Executive Summary 2011: Business as Usual

The Centre for Informatics and Applied Optimisation experienced a great deal of change during 2011. The Centre moved into a newly formed super school, the School of Science, Information Technology and Engineering (SITE) with substantial budgetary constraints, and Collaborative Research Network projects commenced with CIAO playing a key role. Internally, many staff changes, procedural changes and uncertainty were borne with relative good humor – most importantly, the changes did not radically distract CIAO researchers from continuing high quality, business as usual, research in two ERA fields of research Mathematics (01) and Computer Sciences (08).

During 2011, 27 SITE staff members were active researchers in CIAO. An additional 6 were post-doctoral researchers and 9 were SITE staff members completing higher degrees. CIAO research was organised into four research groups, Mathematics and Optimisation Research Group (MAORG) led by Associate Professor Adil Baghirov, Data Mining and Informatics Research Group (DMIRG) led by Dr Peter Vamplew, Health Informatics Laboratory (HIL) led by Associate Professor Andrew Stranieri and the Internet Commerce Security Laboratory (ICSL) led by Associate Professor Paul Watters. Despite the turbulence of 2011, CIAO researchers produced 89, books, journal papers and conference papers that were published. CIAO researchers created new work in 4 grants previously won including 2 Australian Research Council grants. CIAO researchers successfully won new research grants valued at over $700,000 including an ARC Linkage grant. CIAO hosted the Ninth Australasian Data Mining Conference AusDM 2011 and successfully bid to host the 2012 Australian Mathematical Society Conference. A new alliance with the elite national research centre (NICTA) was commenced.

The strength of the Centre in 2011 was not made without an enormous effort from many. The brigade of 44 PhD and Masters by Research students underpinned all efforts. Five submitted doctoral research theses in 2011. Our research administrative officer, Elizabeth Mathushka who had worked so tirelessly over the years left in 2011. Professor John Yearwood, CIAO Director for some years took the mantle as Dean of the new school while Associate Professor David Yost ably took over the CIAO reigns. The heads of each group also worked tirelessly during 2011 helping to maintain a focus on business as usual. Emeritus Professor Sid Morris continued an active engagement and mentoring role.

Overall, 2011 may have been somewhat turbulent but many of the changes were water off a duck’s back for CIAO researchers as world class work continued in the applied mathematics, pure mathematics and information technology areas.

Pure Mathematics Grants: Alex Kruger commenced his ARC Discovery project DP110102011 "Stationarity and Regularity in Variational Analysis with Applications to Optimization" in January 2011. No other grants for pure mathematics were reported. Selected Projects Alex Kruger's research in nonlinear analysis and optimization straddles pure and applied mathematics. His particular interests include nonsmooth and variational analysis (subdifferential calculus, regularity) and nonsmooth optimization (optimality and stationarity conditions). Guillermo Pineda-Villavicencio continued his research in graph theory, particularly the degree/diameter problem and representations of quadratic forms. In particular, he has established the non-existence of certain classes of graphs which are too close to the Moore bound. Sid Morris continues to work on structure of topological groups. The primary effort during the last year was on three projects: 1. Investigate with Karl Heinrich Hofmann and Salvador Hernandez whether every infinite locally compact group has closed subgroups of all possible infinite weights and in particular whether infinite compact group has an infinite closed metric subgroup. This is answered in the affirmative and the paper has been accepted for publication in the Journal of Group Theory. 2. Investigate with Karl Heinrich Hofmann and Salvador Hernandez whether every infinite compact subgroup has a nonmeasurable subgroup. This research is ongoing with an affirmative answer proved in the major case that the compact group is not profinite. 3. Investigate with Arkady Leiderman and Saak Gabreleyan varieties of abelian topological groups which contain all coproducts. This research is ongoing with some attractive results already obtained. There was also progress towards preparing a third edition of the book "The Structure of Compact Groups" with Karl Heinrich Hofmann. Finally there was some progress on additional material for my online book "Topology Without Tears" and towards publishing a new translation in Greek. David Yost continued to research broadly in functional analysis and cognate areas, with progress on the one hand in the decomposability of polytopes and finite dimensional state spaces, and at the other extreme the relationship between the approximation property for non-separable Banach spaces, and the existence of large families of contractive projections.

