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.

RIIS Hub’s research and insights – related to improving the resilience of Australia’s Road and Rail infrastructure – reached a global audience at the 8th International Conference on Road and Rail Infrastructure conference in Croatia (CETRA 2024).

CETRA 2024 is a forum for connecting scientific and industry representatives, enabling discussion, dialogue and the exchange of ideas to solve issues associated with the road and rail sector.

Professor Nasser Khalili, RIIS Hub Director, gave the Keynote lecture, providing insights associated with developing ‘A Constitutive Model for Hydro-Mechanical Analysis of Granular Materials Subject to Cyclic Loading’.

About CETRA

The CETRA conference has established itself as a venue where scientific and professional information from the field of road and rail infrastructure is exchanged. The idea on linking research organisations and economic operators has been the guiding concept for the realisation of this conference.  Conferences of this kind are undoubtedly a proper place for bringing closer together the economy and university operators, and for facilitating communication and establishing greater confidence that might result in cooperation on new projects, especially those that contribute to greater competition. Lectures organised in the scope of the conference are based on interesting technical solutions and on new knowledge from the field of transport infrastructure as gained on already realised projects, projects currently at the planning stage, and those now under construction, in all parts of the world. In addition to authors from the academic community, lectures were also presented by practical authors, the idea being to ensure the best possible synergy between the theory and practice.

Although the transport needs of nations around the world differ in detail, there is much benefit to be derived by sharing research findings and practical experience.  CETRA Conference aims to provide a forum for dialogue on important issues across all disciplines and aspects of the road and rail sectors. The main gaps to be filled are those between researchers and practitioners in design, construction, maintenance, and management of transport infrastructure systems, especially regarding an increased need for sustainable and resilient transport systems – with minimum environmental impacts and able to withstand disruption and absorb disturbance by adapting to changing conditions, including climate change. CETRA 2024 attracted many papers and presentations from 39 countries and 136 institutions (from that 64 universities). More than 149 papers (from 208 submitted) were presented at the conference and are grouped together in the proceedings entitled Road and Rail Infrastructure Viii. The papers are conveniently divided into twelve chapters and one chapter regarding PhD students with extended abstracts.

UNSW RIIS Hub Student

Mahdi Zakerzadeh  also had his paper “Experimental Investigation on the Effect of Crumb Rubber on the Mechanical Behaviour of Stone Mastic Asphalt (SMA)” accepted for presentation to the program on Day 3 Friday 17th June supported by his Supervisor Dr Babak Shahbodagh

Abstract

The utilisation of crumb rubber through a dry process addresses the challenges of tyre recycling and promotes environmental sustainability. This study aimed to investigate the mechanical behaviour of the Crumb Rubber Stone Mastic Asphalt (CR-SMA) mixture. The response surface methodology (RSM) is adopted to explore the impact of independent variables, such as binder content, Crumb Rubber (CR) content, processing time, and CR size, on the variables controlling the mechanical response of the mixture. To comprehensively evaluate the data, the moisture susceptibility, resilient modulus, and fracture energy of the asphalt mixtures are studied using Analysis of Variance (ANOVA). The study successfully achieved an optimum CR-SMA mixture design by enhancing resistance to moisture damage, resilient modulus, and fracture energy, contributing to an improved understanding of the mechanical performance criteria. A quadratic polynomial model aligned with experimental results is proposed, providing reliable predictions of the material performance with an acceptable level of accuracy. These findings offer a valuable roadmap for future strategies in construction, maintenance, and rehabilitation, particularly within the domain of rubberised SMA pavements. Keywords: Stone Mastic Asphalt (SMA), Recycled tyre rubber, Response Surface Methodology (RSM), Dry-process, Rubberised asphalt mixture.

A year after formation, the RIIS Hub team has gathered in person in Sydney to share milestone progress across the Hub’s five Research Themes and supporting projects.

 

 

 

Opening the event, RIIS Hub Director Professor Nasser Khalili welcomed team members from UNSW Sydney, University of Western Sydney, QUT, University of Melbourne at this first in-person gathering of the growing team, and set the scene for the project updates that followed.

“We are firing on all cylinders, with ninety percent of RIIS Hub projects having started, or about to start, with the support of 22 world-leading professors, 4 post-doctoral fellows, 19 PhD students, multiple partners and the support and collaboration of many others,” Prof. Khalili shared.

Industry partners play a key role in ensuring RIIS Hub projects directly address and solve pressing infrastructure maintenance and industry health and safety challenges, and many were represented in person in the room, or joined via video link. Prof. Khalili encouraging industry that if a research project could benefit an organisation, or people have an interest or ideas for a project presented, to “let us know”, and that their involvement would be “wonderful”.

Throughout the day, RIIS research hub members shared the progress status of projects and research underway or at scoping stage; starting with the problem to be solved, and the potential of science and innovation to transform advanced manufacturing, service, and infrastructure engineering in Australia.

The collaborative, future-focused environment, unique to RIIS Hub was on full display, with the event enabling many team members to meet in person for the first time or reconnect in a dynamic forum for information sharing and learning.

Dr Binghao Li (UNSW) alluded to the RIIS Hub purpose by explaining that teams were working towards, “productive, connected, sustainable and smart infrastructure solutions”.

Also attended by industry partners, the event elevated multiple key challenges being addressed by RIIS associated with maintaining and improving wide-ranging public infrastructure in Australia.

‘Thinking big’ with the audience of science and industry innovators, Professor Wei Gao challenged and reminded that “brave ideas” from the team and partners will improve our world.

Projects overviewed, speed-dating style, were wide-reaching and inherently practical. Topics being addressed by research and system evolution covered corrosion, cleaning and maintenance solutions for infrastructure, along predictive structural integrity solutions and challenges, as well as new ways to address issues associated with aging and/or water-based environments for bridges, buildings, pylons and transport systems. Better health and safety solutions for people working on mine sites were overviewed, as well as new ways to deliver cost- and energy-efficiency to workplaces and homes based on sensor collectors and smarter energy and time-saving solutions and other smart systems.

Multiple RIIS Hub projects harness intelligent systems. The application of cutting edge innovation, including nano sensors, automation, predictive computational modelling, computer generated 3D and enhanced imagery, machine learning, artificial intelligence (AI) and robotics are a feature of many projects, and Prof. Khalili warmly introduced Dr Mohsen Mousavi on the day as the Hub’s “AI guru”.

Chief Investigator Dr Babak Shahbodagh (UNSW) shared that data and physics is informing testing models of some AI frameworks, and that ‘real world’ data is training the system along with complex science, thereby making them “more efficient than existing systems”, and hinting at the computational complexity behind the early advances.

Fundamental scientific discoveries made in some projects will be able to be applied and leveraged in others, as the information is widely shared across Hub researchers, teams and Research Themes.

A presentation featuring industry partner representative James Linke, Director, Financial Manager, Chief Controller of GEOAI, about how they are working with RIIS researchers on a landmark (airport infrastructure) project in Australia was a highlight of the day. Research discovery and application, partner collaborations and client/commercial perspectives was shared as a case study with a ‘win-win-win’ outcome across multiple stakeholders.  Closing the session, Mr Linke thanked RIIS team “for a great opportunity to be part of something that’s going to change the industry”.

The value of the collective idea sharing and digging deep into the science in-person was apparent during highly engaging Q&A sessions, especially on the ‘hot topic’ of ‘digital twinning’. RIIS Hub may be able to shape a consistent definition in a fast-moving technology-driven landscape.
