Research ArticleOpen accessIn the abstractOptimal Rejuvenation Scheduling of Distributed Computation Based on Dynamic ProgrammingHiroyuki Okamura, Kazuki Iwamoto, Tadashi DohiRecently, a complementary approach to handle transient software failures, called software rejuvenation, is becoming popular as a proactive fault management technique in operational software systems. In this study, we develop the optimal scheduling algorithms to trigger software rejuvenation in distributed computation circumstance. In particular, we focus on two different computation circumstances in terms of detection of failures. Based on the … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,385 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPerformance Assessment of CPU Scheduling Algorithms: A Scenario-Based Approach with FCFS, RR, and SJFOlaa Hajjar, Escelle Mekhallalati, Nada Annwty et al.This study presents an extensive examination of CPU scheduling algorithms, focusing on the First-Come, First-Served (FCFS), Round-Robin (RR), and Shortest-Job-First (SJF) strategies through a carefully designed scenario-based approach. By deploying a Java-based simulation to dynamically generate random process arrival and burst times, this study simulates a variety of operational conditions to test these scheduling algorithms’ adaptability and performance in environments … …Journal of Computer Science, Vol. 20, Issue 9 · 16 Jun 2024 · 9,091 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOptimizing KNN for Face Recognition and Location Detection in Mobile Employee Attendance Systems Using Machine LearningPainem, Hari Soetanto, Achmad Solichin, Ibnu RamadhanEmployee attendance is critical to company operations, particularly for firms involved in ATM installations collaborating with banks. An effective attendance system enables bank vendors to verify the completion of ATM installations. The current attendance method employed by the company requires employees to send photos of themselves with the installed ATM, including the machine number and installation location. The company's admin … …Journal of Computer Science, Vol. 21, Issue 5 · 14 Apr 2025 · 5,989 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA DATA WAREHOUSE DESIGN FOR THE DETECTION OF FRAUD IN THE SUPPLY CHAIN BY USING THE BENFORD’S LAWCornelia Kraus, Raul ValverdeLarge data volumes and the inability to analyse them enables fraudulent activities to go unnoticed in supply chain management processes such as procurement, warehouse management and inventory management. This fraud increases the cost of the supply chain management and a fraud detection mechanism is necessary to reduce the risk of fraud in this business area. This study was carried out … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 7 Jul 2014 · 8,740 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Review of Environmental Management Systems in Global Defence SectorsXiao Hua Wang, Wen WuEnvironmental management is a key element in ensuring positive environmental performance of an organization. The integration of environmental management into military activities has also become a growing concern for defence sectors internationally. At present, an Environmental Management System (EMS) is one of the most widely used environmental management tools throughout the world. Recent research and public concerns have been increasingly … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 14 Apr 2013 · 8,188 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel µ-Negative Metamaterial With Enhanced Rejection BandwidthHaider Raad, Hussain Al-Rizzo, Ayman Abbosh, Said AbushamlehIn this study, a novel planar µ-Negative (MNG) metamaterial structure based on Split Ring Resonators (SRRs) with improved rejection bandwidth is presented. A bridging technique is used to connect two SRR unit cells at the center to emulate a cascaded filter. The proposed structure achieved a -20 dB rejection bandwidth of 15.5% compared to 4.5% for the conventional SRRs which … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 3 Apr 2013 · 7,372 accessesView PDF Cite