Complex Systems Research Group Grants: USA Air Force Office of Scientific Research Grant FA9550-10-1-0487 $75,000 year Selected Projects: Supported by the USA AFOSR grant, Professor Gao and his students, post-doctoral fellow and co-workers have successfully applied the canonical duality theory and its associated algorithms for solving a large class of nonconvex and nonsmooth problems in global optimization and decision science. During the year of 2011, about 19 papers have been finished, 7 of them have been published since the last year, and seven papers are accepted. In addition, one book has been published by International/AMS Press, and a special issue of Journal of Global Optimization will be published. The following projects have been completed: Network Optimization and Sensor Localization Problems.

Researchers: D. Gao, N. Ruan, and P. Padarlos. One paper published and two papers submitted.

General Polynomial Minimization. Researchers: D. Gao, N. Ruan, C. Wu, D. Morales-Silva, Y. Chen, C. Li, X. Zhou One paper published, five papers are submitted.

Canonical Duality and Algorithms Researchers: D. Gao, N. Ruan, C. Wu, D. Morales-Silva, Y. Chen, C. Li, X. Zhou (U. Ballarat), H. Sherali, L.T. Watson, D. R., Easterlingand, W.I. Thacker (Virginia Tech). We have developed several deterministic methods and algorithms for solving some NP-hard integer programming problems. Our results shown that the canonical duality theory can be used for solving efficiently large scale discrete optimization problems. Several papers have been published online. Three papers are in progress.

Finite Element Method for solving nonconvex mechanics problems. Researchers: D. Gao, Q. Qin (ANU), H.A.F.A. Santos (Portugal) One paper published. One paper is in process.

Chaotic Dynamical Systems. Researchers: D. Gao, N. Ruan, and Chaojie Li. One paper has been accepted. Several papers are in process.

Computational Biology. Researchers: D. Gao, J. Zhang, and J. Yearwood. One paper published in Journal of Theoretical Biology, the top journal of the field.

Triality Theory. Researchers: D. Gao, C. Wu, D. Morales-Silva, Y. Chen. The triality theory was discovered by Professor Gao in post-buckling of a large deformed beam in 1996. This theory can be used to identify both global and local extrema, which plays a key role in nonconvex analysis, global optimization, modeling and simulation of complex systems. It was realized in 2003 that part of this theory needs certain additional conditions, which was left as an open problem. Now this open problem has been solved completely in the year of 2011. In the paper posted at http://arxiv.org/abs/1104.2970, it was shown that this triality theory holds strongly in the tri-duality form if the primal problem and its canonical dual have the same dimension; otherwise, both the canonical min-max duality and the double-max duality still hold strongly, but the double-min duality holds weakly in a symmetrical form, which reveals an intrinsic perfect duality pattern in complex systems. Therefore, a refined triality theory has been proposed. One paper will be published in this year, and a set of several papers are in the process.

Data Mining and Informatics Research Group (DMIRG) Grants: During 2011 DMIRG staff had no research grants awarded or active. Selected Projects: Reasoning Communities The Reasoning Community Project aims to design information and communication technologies together groups of geographically dispersed individuals, either synchronously or asynchronously to access information, deliberate and ultimately make informed group decisions. This research can be applied to support reasoning in groups exemplified by multi-disciplinary teams of medical experts or next generation democracies where citizens actively participate in policy decisions. Reinforcement Learning Algorithms and Applications Reinforcement learning is a subset of machine learning research, dealing with the development of computer agents which can learn to perform sequential decision-making tasks on the basis of feedback received while executing the task. This makes them applicable to problems where direct instruction by a human expert is not available.

2011 saw the continuation of ongoing work by DMIRG researchers investigating new developments in algorithms for reinforcement learning. In particular DMIRG researchers have developed world-leading expertise in the extension of reinforcement learning methods to handle problems with multiple conflicting objectives, such as balancing economic and environmental objectives. Other DMIRG research in this area includes investigating new means for incorporating expert advice into a reinforcement learning agent, and the use of reinforcement learning in various robotics applications.

