Course Content |
Introduction into the dynamics of nonlinear systems. Continuous and discrete dynamical systems, stability analysis, bifurcations, limit cycle, chaos and strange attractors, fractals and dimension algorithms, controlling chaos, synchronization processes, and stochastic dynamical systems. | ||||||||||||
Course Goals, Student Learning Outcomes |
This course provides an introduction into nonlinear dynamics at the
graduate level. Dynamical systems that are characterized with coupling
and feedback processes often show dynamical or spatiotemporal patterns
that need to be described at the systems level; a reductionist approach
is not suited for complex systems, since the entire system behaves
different to the sum of its part. Complex systems can be
high-dimensional but must not. A necessary requirement for complex
dynamics is nonlinear equations of motion. Students learn, *how to analyze the stability of complex systems *how nonlinear systems differ from linear systems regarding dynamical properties *how sensitivity of system dynamics is related to predictability, determinism, and control *to explore dynamical systems analytically and with computer simulations |

Homework |
Homework
will be assigned weekly and will be due by 3:00 pm on the following
Friday, unless explicitely altered at the time of assignment. Late homework will not be accepted. Finished
homework should be uploaded to "google classroom" in a single pdf-file. Solutions
will be posted in the glass case in the Physics Department hallway. in case of issues with the homework link use: ffden-2.phys.uaf.edu/wacker/CLASS/648hw.html |

Project: Paper & Presentation |
Explore nonlinear dynamics with a project that includes a computational component! For example a bifurcation analysis of a dynamical system, the calculation of fractal dimensions of certain cracks; nonlinear time series analysis of an ECG, or other biological, financial, physical measurement series; correlations between two time series (synchronization); phase space analysis and quantification. Explore a topic related to this course on your own. The project needs to be based on a published paper or text book, online sources like Wikipedia are not allowed. A list of possible topics is given here: topics. You can also choose a topic of your interest in agreement with the instructor. All topics should be discussed with the instructor at least 5 days before the topic is due. Project on track: 1) project topics [20points]: submit tentative project title and a pdf file of the main literature source (paper, text book) that you use in your project. topics are due on Feb. 16. 2) project outline [30points]:
submit a one page paper proposal that includes a) scientific
background, b) hypothesis to test, and c) scientific approach and
methods to be used. outline is due on March 2. 3) project simulation [50points]:
submit one page that describes a) computational methods used, b) a
first simulation result that demonstrates that you have a basic working
computer program towards your project [this can be done through a
figure and its description; figures don't count towards page
requirements], and c) a brief outline of the remaining computational
study to be done. project simulation is due march 16.
Project paper:
The results of your project should be turned in as a paper, like an
article in the journal "Physics Today". It should consist of 5
pages [11pt,
standard margins (not larger than 1inch) and spacing, single column), including introduction, NLD background, results and discussion, summary, and
about 5 references.
figures and references do not count towards the 5 pages. The paper
needs to be turned in as a PDF-file and as a HARD COPY. The grade is
determined from physics (60%) and style (40%) of the paper. The physics
part includes correct physics, level covered, computational results, how explained, how
introduced, understanding, terms defined. The style part includes
organization and structure, title, references given, figures
referenced, good to read, grammar. the paper is due Wednesday, April 6. Presentation:
The paper will be presented to the class in a 15 minutes talk (excluding
discussions) the week before finals; an electronic copy of the presentation needs to be turned in on the day of the presentation. The grade is determined from
clarity of presentation (50%) and content (50%). The clarity of
presentation includes board/transparency use, clarity of
writing/slides, references used, blocking board/screen, speaking
clearly and loud, speed of speach, facing class and eye contact,
dealing with questions. The content includes appropriate level, enough
details, terms introduced before used, correct physics, how explained. |

Examinations | A one-hour in-term examination and a two hour final examination will be held during the semester. In-term exams will be held in the classroom. The exams will be closed books and closed notes.
|
||||||||||||
Grading | The
maximum score for each homework will be 100 points. A solution
(homework, exam) that presents nothing more than a restatement of the
problem will receive zero credit. Credit will be given for clarity of
presentation, illegible work will not be graded. Grades
are assigned as follows: A+ (>97.5%), A (>87.5%), A- (>85%),
B+ (>82.5%), B (> 72.5%), B- (>70%), C+ (> 67.5%), C (>
57.5%), C- (> 55%), D+ (> 52.5%), D (> 42.5%), D- (> 40%),
else F. For the final grade homework, exams, etc. will be weighted as follows:

Course policies | Attendance at lectures is expected. Active class participation, questions, comments on newspaper articles on modern physics are extremely welcome in the lectures. A missed exam will receive 0 credit unless the instructor is notified by email, phone, etc before the exam starts. Make-up exams will be individually scheduled with the student. | ||||||||||||
