A team of researchers at MIT, NTU and the Skolkovo Ins tute of Science and Technology in Russia have used ar fi cial intelligence to help predict and control changes to semiconductors and crystalline materials.

These changes deform their atomic arrangement and cause drama c property changes, aff ec ng the way they transmit light, conduct electricity, or heat, poten ally crea ng new avenues of research on advanced materials for future high-tech devices.

The team’s fi ndings were published in Proceedings of the Na onal Academy of Sciences, authored by Professor Li Ju, Principal Research Scien st Dao Ming, and graduate student Shi Zhe at MIT, together with Mr Evgeni Tsymbalov and Assistant Professor Alexander Shapeev at the Skolkovo Ins tute of Science and Technology in Russia, and NTU President Professor Subra Suresh.

Based on earlier work at MIT, some degree of elas c strain has been incorporated in silicon processor chips. Even a 1 per cent change in the structure can, in some cases, improve the speed of the device by 50 per cent, by allowing electrons to move through the material faster.

Unlike other ways of changing a material’s proper es, such as chemical doping, which produce a permanent, sta c change, strain engineering allows proper es to be changed dynamically.

The challenge, however, is in exploring the full range of possibili es, as strain can be applied in any of six diff erent ways (in three diff erent dimensions, each one of which can produce strain in-and-out or sideways), and with nearly infi nite grada ons of degree.

“It quickly grows to 100 million calcula ons if we want to map out the en re elas c strain space,” said Prof Li.

The team’s novel applica on of machine learning methods therefore provides a systema c way of exploring possibili es and homing in on the appropriate amount and direc on of strain to achieve a given set of proper es for a par cular purpose.

This will enable the crea on of materials tuned precisely for electronic, optoelectronic, and photonic devices that could fi nd uses for communica ons, informa on processing, and energy applica ons.

“This work is an illustra on of how recent advances in seemingly distant fi elds such as material physics, ar fi cial intelligence, compu ng, and machine learning can be brought together to advance scien fi c knowledge that has strong implica ons for industry applica on,” said Prof Suresh.

The team studied the eff ects of strain on the bandgap, a key electronic property of semiconductors, in both silicon and diamond. Using their neural network algorithm, they were able to predict with high accuracy how diff erent amounts and orienta ons of strain would aff ect the bandgap.

According to Prof Li, the method used in this study “is generalisable to other aspects”, which aff ect not only electronic proper es but also others such as photonic and magne c behaviour.

From the 1 per cent strain now being used in commercial chips, many new applica ons open up now that this team has shown that strains of nearly 10 percent are possible without fracturing.

“This new method could poten ally lead to the design of unprecedented material proper es … But much further work will be needed to fi gure out how to impose the strain and how to scale up the process to do it on 100 million transistors on a chip [and ensure that] none of them can fail,” he added.

The work was supported by the MIT-Skoltech program and NTU.

NEW STUDY HIGHLIGHTING CRITICAL CYBERSECURITY RISKS

IN THE AUTOMOTIVE INDUSTRY RELEASEDUS-based so ware development and cybersecurity fi rm Synopsys, together with SAE Interna onal, a global associa on of engineers and technical experts in the aerospace, automo ve and commercial vehicle industries, released a report on automo ve cybersecurity in February.

Titled Securing the Modern Vehicle: A Study of Automo ve Industry Cybersecurity Prac ces, it highlighted cri cal cybersecurity challenges and defi ciencies aff ec ng many organisa ons in the industry.

For example, the study found that 84 percent of automo ve professionals were concerned that their organisa ons’ cybersecurity prac ces were not keeping pace with evolving technologies.

The survey also found that 30 per cent of organisa ons did not have an established cybersecurity programme or team, and 63 per cent tested less than half of their developed technologies for security vulnerabili es.

The Ponemon Ins tute, a leading IT security research organisa on, was commissioned to conduct the study

Other key fi ndings include:

• A lack of cybersecurity skills and resources.

• Proac ve cybersecurity tes ng is not a priority.

• Developers need cybersecurity training.

• Cybersecurity risk exists throughout the supply chain.

As our economy continues to transform, the role of applied learning in higher education has grown in signifi cance. Since 2014, as Singapore’s university of applied learning, the Singapore Institute of Technology (SIT) has grown from strength to strength in nurturing an industry-ready workforce to drive Singapore’s future growth.

Pioneering applied learningA pioneer in applied learning, SIT was set up in 2009 to provide an upgrading pathway for deserving polytechnic graduates to obtain industry-relevant degrees. From an inaugural batch of 500 students, SIT has grown to be a full-fl edged Autonomous University with 7,000 students, off ering 42 degree programmes, including 14 of its own and 15 jointly with renowned overseas universities.

Its growth is backed by a distinctive commitment to engage students in innovative pedagogy by integrating learning, industry and community; and focusing on

off ering applied degree programmes that cater to diverse student profi les and industry needs.

SIT is unique in its applied learning pedagogy. With more than 90 per cent of its undergraduates from polytechnics, SIT has a student population of hands-on learners. SIT elevates their learning experience by instilling in them a mindset of learning by doing, rather than learning for doing, to enhance their industry-readiness.

At SIT, applied learning is weaved into every aspect of a student’s learning journey, whether it is in the classroom or the real world and whether it is during learning or assessments.

Its unique pedagogy of integrating work and study is built upon a solid foundation of industry collaborations and an expanding line-up of programmes catering to emerging economic sectors.

Unlike other universities, SIT has organised its academic staff according to technical domain clusters instead of faculties. This matrix academic structure has stimulated interdisciplinary collaborations and teaching across related disciplines.

Industry-centric educationSIT carries its applied learning approach fully through its curriculum, to create a seamless work-study and highly industry-focused educational journey for its students.

The university boasts close collaboration with various industry partners that opens up to its students abundant opportunities for industry attachments and work-study programmes.

In addition, SIT has also established Industry Advisory Committees (IAC), comprising key industry leaders, to guide the curricula development of its degree programmes. Their feedback allows SIT to continually shape its curricula to ensure its industry relevance.

Industry knowledge is delivered to students every day at SIT, as the majority of its faculty staff are also part-time consultants in their respective industries. Their industry experience and professional

networks entrench a long-lasting industry and academia collaborative relationship that translates to an authentic learning environment for students.

SIT takes its industry focus further with its corps of Professional Offi cers. Drawing on their profound industry experience, these individuals mentor students undertaking industry attachments and projects, guiding and motivating them to maximise every learning opportunity.

Integrated Work Study ProgrammeDemand for SIT graduates is seen in its overall graduate employment rate that reached 92.3 per cent in 2017. A key driver of this positive outcome is the Integrated Work Study Programme (IWSP), a compulsory component for students in SIT-conferred and joint degree programmes.

In IWSP, students spend eight to 12 months working and studying. The extended period enables students to participate in projects with longer timeframe and make signifi cant contributions to the company.

IWSP gives SIT students a fi rm head start to the working world, by exposing them to the latest industry developments, business intricacies and work cultures. The work-study continuum also helps undergraduates transit to their future jobs with lesser eff ort and greater success.

For example, students of the Sustainable Infrastructure Engineering (Land), or SIE (Land), degree programme have gained deep insights into Singapore’s land transport development, through IWSP at organisations such as the Land Transport Authority, SMRT and SBS Transit.

To date, more than 1,300 students from 16 programmes have completed IWSP at more than 500 companies. However, to the industry, IWSP is more than just an attachment programme – it has become a conduit to identify and recruit future talents.

In a preliminary survey of the Class of 2018 conducted by SIT, close to 70 per cent of graduates from SIT-conferred degrees received employment off ers from fi rms where they did their IWSP, and over 90 per cent among those surveyed had secured jobs. In particular, for the SIT Accountancy programme, 92 per cent of the cohort received advance job off ers upon completion of their IWSP.

These results attest to the eff ectiveness of SIT’s approach in enhancing its students’ employability by emphasising on real industry assignments in IWSP.

Diverse engineering programmesSIT off ers diverse, multi-disciplinary engineering degree programmes that are closely aligned with Singapore’s key economic growth sectors. These include aerospace, chemical, civil, electrical power, marine, mechanical, land transport, pharmaceutical, systems and software engineering.

Its curriculum trains students to be professionals with a mastery of deep specialist skills in their chosen disciplines. This creates a distinctive edge to the students’ professional competencies, while building a strong pipeline of specialist engineers to solve increasingly complex industry problems.

Thus far, SIT has introduced several fi rst-of-its-kind specialised degree programmes in Singapore.

Launched in 2014, the SIE (Land) programme focuses on nurturing talents to meet latest demands in railway engineering and has already graduated its pioneer cohort of BEng and MEng students in October 2018.

SIT also introduced the Telematics (Intelligent Transportation Systems Engineering) programme in 2016, in view of the rising impact of telematics in the automotive, avionics and marine industries. This unique programme gears students towards supporting the growth of transportation super-infrastructure in Singapore.

In 2018, SIT unveiled the Aircraft Systems Engineering programme in collaboration with SIA Engineering Company. Built on an interdisciplinary curriculum that intersects engineering, science and a hands-on approach, the focus of the programme is to produce graduates for the aerospace and MRO industries.

All in all, while still studying at SIT, students would have gained a fi rm footing in the workplace and more importantly, made a big step towards becoming catalysts of Singapore’s future transformation.

A er a USD 85 million upgrade and modernisa on pro-gramme, which included employee training and acqui-si on of new tooling and machinery, Eagle Services Asia (ESA), has brought in its fi rst PW1100G-JM engine for overhaul.

A joint venture between SIA Engineering Company and American aircra engine manufacturer Pra & Whitney, ESA is a member of the la er’s worldwide network of MRO facili es for its geared turbofan (GTF) engines.

The Singapore engine centre is now fully enabled to simultaneously overhaul several engine models – the PW1100G-JM GTF engine, the GP7200, as well as the PW4000 family.

