Research ArticleOpen accessAll words, across the recordA 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
Review ArticleOpen accessAll words, across the recordAntihypertensive Effects of Brazilian FruitsAugusto Altoé Puppin, Christiane Mileib Vasconcelos, Mirian de Almeida Silva et al.Cardiovascular disease is a health problem that generates economic and social impacts worldwide and hypertension is a major risk factor for the development of cardiovascular disease. Currently, conventional medicine offers treatments that control and regulate blood pressure through medication, but the traditional medicines of different cultures have used plants and foods to treat and prevent this type of disease for … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 19 Jun 2020 · 7,187 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCalcium-sorbitol Chelating Technology and Application in PotatoesPengchao Li, Cunzhen Geng, Lingyu Li et al.Researches on low-molecular organic compounds are concentrated in amino acid and Humic acid chelating fertilizer, but few in sorbitol chelated calcium. In this study, selecting sorbitol as chelating agent, the technological conditions of chelating sorbitol with calcium and the effect of sorbitol chelated calcium on potato were studied. The impact factors on the stability of the fertilizer were investigated, including … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 9 Mar 2020 · 9,087 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparison and Analysis of Discrete Cosine Transform based Joint Photographic Experts Group Image Compression using Robust Watermarking AlgorithmS.M. Ramesh, Dr. A. ShanmugamProblem statement: The performance of the watermarking algorithms is analyzed using different compression standards to study the watermark extraction behavior of these algorithms. Approach: A digital watermarking method is said to be effective if the watermark embedded in an image by it could survive against diverse attacks ranging from compression, filtering to cropping. Several techniques are presented in the literature … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,680 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesigning a Generic Information Systems Audit Framework to Improve the Quality of Audit in Higher EducationElfadil A. Mohamed, Elgilani El. Elshareif, Omer Ishag Eldai MohamedThere are some similarities between Financial Statement Audit (FSA) and Information Systems Audit (ISA). FSA is an examination of the reliability and integrity of financial statement records, whereas ISA is a review and evaluation of the controls, risks and system development within an information systems infrastructure to ensure that the safeguards protect against abuse, protect assets, maintain data integrity and … …Journal of Computer Science, Vol. 15, Issue 5 · 10 May 2019 · 7,857 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDEVELOPMENT OF A PROXIMAL MACHINE VISION SYSTEM FOR OFF-SEASON WEED MAPPING IN BROADACRE NO-TILLAGE FALLOWSH. Liu, C. Saunders, S. H. LeeWeeds are among the most significant and costly environmental threats in Australian agriculture. Weeds compete with crop plants for moisture, nutrients and sunlight and can have a detrimental impact on crop yields and quality if uncontrolled. The distribution, size, density and species of the weeds are often heterogeneous in the cropping land. Instead of uniformly spray the same type of … …Journal of Computer Science, Vol. 9, Issue 12 · 26 Nov 2013 · 7,233 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn the Fly Negotiation for Urgent Service Level Agreement on Intercloud EnvironmentNawfal A. Mehdi, Ali Mamat, Hamidah Ibrahim, Shamala K. SubramaniamProblem statement: Impatient jobs are the jobs that have strict constraints in starting and completion time and need a fast response and attention in mapping to resources. The negotiation process in cloud computing needs a customer-provider agreement that leads to loss of a significant amount of time for impatient jobs. The huge increasing in cloud service providers makes selecting the … …Journal of Computer Science, Vol. 7, Issue 10 · 11 Aug 2011 · 7,948 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation of Global Positioning System Data for Offshore Platform DeformationAbdul Nasir Matori, Nurrohmat WidjajantiProblem statement: Reservoir compaction and shallow gas migration phenomena may cause offshore platform to experience deformation which if happens excessively will affect their structural integrity. Approach: Hence it is crucial to monitor and quantify the magnitude of the deformation especially if they are not uniform throughout the platform structure. However since mostly the offshore platforms are few hundreds kilometers away … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,698 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling and Control of Three-Phase Shunt Active Power FilterMoleykutty George, Kartik Prasad BasuIn this research the performance of a three-phase shunt active power filter (APF) using Model Reference Controller (MRC) has been compared with that using instantaneous active and reactive (p-q) theory. The novelty of this research lies in the application of MRC to generate the amplitude of the reference supply current required by the APF circuit and the successful implementation of … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,501 accessesView PDFCite
