Research ArticleOpen accessIn the abstractEffects of Low Frequencies on Three Phase Induction Motor Performance Operating in Close Proximity to Rated SpeedQazem Jaber, Qais Naman, Mahdi ShamaseenVariable speed drives (VSD) are adhered to induction motors in most of the present industrial applications. And since the world has become more conscientious to energy saving, inverters established them selves in domestic buildings and industry. Square wave inverters generate dominant harmonics of the 5th, 7th, 11th and 13th order. Inverters based on PWM strategy produce much higher harmonic order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Traffic Flow and Management at Un-signalized, Signalized and Roundabout Road IntersectionsR. Kakooza, L.S. Luboobi, J.Y.T. MugishaTraffic congestion continues to hinder economic and social development and also has a negative impact on the environment. A simple mathematical model is used to analyze the different types of road intersections in terms of their Performance in relation to managing traffic congestion and to establish the condition for stability of the road intersections after sufficiently longer periods of time … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Voltage Stability and Alleviation Through Knowledge Based SystemA. Arunagiri, B. VenkateshModern power systems are large sized and rapidly growing. They require constant attention to monitor their performance. Attention is also required to ensure that the voltage stability margin of the power system is above a desired level. In order to achieve the objective, this study proposes a knowledge-based system. It computes using simple Fast De-Coupled Load Flow (FDLF), the state … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractCastor Oil Based Epoxy/Clay Nanocomposite for Advanced ApplicationsAditi Saikia, Niranjan KarakBio-based hyperbranched and linear epoxy resins were synthesized from monoglyceride of Ricinus communis oil. The nanocomposites of these hyperbranched and linear epoxies with 1, 2 and 3 wt% of OMMT were also fabricated. The structures of the resins and their nanocomposites were analyzed by FTIR, NMR, XRD, SEM and TEM. The studies of performance characteristics of poly(amido amine) cured thermosetting … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 29 Dec 2015 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoftware-based Control Algorithm for Providing Convergence Region with an Increasing Polynomial under Windowed FIR FiltersSergio Bimbi Junior, Vitor Chaves De Oliveira, Agenor De Toledo Fleury, Ronaldo RuasThis work developed a control algorithm for dynamical systems to high performance manner, in a way to produce an optimum output applying a modification in digital filters, capable of increasing the convergence zone within the desired cut -off frequency. Such task focused on consistently improving the challenge present in digital filters, which are time-invariant linear systems that are able to … …Journal of Computer Science, Vol. 14, Issue 7 · 17 Jul 2018 · 8,408 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Systematic Study of the Novel Materials used in Solar Cell Technologies, Opportunities and ChallengesAayush Kumar Choudhary, Godwin Glivin, N. Kalaiselvan et al.This study aims to review the present progress of integrating the PV cell with other prominent mainstream photovoltaic cell materials. The combination of the materials in a thin film electric cell is advantageous due to the reduction within the material usage and therefore the rise in efficiency. Amorphous Silicon (α-Si), Cadmium Telluride (CdTe) and Copper Indium Gallium Selenide (CIGS) are … …Energy Research Journal, Vol. 11, Issue 1 · 2 Nov 2020 · 7,356 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigate the Extrinsic and Intrinsic Motivational Factors of Knowledge Transfer in the HospitalsAhmad Aabed Al-Hayy Al-Dalaien, Sulfeeza Mohd Drus, Hairoladenan Kasim, Ali Taha Al-OqailyThe value of services in knowledge-intensive organizations like the hospitals is created by the tacit knowledge of the health staff. The weak knowledge transfer activities among the health staff effects on the performance level of the health care services. Hospitals are dependent on continuously learning from mistakes and to make improvements and then to transfer this newly acquired knowledge between … …Journal of Computer Science, Vol. 16, Issue 1 · 21 Jan 2020 · 7,728 accessesView PDFCite
