Research ArticleOpen accessIn the abstractImpulse Volt-Time Characteristics of Oil and OIP InsulationS. Venkatesan, S. UsaEstimation of insulation strength of transformer oil and Oil Impregnated Paper (OIP) insulation, which constitutes major portion of insulation in power transformer, is an important task. Also, it is often necessary to evaluate the breakdown strength of oil and OIP under non-standard impulse voltages, since the oil and OIP insulation is subjected to non-standard waveshapes between inter-disc and inter-turn insulation. … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Fibre Content on Compressive and Flexural Properties of Coconut Fibre Reinforced Epoxy CompositesJasem G. Alotaibi, Ayedh Eid Alajmi, Belal F. Yousif, Nbhan D. SalihCoconut fibre reinforced polymer composites are gaining popularity in the field of engineering due to the many benefits that come with them such as low cost of production, easy fabrication, enhanced strength compared to other polymer composites. Of late, there has been an increase in the use of composites that are naturally based because they have many benefits. In line … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 20 Jun 2020 · 8,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand-Cover Removal and Gully Development in Southeast Nigeria: A 30-Year Analysis with Pixel and OBIA Approaches in JuxtapositionSylvanus IroIn this study a study of gully erosion in southeast Nigeria is presented. The study of gully development on a regional scale is currently undermined by the inherent costs associated with consistent field monitoring and the lack of historic measurements to perform time series analysis. As a result, there are very few studies which implement long term analyses of gullies … …American Journal of Environmental Sciences, Vol. 16, Issue 2 · 9 Jun 2020 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the use of Polyurethane Residue Aggregated to the Plaster of Civil ConstructionGuilherme Moraes de Oliveira, Vittória Caroline Souza dos Santos, José de Souza, Tatiana Louise Ávila C. RochaThe study deals with the reuse of Polyurethane (PU) obtained from a kitchen sponge added to plaster for use in civil engineering. The kitchen sponge is an item widely used by the population in their daily lives, generating a significant accumulation of waste. Thus, from the analysis of the properties of the kitchen sponge, it was seeking possible reuse of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 27 Nov 2019 · 7,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Method for Online Learning of Bayesian Network ParametersMariana D.C. Lima, Silvia M. NassarIn learning problems, there are situations where training data is not fully available at the learning time. They are incrementally generated by time, defining a type of domain called online that has among its characteristics the possibility of data failure or even missing data. In Bayesian networks, learning is divided into two categories: structure (related to the graph of conditional … …Journal of Computer Science, Vol. 15, Issue 3 · 16 Mar 2019 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractNano-Diamond Hybrid Materials for Structural Biomedical ApplicationRaffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuThe development of new diamond based bio-mechanically active hybrid nano-structured scaffolds for cartilage cells tissue engineering are proposed in this study. Innovative tissue engineering biomimetic materials based on hydrogel have shown attractive physical, biological and mechanical properties in several biomedical applications. A highly biocompatible novel hybrid material based on nanodiamonds and hydrophilic poly-(hydroxyl-ethyl-methacrylate) (pHEMA) is proposed. The aim of this … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 1 · 9 Mar 2017 · 9,183 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 abstractEffect of Sulfonated Acetone Formaldehyde (SAF) on the Firing Resistance and Aggressive Attach of SRC-SF Composite Cement PastesRanda M. Osman, S. Al-MasryThis work aimed to study the effect of the dosage of laboratory synthesized Sulfonated Acetone Formaldehyde (SAF) on the physic-mechanical characteristics and durability of SF-SRC cement pastes immersed in 4% MgCl2 or 4% MgSO4 solutions or at elevated temperatures up to 800°C. The compressive strength of thermally treatment cement pastes with 1.5% SAF increases up to 600°C, then decreases up … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 22 Jun 2015 · 7,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeophysical and Geological Studies of the Spread and Industrial Quality of Okurike Barite DepositAnthony E. Akpan, Ebong D. Ebong, Stephen E. Ekwok, Sackey JosephInvestors have been avoiding the Okurike Barite due to paucity of information on its economic worth in spite of the high demand for barites by the local industries. This study was embarked upon to determine the spread and industrial quality of the barite deposit in order to bridge the information gap. The Okurike Barite mineralised site was investigated using geophysical … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 22 Dec 2014 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractSEGMENTATION OF ELECTROENCEPHALOGRAM SIGNALS DURING EPILEPTIC SEIZURES BY USING FUZZY C-MEANSMuhammad Abdy, Tahir AhmadElectroencephalogram (EEG) is a recording of electrical activity of the brain. It contains valuable information related to the different physiological states of the brain. A quantitative EEG analysis has been developed over the years that introduce objective measure, reflecting not only the characteristics of the brain activity itself but also giving clues concerning the underlying associated neural dynamics.
