SELT Survey Results

This course is intended for advanced study of the theory of nonlinear dynamics and its application. The course covers theory of bifurcations, deterministic chaos, and complex spatio-temporal behaviour in a diverse range of physical systems. The theory is developed in a systematic manner and incorporates analytical methods, qualitative and quantitative analysis, numerical calculations, and various “real-life” examples, ranging from mechanical and biological systems to semiconductor physics and optics. The course therefore has a distinct inter- and intra-disciplinary flavour, allowing the students to tie together and contextualise a number of concepts that they have learned throughout their undergraduate studies.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Effectively use a range of theoretical methods for analyzing nonlinear dynamics;
  2. Employ a combination of analytical, geometrical, and numerical approaches for studying nonlinear effects;
  3. Identify the characteristic aspects of nonlinear oscillations and synchronization phenomena;
  4. Describe complex nonlinear dynamics by employing the universal principles of nonlinear bifurcations and routes to chaos;
  5. Understand the properties of nonlinear waves and localization;
  6. Develop critical thinking and problem-solving abilities, and apply these to a diverse range of practical multi-disciplinary nonlinear problems, spanning from mechanics to optics and solid-state physics;
  7. Understand and communicate the fundamental concepts covered in the course.

Recommended Textbook:

Nonlinear dynamics and chaos: with applications to physics, biology, chemistry, and engineering / Steven H. Strogatz (2nd edition) - ANU Library e-book.

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Integrity . In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.


Please note, that where a date range is used in the Assessment Summary in relation to exams, the due date and return date for mid-semester exams indicate the approximate timeframe in which the exam will be held; the due and return date for end of semester exams indicate the approximate timeframe in which the exam will be held and the date official end of Semester results are released on ISIS. Students should consult the course wattle site and the ANU final examination timetable to confirm the date, time and venue of the exam.

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.

The ANU commits to assisting all members of our community to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to be familiar with the academic integrity principle and Academic Misconduct Rule, uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with.

The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.

Online Submission

You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records. Unless an exemption has been approved by the Associate Dean (Education) submission must be through Turnitin.

Hardcopy Submission

For some forms of assessment (hand written assignments, art works, laboratory notes, etc.) hard copy submission is appropriate when approved by the Associate Dean (Education). Hard copy submissions must utilise the Assignment Cover Sheet. Please keep a copy of tasks completed for your records.

Late Submission

  • Late submission permitted. Late submission of assessment tasks without an extension is penalised at the rate of 5% of the possible marks available per working day or part thereof. Late submission of assessment tasks is not accepted after 10 working days after the due date, or on or after the date specified in the course outline for the return of the assessment item.
  • Late submission is not accepted for Assignment 2
