Research ArticleOpen accessEvery word in the titleDesign of a High-Performance IP Switching ArchitectureHattab Guesmi, Belgacem Bouallegue, Ridha Djemal, Rached TourkiIn this study we present the architecture for use in high-performance switching networks with support quality of service (QoS) guarantees. Quality of services guarantees in terms of delay, through-put and loss rate can be provided by using mechanism's support like scheduling and buffer management at switching architecture in packet switching networks. Our architecture is based on a new data structure … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,811 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOscillatory Dynamical Switching System of Bulk FerroelectricsM. N.A. Halif, S. Daud, Junaidah OsmanThis study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching to first and second-order phase transition, respectively. All the formalism is delineated in the framework of Landau free-energy expansion and Landau-Khalatnikov (LK) equation of motion where the effect of external energy may affray FE atoms similar to the spring damped oscillatory system. Here … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,677 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReal Time Hybrid Controller Implementation for Switched Reluctance Motor DriveS. Paramasivam, R. ArumugamThis study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under soft chopping operation. The … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,240 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSwitching from Flat to Spatial Motion to 3R Mechatronic SystemsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe anthropomorphic robots are part of the classical series of mechatronic systems, being in the form of arms and having at least three space rotation, to which other components may eventually be added, thus lengthening the entire kinematic chain. You can also add all the planetary or spatial rotating arms or others that are translating. At the end we always … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 22 Jan 2018 · 7,427 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHybrid Traffic Management Model for Multi-Protocol Label Switching NetworkE. R. Naganathan, S. RajagopalanProblem statement: MPLS is a highly scalable, protocol agnostic and data-carrying mechanism. Traffic engineering is the major research area in MPLS due to the emerging requirements of MPLS and the internet usage. A major objective of traffic engineering is to minimize or eliminate high-loss situations. Another goal of traffic engineering is to balance the Quality of Service (QoS) against the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,094 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMOLECULAR SWITCH THAT CONTROLS THE FLUX OF LINOLEIC ACID INTO N-6 OR N-3 POLYUNSATURATED FATTY ACIDS IN MICROORGANISMSMingxuan Wang, Jianxin Chen, Huaiyuan Zhang, Yuanda SongPolyunsaturated Fatty Acids (PUFA) of the n-6 and n-3 series play important roles in nutrition. Microorganisms are important sources of n-6 and n-3 fatty acids; however, most produce either n-6 or n-3 fatty acids as the major PUFAs and very few produce both. This differential production suggests that PUFAs metabolic pathway is strictly controlled in microorganisms. The major pathway of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 2 Jul 2014 · 7,131 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Lipid-Lowering Efficacy of Switching Within Non-Nucleoside Reverse Transcriptase Inhibitors in HIV-Infected PatientsA.M. Bain, K.D. Payne, A.P. Rahman et al.The objective of present research is to evaluate the lipid lowering efficacy and safety of switching within non-nucleoside reverse transcriptase inhibitors (NNRTI) in HIV-infected patients. This is a multicenter, retrospective study utilizing a comprehensive electronic patient registry to identify all adult HIV-infected patients seen from October 1, 1998 through October 1, 2006, who substituted efavirenz for nevirapine (EFV→NVP) or vice-versa … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 6,743 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNEW BURST ASSEMBLY AND SCHEDULING TECHNIQUE FOR OPTICAL BURST SWITCHING NETWORKSV. Kavitha, V. PalanisamyThe Optical Burst Switching is a new switching technology that efficiently utilizes the bandwidth in the optical layer. The key areas to be concentrated in Optical Burst Switching (OBS) networks are the burst assembly and burst scheduling i.e., assignment of wavelengths to the incoming bursts. This study presents a New Burst Assembly and Scheduling (NBAS) technique in a simultaneous multipath … …Journal of Computer Science, Vol. 9, Issue 8 · 6 Jul 2013 · 6,944 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicroelectrical Mechanical Systems Switch for Designing Multi-Band AntennaA.H.M. Zahirul Alam, Md. Rafiqul Islam, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: In this study Microelectrical Mechanical System (MEMS) switches were proposed to design a reconfigurable/multi-band antenna to replaced PIN diode switches or semiconductor switches due to lower insertion losses, good isolation, much lower intermodulation distortion, and lower power consumption. The antenna is able to operate at very high frequencies. Approach: A reconfigurable antenna that is capable to operate at … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 6,687 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Variable Neighborhood Search Algorithm for Assigning Cells to Switches in Wireless NetworksMatthieu Andr, Gilles Pesant, Samuel PierreThe problem of assigning cells to switches in wireless networks consists of minimizing the total operating cost, that is, the cost of linking cells to switches and the cost of handover from one cell to another, by taking into account factors such as network topology, switch capacity and traffic load in the entire network. Such a problem is well known … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,748 accessesView PDFCite
