Research ArticleOpen accessPhrase in the titleNumerical Investigation of Flow Control by Suction and Injection on a Subsonic AirfoilM. H. Shojaefard, A. R. Noorpoor, A. Avanesians, M. GhaffarpourThis study presents a numerical study concerning flow control by suction and injection. The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach number of 0.15 are studied. Three cases are studied … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,434 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleRobust Decentralized Control of Unified Power Flow ControllerHossein Shayeghi, Ali AbdolalipourA new approach based on structured singular value is proposed for the robust decentralized Unified Power Flow Controller (UPFC) design. To achieve decentralization, using the schauder fixed point theorem the synthesis and analysis of Multi-Input Multi-output (MIMO) control system is translated into set of equivalent Multi-Input Single-Output (MISO) control system. Power systems such as the other industrial plants contain different … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,154 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePower System Oscillations Damping Using Unified Power Flow Controller-Based StabilizerLokman H. Hassan, M. Moghavvemi, Haider A.F. MohamedProblem statement: The Phillips-Heffron model of a power system with UPFC published by AJAS, demonstrates the effect of the UPFC in improving power system oscillation stability. Unfortunately, some of the equations have not been correctly derived and so working with this model in its existing form is misleading. Approach: In this study, the model is revisited and the equations are … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,939 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePurpose-based Versus Flow-Based Access Control for PrivacySabah Al-Fedaghi, Bashayer Al-Babtain, Maha Al-FahadProblem statement: Data protection legislation requires handling of Personal Identifiable Information (PII) in special ways to guarantee privacy. Specifically, the notion of handling purpose plays an important role in current access control mechanisms that allow only actions corresponding to intended purposes. A problem that arises in this context is how to ensure that PII is used solely for the intended … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,821 accessesView PDFCite

Research ArticleOpen accessIn the keywordsA Novel Time-Based Switch Migration Method (TSSM) for Load Balancing in Distributed Software-Defined NetworkingThangaraj E, Dinesh K, Prabhakaran Paulraj et al.Switch migration is predominantly used for workload balancing in distributed Software Defined Network (SDN) controllers. The Time-Sharing Switch Migration (TSSM) technique allowed the switch's responsibility to be divided based on the time duration condition of overload, which resulted in fewer overload events, fewer ping-pong controller issues, and more efficient controllers. However, it has higher controller resource utilization during TSSM working … …Journal of Computer Science, Vol. 22, Issue 3 · 6 Mar 2026 · 1,591 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffectiveness Analysis of Aspect-Oriented Dependence Flow Graph as an Intermediate Representation ToolSyarbaini Ahmad, Abdul Azim A. GhaniGraph-based representations of programs such as control flow graph or dependence graph have been used to support program analysis tasks such as program comprehension and software maintenance. However, in the case of Aspect-Oriented Programming (AOP), such graph representations individually is not enough to represent the features of aspect-oriented programs because it could need to identify the flow of control and … …Journal of Computer Science, Vol. 14, Issue 6 · 20 Feb 2018 · 9,109 accessesView PDFCite
