Scientists are delving further into artificial intelligence research, which enables computers to gather and react independently to information. Commenting in The Age last week, Professor Tim Baldwin, from the Department of Computing and Information Systems at the University of Melbourne, said that even though there is a bit of hype surrounding artificial intelligence, researchers have come a long way.
As the focus of artificial intelligence shifts towards “deep learning”, a process which mimics digital neural networks in the human brain, major companies such as Google and Facebook are racing to use this technology to improve speech and emotion recognition systems.
In November 2013, Chemical Engineering PhD candidate Joseph Richardson went to East Timor, to teach breakdancing, digital music and documentation skills to young people, as part of his 2013 Vice-Chancellor’s Engagement Award.
Joseph is completing a PhD in Chemical and Biomolecular Engineering focusing on the production of nano- and micro-scale drug delivery systems. Despite the demands of study, he has found time to apply for and receive two DreamLarge grants to make a difference to Timorese youth at risk.
“Both grants have focused on using Hip Hop to empower the youth of East Timor and to set up a sustainable art scene in the region. We had hoped to teach in the districts on this trip, but were advised to stay in Dili by our Timorese partner organisation,” Joseph said.
“Thankfully, I got to team up with a mentor and three exceptional students (Amanda Haskard, Bryan Phillips and Chris Parkinson) from the Victorian College of the Arts (VCA). This made writing the grant and planning the project significantly easier and more culturally relevant.”
Amanda assisted with the grant-writing process and worked with a group of United Nations members specifically focused on female engagement, as the project included a number of young women. As an aside, Amanda also runs SIGNAL, a youth arts space within the City of Melbourne.
Bryan taught music production of various styles on a donated portable ipad music studio. Chris taught the participants how to document their culture in an artistic way through photography, while Joseph focused on breakdancing.
Although everyone had a particular role, the project was about inter-disciplinary sharing, with an emphasis on empowering youth in culturally constructive ways.
Bryan worked with five or six local groups and helped them to produce songs from genres as diverse as punk, hip-hop, house, and culturally inspired music. He taught the principles of how to construct songs and demonstrated his extensive knowledge of software, while teaching the participants how to produce the songs.
Chris helped some of the youth learn how to film and document Timorese art, dance and music. While teaching, he also helped to organise an extensive art exhibition that later evolved into a kick-off for a photojournalism book on Timorese graffiti.
As dance coordinator, Joseph got to work with two promising groups; one was female dominated and the other male.
The two-week long project was documented by the young participants and culminated in a performance choreographed by those learning breakdancing and performed to the songs created in a mobile studio.
The group members have become local leaders and celebrities especially after the first trip. Choreography and advanced moves were finetuned, but time was dedicated to engaging with the community through impromptu performances and breakdance circles.
The trip culminated in a significant art exhibition at the partner organisation, Arte Moris, the cultural hub of the Timorese artistic community. Teaching took place at Arte Moris and they facilitated most of the youth engagement.
The art exhibition incorporated musical performances, dance performance, and a range of visual art. Hundreds of locals and internationals attended the exhibition, providing great publicity for the young performers and artists and for Arte Moris.
“This project has become truly sustainable for Dili and hopefully will move out into the districts soon,” said Joseph.
“One crew, Endure, has recently won a few national dance competitions and gained a great deal of notoriety. They want to spread their knowledge of dance to the districts and we hope to get the opportunity to facilitate this.”
“This would extend the sustainability of this project to the national level by allowing locals to teach locals,” he said.
The two DreamLarge grants have provided an exceptional opportunity for the University of Melbourne team members and for the youth of Timor. Joseph believes that the second project has solidified the concept to the young people that they can change the fate of their nation. They are actively seeking ways to do this and some are now teaching other young people in Dili, while others are taking an active role in neighborhood leadership.
Some people have received paid teaching jobs in Dili with the children of American expats. One of the more ‘troubled’ youths gave up smoking and became a youth activist. He has adapted the mentoring model and hosted a 30-strong team soccer tournament.
“It’s really more than we could have hoped for,” said Joseph.
The Melbourne School of Engineering has been involved with two successful bids for ARC Centres of Excellence, the ARC Centre of Excellence in Convergent Bio-Nano Science and Technology and the ARC Centre for Excellence for Integrative Brain Function; both will be administered by Monash University.
ARC Centre of Excellence in Convergent Bio-Nano Science and Technology
The Centre comprises a multi-disciplinary team focused on research aiming to understand and control the interface of materials with biological systems. The Centre will exploit knowledge of the bio-nano interface to design materials that transport and deliver vaccines, drugs and gene therapy agents, and to design new diagnostic agents and devices. Nanomedicines are on the cusp of revolutionizing diagnosis and therapy in many diseases. The Centre will be the focus of bio-nano research activity in Australia, uniting universities, research agencies, institutes and companies. The expected outcomes are better diagnostic and therapeutic tools designed via an enhanced understanding of the bionano-interface.
The University of Melbourne is involved right across the many research programs. Professor Frank Caruso’s group (Chemical and Biomolecular Engineering) will look at nanoscale materials engineering and biological interactions, Professor Edmund Crampin (Department of Electrical and Electronic Engineering) will examine computational approaches to model materials-biological interactions, while Professor Stephen Kent in the Department of Microbiology and Immunology will study the immunological responses from the engineered materials.
