Australia is a land of ‘droughts and flooding rains’*, and when they occur soils can swell or shrink, which can result in damage to buildings and homes, and pose a risk to human life.

The personal and collective financial cost of addressing flood-related structural damage to homes is not limited to Australia. It is an international challenge.
Damage to infrastructure could be minimised or avoided with a better understanding of soil behaviour under different conditions, and RIIS Hub is contributing to global learning on the topic.
To further explore international learnings on the topic, RIIS Hub team recently welcomed eminent scholar and researcher in soil-related structural impacts Associate Professor Mathilde Morvan from the Pascal Institute & POLYTECH Clermont in France to explore potential solutions.
A/Prof Morvan’s current research seeks to develop a better understanding of soil characterisation. She is also looking to develop new, inexpensive diagnostic methods that can predict swelling soils near detached houses.
A/Prof. Morvan’s work has close alignment to some of the and predictive techniques being developed in RIIS Hub’s Theme 3 Research program, where researchers are exploring the effect of temperature on the movement of soils using a thermo-plasticity model as part of flaw detection and failure avoidance research.
During her Seminar to the RIIS Hub team, A/Prof Morvan shared

• The cost of damage due to soil shrinkage and swelling on detached houses is the highest among natural disasters in France after floods.
• While methods for characterising these soils exist, they are generally not affordable for most households, and as a result, this foundational soil understanding is often neglected at building and planning development stages.
• One objective of A/Prof. Morvan’s work is to provide a methodology for characterising these soils, and to find simple. Another is to find affordable methods to help spur more due diligence soil investigations to inform structural planning and help prevent damage to homes during disasters.
• A current project proposes to develop a method for monitoring individual houses in high-risk areas, with the aim of providing reliable data.

Following the presentation A/Prof. Morvan spent 1:1 time collaborating with members of the RIIS Hub team, exploring future research and data sharing.
RIIS Hub Director Prof. Nasser Khalili shared:
“We want to make flood affected dwellings are as ‘safe as houses’, and ensure Aussies and their homes are better-prepared to weather future storms.
“Building a collaborative and close-working relationship with other researchers working on related infrastructure resilience projects is a practical way to expand and share knowledge and learnings at scale, and inform the development of more robust technical solutions to solve similar problems.”

Theme 3 RIIS Hub Research involves multiple universities in NSW (UNSW, UNSW Sydney, Western Sydney University) as well as QUT in Queensland. We note that this visit was made possible thanks to NSW Chief Scientist ‘RAAP’ funding.

PhD student Saeed Khalaj is part way through a three-month internship with Sydney-based Covaris, a leading engineering and technology consultancy which works with clients to solve maintenance engineering and asset management challenges.

A self described ‘ knowledge company’, generating innovation through applied and fundamental research, the Covaris internship opportunity is the result of the relationship forged by membership of The Asset Institute. The Asset Institute is also a RIIS Hub industry partner.

Introducing RIIS Hub Higher Degree Research student Saeed Khalaj

• Based in RIIS Hub’s Queensland University of Technology (QUT) node, as part of Prof Tommy Chan’s team. Saeed began his PhD at the school of Mechanical, Medical, and Process Engineering, QUT in December 2022. His academic qualifications span Civil and Geotechnical Engineering. He published six papers in peer-reviewed journals that were cited 129 times in Google Scholar.
• Saeed’s thesis topic is ‘Degradation Modelling and Maintenance Strategies for Railway Surface Defects Through a Machine Learning Approach’. This research project aims to combine machine learning approaches and engineering knowledge to develop a degradation model quantifying uncertainty sources, which will result in optimal maintenance and inspection strategies for railway track surfaces.
• Saeed has presented different levels of his Ph.D. project progress in symposiums and was awarded the HDR Excellence award at the School of Mechanical, Medical, and Process Engineering, QUT, in November 2023.

