Experience: Prof. Yuen is a Distinguished Professor of Civil and Environmental Engineering (CEE). He also serves as a Council Member of the Escola Superior das Forças de Segurança de Macau (ESFSM) and Member of Board of Trustee of the Science and Technology Development Fund (FDCT) of the Macau SAR Government. Prof. Yuen' s research interest includes Bayesian inference, model selection, model updating, structural health monitoring, structural reliability, and structural vibration control. His paper “Model selection using response measurements: Bayesian probabilistic approach" (coauthored with J.L. Beck) is one of the top 10 most cited papers among all papers published in the Journal of Engineering Mechanics (established since 1983) of the American Society of Civil Engineers. Furthermore, his single-author book "Bayesian methods for structural dynamics and civil engineering" (published by John Wiley & Sons in 2010) has attracted great attention of Bayesian methods for structural dynamics. It has become a classical reading in this research field. In 2012, he was elected in the National Science and Technology Award Panel Expert Bank and the National Science and Technology Programs Expert Bank of the Ministry of Science and Technology, People's Republic of China. His major awards include: Young Investigator Award, International Chinese Association on Computational Mechanics; QIAN Weichang programme scholar, K.C. Wong Education Foundation; and Phi-Tau-Phi Honorary member.
Title:Robust optimal sensor configuration design
Abstract:Although the problem of optimal sensor placement (OSP) has been studied for a few decades, some further computational aspects regarding OSP have been studied recently. In this talk, we will propose a new approach for robust sensor placement. In the literature, OSP has always been considered for the case in which all sensors function well. However, this is not necessarily the case in real practice. We will present an algorithm to handle possible malfunctioned sensor and we will illustrate that the sensor configuration obtained by this algorithm is different from the traditional one.

Title:Structure design of extreme size antenna based on electromechanical coupling theory
Abstract: With the gradual implementation of a number of major projects in the country, such as centimeter-class unmanned payload platforms, QTT Radio telescope for odd platforms, and large-scale spaceborne deployable antennas, the design of the antenna in the size, gain, bandwidth, frequency band and so on also put forward more and more high, even extremely demanding requirements. On the one hand, long-distance and high-precision detection requires a 100-meter aperture antenna to achieve high gain, while a micro-payload platform requires the antenna structure size to continuously develop towards the centimeter, micron or even nanometer scale, thus better with the platform to adapt to achieve the overall mobility and concealment. However, the current design methods of traditional antennas have touched the technical ceiling of narrow vertical mining space and slow horizontal development speed. Only by means of multi-source information fusion in multi-subject and multi-field, can the innovative design of new antenna with extreme size break the theoretical shackles of traditional antenna design, and give a new direction.
In this report, the application and development of electromechanical coupling theory in antenna structure design and optimization are introduced by taking three extreme size antennas such as magneto-electric thin film antenna, nano-rectifying antenna and flexible shaped antenna as examples. The report includes the basic design theory of the three antennas, the requirements of the key structural factors affecting their performance, the design, preparation and testing of the samples. Finally, the key scientific and core technical problems of extreme size antenna design and optimization are summarized and refined, which lays a theoretical foundation for extreme size antenna design in our country.
