Research ArticleOpen accessIn the keywordsThe Prevalence of Computer-Related Musculoskeletal Pain Among College Students-a Cross-Sectional StudyVenkatesan Rajagopal, Rosmah Mohd Rosli, Pederlia Rintai et al.Problem statement: In the recent years, there has been an increase in incidence of musculoskeletal complaints among college students. Potential risk factors for this might be increased use of computers. The purpose of this study was to examine among college students (a) the prevalence of musculoskeletal pain and (b) the association of musculoskeletal pain with computer use and physical activity … …Current Research in Medicine, Vol. 3, Issue 1 · 23 Feb 2012 · 9,676 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContributions Concerning Muscle Training in Professionnal VolleyballNiculescu Mugurel, Niculescu Ionela, Amzăr Elena LuminiţaProblem statement: Complex muscle training, less known to our specialists, has proved that, by complying with all the stages proposed, high level results may be achieved. The performances, weaker and weaker, obtained by the Romanian teams call for measures of optimization and Specific Physical Training (SPT) in accordance to technical -tactical training. Physical training should be individualized and multiplied, under … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractPost-COVID Impact Analysis and Effective Recommendation Solutions Over Risk Prediction Using Hybrid ModelBoddeti Jaggan Mohan Ravi Kumar, P. V. G. D. Prasad Reddy, G SrinivasThe COVID-19 pandemic (2019-2022) resulted in significant global mortality, largely attributed to the virus's unpredictable pathophysiology, rapid disease progression affecting multiple organ systems, and initial lack of effective treatments. This study systematically examines post-COVID-19 complications across major organ systems, including respiratory dysfunction, cardiovascular complications, renal disorders, musculoskeletal pain, gastrointestinal disturbances, neurological sequelae, alopecia, endocrine and metabolic dysregulation, and mental health … …Journal of Computer Science, Vol. 21, Issue 11 · 23 Dec 2025 · 1,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopological Approach for Mechatronic SystemsDamasse Harold Tchouazong, Jean Bosco SamonIn this study, we propose a topological methodology for mechatronic systems which is much more focused on the mechanical part of the mechatronic system based on the work of Casner. The methodology starts with the optimization of the electronic and control models (control command). Then, a characterization is done to highlight the optimization constraints that may affect the mechanical model. … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 26 Sep 2024 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractProsthetic Knee Mechanism Using a Double Locking System as a Safety MeasureEicarl Saynes Vazquez, Esther Lugo GonzálezThe design of a four-link knee prosthesis mechanism with two locking systems activated during the flexion/extension phase is presented. The first is geometric, totally mechanical and activated by the user's weight. The second is variable and is activated automatically when walking on irregular or special surfaces is required. The links' dimensions were selected using the differential evolutionary optimization algorithm to … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 12 Feb 2024 · 5,706 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 · 711 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Comprehensive Survey on Applications, Challenges, Threats and Solutions in IoT Environment and ArchitectureSadia Waheed, Savera Hanif, Rubab Hafeez et al.The influence of the Internet of Things (IoT) on how people live, interact and conduct business has rapidly increased. Integrating physical objects with electronic networking, or the Internet of Things (IoT), allows for better communication and environment detection. In coming years, higher service levels will be offered by IoT-based technologies, remarkably changing how people would conduct their daily lives. Currently, … …Journal of Computer Science, Vol. 20, Issue 3 · 30 Jan 2024 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling IoT Systems with UML: A Case Study for Monitoring and Predicting Power ConsumptionMarla Teresinha Barbosa Geller, Anderson Alvarenga de Moura MenesesSoftware Engineering has evolved to meet the growing complexity of current systems and the resources of the Unified Modeling Language (UML) enable the modeling of such systems in different views. The Internet of Things (IoT) paradigm appears with very peculiar characteristics such as the heterogeneity of its physical and virtual components that must be integrated. Designing systems of this nature … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 1 Feb 2021 · 8,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractExplosion of the Science Modification of Newtonian Dynamics Via Mach’s Inertia Principle and Generalization in Gravitational Quantum Bound Systems and Finite Range of the Gravity-Carriers, Consistent Merely On the Bosons and the FermionsMohsen LutephyNewtonian gravity is modified here via Mach's inertia principle (inertia fully governed by universe) and it is generalized to gravitationally quantum bound systems, resulting scale invariant fully relational dynamics (mere ordering upon actual objects), answering to rotation curves and velocity dispersions of the galaxies and clusters (large scale quantum bound systems), successful in all dimensions and scales from particle to … …Physics International, Vol. 11, Issue 1 · 10 Aug 2020 · 7,785 accessesView PDFCite
