22/3 Exam

Homework problems

There are three home-work problems (HWP). Each assignment is typically a smaller design task or deeper exploration of some result. There exists set HWPs, but if a student wants to do a subject related or article related problem in the area discuss it with Lars during the week of the hand out of the problem.  

• HWP 1 hand out 28/1. Due 11/2 before class.
• HWP 2 hand out 11/2. Due 25/2 before class.
• HWP 3 hand out 25/1. Due 10/3 before class.

The deadline is sharp, and HWP delivered before deadline will each be graded with 0-100 points.The report is to be written using a word processor, e.g. Latex or Word or similar and organize as follows:

• Describe your analysis, using equations. Refer to the course literature or HWP information when appropriate
• Give a brief description about the numerical treatment. Comment on the figures and tables that have been inserted into the text
• Attach your numerical code.

The reports shall be emailed to me according to the deadlines above.  The grading of the assignments will be based on the degree of activity, creativity and understanding as they appear from the report. The work is an individual work. Upon request you can be requested to present part of your result.

Exercises

To each chapter there are a set of exercises giving 1-2 points depending on size, all in all there are 59 possible exercises. The exercises of the week are due on first lecture of next week. I.e. the Exercises of chapter 1-3 are due arriving to the class the 25/1 and similarly each week.

Exam

To pass the course one needs a minimum of 300 credits, from HWP and Exercises giving an E. If one has 350 or more corresponds to a D. For higher grades there an exam, depending on the number of students the exam can either be verbal or written. If it is fewer students than five that want to write the exam we make the exam verbal.