“Modifi ca ons to the facility will improve produc vity, reduce set up me and boost effi ciency across opera- ons. Current PW4000 engine customers will also benefi t

from these effi ciencies,” said Mr Brendon McWilliam, senior director for the company’s a ermarket opera ons in the Asia-Pacifi c.

This year, ESA will gradually introduce a new ground-based fl ow system, which will enable visual line of sight on the GTF engine overhaul line.

In the new system, engine modules will move from one sta on to another, improving the visibility of opera ons through the line from disassembly to assembly and test, in contrast to the old engine repair work bay.

Already proven in the automo ve industry, the system improves produc vity while maximising the use of exist-

ing space. At full capacity, the fl ow lines can accommo-date up to six GTF engines at a me.

“This is an exci ng period of expansion and growth for us,” said ESA managing director Yip Ying Kiong. “In addi- on to broadening our capabili es on next genera on

aircra engines, this expansion enables us to invest in our engineers and technicians by training them to handle advanced materials and automa on.”

The GTF MRO network spans three con nents, com-prised of engine centres located in North America (the United States), Europe (Germany) and Asia (Singapore and Japan).

NTU and Germany’s Max Planck Ins tute of Colloids and Interfaces (MPICI) have launched a joint lab to conduct research in ar fi cial senses and develop innova ve robo cs and healthcare solu ons.

These include skin-like wearable devices that not only monitor health and environmental condi ons through smart sensors, but also enhance prosthe c devices with ‘ar fi cial sensing’ capabili es.

This would allow prosthe c devices to restore rudimentary sensory func ons for pa ents who have lost certain senses, such as a er accidents.

Leveraging on advanced materials, ‘skin’ electronics, biomedical engineering, and AI, the new Max Planck-NTU Joint Laboratory for Ar fi cial Senses will also look into developing robo c technologies with sensory capabili es.

For example, robots equipped with sensing feedback can provide customised care by adjus ng their interac on and engagement to suit the pa ent.

The partnership will also conduct research to extend human senses beyond their natural capabili es. This includes developing new sensory technologies that will allow users to see or hear radar frequencies or microwaves, smell infec ons or gene c pa erns, or even sense earthquakes.

Such capabili es can help, for example, safety offi cers detect chemical leaks in a factory, or meteorologists iden fy subtle tectonic movements, enabling earlier earthquake warnings.

NTU President Professor Subra Suresh said, “NTU’s collabora on with the Max Planck Society aims to take robo cs and medical technologies to the next level by combining human senses, AI and machine learning. This will be benefi cial for various industries, especially for healthcare as cu ng-edge medical devices could reduce misdiagnosis, and allow for customised precision medicine to deliver faster, be er care to pa ents.

Located at NTU, the joint lab is also MPICI’s fi rst venture in Southeast Asia.

MPICI is part of the pres gious Max Planck Society for the Advancement of Sciences. Established in 1911,

the Society is one of the world’s leading research organisa ons.

Professor Peter Fratzl, Head of the Sec on of Natural Sciences at the Max Planck Society, said, “Mul sensing with cheap and robust sensors followed by decentral neuronal data densifi ca on will allow devices which act as “intelligent” species, turning big data into clear metainforma on, such as warning signals or “senses/sensa ons”. The possibili es for engineering, environmental technologies, or medical treatment are breath-taking.”

The joint lab will house 30 NTU and MPICI researchers and staff who will also explore mechanical sensing such as pressure and strain, and chemical sensing like smell and taste, and even physiological sensing that usually involves electrocardiograms.

Research fi ndings will be used in the development of ‘exteroceptors’ – sensors that pick up external s muli such as touch, sound, pressure, light, and temperature.

The joint lab will be equipped with advanced materials processing instruments, high-end signals analysers, and human-machine interface and machine learning algorithm-based setups.

It will also serve as a pla orm and launch pad for scien sts, engineers and students to take their ideas from the lab, to working prototypes that can be commercialised.

The Agency for Science, Technology and Research’s (A*STAR) Ins tute of Microelectronics (IME) and Soitec, a France-based world leader in designing and manufac-turing innova ve semiconductor materials, recently an-nounced the launch of a joint programme to develop and integrate a new layer transfer process within advanced wafer level mul -chip packaging techniques.

Based on the combina on of IME’s Fan-Out Wafer Level Packaging (FOWLP) and 2.5D Through Silicon Interposer (TSI) technologies with Soitec’s Smart Cut technology, the new cost-compe ve process off ers higher perfor-mance, energy effi ciency and increased product yield.

Advanced packaging is used in many of today’s systems on chip (SOCs), for servers and high-end mobile, indus-trial, and automo ve applica ons, and involves various approaches for combining semiconductor chips into packages, to reduce costs, improve power effi ciency, and provide effi cient heat dissipa on.

By 2022, the advanced packaging market segment is expected to triple to two million wafer starts for mid- to high-end applica ons, according to the Yole Develop-ment 2017 report for 3D TSV and 2.5D by 12” wafer starts.

The rising complexity of today’s chips, with growing numbers of smaller and smaller transistors and circuits requiring high I/O counts, is driving collabora ve inno-va on across the advanced packaging process commu-nity, focused on iden fying cost-eff ec ve solu ons for manufacturing and increased data bandwidth, to support hand-held, cloud and edge compu ng applica ons.

One of the standard processes in advanced packaging involves using a full silicon wafer for the layer transfer process, which can cost up to 3 cents/mm2.

Soitec will partner with IME over the next three years to evaluate the use of its Smart Cut technology on IME’s advanced packaging platforms, FOWLP and 2.5D TSI, with the objective to integrate a new layer transfer process as a key step in future generations of packaging techniques.

This new process targets improved performance, lower power consump on and reduced produc on costs, by elimina ng the need to consume a full silicon wafer. IME will also conduct tests to evaluate the reliability and ro-bustness of the newly developed process, which will help Soitec to determine its long-term viability.

Smart Cut technology makes use of both implanta on of light ions and wafer bonding to defi ne and transfer ultra-thin single-crystal layers from one substrate to another. It works like an atomic scalpel and allows ac ve

layers to be managed independently from the suppor ng mechanical substrate.

Key benefi ts include the crea on of mul ple, thin, nanometric-scale layers of virtually defect-free silicon by u lising low temperature bond and split techniques. These layers are then placed on top of ac ve transistor circuitry. The thickness of the transferred layer can be determined with a high degree of precision by adjus ng the implanta on energy and process engineering. Tran-sistors can then be completed using etch and deposi on processes. Moreover, as the surface of the silicon wafer is repolished a er each layer transfer opera on, the substrate can be reused many mes.

As a leading research ins tute, IME brings together the global semiconductor supply chain, including fabless companies, foundries, OSATs, EDA suppliers, equip-ment manufacturers, and materials developers, to demonstrate advanced packaging solu ons for mobile, data-centre, high-performance compu ng, 5G, IoT and automo ve applica ons.

Through this collabora on with Soitec, IME will provide advanced packaging exper se in architecture defi ni on, modelling, design, process-integra on, reliability-assess-ment and failure analysis.

IME will execute the advanced packaging development in its fully func onal, 300 mm wafer level packaging, 2.5D/3DIC pilot line. IME’s end-to-end process capabili- es and know-how in advanced FOWLP and 2.5D TSI will

shorten development cycles and demonstrate cost-eff ec- ve packaging solu ons using Smart Cut technology.

During the joint programme, Soitec will contribute sig-nifi cant tool me, R&D personnel, and dedicated space in its clean room at its Pasir Ris fabrica on facility in Singapore.

“Advanced packaging con nues to be a bright spot in the high-value semiconductor market. We are excited to partner Soitec to develop packaging solu ons that will contribute to the dynamic growth of this high-poten al segment in Singapore and worldwide”, said Professor Dim-Lee Kwong, Covering Execu ve Director, IME.

“Soitec and IME believe Smart Cut technology will deliver breakthrough results, revolu onising 2.5D/3D layer transfer process fl ow”, said Mr Christophe Maleville, Soitec’s Chief Technology Offi cer.

“This strategic collabora on will not only develop a new Smart Cut applica on serving new genera ons of ad-vanced packaging, but also open a brand new market for Soitec, beyond tradi onal engineered substrate manu-facturing”, he added.

Nanyang Technological University, Singapore (NTU Singapore) and the French Alterna ve Energies and Atomic Energy Commission (CEA) have launched a joint research centre to develop innova ve, energy-effi cient solu ons for the recycling of, and recovery of resources from, electrical and electronic waste (e-waste).

The new centre, named NTU Singapore-CEA Alliance for Research in Circular Economy (NTU-SCARCE), will address the recycling of, and recovery of materials from, common e-waste such as discarded lithium-ion ba eries and printed circuit boards.

This is CEA’s fi rst research centre outside of France. It will look at formula ng advanced e-waste separa on and extrac on techniques that are more eco-friendly and energy-effi cient than current methods.

The Na onal Environment Agency (NEA) of Singapore is suppor ng the NTU-CEA joint research centre under the agency’s Closing the Waste Loop (CTWL) Research and Development (R&D) Ini a ve. Together, the three organisa ons are contribu ng SGD 20 million to this collabora on.

The research centre was unveiled recently by Singapore’s Senior Minister of State for the Environment and Water Resources, Dr Amy Khor. It will support Singapore’s drive towards becoming a Zero Waste na on, by fi nding ways to reduce consump on of materials, and reusing and recycling them to give them a second lease of life.

With a strong focus on promo ng sustainable industry processes, the joint centre’s aims are also in line with NTU’s focus in sustainability research.

NTU President Professor Subra Suresh, said, “This joint research centre will grapple with one of the increasingly important issues in recycling, as the world con nues to produce more electronic devices and e-waste. It will study new methods and technologies to process and recover precious materials from e-waste, while minimising environmental impact. This is also one of the core tenets of the NTU Smart Campus ini a ve which aims to develop technologically advanced solu ons for a sustainable future”.

