ME MPhil students win 2nd Runner-up at IET Young Professionals Exhibition & Competition 2021

A team of 2 MPhil students from the Department of Mechanical Engineering (ME) of The Hong Kong Polytechnic University (PolyU) won the 2nd Runner-up (Postgraduate Section) for their outstanding performance at the Young Professionals Exhibition and Competition held on 1 Aug 2021. The team members, Daniel Kwong Tak Chun and Tommy Tsoi Man Ho, supervised by Dr Tracy Choy Yat Sze, competed with other local universities by a project “A Method for Online Auditory Assessment and Therapy on Pattern Recognition under COVID-19 Pandemic”. The project was concerned with designing a remote acoustic control method for health services through online conferencing software. The COVID-19 pandemic has impacted our society in various ways. Healthcare services with a face-to-face setting are urged to search for a new delivery mode in order to ensure the safety of clients and providers. When using various video conferencing software, we often encounter different sound responses and limitations. Users' computers also have various sound performances. These restrictions greatly affect the accuracy and reliability of the health assessment or therapy. In this project, a low-cost processor was used to design the platform such that service providers could remotely play the desired audio files on the client's side without suffering from the loss of sound in terms of frequency range and loudness due to the video-conferencing software. Experimental results showed that this remote control of audio playback could be realized with a low-cost processor called microcontroller unit (MCU) based on pattern recognition on client incoming audio frequency and it was able to deliver the audio files accurately in terms of frequency and amplitude. The Young Professionals Exhibition & Competition (YPEC) is an annual event organized by the Younger Members Section of the Institution of Engineering and Technology Hong Kong (IET Hong Kong). The YPEC acts as a dynamic platform for prospective or young engineers to exhibit their engineering projects with presentations and exhibitions. The YPEC 2021 themed “Transformer” aimed for bringing in new ideas to foster the transformation into a brand-new era.

ME Student Team won Outstanding Award in ASM Technology Award 2021

The PolyU ME student team won the Outstanding Award in the ASM Technology Award 2021. The team members, KHALID Farhan, SAFIULLAH Saad Bin and TAHIR Abdullah, supervised by Dr An Liang, competed with other local universities by a project “Design and Development of an Electrochemical Flow Cell for Green Ammonia Production from Renewable Energy”. Throughout the implementation of this project, our postdoc fellow Dr Pan Zhefei gave inspiring guidance and zealous support. The project is concerned with the development of an emerging ammonia production technology – electrochemical cells, which can utilize renewable power (from solar or wind energy) to drive the conversion from nitrogen to ammonia under ambient condition, achieving energy, environmental and economic sustainability. By utilizing the flow cell design concept, the results have shown that the flow cell structure dramatically upgraded the ammonia production rate. Hence, this significant advance opens a window of opportunity for breakthroughs in the development of ammonia production technology, making the technology to be closer to reality. The ASM Technology Award is launched by ASM Pacific Technology Limited (ASMPT) in 2015 for final year students in Hong Kong. It promotes technological innovation, and honours the best and brightest students with their outstanding final year projects on technology and innovation.

Deepest condolences to our Centenarian Alumnus Mr Cheung Tsang-wai

The Department is sadly to learn that Mr Cheung Tsang-wai (張增衛校友), the oldest alumnus of PolyU, passed away on 12 May 2021 at the age of 100.  We extend our deepest sympathy and condolences on the loss of Mr Cheung. When the University’s predecessor Government Trade School (the School) was founded in 1937, Mr Cheung was among the first cohort of students who enrolled to study mechanical engineering. Eighty years after his graduation, Mr Cheung is still very supportive of his alma mater and loves to participate in events organized by PolyU. Born in 1921, the centenarian, who graduated in December 1940 with a Diploma in Automobile Engineering, still has vivid memories of his student life. “The School was a red-brick three-storey building on Wood Road, Wanchai. Classes for mechanical engineering were held on the ground floor,” he said. Having Mr Cheung among our alumni is a blessing for the Department. He reflects the long history of ME which dates back to the Government Trade School (1937-1947) to provide technical education to youngsters, the Department has gone through different stages of transformation. May his soul rest in peace. We will always remember this wonderful man in our thoughts.  

PolyU ME Research Outputs 90% rated as World Leading & Internationally Excellent in Research Assessment Exercise (RAE) 2020

The University Grants Committee (UGC) announced the results of Research Assessment Exercise (RAE) 2020 on 24 May 2021, which cover the research performance of 8 UGC-funded universities from 1 Oct 2013 to 30 Sept 2019. The research performance of the Department of Mechanical Engineering (ME) at The Hong Kong Polytechnic University (PolyU) has been assessed using international benchmarks based on the research output (70%), impact (15%) and environment (15%). The Unit of Assessment (UoA) consisting of PolyU ME, Department of Industrial and Systems Engineering, and Institute of Textiles and Clothing has achieved overall 41% in world leading standard (4*), the 3rd among all universities in the same UoA. More specifically, the research outputs by 26 staff members in PolyU ME have been rated 43% as world leading (4*) and 47% as internationally excellent (3*) in terms of originality, significance and rigour, more than doubled in the 4*+3* rating from RAE 2014 results. We are very pleased with this year’s RAE results that PolyU ME research outputs achieved 90% in the top-notch ratings of 4* and 3*.  In particular, the sector average of the world leading standard (4*) among UoA 14 research outputs is 29% while ME achieved 43%. These results highlight the excellence and continuous improvement of our world leading research. PolyU ME will continue to conduct research that leads to original, significant and rigorous research outputs, as well as far-reaching and significant impact to the society.
