Cooperative Research Centres (CRC) Winning major participation in 3 CRC’s is
a prestigious achievement for the School
IMCRC integrates technological and
business innovation to significantly
improve Australia’s manufacturing
competitiveness, with a high degree of
interdepend between and across all
programs and projects. IMCRC’s
objective is to help accelerate
diversification of Australian
manufacturing into ‘new
manufacturing’ opportunities and
value chains. As a small high cost
economy, Australia can no longer be
competitive where the basis of
competition is scale and unit cost.
Changes in technology and
international supply chains (exhibiting
increasing complexity and
international disaggregation), together
with new innovative business
organisation, have opened up
opportunities for competitive new
manufacturing. These changes mean
that often, being small is not a
disadvantage, with such
manufacturing typically based on
short runs, high variability, and
rapidity to market, high value and
medium to high complexity.
The IMCRC project, will benefit the
Australian manufacturing industry by
providing them with a new way of
delivering design solutions to end
clients. The project aims to develop a
set of novel Spatial Augmented
Reality (SAR) user interface tools to
allow clients to directly manipulate
designs and will be led by:

Cooperative Research
Centre (D2C CRC)
iMOVE Cooperative
Research Centre
The iMOVE CRC will be working on a
new generation of Intelligent
Transport Systems (ITS) technology.
New vehicle-to-vehicle and vehicle-to-
infrastructure connectivity will provide
a platform for the development of a
smarter and more productive
transport system in Australia and
worldwide. These next generation
products, systems and services are
based on higher levels of connectivity,
greater data processing power and
lower operating costs, which will
enhance users’ travel experiences
with richer, real-time data, and more
predictive analysis.
ACRC research within the iMOVE
CRC will focus on data access, data
integration, analytics and fusion,
standards and protocols, legacy
systems and interoperability led by:
Professor Markus Stumptner
The University of South Australia is
the national headquarters for a five
year $88 million Cooperative
Research Centre (CRC) in Big Data
(started in 2014).
The mission of the D2D CRC is to
build capability to unlock the value of
Australia's data. Specifically, the CRC
will focus on arming Industry with the
tools, techniques and workforce to
unlock the value of their data in order
to make business decisions that will
improve their competiveness and
productivity in a global economy.
Led by Dr Sanjay Mazumdar, CEO of
the Defence Systems Innovation
Centre (DSIC), the CRC will initially
focus on research and development
to address the Big Data challenges of

ACRC: DATA ANALYTICS
Analytical methods for detection of social media manipulation
Project Summary: Social media provide tools for people to communicate with each other, on topics of
interest such as travel, shopping, and current affairs. However the anonymity of the Internet means that
social media have been infiltrated by people whose aim is to manipulate the opinions of social media
users, perhaps for commercial or political gain. In this project, we will develop analytical methods and
tools to detect this manipulation. The project aims to identify 'astroturfers' who covertly post under
multiple identities and 'shill' posters who post without disclosing their financial or political interests. The
tools will include forensic linguistics methods and metadata analysis, and will be applied to different
social media types. (Suitable as PhD and Masters project)

Automatic labelling of tweets in civil unrest prediction
Project Summary: Twitter data is considered as an important open source when predicting civil
unrest events. A number of models have been built with features/patterns extracted from tweets, such
as the volume-based model and planned protest model in (Ramakrishnan et al. 2014), and the
forward-looking approach to crowd behaviour prediction in (Kallus 2014). However, labelling of tweets
still remains a challenging task due to the nature of tweets. In (Zhao et al. 2014), the authors manually
labelled 5386 tweets as civil unrest related, and 6147 as unrelated, which required a large amount of
labor force. The objective of this project is to design and implement either unsupervised or semi-
supervised approaches (Hua et al. 2013), so as to label tweets automatically. (Suitable as PhD and
Masters project)

Causal data mining methods for discovering adverse drug effects
Project Summary: Adverse effects associated with medicines are among the top causes of deaths.
Early detection of adverse effects of medicines will reduce harms to patients and cut the costs for
associated medications. However, given the large amount of drugs and other restrictions, randomised
controlled trials are not always feasible to be conducted to assess drug safety. With the availability of
the large amount of health data in electronic forms and social media discussions about medicines, it is
possible to identify signals of adverse effects and their causes early in such data, as well as to
conduct automated cohort studies using the data to validate the identified signals. This project aims at
developing innovative causal data mining methods to detect the causal signals of adverse effects of
medicines from medical/health data such as medical prescriptions, and open source social media
data. (Suitable as PhD and Masters project)

Causal predication methods for evidence based decision making
Project Summary: A causal prediction is the forecast of an outcome based on its causes. Evidence
based decision making has a long history of using causal predictions. For example, in medical
domain, researchers often conduct controlled experiments or observational studies to establish causal
relationships and evaluate the effectiveness of treatments as strong evidence for therapeutic
decisions, at population level (e.g. for developing practice guideline) or individual level (e.g. for
personalised medicine). However, such approaches are hypothesis- driven. Firstly a domain expert
presents a hypothesised causal relationship, e.g. between a drug and the recovery of a disease, then
after data has been collected from controlled experiments or observations, the hypothesis is tested on
the data. In many applications, we have an abundance of data available, but we do not know what
causal relationships are hidden in the data. So it is necessary to have data mining tools to
automatically explore the data to find causal evidence. This project aims to develop efficient data-
driven causal prediction techniques to obtain the strongest possible evidence for proper decision
making and interventions. (Suitable as PhD and Masters project)

Develop data mining methods for discrimination detection in data driven decision systems
Project Summary: While big data technologies have transformed every aspect of current society, big
data analytics potentially causes social harms in a large scale.
One type of social harms is algorithmic and analytics-enabled discriminations which have been aware
of by top policy makers of USA in a report to former President Obama [1]. The report recommends
that ``The federal government's lead civil rights and consumer protection agencies should expand
their technical expertise to be able to identify practices and outcomes facilitated by big data analytics
that have a discriminatory impact on protected classes, and develop a plan for investigating and
resolving violations of law.''
Unfortunately, very few computational methods [2, 3, 4] for detecting and preventing algorithmic
discriminations in data analytics based decisions are available. This project aims to develop effective
and efficient technologies to support regulatory organisations to detect discrimination cases and for

Developing novel data mining techniques for mining educational data
Project Summary: This project aims to develop data mining techniques for effectively identifying the
factors that influence student academic performance and building better models to predict student
learning outcomes. The increasing adoption of learning management systems, such as Moodle has
enabled education institutions to collect a large amount of data related to student online activities.
Findings from such data can assist the institutions to provide timely and effective student support and
to make interventions. Educational data mining [1] has been attracting more and more research
interests in recent years. However, due to the large volume and high complexity of the data logged by
the learning management systems, traditional data mining methods are facing new challenges to deal
with the big educational data to find out true influential factors on student performance and to build
accurate and interpretable models to predict student outcomes. This project will develop new
methods, such causal discovery approaches [2] to tackle the educational data mining challenges.

Discovery and use of Twitter network structural features for civil unrest prediction
Project Summary: Social unrest is predicable using Twitter data (Ramakrishnan et al 2014) and the
structures of the Twitter networks are strong indicators. Baltimore riots and Arab Spring share many
similarities in patterns of spread of messages in Twitter (Bohannon 2015). A recent study shows that
there are clear network structure and community changes in Twitter after the 2011 Japanese
earthquake and Tsunami (Lu and Brelsford 2014). Another recent study in PewResearchCenter
characterises six types of conversational structures in Twitters: polarized, tight crowd, Brand clusters,
Community clusters, broadcast network, and support network (Smith et al 2014). This project will
study the methods for extracting structural features in social networks for improving the prediction
accuracy of civil unrest. Some related work for characterisation of Twitter networks can be found in
(Myers 2014, Myers and Shama, 2014). (Suitable as PhD and Masters project)

Effective time series feature selection for civil unrest prediction using social media data
Project Summary: Social unrest events can be modelled by time series and are influenced by other
event series (local, neighbour cities and the major cities), posts in social media, news, and economic
circumstance, etc. The extracted information from the media forms features for building classification
models (Ramakrishnan et al 2014). Each feature is represented as a time series, and the data is a
large set of time series. The aim of the project is to select a subset of time series that are informative
for the prediction the future civil unrest events. Some feature selection work of time series can be
found in (Kim 2012; Sun et al 2012). (Suitable as PhD and Masters project)

Efficient Causal Inference in Big Data
Project Summary: Causal inference is a fundamental problem in science. The access to big data has
opened up new opportunities for inferring causal relationships from purely observational data when
experimental tests and interventions are difficult or unethical. Most of existing causal discovery
algorithms are designed for a small and single data set. Thus, big data brings great challenges on
causal inference because of its volume, the diversity of data types and the speed at which it must be
managed. The project will develop efficient and effective causal inference algorithms to deal with big
data challenges for advancing big data mining techniques, and extend those new algorithms to
discover genetic causes of cancer for improving biomedical discovery. The novel causal inference
methods developed in the project will advance data mining techniques and help human beings better
understand cause-and-effect relationships hidden in big data. By extending the research outcomes to
discover genetic causes of cancer to help biomedical researchers understand critical causes and
trends buried in big biomedical data, this will bring great potential to improve biomedical discovery for
better healthcare in Australia. (Suitable as PhD and Masters project)

