Research ArticleOpen accessIn the abstractDeveloping a Linear Quadratic Regulator for Human Lower Extremity Exoskeleton RobotSk Khairul Hasan, Anoop DhingraDuring the last two decades, exoskeleton robot-assisted neurorehabilitation has received a lot of attention. The major reason for active research in robot-assisted rehabilitation is its ability to provide various types of physical therapy at different stages of physical and neurological recovery. The performance of the robot-assisted physical therapy is greatly influenced by the robot motion control system. Robot dynamics are … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 23 May 2022 · 7,602 accessesView PDFCite
Research ArticleOpen accessIn the abstractTAGN-IDC: Implicit Discrete Constraints for Tsunami Aware Graph Neural Networks in Spatial Evacuation RoutingSularno, Wendi Boy, Putri Anggraini et al.Tsunami evacuation route requires rapid identification of safe evacuation paths under dynamically changing hazard conditions. A major challenge is incorporating hard binary road-blockage constraints caused by tsunami inundation while maintaining end-to-end differentiability for deep learning models. Existing approaches commonly rely on continuous relaxations or stochastic sampling techniques, which either compromise physical feasibility or increase computational complexity. This study proposes the … …Journal of Computer Science, Vol. 22, Issue 9 · 24 Sep 2026 · 704 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Self-Esteem and Body Dissatisfaction Among Jamaican Youths: Unraveling Influential Factors and Promoting Positive Self-ImageDenise LloydThis qualitative study explores body image and self-esteem perceptions among Jamaican youths aged 9-15, framed within a Participatory Action Research (PAR) approach. PAR, grounded in critical theory and social constructivism, emphasizes collaborative inquiry, cyclical reflection, and action to address social issues relevant to the participants' lived experiences. This methodology is particularly suited for youth-centred, culturally situated research, as it empowers … …Current Research in Psychology, Vol. 11, Issue 1 · 9 Jan 2026 · 3,367 accessesView PDFCite

Research ArticleOpen accessIn the abstractEvaluation of Binary and Ternary Models in Powder Packing Density for Additive Manufacturing ApplicationsTaher M. Abu-Lebdeh, Oluwatobiloba Adetokunbo KalejaiyePowder packing is a very important aspect of additive manufacturing (3-D printing), as it directly impacts the final physical and mechanical properties of the printed objects. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed product, which also contributes to the surface finish. In order to achieve the densest packing for a powder, different sizes … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 15 Jun 2021 · 7,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Kidney Stone Detection Accuracy Using Image Processing and a Hybrid Convolutional Deep Belief NetworkGeetha M. N, Barkathulla A, S. Nandhini Devi et al.Automated CKD is a rapidly expanding non-communicable ailment that significantly contributes to global mortality and morbidity. CKD impacts more than 10% of the worldwide population, leading to millions of deaths annually. This paper proposes an enhanced deep learning model for renal disease detection that integrates convolutional and involution layers to enhance classification accuracy. CKD is a worldwide health issue characterised … …Journal of Computer Science, Vol. 22, Issue 10 · 9 Oct 2026 · 749 accessesView PDFCite

Research ArticleOpen accessIn the abstractTrends in Preventive Behaviors Across Countries: An Exploratory Study of English Language TweetsHiroyasu Furukawa, Ryoki KobayashiPeople take preventive behaviors to keep themselves from harm and protect themselves from physical harm, psychological threats, or health issues. Previous studies have suggested that preventive behavior trends are closely connected to cultures and values. However, the specific preventive behavior categories, their specific elements, and the preventive behavior differences between countries have never been fully examined. Therefore, using a topic … …Journal of Social Sciences, Vol. 18, Issue 1 · 20 Apr 2022 · 6,946 accessesView PDFCite
