Research ArticleOpen accessIn the abstractTrajectory Tracking Control of UR5 Robot Manipulator Using Fuzzy Gain Scheduling Terminal Sliding Mode ControllerAndualem Welabo, Gebremichael TesfamariamrIn dealing with the trajectory tracking control of robotic manipulator many scholars have had to work in a sliding mode controller. However, SMC has two major limitations one is chattering the other is asymptotical convergence. The chattering problem occurs in traditional SMC due to the switching function of the discontinuous controller and the constant gain parameter of K. Though in … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 24 Jul 2020 · 11,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractPsychological Acceptability Weighted Priority Scheduling: A Case Study of Animal HospitalKitsiri Chochiang, Araya Choothong, Prakasit Intarasombat et al.A solution to the patient scheduling problem for a case study animal hospital called Mix+Factor scheduling is proposed in this work. Mix scheduling is based on the weighted sum of patient arrival order, the job type and the priority. The priority is based on the veterinarian opinion on the treatment type. Factor is an additional function based on the psychological … …Journal of Computer Science, Vol. 15, Issue 7 · 26 Jul 2019 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetaheuristic Algorithms for Independent Task Scheduling in Symmetric and Asymmetric Cloud Computing EnvironmentNagwan M. Abdel Samee, Sara Sayed Ahmed, Rania Ahmed Abdel Azeem Abul SeoudCloud Computing (CC) is a recent technology in the Information and Communication Technology (ICT) field. It provides an on-demand access to the shared pool of resources via virtualization. Large enterprises move toward CC due to its flexibility and scalability driven from its elastic pay-per-use model. To provide ensured efficient performance to users, tasks should be efficiently mapped to available resources. … …Journal of Computer Science, Vol. 15, Issue 4 · 3 May 2019 · 7,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Viral System Algorithm in Load Balancing of Cloud EnvironmentDamodar Tiwari, Shailendra Singh, Sanjeev SharmaAs the cloud computing technology is gaining popularity with time, more and more users and applications are shifting towards it. This is why clouds are experiencing high load, which demands for load balancing of user tasks submitted to cloud for execution. This makes load balancing of non-preemptive tasks a key issue in cloud computing. Superior task scheduling leads to balanced … …Journal of Computer Science, Vol. 14, Issue 7 · 14 Jul 2018 · 8,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractLPSO: Another Algorithm for Workflow Scheduling in the CloudToan Phan Thanh, Loc Nguyen The, Said Elnaffar, Cuong Nguyen DoanAlthough workflow scheduling problem has been discussed by many researchers, a few efficient solutions have been introduced for Cloud computing. In this article, we present LPSO, a novel algorithm for workflow scheduling. Based on the Particle Swarm Optimization method, our proposed algorithm not only ensures the fast convergence but also avoid being trapped on local extrema. Our simulation experiments using … …Journal of Computer Science, Vol. 12, Issue 12 · 12 Feb 2017 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Preemptive Global Utility Accrual Real Time Scheduling Algorithms in Multicore EnvironmentIdawaty Ahmad, Mohamed Othman, Zuriati Ahmad ZulkarnainThis paper proposed an efficient real time scheduling algorithm using global scheduling paradigm running in multicore environment known as Global Preemptive Utility Accrual Scheduling (GPUAS) algorithm. The existing TUF/UA multiprocessor scheduling algorithms known as Greedy-Global Utility Accrual (G-GUA) and Non Greedy-Global Utility Accrual (NG-GUA) algorithms is seen to overlook the efficiency on its task scheduling algorithm. These algorithms have adapted … …Journal of Computer Science, Vol. 11, Issue 12 · 11 Feb 2016 · 6,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticast Node Communication Using Virtual Queue with Process SchedulingS. Sumalatha, G. Sreenivasulu, G. Uday Kiran BhargavaMulticast technique is used to transmit node data from one source node to many destination nodes simultaneously and establish a communication in the network. In multicasting communication, node network packet collision occurrence is a frequent problem in real time network system. The node packet collision avoidance using virtual queue with process scheduling is discussed in this study and proposed central … …Journal of Computer Science, Vol. 11, Issue 2 · 28 Jan 2015 · 6,181 accessesView PDFCite
