Preface

It is over one year since COVID-19 broke out. The whole world is still struggling against the virulent pandemic COVID-19. It is still difficult to take international travel. Many conferences are held virtually, for the sake of protecting all the participants and conference staff from get infected by the virus. It is uncertain when the COVID-19 will end, so it remains unclear for postponement time, while many scholars and researchers wanted to attend this long-waited conference and have academic exchanges with their peers. Therefore, in order to actively respond the call of the government, and meet author’s request, 2021 2nd International Conference on Signal Processing and Computer Science (SPCS 2021), which was planned to be held in Qingdao, China from August 20 to 22, was changed to be held online through Zoom software. This approach not only avoids people gathering, but also meets their communication needs. The SPCS 2021 was organized by AEIC Academic Exchange Information Center. It dedicated to create a platform for academic communications between specialists and scholars in the fields of Signal Processing and Computer Science. The conference created a path to establish a research relation for the authors and listeners with opportunities for collaboration and networking among the universities and institutions for promoting research and developing technologies. The conference brings together about 90 well-known scholars in the field of Signal Processing and Computer Science at home and abroad. The reports were divided into keynote speeches, oral presentations, and poster presentations to share their latest research results and experiences in related research fields. In the first part, each keynote speakers were allocated 30 minutes to present their talks via Zoom. After the keynote talks, all participants joined in a WeChat communication group to discuss more about the talks and presentations. We were greatly honor to have invited seven distinguished experts as our keynote speakers. Prof. Roberto Montemanni, from University of Modena and Reggio Emilia, Italy was the first one to perform a thought-provoking speech: Artificial Intelligence Applications in Logistics. And then we had Assoc. Prof. Lingling An, from Xidian University, China. She presented an insightful speech: Enhancement Mechanism of Cerebellar Neural Network Dynamics. Prof. Xinsong Yang, from Sichuan University, China. He made a wonderful speech: Synchronization And Control for Differential Equations with Discontinuous State on the Right-Hand Sides. Prof. Xinhua Tang, from Southeast University, China. His research topics include GNSS receiver techniques, GNSS/INS integrated navigation system, Multi-source integration systems, Precision agriculture, Autonomous vehicles etc. Prof. Haibin Zhu, from Nipissing University, Canada. He delivered a speech: E-CARGO and Role-Based Collaboration. Assoc. Prof. Marcin Paprzycki, from Systems Research Institute, Polish Academy of Sciences, Poland. His original research interests were in the area of high performance computing / parallel computing / computational mathematics. Over time, they shifted towards intelligent systems, software agents and agent systems, and application of semantic technologies, among others. Our finale keynote speaker, Prof. Hoshang Kolivand, from Liverpool John Moores University, UK was invited to perform a speech: Current and Future of Directions of Augmented and Virtual Reality. Their insightful speeches had triggered heated discussion in the third session of the conference. The WeChat discussion lasted for about 30 minutes. Every participant praised this conference for disseminating useful and insightful knowledge. We are glad to share with you that we received lots of submissions from the conference and we selected a bunch of high-quality papers and compiled them into the proceedings after rigorously reviewed them. These papers feature following topics but are not limited to: Signal Processing, Applications of Signal Processing, Communication and Broadband Networks, Computational Science and other relevant directions. All the papers have been through rigorous review and process to meet the requirements of international publication standard. We would like to thank the organization staff, the members of the program committees and reviewers. They have worked very hard in reviewing papers and making valuable suggestions for the authors to improve their work. We also would like to express our gratitude to the external reviewers, for providing extra help in the review process, and the authors for contributing their research result to the conference. Lastly, we would like to warmly thank all the authors who, with their presentations and papers, generously contributed to the lively exchange of scientific information that is so vital to the endurance of scientific conferences of this kind.
