Computational methods for multi-scale structural optimisation

Structural optimisation is a powerful computational methodology for finding high-performing designs for structural components or material architectures. For example, what periodic scaffold would provide the highest possible stiffness for its weight?Solving such a problem computationally requires an understanding of the relevant equations required to model the physical properties of interest, as well as efficient implementation of a range of numerical methods including finite elements, finite differences and optimisation.With recent developments in 3D printing technologies it is now possible to manufacture …

Blockchain's application to infrastructure funding

While Blockchain's application as a cryptocurrency is relatively well-known, its application to broader business applications is often misunderstood or underestimated. As an "incorruptible digital ledger of ... transactions that can be programmed to record ... virtually anything of value" (Tapscott & Tapscott, 2016), this technology holds the potential to radically simplify how business opportunities are funded and controlled. This research seeks to understand how the block chain may be used to improve infrastructure funding and control by developing a model …

Materials discovery and design from quantum mechanics-based computational approaches

Understanding novel physics in nanoscale materials is critical for the development of modern electronics technology.However, such delicate materials are difficult to manipulate and characterize experimentally because of their tiny size. This raises the conundrum of how to proceed forward quickly with exploration and subsequently design of properties.In principle, materials properties are determined by the electronic structure. Quantum mechanics based computational approaches are able to address fundamental electronic, optical and magnetic properties in such materials.This provides a powerful complement to the …

2D heterostructures for future electronics

The traditional approach to the miniaturisation of electronic devices is coming to a halt. Experts agree that the Moore’s law prediction of doubling the number of transistors per chip every two years will cease to be fulfilled in 2020, as the heat produced in small structures cannot be cooled down quickly enough.However, by reducing the size of the device, the quantum nature of atoms and solids can be turned into an asset. By exploiting the phenomena occurring at these scales, …

Understanding how structure influences electronic properties in molecular films

Organic electronic materials based on small molecules have a range of interesting applications: they enable lightweight, flexible devices that can be biodegradable and very cheap to manufacture.One challenge working with small molecules controlling how they crystallise into a film, since this affects the electronic properties of the resulting device. Since a wide range of parameters affect the way the film crystallises, this can be a complex problem to understand and control.The aim of this project will be to investigate the …

Accounting for infrastructure and cost-benefit analysis in the assessment of major projects

Infrastructure is vital to improving Australia's living standards and productivity, and accounting plays a key role in how we plan and pay for these projects. The Australian Infrastructure Audit has outlined a new, strategic approach to assessing our nation's infrastructure needs and has highlighted that improvements are needed in infrastructure project appraisal, selection and reporting of cost/benefit analysis. This topic brings together theory and practices from accounting, finance and economics to examine these events in more detail and answer the …

Finite element methods for modelling the deformation of polymers

The finite element method (FEM) is by now a well-established and widely accepted approach for modelling the deformation of linearly elastic materials.In this project we will explore which FEM approach and constitutive laws may be applicable for modelling polymers, which have more deformation behaviour than a simple elastic material. Our long-term goal is to be able to accurately model the deformation of polymer bioscaffolds fabricated with the novel melt-electrowriting (MEW) additive manufacturing process. …

Mitigating vehicular crashes into masonry structures using innovative damping technologies at wall edges

With population increases in major cities accompanied by increase in vehicles on road and waterways, structures such as columns in buildings and bridges as well as walls in buildings that are adjacent to the roads or waterways become vulnerable to vehicular crashes. These impacts cause damage or failure to the structure and injuries/deaths to passengers and users of the structure.This project will evaluate the vulnerability of one of those structures to credible vehicular crash and the effects of controlling parameters. …

Mitigating vehicular crashes into masonry structures using innovative materials technologies at impact zone

Our structures are normally not designed for random and extreme loadings such a vehicular impacts. Buildings and their columns at road frontages and bridge piers are vulnerable to vehicular impacts which result in extensive property damage, harm to people and disruption of normal lives.This project will consider the use of new materials technology and advanced modelling techniques to design critical members of buildings and bridges, or to retrofit existing vulnerable walls and columns in order to mitigate the adverse effects …

Business process ecosystems - definitions, structures and properties

In today’s dynamic business environment, organisations aspire to develop their abilities to rapidly adopt ever-evolving change.Some strategies to achieve this daunting task are:designing and developing agile business processesimplementing systems that are robustdeveloping staff with process-thinking and process-centric culture.However, experience and empirical data tell us that these strategies can only be successful if designed rightly for the context in which the organisation exists.Our view is based on complexity theory, and therefore we call these contexts under which a BPM initiative is …