CEA Deputy Chairman, Dr Laurence Pike y, said, “The CEA has been collabora ng with NTU, since 2012, on materials science, and the crea on of the joint NTU-CEA laboratory, our fi rst one to be implemented abroad, is a new decisive step in that way. More than 15 CEA researchers will spend extended periods in Singapore to strengthen this collabora on. This will make the most of CEA’s world-renowned exper se and technologies in materials recycling and waste management.

“In collabora on with NTU, we will examine solu ons for recycling ba eries and solar panels, and for the

treatment of electronic waste, where our R&D and innova on will be translated into industrial processes for ge ng high value-added products”, he added.

CTWL encourages collabora ons among ins tutes of higher learning, research ins tutes and private sector partners, to develop technologies and solu ons to tackle the challenges posed by increasing waste genera on, scarcity of resources and land constraints for waste management.

Mr Tan Meng Dui, Chief Execu ve Offi cer, NEA, said, “NEA is making steady and heavy investments in R&D ini a ves to address our waste management challenges, and to be er posi on Singapore for a more resource-effi cient and sustainable future. A key thrust of NEA’s technology masterplan is waste-to-resource R&D ini a ves which are aligned to our circular economy approach to move Singapore closer to its vision of a

Singapore’s Senior Minister of State for the Environment and Water Resources, Dr Amy Khor, launches the new NTU-SCARCE research centre which will develop innovative, energy-efficient solutions for the recycling of, and recovery of resources from, e-waste.

NTU President Prof Subra Suresh and Dr Amy Khor listening to a presentation by NTU-SCARCE Co-Directors, Prof Madhavi Srinivasan and Dr Jean-Christophe P Gabriel, on some of the advanced recycling technologies.

Zero Waste na on. We are delighted with this joint partnership with NTU Singapore and CEA France, in the form of SCARCE. The focus on e-waste is apt, given the pervasiveness of digital technologies, and addresses both important resource recovery and public health needs”.

Maximising the recovery of precious materials E-waste contains heavy metals that are both valuable and hazardous, and they must be properly managed and disposed of. The proper recycling of e-waste will not only protect human health and the environment, but also help to conserve resources since some of the materials are recovered.

NTU-SCARCE has four research thrusts that seek to achieve the following:• Recycling and recovering of materials from lithium-ion

ba eries.• Recycling and recovering of materials from silicon-based

solar panels.• Recycling and recovering of materials from printed circuit

boards in discarded e-waste.• Detoxifying plas c parts in e-waste.

For example, the joint lab will look into developing eco-friendly methods to recycle lithium ion ba eries, and extract up to 75% of metals such as cobalt, nickel, lithium and manganese. These materials can be re-used to produce new lithium ion ba eries.

One of the solu ons involves using ‘green chemistry’, a method that focuses on using chemical processes and earth-friendly products that minimise the use and genera on of hazardous substances.

NTU Professor Madhavi Srinivasan, Centre Co-Director, said, “In Singapore, about 60,000 t of e-waste, or 11 kg of e-waste per person, are generated each year. This lab will support the na on’s mission to fi nd new ways to recycle e-waste in a sustainable and eco-friendly manner while, at the same me, extract materials that can be used again”.

Discarded printed circuit boards are important e-waste products. These are thin copper-plated or etched circuit boards on which integrated chips and other electronic components are mounted.

These boards o en consist of metals such as copper, aluminium, gold and silver, as well as valuable organics and ceramics, which are o en lost during incinera on.

Current industrial recycling processes emit harmful pollutants and/or liquid waste that require costly treatment processes, so that they can be safely released into the environment.

Researchers will develop novel methods to separate and recover as much organics and ceramics as possible, for a variety of applica ons.

Centre Co-Director, Dr Jean-Christophe P Gabriel, said, “Closing the materials loop is a key challenge to enabling a sustainable environment. Electronic waste recycling concentrates many of the issues that must be solved and is the perfect testbed for achieving that aim.

Together with my colleagues in CEA, we are thrilled by this opportunity to work in synergy with our Singapore partners”.

Using the same principles as those used for recovering precious materials and reducing environmental harm, the lab will also fi nd sustainable solu ons to process solar panel e-waste and toxic plas c materials.

Researchers will explore ways to extract silicon and metals from solar panels, which could help reduce the costs to produce new panels. They will also develop a systema c approach to safely sort, detoxify and recycle hazardous plas c materials from e-wastes.

The agreement to set up the research centre on NTU’s campus was formalised last year, to mark Singapore’s strong es with France and France-Singapore Year of Innova on 2018.

INDUSTRY NEWS


Hypertherm, a US-based manufacturer of industrial cu ng systems and so ware, is introducing three new torch sleeves for XPR plasma cu ng torches and lead sets. The sleeves allow the torch and lead sets to remain axially fi xed while the torch holding device rotates 360° in either a clockwise or counter-clockwise direc on. This capability greatly enhances torch lead life in high-fl ex applica ons.

The new sleeves, available in short, medium, and extended lengths, are ideal for bevel or 3D/robo c cu ng applica ons when using either an XPR170 or XPR300 X-Defi ni on Plasma system. The sleeves include several engineering advances. An outside diameter of 76 mm allows for an increased wall thickness and eliminates compression caused by clamping. Pre-sealed, high precision bearings reduce axial play by 90%, and radial play by 81%. This keeps out dirt and other par culates associated with plasma cu ng and greatly extends the life of the sleeve and lead system.

When used with Hypertherm’s specialised robo c/bevel lead sets, the rota onal sleeve will aff ord customers a robust industrial solu on in applica ons requiring frequent rota onal fl exing, when cu ng with an XPR170 and XPR300. A combina on of engineering advances and refi ned high defi ni on plasma processes help X-Defi ni on class plasma deliver high plasma cut quality on mild steel, stainless steel, and aluminum. Laboratory tes ng shows ISO-9013 Range 2 cut quality on thin mild steel and extended ISO Range 3 cuts on thicker metals.

Both X-Defi ni on systems contain patent-pending processes like Vented Water Injec on (VWI), plasma dampening, and Cool Nozzle technologies for squarer cut edges, less angularity, and good surface fi nish on non-ferrous metals like aluminum and on stainless steel.

At the same me, the systems cut faster and use power more effi ciently than earlier Hypertherm systems like the HyPerformance HPR260XD.

Meanwhile, Hypertherm is shipping consumable kits for its XPR X-Defi ni on Plasma systems. These new consumable starter kits are available with or without a torch, for mild steel and non-ferrous cu ng applica ons. The kits include a variety of consumables to allow for cu ng at diff erent amperages, using all of the gas process types supported by the XPR170 and XPR300 systems.

The consumables contain several patent-pending technologies to improve consumable life and cut quality. Examples include Cool Nozzle, and Arc Response Technology which protects consumables from the nega ve impact of ramp down errors, a regular occurrence in real-life cu ng. By reducing the impact of ramp down errors, XPR consumables can last up to three mes longer than those for older genera on systems.

In addi on, XPR consumables are designed with ease of use in mind. An EasyConnect feature allows operators to quickly plug the torch lead into the torch connect console without the use of tools, while a patent-pending QuickLock electrode delivers easy quarter turn ghtening to further reduce setup me. Another new design feature is a quick change torch that enables an operator to rapidly change torches with just one hand.

Hypertherm designs and manufactures industrial cu ng products for use in a variety of industries such as shipbuilding, manufacturing, and automo ve repair. Its product line includes cu ng systems, in addi on to CNC mo on and height controls, CAM nes ng so ware, robo c so ware and consumables.

Whether tradi onal or new manufacturing processes are involved, none of the available technologies makes it possible to produce component surface fi nishes of the required quality. Process steps such as deburring, rounding and cleaning, as well as targeted func onal or decora ve surface fi nishing, are thus indispensable.

Solu ons for the reliable and economical execu on of these tasks will be presented at DeburringEXPO 2019, the 3rd Leading Trade Fair for Deburring Technology and Precision Surface Finishing, which will be held at the Karl-sruhe Exhibi on Centre, Germany, from 8 to 10 October 2019.

Parts manufacturing is currently faced with new tasks in numerous areas. Due to more and more complex geometries and fi ner structures, the requirements for machined, formed, primary formed, forged, sintered and moulded workpieces are ge ng stricter, as are the requirements for deburring and surface fi nishing.

The technical cleanliness of components is an essen al quality criterion in many industry sectors such as the automobile and automo ve supplier industries, aero-space and avia on, machinery manufacturing, medical engineering, metrology, precision engineering, sensor technology and drive technology, as well as in the fi eld of electromobility.

“Reliable deburring, during which extremely fi ne burrs and fl ash must also be removed, depending on the degree of required cleanliness, is a fundamental pre-requisite for complying with cleanliness specifi ca ons”, explained Mr Hartmut Herdin, Managing Director, fairX-perts GmbH & Co KG, promoters of DeburringEXPO.

Furthermore, in some cases, surfaces are required, which minimise fric on, wear and noise, and which make it possible to enhance performance and extend service life. Downstream processes such as joining, sealing, coa ng and assembly also necessitate burr-free and, in some cases, rounded edges, for various reasons. In the fi eld of sheet metal processing, deburring minimises the risk of injury due to sharp edges and reduces tooling wear for edging and straightening machines. On the other hand, good deburring and well-defi ned edge rounding make it possible to enhance pain ng quality at the edges.

“Relying solely on experience gained with previously used processes for these tasks can quickly lead to a compe ve disadvantage. Benchmarking is thus advis-able, which focuses central a en on on searching for the most eff ec ve, reliable and economical technologies”, Mr Herdin added.

Companies are also being confronted with new tasks in the area of surface fi nishing, which result from innova- ve produc on processes such as addi ve manufacturing

(AM). The removal of residual powder and suppor ng

structures, as well as the rough and porous surfaces produced by these processes, are challenging.

