I have given 20 keynote speeches for International conferences.
Abstract
Virtual reality is a computer simulation system that can create and experience virtual worlds. It uses a computer to generate a simulated environment to immerse users in the environment. Virtual reality technology uses data in real life, electronic signals generated by computer technology, combined with various output devices to make it a phenomenon that people can feel. These phenomena can become real objects in reality or a substance . We cannot see with the naked eye, this is expressed through a three-dimensional model. Because these phenomena are not what we can see directly, but the real world simulated by computer technology, they are called virtual reality. In my research, I studied the application of virtual reality in geoinformatics, molecular biology and neurorehabilitation, and developed some augmented reality interactive technologies. Finally, I introduced the research of Hash geocoding and blockchain in virtual reality geographic information system.

John Thompson received the Ph.D. degree in electrical engineering from University of Edinburgh, Edinburgh, U.K., in 1995. He currently holds a personal chair in Signal Processing and Communications at the School of Engineering, University of Edinburgh. He specializes in antenna array processing, energy-efficient wireless communications and the application of machine learning to wireless communications problems. To date, he has published in excess of 350 papers on these topics. His work has been regularly cited by the wireless community and from 2015 to 2018, he was recognized by Thomson Reuters as a Highly Cited Researcher. He is currently an area editor handling wireless communications topics for the IEEE Transactions on Green Communications and Networking journal. In January 2016, he was elevated to Fellow of the IEEE for Contributions to Antenna Arrays and Multihop Communications.
Abstract
In 2030, wireless systems will evolve significantly from current networks to provide more integrated and energy efficient solutions. Additionally, wireless designers are increasingly targetting higher frequencies in the millimetre wave and even terahertz bands to provide increased capacity. In this talk we will discuss the design of large scale antenna array technologies to provide energy efficient communications for such systems. We will discuss two approaches to save energy in such systems. The first is to minimise the number of activated radio frequency chains to minimize energy consumed while achieving the desired performance goals. The second focuses on improving the efficiency of channel training techniques for directional data transmission. We present a novel algorithm to achieve high communications performance while minimising the required training transmissions.

Abstract
As Organisations are increasingly adopting cloud-computing (centralised and/or decentralised) as the foundation for their IT infrastructure, the reliability of inherently complex cloud systems becomes under test. The robustness of these infrastructures and services and the overall resilience is, generally, enhanced by creating redundancy for backup in times of fault, failure or attack. Concepts and processes existing as nature's inherently multifunctional capabilities such as robustness, resiliency, survivability, and adaptability, could provide inspiration for unconventional methods to solve unique problems in the computing continuum. Ensuring the resilience of critical infrastructures is ever more necessary with the increasing threat of cyber-attacks, due to the increased complexity. It is generally acceptable that whilst complexity increases resilience and reliability decreases. However Biological systems subvert this rule; they are inherently much more complex, yet highly reliable. This talk will review and define resilience disciplines and techniques for cloud computing, then draws parallels between resilience capabilities in nature such as those demonstrated in multi-cellular biological systems and capabilities in cloud environments.
