Prof. CHAI Yang publishes review article on multidimensional vision sensors

A review article by Prof. CHAI Yang, Associate Dean of the Faculty of Science (Research) and Professor in the Department of Applied Physics and his team, titled “Multidimensional vision sensors for information processing”, was recently published in the Nature Nanotechnology journal. The review delves into the hardware implementation of multidimensional vision sensors, and explores their working mechanisms and design principles. The team exemplified multidimensional vision sensors built on emerging devices and silicon-based system integration. They further provided benchmarking metrics for multidimensional vision sensors and concluded with the principle of device–system co-design and co-optimisation. Prof. Chai is currently Management Committee Member of the Research Institute for Intelligent Wearable Systems (RI-IWEAR), and Member of the Photonics Research Institute (PRI), the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE) and the Research Institute for Artificial Intelligence of Internet of Things (RIAIoT).

Member of Chinese Academy of Sciences to deliver seminar on shape memory polymer composites

PAIR cordially invites you to join our seminar on 15 July 2024 (Monday) at 2:30pm–4:00pm (Hong Kong time) on PolyU campus. The seminar titled “Shape Memory Polymer Composites: Programmability, 4D Printing and Applications” will be delivered by Prof. LENG Jinsong, Dean of School of Future Technology, Director of the Center for Smart Materials and Structures (CSMS), Director of International Center for Applied Mechanics at Harbin Institute of Technology (HIT), and Deputy Director of the Academic Committee of HIT, China. Shape memory polymers and their composites are smart materials with excitation response. They have the ability to maintain temporary shape and return to their original shape under specific external environment excitation. At present, shape memory polymers such as epoxy, cyanate ester, styrene, polyimide, polylactic acid, and polyurethane with adjustable glass transition temperatures have been developed. Smart structures prepared based on shape memory materials have unique shape memory properties and characteristics of lightweight and high strength and have the functions of active deformation, self-sensing and self-repairing. Prof. Leng and his research team have developed a variety of shape memory smart structures, which have been initially applied in aerospace, biomedical, 4D printing, and other fields. These materials offer significant promise for future smart products in many areas of science and technology. Prof. Leng is a Member of Chinese Academy of Sciences, the Foreign Member of Academia Europaea, Member of the European Academy of Sciences and Arts. His research fields include smart materials and structures, sensors and actuators, stimulus-responsive polymers (shape memory and electro-active polymers) and their composites, multifunctional nanocomposites, space deployable structures, 4D printing and biomedical applications, etc. He currently serves as Vice President of the International Committee on Composite Materials (ICCM), Vice President of Chinese Society of Aeronautics and Astronautics (CSAA), and Editor-in-Chief of the International Journal of Smart and Nano Materials (IJSNM). He was elected as Fellow of American Association for the Advancement of Science (AAAS), Fellow of the Society of Photo-Optical Instrumentation Engineers (SPIE), Fellow of American Society of Mechanical Engineers (ASME), Fellow of Institute of Physics (IOP), Fellow of Royal Aeronautical Society (RAeS), Fellow of Institute of Materials, Minerals, and Mining (IMMM) and Associate Fellow of American Institute of Aeronautics and Astronautics (AIAA).

Dr BU Siqi develops deep reinforcement learning-based framework for accurate prediction of photovoltaic power

Dr BU Siqi, Member of the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Associate Professor and Associate Head of the Department of Electrical and Electronic Engineering, and his teammates developed a novel deep reinforcement learning-based interpretable framework considering outliers for the accurate prediction of photovoltaic (PV) power. The study has recently been published in the journal Sustainable Energy Technologies and Assessments. The team utilised cutting-edge deep reinforcement learning-based interpretable models for predicting the occurrence of PV power outliers and improving PV power prediction accuracy. The proposed framework not only distinguishes outliers in forecast data, but also obtains complete outlier information with correct classification of PV power types, which can help engineers take emergency measures such as participating in demand response, increasing energy reserves, and optimising bids. The framework was verified on the actual operation data of the PV plant in Northwest China. The prediction performance of the proposed framework was analysed and compared with benchmark methods. Research results demonstrated that the proposed PV power prediction framework has great potential for application in future electric energy systems.

MHRC Member Dr Jessie LIN shares views on postpartum depression

Dr Jessie LIN, Member of the Mental Health Research Centre (MHRC) and Assistant Professor in the Department of Rehabilitation Sciences, shared her professional perspectives on postpartum depression in an interview with Bastille Post. Dr Lin explained that postpartum mothers can experience significant mood swings due to factors such as hormonal changes and challenges of maternal role adaptation. Family care and support can greatly help postpartum mothers to adapt to role changes and regulate emotions. She recommended seeking help from professionals as soon as possible should there be signs of postpartum depression or emotional distress.