Identifying cancer subtypes from multi-levelled biological data with computational methods
Project Summary: Cancer is a leading cause of death, accounting for more than 8.2 million of
deaths worldwide, or 22,000 people every day. In the past decade, personalised medicine, using
genetic information to develop cancer-specific medication, has become a strong focus for health
researchers. An important step in this personalised medicine framework is to identify cancer subtypes,
as different cancer subtypes may have different treatment therapies. Since cancer is an extremely
complex and heterogeneous disease, the personalised medicine framework relies heavily on
achievements of advanced research in system biology (Wang, 2010). System biology approaches
use knowledge in Mathematics, Statistics and Computer Science to solve the biological problems.
This project will study the computational methods for identifying cancer subtypes using multi types of
biological data. Examples of related works are in (Wang et al. 2014, Liu et al. 2014). Background in
Biology is an advantage but not a compulsory requirement. (Suitable as PhD and Masters project)

Integrated Policing: Generating queries for identity resolution
Project Summary: Identity resolution aims to find whether two records are referring to the same
entity. A lot of work has been done on this topic assuming that the databases containing the two
records to be matched are fully accessible and enabling brute force comparison of all records.
However, this full access assumption becomes impractical in some applications because a database
may be too sensitive to be accessed in any way that a user likes to take. When such a database is
accessed, the user may get only one record per query or get even only true/false answers. In this
case, what queries should be used to access the database so that an identity resolution process can
use the query output to infer identities becomes a serious problem. This project aims to develop
methods and algorithms to generate best queries to access the restricted database for identity
resolution purpose. The query generation would be on the basis of an existing index over similar
entities, e.g., the similar names. (Suitable as PhD and Masters project)

Integrated Policing: Model relationships from text data for identity resolution
Project Summary: Identity resolution aims to find whether two records are referring to the same
entity. When identity resolution is required from entities in text documents, the task becomes
complicated. One reason is that a documents often refers to many entities and properties of entities
(like names of people) that are not labelled by attributes. At the same time, the relationships among
the entities are described in the documents. For example, a document may contain the sentence
‘Alice saw that Bob drove down Stephen St at 11:00pm’. Here three names are mentioned alongside
of the time entity and the relationships between these names are described. Currently, the methods
dealing with this type of text use Natural Language Parsing tools to extract entities and then put the
entities into relational tables and the match with other relational records of a database. The shortage
of this practice is that the relationships are not used. This project aims to model the entities and the
relationships extracted in text data, and develop ways to compare the modelled entities and
relationships with records in relational databases. The model is expected to be a graph model. The
comparison will need an effective method and an efficient algorithm. (Suitable as PhD and Masters
project)

Interpretable classification and prediction of civil unrest events
Project Summary: The lack of interpretability makes many sophisticated classification/regression
models infeasible in real applications, which place great emphasis on both the accuracy and
comprehensibility of the potential models, such as medical scoring systems (Letham et al. 2015). The
goal of the project is to build interpretable prediction models with patterns, which are easy for human
reasoning and understanding. There is recent progress on Bayesian analysis (Letham et al. 2015)
and discriminative pattern-based classification (Shang et al. 2016; Lou et al. 2013). The patterns or
high-order features that are highly correlated to the target civil unrest events will be used as the input
of the building of the models. The student may compare the performance of the two major
interpretable models in the context of predicting civil unrest events, and explore a new way of
interpretable prediction model, e.g. through the combination of the two approaches. (Suitable as PhD

Investigating genetic causes of cancer through complex gene regulatory networks
Project Summary: This project will study the computational methods for identifying the genetic
causes of cancer through gene regulatory networks containing multiple gene regulators. Gene
regulatory networks play an important role in every process of life, and understanding the dynamics of
these networks helps reveal the mechanisms of diseases. There have been tremendous works on
inferring gene regulatory networks. However, most of the works consider the networks with only one
type of gene regulator, such as transcription factors (Imam et al., 2015) or microRNAs (Le, 2013), thus
only help reveal part of the whole regulatory network picture. This project aims to develop methods to
construct gene regulatory networks that contain multiple types of gene regulators and methods to
isolate sub-networks that are altered between normal and cancer patients. Examples of related works
are in (Le et al. 2013, Ping et al. 2015). Background in Biology is an advantage but not a compulsory
requirement. (Suitable as PhD and Masters project)

Prediction of civil unrest events with news and other data sources
Project Summary: Tweets have played an important role in the prediction of civil unrest events, such
as protests, and may provide insights into the root causes of the events. However, online news feeds,
blogs and other sources e.g. economic time series and GDELT data, are also useful in the forecasting
of these events (Ramakrishnan et al. 2014). The informative patterns discovered from the news
sources, e.g. interactive patterns (Ning et al.2015) and precursor patterns (Ning eg al. 2016), can be
utilised in enhancement of existing predictive models that majorly rely on twitter data. (Suitable as

example, brains have evolved ways to (i) acquire information (sensing), (ii) communicate between
brain regions (information transmission) and (iii) form and recall memories (information storage).
Improved knowledge about these processes is essential for understanding how our brains "compute."
The goal of this project is to use insights from computational neuroscience to design bio-inspired

Business Process Management for the Internet of Things
Project Summary: Within the last few years, business process management has evolved from the
abstract handling of software applications involving users in front of screens that are separated from
real world events to the provision of dynamic, interoperating services that are directly linked to each
other in vast, planet-spanning process networks. In addition, emerging network-enabled smart device
standards have led to the so-called “Internet of Things” (IoT) which allows software systems to
remotely access and control devices. This has become a priority research topic in the EU, US, and
Asia and is heralded as “the next technology revolution” in a February 2013 special issue of IEEE
Computer, leading to the incorporation of IoT technology into Web applications has led to the Web of
Things (WoT). This has triggered the call for business process modelling techniques to catch up.
Assumptions that have shaped much for business process management for decades, no longer hold
in the new, distributed, real world connected environment: the assumption of a perfect world (i.e.,
events happen as they are planned), e.g., an airplane arrives exactly at the time for which its
scheduled), and the assumption of a perfect system (events become immediately known when they
occur). A fundamental property of the new generation of business processes is therefore that they
need to be time aware. An event has to be analysed not just in terms of what immediate action it
requires in response, but how the event and that action are going to affect and possibly interfere with
steps and expected events already planned for in the future. Potential key topics to be explored
include:
A declarative method to specify bitemporal business rules instead of traditional automata net
representations
A business rule language for formal characterisation of the different time-aware event processing
situations
Descriptions of how to react to events or constraint violations (e.g., pro-, or retro-actively), and for
linking these to business processes. occurrence time)

Co-Evolution of Linked Lexical Resources
Project Summary: In this era of Big Data, Natural Language Understanding (NLU) applications must
link to, query, and integrate knowledge from a variety of internal and external sources (e.g.,
knowledge graphs, ontologies, and domain models) to arrive at the understanding of a piece of text. In
our work with the Defence Science and Technology Group, for example, reading text that describes
the behaviour of entities in combat simulations requires the integration of models of actions that can
be performed (e.g., move and attack), while the entity types themselves (e.g., soldiers and tanks) are
defined in a separate ontology and individual entities may be stored in yet another knowledgebase.
The NLU application must be able to connect elements of the text to the entity types, entities, and
behaviours maintained in the different knowledge-sources; this is done through a common lexical
layer linking words (morphology), syntax, and semantics. This layer provides a common ground for
integrating knowledge from different sources through language use and is a key component of
advanced Natural Language Understanding techniques. However, the lexical layer requires extensive
management to ensure consistency between the three aspects. For example, the lexicon itself may be
updated to incorporate new terminology, synonyms, etc., or the knowledgebase constituting the
semantics of the lexical entries may be revised such that the lexical entries need to reflect the change.
Modifying the syntactic rules or semantic elements of a knowledgebase may lead to the lexicon being
out-of-date, resulting in incorrect analyses of text.
This project will investigate means of (semi-)automatically updating a shared lexicon as the result of
changes to different knowledge-sources in an NLU application. A common framework for ontology and
model adaptation should be developed along with techniques of analysing these adaptation models to
propagate changes in knowledge-sources to the lexical entries referencing them. The final result will
include a prototype implementation integrated with the NLU framework being developed within the
Knowledge and Software Engineering Laboratory. (Suitable as PhD Project)

Comparative Evaluation of Natural Language Parsers
Project Summary: Recently, Google opened-sourced their Natural Language Parser and many
groups promoted or released their own in response, providing a slew of state-of-the-art parsers for
academics and organisations to use in their work. At the same time, there are many commonly used
parsers, such as the Stanford Parser, that are widely considered to provide good results. However,
there is no high-quality, academically rigorous, and comparable evaluation of these parsers: old or
new. This project will produce a comparative evaluation of the currently available Natural Language
Parsers, including both older parsers and those newly released. The project includes the design and
execution of a systematic evaluation performed on common test corpora and will form the basis for the
comparison of the Natural Language Understanding engine being developed within the Knowledge
and Software Engineering Laboratory. (Suitable for PhD, Masters, and Vacation Scholarship)

