Abstract

Due to recent pandemic, 2021 International Conference on Detection Technology and Intelligence System (DTIS 2021) was held virtually online during December 3-5, 2021. The decision to hold the virtual conference was made in compliance with many restrictions and regulations that were imposed by countries around the globe. Such restrictions were made to minimize the risk of people contracting or spreading the COVID-19 through physical contact. There were 90 individuals who attended this on-line conference, represented many countries including Malaysia, Iran, and India.The 2021 International Conference on Detection Technology and Intelligence System (DTIS 2021) is to bring together innovative academics and industrial experts in the field of Detection Technology and Intelligence System to a common forum. The primary goal of the conference is to promote research and developmental activities in advanced Detection Technology and Intelligence System is to promote scientific information interchange between researchers, developers, engineers, students, and practitioners working all around the world.During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 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 the second part, we invited three professors as our keynote speakers. Prof. Dejie Yu, Hunan University, China. Prof. Dejie Yu's research areas are equipment condition monitoring and fault diagnosis; dynamic signal analysis and processing; automotive vibration and noise control (NVH); research on the properties and applications of phononic crystals/acoustic metamaterials; and research on the mechanical properties of acoustic metamaterials. And then we had Prof. Aihua Dong, Zhengzhou University of Economics and Business, China. Prof. Dong is mainly engaged in electrical automatic control, fault detection and other directions of scientific research. Lastly, we were glad to invite Assoc. Prof. Zhaojing Tong, Henan Polytechnic University, China. Assoc. Prof. Zhaojing Tong is mainly engaged in teaching and research in intelligent detection and equipment fault diagnosis, automatic control, intelligent reasoning, etc. Their insightful speeches had triggered heated discussion in the third session of the conference. Every participant praised this conference for disseminating useful and insightful knowledge.List of Committee are available in this pdf.