All aboard!: Saeed shares internship insights

• The internship at Covaris is allowing me to work closely with the Covaris team in Sydney, specifically with its data science group. After performing literature surveys to investigate failure modes and inspection techniques in renewable energy, I am developing models to predict fault arrivals due to different system conditions.
• Key learnings so far: Working with real-world data is challenging! However, the collaborative environment at Covaris really helps us all to work as a team to better understand and address challenges, and deliver meaningful insights and results. Although we are working with industrial datasets, taking into account the engineering perspective to analyse the results is crucial at Covaris. This leads to delivering meaningful and practical solutions for the clients.

Some of the innovative solutions to keep data insights ‘on track’

Saeed has been very involved in the development of the Bayesian statistics capability at Covaris, and is applying it to two client case studies covering fixed plant and mobile fleet.

• Group meetings with the Covaris’ data team and industry experts are important- the ideas sharing has helped solve some of the data challenges we initially faced. Happily, ‘unstructured’ data and limited access to plant expertise are no longer barriers to research progress.
• Where raw data sources to inform the research were challenging, we implemented a Bayesian statistics approach (a theory in the field of statistics based on the Bayesian interpretation of probability, where probability expresses a degree of belief in an event) to test correlations and drivers of reactive maintenance.

RIIS Hub: delivering on wide-ranging education and training experiences

RIIS Hub is training to a cohort of highly competent and motivated professionals through research and development programs, carried out in partnership with participants from all sectors of the infrastructure industry. Internships are a part of this approach, and enable RIIS Hub research insights and practical solutions to directly address infrastructure challenges facing industry. Internships also enable researchers to experience ‘real world’ research and development (R&D) activities related to their research.

Prof. Nasser Khalili, RIIS Hub Director, is pleased that the Asset Institute membership is already connecting RIIS researchers to a community of research, industry and infrastructure/asset management experts, and spurring student learning opportunities.

“There is real value to being immersed in a working environment, with all of its very unique opportunities and challenges. It allows students to stretch their experiences and apply their knowledge to solve asset management and infrastructure problems, as well as build close connections with industry.

About Covaris

• Covaris (Australia) delivers asset management solutions to Australia and the world.

We were honoured to welcome Professor Lili Du at UNSW on July 15, 2024, where she delivered a seminar on the topic of ‘Robust and Resilient Coordinated and Distributed Route Navigation Systems for Connected Vehicles Subject to Random Communication Delays & Interruptions.’ The seminar was hosted by the RIIS Hub and Civil Engineering’s Centre for Infrastructure Engineering and Safety. 

Dr. Lili Du’s expertise lies at the intersection of transportation engineering, data analytics, and emerging technologies, making her a valuable contributor to the field of civil and coastal engineering. You can find more information about her on the University of Florida website 

Abstract:

In recent years, wireless communication, onboard computation facilities, and advanced sensor techniques have enabled the development of well-connected, data-rich transportation systems, known as connected vehicle systems (CVS). Despite the potential of CVS to smartly route travelers and avoid traffic congestion, researchers have identified a significant issue: as the majority of vehicles become connected, the current real-time information provision and routing methods can actually worsen traffic congestion. This occurs because each connected vehicle still independently selects its shortest path, leading to a misalignment between system performance and individual vehicle route choices. Additionally, those emerging communication and information technologies make our routing navigation systems vulnerable to cyber reliability and security issues, such as communication delays and interruptions. Motivated by this view, our studies have introduced robust and resilient coordinated and distributed route navigation systems for connected vehicles subject to random communication delays and interruptions. Our novel route navigation algorithms used game theories to coordinate CVs’ routing decisions en route to address the overreaction phenomenon and employed robust distributed optimization and advanced computing technologies to enhance the system’s resilience against communication failures caused by infrastructure malfunctions or cyberattacks. Numerical experiments conducted on the Sioux Falls network validated and confirmed the effectiveness of our approaches.