Configuration of Software Product Lines
Project Summary: In many markets today, customers no longer consider customization as special:
they expect it. This expectation applies both to simple goods like t-shirts and to more sophisticated
products composed of heterogeneous hardware, software and services. Yet, the complexity in
engineering and manufacturing of deeply configurable products varies significantly. Numerous
sectors, such as automotive, semiconductors, and cloud services, lack tools and methods to keep
their hardware and software configurations consistent during configuration and evolution. Ad hoc
solutions frequently patch isolated problems, but fail to effectively improve overall key performance
indicators such as availability, reliability and time-to-market. Integrated solutions to align software,
hardware and service configuration are missing. Research in configuration is currently carried out in
two main communities: (hardware) product configuration and software configuration. Despite the
significant overlap in research interests, they have evolved mainly in isolation. Yet, similar challenges
and solutions have emerged in both communities.
The goal of this project is to examine the modelling methods used for product configuration (a well-
established industrial application area) and examine what benefits they can provide for Software
Product Line Engineering. (Suitable as PhD project)

Evolving Knowledge Bases automatically through Natural Language Understanding
Project Summary: Over the last ten years, a number of projects such as DIRT, NELL (the
NeverEnding Language Learner), BKB and others [1,2,3,4] have been started with the goal of learning
the content of large knowledge bases from text documents. However, most of these systems study
only the learning process in general. To make such systems relevant in practice, they must produce
useful knowledge for particular applications and must be able to consider the relevance of prior
knowledge when reading new text. This project will study the question of how additional knowledge
can be learned from text and merged with an existing knowledge base, resulting in a process that can

Hybrid Approaches to Natural Language Understanding: Integrating (Deep) Machine Learning with Knowledge
Project Summary: Natural Language Understanding (NLU), the ability for computers to comprehend
language to the same degree as a person so that they can perform actions and respond to complex
queries, is an ongoing challenge. For the last two decades, the focus of Natural Language Processing
has been on using Machine Learning techniques to train models for specific tasks, for example, Part-
of-Speech tagging, Syntactic Parsing, Sentiment Analysis, and Named-Entity Recognition. Moreover,
the recent trend of Deep Learning (i.e., the training of layered neural networks) is being applied to
NLP tasks to improve performance over traditional Machine Learning techniques.
While such approaches have been quite successful in obtaining usable results in many applications,
they have their limitations and, hence, cannot realise Natural Language Understanding on their own.
Chief among the limitations of Machine Learning methods is their inability to make use of existing
knowledge resources such as lexical resources (WordNet, VerbNet), ontologies, knowledge-graphs,
domain models, etc. These knowledge resources provide the link between human and computer
understanding; therefore, being able to incorporate them is a necessity to achieve NLU.
In contrast, non-Machine Learning approaches to NLP (i.e., symbolic, rule, or knowledge-based
approaches) can readily incorporate various knowledge resources. This allows them to perform NLU
within a restricted application domain or context; however, they lack the ability to generalise across
the large amount of data available in today's world. Instead new rules must be added manually, new
Updated 19/06/2017 21 | P a g e
knowledge-sources must be manually integrated, and large data sources may lead to inefficiencies in
processing text, if they can be incorporated at all. Therefore, to realise general NLU capability, the two
approaches must be combined.
This project aims to develop a hybrid approach to Natural Language Understanding that integrates
Machine Learning and Deep Learning with Knowledge-based approaches. It will investigate which
aspects of Natural Language Understanding can make best use of Machine Learning and Knowledge-
based components and integrate them in a prototype NLU system being developed in the Knowledge
and Software Engineering Laboratory. (Suitable as PhD Project)

Inferring Semantic Relations from Word Co-occurrence Vectors
Project Summary: A common technique in Natural Language Processing, popularised by Google’s
word2vec, is to analyse a corpus of text to produce co-occurrence vectors for each word (basically the
vectors contain one dimension per word pair), which enables us to determine the similarity between
two words. Such vector models, or distributional semantics, demonstrates some neat properties: for
example, subtracting the vector for 'man' from the vector for 'king' and adding the vector for 'woman'
results in a vector very close to that of 'queen'. However, such models are limited, finding most use in
indexing and information retrieval (such as Google's search engine), tend to focus on nouns, and are
not truly semantic. For example, two word vectors may be close together, not because they are similar
concepts, but because they are strongly related through some (unknown) relationship. These
relationships are often identifiable by the verbs and prepositions used between them. This project
aims to be a starting point for inferring semantic relations between word co-occurrence vectors by
incorporating the co-occurrence information of prepositions and verbs. The candidate will develop an
initial prototype that will identify basic semantic relations (such as parthood, and more general/more
specific terms) from key prepositions as well as a small set of domain specific relations of interest.

Knowledge management in genomics
Project Summary: Genomics (and indeed other “omix”es) are generating big amounts of data.
These can be classified into essentially 3 categories:
1. Research data
2. Clinical data
3. Reference data
At this stage, lots of effort is to build large and high quality databases capturing reference data on
gene variants, as this is a condition sine qua non for clinical evaluation of medical genetic testing
results.
There are several significant problems with such databases:
1. Assessment of pathogenicity and maintaining this assessment current (i.e. there should be a
regular review of pathogenicity assessment at least for variants deemed pathogenic) – this is the
problem with curation (as described later), but serious preparation can be done automatically
(e.g. by regularly scanning other databases, literature and in future possibly Electronic Health
Records) to detect any patterns indicating the specific variant requires (human) review.
2. Assembling and management other knowledge (from external sources?) on each variant - at
least the pathogenic ones (integration of pieces of knowledge opens questions on how to
capture/represent/resolve possible contradictions in evidence/opinion)
3. Phenotype link to the variant (I assume electronic health records should be a possible source for
this information – PCEHR nation-wide – and EPAS in South Australia might be a good place to
start experimenting).
4. Curation of the database – the load on curators is growing rapidly, so it cannot be a voluntary
commitment any more (as it used to be in the past). However, the practice is lagging behind and
such position (paid enough to attract senior experienced person) is not easy to establish. Hence
the idea offers itself to look at “crowdsourcing” – i.e. whether the curation task can be (with
serious support of IT) distributed amongst members of the community.
To support such work we have a good working relationship with SA Pathology (experts in genetics
and genetic testing) and Human Variome Project (world-wide initiative collecting data on human
variome). (Suitable as PhD project)

Natural Language Understanding for Automated Understanding of Software Requirements
Project Summary: Automated construction of software is a long-held dream of Computer Scientists
and Software Engineers. With the advent of ‘Model driven engineering’, it has moved closer to reality
as systems need no longer be developed in low level code but can be specified in terms of diagrams
of behaviour specified in languages such as UML. This project will build on earlier work to create a
system that can understand natural language text describing a particular application domain and
converts it into diagrams that can be executed. (Suitable as PhD project)

Ontology-based Information Ecosystems
Project Summary: Flexible data integration has been an important IT research goal for decades.
About ten years ago, a significant step was taken with the introduction of declarative methods (e.g.,
Clio). Since this work, mostly based on classic dependency analysis, extensions have been developed
that express more powerful semantic relationships. However, much of this work has remained focused
at the relational database (i.e., relatively low) level, and many of the extensions revert to specific
algorithms and function specifications. At the same time, models have evolved to incorporate more
powerful semantics (object or ontology-based methods). Work in this area will focus on combining
separate but currently unrelated efforts for a coordinated approach to engineering interoperability.
Use of major existing upper ontologies (e.g., DOLCE)
Incorporation of new modelling concepts such as role relationships
Incorporation of engineering ontologies (e.g., the NASA measurement ontology)
Testing using current activities related to multiple engineering standards ranging from air traffic
management over health to the oil and gas industry.

Patient journey/clinical events analysis
Project Summary: Analysis of event sequences along the path of diagnosing and treating a patient
can establish an important basis for performance (in terms of quality of care, safety of care and cost of
care) management in health care. The research required in this area spans from data mining (path-
mining, workflow mining), through to models of the patient journey and assessing the clinical/fiscal
outcomes across such models. Major challenges in this area are:
Clinical data extraction and preparation for analysis (issues such as confidentiality of the data;
reconciliation of data formats, data schemas and diverse ontologies - I expect use of UMLS
metathesaurus and other ontologies to be utilized to reconcile data from different sources; data
linkage)
Finding effective approaches to handle very rich and diverse information (data in health is seldom
complete or consistent) – methods developed for data analytics in business may not be valid in
this situation and re-validation of such algorithms may be required

Processes and workflows in clinical genomics
Project Summary: Genetic testing is a highly dynamic area of research spanning several groups of
specialists: clinicians, clinical geneticists, medical scientists, laboratories, and bioinformaticians (to
name the main ones). Members of these groups use different terminologies, may have different
objectives and come from different professional cultures.
Clinicians come from medical background (with limited depth of molecular biology knowledge) and
their main objective is to use genetic testing for better diagnosis and treatment of a given cohort of
(cancer) patients. Main issues for this group are: when the genetic testing is indicated, and how to
interpret the results. This is in stark contrast with e.g. bioinformaticians, who come from mathematical
and biology background (with very little clinical basis and exposure). Their objective is to process
massive data produced by genetic testing (such as exom sequencing) to generate a validated result.
Incorporation of genetic testing into clinical practice represents a challenge:
How we can design a set of processes which would allow integration of activities of such a
diverse group of specialists?
How we have to reconcile the differences in terminology each group of specialists is using?
What information is needed to support processes (and decision-making) at a given group of
specialists?
And how we have to design the process so that they are robust enough to cope with frequent
changes and editing (NB: all layers of genetic testing are rapidly evolving) without creation of
internal inconsistencies and contradictions?
The proposed research is to explore the application of process mining (to learn what processes are
currently used) and dynamic process modelling and integration (at semantic level – this includes
integration of ontologies as well) to design a federated, hierarchical model describing activities from
test ordering through genetic counselling, laboratory analysis, result generation, validation and
interpretation, back to clinical interpretation and use. The research will build on knowledge and tools
developed in the Semantic Systems Group. (Suitable as PhD project)

Semantic Interoperability for Big Data
Project Summary: Big Data is the “new oil” – the substance that is expected to drive the information
economy of tomorrow. Big Data applications and projects are everywhere and companies prepare for
the future where they cannot survive without the information gleaned from a variety of data sources. It
is this variety (the third of the three ‘V’s associated with Big Data: volume, velocity, and variety) that
Variety refers to the need to deal with many different data sources and data formats. This project will
examine the use of semantics (i.e., background knowledge about the data) for the effective
combination of different data sources that is a prerequisite for data mining. (Suitable as PhD project)
The work is aligned with the $88 Million Data to Decision Collaborative Research Centre (D2D CRC).