Internet Commerce Security Laboratory (ICSL) Internet commerce has revolutionised the ways that businesses globally are able to (a) sell goods and services into new markets; (b) develop new and innovative global marketing campaigns at low cost; (c) reduce operational costs by moving towards open, internet-based standards for payments and other types of bulk processing; and (d) increase productivity by bringing tools and technologies ever closer to consumers and knowledge workers, who no longer need to physically visit a bank branch, retail mall or workplace. At the same time, the rise of internet commerce has bought about a range of new risks that are challenging to manage. Identity theft, scams and fraud of various kinds existed well before the internet became a major channel for commerce, but often, the enormous potential rewards for engaging in illegal activity on the internet far outweighs the risks for many cybercriminals. In direct response to the need to better understand the nature of the threat, the Internet Commerce Security Laboratory (ICSL) was setup in 2008 with the following objectives:

• to address commercially relevant security issues affecting the continued uptake of internet commerce;

• to focus on research into fraud and associated illegal activity in the internet commerce sector;

• build a state and national capacity to tackle security problems in internet commerce through highly trained ICT graduates; and

• to enhance the knowledge and tools available for the development of simple safe and secure environments to support the continued uptake of internet commerce and identity management.

Grants: The ICSL continued to receive funding from the University of Ballarat, Westpac, IBM, the Australian Federal Police and the State Government of Victoria. A/Prof Watters finalised work on ARC Linkage Project [LP0776267] “Defence Against Phishing Attacks” (P. Watters, B. Watson, A. Ng, M. Dras, S. Cassidy, S. McCombie, B. Reardon, J. Pieprzyk) awarded in 2007. Selected Projects: Fraud Detection

The ICSL aims to have very direct outcomes to reduce loss through the internet banking channel, and build confidence in the internet banking and mobile banking channels. The ICSL has recently researched and developed a number of different algorithms to assist Westpac detect fraud in the internet banking channel, by using data mining to determine profiles which cover “normal” behaviour for users versus “suspicious” behaviour for two categories: botnets and stolen credentials.

The detection of botnets used to be significantly easier than it is today. Previously, most login attempts came from a single IP address. One common strategy was to put fake credentials into phishing websites and then block any IP that attempts to use those credentials. Nowadays, botnets spread the login attempts between many different IPs, making this type of detection impossible.


However, the ICSL has developed techniques to profile botnet clients and these profiles are used to block unauthorised transactions being initiated by botnets.

Detecting stolen credentials is a bit more difficult, particularly when they are being tested by mules within Australia. Some standard techniques, such as looking for multiple different logins from the same location or an unusual state for a customer, are possible but give false positives in many cases. Again, using data mining, the ICSL has developed a system to profile customer’s normal usage and score activities which might indicate a deviation from that profile. The ICSL-developed technology is now being used in production by Westpac, and has been effective in reducing fraud and reducing the amount of manual effort required to process suspected fraud cases (including false positives). Cybercrime Profiling The profiling research project focuses on:

1. Identifying security events of interest from a large number of messages being monitored (including e-mails and websites). This is a classification task.

2. Grouping those events together to form incidents with a common basis, eg, the same attacker. This is a clustering task

3. Building a profile from the classified and clustered events to identify incidents in a way

which is actionable by law enforcement.

Several algorithms within the profiling theme have been created to fulfil these needs including: 1. Recentred Local Profiles (RLP). RLP is a method for the attribution of documents using a

training corpus (a supervised learning task). An anti-aliasing authorship program for chat-log analysis using RLP has been delivered as requested by the Australian Federal Police.

2. n-gram Unsupervised Automatic Natural Cluster Ensemble (NUANCE). NUANCE is a method for clustering documents by authorship, where the authorship of no documents is known in advance. NUANCE is applicable to a variety of written documents, including code and HTML. This allows it to be used on phishing emails and websites to determine the size and scope of the operations behind them. A phishing profiling system using NUANCE has been delivered as requested by Westpac.

RLP and NUANCE are being assessed for potential to commercialise and apply to other fields. For example, the anti-aliasing authorship attribution programme may be licensed to foreign law enforcement organisations, while the NUANCE-based anti-phishing profiling system may be useful for banks globally.

As part of our goal to build a state and national capacity to tackle security problems, we have engaged with a number of industry stakeholders and groups to address commercially relevant security issues affecting the continued uptake of internet commerce. Some examples include policy advice to a major international search company to assess the technical feasibility of various types of internet content filtering, and a series of reports undertaken in collaboration with the Australian Federation Against Copyright Theft (AFACT), to identify the proportion of P2P downloads that were infringing copyright. ICSL staff have also attended and/or presented many industry events nationally in the cybercrime area, including the closed-doors Interbank security forums, the 3rd Annual Future of Security in Banking (FST MEDIA) event in both Sydney and Melbourne, and the Identity Theft Symposium (organised by Queensland Police). ICSL staff have also engaged with IBM in several different ways, including attendance at IBM Technical Leadership Exchange, and joint sponsorship of “Twilight Technical Talks” held on the Ballarat Technology Park.