Cross-industry and cross-technology coverageThe above-men oned subjects and many others, as well, will be explored at DeburringEXPO 2019.

As at end-March 2019, a total of 125 exhibitors from 11 countries, including many market and technology lead-ers, have already booked exhibi on space.

The exhibi on por olio covers products, systems, processes and services, for deburring, the produc on of precision surface fi nishes and cleaning a er deburring, as well as measuring and test technology, in nearly all industry sectors. The exhibi on will also feature analysis systems for quality control and quality assurance of com-ponents made of a wide range of materials.

With its comprehensive spectrum, DeburringEXPO not only covers the en re process sequence for deburring and the produc on of precision surface fi nishes, it also iden fi es trends and imparts prac cal as well as theoret-ical knowledge.

Bilingual expert forum A three-day expert forum, with simultaneous interpre-ta on (German to English and English to German), has been integrated into DeburringEXPO 2019.

THE SINGAPORE ENGINEERApril 2019

Keysight Technologies Inc, a leading technology company recently released the results of a survey sponsored by Ixia, a Keysight Business, on ‘The State of Cloud Monitor-ing’. The report highlights the security and monitoring challenges faced by enterprise IT staff responsible for managing public and private cloud deployments.

The survey was conducted by Dimensional Research and polled 338 IT professionals at organisa ons from a range of sizes and industries globally. The results revealed that companies have low visibility into their public cloud environments, and the tools and data supplied by cloud providers are insuffi cient.

Lack of visibility can result in a variety of problems including the inability to track or diagnose applica on performance issues, inability to monitor and deliver against service-level agreements, and delays in detec ng and resolving security vulnerabili es and exploits.

Nearly all respondents (99%) iden fi ed a direct link between comprehensive network visibility and business value. The results confi rm that IT professionals see a di-rect connec on between access to packet data and their ability to maintain cloud security and performance.• 87% of respondents expressed fears that a lack of cloud

visibility is obscuring security threats to their organisa on.• 95% of respondents said visibility problems had led

them to experience an applica on or network perfor-mance issue.

• 38% cited insuffi cient visibility as a key factor in appli-ca on outages, and 31% in network outages.

“This survey makes it clear that those responsible for hybrid IT environments are concerned about their inability to fully see and react to what is happening in their networks, especially as business-cri cal applica ons migrate to a virtualised infrastructure. This lack of visibility can result in poor applica on performance, customer data loss, and undetected security threats, all of which can have serious consequences to an organisa- ons’ overall business success”, said

Recep Ozdag, General Manager and Vice President, Product Management in Keysight’s Ixia Solu ons Group.

Benefi ts of visibility solu ons Ninety-nine percent of respondents stated that comprehensive visibility has

direct value to their organisa ons, with the top three benefi ts being the ability to:• Monitor and ensure applica on performance (60%)• Enable threat iden fi ca on (59%)• Iden fy security ‘indicators of compromise’ (57%)

Comparison between the monitoring of clouds and tradi onal data centresThe survey focused on challenges faced when monitoring public and private clouds, as well as on-premises data cen-tres. Data revealed that, in the opinion of IT professionals, cloud providers are not providing the level of visibility they need. In par cular, they indicated the following:• Public cloud environments are diffi cult to monitor. Less

than 20% of IT professionals reported they had com-plete, mely access to data packets in public clouds. In private clouds, the situa on is be er, with 55% report-ing adequate access. In on-premises data centres, 82% have the visibility they need.

• Packet-level visibility is cri cal for monitoring. Eighty-six percent of respondents stated visibility was import-ant for network and applica on performance monitor-ing, and 93% stated it was valuable for security.

The survey also revealed that visibility is cri cal for moni-toring cloud performance, as well as valida ng applica on performance prior to cloud deployment. In par cular:

• Predic ng performance is a key challenge. Eighty-seven percent of cloud users fi nd it diffi cult to predict appli-ca on performance in the cloud.

Q: Why did you choose to pursue a career in Industrial Engineering? A: Industrial Engineering / Process Engineering is my fi eld of interest. I am pursuing it to gain knowledge and become a good solu ons provider.

Q: When did you develop the interest to study engi-neering? A: When I was young, I used to play with broken prod-ucts and tried opening them to see what is inside. I was always fascinated to do working models, as part of academic projects in secondary school. Later, I realised that this is what I would love to do, that is, I wanted to learn how things work. Hence, I took up Mechanical Engineering.

Q: What is the poten al today for manufacturing and, in par cular, for addi ve manufacturing? A: Manufacturing is evergreen. New manufacturing methods have come up, as product requirements be-come more dynamic and complex. This is especially so in addi ve manufacturing which has seen greater growth in recent years. I foresee that addi ve manufacturing would be used for, at least, 30% of the products we see around us, mainly because of its current ability to produce complex products with ease. Previously, such complex products were very expensive to produce or it was not possible to produce them. Addi ve manufactur-ing can help sectors such as healthcare, automo ve and aerospace, as it cuts down produc on cost and shortens the me required.

Q: How do you see yourself making an impact in this fi eld? A: I wish to work on addi ve manufacturing process development and on materials that can make it more aff ordable.

Q: What is the most fulfi lling aspect of your job? A: Jabil allows me to test my ideas and crea vity, and in a very short me in the company, I was able to develop a product which I conceptualised and designed. At Jabil, employees are valued and encouraged to develop their own ideas into prototypes.

My small project involved an automo ve part called a ‘diff eren al’. This part is used in the rear sec on of an

automobile. The part is usually complicated, but using 3D prin ng technology, we were able to create prototypes in a short period, and it became easier to fi nd solu ons to problems rela ng to the part.

Jabil has given me a wealth of resources and knowledge to tap into, as well as specialist training to expand my understanding of the fi eld. I have the freedom to create what I have in mind and promote my ideas.

Q: What is the main misconcep on about engineers?A: Engineers are commonly stereotyped as being non-crea ve, but they are actually solu on providers. Crea vity is defi nitely an element involved in coming up with solu ons. Engineers like to solve real problems, and constantly challenge themselves.

Q: Would you encourage young people to choose a career in STEM? A: Yes, very strongly, since STEM careers contribute sig-nifi cantly to society.

Nanyang Technological University, Singapore (NTU Singa-pore) and Volvo Buses launched the world’s fi rst full size, autonomous electric bus recently. The single-deck, Volvo Electric bus is 12 m long and has a full capacity of close to 80 passengers.

This is a key milestone in NTU and Volvo’s development programme, under the university’s partnership with the Land Transport Authority (LTA), which was announced in October 2016, to develop and conduct autonomous vehicle bus trials for fi xed route and scheduled services.

The Volvo 7900 Electric bus is equipped with numerous sensors and naviga on controls, managed by a compre-hensive ar fi cial intelligence (AI) system.

Ensuring maximum safety and reliability, the AI system is also protected with industry-leading cybersecurity mea-sures to prevent unwanted cyber intrusions.

The Volvo bus is the fi rst of two buses to undergo rigor-ous tes ng at the Centre of Excellence for Tes ng and Research of Autonomous vehicles at NTU (CETRAN).

Jointly set up by NTU, LTA and JTC, CETRAN is a centre dedicated to research and tes ng of autonomous vehi-cles. It replicates various elements of Singapore’s urban road condi ons, such as traffi c signals, mul ple bus stops and pedestrian crossings, and tropical condi ons such as heavy rain and par ally fl ooded roads. Operated by NTU scien sts, CETRAN is located on the NTU Smart Campus in Jurong Innova on District.

Plans are in place to test the bus at NTU and to subse-quently extend the route beyond the NTU campus.

NTU President Professor Subra Suresh, said, “This fully autonomous electric bus will play a role in shaping the future of public transporta on that is safe, effi cient, reliable and comfortable for all commuters. It will soon be tested on the NTU Smart Campus which has been home to a number of innova ons, as a living testbed for technologies that impact the human condi on and the quality of life”.

“This research project not only involves cu ng-edge science, technology and AI, but is also an excellent exam-ple of close partnership among academia, industry and government agencies, in transla ng basic research into products and services for the benefi t of Singapore and beyond. And we have a top team of local and interna- onal partners in this mul -disciplinary collabora on”,

he added.

The electric bus has 36 seats and is characterised by

quiet opera on with zero emissions. It also requires 80% less energy than an equivalent-sized diesel bus.

This is Volvo’s fi rst fully autonomous, electric bus in pub-lic transporta on anywhere in the world. For this trial, involving a full size single-deck bus, Volvo chose NTU Singapore as its global partner.

Mr Håkan Agnevall, President, Volvo Buses, said, “We are very proud to be showcasing our electric bus featuring autonomous driving technology. It represents a key mile-stone for the industry and is an important step towards our vision for a cleaner, safer and smarter city. The journey towards full autonomy is undoubtedly a complex one, and our valued partnership with the NTU and LTA is cri cal in realising this vision, as is our commitment to applying a safety-fi rst approach”.

The NTU and Volvo partnership is part of the collab-ora on between NTU and LTA, under NTU’s living lab pla orm. The pla orm assesses technology maturity and roadworthiness, and includes the cer fi ca on of technol-ogies for deployment on public roads.

Mr Lam Wee Shann, Chief Innova on and Technology Offi cer, LTA, said, “The launch of the autonomous bus for on-road trials marks an important milestone in the joint project between LTA and NTU Singapore, to develop au-tonomous buses for fi xed routes and scheduled services. It is in line with Singapore’s vision of deploying autono-mous vehicles to improve accessibility and connec vity for commuters. We will con nue to work closely with NTU to facilitate the safe and robust tes ng of the auton-omous vehicles”.

Protec on of sensors and technology through cybersecurity measuresThe bus comes with a Volvo Autonomous Research Plat-form so ware that is connected to key controls such as its naviga on system, as well as mul ple sensors.