Unstructured Information Management Implementation
Project Summary: Modern text analysis applications require many different tools (existing and novel)
to work together across multiple platforms, programming languages, and architectures. These tools
must work in parallel or sequential pipelines that can be configured and customised by the application
developer. Therefore, standardised execution architectures, such as the UIMA (Unstructured
Information Management Architecture) standard released by OASIS, are a necessity for ensuring the
interoperability and consistent execution of different tools combined in an application. To this end, we
are looking for a student to develop a standards compliant implementation of UIMA in the Smalltalk
programming language and environment, along with compatible implementations of core language
processing tasks (e.g. tokenisation and sentence splitting). If time permits, the student would also
develop adapters, using the Smalltalk-Java Bridge ‘JNIPort’, to the Java implementation, Apache
UIMA, which is not 100% UIMA compliant. (Suitable for Vacation Scholarship)

Collaborative Web search (social search)
Project Summary: Research has shown that people intend to collaborate in various situations.
Nowadays people would like to collaborate through the Web while searching for information. For
example, they often desire to collaborate on search tasks. It is argued that introducing support for
collaboration and communication into information retrieval systems would help users to find
information more effectively. Collaborative information retrieval (CIR) deals with collaboration in
searching for information. The sociality trait of information search has been prominent under Web 2.0.
As an emerging online information search approach, social search not only challenges traditional
theories of information searching but influences people's behaviour as they search information online.
This project explores the characteristics of the collaboration between searchers, and among
searchers, platforms (e.g. social media) and resources available. (Suitable as PhD and Masters

Digital Forensics (including Cloud and Mobile Forensics)
Project Summary: Digital forensics (also known as forensic computing, computational forensics and
computer forensics) is a discipline that is concerned with the acquisition and analysis of digital
evidence. The use of digital forensics can be applied to any crime that involves a digital device
capable of storing electronic/digital information (e.g. in murder investigations where computers, mobile
devices and digital cameras were used). Given the constantly increasing use of ICT in everyday life,
digital evidence is increasingly being used in the courts in Australia and overseas. To reduce the risk
of digital (forensic) evidence being called into question in judicial proceedings, it is important to have a
rigorous methodology and set of procedures for conducting forensic investigations and examinations.
There is a range of digital forensic projects available across a range of different disciplinary bases.
Examples include:
Cloud forensics
Mobile forensics
Hard disk forensics, particularly Solid State Drives (SSDs) forensics
Digital forensic and incident response standards

Information and Communications Technology Leadership
Project Summary: In the turbulent, hypercompetitive business world, the impact of Information and
Communications Technology (ICT) projects on organisational activities is immense; it constantly
modifies the strategies of organisations. IT executives/Chief Information Officers (CIOs) are standing
at the center of these changes. Their role and responsibilities have changed beyond the traditional
technical service role and have grown significantly in importance. In modern day organisations much
more is expected as the role is transformed to that of a valuable business leader. This research area
investigates management and leadership aspects related to ICT executives, especially female ICT
leaders, with a specific focus on the role and responsibilities of the CIO, the challenges they face and
the essential capabilities required of them to bridge the business-IT gap in modern organisations.

Online multitasking (Mobile multitasking)
Project Summary: In the daily life, humans are naturally multitasking beings, who are often either
handing multiple tasks sequentially or in parallel, or executing one task across multiple working
sessions. These phenomena have also been recently observed on the Web environment. Multitasking
is viewed to be important user behaviour in Web/online sessions. Performing multiple tasks (related or
unrelated) and multi-session tasks are two common patterns of multitasking on the Web. In the first
pattern, Web users execute several tasks, related or unrelated, simultaneously and switch between
them; while in the second pattern, users execute a single task spanning multiple online sessions.
There has been a large body of research reporting on the second pattern, including the features and
approaches of multi-session tasks and the corresponding Web browser tools support such as
revisitation functionality and resumption support. However, little research has examined the first
pattern multitasking behaviour in Web search. This project investigates how Web users manage
multiple tasks/topics concurrently and how to present them running in parallel in a browser in such a
way as to make sense to users. Online multitasking on the mobile platform could be an interesting
focus. (Suitable as PhD and Masters project)

A New Projector Based Augmented Reality Precise CAD-Like Manipulations
Project Summary: Projector-based augmented reality is the projection of virtual information directly
onto and registered to physical objects. Users are able to view this information unencumbered by
technology, such head mounted displays or handheld devices, and they are to interact with physical
object and virtual information simultaneously. Interestingly that much of the physical hardware
(computers, projectors, cameras, and networks) requires existing technologies found in current office
workplaces today. The basic software infrastructure to correctly register the virtual information onto
the physical objects is currently operational. The research investigation into the user interface
techniques is still required to make projector-based augmented reality a useful tool. In particular, there
are a number of problems for a user performing precise manipulation for CAD-like operations.
The project will demonstrate the effectiveness of the user interface methodology by showing its ability
to support industrial activities such as: product design, training for manufacturing, in-situ information
presentation for assembly, layout for confined command and control centres, and home
entertainment. The current development of information for these is with traditional CAD applications.
The techniques developed under this proposal will allow users to interact and perform effective tasks
in a completely new fashion with computers, such as interact with simulated buttons, precise
placement of details on a physical object, presentation of animated instructions on a moving assembly
line, or react to the placement of a user’s hand on the physical object. Currently the best options are
the use of a traditional mouse and simple 3D pointing.
Research question posed by this investigation is as follows: “What are an effective precise user
interface interaction techniques to support tasks in projector-based augmented reality?”
This investigation is critical as there is not an appropriate user interface methodology for projector-
based augmented reality. The current state of the art projector-based augmented reality is simple
freehand drawing and painting, with all the precise manipulation performed with 3D CAD applications.

Augmented Reality Intelligent Tutoring Systems
Project Summary: The research aims to develop a platform for building Intelligent Training Systems
(ITS) using Augmented Reality (AR) for improving training on spatial tasks (eg machine maintenance,
object assembly, etc). There has been existing research that shows that constraint based ITS can
significantly help with improving training, and similarly AR has been used to create simple procedural
training systems. However there has been little research that has tried to combine the two fields
together to create Intelligent AR training systems, thus this research will creating a new approach for
intelligent training systems.
The overall research aim is to explore if Augmented Reality (AR) and be combined with Intelligent
Training System (ITS) software to provide a significantly improved training experience on real world
spatial tasks (eg assembly, maintenance, etc) than traditional tools (eg paper manuals, video clips,
etc). We will develop a prototype system that will allow a user wearing an AR head mounted display
(or using a desktop/handheld system) to look at real world objects and see virtual training cues

superimposed over them to help him or her learn how to perform a task in their natural work setting
(eg how to disassemble a real engine). This aim will be achieved through research conducted in four
related areas: (1) Fundamental tracking, interaction, and AR interface techniques, (2) ITS system
development and tools for spatial representation, (3) System integration and demonstration
development, (4) Evaluation and user testing. Underlying all of this work is background research in
each of the areas to ensure that we are using the most recent research approaches and that it is novel
compared to existing methods. (Suitable as PhD project)

Augmented Reality Teleconferencing
Project Summary: The goal of this project is to explore how Augmented Reality technology can be
used to enhance remote collaboration and teleconferencing, particularly for remote expert assistance
in industry. Augmented Reality (AR) is technology that allows virtual images to be overlaid on the real
world. Currently, audio and video conferencing tools can provide remote technical assistance,
however software such as Skype is typically designed for supporting face-to-face communication and
not task space collaboration, where the goal is showing the user’s workspace. In complex repair tasks
is it more important to see what the user is trying to do, rather than show their face.
Previous research has shown that using a head mounted display with a camera attached can allow a
remote expert to see what a worker is doing and provide effective support. However, there are
limitations with traditional video conferencing when it is used to support task space conferencing, such
as the remote person not being able to annotate the local user’s view, limited support for gesture
input, or being difficult for the remote user to see separate from where the local user is looking. Using
AR can overcome some of these limitations by directly annotating the workers view with virtual cues.
Earlier research has explored various aspects of using AR to improve remote collaboration. It has
shown that sharing video views of the real world, providing remote virtual pointing, using spatial audio,
and shared 3D models overlaid on real objects can all aid remote collaboration. In this project we want
to continue this research, and in particular exploring how AR can be combined with depth sensing
technologies to support very nature gesture collaboration, and the capture and sharing of the users’
environment. (Suitable as PhD project)

