Seminar Archive - 2012

Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. A complete list of past seminars can be accessed via the left-hand menu.

Dr. James Wood - Faculty of Medicine, UNSW
For immunising infections, serological data is a valuable source of information about individual and population histories of infection. In more recent times, serological data is a marker for both...

Joseph Maher - CUNY Staten Island
We will introduce random walks, starting with random walks on the line and the plane. The study of these goes back to Polya, and they can be used as elementary models for both the stock market and...

Johann Brauchart - UNSW
A Quasi-Monte Carlo rule approximates the integral of a, say continuous, function with respect to the uniform measure using the average of function values at well-chosen nodes. For example, such...

Dr Vanessa Venturi - Head, Computational Biology Group | Centre for Vascular Research | Lowy Cancer Research Centre
T cells play an important role in the immune recognition and control of pathogens. T cell receptors expressed on the cell surface enable the recognition of pathogen peptides and the diversity of T...

Professor Peter Grabner - Graz University of Technology
The question of how to evenly distribute many points on a sphere arises naturally in the context of numerical analysis on spherical domains. Surprisingly, it is not even simple to define "evenly". We...

Professor Liqun Qi - The Hong Kong Polytechnic University
In 2005, independently, Lim and I defined eigenvalues and eigenvectors of a real tensor, and explored their practical application in determining positive definiteness of an even degree multivariate...

Petrus Potgieter - Department of Decision Sciences, University of South Africa
The Brouwer fixed-point theorem is essentially non-constructive since the counter-examples of Orevkov and Baigger imply that there is no general procedure for finding the fixed point – by...

Prof Ruth Williams - University of California, San Diego
Stochastic networks are used as models for complex processing systems involving dynamic interactions subject touncertainty. Applications arise in high-tech manufacturing, the service industry,...

Peter Donovan - UNSW
Five little-known works of Alan Turing are discussed, including the two 1941 technical reports on the use of Bayesian methods in cryptology. These were released this year by the British government.

Prof Lynne Billard - University of Georgia (USA)
Massively large data sets are routine and ubiquitous given modern computer capabilities. What is not so routine is how to analyse these data. One approach is to aggregate the data sets according to...