This includes light detec on and ranging sensors (LI-DARS), stereo-vision cameras that capture images in 3D, and an advanced global naviga on satellite system that uses real- me kinema cs. This is like any global posi on-ing system (GPS), but uses mul ple data sources to give loca on accuracy of up to 1 cm.

The system is also hooked up to an ‘iner al management unit’ which acts like a two-in-one gyroscope and acceler-ometer, measuring the lateral and angular rate of the bus. This will improve its naviga on when going over uneven terrain and around sharp bends, ensuring a smoother ride.

These sensors and GPS pla orms will be managed by a comprehensive AI system that was developed by NTU researchers. It not only operates the various sensors and GPS systems on the bus, but also enables it to navigate autonomously through dense traffi c and tropical weather condi ons.

The AI system is protected with industry-leading cyber-security and fi rewall measures, to prevent unwanted intrusions and ensure maximum safety and reliability.

Mul -industry collabora onAs part of the public trials, Singapore’s public transport operator, SMRT, will play a key role in determining the roadworthiness of autonomous vehicles on public roads.

While plans are in place to test the fi rst bus on the NTU campus, a second, autonomous, 12 m Volvo 7900 Electric bus will undergo tests at a bus depot managed by SMRT.

The depot will provide a real-world environment to assess the vehicle’s ability to autonomously navigate into vehicle washing bays and park safely at charging areas.

Mr Tan Kian Heong, Managing Director, Buses & Roads Services and Senior Vice President, Human Resources, SMRT, said, “SMRT is pleased to support the research and development of these eco-friendly autonomous electric buses. As part of the Autonomous Electric Bus trial, we will leverage on our exper se in opera ons and maintenance of buses, and work closely with our part-ners to test the command and control system required to operate a fl eet of autonomous vehicles. This will help us to stay future-ready with the latest urban mobility solu ons, to enhance the accessibility and connec vity of our public transport network”.

Another partner, ABB, a pioneering technology leader in digital industries and world leader in fast-charging infrastructure for electric vehicles, will develop a smart fast-charging solu on. Based on the OppCharge concept, ABB’s HVC 300P fast charge system is ideally suited for autonomous charging in bus depots as well as in running traffi c.

Off ering a charge power of 300 kW via a pantograph mounted on the infrastructure, the fast chargers will recharge a ba ery in just three to six minutes. This will enable charging during the layover mes at the end of the bus route, without impac ng normal opera ons.

Mr Tarak Mehta, President of Electrifi ca on Products Division, ABB, said, “ABB is commi ed to pioneering technological innova ons for a sustainable future. We are extremely excited to collaborate on such a land-mark project which marks a posi ve step toward the electrifi ca on of public transport across the region and beyond”.

Specially equipped NVH chassis dynamometer for vehicles with a combus on engine, a hybrid drive, or an electric drive, and for all-wheel, front-wheel and rear-wheel drivetrains.

Vehicle acous cs is steadily gaining trac on as a quality criterion in today’s cars. When a vehicle is in mo on, au-dible or percep ble vibra ons emana ng from individual components can cause annoying automo ve noise, con-veyed by the vehicle’s structure and rendered as airborne sound. Acous cs experts refer to this phenomenon as NVH (noise, vibra on, harshness). Minimising noise with NVH analyses is a fi xture of automo ve engineering.

‘The increasing shortening of development cycles re-quires an ideal integra on of acous c op misa on into exis ng development processes”, says Jörg Ve er, Senior Manager, New Calibra on Services & Products at Bosch Engineering, the Robert Bosch GmbH subsidiary spe-cialising in development services for vehicle and engine manufacturers.

With the new acous cs test centre in Absta , Germany, the company is se ng the stage for an effi cient devel-opment process to improve NVH. It will enable develop-ment mes to be reduced s ll further, while enhancing vehicle acous cs.

Complete acous cs engineering developmentAcous cs is a major issue in automo ve engineering. Firstly, government regula ons for vehicle registra on set out lim-its for external noise levels. Secondly, car buyers and owners expect less vibra on and noise and a smoother, quieter ride. New electric and hybrid drives also present consider-able and o en very specifi c challenges for acous cs experts seeking to improve NVH. Acous cs has to be included early on in the development process, when new models are s ll on the drawing board.

Bosch Engineering supports automakers’ eff orts to im-prove NVH, with a holis c engineering approach focused on op mising the vehicle.

“In acous cs analysis, we take advantage of the syner-gies resul ng from the close collabora on within Bosch Engineering and with the Bosch Group’s acous cal engi-neers”, says Jörg Ve er.

The company off ers customers a comprehensive service package spanning the en re product development chain for a new vehicle. In addi on to providing advice in the design phase and support in the development phase, it also helps customers to con nue improving their vehi-cles’ NVH behaviour.

Pu ng vehicle acous cs to the testEngineers o en test-drive cars on public roads or private test tracks to inves gate their acous cs. The problem with open-road tests is that external factors such as ambient noise, weather condi ons or the driver’s profi le may skew the measured results. This is why test series are o en long and tedious, with results that are hardly reproducible.

Bosch Engineering has created an ideal environment for assessing vehicles’ NVH performance in its acous cs test centre in Absta . With a sound-proof hemi-anechoic chamber isolated from the outside world, it provides a more effi cient means of tes ng and comparing new or modifi ed components and calibra ons under uniform condi ons, and provides feedback on their impact on the overall vehicle. This reduces the cost and me involved in engineering the acous cs of new cars and op mising the acous cs of legacy vehicles.

The aim is to reduce automo ve noise, vibra on and harshness.

“In our test centre, we can quickly detect noise sources that impair driving comfort and develop countermea-sures together with our customers”, notes Jörg Ve er.

Tailor-made and reproducible, the development centre’s measurement, analysis and evalua on procedures serve to rapidly assess and op mise acous cal phenomena.

Features of the acous cs test centreThe centrepiece of Bosch Engineering’s acous cs test centre is a specially equipped chassis dynamometer. It is suitable for vehicles with a combus on engine, a hybrid drive, or an electric drive, and for all-wheel, front-wheel and rear-wheel drivetrains. Four independently controlla-ble rollers deliver 150 kW each, for speeds ranging up to 250 km/h. They can simulate various wheel torques, for example, that of a cornering car, and wheel loads. A well-insulated test cabin and silent rollers reduce back-ground noise to a minimum, so that engineers can mea-sure even very low sound pressure levels. This is a great compe ve advantage, especially for tes ng electric ve-hicles. Without a combus on engine to mask automo ve noise, the acous cs of powertrain peripherals are far more percep ble. The test bench design even includes specifi c monitoring func ons for future hydrogen vehicles.

The lab, sound studio and chassis dynamometer are in separate rooms. The lab is equipped with precision instrumenta on for measuring vibra on and sound pressure levels and conduc ng modal analyses to break down dynamic NVH behaviour. The sound studio features high-tech equipment including headphones for binaural reproduc on and a 13-speaker array for higher-order Ambisonics reproduc on. This setup enables engineers to compare diverse components’ acous c behaviour in the virtual realm, without having to install them in the actual vehicle. They can also switch between two NVH scenarios, at the push of a bu on, for A/B comparisons.

Upstream from the tes ng area is an assembly hall. It serves as a staging area to prepare vehicles for tests. With its capacity for precondi oning up to 10 cars simultaneously, it provides an effi cient means of execut-ing even extensive sets of measurements and achieving reproducible results

In a room with low hemi-refl ec on, so-called free-fi eld condi ons prevail under which, for example, the sound power of an acous c bubble spectrometer (ABS) can be determined using a microphone array.

With the ar fi cial head, various interior noises, such as engine noise, can be recorded binaurally in the vehicle.

In the sound studio, various components, such as windscreen wipers or window regulator motors, can be quickly compared with diff erent calibra on se ngs. Results from computer simula ons can also be made audible.

ARTIFICIAL INTELLIGENCE


By 2021, Ar fi cial Intelligence (AI) will allow the rate of innova on and employee produc vity improvements in Singapore to nearly double (X1.9 mes and X1.7 mes, respec vely), according to business leaders in

Singapore. This is revealed in a study by Microso and IDC Asia/Pacifi c, tled ‘Future Ready Business: Assessing Asia Pacifi c’s Growth Poten al Through AI’. A total of 1,605 business leaders and 1,585 workers (including 104 business leaders and 102 workers in Singapore) par cipated in this study. Fi een Asia Pacifi c markets were involved - Australia, China, Hong Kong, Indonesia, India, Japan, Korea, Malaysia, New Zealand, Philippines, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam. The industries covered include agriculture, automo ve,

educa on, fi nancial services, government, healthcare, manufacturing, retail, services and telco/media.While more than 80% of business leaders polled agreed that AI is instrumental to their organisa on’s compe veness, only 59% of organisa ons in Singapore have embarked on their AI journeys. Those organisa ons that have adopted AI expect it to increase their compe veness 1.7 mes, by 2021.

“Today, every company is a so ware company, and increasingly, every interac on is digital. To be successful in this new world, organisa ons need to be a fast adopter of best-in-class technology; and secondly, they need to build their own unique digital capabili es”, said Mr Kevin Wo, Managing Director, Microso Singapore.

“AI is the defi ning technology of our me, that signifi cantly accelerates business transforma on, enables innova on, boosts employee produc vity, and ensures further growth. Economies and businesses that have yet to embark on their AI journey run a real risk of missing out on the compe ve benefi ts that are enjoyed by leaders”, he added.

The reasons for adop ng AIFor the organisa ons that have implemented AI ini a ves, the top fi ve business drivers for adop ng the technology are, in order of priority:• Be er customer engagement (32% of respondents

named it as the number one driver)

AI EXPECTED TO NEARLY DOUBLE THE RATE OF INNOVATION IN SINGAPORE

Despite clear benefi ts, there are barriers to its widespread adop on.

