Contact With CTAC During ICIAM 2003

Embedding CTAC within ICIAM has required several changes to the way in which CTAC meetings are traditionally conducted.  Because of the size of the total meeting issues in communication may arise.  Consequently, on Sunday registration at the Darling Harbour Convention Centre, there will be a CTAC representative to assist CTAC delegates by providing assistance and information.  On the other days, CTAC will have a desk in the ICIAM tea/coffee centre at the UTS campus where questions may be addressed.  There will be no formal CTAC presence at the Darling Harbour Convention Centre on those days.  The desk will close on Wednesday after the last CTAC session.

Contributed Abstracts and Timetable
It is now possible to view the contributed abstracts for CTAC2003 on the ICIAM site.

The timetable may be downloaded here.

Presentation Details

After discussions with the ICIAM organisers we have elected for a slightly different format of presentations.  Each CTAC session will consist of 4 presentations each of 30 minutes grouped in related streams where possible.  CTAC talks will be clearly identified in the printed program.

CTAC presenters are given 30 minute time slots.  Speakers are limited to 20 minutes presentation, followed by 5 minutes of questions.  At this stage the formal presentation is concluded, however, in the remaining 5 minutes allocated to movement between rooms further public discussions with the speaker is encouraged, despite the movement of delegates. 

Session chairs will be asked to rigidly enforce the 20 minute limit for presentations. To ensure that the 5 minutes allocated to questions are employed gainfully before formally thanking the speaker and then allowing additional discussion through the movement period. 

Some speakers have been known to exceed their allocated times simply to avoid questions and discussion.  Discussion and questioning are a vital part of a mathematical conference and the opportunity to partake in interaction should be encouraged.  Delegates are encouraged to ask questions of speakers as they provide a vital form of feedback to the presenter, particularly to those students presenting for the first time.

Following CTAC tradition it is anticipated that most presenters will use overhead projectors.  There are data projection facilities available in each room.   If presenters wish to use the data projection facilities they need to supply and operate their own portable PCs with the presentation in Power Point or Adobe pdf form.  There is only limited technical support available for data projection facilities.  Please note there are no video facilities, such presentations need to be on a PC.

About the CTAC Meetings

CTAC is organised by the special interest group in computational techniques and applications of ANZIAM (Australia and New Zealand Applied Mathematics), the Applied Mathematics Division of the Australian Mathematical Society. These biennial meetings are organised to provide a forum for researchers working in the areas of computational mathematics and sciences and as an interface to the wider community in scientific and technical computing.

The CTAC meetings have been taking place since about 1980, and CTAC2003 is the eleventh meeting in the series.

CTAC 2003

The Computational Techniques and Applications Conference (CTAC) is held every two years in Australia.  The Conference is organised by the Computational Mathematics Group of ANZIAM (Australian and New Zealand Applied Mathematics Division of the Australian Mathematical Society).

The meeting brings together an interdisciplinary group of local and international  people who are interested in techniques of computation and/or the application of these techniques to problems in various disciplines.  These meetings have taken place since 1980, with this coming meeting being the eleventh.  For this year CTAC 2003 will function as an embedded meeting within ICIAM 2003

To register for CTAC 2003 you must first register for ICIAM 2003. Should you traditionally attend CTAC or propose to attend regularly in the future you need to indicate this by marking the appropriate indicator on the ICIAM 2003 registration form.  Registrants for CTAC 2003 are fully registered for ICIAM 2003. There is no partial registration for the CTAC sessions only.

For 2003 the CTAC conference is an embedded meeting within the International Congress on Industrial and Applied Mathematics (ICIAM 2003)


The Australian Partnership for Advanced Computing (APAC)


The CTAC conference programme will be published in hard and electronic form as part of the ICIAM 2003 program.


CTAC is usually a very close knit and interactive conference, on this occasion it is  contained within a much larger meeting.  The CTAC organisers will attempt to preserve the traditional sense of identity as best as possible.  All CTAC talks are being conducted at the University of Technology Sydney precinct.  This is a short walk from the Convention Centre at Darling Harbour.  It was not possible to host all ICIAM presentations at the Centre and the local CTAC organisers decided that the CTAC spirit would be better preserved by being in the group that used the more familiar University facilities.  The climate in July is mild and normally dry.


