Consequence Forecasting for uncertain times

By Dr Sean Wilkinson

Infrastructure is so ubiquitous and reliable that most people do not realize that it is even there.  But when we do get a failure in one of our infrastructure systems, well then we really do notice.  Think about the last time there was a power cut, or you were caught in a traffic jam – or worse, you could not access social media.  It is amazing how upset most people get when they don’t have access to the services that our infrastructure usually provides – even for a short time.

Infrastructure and people

nick-tylerBy Professor Nick Tyler

We often talk about infrastructure – these days increasingly about smart infrastructure – but how often do we pause and think about what ‘infrastructure’ is for – or what ‘smart’ is? We think about roads and railways, energy, communications and water infrastructure as serving some purpose, such as moving traffic from A to B, or supplying sufficient energy to keep the lights on, but there is a more fundamental question: why do we need to do these things? Given the amount of money (that should be) invested in infrastructure, perhaps we should be asking such a fundamental question before we start proposing what should be built. Continue reading

Closed-loop supply chain decisions using game theoretic particle swarm optimization

kalpit-patneBy Mr. Kalpit Patne

Closed loop supply chain management (CLSCM) is a relatively new field in the area of supply chain management and logistics which involves all the reverse logistics activities in addition to the forward logistics, like product acquisition, remanufacturing, redistribution, disposal etc. Continue reading

A spatial mircosimulation model to forecast health needs of elderlies in 2030 for Belgium (work in progress)

Morgane DumontBy Ms. Morgane Dumont

The forecasting of the population’s health needs is a big challenge in the current society, since the proportion of elderlies within the population is continually increasing. To allow each older person to live in a good health, health services need to be adapted. The project Virtual Belgium in Health (VBIH) aims to develop a platform based on a spatial micro-simulation that will approximate the health needs of elderlies in Belgium for 2030. Continue reading

Assessing the vulnerability of hydrological infrastructure to flood damage in coastal cities

Robert OgieBy Robert Ogie

Hydrological infrastructure such as pumps, floodgates (or sluice gates), dams, embankments, and other flood barriers are invaluable assets used in coastal cities for mitigating flooding. These infrastructure components are often vulnerable to damage or failure due to the impact of floodwaters, thus exacerbating the flood hazards and causing significant loss of life and destruction to property worth billions of dollars.

Big data platform for mining user-generated content (UGC)

Jack YangBy Jie (Jack) Yang

I am currently undertaking a study which uses an innovative cloud-computing tool – developed here at SMART Infrastructure Facility – to collect, analyse, and visualise data from different social media networks in Australia, China and Korea. Specifically, it aims to investigate how different countries are using social media platforms respectively to contribute to topical conversations on culture and politics. By gathering, sorting, and displaying information from millions of data records on various topics such as films and TV dramas, this project will increase public awareness among three different countries.

Mining a System: The Use of Data Mining and System Dynamics to Explore Technology Integration

??????????????????????By Jack (Jie) Yang, Jun Ma & Sarah Howard

Technological innovation in schools has, as yet, resulted in relatively limited teacher and student engagement with new ways of learning supported through information and communication technologies (ICTs). One of the possible reasons for this is that educational research has struggled to grasp the complexity or dynamic nature of technology integration. Data mining techniques have drawn the attention of researchers from the education research area to understand some of the complexity of technology integration within a theoretical system model of technology integration. Continue reading

Tweet Semantics

Rodney ClarkeBy Associate Professor Rodney Clarke

All major approaches used to analyse tweets (statistical and machine learning) proceed from the segmentation and classification of lexical items (words). An alternative approach involving computer-based grammars is rarely used because they do not scale well to the dimensions necessary for the analysis of PetaJakarta tweet traffic. All current approaches are syntactic and asemantic. They are incapable of addressing questions concerning how citizens are actually using social media platforms during emergencies because they are incapable of explaining how language is structured for use.
