This journal entry is due on Tuesday, February 3 at midnight PST (Monday night/Tuesday morning). NOTE that the server records the time as Eastern Standard Time (EST). Therefore, midnight will register as 03:00.
NOTE: this page is under construction.
Individual Journal Assignment
- Store this journal entry as "username Week 3" (i.e., this is the text to place between the square brackets when you link to this page).
- Create the following set of links. (HINT: These links should all be in your personal template that you created for the Week 1 Assignment; you should then simply invoke your template on each new journal entry.)
- Link to your journal entry from your user page.
- Link back from your journal entry to your user page.
- Link to this assignment from your journal entry.
- Don't forget to add the "BIOL398-04/S15" category to the end of your wiki page.
MATLAB Skills Development
- Part I: Create a script that includes the following elements
- Define a vector u containing the elements 1,2,3,4,5,6,7,8,9,10 using the colon operation
- Define another vector v containing elements that are the square of the vector x
- Plot v versus u (make sure you know what that sentence means!!) using circles on the points that are connected with dashed lines
- Save your plot as a TIFF file
- Save your data into an excel spreadsheet using the MATLAB command xlswrite
- Part II: Use MATLAB to solve the equation ln(x) + x = 0. The following steps will help.
- Create a function that returns ln(x) + x; its first line should be
function [y] = logPlusX(x)
- Create a script that uses the MATLAB function fsolve to solve the equation. This script may be short.
- Part III: Play with the four m-files from the Thursday Jan 22 schedule box.
- Run the nutrient/colony model
- Run the chemostat model
- Save the graphical output from these two runs to JPEG files.
- Run the chemostat model a second time, but cut the dilution rate in half
- Plot both chemostat model runs on the same graph, adding a legend that allows a reader to identity both runs, and save as JPEG.
How To Submit Your Work
- Part I.
- Upload the MATLAB script and provide a link on your individual journal for Week 3.
- Upload the Excel workbook and provide a link on your individual journal for Week 3.
- Upload your graph's TIFF file and provide a link on your individual journal for Week 3.
- Part II.
- Upload your script and function files and provide a link on your individual journal for Week 3.
- Post the numerical answer you got on your individual journal for Week 3.
Part III.
- Upload three plots and provide a link on your individual journal for Week 3.
- Store your shared journal entry in the shared Class Journal Week 3 page. If this page does not exist yet, go ahead and create it (congratulations on getting in first :) )
- Link to your journal entry from your user page.
- Link back from the journal entry to your user page.
- Sign your portion of the journal with the standard wiki signature shortcut (
~~~~
). - Add the "BIOL398-04/S15" category to the end of the wiki page (if someone has not already done so).
Reflection
- What was the purpose of this assignment?
- How might you adjust the chemostat program to use two nutrients?
- How do might these equations relate to the journal club paper?