Accommodation is available in many hotels in the vicinity of the Sydney Convention and Exhibition Centre. Low priced accommodation is available at several Sydney University Colleges. These are located about 3km from the conference site. Accommodation for these colleges may be booked when registering for ICIAM, through the registration system. Further details on accommodation are available on

Social function

Tuesday 8th July 6.30pm for 7.00pm 

The CTAC social function will be held as a barbeque at Wesley College, within Sydney University.  The cost of the function is included in the registration fee for all registered CTAC delegates

Traditionally all CTAC delegates have attended the social function.  We will assume this tradition is being followed.  However, if you know that you will not be attending the CTAC barbeque please e-mail indicating that you will not be attending, as this will assist with the catering!

Should you wish to bring additional persons this can be arranged through the purchase of additional tickets.  These may be collected and purchased  on Sunday Night July 6 and before midday on Monday July 7 at the registration desks. There are registration desks at both the Convention Centre and the UTS (University of Technology Sydney), the location where the CTAC sessions are held.  The registration desk at UTS will only accept cash for the tickets. 

If you plan to bring additional persons please e-mail indicating the number of additional tickets you will require so they may be set aside for you.  The cost of additional tickets is $40 (Australian). 

The venue of Wesley College is at the University of Sydney (11L on this Sydney University map).  The College is approximately 5km from the Conference Centre. Those delegates using campus accommodation are already located at Sydney University. An online map of Sydney is available here. (Enter Sydney University in the suburb or town section and NSW in the state section.

Business Meeting

The CTAC business meeting will be conducted during the lunch break on Tuesday in room UC131 at the University of Technology Sydney (UTS).  The meeting will commence at 1.10 pm, allowing time for delegates to move between the two ICIAM sites.

This is the biennial meeting and the business to be conducted includes the acceptance and discussion of reports, the election of  new office holders, the appointment of a Director for CTAC 2004 and other business arising. 

All are encouraged to attend and contribute to discussions as future directions for CTAC are set at these business meetings.

CTAC as a meeting embedded in ICIAM 2003

CTAC 2003 is held from July 7-9, as part of the longer running ICIAM 2003 which runs from July 7-11. There will be several other Australian special interest meetings embedded in ICIAM 2003. Further details are available at
Of special interest to many traditional CTAC attendees is the Mathematics in Engineering Conference.

CTAC Sessions

CTAC contributed papers will be scheduled for presentation concurrently with the ICIAM mini-sympoisa. There will be no specifically invited CTAC talks at this meeting as the ICIAM organisers have arranged a rather spectacular list of invited speakers, many of whom will be of considerable interest to CTAC attendees. 

Publication of papers

Papers submitted for CTAC will be reviewed for subsequent publication in a special issue of the Journal of the Australian Mathematical Society B Series (Electronic). 

Authors are invited to submit a electronic written copy of their full papers by Friday August 8 to   Because the next CTAC meeting is in 2004 instead of  2005, there is a great time line pressure on the editors to have the proceedings  completed in a timely manner.  The organisers apologise for the additional pressures this places on both the authors and the reviewers. 

Papers will not be accepted until after CTAC 2003 has concluded in order to enable authors to consider questions and discussions arising at their presentations.

Papers are strictly limited to 10 pages and must be prepared according the specifications available at

Please note the general instructions on that page, the link to a LaTeX template you should employ and a 63 point list of do's and don'ts. 

Because the conference proceedings are in a special edition the 8 page limitation must be followed.  Authors must ensure that their LaTeX originals can be processed under a standard LeTeX system.  papers that don't conform to the LaTeX requirements defined on the indicated address may not be published.

CTAC meetings are normally biennial, however, following agreement the next CTAC will be held in 2004.  This places considerable pressure on the Editors to process papers in a timely and efficient manner.  Extensions in time to authors cannot and will not be provided if the CTAC proceedings are to appear before CTAC 2004.

For review purposes papers must be translated by a LaTeX system and the output in pdf format submitted.  Following the review process the final version of the paper for publication will be required in LaTeX form.
