Research ArticleOpen accessIn the abstractEmploying Hybrid Serial Cascaded Adaptive Network for Anomaly Detection and Prevention in IoT Time Series Data With Optimal Interdomain RoutingKante Satyanarayana, K. VenkateshNowadays, emerging Internet of Things (IoT) in data processing becomes interested research topic and is used for various applications. This varies from big data processing and analytics for accumulating entire sensor data to detect and generate long-term trends. Nevertheless, this results in the requirement for resources like the execution of power, memory, and bandwidth, in which resource-constrained IoT tools suffers … …Journal of Computer Science, Vol. 22, Issue 1 · 21 Feb 2026 · 1,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractPredictive Analytics and Procurement Visibility: A Big-Data-Driven Approach to Customer Satisfaction in Supply Chain ManagementDevendra Nath Pathak, Rakesh Kumar Yadav, Hitendra SinghIn the current dynamic and consumer driven market environment, supply chains need to move out of reactive to the proactive ecosystems. One of the most urgent requirements is increasing procurement visibility and the development of better order planning for the inventory to meet the products’ demand with continued high customer satisfaction. This paper is an agenda of big-data-driven predictive analytics … …Journal of Computer Science, Vol. 22, Issue 1 · 3 Feb 2026 · 2,442 accessesView PDFCite
Research ArticleOpen accessIn the abstractOffice Supplies Requisition-Disbursement System Processing on Cloud: Algorithms and Database Design TechniquesKriangsak Chanthinok, Ekkachai NaenudornDigitalbusiness organization is an organization that has applied informationtechnology to its operations and benefits from saving costs, saving resources,and making it quick to act and operate the business. However, manyorganizations lack systems to complement effectively internal management suchas in-house office supplies requisition-disbursement system. Past research papers have shown that a widerange of office supplies requisition-disbursement systems have been developed,but almost … …Journal of Computer Science, Vol. 18, Issue 10 · 13 Oct 2022 · 6,551 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 · 8,327 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Detection of Exudates in Retinal Images using Region-Based, Neighborhood and Block OperationKittipol Wisaeng, Worawat Sa-NgiamviboolExudates detection is one of the research areas attracting great attention of physicians and scientists. A region-based, neighborhood, block operation and optimal global thresholding are proposed as new methods to exudates detection. The exudates are coarse and fine segmentation following preprocessing steps, i.e., color mapping, image contrast enhancement, fuzzy filtering and optic disc localization. To classify the retinal images into … …Journal of Computer Science, Vol. 14, Issue 4 · 21 Feb 2018 · 7,982 accessesView PDFCite
Review ArticleOpen accessIn the abstractTEC-Driven Mini Refrigerators: Recent Applications With Performance CharacteristicsTamer Guclu, Pinar Mert Cuce et al.Thermoelectric Cooling (TEC) technology has become a remarkable alternative in mini refrigerator applications in recent years, thanks to its lack of moving parts, silent operation, compact structure and environmentally friendly features. This study aims to examine the current usage areas, performance characteristics, and engineering challenges of TEC systems in mini refrigerator applications with a holistic approach. Experimental and theoretical studies … …Energy Research Journal, Vol. 14, Issue 1 · 23 Dec 2025 · 3,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Forest and Extreme Gradient Boosting with Bayesian Hyperparameter Optimization for Landslide Susceptibility Mapping in Penang Island, MalaysiaDorothy Anak Martin Atok, Soo See Chai, Kok Luong Goh et al.Landslide susceptibility models often face challenges of overfitting and overestimation. This research focuses on improving the predictive capabilities of the Extreme Gradient Boosting (XGBoost) and Random Forest (RF) algorithms by applying Bayesian Hyperparameter Optimization (BayesOpt). Penang Island, a region in Malaysia prone to frequent landslides, was chosen as the study area. Ten Landslide Conditioning Factors (LCFs), including elevation, slope angle, … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 3,103 accessesView PDFCite
