Prof. Wuqiang Yang
The University of Manchester, UK

 

Professor Wuqiang Yang is a Fellow of the IET (formerly IEE), Fellow of the Institute of Measurement and Control and Fellow of the IEEE. He was also an IEEE IMS Distinguished Lecturer (2010-2016) and JSPS Invitation Fellow (2016). Since 1991, he has been working with The University of Manchester (formerly UMIST) in the UK and became Professor of Electronic Instrumentation in the School of Electrical and Electronic Engineering in 2005. His main research interests include industrial tomography, especially electrical capacitance tomography (ECT), inverse problem and image reconstruction, instrumentation and multiphase flow measurement. He has published over 500 papers, is a referee for over 50 journals (including 6 IEEE journals), Associate Editor of IEEE Trans. on Instrumentation and Measurement, editorial board member of 6 other journals (including Meas. Sci. and Technol.), guest editor of many journal special issues and visiting professor at several other universities. His biography has been included in Who’s Who in the World since 2002.

 

Speech Title: "Electrical Capacitance Tomography and Industrial Applications"

 

Among various industrial tomography modalities, electrical capacitance tomography (ECT) is the most mature and has been used for many challenging applications. ECT is based on measuring very small capacitance and reconstructing the permittivity distribution in a cross section of an industrial process, such as a multiphase flow or a fluidised bed. The internal information obtained by ECT is valuable for understanding complicated phenomena, verifying CFD models and simulation results, measurement and control of complicated processes. Compared with other tomography modalities, ECT has several advantages of no radioactive, fast response, both non-intrusive and non-invasive, withstanding high temperature and high pressure and of low-cost. Because of very small capacitance to be measured (down to 0.0001 pF) and the "soft-field" nature, ECT does present challenges in circuit design, solving the inverse problem and re-engineering. Our latest AC-based ECT system can generate online images at 300 frames per second with a signal-to-noise ratio (SNR) of 73 dB. Examples of industrial applications include the measurement of gas/oil/water flows, wet gas separation, pneumatic conveyors, cyclone separators and fluidised beds for pharmaceutical manufacturing and clean use of coal by circulating fluidised bed combustion and methanol-to-olefins conversion. During this talk, ECT will be discussed from principle to industrial applications, together with a demonstration of an AC-based ECT system.

Speech Title: "Security Analyses of Singular Value Decomposition(SVD)-Based Digital Watermarking"

 

Digital watermarking is the process of concealing secret information, called watermark, in a digital medium. There are many criteria to consider when choosing a watermarking scheme. These include imperceptibility, robustness as well as capacity. SVD-based watermarking can offer good imperceptibility, robustness and high capacity. Hence there are many watermarking techniques are being proposed based on SVD. However a common weakness is that SVD-based watermarking is possible to suffer false positive problem(FPP). Satisfying robustness and imperceptibility requirements, as well as preventing FPPs, in SVD-based image watermarking is crucial in applications such as copyright protection and authentication. During this talk, the false positive problem of SVD-based watermarking techniques will be demonstrated and possible solutions of overcome it will be discussed.
