Project: As part of the coursework in this class groups of 3-4 students will work on a project designed
in collaboration with a local bussiness or research center. You may design your own project, however you need
to get the instructor's approval for your choice before starting any work on it. Some possible choices are:
  
        -- Medical Trial Analysis -- in collaboration with Professor Jane Meza from Nebraska Medical Center, Omaha
               Project Description
               Data for the project
        -- Water Levels in Nebraska: model to predict future levels for lake McConaughy, NE -- in collaboration
              with Dr. Shuhai Zheng from the Department of Natural Resources
              Data Set 1 (Elevation/Storage/Surface Area)
              Data Set 2 (Date/Elevation/Storage)

Guidelines for grading the project:
    30 points for the mathematical content  - correct formulas and arguments, complete explanations
    15 points for esthetical aspect (use of graphs, diagrams, colors) and organization
      5 points for presenting the novelty and the significance of the work (any research that was done on the subject,
         new methods, programming skills that you learnt while working on the project, emphasize the importance of
         the work).
 
   Each project should have 3 parts. The Introduction will contain a project description, an outline of the methods
   used, and the significance of the work. In the Main Body you will include the work: a set-up of the problem,
   the hypothesis, the arguments,  and the steps taken to solve the problem. The conclusions will contain the final
   results and their interpretation.
  On a separate piece of paper, each student should summarize the work that he/she did on the project.

References:
For the material taught in class you may use as additional references besides the notes given in class,
any textbook in Linear Algebra, Differential Equations, and Statistics. You may have to find and read references
for the project that you will chose to work on during the semester.
Homework: The homework will be announced in class and posted on the web. You are encouraged to discuss
the problems with your colleagues, but you have to write your own solutions.
