Research ArticleOpen accessIn the keywordsUse of Maple to Analytically Solve the Equations of an Electrical Circuit Containing a Resistor, Diodes and Voltage GeneratorM’hamed El Aydi, Mohammed Barkatou, Rachid Bendaoud et al.The role of technology and the use of software in the educational process are growing in recent times. The use of software is essential especially if the analytical method available is too complicated for the students. In this study, we used the Maple software to deal with two physics problems, in the first problem we consider an electrical circuit containing … …Journal of Computer Science, Vol. 16, Issue 12 · 1 Dec 2020 · 6,463 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA New Approach to Model Concentrating PV Cells Under Non-Uniform IlluminationHang Zhou, Yuehong Su, Gang Pei et al.Concentrating PV (CPV) cells are often designed optimally depending on solar concentrator characteristics and operating conditions to ensure the best system performance. Before reaching a PV cell, solar radiation may experience some optical losses caused by the different physical phenomena occurring in a solar concentrator. A particular issue with the CPV technology is the non-uniformity of the concentrated radiation, which … …Energy Research Journal, Vol. 8, Issue 2 · 30 Aug 2017 · 7,137 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAnalysis of Time-Delayed Neural Networks via Rightmost Eigenvalue PositionsSun Yi, Sangseok Yu, Jung H. Kim, Taher M. Abu-LebdehNeural networks have been frequently used in various areas. In the implementation of the networks, time delays and uncertainty are present and known to lead to complex behaviors, which are hard to predict using classical analysis methods. In this study, stability and robust stability of neural networks considering time delays and parametric uncertainty is studied. For stability analysis, the rightmost … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 8,057 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTime-Delay Estimation using the Characteristic Roots of Delay Differential EquationsSun Yi, Wonchang Choi, Taher Abu-LebdehProblem statement: For ordinary dynamic systems (i.e., non-delayed), various methods such as linear least-squares, gradient-weighted least-squares, Kalman filtering and other robust techniques have been widely used in signal processing, robotics, civil engineering. On the other hand, time-delay estimation of systems with unknown time-delay is still a challenging problem due to difficulty in formulation caused. Approach: The presented method makes use … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 7 Apr 2012 · 8,082 accessesView PDF Cite
