disease, and decreasing as a proportion of the infected people who recover. If we introduce the vector y [S F RIT, this can be written in matrix form as y,-Ay. susceptible If one of the solutions is y = xi + 600 e-t/a x2 + 500 e-tic X3, where xi-[0 0 50,000]T, x: [0-1 1]T, and x3-[b 63-81]T, what are the values of a, b, and c?](http://img.homeworklib.com/questions/3ec5f3d0-5bb9-11ea-a099-43f97f569799.png?x-oss-process=image/resize,w_560)

m #2: In tracking the propagation of a disease, a population can be divided into 3 groups: the portion that is susceptible, S), the portion that is infected, F(t), and the portion that is recovering, R(t). Each of these will change according to a differential equation: S' F =-5 S F R - so that the portion of the population that is infected is increasing in proportion to the number of susceptible people that contract the disease, and decreasing as...

Question 1. First, we study a model for a disease which spreads quickly through a population. The rate of new infections at time t is proportional to the number of people who are currently infected at time t, and the number of people who are susceptible at time t. (a) Explain why I(t) satisfies the first-order ODE dI BI(N − 1) dt where ß > 0 is a constant. (b) Find the equilibrium solution(s) of the ODE (in terms of...

Consider a system of differential equations describing the progress of a disease in a population, given byF, ) for a vector-valued function F. In our particular case, this IS. where z(t) is the number of susceptible individuals at time t and y(t) is the number of infected individuals at time t. The number of individuals is counted in units of 1,000 individuals a) Find the nullclines (simplest form) of this system of differential equations. The x-nullcline is y 2/3 The...

Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...
