SUMMARY:Extreme Spatial Multiplexing: A Fluid Antenna System Approach
DESCRIPTION:Abstract\nFluid antenna system (FAS) represents shape-flexible position-flexible antenna technologies for wireless communications and has recently emerged as a new degree of freedom for wireless communication design and optimization. The unique feature of FAS also changes the way in which interference is mitigated. In this talk\, we will first take a closer look at massive multiuser MIMO (multiple-input multiple-output) and discuss why massive MIMO alone cannot be a feasible solution for extreme spatial multiplexing of an enormous number of users. We then present how FAS at each user can reduce the burden of the base station and enable massive MIMO to handle a huge number of users with little channel state information (CSI) at the base station. The results reveal that 1000 of users can be served on the same physical data channel if massive MIMO combines with FAS. The talk will be concluded by sharing some recent updates on the implementation of FAS. \nSpeaker\nProf. Kai-Kit WONG\nProfessor of Wireless Communications\,\nUniversity College London \nBiography of the Speaker\nProf. Kai-Kit WONG received the BEng\, the MPhil\, and the PhD degrees\, all in Electrical and Electronic Engineering\, from the Hong Kong University of Science and Technology\, Hong Kong\, in 1996\, 1998\, and 2001\, respectively.

SUMMARY:Stabilizing Control Interactions of Converter-Based Resources
DESCRIPTION:Abstract\nThe widespread use of power electronic converters in renewable energy resources and flexible ac or dc transmission systems is profoundly changing dynamics and control of power systems. These converter-based resources are significantly different from synchronous generators in respect to their physical properties and control dynamics. The differences pose challenges to the stability and power quality of electricity supply. This lecture will give an overview of instability issues caused by dynamic interactions of converter-based resources\, and then discuss dynamics analysis and control methods for addressing the problems. Emerging trends and challenges with grid integration of converter-based resources will also be covered. \nSpeaker\nProf. Xiongfei WANG\nProfessor\,\nKTH Royal Institute of Technology\,\nStockholm\, Sweden \nBiography of the Speaker\nProf. Xiongfei WANG is currently a full-time Professor at the Department of Electrical Engineering\, KTH Royal Institute of Technology\, Stockholm\, Sweden\, a part-time Professor at Aalborg University\, Aalborg\, Denmark\, and a Visiting Professor at Hitachi Energy Research Center\, Vasteras\, Sweden. His research interests include modeling and control of power electronic converters\, stability and power quality of power-electronic-dominated power systems\, and high-power converters. He is an IEEE Fellow and the Executive Editor (Editor-in-Chief) for the IEEE Transactions on Power Electronics Letters\, as well as an Associate Editor for the IEEE Journal of Emerging and Selected Topics in Power Electronics. He received 10 IEEE Prize Paper Awards\, the 2016 AAU Talent for Future Research Leaders\, the 2018 Richard M.

SUMMARY:Open-Source Ultra-Low Power Edge AI Systems for a Connected World
DESCRIPTION:Abstract\nEdge computing is becoming an essential concept covering multiple domains nowadays as our world becomes increasingly connected to enable the Internet of Things (IoT) concept. In addition\, the new wave of Artificial Intelligence (AI)\, particularly complex Machine Learning (ML) and Deep Learning (DL) models\, is demanding new computing paradigms beyond traditional general-purpose computing to make IoT a viable reality in a sustainable world. In this seminar\, Prof. Atienza will discuss new approaches to effectively design the next generation of ultra-low power edge AI computing architectures by taking inspiration from how biological computing systems operate. In particular\, these novel bioinspired edge AI architectures include two key concepts. First\, it exploits the idea of accepting computing inexactness and integrating multiple computing acceleration engines and low-power principles to create a new open-source eXtended and Heterogeneous Energy-Efficient hardware Platform (called x-HEEP). Second\, x-HEEP can be instantiated for different application domains of edge AI to operate ensembles of neural networks and federated learning to improve the ML/DL outputs’ robustness at system level\, while minimizing memory and computation resources for the target application. Overall\, x-HEEP instantiations for edge AI applications included in-memory computing or run-time reconfigurable coarse-grained accelerators to minimize energy according to the required precision of the target application. \nSpeaker\nProf. David ATIENZA\nProfessor\,\nHead of the Embedded Systems Laboratory (ESL)\,\nScientific Director of the EcoCloud Sustainable Computing Center\,\nEPFL\, Switzerland \nBiography of the Speaker\nProf. David ATIENZA is a professor of Electrical and Computer Engineering\, and leads both the Embedded Systems Laboratory (ESL) and the new EcoCloud Sustainable Computing Center at EPFL\, Switzerland. He received his M.Sc. and Ph.D. degrees in Computer Science and Engineering from UCM (Spain) and IMEC (Belgium). His research interests include system-level design methodologies for high-performance multi-processor system-on-chip (MPSoC) and low-power Internet-of-Things (IoT) systems\, including edge AI architectures for wearables and IoT systems as well as thermal-aware designs for MPSoCs and many-core servers.

SUMMARY:A Memristor-based Hybrid Analog-digital Cerebellum (Small Brain) for Mobile Robotics
DESCRIPTION:Abstract\nAlgorithms for mobile robotic systems are generally implemented on purely digital computing platforms. As complementary metal-oxide-semiconductor (CMOS) scaling approaches the end of the road\, the improvement of the throughput of digital processors and computing power efficiency is nearing its end. This issue not only affects the power requirements of large data centers but also limits the performance of mobile robotic systems with perception and actuation. Developing alternative computational platforms may lead to more energy-efficient and responsive mobile robotics. \nInspired by how human and animal brains work\, we report a hybrid analog-digital computing platform enabled by memristors on a mobile inverted pendulum robot. The “cerebellum” (sensor fusion + motion control) of this mobile robotic system is implemented in memristor-based analog circuits\, and the rest of the system is implemented in digital circuits. Such a platform can perform computation in the analog domain and thus removes the speed and energy efficiency bottleneck. The robot using the hybrid analog-digital platform demonstrated dramatic enhancement of speed and energy efficiency over the traditional digital platform. \nSpeaker\nProf. Wei WU\nProfessor\,\nMing Hsieh Department of Electrical and Computer Engineering\,\nUniversity of Southern Californi \nBiography of the Speaker\nProf. Wei WU graduated from Peking University with a BS in Physics in 1996 and received a Ph.D. in Electrical Engineering from Princeton University in 2003.
