| | A group
can comprise of 1-3 persons enrolled in the class. Each group will
pick a particular "mini-research" question pertinent to this course
and investigate the question using simulations and/or analysis. Each
group will present their results to class on Thursday, June 9 (10:30-12:20pm),
and will submit a short report (10-15 pages including figures
and references) via email to both Raj and Adrienne before midnight June 9.
Presentation details: You may bring a powerpoint presentation on a USB stick if you want to use the class laptop or bring your
own laptop if your presentation requires special software or uses demos.
In the latter case, you should test your laptop with the projection system a day or two before to make sure the projector recognizes your laptop.
Guidelines for writing the Project Report
Please structure your writeup as a formal research report, including:
- Introduction: Should include a statement of your question and aims.
- Background: Focused explanation of the critical ideas behind your project.
- Methods: Brief description of equations, algorithms, data. Include pseudo-code if it is helpful but more lengthy code samples, if you feel they are needed, can be put in appendices.
- Results: Describe the outcome of your study, including figures from your models, data or simulations.
- Conclusions: Summarize your results, interpret them, note any drawbacks or flaws that you discovered in your study design, suggest potential resolutions or possible followup studies.
- References.
