What's On at UWA

The University of Western Australia's Careers Fair provides excellent opportunities for students to engage, network and meet prospective employers looking to recruit students for graduate programs, vacation work, internships and voluntary positions. From first year to final year, Undergraduate to Post-Graduate, the Careers Fair is for you. Come along and meet more than 80 exhibitors and attend the 10 presentations.

We generally think of bubbles as benign and harmless and yet they can manifest the most remarkable range of physical effects. Some of those effects are the stuff of our every day experience as in the tinkling of a brook or the sounds of breaking waves at the beach. But even these mundane effects are examples of the ability of bubbles to gather, focus and radiate energy (acoustic energy in the above examples). In other contexts that focusing of energy can lead to serious technological problems as when cavitation bubbles eat great holes through ships' propeller blades or cause a serious threat to the integrity of the spillways at the Hoover Dam.

In liquid-propelled rocket engines bubbles pose a serious threat to the stability of the propulsion system and in artificial heart valves they can cause serious damage to the red-blood cells. In perhaps the most extraordinary example of energy focusing, collapsing cavitation bubbles can emit not only sound but also light with black body radiation temperatures equal to that of the sun.

But, harnessed carefully, this ability to focus energy can also be put to constructive use. Cavitation bubbles are now used in a remarkable range of surgical and medical procedures, for example to emulsify tissue (most commonly in cataract surgery or in lithotripsy procedures for the reduction of kidney and gall stones) or to manipulate the DNA in individual cells.

By creating cavitation bubbles non-invasively and thereby depositing and focussing energy non-intrusively, one can generate minute incisions or target cancer cells. This lecture will begin by ranging over some of the fundamentals of cavitation and will end with a vision of the new horizons for the amazing bubble, in the process ranging from ship's propellers to medical supertools.

PS* This seminar is free and open to the public & no RSVP required.

All Welcome

In this public lecture, Professor Roland Span, Dean, Faculty of Mechanical Engineering, Ruhr-University Bochum will highlight how models developed for oil and gas applications are deficient for many important Carbon Capture and Storage (CCS) applications. He will discuss new models for predicting the properties of CCS mixtures that have been developed by his research group.

Title: Multimarkdown and typesetting mathematics.

Abstract: Markdown has been around for around a decade or so, and is a simpler alternative to xml for producing simple easy-to-read text with powerful mark-up capability. If you don't already know what Markdown is, then you really ought to know! The genius of Markdown is that it has an almost flat learning curve, and it is ideal for people who have no programming experience. It can be easily converted to RTF or HTML and is essentially platform independent. For more advanced use, there is "Multimarkdown", and yet it is still amazingly simple and intuitive. Multimarkdown can be easily converted to HTML and LaTeX, and so it has the potential to be very useful to mathematicians. This seminar is a basic introduction to this fantastic mark-up language.

The mining industry faces a number of key challenges to continuously improve the management of mine waste landforms and mine closure in environmentally and socially acceptable ways. In addition, the development and application of new technology is rapidly changing the way we design and manage them. This seminar series focusses on highlighting and addressing how several of these new developments and technologies can be applied to designing and managing tailings storage facilities (TSFs), as well as investigating some of the key ongoing challenges.

If you're a Year 12 student (or a parent of a Year 12 student), this session will provide information about UWA's courses, admission requirements and how to achieve your study and career goals.

UWA Prospective Students Office staff will be on hand to answer your queries following the presentation.

Time and place: 3pm Friday 13 March in Weatherburn LT.

Speaker: Luke Morgan (UWA)

Title: A non-classification theorem for 2-arc-transitive graphs.

Abstract: It would be great to have a classification of 2-arc-transitive graphs! Sadly, this is probably out of reach. However, there are many results on classifications of 2-arc-transitive graphs of certain orders, valencies, girth, etc... In this talk, I'll describe a recent result of Eric Swartz, Gabriel Verret and myself where we do something slightly different. Rather than classify all the possible graphs, we show that for fixed n and k, the family of 2-arc-transitive graphs of order kp^n is finite, with p a prime, once the valency is big enough (relative to n). So, our "non-classification" shows that the most interesting 2-arc-transitive graphs are those of small valency (relative to n).

In this public lecture, Professor Hermann Nicolai, Director of the Max Planck Institute for Gravitational Physics, will review some recent ideas and approaches towards a more complete theory of quantum gravity unifying the fundamental interactions of general relativity and quantum mechanics.

March 16-19 is INVESTMENT BANK WEEK

UWA Careers Centre will be hosting firms from the Investment Bank/Finance industry during Investment Bank Week. It is not essential to be studying Finance - UWA Physics, Maths and Science graduates have found work in this industry.

These events are your opportunity to meet employers, find out about their organisations, their application processes and meet key people. Come prepared with questions and think about how you present yourself to a potential employer.

Mathematics & Statistics Colloquium

Time and date: 4pm, Thursday 19th March

Venue: Blakers Lecture Theatre

Speaker: Prof. Michael Small, The University of Western Australia.

Title: Complex Systems: From nonlinear dynamics to graphs, via time series.

Abstract: Given a deterministic dynamical system - possibly contaminated by noise - what can I say about that system by measuring the time evolution of a single state? There are standard methods to answer this question, and I will review these. I will also show that by transforming the reconstructed system into a large graph, it is possible to learn even more.

Time and place: 3pm Friday 20 March in Blakers LT.

Speaker: Frederico A. M. Ribeiro (Federal University of Minas Gerais)

Title: UCS groups and associated algebras.

Abstract: Groups having many characteristic subgroups tend to have simpler automorphism subgroups, so it might be a good idea to look into the automorphism subgroups of groups having few characteristic subgroups. While characteristically simple groups are well understood, this is not the case when "few" is greater than zero. UCS groups are groups having a unique non-obvious characteristic subgroup. When investigating one of the two classes of UCS p-groups, I, together with Csaba Schneider, showed that they could be associated bijectively with a class of algebras we called IAC (irreducible and anticommutative). We can then, by looking into properties of these algebras, gather information about the groups.

Title: Vertex-primitive digraphs having vertices with almost equal neighbourhoods.

Abstract: Apart from some very trivial examples, a vertex-primitive digraph cannot have two vertices with equal neighbourhoods. (This is an easy exercise.) The first non-trivial case is thus when a vertex-primitive digraph has two vertices with neighbourhoods differing by one. I will give a proof of the classification of such digraphs, and describe a more general result and some applications.

Title: Conway Groupoids.

Abstract: To a supersimple 2-(n,4,lambda) design (a simple design where lines intersect in at most two points), one may associate a "Conway groupoid." This is a generalization of the Mathieu groupoid associated to Conway's M_13 using a `game' played on P_3, the finite projective plane of order 3. We will discuss what is known so far about Conway groupoids. Highlights include a full classification for lambda<3, a structural characterization of the Mathieu groupoid, and a surprising connection with 3-transposition groups. We also speculate on the possibility of a full classification subject to the condition that the analogue of the set M_13 actually forms a group. If time permits, we will describe a new infinite family of completely transitive codes which were discovered along the way. The talk is intended to be accessible, with plenty of time given to motivation and context. This is joint work with Nick Gill and Neil Gillespie.
