Textbook Question
Chapter 18, Problem 29ICA
If a hot liquid in a container is left to cool, its temperature (T) [°C] will gradually approach room temperature. This model will have the form T = A + B emt. In this case, m will always be negative and its dimension will be inverse time. If it is not clear how to determine A and B, consider that T = A + B when t = 0, T = A as t approaches infinity.
You are to write a function named Cooling that will accept two parameters:
- Tr: Room temperature in degrees C
- TData: A two-row matrix containing measurements of a cooling liquid at various times. The first row contains the times of the measurements in minutes, and the second row contains the corresponding temperature measurements in degrees C
The function must perform the following operations:
- Plot the measured points.
- Determine an exponential model to fit the data.
- Add the exponential trendline to the graph.
- Add the trendline equation for the exponential model to the graph.
Example
Room Temperature: Tr = 30
Temperature Data: TData = [0.5 3 7 11; 85 48 35 33]

How long will the [delta t] process take? (time)
Please keep in mind that almost every variable is unknown! We are given no numbers and are instructed to generate a solution using the variables [ "R, M, g, I and H." ]
Target =
Find an equation that, if we could substitute numbers, would determine how long the process would take.
Newton's second law and torque seem to be relevant based on how the problem is written.

1. For the following concentration expressions, indicate whether they are uniform or nonuniform
and in how many dimensions (OD, 1D, 2D, or 3D), and steady or unsteady. Then for the following
control volume and origin, and table of constants, use Excel or Matlab to graph profiles that
show how concentration changes within the control volume and over time to a limit of 20 for
the following: C(x,0,0,0), C(0,y,0,0), C(0,0,z,0) and C(0,0,0,t). On each graph, show which
parameters are held constant, the CV boundaries, and the point where all four plots overlap.

I want to run several shocks in my calibrated DSGE model.
I want the shock “a” to happen at period 0, shock “b” at period 2 and shock “c” at period 5.
Also, I want to run a shock of 1 % to the variable “a”, 2 % to variable “b” and 10 % to variable “c”.
How would I write it in the Dynare code?
The model is log-linearized around the steady state and all endogenous variables are set at 0 at the steady state.