Making the Case for CAM Informatics UB Stranieri, QUT Sahama, Epworth Hospital Vaughan

As globalisation advances, many patients have increasing access to physicians practicing medicine from diverse medical modalities including Traditional Chinese Medicine (TCM), Western Medicine (WM), Homeopathy and Ayervedic Medicine (AM). Evidence is already strong that the use of complementary medicine is currently quite prevalent in Western nations (Cohen et al 2004; Ana 2001). Conversely, a growing proportion of residents in non-Western nations are accessing Western medicine and its pharmaceutical interventions.(Zaslawski 2003; Chua et al 2008).

Although the application of informatics to Allopathic medicine is well advanced very few studies explore informatics as it applies to Holistic medicine.

This project aims to explore open questions and conceptual publications that aim to identify the need and challenges for CAM informatics

CAM Informatics conference 2012 Planning commenced in 2011 for CIAO to co-host the The 3rd International Conference on Holistic Medicine ICHM 2012 with a CAMI Informatics stream is to be organised by HIL with QUT and University of Colombo.

Technologies for Empowering People for Participation in Society (TEPPS) UB Meredith,

The TEPPS programme aims to enable the lives of people the world over through the radical design of software and hardware solutions. TEPPS are designed through close target user collaboration and have the aim of empowering peoples' lives. The TEPPS programme focuses on researching, designing, implementing and evaluating simple, accessible and cost-effective enabling systems. Another focus of the TEPPS programme is to research equity in terms of health support provision and quality of life issues.

Close target user informed design and key stakeholder collaboration are key priorities for any ventures that the TEPPS programme decides to explore. Universal design is a priority in order to create appeal and to encourgae uptake for a product beyond the intended target audience. By carefully simplifying design you can maximise the user experience and enhance interaction.

Projects range in nature from immersive virtual worlds with rich interactions and three dimensional environments, through to DVD-based applications and simple web-based interfaces.


TEPPS sought to form collaborative partnerships within industry, government bodies, community organisations and academics. Examples of past and current relationships, and collaborations include Australian Speak Easy Association; The Australian McGuire Programme; and The Australian Stuttering Research Centre.

TEPPS Projects: Funded Projects: Scenari-Aid: Simulated Scenario System Stuttering effects around 1% of the population and has vast repercussions beyond the complex motor skills of speech. This equates to currently about 54,000 Victorians being directly afflicted and a ripple effect of issues spreading out to their families, friends and work colleagues. The act of stuttering can cause destructive ripple effects throughout an individual’s life including conditions such as depression and poor feelings of self worth, and can have adverse effects with regard to educational choices, careers, social relationships and health care. The cost to the community is estimated to be great as a result of the untapped potential that can occur due to some people who stutter choosing not to interact fully and fruitfully in society. The following organisations, universities and support services are using Scenari-Aid: Australian Speak Easy Association; Australian Stuttering Research Centre; Bankstown Stuttering Unit; Dr. Brenda Carey Stuttering Specialist; The Scottish Rite Childhood Language Centre (Richmond, VA, USA); Flinders University: School of Human Communication Sciences; Macquarie University Speech Clinic; McGuire Programme (Australia); Pinarc Support Services; Stuttering Research & Treatment Trust (New Zealand); Talk to Literacy; Tracy Kendal Speech-Language Therapy (New Zealand); and Voice Culture (New Zealand) Virtual Stuttering Support Centre The Virtual Stuttering Support Centre (VSSC) sits within the University of Ballarat's own island in 2nd Life (Direct link to the VSSC). The VSSC is a six story high building housing social, support and simulation options. Within the VSSC all users ware encouraged to communicate with each other using their real voices via a standard microphone and speaker/headset package. It really should be seen as a perfect and comfortable environment to communicate with fellow people who stutter.

