Research ArticleOpen accessIn the keywordsA Novel Detection and Classification Algorithm for Power Quality Disturbances using WaveletsC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranThis study presents a novel method to detect and classify power quality disturbances using wavelets. The proposed algorithm uses different wavelets each for a particular class of disturbance. The method uses wavelet filter banks in an effective way and does multiple filtering to detect the disturbances. A qualitative comparison of results shows the advantages and drawbacks of each wavelet when … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,632 accessesView PDFCite

The aim of the research is to study and to prove the effective way of presowing treatment of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 17 Jun 2017 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Fast Series Active Filter using Sliding Mode Control to Correct and Regulate Unbalance Voltage in Three-Phase SystemTheerayuth ChatchanayuenyongProblem statement: A Sliding Mode Controller (SMC) with fast reference voltage generation to correct and regulate unbalance voltage in three-phase system was proposed. Approach: The compensation algorithm was not based on three-symmetrical component decomposition so the controller can yield a fast response that was essential in such a critical real time control work. The reference voltages were fed to the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,221 accessesView PDFCite
Research ArticleOpen accessIn the author namesCorrelation between Tissue and Released VEGF Levels in Urine of Bladder Cancer PatientsMenha Swellam, Abdulla A.A. El-AalPurpose. Angiogenesis is a complex multistep process essential for tumor growth. Vascular endothelial growth factor (VEGF) is a potent endothelial cell mitogen and vascular permeability-inducing agent. The aim of this study was to analyze whether tissue and urinary VEGF levels of bladder cancer patients are correlated and study their correlation with classical clinicopathological parameters and bilharizial bladder cancer patients. The … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,639 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlled Delivery System for NPK Agrochemical Release from Chitosan Copolymer HydrogelsMaysam S. Mutlaq, Fawzi Habeeb JabrailChitosan (CS) the polysaccharide was copolymerized with Poly (Vinyl Alcohol) (PVA) for the preparation of CS-co-PVA hydrogel and with Carboxymethyl Cellulose (CMC) for CS-co-CMC hydrogel. The prepared hydrogels were characterized by FTIR, thermal analysis (TGA and DSC), and SEM. The hydrogels were studied for agriculture applications, where their ability to swell and take large quantities of water many times its … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 8 Sep 2022 · 6,746 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Signal Processing Techniques for Detection of Power Quality EventsAbhijith Augustine, Ruban Deva Prakash, Rajy Xavier, Mareeta Cheriyan ParasseryThe challenging process industry requires true power for its smooth functioning and here comes the importance of good power or power. The term Power Quality (PQ) aims at supplying true power to the process. The scope of the power quality increased with the introduction of newly designed sophisticated devices like computers and microcontrollers. The performances of these devices are extremely … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 30 Apr 2016 · 8,493 accessesView PDFCite