• Higher compe veness (19%)• Accelerated innova on (16%)• Higher margins (15%)• More produc ve employees (6%)

Mr Victor Lim, Vice President, Consul ng Opera ons, IDC Asia/Pacifi c, said, “Last year, organisa ons that have adopted AI saw tangible improvements in those areas, in the range of 16% to 26%. They forecast further improvements of at least 1.6 mes in the three-year horizon, with the biggest jump expected in accelerated innova on”.

The need to build on infrastructure

The study evaluated six dimensions cri cal to ensuring the success of a na on’s AI journey. It uncovered that Singapore needs to build upon its infrastructure in order to accelerate its AI journey.

“Singapore is not ready yet for AI. To succeed in the AI race, markets in the region need to substan ally improve their readiness. Organisa ons’ leadership should make AI a core part of their strategy and develop a learning agility culture. They have to con nuously invest in this transforma ve technology for the long-term success, some mes without immediate returns. There is an urgent need for talents and tools to develop, deploy and monitor AI models, along with the availability of a robust data estate with the adequate governance”, Mr Lim added.

Business leaders who are adopting AI face three top challenges - a lack of thought leadership and leadership commitment to invest in AI; a lack of tools and infrastructure to develop actionable insights; and a lack of skills, resources and continuous learning programmes.

The study showed that to move ahead on their AI journeys, businesses have to create the right organisa onal culture. More than half of the business leaders and workers surveyed believe that cultural traits that support AI journeys, such as risk-taking, proac ve innova on, as well as cross-func on partnerships among teams, are not pervasive today.

“Business leaders must now embrace a new culture, where innova on and con nuous learning are core components of the organisa onal culture. It sets the stage for agility, adaptability and growth”, said Mr Wo.

Skills challenges for an AI-enabled workforceThe study found that Singapore’s business leaders and workers hold positive viewpoints about AI’s impact on the future of jobs. The majority (62% of business leaders and 71% of workers) believe that AI will either help to do their existing jobs better or reduce repetitive tasks.

“When it comes to crea ng or replacing jobs, 29% of business leaders believe that AI will produce new jobs, whereas 9% feel that the technology will replace jobs. Interes ngly, workers are more op mis c, with only 4% expec ng AI to replace jobs, and 10% an cipa ng AI to create new ones”, said Mr Lim.

The study also found that workers are more willing to reskill than business leaders believe. Only 12% of workers felt that it was a challenge, while 20% of business leaders say it may be too diffi cult for workers to develop new skills.

“Microso ’s vision for AI is fi rst and foremost about people. AI technology cannot progress without them. This means that millions will need to transform

themselves into skilled workers as well as learners that an AI future needs”, said Mr Wo.

“It is heartening to see that 80% of businesses priori se skilling and reskilling of workers in the future. They plan to invest as much, or even more, in human capital, than in new technology. Even so, 75% of business leaders have yet to implement plans to help their employees to acquire the right skills, which is worrying in today’s context. They must have the urgency to support the fundamental shi in training workers for the future”, he added.

“The jobs of today will not be the jobs of tomorrow, and we have already seen demand for so ware engineering roles expand rapidly beyond just the tech sector. However, building an AI-ready workforce does not necessarily mean an acute need for technological skills”, Mr Wo con nued.

The top three future skills required by business leaders in Singapore include crea vity, digital skills and cri cal thinking. The demand for all three is higher than the exis ng supply.

The study also uncovered that business leaders value so skills more than workers expect. The biggest skills gaps iden fi ed were in:• Adaptability and con nuous learning (26-pt diff erence)• Crea vity (14-pt diff erence)• Digital skills (14-pt diff erence)

AI leadersThe study iden fi ed 6% of organisa ons which are AI leaders. These organisa ons have already incorporated AI into their core business strategy and nearly doubled their business benefi ts today as compared to other organisa ons.

BIOMEDICAL ENGINEERING


Today, one in eight Singaporeans is over 65 years old. By 2030, this will increase to one in four [1]. This dras c change in demographics comes with several challenges, including the risk of major health shocks, such as cancer and neurodegenera ve diseases, that increases with age [2]. The current trend also indicates that one in four Singaporeans will contract a chronic disease by the me they are 65 or older [3]. With a quarter of the popula on expected to be senior ci zens, a decade from now, there is an urgent need for more innova ons in preventa ve healthcare to keep the ageing popula on healthy.

The good news is that the solu on is hiding in plain sight - in our data. Electronic medical records, genomics and personal tech devices are capturing an ever-grow-ing number of data points that can give us insights into the lives of ageing ci zens. Analysing this unprec-edented resource could help lead researchers to new insights, through the discovery of previously unno ced rela onships and pa erns in the health of the popula- on. Smart devices, such as step trackers and heart rate

monitors, are capturing a plethora of data that could help further research in this fi eld. Advances in data capture, analy cs and ar fi cial intelligence could allow healthcare professionals to be er determine the causes of chronic illnesses, develop new drugs and enable preventa ve treatments [4]. However, analysing data on this massive scale requires substan al computa on-al power across a pla orm architecture that innately enables the discovery of rela onships amongst data from mul ple sources.

This is something which Memory-Driven Compu ng can provide. By having a huge common memory pool that integrates various processors in one system, Memo-ry-Driven Compu ng uses hyper-fast memory processing to analyse a large amount of data in a rela vely short amount of me, opening new possibili es for connec ng and u lising data in healthcare.

Improving the precision of modern medicineOne way of u lising data to advance healthcare is through precision medicine which is tailored to an indi-vidual pa ent’s needs, so that treatments can be more eff ec ve, and inaccurate diagnoses and unnecessary medica on can be avoided.

The key to precision medicine lies in a clearer under-standing of our gene c and genomic informa on. How-ever, our gene c uniqueness poses a challenge to clinical care. In fact, experts understand only less than 1% of the gene c variants in the popula on. Today, the complex process of be er understanding genomes, through manual pa ern recogni on and correla on, prevents real- me classifi ca on and diagnosis. As a result, health-care professionals are o en able to make only assump- ons about a pa ent’s health.

Hewle Packard Enterprise (HPE) is trying to change this through the use of Memory-Driven Compu ng. HPE is collabora ng with AI-driven, biotechnology start-up Jungla, to power a technology pla orm that con nuously integrates clinical knowledge with genomic and biophys-ical data to systema cally generate, evaluate, audit and share accurate research and tes ng results. A Memo-ry-Driven Compu ng architecture off ers an unprecedent-ed capacity to process data, signifi cantly reducing the risk of human error and drama cally shortening the me needed to obtain results - by up to 52 mes compared to tradi onal hardware.

Precision medicine could be a game-changer for coun-tries with ageing popula ons, such as Singapore [5]. It will become possible to iden fy people who are at high risk of contrac ng a chronic disease, analyse their genet-ic makeup, and prescribe the most eff ec ve medica on or treatment for them, ensuring they remain healthy into their golden years. That could soon become a reality.

DZNE is currently studying a popula on of 30,000 people over 30 years to fi nd answers for brain diseases like Alzheimer’s, with help from an HPE supercomputer. The fi ndings could improve the lives of the billion people who live with neurological disorders, worldwide. By using Memory-Driven Compu ng, we are further accelera ng this journey, by improving, for example, an RNA se-quence alignment process, by about 10 mes.

Keeping healthcare aff ordableBefore healthcare can start improving lives, it has to be aff ordable. Yet, medical costs con nue to infl ate, and in Singapore, medical infl a on is expected to hit 10% this year, which is 2% higher than the global average of 8% [6]. Against the backdrop of an ageing popula on

and the increased prevalence of chronic diseases, the country’s healthcare expenditure is expected to triple, by 2030, to SGD 44 billion [7].

Technology can help lower these rising costs. The use of high-performance compu ng (HPC) and Memory-Driven Compu ng could allow the simultaneous, rela onal pro-cessing of massive data sets to create computer models that can simulate the human body. This means that healthcare professionals could conduct real- me tests to evaluate the eff ect of a medical s mulus on a par cular individual - resul ng in far quicker, more accurate and less costly diagnoses.

Solving healthcare and other global challenges through Tech Impact 2030The applica ons of Memory-Driven Compu ng and HPC go beyond analysing gene c results. Memory-Driven Compu ng accelerates the analysis of data and has the ability to disrupt conven onal medical tes ng, and at scale. The poten al impact of that disrup on is unprece-dented, especially in the fi eld of crea ng digital twins of the human body. By running simula ons to study the ef-fects of par cular treatments on organs or even individ-ual cells, we could further advance precision medicine. Today, we are already seeing bold steps in that direc on - from digitally reconstruc ng and simula ng the mamma-lian brain to crea ng mul -scale 3D models of a human heart. The possibili es of pu ng such technologies to work are far-reaching.

Improving the speed and accuracy of medical research is just one of the global challenges that HPE is a emp ng to solve. As part of the company’s Tech Impact 2030 ini a- ve, HPE is working with the World Economic Forum to

bring together technology, industry and government part-ners to drive awareness of, and progress in overcoming, societal challenges in key industries including agriculture, healthcare, transporta on and manufacturing. A er all, technology’s true promise lies in the good we can do and the challenges we can overcome - together.

DATA CENTRES


Global Switch, a leading owner, operator and developer of large-scale, carrier and cloud-neutral data centres in Europe and Asia-Pacifi c, recently launched its Singapore Woodlands data centre, in partnership with China Telecom Global Limited, a wholly-owned subsidiary of China Telecom Corpora on Limited, and one of the world’s largest providers of integrated telecommunica on services, and Daily-Tech, a developer and operator of data centre infrastructure across China.

It is the second such facility under the strategic partnership between the three companies, and follows the launch of their Hong Kong data centre in late 2017.

Built at a cost of SGD 280 million, the new 25,000 m2 data centre is located in Woodlands. It is physically some distance away from the exis ng Global Switch Tai Seng data centre, making the facili es a rac ve to customers seeking a two-site data centre solu on. Services from the new data centre are now fully available and customers will benefi t from the resilient, mission-cri cal environment off ering mul ple connec vity op ons for scalable and fl exible solu ons and a full range of ICT services.

