Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: School of Biomedical Engineering
Unit Coordinator/s: Dr Kyme, Andre
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Prohibitions: BMET2960 OR AMME2960
Brief Handbook Description: BMET9960 is designed to equip you with the necessary tools to mathematically model and solve a range of canonical problems in engineering: conduction heat transfer, vibration, stress and deflection analysis, convection and stability. You will learn how to compute analytical and numerical solutions to these problems, and then apply this to relevant and interesting biomedical examples. By the end of this unit you will know how to derive analytical solutions via separation of variables, Fourier series and Fourier transforms and Laplace transforms. You will also know how to solve the same problems numerically using finite difference, finite element and finite volume approaches.

The theoretical component of the course is complemented by tutorials where you will learn how to use Matlab to implement and visualise your solutions. There is plenty of support in the early weeks of the unit to refresh your Matlab knowledge, or to learn Matlab for the first time if you've had no prior experience. Gaining a good working knowledge of Matlab to solve engineering problems and explore the solution space of these problems is one of the key benefits of this unit - it will set you up very well for future units requiring programming expertise!

There is a strong emphasis in both the lectures and tutorials on example-based learning - you will see and attempt many different examples involving a wide range of biomedical applications. Applications include electrical, mechanical, thermal and chemical mechanisms in the human body and specific examples include heat regulation, vibrations of biological systems, and analysis of physiological signals such as ECG and EEG.

This is a challenging but very rewarding unit and you'll come away feeling well-equipped with useful tools for your future engineering career. We hope you enjoy it!

The relationship between the analytical and numerical approaches is explored and also the relevance of this for real-life engineering. (1) Maths/ Science Methods and Tools (Level 3)
Assignments, tutorials and quizzes: Students apply mathematical techniques to specific biomedical problems and explore the dependencies of their solutions.
Tutorials: Students learn how to frame a problem in computer code, implement and debug their code, and visualise and present the results.
Assignments: Students practice presenting concise engineering reports.
(2) Engineering/ IT Specialisation (Level 2)
Assignments and tutorials: Students must think creatively about the solutions for the tutorials and assignments, which focus on real-life engineering problems. (3) Problem Solving and Inventiveness (Level 2)
Lectures, tutorials and assignments: Because much of the content of this unit is shared with AMME2000, students will many examples of how the same mathematical techniques can be applied across mechanical, aero and biomedical applications. (5) Interdisciplinary, Inclusiveness, Influence (Level 2)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Assignment 2: Analytical and numerical solution to the wave equation.

Assignment 3: Finite element solution to an engineering problem.

Quiz: Analytical solutions to the heat and wave equations, integrals and transforms.

Weekly pre-work: This mark is based on a short quiz, based on the pre-work for that week, and to be completed prior to the lectures that week.

Tutorial assessment: One exercise from each tutorial must be completed by 9 am Tuesday of the following week. A student completing all exercises successfully will gain 10%.

Late assignments will be penalised at a rate of 5% per day (a mark of 0 will be awarded beyond 10 days late).

All assignments must be handed in as a soft copy via Turnitin.

There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes.
Assessment Feedback: Marked assessments and feedback from lecturer/tutors.
