An advanced approach to fixing wear damaged rails in remote locations using repair technology has been shown to be viable for large-scale use in neutron scattering experiments. Researchers from Monash University and ANSTO collaborated with engineers from the Institute of Railway Technology (IRT), the premier track and vehicle railway research centre in Australia as well as a sovereign heavy manufacturing company to develop a reliable and efficient laser-based rail repair technology.
The team used a nuclear technique at ANSTO’s Australian Centre for Neutron Scattering on the Kowari instrument to evaluate a laser cladding repair technique, which is an established method to repair high-value components in other industries on heavy haul rails. The method could increase the service life of rails and reduce maintenance time and costs, as repairing rails is preferable to replacing them.
The project’s industry partner, an ARC Linkage project partner, has vast experience and expertise in the use of laser cladding technology for manufacturing and repairs in the mining sector. Heavy haul rails repairs, however, present significant challenges to the manufactures as they cannot be performed in the controlled environment of the factory but rather need to be done in the remote areas of the Australian outback.
In research published in the Journal of Materials Processing Technology, they conclude that advanced laser technology could be used on heavy haul rails and that detrimental stresses could be reduced or mitigated from critical regions of the repair. With laser cladding, repairs are made by coating the damaged rail surface with a stainless steel or cobalt-based alloy in single or double layers using laser technology.
“Laser cladding can deposit these beneficial materials onto damaged areas but can also introduce or re-distribute residual stresses,” explained Taposh Roy, Monash PhD graduate, currently a Project Engineer Melbourne Metro Trains.
Investigators used neutron scattering on the Kowari strain scanner on a full-scale railhead to measure residual stresses created by the heat generated by the laser during the cladding deposition process (pictured above). As part of this, the team developed a new procedure to evaluate residual stresses in thick sections of full-scale cladded rails. Only neutrons can penetrate through the deep surface of the rail material, and measure full triaxial stress distribution non-destructively with little preparation.
To acquire measurements in small gauge volumes on a large path length through the steel, they made blind holes in the sample. Taking measurement at the middle of the two holes, also avoided a disturbance of local stresses. The team found that the application of a post cladding heat treatment significantly reduced the residual stresses from the surface and the subsurface of the cladded rails. The method appears to be superior to conventional arc weld based cladding methods, the most common technique to repair wear damage in rails.
“These successful in-house repair trials are very encouraging to explore further the application of this technology as a portable and mobilised unit, that can be deployed to address the rail maintenance problems in remote areas of Australia,” said Prof Anna Paradowska, Industry Engagement Manager, Australian Centre for Neutron Scattering and Conjoint Professor The University of Sydney.
About the Kowari – Strain Scanner
Kowari is a neutron scattering instrument. It is among the best residual stress diffractometers from neutron facilities around the world. Kowari started its operation for users in 2009. After a few years of operation, ANSTO sees a certain future of the instrument. In Australia, they are seeing the major usage being in problems with steel (and to a lesser extent aluminium-alloy) components, particularly welds.
This reflects the nature of Australia’s dominant industries: mining, power generation and transmission, shipbuilding, railways, construction (for instance of sports stadia), life extension of defence assets, and so on.
In Europe and the USA, there is a greater emphasis on higher value-added applications from the aerospace, defence and automotive industries, where composite and other unconventional materials are increasingly being used.

Indonesia has great ambitions for its digital economy and has deployed strategies to achieve its ambitions with a goal to reach USD315 billion by 2030. The 2021-2024 Indonesia Digital Roadmap is set on 4 pillars, namely digital infrastructure, digital government, digital economy and digital society.
As part of its strategy, the government is promoting four important digital skills to accelerate its digital economy. The government believes that the future demand for digital skills will be focused on four areas Artificial Intelligence, Bitcoin, Cloud Computing, and Data Analytics (ABCD). The ABCD skills are projected to help the national economy hit its US$315 billion by 2030 target.
Therefore, the Indonesian government is encouraging young people to start businesses through a variety of free programs such as Beta School, 1,000 Startup Movement, Startup Studio, HUB.ID and IGDX.
“Aside from university disciplines, the ABCD is becoming increasingly important for everyone. I believe that all young people require ABCD,” stated Dedy Permadi, Expert Staff of the Minister of Communication and Informatics, in a discussion forum.
Mastering ABCD technical hard skills apart, Indonesian digital talents are also expected to be proficient in non-technical or soft skills known as the 4C’s, which are Complex Problem Solving, Critical Thinking, Creativity and Communication.
The Director of SDPPI Kominfo, Ismail, expressed his hope that the young generation in Indonesia would capture the golden opportunity for digitalisation. Digitalisation will transform Indonesia from a consumer country to a prominent player in the new normal.