Deep neural networks for human emotion recognition
Project Summary: Newly developed "deep learning" methods have reignited the field of neural
networks in the last few years. For example, Google DeepMind recently announced the first
computer program that plays the game of Go at human expert level, and this relied on deep learning.
The aim of this project is to design software that learns to robustly recognise human emotions, by
making use of multiple types of sensor data, such as video, still images, and biometrics. It is expected
that the main algorithm to be implemented will be a deep convolutional neural network. It will be based
on the earlier work of Yu and Zhang [1] who have been able to get emotion recognition rates of up to
85% with a neural network technique.
The context of use will be explore if emotional recognition code can be developed that can run in near
real time on live camera video and so provide feedback on user emotion while operating a computer
interface. For example, using the video feel from a laptop camera to monitor the emotions of a person
in front of it. (Suitable for Vacation Scholarship)

Deformable User Interfaces
Project Summary: Advancing the science of Deformable Surfaces by inventing new smart materials
that can not only capture their changing form through input but can also recognise properties of the
objects they touch such as sharp, dull, curved and planar characteristics. Deformable Surfaces have
great potential to significantly change the way humans interact with computing systems - just as touch
screens have revolutionised the mobile phone and tablet computing fields. Materials and electronics
are beginning to support flexible and stretchable devices, this research will model deformable surface
properties for future applied uses. As soft deformable materials such as foam, silicon rubber and
liquids are enhanced with sensors, a host of novel devices and interaction techniques will be made
possible. This project will investigate the use of smart materials including new physical prototypes and
actuation technologies. (Suitable as PhD project)

Disaggregation of Wearable Computation Devices
Project Summary: This project will investigate the disaggregation of wearable computation devices
over different portions of the user’s body. The current trend of mobile and wearable devices is for
them to be self-contained with all the required functionality. Self-contained devices have the
advantage of being able to operate autonomous without the need of other devices. The approach
taken in this project is to enhance wearable computation devices with the aggregation of functionality
from several devices carried by the user. This approach is particularly appropriate for light weight
devices such as head mounted displays that have an absolute maximum size and weight for the user
to wear comfortable and have a fashionable appearance. The project will produce a series of
wearable computational devices to support head mounted displays and watch computing devices in
user interaction, sensing, and device memory. The main goals of the project are to increase the
functionality and reduce the energy consumption of the wearable devices. (Suitable as PhD project)

Empathic Conferencing
Project Summary: The goal of this project is to conduct research on how wearable computers can
be used to capture and share emotional experiences. In recent years there has been a lot of research
conducted on how wearable computers can be used to create new types of collaborative experiences.
For example, wearable computers such as Google Glass have cameras on them that can be used
to stream video to a remote person and allow them to see what the wearer is seeing. However there
has been much less research on sharing people's emotional experience. In this project we will explore
how simple physiological sensors can be used to capture a user's emotion and then share that with a
remote partner. For example, heart rate and skin conductivity sensors can be used to detect when a
person is feeling excited, and the visual and audio cues could be used to convey that excitement to a
remote collaborator. (Suitable as PhD project)

Enhancing the social dining experience using augmented reality
Project Summary: This project will investigate a novel method of engaging older adults in meaningful
mealtime social interactions through the use of Augmented reality technology. We will develop a virtual dining system that aims to: (1) facilitate interpersonal interactions; (2) elicit positive emotion; and (3) enhance meal consumption in socially isolated older adults. Information collected will inform the design of a larger "remote dining network" that is ripe for commercialisation. This research will be developed in collaboration with our partner, Test Kitchen, a social enterprise aiming to create positive social and emotional dining experiences for older adults. The team will facilitate the development of two virtual dining booths, the essential interactive software and evaluate the effectiveness. It will involve the use of depth cameras to capture gesture based interactions, stereo projection and Microsoft Hololens to enable the experience. (Suitable for honours or PhD).

Face to Face Collaboration Using HoloLens
Project Summary: The Microsoft HoloLens hardware combines a see-through head mounted display
with excellent indoor tracking, and so provides an ideal platform for Augmented Reality. In this project
we want to explore how the HoloLens could be used to enhance face-to-face collaboration.
The project will involve developing an example HoloLens application that will allow two people in the
same room to view and interact with the same virtual content. This will build on earlier work that we
have done in face-to-face AR interaction [1][2]. In addition we will explore novel interaction methods
such as using virtual cues to show where people are looking, and enabling users to see from each
other viewpoints. (Suitable for Vacation Scholarship)

Gaze based remote conferencing
Project Summary: For a number of years people have been studying how head worn cameras
(HWCs) and head mounted displays (HMDs) can be used for remote collaboration on physical tasks.
The HWC allows a remote expert to see what the local user is doing, while a HMD can allow the
remote expert to provide Augmented Reality (AR) virtual cues overlaid on the local user’s view of the
Updated 19/06/2017 32 | P a g e
real world to help them complete the task. For example, in a remote maintenance task, workers using
a wearable AR interface were able to reduce their task performance time by up to 30% [1].
In face-to-face conversation gaze provides information about where a person is directing his or her
attention and so it could also be an important cue in remote collaboration. Previous research has
found that sharing gaze between two remote collaborators significantly improved performance on a
desktop visual search task, compared to audio only communication [2]. However there has been little
research conducted on sharing gaze cues from a wearable collaborative system. In this project we
want to explore the effect of adding gaze tracking to wearable systems for remote collaboration.
The work would extend our earlier pilot work in this area [3] and involve the following: Background
research on gaze tracking in collaborative systems, Create a prototype system integrating a HMD,
HMC and eye-tracker, Conduct user studies with a variety of physical tasks, and Write research
report. (Suitable for Vacation Scholarship)

Spatial Augmented Reality Design Tools
Project Summary: Currently the design of manufactured high-end instrumented facilities (such as
command centres and control panels) is one of working almost entirely in the virtual world. The
physical space and layout of such systems demands high-level 3D spatial visualizations from the
stakeholders. Instead of visualizing a command centre with virtual reality tools or expensive physical
prototypes, this project will explore white painted lightweight wooden objects that would be built to the
external dimensions of the major components of the centre and the details of the workstation will be
projected onto them via large scale augmented reality.
The current process of decision-making is time consuming. A major effort is the externalisation of the
clients’ needs and requirements. Normal practices require a large number design meetings iterating
over concepts that are present as either engineering drawings or 3D static renderings. The use of
animations with fly-throughs and guided tours allows for a more immersive experience, but the clients
lack the tools to manipulate the concept themselves.
This project wishes to investigate a set of novel tools that allows design teams to manage a process of
the clients to manipulate the design concepts. To do this, we will place the clients in physical
environment that emulates the final high-end instrumented facility. The end users will be able to view
the command centre from any vantage point by merely walking. Physical moving the physical
prototypes or manipulating the virtual information projected onto the prototypes can modify the
configuration of workstations or controls on the panels.
To make these tools useful for the manufacturer, this new design methodology must be embedded in
the company’s current design process. Issues of data transfer, operation semantics, workflows, and
process planning will have to be addressed. (Suitable as PhD project)

Storytelling of Big Data
Project Summary: This project is concerned with the development of storytelling tools to allow a user
to develop multimedia-briefing presentations. In essence presentations that provide a non-linear
means of presenting a set of data points and facts to validate a set of augments. The briefing is not a
written document, but an interactive tool to provide a more complete picture of how the data and facts
support a set of conclusions. The order of the presentation is driving by the particular nature of the
information and the recipients of that information. What is unique about this approach is the end users
are able to drill down in real time to expose more detail on demand. Linear text documents do not
support this functionality.
The storytelling tool has three main parts: 1) collection, 2) authoring, and 3) presentation. The
collection phase supports the user in identifying potential important pieces of data and particular facts
to support a particular conclusion. These must be readily available to the user for the construction of
Updated 19/06/2017 33 | P a g e
the final augment. The authoring phase provides the user the ability to construct an interactive
multimedia presentation to justify the conclusions drawn from the data and facts. These presentations
are chosen from the set of styles that best support the types and forms of augments presented for the
particular domain of the user. Because the presentations are stylised from a set known forms of
augments, the tool is able to provide very high-level support to the end user. Final the presentation will
be interactive. This interactive nature of the presentation allows for a non-linear presentation of the
information. The particular people viewing the presentation guides the order and pacing of the delivery
of the information. (Suitable as PhD project)

to directly modify VP entities. By crafting, realizing and evaluating a constraint driven AR user
interface for CAD tools, this project aims to enhance users’ spatial reasoning capacity for numerous

