Dr. Jo Verhaevert is an Associate Professor at the Faculty of Engineering Sciences and Architecture, Ghent University. He has published over 80 papers, and currently conducts research in Computer Communications (Networks), Algorithms, and Communication Engineering.
We asked Dr. Jo Vernhaevert a couple of questions about the article.
What was the most interesting, challenging, or exciting aspect of working on this paper?
“We proposed a novel fall detection and warning system for nursing homes, relying on Bluetooth Low Energy wireless communication. This paper focuses on the hardware design of a fall-acceleration sensing wearable for the elderly and on a novel algorithm for real-time filtering of the measurement data as well as on a strategy to confirm the detected fall events, based on changes in the person’s orientation.”
What, in your opinion, is the next big opportunity or challenge in your field?
“Vital sign monitoring”

2. ‘Clustering by Hybrid K-Means-Based Rider Sunflower Optimization Algorithm for Medical Data' by A. Jaya Mabel Rani and A. Pravin
This study published in Advances in Fuzzy Systems, was selected as an Article of the Year by the Chief Editor, because of its significance and interest within the research community, and having the potential to have real-world impact with increased visibility.
What is the article about?
The research introduces a hybrid optimization technique, the K-means-based rider sunflower optimization (RSFO) algorithm, for medical data clustering. The proposed approach involves data preprocessing to clean input medical data, selection of important features using the Tversky index with holoentropy, and clustering through the hybrid RSFO algorithm.
The findings include:
-
The proposed clustering algorithm effectively analyzes the risk factor of heart disease by producing an optimal centroid-based clustering solution for heart disease-based medical data.
-
The achieved performance of the proposed K-means-based rider sunflower optimization (RSFO) algorithm is noteworthy, with an accuracy of 90.0236%.
-
The hybrid clustering algorithm, combining rider optimization and sunflower optimization techniques, demonstrates advantages such as protecting against premature convergence.
