Research ArticleOpen accessIn the keywordsAsymptotic Behavior of an Artificial Neural Network Defined on Multipartite Directed GraphN. C. Majee, A. B. RoyProblem statement: Artificial Neural Network (ANN) are simple models to mimic some essential features of the complex central nervous system. ANN models are realistic due to their inherent stochastic nature of neural computation and strong synchronicity. Different ANN models are associated with directed and signed graphs. The present study proceeded by relaxing certain simplifying assumptions in the ANN model. Approach: … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,476 accessesView PDFCite
Literature ReviewOpen accessIn the abstractLiterature Study on Factors Influencing the Biochemical Analytes Stability in Blood, Serum and Plasma: Systematic ReviewSamia El Mahi, Asmae Tantane, Sanaa Ait Hamou, Said OubraimBlood testing represents an essential phase in diagnosis and treatment. It is important to comprehend the biochemical analytes' stability. This research gathers information from different journals that have investigated the stability of biochemical analytes under different conditions. This research aims to collect and analyze data about conditions that promote stability, conditions that lead to instability, and how stability varies in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 21 Aug 2024 · 5,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIFURCATION ANALYSIS OF EQUILIBRIUM POINT IN TWO NODE POWER SYSTEMHalima Aloui, Faouzi Bacha, Moncef GasmiThis study presents a study of bifurcation in a dynamic power system model. It becomes one of the major precautions for electricity suppliers and these systems must maintain a steady state in the neighborhood of the operating points. We study in this study the dynamic stability of two node power systems theory and the stability of limit cycles emerging from … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 29 Jan 2014 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Permanent Deformation of Pavement's Unbounded Layers Based on Cyclic Triaxial TestsB. ŽlenderThis research presents an analytical model for determining permanent deformation of pavement's sub-grade and unbound granular base and sub-base material due to cyclic traffic loading. The model is given for interpreting results of repeated load triaxial tests. It considers long term elastoplastic behavior and resilient behavior of sub-grade and unbound granular material. Permanent deformations are expressed as a function of … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,123 accessesView PDFCite
