Dr. Safa Laith Keelan, along with the participation of Professor Dr. Anas Qusay Hashim, Head of the Department of Biomedical Engineering, and Lecturer Dr. Mahmoud Hamid Majid—faculty members of the Department of Biomedical Engineering at the College of Engineering, Al-Nahrain University—participated in the Fourth International Conference on Engineering Sciences, hosted by the College of Engineering / University of Diyala. This participation was part of the conference’s scientific activities aimed at supporting scientific research and promoting academic knowledge exchange.

During the conference, Dr. Safa Laith Keelan presented a research paper entitled:
“Performance Evaluation of Biomedical ECG Suction Electrodes with Different Mathematical Methods.”

The paper addressed the performance evaluation of suction electrodes used in electrocardiography (ECG) by applying different mathematical methods, highlighting the importance of this topic in improving the accuracy of biomedical measurements.

This scientific participation represents an important opportunity to strengthen research collaboration between Al-Nahrain University and local as well as international academic institutions, in addition to contributing to scientific knowledge exchange and advancing the level of research in support of the university’s academic and research mission.

The participation in the Fourth International Conference on Engineering Sciences aimed to present specialized research findings in the field of Biomedical Engineering, contribute to enriching scientific discussions, and exchange research expertise with scholars from various universities and academic institutions. It also sought to enhance scientific cooperation between Al-Nahrain University and other universities, and to keep abreast of the latest research developments in biomedical engineering, thereby contributing to the advancement of scientific research and the improvement of academic performance at the university.

The research aims to evaluate the performance of biomedical suction electrodes used for recording cardiac electrical signals (ECG) by applying a set of different mathematical methods to analyze the efficiency and accuracy of these electrodes in capturing vital signals. Comparative analyses were conducted using multiple mathematical approaches to demonstrate the effect of each method on signal quality, particularly in terms of noise reduction and improved clarity of cardiac waveforms.

The study concluded that there are noticeable differences in the performance of suction electrodes depending on the mathematical method used, which contributes to identifying the optimal approach for improving the accuracy of cardiac diagnosis. The significance of this research lies in supporting the development of biomedical measurement technologies and enhancing the quality of biomedical signals used in clinical and research applications.