Virtual Reality Brain Training Tools
Project Summary: This project will investigate the use of simulation systems to support medical
applications. The study will explore how Augmented and Virtual reality systems can be employed to
develop therapy and training applications. Current research has demonstrated positive outcomes in a
diverse set of medical applications. For example, cognitive performance can be improved in
Alzheimer’s patients by employing simulation systems with exercise [1]. The reduction of pain can also
be achieved through the use of immersive Virtual Reality systems during wound care. More recently
the use of a virtual reality system has been demonstrated to alter the pain thresholds for patients
suffering from neck pain [3]. This project will investigate how a set of virtual reality brain training tools
can be developed to further understand aspects of psychology, pain and cognition with the aim of
developing therapy applications. (Suitable as PhD project)

Visualising and Interacting with Large Graphs of Big Data
Project Summary: Current collections of the big data in many cases can be presented as one large
graph. Recent technological advances have produced very large data sets that can be presented as
graphs that allow humans to discover and comprehend previously hidden information. This information
presentation strategy is employed by intelligence agencies that monitor social network data to identify
possible terrorist attacks, by biologists to explore interactions between cell systems, and by engineers
to explore complex software architectures. As the size of the data sets increases exponentially,
currently known visualization techniques fail to present easily understandable data, and the need to
find new methods of information presentation to support informed decision-making is an open
research question. A current open research question is the need for better methods that allow users to
understand and visualise large networks. This project will extend the science of human interaction with
large graphs by developing new paradigms that present entire graphs employing abstract graph layout
Updated 19/06/2017 34 | P a g e
algorithms and novel input techniques. The goal of developing these methodologies is to reduce the
cognitive overhead that is the key limiting aspect of current visualization methodologies.
Some particular issues for visualising and interacting with large graphs are as follows:
When the number of nodes of a graph approaches or exceeds the number of pixels on the
computer monitor, how is the graph presented and how can the user interact with that graph?
How is the major underlying structure of interest presented to the user? This is of particular
interest when multiple graphs are aggregated together.
What are the appropriate methods of visualising and interacting with graphs of known data
sources/types? This question addresses the issue of tailoring tasks and interactions to graphs from
particular data sources. (Suitable as PhD project)

Accurate numerical solutions for satellite orbits
Project Summary: The equations governing the motion of a satellite in relativistic space-time are
derived from geodesic equations (Misner, Thorne and Wheeler 1973). The equations of motion are
coupled and non-linear which often means standard numerical methods fall short of the mark. This
project will attempt to utilise symplectic integration schemes (Hairer, Lubich and Wanner 2006,
McLachlan 2006) with mathematical software such as Mathematica to visual satellite motion in
relativity. (Suitable as PhD project)

Applied mathematical modelling in nanotechnology
Project Summary: Famous physicist Richard P. Feynman predicted in his historical talk ‘There’s
plenty of room at the bottom’ that the possibility of miniaturization and nano-devices assembling one
atom at a time! And with the recent boom and success in the area of nanotechnology, such prediction
seems within reach. Nanotechnology has shown to be useful in developing future drug delivery and
high performance lithium battery, enhancing structural strength, advancing NEMS, etc. A deeper
understanding of mechanics at the nanoscale is key to better design of nano-devices. In this project
the student will concentrate on classical applied mathematical techniques for problems that would
incur high cost to investigate experimentally or using computational methodologies. (Suitable as PhD

Approximation of Convex Sets
Project Summary: It is well known that convex polytopes are not good approximations for smooth
convex bodies, such as balls in d-dimensional space. The traditional polytope approximation of a ball
suffers from the curse of dimensionality problem in high-dimensional space. In contrast,
approximations of the ball by zig-zag sets such as those proposed in Cheang and Barron (2000) and
Arstein-Avidian et al. (2005) achieve much better approximation rates. Cheang and Barron (2000)
showed that a threshold of a linear combination of c(d/E)^ 2 half-spaces is needed to achieve an
accuracy of E for such an approximation. Arstein-Avidian et al. (2005) improved the result to show
that only c(d log(1/E)/E^2) indicators of half-spaces are needed. But their result only holds with high
probability 1 – e^{-cd}. More recently Cheang (2010) used a single-hidden layer perceptron neural
network implanting the ramp sigmoid activation function to approximate the indicator function of a d-
dimensional ball and used c(d/E)^ 2 ramp sigmoids to achieve a relative accuracy of E. The goal of
this project is to improve on the accuracy of the Cheang (2010) result for the approximation with ramp
sigmoids and also to explore ways of sharpening the result of Arstein-Avidian et al. (2005). (Suitable

Collision probability modelling for low earth orbit space satellites
Project Summary: With the present day technological progress, military, communicational,
commercial and scientific applications have dominated an impressive number of spacecraft launches.
Today, providing many services from space such as communications, weather forecasts, television,
remote censoring of the environment and navigation have all become an accepted part of daily life.
The increased number of satellites has increased debris in the low earth orbit region (2000km height)
and arising from various explosions and collisions. The [1], US Space Command in Colorado Springs,
has catalogued a total of 9,174 trackable objects in space which have dimensions greater than 10cm,
and of these, 6,313 are considered to be debris, and the rest are believed to be active payloads. The
major and the most recent collision between two intact artificial satellites namely, Iridium 33 and
Kosmos-2251 in low earth orbit occurred on February 10th 2009 which generated almost 2000
individual debris in space. This uncontrollable artificial debris has a significant disturbance on
operational satellites, and therefore calculating collision probabilities with a high degree of accuracy
has become a timely necessity. The scope of this study is to build new models for calculating the
probability of collision between two space objects, and incorporating the assumptions of a number of
existing models [2],[3]. (Suitable as PhD project)

Exact solutions of the Einstein field equations
Project Summary: The theory of relativity gives rise to some of the strangest and non-intuitive
phenomenon in the known universe. Black holes, warped space-time and the bending of light around
massive objects are common aspects of the theory. It is not often one hears black holes being
discussed in the same context as the Global Positioning System (GPS). However, they both provide
experimental evidence validating Einstein's theory. The field equations of gravity that describe such
phenomenon are given by non-linear, coupled partial differential equations. This project will analyse
the field equations and derive more realistic solutions (Schmutzer 1980, Stephani et al. 2009) that
describe the gravitational field of the earth more accurately. (Suitable as PhD project)

Forward and inverse electromagnetic scattering
Project Summary: When a radio wave meets a dense body, the irregular density of the body
contributes to scatter the radio wave in different directions. In forward scattering we try to predict the
wave spread from our knowledge of the body density. In inverse scattering we try to discover the body
density from information about the wave spread. The work involves knowledge of differential
equations. (Suitable for summer or semester-long research project)

Geometry and geometric issues of atomic nanostructures
Project Summary: It is clear from the various structures seen at the nanoscale that the complex self-
interactions of these structures often lead to symmetric configurations. In satisfying an overall
minimum energy constraint, the system often adopts a symmetric structure that shares the energetic
costs of bending and stretching covalent bonds equally to all components in the structure. By
assuming the symmetric configuration, it is possible to reduce fundamentally complex problems of
molecular structure to problems with are more mathematically tractable and thus derive results which
can be confirmed by experiment and simulation. This approach can also be used to predict ideal
systems and novel structures in certain extreme cases. In this project the student will study geometric
models for nanostructures such as nanotubes, cones and spheres (buckyballs) with the aim of
providing more precise predictions of structural parameters like lengths and radii. (Suitable as PhD

Graphene production, and graphene folding and bubbling
Project Summary: Graphene comprises carbon sheets of one atomic thickness. The production of
graphene that has uniform electrical and mechanical properties is a major technological challenge,
since with present production methods the graphene tends to inherit any flaws or dislocations that are
apparent in the host metallic material. An ideal production method might involve a sequential
technique rather like that used in conventional weaving with a loom. Once graphene is prepared, it
needs to be transferred onto whatever device is being manufactured, which is usually done with a

metal stamp. On being released from the stamp, graphene tends to crumple and stick together
forming folds and bubbles, both of which are highly undesirable. This project will analyze possible
methods for sequential graphene production, and the mathematical modelling of graphene folds and
bubbles. (Suitable as PhD project)

Harmonic Analysis: Developing the theory of function spaces on spaces of homogeneous type
Project Summary: In the mathematical field of harmonic analysis, the functions we study have
traditionally been defined on Euclidean spaces R^n. In recent years, there has been much interest in
the new setting where a Euclidean space is replaced by a more general space of homogeneous type:
a set X equipped with a quasi-metric and a doubling measure. This project will focus on developing
the theory of function spaces such as Hardy spaces, Bounded Mean Oscillation, A_p weights and
reverse Holder weights, the relationships between them, and the operators that act on them, on
spaces X of homogeneous type. We will also consider dyadic and multiparameter versions of the
theory. (Suitable as PhD project)

High precision modelling of satellite orbits
Project Summary: Space based satellite technology is now part of everyday civilian life. With a
steady increase in the number of active satellite constellations, highly accurate orbit prediction models
are required. The current theory of gravity as proposed by Albert Einstein in his general theory of
relativity describes gravity as a manifestation of space-time curvature. Despite experimental evidence,
orbit prediction models are currently designed from a classical framework where the effects due to
relativity are implemented as a modification to classical theory (Ashby 2003). This project will attempt
to design a fully general relativistic orbit prediction model, where the first problem will address the orbit
of a satellite using the well-known Schwarzschild solution (Misner, Thorne and Wheeler 1973).
Extensions can be made to more accurately describe the gravitational field of the Earth using currently
known alternative solutions (Stephani et al. 2009). (Suitable as PhD project)

