射频脉冲的优化控制方法及其在核磁共振中的应用

题目: 射频脉冲的优化控制方法及其在核磁共振中的应用 (The Radio-Frequency Pulse Optimization Methods: Fundamentals and Applications in Magnetic Resonance)

智能系统与控制研究所223教室,2017年3月29日上午10点

摘要: 射频脉冲可实现自旋体系的精确操控,在核磁共振信号探测中起到关键作用,因此脉冲设计一直是核磁共振领域最活跃的研究前沿之一。报告将从磁共振射频脉冲的基本操控原理及其数学模型出发,介绍基于自旋动力学和优化控制理论的最优脉冲设计方法,通过实例展示优化脉冲在相关领域的应用前景,包括高性能的磁共振动力学模拟平台开发、不依赖于造影剂的对比度增强成像序列、用于伪纯态制备的协作脉冲序列和新型代谢物浓度定量脉冲序列等。

Speaker: Kok Lay Teo, John Curtin Distinguished Professor, Curtin University

Professor Kok Lay Teo received his Ph.D. degree in Electrical Engineering from the University of Ottawa in Canada. Professor Teo was affiliated with University of New South Wales, Australia, National University of Singapore and University of Western Australia. In 1996, He joined the Department of Mathematics and Statistics, Curtin University, Australia, as Professor of Applied Mathematics. He took up the position of Chair Professor of Applied Mathematics and Head of Department of Applied Mathematics at the Hong Kong Polytechnic University, China, from 1999 to 2004. He returned to Australia in 2005 as Professor of Applied Mathematics and Head of Department of Mathematics and Statistics at Curtin University until 2010. Professor Teo has been a John Curtin Distinguished Professor, the highest rank professor at Curtin University, since the beginning of 2011. Professor Teoserved as a member of the Australian Research Council’s Mathematical, Information and Computing Sciences Panel for the 2010 and 2015 Excellence in Research for Australia (ERA) Exercise. He was a Lecturer of the 2010-2011 Texas A&M University at Qatar Distinguished lecture Series, and the winner of the prestigious 2013 John de Laeter Research Leadership Award, Curtin University. Professor Teo is Editor-in-Chief of Journal of Industrial and Management Optimization (JIMO); Cogent Mathematics; and Numerical Algebra, Control and Optimization (NACO). He also serves as an Associate Editor of 12 international journals which include Automatica, Journal of Global Optimization (JOGO), Journal of Optimization Theory and Applications (JOTA), Discrete and Continuous Dynamical Systems (DCDS), Applied Mathematical Modelling, and Optimization Letters (OPTL).

In the last 5 years, Professor Teo has published over 100 refereed journal articles, many in leading international journals such as Automatica, Journal of Global Optimization, Journal of Optimization Theory and Applications, European Journal of Operational Research, and various IEEE journals.

Professor Teo was a Founding Member and member of the working committee of Pacific Optimization Research Activity Group (POP). Pacific optimization Research Activity Group (POP) is an important research organization with over 500 members from 50 different countries and regions. It has an electronic newsletter "Optimization Research Bridge" (ORB), three conference series (International Conference on Optimization: Techniques and Applications; Pacific Optimization Conferences; and International Conference on Optimization and Control with Applications), and two journals ("Pacific Journal of Optimization", and "Journal of Industrial and Management Optimization'' ). Professor Teo has served as the Chair of POP since 2015.

His research interests are optimal control and optimization and their real world applications, such as optimal filter design in signal processing and financial mathematics.

Control of linear hyperbolic PDEs for oil well drilling

Speaker: Florent Di Meglio, Centre Automatique et Systèmes, MINES ParisTech, PSL Research University, France

Time: 24, March, 2017 (Tuesday) Morning at 10:00

Room 223, Institute of Cyber-Systems and Control, Zhejiang University

Abstract: Oil well drilling involves many distributed parameter control problems, from the hydraulic transport of oil & gas to the propagation of mechanical vibrations. These require developing tools to analyze stability, boundary estimation and boundary stabilization for the underlying dynamics, which are governed by hyperbolic Partial Differential Equations. In this talk, I will give an overview of the state-of-the-art results in control theory for such systems and discuss their applicability to the industrial challenges mentioned above.
