It was a great pleasure to welcome all the participants from different countries to the 2021 6th International Symposium on Advances in Electrical, Electronics and Computer Engineering (ISAEECE 2021) in Nanjing, China during March 12-14, 2021. ISAEECE 2021 is to bring together innovative academics and industrial experts in the field of electrical, electronics and computer engineering to a common forum. The primary goal of the conference is to promote research and developmental activities in electrical, electronics and computer engineering and another goal is to promote scientific information interchange between researchers, developers, engineers, students, and practitioners working all around the world. The conference will be held every year to make it an ideal platform for people to share views and experiences in electrical, electronics and computer engineering and related areas.The conference model was divided into two sessions, including oral presentations and keynote speeches. In the first part, some scholars, whose submissions were selected as the excellent papers, were given 15 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In this conference, we were greatly honor to have invited four outstanding researchers to serve as our Conference Chairman.During the conference, we invited three industry elites to present their insightful speeches. The first keynote speaker, Dr. Sunil Kumar Jha, from Nanjing University of Information Science and Technology, China. He presented a speech: Data Fusion Approaches in Human Body Odor Data Mining. The objective of the present research talk is to introduce audience about the data fusion and human body odor and to demonstrate research results related to search for an optimal subset of VOCs in body odor, which can produce differentiation in an individual by using the combination of analytical methods and chemometric analysis. The second keynote speaker, Prof. Chunbo Xiu, from Tiangong University, China. He shared a speech on his specialty related to Memristive Cellular Neural Network & Its Dynamic Characteristic Analysis. He demonstrated that chaotic memristive CNN system can be used in the secure communication by the chaos synchronization based on sliding mode control. Assoc. Prof. Pavel Loskot, from Zhejiang University-University of Illinois at Urbana-Champaign Institute (ZJUI), our third keynote speakers. He presented a speech: Monte Carlo Simulations Revisited. Their insightful speeches made every participant praised this conference for disseminating useful knowledge.We were 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: Electronics Engineering, Electrical Engineering, Computer Engineering and other related topics. All the papers have been through rigorous review and process to meet the requirements of International publication standard.We were grateful to the International/National advisory committee, keynote speakers, session chairs, organising committee members, student volunteers and administrative assistance of the management section of University, including accounts section, digital media and publication house. Also, we were thankful to all the authors for contributing large number of papers in the conference, because of which the conference became a story of success. It was the quality of their presentations and their passion to communicate with the other participants that really make this conference series a great success.The Organizing Committee of ISAEECE 2021List of Committee member are available in this pdf.