Modelling methane storage using nano-bottles
Project Summary: The traditional storage of methane involves the gas stored in a high-pressure
environment. This presents environmental hazards for applications requiring a lot of methane, such as
for vehicle fuel, domestic cooking and heating, because of the dangers of explosion. A new storage
mechanism for methane involves nano-bottles, which combines the advantages of a high - pressure
vessel and adsorbents, but requires a lower pressure and thus presents less risk of an accident. In
this project, the student will study models for new storage possibilities for methane using applied
mathematical modelling in nanotechnology. (Suitable as PhD project)

Nanoscaled oscillating systems
Project Summary: Nanoscaled structures such as carbon nanotubes and fullerenes undergo atomic
interactions that are described by van der Waals forces. These can lead to extreme accelerations, and
velocities, and in the case of oscillating systems, to ultra-high frequencies in the gigahertz regime. In
terms of creating novel electronic devices, these high frequencies regimes might be important. By
modelling the structures as surfaces with uniform atomic densities and the van der Waals interactions
using a 6-12 Lennard- Jones potential, we can make predictions regarding these systems including
derivation of formulae for the frequency that are often in good agreement with molecular dynamics
simulations. This project examines models to calculate the force to predict the behaviour of various
oscillating systems. (Suitable as PhD project)

New methodologies for Nonconvex and Nonsmooth Optimization
Project Summary: Nonconvex and nonsmooth optimization problems (NNPs) are not tractable by
current available techniques. NNPs arise in finance, biology, medicine, and engineering problems, so
it is important to devise new ways to tackle them in their original, nonsmooth/nonconvex formulation. A
fundamental tool for doing this is duality theory, by which we associate with the original problem
(called the primal problem) another problem (called the dual problem). Research in this area will
develop:
a. new kinds of dual problems, by introducing new augmented Lagrangians. The theoretical aim
here is to establish zero duality gap and strong duality for the corresponding duality schemes, and
b. to devise new solution methods for solving the dual problem, exploiting (when possible) the
structure of the problem.
The theoretical aspects of this project rely on modern tools provided by variational analysis in infinite
dimensions. This includes non-smooth optimization, convex analysis, nonsmooth analysis, and
functional analysis. The new methods will be tested on concrete instances to determine which
Lagrangian structure is more convenient for certain types of problems. (Suitable as PhD project)

Adaptive Free-Space Optical Communications
Project Summary: Over the last few decades the uptake of FSO transmission has been limited by
attenuation due to cloud and fog, plus scintillation fading cause by small variations in the refractive
index of the atmosphere. ITR has shown, both in theory and practice, that channel coding methods
are able to address the fading issues and provide reliable and high-speed communication
channels. Recently our institute has started research into adaptive transmission methods for FSO
communications. Adaptive methods have been used very successfully in fading RF channels for
many years, but so far there has been little use of this approach in optical communications. Our initial
investigations indicate that significant performance gains are possible in FSO links. HDR research in
this area will develop these adaptive techniques, including dealing with practical issues such as the
need for rapid synchronisation and the power and bandwidth limitations of real transducers. (Suitable

Coding and Signal Processing For Future Fibre-Optical Communications
Project Summary: Optical communications offers many advantages compared to its radio frequency
counterpart. Optical carriers have a much higher carrier frequency, allowing for significantly higher
information bandwidth. Currently, technological advance in optical communications is overwhelmingly
driven by breakthroughs in physics and photonics. As photonics technologies mature, and data rates
increase, higher-order nonlinear physical effects and dispersion in the medium cannot be ignored
(especially for long-haul transmission). Advanced digital coding and signal processing techniques
become increasingly relevant to address these channel impairments. The aim of this project is to
answer questions concerning data transmission over optical channels.
The project will:
- Develop the mathematical tools required for analysis of optical channels
- Develop new coding and modulation techniques for optical communications

MIMO and modulations in visible light communications
Project Summary: To efficiently use the radio frequency (RF) spectrum is an important area due to
the scarcity of the limited spectrum bandwidth. Despite the efforts to improve the RF spectrum
efficiency, the data throughput demand has outpaced the development. Optical wireless
communication has shown the potential to bridge the demand gap due to the wide bandwidth
availability of the optical spectrum. The unregulated and easily available bandwidth (over terahertz)
provided by Visible Light Communication (VLC) is one of the main factors that gives these systems an
advantage over the existing radio frequency (RF) communications. To use visible light for data
communications has gained much attention recently and is developing as a viable and beneficial
communication technology, especially for short-range indoor systems. The advent of high-power light
emitting diodes (LEDs) and highly sensitive photo diodes (PDs) and simultaneous use as a source of
lighting and data communication have helped the development of VLC as an attractive as well as
energy-efficient technique for high-speed data communication. This project will investigate novel
approaches to deal with new challenges in VLC, including coding techniques for intensity constraints
in VLC systems, single carrier and multi-carrier modulations, etc. In particular, a Multiple-Input
Multiple-Output (MIMO) system will be developed by using multiple PDs and LEDs. (Suitable as PhD,

Positioning by visible light communications
Project Summary: Location-based services are becoming increasingly important. By knowing a
user’s physical location, a mobile device can provide adequate information to the user and support
different mobile applications. For example, we can have navigation applications and
tracking/monitoring applications in our smartphone. To locate a user in outdoor environments, Global
Positioning System (GPS) and cellular-based positioning have been widely used. For indoor
environments, the performance of these systems is degraded because signals are blocked by walls or
infrastructure. Therefore, alternative solutions are needed for indoor positioning. For example,
positioning systems can be built over wireless local area networks (WLANs). However, the accuracy
of these systems depends on whether the indoor environment is complicated or not. The accuracy can
be from one up to several meters.
This project will investigate an indoor positioning system which is cost-effective and provides accuracy
levels within 0.2 meters by using Visible Light Communications (VLC), which is an emerging and
promising research area. The aim of this project is to develop algorithm and system designs for such a
high precision requirement. (Suitable as PhD, Masters, and Vacation Scholarship)

information theory are unable to completely characterise these regions for every application. Our aim
is to develop methods for analysing rate regions that do not rely on complete characterisations. These
methods will revolutionise our understanding of rate regions by bypassing the difficulties of existing
techniques. Outcomes will provide practically relevant properties of rate regions that will enable novel
applications in communications systems. (Suitable as PhD project)

Refinement of fundamental tools in information theory
Project Summary: In information theory, many famous tools or results cannot be applied to
countably infinite alphabets, e.g., strong typicality, Fano’s inequality and one-time pad. It is important
to consider countably infinite alphabets because this is the general case and this usually gives tighter
bounds, faster convergent rates, etc. Recently, we have generalized the aforementioned tools to
countably infinite alphabets due to the observation that entropy is indeed a discontinuous function.
This project aims to generalize more fundamental results in information theory. Students with good
mathematical and analytical skills are preferred.

Adaptive streaming with delay-constraints
Project Summary: In streaming data over wireless channels with delay constraints, the
instantaneous performance is subject to fluctuations of system states such as the queuing traffic and
channel realization. The streaming performance can be improved by adapting the transmission rate
with the instantaneous system states. The project can be divided in two stages. The first stage
focuses on designing and analysing a new coding scheme, namely rate-varying code that is suitable
for adaptive streaming. In the second stage, rate adaptation policy based jointly on the link layer traffic
and the physical layer performance will be developed. (Suitable as PhD project)

Big Data in Cloud Storage
Project Summary: In the era of Big Data, data storage systems storing massive amounts of data
have become an indispensable component of modern networks, cloud computing and network
applications. In a distributed storage system (DSS), data is stored across multiple data centres to
increase reliability against faults and failures of any individual data centre.
Traditionally, data is directly replicated and stored in each data centre. Despite its simplicity, this direct
mirroring approach requires a huge amount of storage capacity in each data centre. Motivated by
network coding, the new generation of distributed storage system will linearly encode the data before
storing, resulting in a significant reduction in the amount of storage needed in each data centre.
Practically, it is of critical importance that a DSS must be efficient, robust and secure. Data in DSS can
be efficiently updated and retrieved. Furthermore, we must ensure that any eavesdroppers should
reveal no information about the data stored in the data centre and that the system can still repair itself
in case of failure even when there are malicious adversaries tampering or jamming the network.
However, the majority of existing work in DSS ignores these efficiency, security and robustness
issues. This project on the other hand aims to fill this gap by using an information-theoretic approach.
We will focus on deriving fundamental limits as well as practical coding schemes that are efficient,
robust and secure. (Suitable as PhD project)

Distributed control and tracking
Project Summary: Classical closed-loop control systems rely on having high-capacity links between
the sensors, controller and actuators. Meeting this requirement is challenging in distributed systems,
especially in controlling over wireless channels. The communication requirements for distributed
control, namely anytime transmission, were established by Anant Sahai in 2001. However, current
practical anytime codes only partially meet these requirements. This project aims at investigating the
impact of these limitations, and developing new communication and control strategies to address
these issues. (Suitable as PhD project)

Distributed Transmit Beamforming for Resilient Communications
Project Summary: The basic idea of distributed transmit beamforming is based on the coordination of
transmit antennas in a smart way such that the received signal at the receiver can be combined constructively, leading to gains in system performance (in the context of reducing power consumption, increasing transmission range or data rate, etc). Transmit beamforming also provides potential benefits by reducing interference and by enhancing security via reduction of information leakage to enemies in a particular direction. Beamforming technique can offer fundamentally new capability to tactical communications networks such as military communications. The objective of this project is to analyse, build and demonstrate a distributed transmit beamforming system for radio communications. Students will be guided to do analytical study, incorporating modelling and simulation, for different approaches in beamforming systems. The project requires knowledge in signal processing and communications as well as good knowledge of programming languages such as Matlab or C.

