ED2230 Chaos and Self-organization 6.0 credits

Course contents

Chaos and self-organization. The Gutenberg-Richter law. Fractal geometry. Mandelbrot diagrams. The 1/f distribution. The sandpile model. Applications in plasma physics.

Intended learning outcomes

Self-organization is a new way of addressing nature, economy, biology and many other aspects of man and environment. Described phenomena are typically far from static equilibrium, strongly influenced by the external environment and organize themselves through chaotic fluctuations.

Aim

Understanding for mechanisms that lead from chaotic behaviour to perfect order and harmony. Meaning of catastrophes like avalanches, earth quakes, stock market crashes and so on.

Course disposition

Hand in exercises and group-work.

Specific prerequisites

120 hp in industrial economics or electrical engineering or technical physics including documented proficiency in English B or equivalent.

Recommended prerequisites

Students with bachelor's degree, or equal, in industrial economics or electrical engineering or technical physics.

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F

Examination

• ÖVN1 - Assignments, 6.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade

After completion of the course the student shall be able to

1. explain the ubiquitous power laws emerging in different fields

2. apply power laws to Gutenberg – Richter statistics of earthquakes, starquakes and solar flares

3. describe the sand-pile paradigm and quantify the algorithm

4. show the robustness and sensitivity to initial and boundary conditions

5. explain the origin of the self-organization using the game of life as the example

6. use the self-organization paradigm in addressing density and temperature profiles in tokamaks

7. create a Java-implementation of one of the selforganizing systems

8. use the program to qualitatively hint at some of the attributes of the system

9. write a report where to describe the model and implementations

Ethical approach

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
