Advanced vascular models for surgical education, training and diagnosis

Vascular surgery is Australia’s second-most expensive surgical program, primarily due to an aging population with increased incidence of cardiovascular disease, representing 29% of all deaths in 2017.Surgical decision-making regarding whether, when and how to operate on a patient relies on the clinicians’ analysis of 2D and 3D reconstructed images on a computer screen in either the endovascular suite or the operating room.Further, endovascular surgeries require skillful and rapid deployment of vascular prosthetics through tortuous, patient-specific geometries to safety, effectively and …

Thermal comfort prediction/optimisation in buildings using data analysis and machine learning

Despite the claims, recent studies show that currently used thermal comfort prediction models, such as the Predicted Mean Vote (PMV) model, may not entirely represent actual comfort level of occupants due to parameters such as cultural and environmental differences. These models, however, are the basis for control parameters of indoor thermal conditions of most buildings.This discrepancy between occupants’ preference and building operation conditions can have several negative consequences such as high energy consumption, efficiency reduction and health issues.This research aims …

Predicting core temperature for emergency services workers wearing encapsulating clothing

Clothing worn by firefighters is vital for protecting the wearer from the threats associated with doing their job. However, the barrier it creates between the wearer and the environment, as well as the weight and bulk of the clothing, both impair body heat loss and increase metabolic rate leading to a warmer deep body temperature. Consequently, firefighters experience elevated cardiovascular and thermoregulatory strain that impairs their tolerance to work in the heat. Accurate measurement of deep body temperature is invasive …

Guided process analytics for actionable improvement recommendations

Process analytics mainly comprises of data-driven analysis of business processes using the massive amount of event log data captured by information systems in the organisations. Various analytical techniques have been developed to help extract insights about the actual business processes with the ultimate goal of process improvement.However, in the ‘big data’ era, we often face the problem that there is too much data to analyse. Without a clear objective for analysis, the tasks such as extracting the relevant data, analysing …

Strategically aligned online value co-creation for social impact

Social enterprises are businesses that trade to intentionally tackle social problems, improve communities, provide people access to employment and training, or help the environment. The social enterprise sector faces specific problems like keeping a balance between financial performance and social mission, measuring and scaling their impact, attracting sources of investments and managing human resources. Co-creation mediated by digital communities can alleviate these problems when strategically aligned via a better understanding of required capabilities.This research will investigate what constitutes as strategic …

Understanding sector connections of disability carers in online communities

While there has been much focus on improving the capability and capacity of carers, there has been little understanding of how service providers can use online social networks to improve service delivery to meet evolving needs of carers. By understanding the current support structures, information flows, and, most importantly, benefits of peer networks for informal carers, service providers can determine both what services must be delivered and how.A better knowledge of such networks can not only assist in service design, …

Optimally scheduling management when climate windows are closing

Delays in acting in collapsing ecosystems can be catastrophic. With every passing year, the chances that the ecosystem has progressed past some point of no return increases. Yet the research and development needed to develop a new technology can take a long time. Balance between these two dynamic processes is needed to determine the optimal length and effort for developing new technologies. This project will develop a method for finding the optimal schedule for developing technological readiness, social acceptability, a …

Mathematically optimising value of information for biodiversity management

When planning environmental management, data are only valuable if they lead to improved outcomes. As new monitoring technologies and approaches are developed, it is critical that they are used optimally to focus on the most important information gaps. Monitoring technologies should only be adopted if they can deliver improved management utility, and new data should be rapidly gathered in locations where early information could offer warning signals of future ecosystem change. Mathematical and statistical approaches to assessing the value of …

Optimising portfolios of management for the Great Barrier Reef

This project will involve adapting Modern Portfolio Theory to develop optimal management approaches to sustain the Great Barrier Reef. Modern Portfolio Theory is an integer programming approach that allocates resources in risky scenarios where investment options are correlated. It can accommodate significant and unavoidable uncertainties, stochasticity, and correlations between options. A diversified portfolio is less volatile than the sum of its parts, and therefore in order to ensure environmental benefits in the future we should invest in a diversity of …

Innovation in process mining

Organisations store large amounts of data where every step is logged in information systems and available for analysts to reveal the hidden behaviour and performance of the business process. This can range from requests being handled within a government body, claims by an insurance company or orders from an online store.Process mining aims to derive information from this recorded historical organisational data. For instance, business analysts use process mining software to visualise logs and derive information and insights for managers.Ultimately, …

Conservation of ecological microcosms

Ecosystem models are important elements of conservation science – we want to save species, and those species interact with other species.Ecosystem models therefore need to be complex, if they are to incorporate the full suite of species and interactions that make ecology so interesting and ecological management so difficult.Unfortunately, our ecosystem models have been failing a lot recently. We have trouble predicting the outcomes of our management interventions. Worse, we don't know why they're not working.Ecological microcosms offer a way …

Efficient Bayesian computation for stochastic collective cell spreading models

New insights into biological processes such as skin cancer spread and wound healing can be obtained through collective cell-spreading experiments.These experiments involve placing cells in a dish and observing how the population of cells evolve under a variety of experimental treatments and conditions by taking images and using image processing tools.An important component for obtaining insight into these processes is the biological modelling and subsequent calibration of the model to real experimental data.Cells move and proliferate, give birth to other …
