ME PhD student received the 2019 HKIE Outstanding Paper Award for Young Engineers/Researchers

A ME PhD student received the 14th HKIE outstanding paper award for young engineers/researchers announced in the award ceremony on 20 Sep 2019 held by the HKIE Transactions Committee, The Hong Kong Institution of Engineers (HKIE). Structural health monitoring is a critical engineering issue attracting a lot of R&D strength from the literature and engineering areas in the past decades. Various complex structures including truss structures and satellites in space engineering, bridges and building structures in civil engineering, offshore structures in ocean engineering, water supply pipe systems, and railway systems etc are usually business-critical but may often suffer from vibration damage or fatigue problems, and eventually have structural cracks or bolt loosening issues. Timely structural health monitoring and regular maintenance are therefore greatly important to smooth operation of these structures and also highly relevant to public health and safety. The award-winning work is entitled by “A second-order output spectrum based method for detecting bolt-loosening fault in a satellite-like structure”, which is done by a ME PhD student, Mr Quankun Li, in the research group of nonlinear dynamics, vibration and control (NDVC) led by Dr Xingjian Jing. The work is about a systematic and effective method for accurately identify and locate potential crack or bolt-loosening faults in these aforementioned complex structures, based on a novel nonlinear feature of vibration response of structures using only several trails of vibration signals. Compared to existing results in the literature, this unique method can make full use of fault-incurred nonlinear features but minimize the influence of inherent nonlinear dynamics already existing in structures, and eventually can give more accurate and sensitive diagnosis on potential fault and its location. The method is developed based on a series of studies within Dr Xingjian Jing’s NDVC group on the theory and methods for analysis and design of nonlinear systems in the frequency domain in the past years. The work done by Mr Li has led to several publications in top international journals including Structural Health Monitoring (IF3.798, Rank 6/86 in Multidisciplinary Engineering), Mechanical Systems and Signal Processing (IF5.005, Rank 6/129 in Mechanical Engineering), Nonlinear Dynamics (IF4.6004, Rank 7/134 in Mechanics), and so on, and would have wide engineering applications. The HKIE Outstanding Paper Award for Young Engineers/Researchers 2019 is an international paper award which is organised in its 14th consecutive year. It is the HKIE ultimate goal to encourage young engineers and researchers to publish their works and advance in their professional findings, as well as to promote engineering among the younger generation. This competition is open to young engineers and researchers worldwide who are at the age of 35 or below. Three papers have been selected for the year’s Award. A Public Lecture will be organised for the three awardees to share and exhibit their findings and accomplishments in various engineering fields.

ME PhD student received Belt and Road Scholarship 2019/20

Every year, a number of scholarships and awards are offered by the HKSAR Government, and other public or private organizations to assist non-local students in financing their education in Hong Kong. Some are available solely for non-local students, and others are awarded on a competitive basis to all students regardless of nationality or residency status. To strengthen education collaboration with the Belt and Road countries, the Belt and Road Scholarships have been offered to students coming from designated counties along the Belt and Road regions since the 2016/17 academic year. To attract more non-local outstanding students to further their studies in Hong Kong, the Belt and Road Scholarship further expanded to cover all regions along the Belt and Road in the 2019/20 academic year. This year, our PhD student Luiza Labazanova coming from Russia was the recipient of the 2019/20 Belt and Road Scholarship (Research Postgraduate). Luiza received a scholarship to cover her full tuition fees and is tenable for the normal duration of the programmes concerned. The scholarship will be renewed annually subject to the satisfactory academic performance of the awardees. In the 2019/20 academic year, up to 20 Belt and Road Scholarships (Research Postgraduate) were offered to students from countries along the Belt and Road to study first-year full-time publicly-funded research postgraduate programmes in Hong Kong.

ME Student Team win Gold at ASM Technology Award 2019

A student team from the Department of Mechanical Engineering (ME) won the Gold Award for its ingenious robot design at the ASM Technology Award 2019.  The annual event has been organised since 2015 to recognise excellence in technology, showcasing outstanding final year projects of undergraduates from top faculties and schools of engineering in Hong Kong. PolyU's trio - Roy CHOW Hung-ming; Ji-ho SHIN; and Rudra Ajay SOMESHWAR, under the supervision of Dr Henry CHU, Assistant Professor, and Dr Curtis NG, Technical Support Group Leader, from the Department of Mechanical Engineering of PolyU, presented their final year project titled "ASME Competition Robot Development & Vision Based Target Alignment" and was honoured with the Gold Award at the competition. This was the fifth time that PolyU participated in the event and the second time that a PolyU team won the championship. The project developed by the PolyU winning team was a semi-automated robot with a unique gripper design for garbage collection with the aid of vision-based alignment. The robot featured a motorised platform for navigating a compact environment, a micro-controller system for wireless communication and control, and a vision-based system for object detection and robot positioning. It was developed in two stages with design inspiration from studying real-life tools such as robotic arms, forklift and dump cart. Initially, the team planned to design a robot for the Student Design Competition organised by the American Society of Mechanical Engineers (ASME), in which they were challenged to develop a fully functional prototype that can quickly and carefully pick up and return balls back to the starting area. The students then showed how their device could be transformed into an Automated Guided Vehicle (AGV) for garbage collection using advanced image processing techniques in the ASM Technology Award contest. "The students are eager to learn new knowledge and technology, and able to integrate them into the project to enhance the robot performance and functionality. They have developed new modules for the robot to demonstrate the potential of transforming it for use in real life," said Dr Chu.

ME PhD Students Won Student Competition Awards in ISSW32

Two ME PhD students, Liang Yu and Liu Lili won the Student Competition Awards in the 32nd International Symposium on Shock Waves (ISSW32) held at the Faculty of Engineering, National University of Singapore in Singapore on 14-19 July 2019. Since the inception of the International Symposium on Shock Wave (ISSW) in 1957, ISSW has served as authoritative platforms for the international scientific community to meet and exchange ideas on the study of shock wave and blast wave related phenomena and their applications. ISSW32 is a continuation in the series of biannual international symposia that have been held throughout the world. It had over 400 participants, including more than 370 overseas delegates. Student authors were encouraged to participate in the Student Competition. Winners were selected based on the best oral and poster presentations. Liang Yu and Liu Lili are both devoted to Richtmyer-Meshkov instability (RMI) investigation. RMI plays a crucial part in promoting the supersonic combustion efficiency but impeding the ignition in the Inertial Confinement Fusion. Therefore, it is significant to investigate how to improve or suppress RMI developments. Liang Yu reported “Evolution of an air/SF6/air Finite-thickness Fluid Layer Impacted by Shock Wave” and Liu Lili presented “Richtmyer-Meshkov Instability on Dual-mode Interface Impacted by Shock Wave”. Both of them concisely explained the interface coupling as well as compressibility effects on the fluid layer evolutions and the mode-competition effects on the multi-mode interface evolutions. The judging panel acclaimed their presentations, and each received an award of USD250. Both research study is under the supervision of Prof. Chih-yung Wen and affiliated to the High-speed Thermo-fluid and MAV/UAV Laboratory, Department of Mechanical Engineering, The Hong Kong Polytechnic University.