This Singapore Woodlands data centre, which incorporates some of the latest energy-effi cient technologies, is an example of an environmentally sustainable data centre. The building is designed with a Power Usage Effi ciency (PUE) of 1.34, making it one of the most power-effi cient data centres available to customers in Singapore. This PUE compares favourably with the target average PUE of 1.78 set by the Na onal Environment Agency (NEA) in Singapore. In addi on to its high energy effi ciency, the new data centre is targe ng a Leadership in Energy and Environmental Design (LEED) Gold ra ng and a BCA Green Mark Pla num ra ng.

Opera ng to Tier III+ standards, the Singapore Woodlands data centre services are powered by 30 MVA of u lity power supply capacity, coming from two separate incoming supplies, to ensure mul ple layers of redundancy. The facility is also secure, with a network opera ons centre staff ed 24x7x365, complete with round-the-clock security patrols, and backed by con nuous CCTV surveillance and a comprehensive intruder detec on system. The new data centre services have incorporated sophis cated building management systems, resul ng in a resilient environment backed by Global Switch’s Cri cal Environments Programme.

Customers will benefi t from a mul tude of connec vity op ons, including the ability to directly connect, on a low latency basis, to the Global Switch Singapore Tai Seng data centre. As an integral communica ons hub

in the Asia-Pacifi c region, the Singapore Tai Seng data centre hosts a diverse and network-dense interna onal telecommunica ons environment, including a number of submarine cable systems which land directly at the facility. Customers will be able to access this connec vity-rich environment which also includes the Singapore Internet Exchange (SGIX) as well as all the leading internet services companies, from ISPs and major content owners and distributors to web portals and online social media.

John Corcoran, CEO of Global Switch, said, “Global Switch Singapore Woodlands marks our 12th world-class, data centre and has increased our footprint to 4,000,000 2 (365,000 m2) of technical space. It represents another important milestone for Global Switch and we are delighted to have launched this new data centre with our strategic partners China Telecom Global and Daily-Tech - reinforcing our leadership in providing the best-in-class solu ons for customers’ seamless and successful business opera ons across the region”.

MANUFACTURING


Some of the challenges food and beverage (F&B) manu-facturers face today are:

• Strict Regula ons - Regula ons can be imposed by external agencies, government authori es, or regulatory boards within the F&B industry itself. F&B manufacturers and product handlers need to ensure that they comply with environmental legisla on, factory audits etc.

• Expansion and Globalisa on - Manufacturers face the challenge of standardising produc on, in terms of cost, produc vity and quality control, when manufacturing under diff erent circumstances or at diff erent loca ons, as their businesses grow.

• Popula on and Society - An ageing, more health-con-scious and diversifi ed popula on means changing F&B consump on pa erns.

• Environment-friendliness and Sustainability - Nu-merous drivers exist in this area, from adop on of eco-friendly materials to new packaging designs. Manufacturers are always in a constant drive to reduce wastage, to be cost-eff ec ve.

What can F&B manufacturers do in view of these chal-lenges?

Today’s F&B manufacturers need to run machines and produc on lines that are designed and confi gured to cope with the ever-increasing demand for product diversity. One key area where many manufacturers have been making improvements concerns changeover me. Modern produc on lines allow manufacturers to quickly and fl exibly integrate sequen al opera ons into an overall manufacturing system, ensuring that even small batch-sized produc on runs can be accomplished with minimum waste of me and resources.

Visualisa on and produc vity Manufacturers need to drive produc vity like never before. Directly linking produc on to retailer demand is a growing issue. As a result, pressure on line produc vity is increasing, meaning down me must be constantly reduced to avoid produc on disrup on and poten al penal es.

Manufacturers today want clear visualisa on of their en re produc on system. Managers need to have a view on everything on the factory fl oor, so that they can im-

mediately make adjustments and solve problems as they arise. Be it in deploying engineering support or perform-ing con nuous produc on analysis, enhanced visualisa- on is the basis for line improvement programmes.

Informa on management and verifi ca onEnsuring that a produc on facility runs at op mum capacity and quality levels requires a lot of informa on. Data must be gathered in real- me, from mul ple de-vices, onto one pla orm, and directly communicated to the manufacturer’s informa on network, thereby saving addi onal hardware costs and complexity.

For instance, there are controllers that deliver plant-wide monitoring and control capabili es, and in-built database func onality, to provide a secure, robust and easy-to-im-plement system.

These controllers allow manufacturers to inspect, mea-sure, store and analyse produc on data, and share it within the supply chain, where required. Automa c data collec on can be employed to achieve accurate and reli-able monitoring and recording. This means that detailed produc on informa on can be provided in the event of a recall being required, thereby minimising fi nancial losses and protec ng brand reputa on.

Data and informa on can also contribute to be er ener-gy management. It is vital for manufacturers to monitor and analyse where and when energy is used and, based on this informa on, make decisions such as reducing extract fan or conveyor speeds to ‘idle speed’, when produc on is halted for short periods of me.

Manufacturers need to ensure that they have automated energy monitoring solu ons in place. Solu ons should include sensors for electrical, airfl ow and temperature measurement, and provisions for all data to be shared with the line controller.

Quality inspec on and traceabilityThere are many facets of quality within the manufactur-ing environment. These relate to products, primary and secondary packaging, correct product/packaging com-bina on, and verifi ca on of codes such as date codes. A system that allows 100% in-line inspec on, to check all product parameters, is a vital part of reducing scrap and maintaining plant produc vity.

F&B INDUSTRY TURNS TO

TECHNOLOGY AS BUSINESS CHALLENGES MOUNT

Mr Swaminathan Vangal Ramamurthy

MANUFACTURING


Manufacturers today can achieve this through auto-ma on and robo cs technology. Specifi cally, they can deploy vision sensors and automated systems that can eff ec vely manage inspec on projects at much higher accuracies and speeds than what human workers can achieve.

Furthermore, F&B manufacturers must record and present, as well as share with the supply chain, produc- on traceability informa on. Automa on and robo cs

technologies adopt serialised numbers or unique codes, vision sensors and controllers, as well as RFID systems, to allow for the eff ec ve tracking of products and produc- on processes. Manufacturers can easily recall items if

required, which helps them to retain consumer trust and brand reputa on.

Robo c product handling and safety servicesRobots are playing an increasingly important role in the F&B sector. They provide safer, more fl exible, effi cient and hygienic solu ons in a number of diverse projects. A growing trend is for robots to be deployed on the factory fl oor, working eff ec vely and effi ciently right next to human workers.

Equipped with built-in integrated hardware and so -ware controls, as well as vision and safety capabili es, OMRON’s delta-type robots are a good example. These CE-compliant and USDA-cer fi ed robots also comply with hygiene requirements that are crucial for food manufacturers.

Automa on solu ons that encompass sensors, light cur-tains and switches through to controllers are also useful for further ensuring safety on the factory fl oor. In fact,

automa on and robo cs today not only raise produc vi-ty levels in the factory, they also help to maintain appro-priate safety levels in order to protect personnel.

F&B manufacturers need to ensure that automa on and robo c systems are fully tested and that ideas are validat-ed before actual deployment and implementa on. They need to ensure that when tes ng ideas, tests replicate, as closely as possible, actual condi ons in areas such as prod-uct handling, mo on control, vision and safety. When it comes to F&B, manufacturers must view all aspects of the produc on process and product handling, with stringent controls in place and zero room for compromise.

The Associa on of Aerospace Industries (Singa-pore), or AAIS, announced the forma on of the Singapore Unmanned Aircra Systems Commu-nity (Singapore UAS Community). Conceived with the support of the Civil Avia on Authority of Singapore (CAAS) and Enterprise Singapore, the community aims to represent and serve the interests of the emerging UAS sector in Singapore. This includes aerospace companies, technology start-ups, suppor ng solu on and service provid-ers, end-users and educa onal ins tu ons.

The announcement was made by Guest-of-Hon-our, Mr Baey Yam Keng, Senior Parliamentary Secretary, Ministry of Transport, at the opening of Rotorcra Asia 2019 and Unmanned Systems Asia 2019. To help connect UAS businesses to market opportuni es, AAIS also launched its inaugural Singapore UAS Directory 2019.

President of AAIS, Mr Philip Quek said, “The surge in public and private sector demand for UAS solu ons provides a glimpse of the market’s untapped poten- al. Building upon our strengths as an associa on,

we will engender the UAS Community, and together, play a role in suppor ng market development and access, sourcing of new technologies, development of standards and policy advocacy”.

Congratula ng AAIS on the launch of its UAS Community and the inaugural publica on of the Singapore UAS Directory, Mr Simon Lim, Execu ve Director for Manufacturing & Engineering, Enter-prise Singapore, said, “This brings together the in-dustry’s eff orts and resources, and will poten ally yield solu ons that can scale beyond our shores. Enterprise Singapore will collaborate with AAIS in understanding the needs of UAS businesses to be er support them in the development of new capabili es and innova ve solu ons, and access-ing global opportuni es”.

According to the Interna onal Civil Avia on Organisa on (ICAO), Unmanned Aircra Systems is a term referring to ‘aircra and the associated elements which are operated with no pilot on board’. This would also include what are com-monly known as ‘drones’ and ‘passenger drones’. Goldman Sachs Research has es mated a USD 100 billion market for UAS (excluding passenger drones) over fi ve years, from 2016 to 2020, with the fastest growth opportunity for commercial and civil applica ons.

VOLOCOPTER TO CONDUCT FLIGHT TESTS IN SINGAPOREVolocopter, a pioneer in urban air mobility, will be conduc ng inner urban fl ight tests in Singapore, later this year.

These fl ight tests are designed to validate and verify the ability of Volocopter’s eVTOL vehicles to operate in Singapore’s urban environment and will culminate in public demo fl ights.