The government recognises the importance of good infrastructure support in boosting the digital economy. As a result, the government is working to ensure an equitable distribution of internet connection networks across Indonesia, particularly in frontier, remote, and underdeveloped (3T) areas.
According to Ismail, the development of ICT infrastructure must meet three criteria: broad coverage, the deployment of a fibre-optic cable network on the backbone, and affordability, which means that the price is reasonable for the community.
Private operators focus on developing infrastructure in high-demand urban areas and, as a result, the digital divide between cities and towns has grown wider. Consequently, the government is beginning to develop 3T telecommunications in rural, underserved areas.
“We cannot rely solely on private-sector investment. To speed up and accelerate digital transformation, the government must invest in infrastructure,” Ismail said emphatically.
The Ministry of Communication and Information Agency and Telecommunications and Information Accessibility (BAKTI) have also worked to improve and expand internet access for public services throughout Indonesia. BAKTI is working with telecommunications companies to build Base Transceiver Stations (BTS) in remote areas of Indonesia.
“We hope to finish building BTS in all remote areas by 2023 and connect them to the 4G network,” Deddy stated.
Indonesia is a vast archipelagic country. So, relying solely on fibre optic cable networks will make it difficult to provide connectivity. As a result, the government is combining the fibre optic cable network constructed with the 150 Gbps SATRIA 1 satellite.
This multifunctional satellite can provide internet access to 150,000 public service locations in Indonesia, including educational institutions, local governments, defence and security administration, and health facilities. This satellite is scheduled to launch in 2023.
The government has begun construction of the first National Data Centre in the Delta Mas Region, GIIC, Cikarang District, Bekasi Regency, West Java Province, in connection with its digital strategy. It will then gradually expand data centres in Nongsa Digital Park in Batam, Riau Archipelago, the new National Capital City (IKN) in Balikpapan, East Kalimantan, and Labuan Bajo, East Nusa Tenggara.
The creation of this government data centre is intended to promote efficiency, effectiveness, state data sovereignty, and national data consolidation as part of the One Data Indonesia initiative. “This (data centre) is critical because government data management is critical to developing society’s transformation into a digital society,” Deddy said.

Riding on Hong Kong’s thriving biotech market and the city’s status as the world’s second-largest biotech fundraising hub, the co-incubation partnership also recognises HKSTP’s impact and success in building a vibrant biotech ecosystem in Hong Kong.
The Head of Incubation and Acceleration Programmes at HKSTP stated that the co-incubation partnership with an international player like the partnering firm validates Hong Kong’s unique and growing status as a global I&T hub helping international start-ups go beyond borders in their global growth journey.
She noted that with a pipeline of seed stage and series A start-up’s already in place, this proves the strength of the HKSTP innovation ecosystem and confirms that Hong Kong is open again for global business and an ideal launchpad for high-growth tech ventures seeking GBA, regional and global expansion.
The Managing Partner of the VC firm stated that the signing of this co-incubation agreement will allow the two parties to incubate and introduce promising global start-ups to scale their businesses in Asia. The firm will continue to leverage its unique cross-pacific networks and investment niches in transformative life science technologies to enrich Hong Kong’s innovation ecosystem with more ground-breaking technologies from North American start-ups.
The programme features co-incubation activities ranging from business development, consulting and training to mentoring sessions for qualified overseas start-ups. Participating entrepreneurs will also create proofs-of-concept and pilot initiatives.
The start-ups will tap into the investment and international business network reach of the firm while also formally joining the HKSTP innovation ecosystem to access product validation, commercialisation and go-to-market expertise from HKSTP and its wider network of partners.
Specialising in investing globally in science and technology-based start-ups, the VC firm has been active in Hong Kong and Asia with its specific focus on nurturing start-ups that aspire to expand to China and Asia. In 2019 it facilitated eight Canadian start-ups from prestigious start-up programmes to come to Hong Kong to gain deeper insights into strategic landing tactics and expansion into the Asian markets. This latest partnership with HKSTP has forged a new level of commitment to the Hong Kong I&T ecosystem.

Taiwan City Science Lab @ Taipei Tech demonstrated a series of cutting-edge AI applications. The lab exhibit advanced AI applications and their research and development results, such as the mobile robot, a AI robotic fish and Campus Rover.
The cross-disciplinary R&D and teaching laboratory aims to be a global technology and talent exchange platform. Massachusetts Institute of Technology (MIT) and Taipei Tech are coming together to jointly established City Science Lab @ Taipei Tech.
“Through developing advanced AI technology and big data system, we plan to make Taiwan the island of high-end technology,” said Yao Leehter, Taipei Tech Chair Professor of the Department of Electrical Engineering.
Yao indicated that Taipei Tech alums highly support the lab. The lab also collaborates with Kent Larson, the leader of MIT City Science Lab, the City Science Lab @ Taipei Tech aims to be an international platform for technology and talent exchange.
