Students Vu Phuong Thuy (2nd year), Nguyen Thi Huong (2nd year), Trinh The Tuan (3rd year) have won the first prize in the Student Scientific Research Competition, 2021-2022, with the guidance of Dr. Minhhuy Le. They will be attended the National Student Scientific Research Competition in the end of 2022.

Students Tran Mach Tuan Kiet guided by Dr. Nguyen Dang Khoa  has won the 3rnd prize in the same competition.
Congratulations on these efforts and success!

On June 15, 2020, the conference of scientific research students for the year 2020-2021 of the Faculty of Electrical and Electronics Engineering took place extremely successfully. The conference selected the top 3 groups of students from the faculty to attend the Phenikaa University Student Scientific Research Conference.

In particular, a student group consisting of 3 members, Tran Mach Tuan Kiet, Le Tien Dat, and Trinh The Tuan, with the guidance of Dr. Le Minh Huy, won the second prize and won tickets to the next round.

Research into the application of broadband Radar in human detection is a project to help evaluate the effectiveness of broadband Radar in detecting movements that focus on small movements such as breathing. The research team has experimented in the laboratory on cases where there are no people, there are people moving and there are people standing still, at this time the radar will detect small movements to detect whether there are people or not. After the research process, the team has obtained some positive results when Ultra-Wideband (UWB) Radar is evaluated well with accuracy up to more than 95%.

Congratulations on this effort and success.

Detection of corrosion at rivet sites in a multilayer structure of an aircraft is an essential task to ensure the flight safety of an aircraft. It is challenging to detect corrosion due to the influence on the signal of the rivet and the multiple fastened layers in the structure. Developing towards this research direction, Dr. Minhhuy Le, Dr. Van Su Luong, and Dr. Dang Khoa Nguyen of the ICSLab of Phenikaa University, and Prof. Jinyi Lee of Chosun University in Korea have done the research. As a result, a new article has been published about this content, which was published in the Journal of Nondestructive Evaluation (JONE – this is one of the top journals in the NDT field). In this paper, an electromagnetic testing method is used in conjunction with principal component analysis (PCA) to detect corrosion around fasteners. Multiple Hall sensors were used for efficient measurement of the magnetic field distribution at the rivet sites. The features of the scanned magnetic image were automatically extracted by the PCA in orthogonal subspaces. The proposed method shows potential results of features extraction and corrosion signal extraction for further development of electromagnetic testing systems in multilayer engineering structures. We are looking for further interesting results.

Big congrats to Prof. Van Su Luong, Prof. Minhhuy Le & Mr. Cong-Thuong Pham for their publications on the Journal of Magnetism and Magnetic Materials [1] and Apply Sciences [2].

Prof. Luong published his development of a magnetic flux-gate sensor using a differential exciting coil [1]. The sensor has a high sensitivity of 629 mV/mT and a noise level of 320pT/√Hz@1Hz that allows to measuring a weak magnetic field such as the earth's magnetic field.

Prof. Le and Mr. Pham published their co-work with Prof. Jinyi Lee at the IT-NDT Research Center, Chosun University, Korea, about the development of Nondestructive Testing (NDT) system for the inspection of water-cooled tubes in the power plants [2]. The NDT system integrated magnetic flux leakage testing and ultrasonic testing for both detection and quantitative evaluation of damage size.

This is the first hybrid conference: online-offline we have attended. This year, the ICCE conference was held at Phu Quoc Island, Vietnam. Totally, 86/173 papers were accepted for the presentation with authors from 25 countries. Phu Quoc Island is really beautiful with nice weather and long beaches.

At this conference, we present our research on measuring vital signs including respiration and heartbeat signals by using Ultra-wideband radar. Find our full publication at:
