　　Intrduction of content：

　　Many people are confused between measurement and monitoring systems. As scientists and engineers we have been trained to do specific measurements of a parameter (e.g., pressure) that can be quantified against a known standard and free from interference from other parameters (e.g., temperature). Monitoring is perceived as doing measurements over time and quantifying trends. However, there is an alternative approach that allows for both following trends but also provides a holistic view of the behavior of a system. The method can also bring together outputs of different measurements and/or sensor systems to provide an overview of a system. Furthermore, this alternative technique can pick events from what looks like noise in the data to emergent behavior in complex systems. Examples will be given to highlight the power of the technique from an engineering perspective which may also be applicable to many areas of science.

　　Brief introduction to the speaker：

　　J．W．Spencer is a Professor of Electrical Engineering in the Department of Electrical Engineering and Electronics at the University of Liverpool. He received the B.S. and Ph.D. degrees in electrical engineering from the University of Liverpool (UoL) in 1981, and 1984, respectively. He was a dean of the School of Electrical, Electronic and Computational Sciences (2011-2014), a director of the Department of Electrical and Electronic Engineering (2009-2011), and a dean of the Graduate School of Engineering(2006-2009) in the UoL. He currently is a fellow of the Institute of Engineering Technology (IET), a director of the Research Center for Intelligent Monitoring Systems in the UoL, and a financial director of the International Gas Discharge and Applications International Series Conference Management Committee. He also is a member of the Current Zero Club (The current zero club is a select group of internationally renowned academics, industrialists and consultants in the power/energy technology area), and a member of the International Academic Committee of the State Key Laboratory of Electrical Insulation and Power Equipment at Xian Jiaotong University. His research interests include physical properties of high temperature gases, high-current equipment such as circuit breakers, and application technology of semiconductors to electric power equipment, intelligent monitoring systems, and renewable energy. He has published more than 150 papers on the internationally top journals (e.g., IEEE Transactions on Power Electronics, IEEE Transactions on Industrial Electronics).