Taipei Tech adopts and jointly promotes with MIT to implement the Undergraduate Scientific Research Programme. Known as UROP, the programme provides sufficient resources for students and cultivates a new generation of scientific researchers. The collaboration was initially rolled out in 1969 by MIT’s first President, William Rogers.
For students to learn the most modern and state-of-the-art technology applications, the lab provides advanced equipment for R&D purposes, such as mobile robots. The agile, mobile robot can adapt to complex terrains and is equipped with LIDAR, infrared, and stereo vision sensors, which can draw 3D point cloud maps in real-time and detect and dodge obstacles. The mobile robot is used in decommissioned nuclear power plants, factories, construction sites, and offshore drilling oil platforms. Another mobile robot use case is for patrol, troubleshooting, and leak detection.
In addition, the lab also showcased its R&D results which are the AI robotic fish to the advanced instrumental equipment. The robotic fish is a streamlined robot designed to resemble a real fish. The fish robot comprehends and mimics the motion model of swimming fish through machine learning.
The robot can swim underwater in a simulated way. To perfectly mimic the fish movement, researchers have spent significant time collecting massive movement data from real fish, documenting, and analysing the swimming performance. Afterwards, they utilised AI technology and programme coding to control the motoric movement of the robotic fish.
The team then spent a year adjusting the robotic fish to make the swim movement look like a real fish. Machinery fish propulsion efficiency and excellent swimming performance are considered one of the most critical subjects in bionics.
“The robotic fish is useful for biological research and can also be used to carry out underwater operations and examine water quality,” said Yao.
Recently, the fish robot was involved in movie production. During the designing process, the production house team suggested adding a “cloth” on the fish with fish skin and fish scale to make it more lifelike. The company also came up with the idea to use a magnet to stick the fish scale on the body of the robotic fish. Taiwan Textile Research Institute and the local design research group joined the brainstorming and production process to finish the golden fish’s final look onscreen.
Moreover, The Campus Rover, developed by the team of Professor Yao in cooperation with the Taipei Tech Department of Industrial Design, demonstrated practical AI applications in real life. For example, campus or express hospital service can use the self-charging robot to ensure delivery safety.
Around 30,000 rural homes and communities will soon have access to faster and improved connectivity with an expansion of the Rural Capacity Upgrade programme. 21 new contracts have been signed by Crown Infrastructure partners to accelerate upgrades to towers and broadband connections in areas with poor coverage.
The announcement was made by the Minister for Rural Communities, Damien O’Connor, and the Minister for the Digital Economy and Communications, David Clark. This round of the Rural Capacity Upgrade will see many existing towers upgraded and new connections established in rural areas experiencing poor performance. Areas that will benefit from these improvements include, but are not limited to, settlements in the Far North, Gisborne, the Manawatu-Whanganui region, Taranaki, Southland, and Waikato.
The project is expected to significantly boost the economic productivity of homes and businesses with a slow, unreliable, or unusable connection, Clark noted. The government is committed to improving rural connectivity and is on track to see 99.8% of New Zealanders receive access to improved broadband because of the Ultra-Fast Broadband rollout, Rural Broadband Initiative, the Marae Digital Connectivity programme, and the Mobile Black Spot Fund by the end of 2023, he explained.
The investment in rural connectivity will work alongside Land Information NZ’s rollout of the Southern Positioning Augmentation Network (SouthPAN) service. As OpenGov Asia had reported earlier, SouthPAN is the Southern Hemisphere’s first satellite navigation augmentation service. It will improve the availability and accuracy of positioning, taking it from 5-10 metres to as little as 10 centimetres across the country.
This will boost rural productivity through precision agriculture and horticulture, fenceless farming, and improve the safety of search and rescue in the backcountry. The government, along with private sector contributions, has invested more than $2.5 billion into improving digital connectivity to date.
The government has also released “Lifting Connectivity in Aotearoa”, which sets out the high-level connectivity vision for New Zealand over the next decade. This includes the goal that all New Zealanders have access to high-speed connectivity networks, and that the country is in the top 20% of nations with respect to international connectivity measures.
Last month, the government launched the Remote Users Scheme to provide broadband and connect New Zealand’s most remote communities. Clark had announced the scheme, noting that it would equip as many remote households as possible with the connectivity infrastructure needed to access broadband services. As reported on OpenGov Asia, the Remote Users Scheme will help connect people to online health services and educational tools. Through Budget 2022, $15 million was allocated towards funding the scheme, as part of the broader $60 million rural connectivity package announced earlier in the year.
The Crown Infrastructure Partners (CIP), which was established by the government, will administer the Remote Users Scheme and is calling for applications from potentially eligible households and communities. A request for proposal from Internet service providers will follow. It is expected that new broadband connectivity infrastructure for the eligible areas and households can begin being built in mid-2023.