Online dispute resolution for Electronic Health Record Disputes

UB Stranieri, Venkatranum; Deakin Bellucci, Abernathy. Within a UB-Deakin CRN project, A/Prof. Andrew Stranieri and Dr. Sita Venkatraman are investigating on the potential use of Online Dispute Resolution (ODR) and the role of Emotional Intelligence (EI) for resolving disputes related to Electronic Health Record (EHR). It involves the development of a hybrid ODR/Decision Support model to resolve disputes related to Personally Controlled Electronic Health Records (PCEHR) system that Australia has recently launched. This research project is conducted in collaboration with Deakin researchers, A/Prof. Jemal Abawajy and Dr. Emilia Bellucci. In 2011, the research team also included two SITE research students, Nial Muecke and Rebecca May, and the ODR software called ReConsider was designed, developed and tested successfully. Further investigations with several case scenarios would be considered in future. Victorian eHealth clusters and Health Privacy Commissioner consider this research to be vital as it would offer great benefits to disputants without the additional cost and time required for a litigated resolution in Australia.

Grid based processing of patient sensor data UB PhD Project: Ather Saeed, Andrew Stranieri, Richard Dazeley

Wireless sensor devices are used for monitoring patients with serious medical conditions. Communication of content-sensitive and context sensitive datasets is crucial for the survival of patients so that informed decisions can be made. The main limitation of sensor devices is that they work on a fixed threshold to notify the relevant Healthcare Professional (HP) about the seriousness of a patient’s current state. Further, these sensor devices have limited processor, memory capabilities and battery. A new grid-based information monitoring architecture is proposed to address the issues of data loss and timely dissemination of critical information to the relevant HP. The proposed approach provides an opportunity to efficiently aggregate datasets of interest by reducing network overhead and minimizing data latency. To narrow down the problem domain, in-network processing of datasets with Grid monitoring capabilities is proposed for the efficient execution of the computational, resource and data intensive tasks. Interactive wireless sensor networks do not guarantee that data gathered from the heterogeneous sources will always arrive at the sink (base) node, but the proposed aggregation technique will provide a fault tolerant solution to the timely notification of a patient’s critical state. Experimental results received are encouraging and clearly show a reduction in the network latency rate.

Incorporating values in organisations UB PhD Project Faezeh Afshar, Andrew Stranieri, John Yearwood

Values have been shown to underpin our attitudes, behaviour and motivate our decisions. According to Schwartz (1992) values do not exist in isolation but have meaning in relation to other values. The Schwartz Value Survey (SVQ) is an instrument that an individual uses to identify a ranked list of values that describes his or her value system. However, values are not solely the purview of individuals as communities and organisations have core values implicit in their culture, policies and practices. Values for a group can be determined by a minority in power, derived by algorithmically merging SVQ ranked lists of participants, or set by deliberative consensus. The elicitation of values for the group by deliberation is likely to lead to widespread acceptance of values arrived at, however enticing individuals to engage in face to face discussion about values has been found to be very difficult. We present an online deliberative communication approach for the anonymous deliberation of values and claim that the framework has the elements required for the elicitation of shared values.

Support system for the assessment of needs of cancer patients UB Stranieri, Love, Sid Kulkarni.

Grampians Integrated Cancer Services Stephen Vaughan

Regular assessment of wellness or quality of life for patients throughout a cancer journey is important so as to identify aspects of life that could lead to distress and impede recovery or acceptance. The emerging trends in assessment are to deploy validated, quality of life instruments on touchscreen computers in medical waiting rooms. However, these add to workload of health care professionals and can be impersonal for patients to use. In this article, an alternate approach is presented that involves a decision support system with natural dialogue that elicits the patient's specific context in a far finer grained manner than is possible with questionnaire based instruments. The system includes a model of heuristics that health care professionals in a locality use to make inferences regarding a patient's quality of life and avenues for referral.


HD3D Telemedicine UB Stranieri; Versi Collman, Borda, Myers; Consortium including GRHA, Dept of Psychiatry (UM), Melbourne Dental School (UM), Northern Health, Ballarat Health Services, Wimmera Health Care Group, West Wimmera Health Service, Heritage Lakes, Grampians Integrated Cancer Service.

