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. In this … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 11 Nov 2014 · 6,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractCritical Aging Segments of Power Transmission LineH. H. Goh, N. E. Chin, Q. S. Chua et al.Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 9 Dec 2013 · 9,264 accessesView PDFCite
