Australian–Japanese Workshop on Real and Complex Singularities

Dates & Venue: 9–13 September 2013; The University of Sydney, Australia

The Japanese–Australian Workshop on Real and Complex Singularities is an initiative towards the further advance of scientific exchange between Australian and Japanese researchers, and is made possible with the support of the University of Sydney, School of Mathematics and Statistics, and the Mathematical Sciences Institute of ANU.

The scientific programme will be based around a series of expository lectures presented by the invited speakers, each of whom is an internationally recognised expert in an area of mathematics having substantial interactions with the contemporary theory of singularities in real and complex geometry. Each invited speaker will be asked to present lectures on a topic of current interest, but in a manner which is accessible to non-experts in the field. The central aims of the workshop are:

1. to promote interaction between Australian and Japanese mathematicians, specifically in the field of singularity theory;
2. to provide an opportunity for young mathematicians in all parts of Australia to broaden their awareness of contemporary mathematics at an international level in a relaxed and relatively informal atmosphere.

CARMA ANALYSIS AND NUMBER THEORY SEMINAR

Speaker: Dr Hamish Waterer (CARMA, University of Newcastle)
Title: A Bucket Indexed Formulation for Nonpreemptive Single Machine Scheduling Problems
Time & Date: 3:00 pm EST, Tuesday 17 September 2013
Venue: Room V205, Mathematics Building, Callaghan Campus, The University of Newcastle
Also available on the Access Grid network (venue: UNewcastle).

Abstract

An exact bucket indexed (BI) mixed integer linear programming formulation for nonpreemptive single machine scheduling problems is presented that is a result of an ongoing investigation into strategies to model time in planning applications with greater efficacy. The BI model is a generalisation of the classical time indexed (TI) model to one in which at most two jobs can be processing in each time period. The planning horizon is divided into periods of equal length, but unlike the TI model, the length of a period is a parameter of the model and can be chosen to be as long as the processing time of the shortest job. The two models are equivalent if the problem data are integer and a period is of unit length, but when longer periods are used in the BI model, it can have significantly fewer variables and nonzeros than the TI model at the expense of a greater number of constraints. A computational study using weighted tardiness instances reveals the BI model significantly outperforms the TI model on instances where the mean processing time of the jobs is large and the range of processing times is small; that is, the processing times are clustered rather than dispersed.

This research is a joint work with Natashia Boland and Riley Clement.

The AMSI workshop on Infectious Disease Modelling

Dates & Venue: 25–27 September 2013; Newcastle City Hall

Organised by the mathematical biology special interest group of ANZIAM and sponsored by CARMA and AMSI, this workshop is aimed at applied mathematicians and computer scientists.

The main thrust of this workshop will be exploring the interface between important methodological areas of infectious disease modelling. In particular, two main themes will be explored:

1. The interface between model-based data analysis ("looking backwards") and model-based scenario analysis ("looking forwards"), and the ways in which we can better integrate those two endeavours to yield more informed policy recommendations.
2. The relationship between agent-based/micro-simulation and modelling, and how we can leverage results from both forms of investigation to draw stronger inferences on the systems of interest, and be more confident in the results that we derive from models.

An integral part of this workshop is a student and ECR poster competition, with allotted time for poster viewing.

Keynote speakers

• Prof. Matt Keeling (University of Warwick)
• A/Prof. Jane Heffernan (York University)
• Dr Steven Riley (Imperial College London)
• A/Prof. Alex Cook (National University of Singapore)

  How to stack oranges in three dimensions, 24 dimensions, and beyond

Abstract: How can we pack balls as tightly as possible? In other words: to squeeze as many balls as possible into a limited space, what's the best way of arranging the balls? It’s not hard to guess what the answer should be — but it’s very hard to be sure that it really is the answer! I'll tell the interesting story of this problem, going back to the astronomer Kepler, and ending almost four hundred years later with Thomas Hales. I will then talk about stacking 24-dimensional oranges: what this means, how it relates to the Voyager spacecraft, and the many things we don’t know beyond this.

• Colloquium: Friday 27 Sept, 15:00 (SA time, 15:30 EST);
  Horace Lamb Lecture Theatre, University of Adelaide.
  Dynamics and the geometry of numbers

Abstract: It was understood by Minkowski that one could prove interesting results in number theory by considering the geometry of lattices in \mathbb{R}ⁿ. (A lattice is simply a grid of points.) This technique is called the “geometry of numbers.” We now understand much more about analysis and dynamics on the space of all lattices, and this has led to a deeper understanding of classical questions. I will review some of these ideas, with emphasis on the dynamical aspects.

Public Lecture — Early-Career Lecturer, AustMS Annual Meeting

Speaker: A/Prof Sommer Gentry (US Naval Academy)
Date & Time: Monday 30 September, 19:00 EST
Venue: Eastern Avenue Auditorium, University of Sydney
Title: Faster, Safer, Healthier: Adventures in Operations Research

Abstract: While mathematical advances of all sorts have impacted our world for the better, operations research is a branch of mathematics that is expressly focused on applying advanced analytical methods to help make better decisions. Operations researchers have eased traffic jams by closing selected streets, and gotten packages to you more quickly by planning U.P.S. routes with fewer left turns. Operations researchers have shown which personal decisions are the leading causes of death, and planned maintenance schedules to minimize bridge collapses. I use operations research to get more people a kidney transplant, and to make sure liver transplants are allocated fairly to people who live in different places across the United States.

The mathematical tools of operations research, like using random numbers to simulate a range of outcomes when some data are unknown, or finding clever algorithms that shortcut the need to try every possible decision in order to find the best one, can be recycled and used to solve other practical problems. In this talk, I will describe some of my O.R. forays into far-flung fields, and tell my favorite stories about O.R.