ARC Centre of Excellence for Integrative Brain Function
The Centre will be the Australian focus of the international quest to understand how the activity of brain cells mediates the way we interact with the world. We will study how electrical and biochemical activity is coordinated across brain regions, and across time, to enable adaptive behaviour. It will study three key integrative functions: attention, prediction, and decision. These functions are familiar to everyone; for example when crossing a street, your attention may be drawn to an oncoming car, your brain works to predict the car’s path, and you decide whether to continue crossing or to retreat to the kerb. These integrative functions depend on collecting accurate sensory information, and weighing this up based on experience and memory. We will probe these functions non-invasively in humans and, in parallel, through experimental studies of other mammals.
Professor Stan Skafidas (Director of the Centre for Neural Engineering) and Dr Steven Petrou, from the Department of Electrical and Electronic Engineering, will be involved in developing new nanoscale electrophysiological and biochemical sensors that will permit us to interface and measure the activity of complex neuronal networks from the cell scale up with the aim of understanding brain function.

Dr Christine Satchell from the Department of Computing and Information Systems was interviewed by The Age, discussing social news and networking site Reddit. Dr Satchell discussed how Reddit has managed to largely avoid becoming overrun with online trolls.
Dr Chris Hale from the Department of Infrastructure Engineering was featured on page 3 of The Age yesterday, calling for an overhaul of Melbourne’s rail stations, which he said are well behind world standards.
Dr Hale has recently received $156,000 in seed funding for his project examining the rejuvenation of rail stations.
In the 150th year of Engineering at the University of Melbourne, the University of Melbourne Archives has received a significant donation of papers relating to one of the School’s most distinguished graduates, AGM Michell.
Anthony George Michell (1870-1959) studied civil and mining engineering at the University, graduating with first-class honours (BCE 1895, MCE 1899). He is most renowned for his brilliant invention of the tilting pad thrust bearing, which allowed for the development of larger, faster and more powerful ships and is still the standard used in shipping today, over one hundred years later.
The Victoria Branch of the Institute of Marine Engineering, Science and Technology (IMarEST) made the recent donation in recognition of the importance of Michell’s contribution to their profession. The material was in the possession of their member Alan H Taylor OAM, a pre-eminent Australian marine engineer and the first non-British President of the international body since it was established in 1889.
The University of Melbourne Archives was selected as the place of deposit because of the existing Michell collections and because of Michell’s lasting association with the University and Melbourne. This association extends to the creation of the Michell Hydraulic Laboratory and permanent exhibition in the School of Engineering and the awarding of the Michell Prize in Engineering.
The donation consists of a box of correspondence, technical data and original blueprints of thrust and journal bearings. The blueprints are of obvious significance, but the correspondence is the first cache of correspondence from Michell that has been donated to a public archive anywhere in the world, as his papers are widely thought to have been destroyed.
The material appears to have originated from the company established by Michell and his English partner, Henry Newbigin, in Newcastle-upon-Tyne. It seems that it was created as a correspondence file maintained by the general manager, H.B Scott. Most of the correspondence is between Scott and Michell, concerning the running of the company, the development of bearings and market opportunities. There is an interesting debate about the defects of ball bearings as opposed to pad bearings; Michell obviously preferring the latter. The correspondence also contains a couple of letters to John Bogert, Michell’s US representative, and Albert Kingsbury, who had developed a US patent on thrust bearing that was invented independently and prevented Michell’s entry to the US market.
It appears that the two engineers had developed similar concepts at roughly the same time, which has inevitably caused consternation regarding the ownership of the invention. A letter to Kingsbury on November 11, 1931, notes, “As you know, I desire to make due acknowledgment, whenever there is occasion, of your early work on lubrication and the independence of our respective shares in the pioneer development of thrust bearings.”
The recent donation complements a number of existing ones that together represent the largest extant collection of Michell papers. There is a small file in the papers of Ronald East concerning the development of the AGM Michell laboratory and permanent display in the School of Engineering. There is also a collection of over 2,000 drawings of Michell’s crankless engine, created by the Crankless Engines Co. Finally, there is a collection of material donated to the Engineering School by the son of AJ Seggel, Michell’s partner in the Crankless Engines Co., which contains Michell’s 1939 Kernot Medal from the University of Melbourne and his 1942 Watts Medal from the Institute of Mechanical Engineers, as well as a couple of Michell’s viscometers.
In 1905 Michell took out his patent, “improvements in thrust and like bearings” (London, Jan-July 1905, no. 875 and Australia Sept 1905, no. 4114). The first working Michell bearing was incorporated in pumps made by Weymouths for Murray River irrigation in Cohuna. From there it spread and is now regarded as having revolutionised shipping on an international scale.
In 1985, GH Vasey wrote “Today we praise George Michell for his brilliant cerebral invention – no lucky hunch, pure science and logic – in a field that needed the break-through, but whose leaders disbelieved the answer when they saw it.” The 150th year of Engineering at Melbourne, and the donation from the Institute of Marine Engineers, is another fitting reason to celebrate the achievements of one of Australia’s greatest engineers.
