This paper provides an introduction to mathematical and computational modelling with applications in science, engineering, biomedicine and industry. Topics include the translation of real- world problems into mathematical models, and the use of simulation and numerical methods to evaluate and apply the models.
(1) Introduction to estimation and mathematical modelling (2 weeks).
Scientists often carry out “back of the envelope” calculations to get a rough answer to a problem before proceeding to more exact and involved approaches. Working with a few assumptions and a number of rough measurements, we can often make some startlingly accurate predictions and estimations. We use these examples of techniques to introduce the whole notion of mathematical modelling, its weaknesses and strengths. The examples we use range from an analysis of a potential hydro scheme in Otago harbour to how we can measure the thickness of gladwrap with a school ruler.
(2) Difference equations and dynamical models (4 weeks)
Difference equations are a standard technique for describing, mathematically, how quantities change over time. We introduce the basic ideas of how to set up and describe difference equations and systems of different equations, drawing on examples from population growth, epidemiology, ecology and genetics. The emphasis is on simulation of the systems and qualitative analysis, rather on analytical solutions.
(3) Randomness and stochastic models (3 weeks)
The growing importance of simulation is one of the most important developments in model-based inference and indeed in statistical computing in general. We review relevant ideas from probability theory, with an emphasis on how to simulate random variables and processes. We demonstrate how simulation can be used to estimate quantities and integrals.
(4) Data fitting and numerical methods (2 weeks)
It can come as a surprise to students that while most mathematics papers focus exact and analytical solutions, in application most equations and integrals are evaluated numerically. We introduce and review some standard techniques for solving equations numerically, optimizing and integrating. We see how these can be used to determine model parameters from data, illustrating the ideas with applications from epidemiology and biochemistry.
(5) Uncertainty quantification (2 weeks)
In this last section we come full circle and show how simulation can be used to assess the reliability of the models and estimates. We look at how determining whether our inferences are sensitive to small changes in parameters, and introduce the thorny area of model comparison.
None, though students will be expected to do some algebraic manipulation.
There are three lectures per week.
- *David Bryant, Math and Stats, Room 514, Science III (email@example.com). David's main area of research expertise is the application and development of mathematical, computational and statistical techniques in evolutionary biology and genetics.
- *Matthew Parry, Math and Stats, Room 236, Science III (firstname.lastname@example.org). Matthew is an expert in stochastic modelling and data science.
You will have a single, one hour tutorial/lab per week, held in a computer lab. You should have been assigned tutorial times. Yes, you can change them provided that the numbers in different tutorials remains fairly balanced. Tutorials start week two.
Your final grade will combine internal assessment and the final exam. The breakdown of assessment is:
Assignments (four) 5% each
Practical test (terms req.) 5%
Midterm test 15%
Final Exam 50%
The practical test will be held during tutorial times in August. Students will be able to repeat the test until they obtain a pass and satisfy the terms requirement, though the original mark will be used for the grade. The Midterm (theory) test will be held immediately before or after semester break. The room for the test will be announced shortly. Assignments will be due at 8pm on Wednesdays and must be submitted electronically through Blackboard. Late assignments will not be accepted.
Assignments will include some exam-style questions and a written report developing a case study. The reports are to written according to a strict template discussed in class.
You have to fulfill the terms requirement in order to be allowed to sit the final exam. In this paper, to pass “terms” you must pass the practical test.
The Como101 final examination will be three hours long. You will be permitted to take calculators into the exam, but no notes or communicating devices.
There will be no required text. Lecture slides will be available on blackboard.
Your final mark F in the paper will be calculated according to this formula:
F = 0.5E + 0.5I
- E is the Exam mark
- I is the Internal mark
and all quantities are expressed as percentages.
Students must abide by the University’s Academic Integrity Policy
Academic integrity means being honest in your studying and assessments. It is the basis for ethical decision-making and behaviour in an academic context. Academic integrity is informed by the values of honesty, trust, responsibility, fairness, respect and courage.
Academic misconduct is seeking to gain for yourself, or assisting another person to gain, an academic advantage by deception or other unfair means. The most common form of academic misconduct is plagiarism.
Academic misconduct in relation to work submitted for assessment (including all course work, tests and examinations) is taken very seriously at the University of Otago.
All students have a responsibility to understand the requirements that apply to particular assessments and also to be aware of acceptable academic practice regarding the use of material prepared by others. Therefore it is important to be familiar with the rules surrounding academic misconduct at the University of Otago; they may be different from the rules in your previous place of study.
Any student involved in academic misconduct, whether intentional or arising through failure to take reasonable care, will be subject to the University’s Student Academic Misconduct Procedures which contain a range of penalties.
If you are ever in doubt concerning what may be acceptable academic practice in relation to assessment, you should clarify the situation with your lecturer before submitting the work or taking the test or examination involved.
Types of academic misconduct are as follows:
The University makes a distinction between unintentional plagiarism (Level One) and intentional plagiarism (Level Two).
- Although not intended, unintentional plagiarism is covered by the Student Academic Misconduct Procedures. It is usually due to lack of care, naivety, and/or to a lack to understanding of acceptable academic behaviour. This kind of plagiarism can be easily avoided.
- Intentional plagiarism is gaining academic advantage by copying or paraphrasing someone elses work and presenting it as your own, or helping someone else copy your work and present it as their own. It also includes self-plagiarism which is when you use your own work in a different paper or programme without indicating the source. Intentional plagiarism is treated very seriously by the University.
Unauthorised Collaboration occurs when you work with, or share work with, others on an assessment which is designed as a task for individuals and in which individual answers are required. This form does not include assessment tasks where students are required or permitted to present their results as collaborative work. Nor does it preclude collaborative effort in research or study for assignments, tests or examinations; but unless it is explicitly stated otherwise, each students answers should be in their own words. If you are not sure if collaboration is allowed, check with your lecturer..
Impersonation is getting someone else to participate in any assessment on your behalf, including having someone else sit any test or examination on your behalf.
Falsiﬁcation is to falsify the results of your research; presenting as true or accurate material that you know to be false or inaccurate.
Use of Unauthorised Materials
Unless expressly permitted, notes, books, calculators, computers or any other material and equipment are not permitted into a test or examination. Make sure you read the examination rules carefully. If you are still not sure what you are allowed to take in, check with your lecturer.
Assisting Others to Commit Academic Misconduct
This includes impersonating another student in a test or examination; writing an assignment for another student; giving answers to another student in a test or examination by any direct or indirect means; and allowing another student to copy answers in a test, examination or any other assessment.
