ISSNIP Visitors 2007

Prof. Hugh Durrant-Whyte – University of Sydney

Prof. Durrant-Whyte’s keynote talk at ISSNIP 2007 highlighted the importance of information state filtering and use of mutual information in autonomous mobile sensor networks. He showed that these concepts lead to robust algorithms that can solve highly complex but very practical tasks like the control of autonomous unmanned aerial as well as ground vehicles in mining. The talk related to direct work done at the University of Melbourne where numerous people are involved in scheduling and trajectory planning tasks for UAVs.

 

Prof. Lyle Noakes - The University of Western Australia

Dr. Eric Wing Ming Wong - City University of Hong Kong

The visit of Eric Wing Ming Wong, Associate Professor at the City University of Hong Kong, focussed on a project aiming to evaluate how large buffers need to be as bit-rate increases in Dense Wavelength Division Multiplexing (DWDM) networks. This is an important question because buffering in the optical domain is very difficult and costly.

In an extensive collaboration that include Eric Wing Ming Wong, Lachlan L. H. Andrew (from Caltech), Tony Cui (PhD student, University of Melbourne), and three University of Melbourne, Dept. of EEE professors: Bill Moran (ISSNIP CI), Rodney S. Tucker and Moshe Zukerman (ISSNIP CI), a model was developed that evaluates packet blocking probability for a DWDM network and we have demonstrated that very small buffers are required.

A paper entitled "Towards a Bufferless Optical Internet" co-authored by all the collaborators has been completed and submitted to OSA/IEEE Journal of Lightwave Technology. 

The ISSNIP researchers plan to extend their collaboration with Eric W. M. Wong and L. L. H. Andrew to study how best to design and dimension DWDM networks to meet required quality of service requirements at minimal cost.

 

Dr. Ron Addie - University of Southern Queensland

Associate Professor Ron Addie from the Department of Mathematics and Computing at the University of Southern Queensland, visited Prof. Moshe Zukerman from the Electrical and Electronic Department at the University of Melbourne us for one week in early December 2007.

During his visit they explored a method of evaluating the performance of the Internet including the well known long range dependence statistical characteristics of Internet traffic. In particular, these models require special methods of simulation. A suitable simulation technique was developed and preliminary experiments undertaken. Further development and validation of the simulations has been undertaken since and is expected to produce validated results soon.

 

Prof. Steve Wright - University of Wisconsin-Madison, USA

Steve Wright was Plenary Speaker at the 51st Australian Mathematical Society Conference. The September 2007 visit was supported by ISSNIP. Dr Wright delivered a plenary lecture on "Optimization: Foundations and Applications" and an address on "Optimization and Cancer Treatment" to an audience of teachers. The meeting also provided an opportunity for discussion with ISSNIP-affiliated colleagues Natashia Boland, Andrew Eberhard, and Danny Ralph on research topics, including optimization-based algorithms for machine learning and support vector machines. These are extremely active areas within ISSNIP and many opportunities for future collaborations between optimization specialists, computer scientists, and electrical engineers were identified. Such links included: compressed sensing applications, in which sparse signals can be reconstructed, using optimization techniques, from noisy observations. Compressed sensing has been the subject of intense study during the past 4-5 years from numerous viewpoints - theoretical, algorithmic, and application-related.

 

Dr. Daniel Ralph - University of Cambridge, UK

Daniel Ralph (ISSNIP CI) was a keynote speaker at the Australian Mathematical Society meeting at La Trobe University in September 2007.

The AMS talk, entitled "Nonlinear programming developments in solving Mathematical Programs with Complementarity Constraints (MPCCs)", is on a topic that provides input to utility estimation in a general economic context. It is a joint project with Eberhard and Schreider in addition to other researchers and PhD students. Additional meetings occurred during October including A/Prof. Palaniswami, and led to two initiatives that link the project to applied work that is ongoing under the umbrella of the ISSNIP, in particular on the Great Barrier Reef project. Informal discussions were also held with ISSNIP associates A.-Prof Natashia Boland (U Melbourne) and Prof Phil Howlett (U South Australia).