Currently demand for quality healthcare continues to be driven particularly by the ageing population and by other disadvantaged communities in outer metropolitan, regional and rural Victoria. It is expected that by 2021, 17.2% of Victorians will be aged 65 years and over (ABS cat. No. 4102.0 Australian Social Trends, Data Cube – Population, June 2011). This increase means that many medical specialists and clinical and nursing staff will, in the future, struggle to keep up with increased workloads. This will then impact on the ability to provide greater access to quality care to the aged and disadvantaged. Access to appropriate healthcare is vital for positive health outcomes. High capacity communication links (such as the NBN) and high quality 3D and HD technology allows a very immediate and realistic experience for specialist, clinical and nursing staff for many different assessments and treatments. This means that residents in nursing homes and those in regional, remote communities can receive high-quality care without always making an expensive and stressful trip to see a specialist face-to-face. This is seen as a part of the current healthcare crisis solution. The University of Ballarat’s Centre for Informatics and Applied Optimisation (CIAO) leads a consortium of IT and health care organisations to develop proof-of-concept trials incorporating high definition and 3D telemedicine. These proof-of-concept trials will be conducted over 8 sites, involving 12 health organisations, with top clinicians, nurses and specialists and will demonstrate what can be achieved by increased (remote) access to tele-oncology, tele-psychiatry, tele-wound management and tele-dentistry in hospitals/health facilities, aged care centres and the home. The project is funded by State Government Boardband Enabled Innovation Program (BEIP) and will run from October 2011 to October 2013.

Decision support for occupational health and safety UB Stranieri; RMIT. Prof Helen Lingard, Assoc Prof Nick Blismas

Funded by an ARC Linkage 2012-2015. In some Australian jurisdictions (Western Australia, South Australia, Queensland and Victoria), specific obligations for OHS designers of buildings and structures have been established in the legislation. However, it is far from apparent that construction design professionals possess the OHS knowledge, skills and abilities they need to comply. Knowledge-based systems (KBSs) seek to replicate, by computer, the problem solving expertise of human specialists. KBSs are ideally suited to providing OHS decision support because OHS is a specialist area in which it is undesirable to learn from one’s mistakes. Two ways in which KBSs have been successfully used to aid OHS decision-making are in the provision of regulatory advice and in supporting the OHS risk management process. This paper describes a project currently underway to design, develop and rigorously evaluate a knowledge-based decision support tool to assist construction designers to manage OHS risks in the design process. The conceptual design of the decision support tool is described and an example provided to demonstrate the use of a Generic Actual Argument Model to represent design OHS knowledge.

Structured Reporting for Teledentistry UB PhD Project George Kadamupzha, Stranieri

Involves the design, development and implementation of a ripple down rule structured reporting system applied to tele-dentistry.


Data mining Cardiovascular Autonomic Neuropathy UB Huda, Stranieri; CSU Jelinek; Deakin: Aberwathy, Chowdhury

Cardiovascular autonomic neuropathy (CAN) is one of the important causes of mortality among diabetes patients. Statistics shows that more than 22% of people with type 2 diabetes mellitus suffer from CAN and which in turn leads to cardiovascular disease (heart attack, stroke). Therefore early detection of CAN could reduce the mortality. Traditional method for detection of CAN uses Ewing's algorithm where five non-invasive cardiovascular tests are used. Often for clinician, it is hard to collect these records from patients due to the test conditions. In this paper, we propose a hybrid of wrapper-filter approach for extracting novel features from the morphological data of patients ECG records and then generate easier decision rules from new features for detection of CAN. In the proposed feature selection, a hybrid of filter (Maximum Relevance, MR) and wrapper (Artificial Neural Net Input Gain Measurement Approximation ANNIGMA) approaches (MR-ANNIGMA) would be used. The combined heuristics in the hybrid MR-ANNIGMA takes the advantages of the complementary properties of the both filter and wrapper heuristics and can find significant features. The selected features set are used to generate new set of easier rules for detection of CAN. Experiments on real patient records shows that proposed method finds a smaller set of features for detection of CAN than traditional method which are clinically significant and finds an easier way for diagnosis of CAN.

Data mining for fibrillation episodes UB PhD Juhi Abuthahir ; Huda, Stranieri CSU Jelinek

The cardioversion / Defibrillator does not set in correctly in many of the people with Atrial Fibrillation (AF) suggesting that the criteria are not good enough and need to be improved. In many cases, Defibrillators detect an AF while it tries to detect Ventricular Tachycardia (VT). Therefore, it is important as to exclude false detection of AF in detection of VT anyway. Some time ECG reports shows that there is no AF but patients has AF.

