Research ArticleOpen accessIn the abstractDeveloping an Effective Churn Prediction Model for Telecommunications: Enhancing Customer Retention through Advanced Machine Learning TechniquesAshu Goyal, Anuj Gupta, Sharad Kumar et al.Customer churn poses a significant challenge for the telecommunications sector, resulting in substantial revenue losses and increased customer acquisition costs. This research creates an efficient churn prediction model that combines state-of-the-art machine learning with ensemble learning to maximize customer retention. With the IBM Telco Customer Churn dataset, several baseline models, including Gradient Boosting, AdaBoost, Logistic Regression, Random Forest, and Support … …Journal of Computer Science, Vol. 22, Issue 1 · 3 Feb 2026 · 3,173 accessesView PDFCite
Review ArticleOpen accessIn the abstractAI-Driven Innovations in Meat Quality and Safety: Applications, Challenges, and Future DirectionsEmrobowansan Monday IdamokoroArtificial Intelligence (AI) is revolutionizing the meat sector by improving efficiency, accurateness, as well as sustainability in meat production, quality evaluation, and safety control. The conventional systems of meat inspection, handling, and processing are usually time consuming, labour-intensive, prone to contamination during handling and often susceptible to human errors. The use of artificial intelligence to drive technologies, including Deep Learning … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 28 Jan 2026 · 3,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractMERAKI: An Online Collaborative Learning Platform Developed Using the UWE MethodologyPercy De-la-Cruz-VdV, Yesenia Torres-Donayre, Hugo Vega-Huerta et al.In the digital era, education has evolved with the integration of technologies that optimize the teaching-learning process. This article presents the need for more efficient online collaborative environments that overcome the limitations of traditional platforms, fostering meaningful interaction between students and teachers. To address this need, the collaborative platform “MERAKI” was developed using the UML-Based Web Engineering (UWE) methodology. This … …Journal of Computer Science, Vol. 21, Issue 12 · 10 Jan 2026 · 2,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,178 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Plant Species Suitability for a Substrate-Free Tropical Green RoofBruno R. Silva, André Mantovani, Dulce G. Mantuano et al.Greenroofs reduce building exterior-interior thermal flux and mitigate high internal air temperatures, especially in tropical climates. Tropical greenroofs are given little attention and their use remains restricted to a very low percentage of roofs due to high costs compared to traditional roofs, weight overload (mainly due to the chosen substrate) and potential waterproofing problems. We here present an alternative greenroof … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 11 Oct 2018 · 7,529 accessesView PDFCite
Case ReportOpen accessIn the abstractQuery Optimization on Distributed Database Dengue Fever by Minimizing Attribute InvolvementSlamet Sudaryanto Nurhendratno, Sudaryanto, Fikri Budiman, Maryani SetyowatiQuery optimization is an important task in a client/server environment of a distributed database, whereas a health epidemiologist data distribution based on DBD data on Geographic Information Systems (GIS). A proper method for a particular query process function is needed to generate query optimization on a distributed database. The query process requires important attention especially in distributed databases because the … …Journal of Computer Science, Vol. 14, Issue 4 · 7 Apr 2018 · 8,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractModel for Automated and Improved Utilization of Existing Computer Resources on an Example of Web ServersDino Alagić, Ivan MagdalenićInformation technology is under constant innovation pressure to provide the highest level of data availability – i.e., the continuous functioning of operating systems. This is the very reason for an accelerated development of complex systems encompassed by the term cloud computing. Among other things, such solutions are aimed to ensure high-level availability of complex systems and architecture. Numerous studies indicate … …Journal of Computer Science, Vol. 14, Issue 2 · 2 Mar 2018 · 8,275 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Review on Ramie (Boehmeria nivea L. Gaudich.): From Textile to Medicine and the Threats of Pests and DiseasesVictor Corbita, Mari Neila Seco, Leny Galvez et al.Ramie (Boehmeria nivea L. Gaud.), also known as “China grass”, is a perennial herbaceous plant of the Urticaceae family. Ramie is considered one of the ancient and important economic and natural fiber crops today. Indeed, ramie fiber ranks first in durability, tensile strength, length of fiber cells, fineness, and color. Aside from its role in the textile industry, ramie is … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 2 Dec 2025 · 3,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractPleural Effusion Detection Using Optimized Pretrained ModelsRehab Fathi Ibrahim, Nashwa Mohamed Elsayed et al.Pleural effusion is an abnormal accumulation of fluid in the pleural cavity, posing a significant thoracic issue with various causes. Even with a variety of diagnostic techniques, accurate diagnosis remains challenging. Delays in diagnosis and treatment heighten the risks of the disease. In this paper, we introduce a novel approach by leveraging the Grey Wolf Optimizer (GWO) to systematically optimize … …Journal of Computer Science, Vol. 21, Issue 8 · 17 Oct 2025 · 2,317 accessesView PDFCite
