Technical ReportOpen accessIn the abstractEffects of Design Factors of HDFS on I/O PerformanceHan-Gyoo KimFour major design factors of HDFS, the block size, the number of data nodes, the number of client processes and replication factor are investigated to find out the effects on the I/O performance of HDFS by performing experiments in a real physical HDFS infrastructure consisting of 64 Hadoop data nodes of Intel i9 based blades. The block size is observed … …Journal of Computer Science, Vol. 14, Issue 3 · 13 Mar 2018 · 7,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractRRDVCR: Real-Time Reliable Data Delivery Based on Virtual Coordinating Routing for Wireless Sensor NetworksVenkatesh, Chanchal Singh Sengar, Kuppanna Rajuk Venugopal et al.Real-time industrial application requires a routing protocol that guarantees data delivery with reliable, efficient and low end-to-end delay. Existing Two-Hop Velocity based Routing (THVR) protocol relates two-hop velocity to end-to-end delay to select the next forwarding node, that has the overhead of exchanging control packets and depleting the available energy in nodes. We propose a Real-Time Reliable Data delivery based … …Journal of Computer Science, Vol. 14, Issue 1 · 3 Jan 2018 · 8,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Intelligent Approach to Develop, Assess and Optimize Energy Consumption Models for Air-Cooled Chillers using Machine Learning AlgorithmsMostafa Tahmasebi, Nabil NassifThe building sector accounts for more than 70% of the total electricity use. Chillers consume more than 50% of electrical energy during seasonal periods of building use. With the growth of the building sector and climate change, it's essential to develop energy-efficient HVAC systems that optimize the ever-increasing energy demand. This study aims to develop an energy consumption prediction model … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 8 Nov 2022 · 5,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnomaly Detection Algorithms for Streaming Data: Performance ComparisonZirije HasaniToday’s most of the data are streaming time-series data, where is very important anomaly detection over this data because gives significant information of possible critical situations. Detecting anomalies in big streaming data is yet difficult task because we have to process them in real time, even before they are stored and instantly alarm on potential threats.
