Research ArticleOpen accessPhrase 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 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 titleAnalysis of a Two Unit Standby Oil Delivering System with a Provision of Switching Over to another System at Need to Increase the AvailabilityUpasana Sharma, Rekha, Gulshan TanejaProblem statement: The study deals with a standby system consisting of two units. Initially one unit is operative and the other is standby. When both the units are failed then there is a provision of switching over to the other similar system. This practical situation may be observed in an oil refinery plant. Real data on failure and repair rates … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,107 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAsymptotic Confidence Limits for a Repairable System with Standbys Subject to Switching FailuresJau-Chuan Ke, Ssu-Lang LeeThis paper studies system performance measures and asymptotic confidence limits for the mean time to failure, steady-state availability, steady-state failure frequency of a repairable system which two primary units, two standby units, and one repair facility when switching to standbys may fail. …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,922 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Switching Mechanism Detection to Reduce Complexity in Multiuser Detection for DS-CDMA SystemsRekha Agarwal, B. V.R. Reddy, K. K. AggarwalWe present a reduced complexity switching mechanism which uses either matched filter or Parallel Interference Cancellation (PIC) detector based on channel characteristics. The main criterion of taking PIC detector is that it has less Bit Error Rate (BER) and less processing delay than other nonlinear multiuser detectors. This proposed detector reduces overall complexity while maintaining the same performance as PIC … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2007 · 6,641 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMODELLING THE SWITCHING LINK AND MATHEMATICAL OF ACTUAL TRAFFICAbed Saif AlghawliThe paper represents the research results of studying the switches. The model of a switching link has been suggested. The switch has been presented in the form of a Queuing System (QS), the study of dynamic characteristics of switches has been undertaken and the adequacy of the proposed model of a switching link to actual switches has been valued. The … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the keywordsController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,904 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStabilization of a Nonlinear Delay SystemWalid Arouri, Elyes Maherzi, Mongi Besbes, Houda Ben Attia SethomProblem statement: The analysis and control of delayed systems are becoming more and more research topics in progress. This is mainly due to the fact that the delay is frequently encountered in technological systems. This can affect their significantly operations. Most control command laws are based on current digital computers and delays are intrinsic to the process or in the … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 31 Jan 2012 · 6,844 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance 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 PDFCite
Research ArticleOpen accessIn the abstractClimate-Driven Productivity Responses and Implications for Genetic Adaptation and Breeding of Boreal Trees in KazakhstanZhadyra Baigazakova, Kuralay Mazarzhanova, Asset Satayev et al.Kazakhstan’s boreal and forest-steppe forests form the southern ecotonal edge of the West Siberian taiga, where relatively small changes in heat and moisture can trigger disproportionate impacts on tree growth, mortality, and regeneration. Although forests cover only ~4% of Kazakhstan, they provide critical ecosystem services: stabilizing hydrological regimes, buffering microclimates, protecting agricultural lands from wind and water erosion, and supporting … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 10 Aug 2026 · 709 accessesView PDFCite