Once AF happens it is hard to overcome. Therefore early detection AF is also important. Recordings from defibrillators can be used to analyse the changes in the ECG signals before a shock and after a shock for early prediction of VT/VF.

Therefore this project attempts to find better means of identifying ECG signals features and develop sequential and dynamic models that accurately identify a future AF episode and therefore lead to the accurate engagement of the defibrillator/ cardioverter.

National ICT Australia (NICTA) An agreement signed in 2011 between the University of Ballarat and National ICT Australia Limited. According to this agreement CIAO's core member Dr. Musa Mammadov, has become a member of Control and Signal Processing group in NICTA who will provide funds to the University of Ballarat for two PhD scholarships and for Dr. Mammadov's time devoted to NICTA. This agreement envisages altogether $180,000 for 4 years that will be used at the School of SITE and in particular will provide a boost to top-level research in CIAO


Collaborative Research Network Staff from across most of the research groups within CIAO were heavily involved in the preparation of UB’s successful bid for $6m in funding from the Federal Government’s Collaborative Research Network program. Since awarding of these funds CIAO researchers have also been key players in establishing collaborative partnerships with staff at Monash and Deakin universities, and in recruiting and selecting postdoctoral research fellows to work on CRN projects. The majority of projects within CRN Element 1 are lead by or involve CIAO researchers. Element 1: Regional Science and Technological Innovation This element, through applied optimisation, informatics and systems modelling researches regional manufacturing and production systems, energy sources, telehealth, technologies, and products; and will recommend commercial applications and capacity-building relevant for regional rejuvenation. Selected Projects FEA Optimisation and Visualisation of Advances Materials This project will study constitutive laws and physical behaviour for advanced materials, from organs and skin to nano surfaces, and from smart structures to multi-functioning structures. This will be achieved by modelling complicated materials with reasonable constitutive laws, studying multi-scale and large deformation phenomena of modern materials/devices, developing unified methodology/theory/algorithms and the associated finite element methods, and advanced visualisation for effective communication and analysis. Modelling, design, and simulation of these advanced materials must deal with non-convex and large scale deformation, which produce fundamental challenging problems in both theoretical analysis and scientific computations. This study will make an international significant contribution to the convex / non smooth mechanics, which is a rapidly developing, multi-disciplinary field of research embracing modern mechanics, mathematical analysis, material science, and scientific computation.

Sloan (University of Newcastle) Decision support for supply chain management This project will apply computational techniques from the fields of optimization, machine learning and constraint programming to problems of supply chain management. This project will focus on the scheduling and planning of freight transport operations.


Regional industry depends on the efficient and timely transfer, through a supply chain, of regional produce to domestic and international markets. Improvements in this freight supply chain are essential to maintain the viability and competitiveness of regional industries. The new methods of analysis and optimisation developed in this project will have broader application, to supply chains that underpin Australian manufacturing and industry. The supply chain problems themselves are large and complex, and therefore not amenable to simple methods of analysis – the more sophisticated approaches being developed and explored in this project are vital to delivering superior outcomes. Research Leader: Dr Peter Vamplew (University of Ballarat) Project Manager: Dr Peter Vamplew Research Team: Professor David Gao, Dr Peter Vamplew, Dr Ning Ruan, Dr Eldar Hajilarov, and Dr Guillermo Pineda-Villavicencio (University of Ballarat); Prof Kate Smith-Miles, Dr Davaa Battar (Monash University) Metamodelling and Optimisation of Complex Systems This project will combine Deakin University’s event simulation-based meta-modelling capability with Ballarat University’s optimisation know-how to address challenging problems in complex systems optimization and simulation, and to provide solutions to regional decision-makers. This project will develop low cost decision support tools for research communities and regional organizations. Regional industry faces challenging problems from the minimizing inventory costs to demand forecasting and adjustment, matching sales to capacity, production planning, and scheduling and environmental impact. The research challenge is in accurate estimation, time series prediction and the integration of effective optimization methods. Such problems in most real world applications are large scale and they may involve non convex objective functions with both continuous and discrete variables. In addition, they may involve dynamic components such as predicting and responding to variations in demand, or in the pricing and availability of supplies. The broad objective of this project is to develop and implement new methods which can be applied to such problems.