Fundamental Limits of LPD Communication
Project Summary: In defence and national security, many situations arise where information must be
conveyed in such a way that it either cannot be reliably recovered, or is rendered undetectable by
unauthorised entities. The former scenario is referred to as secure communication – signal detection
is tolerated, but its information content must be undecipherable to all but the intended recipient. The
latter scenario is referred to as low probability of detection (LPD), or covert communication – the
sender cannot even afford its signal to be detected, let alone its information content be
compromised. While over several decades LPD communication has received much attention in the
literature, most of this work has concentrated on solutions based on pragmatic/heuristic
reasoning. Until recently, very little work has been done regarding the fundamental limits of LPD
communications, especially in the context of modern advancements in wireless communication such
as multi-antenna/multi-carrier communication, cognitive radio and software defined radio. Toward this
end, this research project aims to:
- Formulate a generic information theoretic framework applicable to any channel, e.g. AWGN,
binary symmetric, binary erasure, multi-carrier, multi-antenna channels.
- Understand the trade-offs between key design parameters, e.g. signal-to-noise ratio, local
interference, probability of transmission (burst signalling), decoding error probability and detection
probability.
Note that this project will require close collaboration with the Defence Science and Technology (DST)
Group, Edinburgh, South Australia. As such, it is required that potential candidates are Australian
citizens to be eligible for appropriate security clearances. (Suitable as PhD project)

Information theoretic security for networks
Project Summary: Security is an extremely important aspect in modern information technological
infrastructure. Any security breaches to the system can have disastrous consequences, causing
significant financial losses and long-lasting damages. Therefore, it is of critical importance that data
must be stored and transmitted robustly and securely in the networks, against any eavesdropping or
tampering by malicious adversaries. Network coding opens the door to many interesting possibilities
for information security. The use of multiple transmission paths may increase robustness to denial of
service or jamming attacks. It can also provide security against eavesdroppers. This project explores
some of the security implications and advantages of network coding. (Suitable as PhD project)

Network coding for multimedia multicast
Project Summary: Network coding is a recent breakthrough in telecommunications network
research. Some attractive features of network coding include the efficient use of network resources,
higher data throughput rates and increased robustness against network errors. Network coding is
particularly effective in multicast scenarios, where many users require the same data from a single
source. For example, consider streaming multimedia data over the internet from a single source to
multiple users. Investigate the application of network coding principles to the transmission of
multimedia data in telecommunication networks. Of particular interest are situations where users
require multimedia data at different fidelity/resolution levels. For example, some users may require
high-quality video for high-resolution displays, while other users will require low-fidelity video for small
mobile devices. The main purpose is to devise schemes for efficiently transporting multimedia data
from a single source to many users with different fidelity requirements. (Suitable as PhD project)

PART 4: Phenomics and Bioinformatics Research Centre (PBRC) Controlled drug delivery with multi-layered tablets
Project Summary: In order to control the effects of many illnesses, the steady release of a drug into
the body is necessary. However, a drug (in tablet form) is usually only administered a few times per
day, with each dosage leading to a dramatic increase in the drug concentration within the body,
followed by a slow decrease as the drug is metabolised. Fortunately, it is now possible to manufacture
layered tablets, with the drug concentration and release rate varying between the layers. This results
in a more steady release of the drug into the system, and maintains it at a more constant
concentration within the body. In this project, we will tackle this problem from two directions. First, we
will calculate the rate of drug delivery assuming that we know the concentration of the drug within
each layer and also the rate at which each layer dissolves. Second, we tackle the more difficult
inverse problem: if the required drug delivery rate is known, how could you construct a tablet with a
finite number of layers that would closely replicate the necessary delivery rate. (Suitable as an

Creating nanopatterns by dewetting polymer brushes
Project Summary: Polymer brushes are polymer chains that have been grafted by one end on to a
solid substrate. In the presence of a solvent, the polymer chains are stretched away from the
substrate, however, if the solvent surrounding polymer brushes dries out, the polymer brushes
collapse onto the substrate in a compact layer. Molecular dynamics simulations have shown that as
the brushes collapse, they can form nanopatterns on the substrate, with the type of pattern depending
on the grafting density and the amount of solvent. In this project, we will test the robustness of these
conclusions using partial differential equations, in much the same way as Murray describes the
patterning on mammalian coats (eg leopards and zebras). (Suitable as an honours project)

Modelling of fluid and solute transport in non-uniform, periodic capillaries
Project Summary: The flow of fluids and transport of suspending particles in capillaries has attracted
a lot of experimental and theoretical interest in recent years. The interest is partly inspired by the
potential for commercial exploitation in the area of microfluidics and nanofluidics applications in
chemical and pharmaceutical industries. However, inspiration also comes from a desire to understand
a range of natural phenomena, such as arise in plants. We have an interest in extending our recent
efforts to model fluid flow and particle transport in periodic tubes to more general tube conditions, on

Modelling of salt and water transport in plants
Project Summary: Abiotic stresses such as high salt levels in soils can severely affect cereal crop
health, development and grain yield. Currently, high salinity affects two-thirds of Australian cereal
crops. To increase plant salinity tolerance it is necessary to manipulate the transport of ions (e.g.,
sodium and chloride) through a plant. However, this requires knowledge about how ion transport
through a plant occurs. In particular, it is necessary to identify the key points in this transport pathway
to target in order to generate a salt-tolerant cereal variety. For example, is targeting the initial influx of
ions from the soil the best method for increasing plant salinity tolerance, or should more effort be
directed towards increasing the compartmentalization of ions in the shoot? None of the existing
models of water and solute transport in plants are currently suitable for analysing the transport of ions.
This project aims to develop detailed mathematical models of water and solute transport through plant
organs and tissues, which will be compared with physiological measurements of fluxes and
accumulated ion concentrations. The overall aim is to aid understanding of the biophysical
mechanisms and processes responsible for increasing plant salinity tolerance. It is envisioned that the
results will help guide plant geneticists and plant breeders in their search for specific genetic traits that
enhance a plant's ability to tolerate salinity. (Suitable as PhD project)

Modelling of surface forces in ionic liquids
Project Summary: Ionic liquids or molten salts are very highly concentrated salts in a fluid state.
Such systems feature prominently in many chemical industry processes. However, their behavior has
not been completely nor adequately quantified. In particular, how ionic liquids influence the interaction
between macroscopic surfaces is not known, with conflicting experimental studies confusing the
picture. This is a theoretical project aimed at developing a mathematical model to describe the forces
between macroscopic surfaces in the presence of an intervening ionic liquid. The project involves the
application of advanced statistical mechanical models to help understand how ionic liquids influence
the forces. We shall compare the results with published data as well as new in-house surface force
measurements. (Suitable as PhD project)

Sequential data analysis by integrating hidden Markov modelling with domain knowledge
Project Summary: Hidden Markov Models (HMMs) are statistical models of sequential data that
have been used successfully in many applications in artificial intelligence, pattern recognition and
modelling of gene sequences. This project aims at developing new statistics modelling approach to
integrate conventional HMMs with experts’ prior knowledge (domain knowledge) to improve the
capacity and the accuracy of the HMMs.
Previous works on HMMs focus on how to capture the statistic information from the sequential data
and the relationships between events in time sequences. In this approach, we will develop new
structure for HMMs, likely the multilayered and coupled structure, to represent domain knowledge,
structure information as well statistic information into individual models. The developed novel HMMs
will be applied to biology and health science. (Suitable as PhD project)

PART 5: Future Industries Institute (FII) Controlling Nanopatterns from Polymer Brushes.
Project Summary: Nanopatterned polymer surfaces are important for applications with controlled
mechanical properties. Polymer brushes grafted onto a solid substrate can, depending on polymer
interaction with the solvent, either stay extended or collapse. By controlling the nature of the solvent
as well as its amount, we can control the patterns formed by polymer brushes, and the hence
mechanical properties of such layers.
The properties of polymer layers grafted on a solid surface will be studied using atomic force
microscopy (AFM). AFM is a powerful characterization tool for materials science, capable of revealing
surface structures with superior spatial resolution (nanometer scale) as well as mechanical properties
(softness, adhesion, deformation) of such surfaces. (Suitable as Honours, MSc or PhD project)

Thin Films from Ionic Liquids
Project Summary: When a liquid drop contacts a solid surface a thin film can spread ahead of the
bulk liquid at the three phase contact line region. These films are referred to as precursor films. They
are formed when intermolecular forces of attraction between solid and liquid are strong enough to
induce spontaneous spreading. Spreading patterns in such films are influenced by the nature of the
liquid (e.g. its volatility) and the solid.
The morphology and extent of precursor films formed by ionic liquids will be studied by atomic force
microscopy (AFM), while elemental surface analysis will be probed with X-ray photoelectron
spectroscopy (XPS). (Suitable as Honours, MSc or PhD project)