Volocopters are said to be emissions-free, elec-trically powered aircra that take off and land ver cally. They resemble a helicopter in looks, but are based on drone technology and can fl y two people for just short of 30 km. The Volocopter is designed specifi cally for inner city missions. It is said to off er stable fl ights, with its ability to manoeuvre even when there is microturbulence around skyscrapers. At a fl ight height of 100 m, it cannot be heard over the typical background noise of a city.

METALWORKING


Today, a en on is being focused on not only the actual manu-facturing processes, but also on intermediate and downstream processes such as deburring and surface fi nishing, for the produc on of high-quality components. The produc on of precision parts is characterised by highly demanding specifi ca- ons with regard to tolerances

and surface quality.

On the one hand, this is tar-geted at obtaining burr-free components and workpieces with defi ned edges and fi llets or a surface fi nish which minimises fric on, wear and noise, and increases performance and service life. On the other hand, manufacturing steps for precise shaping are required as well, and in this respect, machin-ing and surface fi nishing are converging to an ever greater extent. In order to master these challenges, innova ve, advanced process are available, which can be ideally matched to the task at hand, with high levels of produc- vity and economic effi ciency, and which deliver reliable,

reproducible results.

Electrochemical machining of metallic workpiecesIn the case of electrochemical machining (ECM), which is used in the fi elds of avia on and aerospace, the automo ve industry, toolmaking, medical technology, microsystems en-gineering, the energy industry and other sectors, metals are anodically removed from the surface of the workpiece. This procedure makes deburring possible in ‘diffi cult to access’ areas such as internal bore intersec ons and pockets, and also permits burr-free shaping processes. The machining tool, namely a cathode, and the compo-nent (as an anode) are connected to a generator which serves as a direct voltage source for the machining process. The component is machined accurately, inde-pendent of the metal’s amorphous structure, by means of the exchange of electrical charges which takes place between the cathode and the anode in an aqueous elec-

trolyte solu on. This makes it possible to produce even very small, thin-walled contours, fi llets, ducts, slots and wash-outs in workpieces made of prac cally any conduc- ve metal. Since processing is contactless, the tooling is

neither subjected to wear due to the machining process, nor is it exposed to thermal or mechanical infl uences.

The characteris cs and the shape of the tool holder determine where and how much material will be re-moved from the workpiece. Generator power is selected depending on the size of the surface to be machined, at any given point in me, and also determines the speed at which material is removed and the achievable degree of surface roughness. Newly developed generators reach Ra values of 0.1 μm and be er, depending on the ini al state. Beyond this, they also prevent so-called stray ma-chining which may lead to worse machining results at the anode’s peripheral areas.

Precision electrochemical machining As far as the actual processes are concerned, ECM and precision electrochemical machining (PECM) are both

based on exactly the same principle. Essen al diff er-ences include the distance from the cathode to the workpiece, on the one hand, and the use of an oscillat-ing cathode in the PECM process, on the other hand. Similar to EDM, with PECM it is possible to produce extremely accurate three-dimensional shapes, contours and structures, with very high levels of surface quali-ty. Ra values of down to 0.03 μm can be achieved. As compared to the EDM process, with PECM, machining is more accurate, with regard to component dimensions and tolerances, and it does not result in any thermal infl uences. Signifi cantly reduced machining me is a further advantage of the PECM process, as opposed to conven onal manufacturing. Comparisons between a conven onal process for the produc on of a compo-nent, involving spark erosion, milling, drilling, grinding, deburring and lapping and a PECM process for the produc on of an iden cal component, with subsequent grinding, reveal a 90% reduc on in pure manufacturing me. In addi on to shaping, the PECM process is also

used for micro-structuring of surfaces, for example, in order to op mise tribological proper es.

Abrasive fl ow machining for surface fi nishingAbrasive fl ow machining (AFM) is used primarily for processing ‘diffi cult to access’ workpiece areas and internal surfaces of high-quality components made of metal and ceramics, which cannot be processed by means of conven onal procedures. Typical applica ons include rounding, polishing and deburring, as well as geometry op misa on and the minimisa on of surface tension. The workpiece or workpieces are clamped for processing, in one or more fi xtures at the AFM machine. The processing medium - abrasive par cles which are matched to the respec ve task, with regard to type, size and concentra on, and are embedded in a polymer mass of defi ned viscosity - is made to fl ow

through or over the areas of the components to be pro-cessed, in alterna ng direc ons, at a defi ned pressure level, by means of hydraulically powered pistons. The grinding medium func ons like a liquid fi le. Process pa-rameters are con nuously monitored in order to assure reproducible results.

The AFM process makes it possible to improve surface roughness by a factor of fi ve to eight, as compared with the ini al surface condi on. It is used, for example, in the automo ve, plas cs and aluminium industries, as well as in tool- and mould-making for the processing of, amongst other workpieces, impression dies, tablet moulds and deep drawing dies. AFM has proven its worth in other sectors, as well, including medical technology, avia on and aerospace, as well as tex le machinery manufac-turing. AM opera ons to make metallic components, as part of modern industrial produc on, is opening up an addi onal range of applica ons for AFM.

New perspec ves for barrel fi nishingSurf, stream and pulse fi nishing processes involve barrel fi nishing solu ons for individual part processing, which can be easily integrated into automated produc on lines. These new developments permit accurate, reliable de-burring, edge rounding, smoothing, grinding and polish-ing of high-quality, geometrically complex components, such as machine cu ng tools and implants, as well as motor, gearbox and turbine components, matched to manufacturing cycle me. These are tasks which have usually had to be completed manually in the past by means of me-consuming, costly processes because no automated solu ons were available.

The eff ects of pulse fi nishing are based on ideally matched rela ve mo on between the processing me-dium and the workpiece. For example, the workpiece is secured in a clamping collet and accelerated to a speed of up to 2000 rpm, decelerated and accelerated again in a

rota ng bowl within a very short period of me. Interac- on with the iner a of the processing medium, due to

the diff erent speeds of the workpiece and the abrasive par cles, results in targeted grinding ac on with accu-rate deburring, even in areas which have previously been inaccessible for barrel fi nishing, for example, cross-holes in hydraulic components.

Polishing with plasmaLike electropolishing, plasma polishing is an electroly c process, but it works with high voltage and an electrolyte based on a salt solu on which is considered ecologically harmless. This process results in the forma on of a plas-ma a er the anodically polarised metallic workpiece has been immersed into the electroly c bath. The plasma coats the workpiece, thus resul ng in reduced rough-ness, as well as the removal of organic and inorganic con-tamina on, with just a minimal loss of mass. Depending on the material specifi ca on, material abrasion typically lies between 2 μm per minute and 8 μm per minute, and achievable roughness values are less than 0.01 μm. The geometric shape of the component remains nearly unchanged.

With the help of plasma polishing, for which an electrolyte consis ng of 98% water and 2% salt is used, burrs as well as milling marks and material upturns have been removed and smooth, homogeneous surfaces have been obtained. Image by Plasotec GmbH.

DeburringEXPO 2019Which processes ensure reliable and econom-ically efficient deburring and production of precision surface finishes? Which new tech-nologies are available? Which criteria need to be taken into consideration for the selection of a suitable process?

Answers to these and many other questions will be provided at DeburringEXPO 2019, the 3rd Leading Trade Fair for Deburring Technol-ogy and Precision Surface Finishing, which will be held at the Karlsruhe Exhibition Centre, Germany, from 8 to 10 October 2019.

The exhibition portfolio includes equipment, systems and tools for belt grinding, brushing, abrasive flow machining, vibratory grinding, blasting with solid and liquid media, abrasive water-jet blasting, magnetic-abrasive de-burring, ultrasonic deburring, chemical bath deburring, electrochemical machining (ECM), electron beam machining, thermal energy ma-chining (TEM), mechanical deburring, buffing, polish honing, electrolytic polishing, plasma polishing, laser polishing, immersion and brush polishing, as well as measuring, test and analysis systems, and technical literature.

IES UPDATE

To help expand the pool of cer fi ed professionals in li and escalator inspec on, IES Academy (IESA) and Temasek Polytechnic (TP) jointly launched the Li & Escalator Inspector (LEI) Course on 15 April 2019.

The new LEI course equips par cipants with in-depth knowledge and competence for the inspec on of li and escalator installa on and maintenance works, in accordance to prevailing standards.

Currently, owners of passenger li s and escalators must conduct an examina on, inspec on and tes ng of li s and escalators annually. If their ver cal transporta on systems fulfi l all requirements, a Permit-to-Operate will be issued.

Cer fi ed inspectors will be allowed to assist Specialist Professional Engineers (SPEs) in carrying out relevant du es during such inspec ons.

The course is open to individuals who have at least a diploma in mechanical or electrical engineering. The full course fee is SGD 2,500, with up to 95% funding available.

IES and the Associa on of Consul ng Engineers Singapore (ACES) are also working with government agencies to launch an LEI Registry to cer fy and maintain qualifi ed technical professionals in this area.

To be registered, candidates need to a end the LEI course run by IESA and TP, or that conducted by BCA Academy.

“Inspec on of li s and escalators is a cri cal component of ensuring safety and reliability for their users. IES seeks to contribute to the building of a strong core of professionals cer fi ed to carry out inspec on du es with high levels of competence through this course with Temasek Polytechnic and through future ini a ves such as the set-up of the LEI Registry,” said Mr Mervyn Sirisena, IES Vice-President for the Educa on Group.

Mr Cheah Swee Hock, Deputy Director of TP’s School of Engineering, added: “The posi ve response to the inaugural run of the course is encouraging. TP is delighted to collaborate with IES to provide relevant training to strengthen in-demand skills and capabili es for the transforma on of the li and escalator industry.”

There are currently about 60,000 passenger li s and about 6,000 escalators in Singapore, with just slightly over 80 li and escalator SPEs (who are able to perform li and escalator inspec ons and cer fi ca ons) currently registered with the Professional Engineers Board.
